Service Quality Monitoring<br />
Periodic QoS and QoE testing<br />
Slow setup time, service outages or unsuccessful data downloads are experienced in<br />
every network. In order to manage daily operations standardized matrices should be<br />
deployed by several divisions, e.g. Service Operations, Service Quality Assurance,<br />
Network Operations, International Roaming and Revenue Assurance.<br />
In a highly competitive market, such as<br />
the telecommunications industry, providing<br />
and maintaining highest quality to<br />
end customers is the key to a sustainable<br />
competitive advantage.<br />
With customers having multiple options<br />
at hand, poor quality – even the occasional<br />
drop in quality – can have immediate<br />
consequences. Switching between operators<br />
never has been easier through mobile<br />
number portability.<br />
First class service quality has many in� uencing<br />
factors not all being under the<br />
immediate control of the operator. Identi�<br />
cation of weak points can be di� cult<br />
and some may remain undiscovered even<br />
while their e� ects are still evident in the<br />
market.<br />

Test Quality of Service and Quality of Experience<br />
<strong>Keynote</strong> <strong>SIGOS</strong> o� ers accurate measurements<br />
of end-to-end quality for voice and<br />
data services by measuring KPIs like call<br />
setup success rates, HSDPA, HTTP average<br />
throughput or service degradation of<br />
BlackBerry services.<br />
Taking round the clock automated measurements<br />
at the end user’s interface (rather<br />
than in network nodes) operators obtain<br />
in-depth insight into end-user’s perception<br />
of the network.<br />
Generation of active test calls 24/7 –<br />
without the cost of 24/7 sta� - covering all<br />
aspects of the network and the upload of<br />
KPIs to a centralized alarming<br />
system provides excellent<br />
real-time feedback on<br />
the service levels of the<br />
network.<br />

Identi� cation and localization of service and network issues can be achieved before<br />

On-Demand Testing<br />
Perform reproducible ad-hoc testing!<br />
The customer service desk keeps getting complaints about certain service scenarios like<br />
‘BlackBerry e-mail service not reliable’, ‘basic voice calls not possible’ in certain locations,<br />
in the home country as well as abroad. Quick action needs to be taken!<br />
World-wide Testing<br />
<strong>Keynote</strong> <strong>SIGOS</strong> hosts the largest and<br />
most comprehensive world-wide test<br />
infrastructure, currently covering 4/5 of<br />
the world‘s countries. GlobalRoamer users<br />
bene� t from the availability and � exibility<br />
of the GlobalRoamer test network without<br />
the e� ort of running their own system.<br />
GlobalRoamer account holders log on and<br />
schedule their tests whenever the demand<br />
occurs. Being able to perform tests independently<br />
and without the usual hassles<br />
connected with doing business globally<br />
like time-zones is an invaluable asset!<br />
“If a real time test is needed, and it´s too<br />
late to contact a roaming partner, I can<br />
re-produce the test scenario identically.”<br />
The test call can be replicated repetitively<br />
in order to check whether service has<br />
been re-established.<br />
GlobalRoamer is deployed to survey<br />
speci� c services over roaming partners’<br />
networks managing both post-paid and<br />
prepaid SIMs across the di� erent technologies.<br />
The SIMs are co-located in <strong>Keynote</strong><br />
<strong>SIGOS</strong>’ premises in Nuremberg, Germany.<br />
Use Cases > Service Quality Monitoring<br />
Root causes can be localised easily when<br />
used in tandem with <strong>Keynote</strong> <strong>SIGOS</strong>’s<br />
integrated analysis tools.<br />
Time zone and business hours di� erences<br />
often make it di� cult to run tests with<br />
the co-operation of roaming partners.<br />
GlobalRoamer o� ers an easy and instant<br />
solution to this problem.<br />
“There is no time lost as we do not have to get in touch with the roaming partner. We can execute<br />
tests via GlobalRoamer in a matter of a few minutes anywhere in the world where <strong>SIGOS</strong> has coverage.<br />
Before we started to use GlobalRoamer sometimes we had to wait more than 3 months for<br />
execution of a roaming test because partners were occupied with other roaming partners’ tests.”<br />
“The <strong>SIGOS</strong> test system helps us to manage our test SIMs e� ciently as we do not have to send the<br />
SIMs to multiple countries for roaming testing. It provides us with a fully controlled test platform.<br />
We can perform multiple test cases easily and simultaneously.“<br />

Home Network Testing<br />
SITE enables network operators to test all<br />
relevant services in their network with a<br />
private test system. All locations covered<br />
by the private SITE system can be used for<br />
� exible end-to-end testing. Due to their<br />
modular structure, SITE test systems can<br />
range from a small local system to geographically<br />
widely distrubuted areas as well.<br />
The unique feature‚ ‘Global Resource Pool‘<br />
however, enables operators to expand the<br />
capability of their SITE system – no matter<br />
how small or big it may be – to reach out<br />
to world-wide test locations covering 4/5<br />
of the world‘s countries! In fact, they are<br />
enabled to utilize the huge network of<br />
GlobalRoamer test probes – all in one go!<br />

Network Diagnosis<br />
Model your network & � nd the root cause<br />
of service outages!<br />
Once periodic heartbeat testing for the services has been set up, very often Service<br />
Operations is the � rst team to detect service outages through the results of this active<br />
testing. But what network entity has caused the fault?<br />
SITE proves not only to be a good re� ection<br />
of real customer experience but also<br />
shows up bottlenecks in the network<br />
infrastructure via its solution Service<br />
Alarm Map (SAM).<br />
By supervision of all relevant end-customer<br />
services and correlation of network<br />
events it becomes possible to both<br />
anticipate and analyze service a� ecting<br />
network problems. A clear and comprehensive<br />
mapping of service problems to<br />
the performance of individual network<br />

elements and systems can then signi� -<br />
cantly drive down time back to service.<br />
Service Alarm Map helps to reduce the<br />
time for root cause identi� cation and<br />
supports the technical service teams with<br />
additional information like error-id, trace<br />
details & measurement values. This important<br />
drill-down functionality from service<br />
chain visualization to raw measurement<br />
values and trace information improves<br />
reaction times in the event of tra� c<br />
congestion and network element failures.<br />
“The number of customer complaints have been reduced signi� cantly due to network<br />
issues being identi� ed faster by the <strong>Keynote</strong> <strong>SIGOS</strong> test system. Real-time alerts and<br />
reports of incidents lead to faster resolution of the network issues identi� ed. Subscribers<br />
are “not fast enough” to call our Customer Care to lodge a complaint.”<br />

Drive Service Testing<br />
Test mobile subscriber experience on the move!<br />
SITE has already been widely deployed for periodic QoS testing and KPI generation.<br />
Quality of subscriber experience however is not only driven by static service use but<br />
also by service deployment on the move. Testing during moving is an important<br />
complementary approach in addition to stationary testing.<br />
SITE is a powerful tool for the delivery<br />
of Service Assurance and generation of<br />
leading Key Performance Indicators (KPIs)<br />
for operator networks, not only for static<br />
testing but also for mobility, simulating<br />
end user experience.<br />
Equivalent to the behavior of static Local<br />
Units, the SITE System collects a variety<br />
of network measurements from moving<br />
subscriber probes, known simply as Mobile<br />
Local Units (MLUs). These mobility tests<br />
are geared for vehicles like taxis, trucks or<br />
trains. Consequently they are called SITE<br />
‘Drive Service Tests’. The raw information<br />
is processed into KPIs and displayed in a<br />
Google Maps view or on a color coded<br />
geographic map.<br />

Content Testing / Handset Simulation<br />
Do all handsets work perfectly in your mobile network?<br />
The opportunity for mobile operators and advertisers to sell exciting new mobile<br />
content is enormous. However, the variety of available services like MMS, Video Streaming<br />
and Web Browsing may cause problems when using di� erent handsets, since<br />
the service platforms of the network react individually to each mobile phone type!<br />
Picture and text in wrong position<br />
Handset Simulation Test Concept Features:<br />
Data Services like Web and WAP browsing,<br />
streaming, MMS or video telephony are<br />
ARPU driving services.<br />
Premium content download is another<br />
huge revenue driver. Subscribers‘ expectations<br />
on quality of service are legitimately<br />
high.<br />
At the same time, handset speci� c behavior<br />
plays an important role in the delivery<br />
of this content and services.<br />
Delivered content not displayed in the expected<br />
format causes a de� nite negative<br />
impact on customers‘ Quality of Experience<br />
(QoE).<br />
How can new devices and services be<br />
properly tested in a cost-e� ective way<br />
that ultimately leads to customer satisfaction<br />
and increased revenue?<br />
The answer is automated testing while<br />
taking handset speci� cs into account –<br />
handset simulation.<br />
<strong>Keynote</strong> <strong>SIGOS</strong> provides a powerful handset<br />
simulation tool, integrated into the<br />
SITE and GlobalRoamer test systems.<br />
More than 1,000 virtual handsets are<br />
available from a ready-to-use and expandable<br />
library. Simulate the large variety<br />
of handsets without the e� ort of labor<br />

Benchmarking<br />
Who is the best performer?<br />
KPIs for own network are regularly reported to senior management. But how does your<br />
network perform compared to the competitors? Who has the best performance?<br />
Who o� ers the highest quality of service (QoS)? What is the quality situation for your<br />
international tra� c?<br />
In the competitive mobile environment,<br />
consistently high QoS is the deciding key.<br />
Benchmarking is an important dimension<br />
in making sure your services are competitive.<br />
National Approach<br />
Most measurement projects start o� with<br />
a national performance investigation and<br />
comparison after national network rollout<br />
has been completed. Operators have to<br />
� nd innovative ways to outperform their<br />
competition on network and service<br />
quality.<br />
With the SITE test system, network services<br />
can be benchmarked against the competition,<br />
measuring internationally approved<br />
and recognized Key Performance Indicators<br />
(KPIs) in a fast and easy way.<br />
International Approach<br />
In order to get a comprehensive overview<br />
of multinational or group-wide benchmarks,<br />
GlobalRoamer’s extensive global<br />
footprint can perform international benchmark<br />
tests and ensure improved cost<br />
e� ciencies.<br />
Benchmarking of international carriers is<br />
an important step in ensuring high quality<br />
of service for the international tra� c<br />
impacting your revenue.<br />
www.keynote-sigos.com<br />
Use Cases > Service Quality Monitoring<br />
Static Test Approach<br />
Network benchmark assessment is<br />
executed using an active end-to-end test<br />
scenario to observe the performance of<br />
your network from a subscriber point of<br />
view.<br />
Typical static benchmarking tests are<br />
performed at airports, city centres, mega<br />
sports or social event venues and hotspots<br />
where masses of people congregate.<br />
“On-the-Move” Test Approach<br />
Drive Service tests have the ability to cover<br />
di� erent geographical areas of locally<br />
competing networks rather than being<br />
focused on static locations.<br />
This simulates subscriber behavior<br />
moving from one cell to another and<br />
provides a comprehensive performance<br />
overview of the complete network.<br />
Service performance is benchmarked<br />
with national competitors as well as<br />
international operators:<br />

Inbound Roaming<br />
Provide best service to visitors in your network!<br />
Today, subscribers expect all frequently used mobile services to work reliably everywhere<br />
in the world. Thus, the quality and availability of services inside and outside the home<br />
network becomes increasingly important in the battle for customers!<br />
Inbound roaming has a big impact on your revenue and a long list of international<br />
roaming agreements may be desireable. It comes at a cost: each and every roaming<br />
agreement with a new roaming partner requires intense testing according to GSMA<br />
standards. In addition, periodic roaming tests with the most important roaming partners<br />
need to be performed. How can e� orts be reduced?<br />
Testing according to GSMA IREG standards<br />
is required whenever a new<br />
roaming partner is added. It can be a very<br />
time-consuming and exhaustive task. It<br />
may absorb your most expert sta� and<br />
repetitive testing can be just as expensive<br />
as the initial test setup – if performed<br />
manually!<br />
Therefore, test automation is key for cost<br />
e� ectiveness and operational e� ciency.<br />
With the SITE system your sta� will perform<br />
IREG speci� c tests in much shorter<br />
times with less e� ort – and the results will<br />
be easily reproducible!<br />
Implementation of testing for new roaming<br />
partners could not be easier: the<br />
SIM card is implemented into SITE‘s SIM<br />
Multiplexer which can be expanded to a<br />
capacity of more than 2,000 SIM cards.<br />
As soon as the SIM card has been implemented,<br />
sta� can run the necessary tests.<br />
Features for inbound roaming testing:<br />
Ready-to-use test cases are available for<br />
the execution of tests, according to IR 24,<br />
26, 27, 29,32, 35, 50, 60. These tests can be<br />
repeated at any given time!<br />
The test results are automatically processed<br />
into GSMA conformant reports<br />
ready for evaluation.<br />
SITE o� ers the right concept for inbound roaming testing:<br />
Core network test interfaces (A, Gb, IUCS, IUPS) for testing roaming, independently<br />
of radio speci� c problems<br />
Air interface testing for measuring real end-to-end behavior and experience<br />

Outbound Roaming Testing<br />
Assure QoS abroad to optimize and develop<br />
outbound roaming revenue<br />
The possiblility to travel the world quite easily is perceived as a matter of course nowadays.<br />
Traveling subscribers take availability and proper operation of all mobile services for granted.<br />
Outbound roaming contributes considerable revenue and therefore requires QoS assurance.<br />
Operators require information on service<br />
quality beyond their own network. To<br />
subscribers, perceived mobile quality<br />
when traveling abroad is vital, especially<br />
for corporate customers.<br />
Mobile operators need to ensure subscribers<br />
are able to log onto preferred roaming<br />
partners’ networks when traveling,<br />
whilst preserving consistently high levels<br />
of QoS to maintain long term business<br />
sustainability.<br />
When your subscribers arrive at a foreign<br />
destination, they expect their mobile<br />
service to work at all times.<br />
All relevant services need to be tested<br />
with at least each top roaming partner. If<br />
you depend on these partners to execute<br />
these required tests, it will be a huge task,<br />
considering availability of sta� , time zone<br />
di� erences and the like.<br />
The solution is the world‘s largest automated<br />
on-demand test network: Global-<br />
Roamer. Tests can be executed in more<br />
than 500 networks in three quarters of the<br />
world‘s countries. GlobalRoamer is hosted<br />
by <strong>Keynote</strong> <strong>SIGOS</strong> and can be accessed<br />
from anywhere in the world by logging on<br />
through a web interface.<br />
Why risk losing subscribers and roaming<br />
revenue, when the ability to test the performance<br />
of all your roaming partners is<br />
at your � ngertips?<br />
Standard services as well as complex<br />
technologies and services like Video Telephony,<br />
MMS and UMTS/HSDPA networks<br />
can be tested without the need for cooperation<br />
with your roaming partners and<br />
independently of time zone.<br />

SLA Testing according to GSMA GRQ<br />
Consistency & comparability of roaming QoS testing<br />
Since the tra� c in outbound roaming has a big value for operator revenue, it is important<br />
to monitor the most frequently visited roaming operators. The GSM Association has<br />
designed the right concept: GRQ.<br />
Roaming tra� c may be a low percentage<br />
of the entire network tra� c, but remains<br />
a signi� cant pro� t contributor.<br />
How to gain a global perspective on<br />

Roaming Hubbing Testing<br />
Connecting the world with a single roaming relationship<br />
Roaming hubs safeguard multi-lateral roaming and interworking relationships.<br />
How can a roaming hub concentrate on managing the key roaming priorities?<br />
Open Connectivity (OC) is replacing<br />
multiple bilateral roaming relationships<br />
between operators with a more e� cient<br />
hub-based approach. Open Connectivity<br />
enables multi-lateral roaming and interworking<br />
relationships via SMS hubbing<br />
and roaming hubbing.<br />
<strong>Keynote</strong> <strong>SIGOS</strong>’ world-wide, on-demand<br />
test platform caters for roaming hubs.<br />
It enables them to perform tests of Outbound<br />
Roaming services, IREG testing for<br />
Inbound Roaming, and QoS Monitoring,<br />
as well as GRQ testing.<br />
It improves operational and cost e� ciencies<br />
because of the automated test<br />
approach and real time reporting feature.<br />
Roaming hubbing providers are often<br />
tasked to actively monitor service availability<br />
and service quality on all their<br />
multilateral relations.<br />
GlobalRoamer allows the activation and<br />
testing of Roaming Hubbing customers’<br />
SIMs. It helps them to work more e� ciently<br />
to improve the quality of voice, data<br />
and SMS services for their customers.<br />

Roaming Steering Testing<br />
Are subscribers roaming with preferred roaming<br />
partners abroad?<br />
Steering of Roaming (SoR) has been rolled out by Operators in order to direct their outbound<br />
roamers to preferred VPMNs in the roaming destinations. Does it work?<br />
Steering of Roaming (SoR) solutions have<br />
been implemented by mobile operators<br />
in order to direct their outbound roamers<br />
to preferred VPMNs in each country. In<br />
some cases just one preferred VPMN in<br />
a country is chosen, in other cases SoR<br />
is about managing the proportion of<br />
revenue and tra� c shares between two or<br />
more VPMNs.<br />
SoR is the logical result of roaming/IOT<br />
agreements which are linked to volumes<br />
and percentages for one or more preferred<br />
VPMNs. On one hand it is a signi� cant<br />
commercial matter to detect short- or<br />
long-term deviations from these target<br />
distributions, on the other hand it is<br />
worthwhile to test potential deterioration<br />
of customer experience caused by SoR.<br />
Detection of Anti-Steering of Roaming is<br />
essential as operators may lose subscribers<br />
to non-preferred networks resulting<br />
in margin losses. Anti-steering is not only<br />
a breach to roaming agreements but may<br />
also lead to a bad roaming experience<br />
as the subscribers could be left without<br />
any coverage. Subscribers will not blame<br />

By detecting anti-steering activities, higher<br />
roaming costs can be avoided.<br />

Use Cases > International Carrier Quality Testing<br />
International Carrier Quality Testing<br />
Who is the best international carrier of choice?<br />
Setting up a call to a subscriber in a foreign country involves the choice of the relevant<br />
international interconnection carrier. How much impact has the interconnection carrier<br />
on QoS? Who is the best interconnection carrier partner?<br />
There is a need for both mobile and � xed<br />
operators to get a global perspective on<br />
interconnection service quality in order to<br />
maintain high levels of QoS to subscribers.<br />
The international interconnection quality<br />
experience is heavily in� uenced by the<br />
choice of the international carrier at the<br />
national boundary.<br />
Example of international CLI quality testing<br />
Testing with pre� xed called numbers requires<br />
knowledge about the current setup<br />
at the international gateway exchange.<br />
The deployment of an SS7 LU directly<br />
at the international gateway Exchange<br />
ensures dedicated interconnection carrier<br />
testing.<br />
Poor CLI and voice quality would inevitably<br />
decrease revenue and market share.<br />

By testing international carriers with an<br />
active monitoring system, you can not<br />
only monitor if the right calling number<br />
is displayed abroad but also the voice<br />
quality and call setup time, which can be<br />
e� ectively measured and reported.<br />
In addition, international carrier quality<br />
testing can be coupled with False Answer<br />
and SIM Box Detection.<br />
KPIs (examples):<br />
Received CLI on destination side<br />
CLI Indicator distinguishing the following<br />
cases:<br />
CLI from CgPN (“OK”)<br />
No CLI (“N”)<br />
Wrong CLI (“W”)<br />
Mean Opinion Score (PESQ MOS) for<br />

For example, if no CLI is received, there<br />
would be no possibility to call back and<br />
poor voice quality would result in short<br />
and frustrating conversations.<br />

Revenue Leakage & Fraud Detection<br />
Make sure your roaming revenues are not being detoured<br />
“Fraud“ - the word sounds quite exciting when it appears on a cinema billboard or a TV<br />
programme schedule but when it hits you personally, professionally, or in a corporate<br />
environment, it is much less enticing. Fraud will never be completely eliminated but, unless<br />
fraud management countermeasures are undertaken, it is unlikely that it will be reduced to<br />
a manageable level.<br />
SIM Box Detection<br />
The business goal is to gradually “clean” incoming tra� c terminating through SIM boxes<br />
by disconnecting all SIM Box numbers detected and to protect the network from any<br />
potential fraudulent upsurge in their use.<br />
SIM boxes have multiple negative e� ects<br />
on operators, roaming hub providers and<br />
customers alike, e.g.:<br />
revenue loss due to call redirection -<br />
roaming calls are intercepted, redirected<br />
and terminated via fraudulent SIM Box<br />
equipment.<br />
unnecessary investment due to service<br />
inaccessibility as a result of SIM Boxes<br />
creating false network congestion<br />
issues.<br />
revenue loss through CLI Quality<br />
Problems; immediate impact is the<br />
in-ability to „call back“.<br />
image loss through bad QoS as SIM<br />
Boxes often redirect calls over inadequate,<br />
highly compressed IP connections,<br />
resulting in poor voice quality.<br />

Early Charging Detection<br />
Get it right for your customers<br />
Use Cases > Revenue Leakage & Fraud Detection<br />
A common phenomenon is the scenario of Early or False Answer during voice call setup<br />
procedures. How do you detect and � ght these cases?<br />
Calls are being charged as if connected,<br />
without ever reaching the called party.<br />
The lack of Active End-to-End monitoring<br />
has led to millions of minutes being<br />
inaccurately billed to the originating<br />
calling parties worldwide. These fraudulent<br />
billings sometimes go unnoticed<br />
because the incremental billed call<br />
duration per user may be in the fraction<br />
of seconds.<br />
Prepaid SIMs used in GSM Gateways (SIM<br />
Boxes) could lead to false answers when<br />
the fraudulent SIM Box SIM credit has<br />
been consumed resulting in an announcement<br />
being played. In this instance the<br />
caller has to pay for the call connection<br />
leading to customer complaints and dissatisfaction<br />

Revenue Assurance<br />
Money makes the world go round – what happens if your<br />
network rating and billing is not correct?<br />
For all network operators validation of<br />
billing is of major importance. Operators<br />
must provide fair and accurate billing<br />
to the customer and also avoid revenue<br />
leakage or overcharges caused by services<br />
being incorrectly rated and invoiced. In<br />
most countries accuracy of metering and<br />
billing is mandatory to comply with legal<br />
regulations.<br />
As markets have become increasingly<br />
competitive, operators have used innovative<br />
tari� s, product and service bundles<br />
and discounts to di� erentiate themselves.<br />
Complex and fast changing tari� s inevitably<br />
create challenges in ensuring correct<br />
billing.<br />
How to guarantee correct billing?<br />
Three Revenue Assurance concepts<br />
are highlighted:<br />
Test Call/Event Generation<br />
CDR Testing<br />
Tari� Testing<br />
Test Call/Event Generation<br />
Test call and event generation can be as<br />
basic as creating network events by generating<br />
calls to test the correct function of a<br />
network or its subsystems.<br />
SITE is ideally suited as a Test Call/Event<br />
Generator for Revenue Assurance projects<br />
generating its CDRs to be referenced with<br />
the network’s ‘live ‘CDRs.<br />
Operators need to recognize the value of<br />
more than just test call generation; you<br />
need to be able to store CDRs to perform<br />
veri� cation and detection for errors<br />
AUTOMATICALLY.<br />
Testing that is both end-to-end and independent<br />
can provide the assurance that<br />
the customers are being correctly billed<br />
as well as satisfying compliance requirements.<br />
Today, manual tests not only provide inaccurate,<br />
untrustworthy but in most cases<br />
cost ine� cient testing. To ensure correct<br />
billing, a precise and reliable Revenue<br />
Assurance system is essential. With a<br />
SITE test system, continuous testing of<br />
all services provides maximum assurance<br />
that all calls are being correctly billed as<br />
each network element can be tested and<br />
veri� ed.<br />
The reliable Revenue Assurance<br />
solution comprising CDR<br />
generation, CDR comparison and<br />
tari� modeling is BABT certi� ed.<br />
New product pre-launch testing –<br />
can we bill accurately and reliably for<br />
the product?<br />
Testing of correct function after<br />
product updates – does the<br />
mediation system still summarize<br />
all CDRs correctly?<br />
Testing of software patching on<br />
switches and other infrastructure –<br />
are we still producing correct CDRs<br />
for all call classes?<br />
Testing new infrastructure during<br />
and after roll out, e.g. new base<br />
stations.<br />
Testing of roaming tari� updates –<br />
are roamers, still being billed?<br />
www.keynote-sigos.com
CDR Testing<br />
Timely detection of revenue leakages<br />
You want a solution which compares CDRs generated by network nodes like the MSC or<br />
SGSN in a highly automated way and sends alarms mismatches.<br />
SITE acts as a Test Call/Event Generator, it<br />
is capable of importing ‘live’ CDRs from the<br />
network and comparing them with the<br />
reference CDRs generated by SITE.<br />
The ‘live’ CDRs of the generated test calls<br />
are extracted at a chosen point in postprocessing<br />
for automated comparison by<br />
the test system.<br />
CDRs can be veri� ed and erroneous CDR<br />
� elds such as faulty time stamps and call<br />
duration can be detected.<br />

Tari� Testing<br />
Proactively monitor tari� plans against variety of test cases<br />
You want a solution which not only compares CDRs but also detects billing errors before<br />
they turn into customer complaints or revenue losses.<br />
Rating<br />
At the heart of the billing system is the<br />
rating engine. This takes the CDRs (call<br />
detail records) or IPDRs (internet protocol<br />
detail records) from the network, and<br />
then applies the appropriate rating plans<br />
to turn this information into rated CDRs<br />
ready to be associated with the customer.<br />

Billing<br />
Once a CDR has been rated it is applied to<br />
the customer‘s account, where discounts<br />
can be applied and from which a bill is<br />
created. Operators usually produce bills in<br />
cycles, spreading the load over a month<br />
or quarter and also evening out cash � ow.<br />
Within SITE your tari� model can be replicated.<br />
Thus, not only the raw data of CDRs<br />
can be compared but in addition also the<br />
correct billing of a service can be veri� ed.<br />
Thanks to SITE, fast regression testing<br />
of new pricing plans against a variety of<br />
test cases can be performed, detecting<br />

Prepaid SIM Recharging<br />
With prepaid subscribers you make substantial pro� ts<br />
Prepaid subscribers expect correct voucher recharging.<br />
<strong>Keynote</strong> <strong>SIGOS</strong> provides a tool to verify<br />
Prepaid SIM Card Recharging.<br />
SITE or GlobalRoamer have the ability to<br />
check if recharging procedures of prepaid<br />
cards has been performed successfully.<br />
Test Cases collect information about the<br />
current account balance and establish a<br />
call in the same way a subscriber does.<br />
That means entering vouchers using<br />
DTMF tones for navigating IVR menus or<br />
using USSD commands where supported.<br />
After a SIM card recharging attempt the<br />
account balance of a dedicated prepaid<br />
SIM card is re-checked and compared to<br />
balance before recharging attempt.<br />
www.keynote-sigos.com<br />
Besides using single vouchers (e.g. from<br />
scratch cards) for a single test, <strong>Keynote</strong><br />
<strong>SIGOS</strong> Test Systems support comprehensive<br />
voucher repository functionality<br />
managing numerous numbers.<br />
Further customer speci� c account veri-<br />

Fixed Network Testing<br />
NGN evolution calls for multi-technology testing<br />
With the explosive growth in the mobility arena, one could almost believe that the<br />
future of � xed networks was doomed. However, � xed networks continue to maintain<br />
their relevance, with technological evolution requiring new test approaches.<br />
Technological advances and the complex changeover from established technologies to<br />
new ones triggers the need for ensuring consistency of service quality over all underlying<br />
technologies.<br />
Poor service quality inevitably leads to loss of pro� t – if, for example, the line is bad the<br />
conversation will be short.<br />
With the SITE test system, <strong>Keynote</strong> <strong>SIGOS</strong> provides ONE platform for testing all technologies<br />
– � xed, mobile and IP-based, either within one technology or across technologies.<br />
Fixed network operators bene� t from SITE through:<br />

IP Network Testing<br />
Optimize your data network performance<br />
Slow access, error pages and unsuccessful orders? Just started VoIP services? Are you relying<br />
on your customers to � nd out about incidents, availability, speed and load issues?<br />
Mobile has made its impact on connecting<br />
the ‘last mile‘, particularly for voice<br />
communications, but has yet to make its<br />
impact on higher speed links and at least<br />
one mobile company has admitted that<br />
it cannot deliver the speeds contained in<br />
the 3G speci� cations.<br />
So where do � xed networks with IP connections<br />
beat radio-mobile? When capacities<br />
and speeds are high, where Internet<br />
access is required or where there are large<br />
� les to be downloaded, then the optical<br />
� bre link remains supreme, whether it<br />
is a link to a corporate client, a national<br />
backbone network or an international<br />
submarine cable system.<br />

Inside out – core network<br />

money<br />
Mobile Core<br />
Network Interfaces<br />
Core Network Testing<br />
Service Testing independent from Radio Problems<br />
Testing without Radio Access<br />
In some cases the active test approach<br />
of using test mobiles on an air interface<br />
can be counterproductive because radio<br />
speci� c problems can disturb results without<br />
adding any value. A typical example<br />
is roaming testing, where the problems<br />
come from the core network. For such<br />
cases there is bene� t in testing the services<br />
by means of simulating the radio<br />
access part, connecting directly to the<br />
core components such as the MSC, SGSN<br />
etc. without involving the radio access<br />
components.<br />
Typical use cases for testing<br />
without radio access part:<br />
Mobile Core Network<br />
Interactive Voice Response incl.<br />
interactive announcement tests<br />
Testing of Supplementary Services<br />
Testing of IN Services<br />
Inbound Roaming tests<br />
Load Tests on Core Network<br />
components<br />
Billing Testing via CDR tests<br />
Data Content Testing<br />
Handset Simulation<br />
etc.<br />
see page 2<br />
Regression Testing<br />
Another instance where connection direct<br />
to core network components is required is<br />
where tests need to be executed in a very<br />
short time. This is typically the case when<br />
network components like the MSC or<br />
SGSN have been updated or where the in-<br />
� uence of a high number of concurrently<br />
connected subscribers has to be checked<br />
immediately and automatically. Such<br />
kinds of regression testing can usually be<br />
executed in less than 20 minutes whilst<br />
still covering all services and subscriber<br />
pro� les.<br />
Typical use cases for regression<br />
testing without radio access part:<br />
Automated regression testing after<br />
upgrade/updates on:<br />
MSC (via GSM A)<br />
MSC and � xed network switches<br />
(via ISUP)<br />
SGSN (2.5G) via Gb<br />

SGSN via IuPS<br />
SMSC, MMSC<br />

Nomadic & Indoor Testing<br />
Portable local unit for � exible deployment and mass testing<br />
Indoor: Shopping and Exibition Centers or Airports – places of communication.<br />
But do mobile services work properly everywhere?<br />
There are a lot of interesting and revenue<br />
generating use cases for indoor testing.<br />
Especially in international airports where<br />
testing of inbound roaming characteristics<br />
is crucial to secure lucrative business.<br />
Also exhibition centers and shopping<br />
centers are typical buildings where<br />
subcribers very often experience lack of<br />
service. Furthermore it is worthwhile to<br />
mass-deploy the cost-e� cient nomadic<br />
units in o� ce towers with a lot of business<br />
customers. For indoor testing either the<br />
air interfaces or direct LAN connection can<br />
be recommended.<br />
Sports and Social Events: Testing campaign of short time frame and short notice.<br />
The Nomadic local unit is also ideally<br />
suited for short-term campaigns like<br />
sport events. A lot of sports fans gather at<br />
top level events like Formula 1 or soccer<br />
championships and expect high levels<br />
of service quality. Due to its fast installation<br />
the nomadic units can be quickly<br />
rolled out even at short notice. After easy<br />
deployment at temporary locations this<br />
autonomous system sends network information<br />
back via its air interfaces.<br />
Rural Areas: Where there are people there should be communication.<br />
Especially in remote areas it is often impossible<br />
to install local units, as no � xed<br />
IP connection is available. In this case the<br />
nomadic local unit is capable of establishing<br />
a permanent IP connection via<br />
GPRS/EDGE/HSPA modem. The connection<br />
is upheld via IPSec tunneling. By this<br />
means, test probes can be quickly installed<br />
in rural areas where you cannot rely<br />
on wired IP connections. The Nomadic<br />
local unit is the ideal solution for � exible<br />
deployment in the � eld.<br />

SITE<br />
One platform for all your End-to-End test requirements<br />
Challenge<br />
Today, network operators are confronted<br />
with an extremely dynamic market and<br />
the challenges of keeping up with new<br />
technology, permanent surveillance of<br />
Service Level Agreements (SLA) and reducing<br />
cost – whilst also maintaining customer<br />
satisfaction. Since these tests can be<br />
both, labor-intensive and costly they are<br />
too often neglected. To meet these challenges<br />
preventive and permanent Service<br />
Quality Assurance by means of End-to-End<br />
testing is essential.<br />
Get the full picture of your end users’<br />
experience (QoE) and act, instead of<br />
reacting to customer complaints<br />
Continuously monitor service<br />
availability, test and measure quality<br />
(KQI) and performance (KPI)<br />
Upfront testing ensures a smooth<br />
roll-out for new services and new<br />
technologies<br />
Initiate reproducible test cases which<br />
cannot be done with passive<br />
monitoring solutions<br />
Comprehensive network diagnosis,<br />

How does it work?<br />
Central SIM Multiplexing Technology – an Unparalleled ‘Teleporter’ for SIM Cards<br />
SIM cards are centrally hosted and virtually transmitted to any of the system’s remote<br />
test stations where the actual test is performed.<br />
SITE can handle thousands of SIM, USIM or Micro-SIM cards in cascade-style boards.<br />
Subscriber information from a SIM card is read out by the system and transmitted via a<br />
LAN/WAN network to any test location required.<br />
The SIM authentication procedure is handled virtually between the wireless interface in<br />
any location and the real SIM stored in the central SIM Multiplexer unit.<br />
Intuitive Workbench – Tailored to Users’ Speci� c Demands<br />
Comprehensive set of tools are available for Test Creation, Diagnosis as well as<br />
Alarming and Reporting to adapt SITE exactly to user demands. (see page 50)<br />

The SITE Architecture – Ensuring High-Performance, Security and Stability<br />
SITE runs on a stable, Linux based server solution o� ering highest standards<br />
of redundancy.<br />
SITE client workstations can be either Windows or Linux based.<br />
To ensure maximum performance, the SITE System uses an open SQL database.<br />
All con� guration information, test results, measurements and KPIs are stored logically,<br />
to provide clear measurement and reporting capabilities.<br />
Using powerful � lter functionality any database listing can be easily modi� ed and a<br />
multi-format export function allows the sharing of data with other network support<br />
tools.<br />

SITE can execute tests at any time desired. Via the scheduler window a single or group<br />
of tests can be de� ned once or periodically, based on very � exible selection criteria of<br />
date, day, time, frequency and number of repetitions.<br />
To avoid any resource con� ict, an intelligent resource management system controls<br />
access to interfaces and SIM cards, assuring smooth operation and maximum test<br />
parallelism.<br />
The self-management checks system components regularly and generates an alarm<br />
(SNMP-Trap) in the event of any failure.<br />

Globalize your SITE system and take o� with GRP!<br />
With Global Resource Pool your SITE system gets access to test probes all over the world<br />
Most SITE solutions are deployed for<br />
testing networks within national boundaries.<br />
Some existing SITE installations cover<br />
international testing by deploying SITE<br />
Local Units in neighboring countries for<br />
purposes of outbound roaming testing<br />
and fraud detection.<br />
The unique ‘Global Resource Pool’ (GRP)<br />
feature now allows users to connect private<br />
SITE systems with the world-wide network<br />
of GlobalRoamer test probes. By this,<br />
it means your local SITE system can get<br />
access to <strong>Keynote</strong> <strong>SIGOS</strong> hosted probes in<br />
more than 580 networks world-wide!<br />
As GRP connects to GlobalRoamer,<br />
which comes as a scalable pre-deployed<br />
infrastructure owned and managed by<br />
<strong>Keynote</strong> <strong>SIGOS</strong>, Operators are liberated<br />
from cumbersome manual implementation,<br />
operations and maintenance of these<br />

Reporting & Alarming<br />
Fully integrated in GlobalRoamer and SITE<br />
SITE and GlobalRoamer Reporting enables<br />
users to create, view and forward multiple<br />
reports. These reports are generated from<br />
measurements collected in the KPI database.<br />
These reports can either be based<br />
on <strong>Keynote</strong> <strong>SIGOS</strong> standard Key Performance<br />
Indicators (KPIs), customized KPIs<br />
or KPIs according to ETSI standards.<br />
Report creation is done by means of an<br />
easy drag-and-drop arrangement. SITE<br />
and GlobalRoamer Reporting o� ers the<br />
possibility to visualize test results using<br />
various graphical tools, serving even very<br />

Dashboard<br />
This Graphical User Interface (GUI) system<br />
tool provides a simpli� ed intelligent<br />
interface to SITE and GlobalRoamer reporting.<br />
It is of special interest to the people<br />
responsible for the service, who want<br />
to work intuitively without any training<br />
e� ort. KPIs can easily be � ltered and individually<br />
stored in a few clicks. Individual<br />
con� gurations allow additional, more<br />
customer-oriented, data analysis. Fast<br />
and easy drill down to individual traces is<br />
possible directly from the Dashboard.<br />
Matrix Report<br />
The Matrix Report environment allows the<br />
user to view Key Performance Indicator<br />
(KPI) data as a numerical value, which can<br />
be easily color coded to provide a quick,<br />
easy to understand overview of network<br />
performance. Service KPIs can therefore<br />
be displayed in a format which is especially<br />
useful for Network Management<br />
and Operations personnel.<br />
GIS<br />
For service testing “on the move”, a Google<br />
Maps based Geographical Information<br />
System (GIS) is integrated into SITE.<br />
Each drive test case collects position data<br />
from a GPS receiver during ”visibility“ of<br />
GPS satellites. These are displayed in a<br />
GIS. This means that after service testing<br />
a rich set of KPIs according to GPS data<br />
locally analysed, displayed on operator´s<br />
individual geographic maps or on Google<br />
Maps.<br />

with detailed parameter options. It is also<br />
possible to create customized test cases by<br />
means of the assembly of various test steps<br />
via a user-friendly drag-and-drop mechanism<br />
that SITE provides in its Test Case<br />
Editor environment. Complex scenarios<br />
can be quickly built to enable the testing<br />
of new network services.<br />
SITE Recorder<br />
This Tool allows intuitive automated recording<br />
of browsing actions taking handset<br />
characteristics into account.<br />
Mobile and provider speci� c web and<br />
WAP pages are retrieved from the network<br />
via the test probes during recording<br />
sessions to get a feel for real download<br />
behavior and latency. Traces are shown<br />
live while the developer is browsing.<br />
The test case can be evaluated before<br />
saving the entire browsing session for replay.<br />
Full feature support by the Test Case<br />
Editor makes later adaptation of recorded<br />
browsing sessions easy. It is like having<br />
full and instant remote control access to<br />
a speci� c handset or browser in a remote<br />
location – with no need to travel anywhere<br />
to use it.<br />
Control Structure<br />
The Control Structure enables test users<br />
to easily create tests at various locations<br />
and with di� erent SIM cards. It uses the<br />
logical operators:<br />
list based ”FOR EACH“<br />
condition based “REPEAT”<br />
time based ”WAIT“<br />
Test Sequence<br />
The goal of the test sequence concept is<br />
to save execution time by avoiding the<br />
resource consuming location update process<br />
being repeated for each subsequent<br />
test case.<br />
Usually a test case starts with a switched<br />
o� mobile terminal. The side-e� ect of this<br />
approach is that each test case has the<br />
following procedure:<br />
location update<br />
make a call (service test 1)<br />
switch o�<br />
Each of these steps often require more<br />
than one minute each to complete.<br />
For saving test execution time, an arbitrary<br />
number of service tests can be combined<br />
in one test sequence, which requires only<br />
a single location update.<br />
This e� ectively simulates typical mobile<br />
user behavior e.g.:<br />
switch on a mobile (location update)<br />
make a call (service test 1)<br />
send an SMS (service test 2)<br />
web browsing (service test 3)<br />
make a call (service test 4)<br />
switch o�<br />

Service Alarm Map<br />
The Service Alarm Map is used to visualize<br />
mobile network services that target<br />
a speci� c service area. Alarms that are<br />
generated by the failure or degraded<br />
performance of services can be linked<br />
to a speci� c network element within the<br />
operator’s infrastructure.<br />
This function is implemented by careful<br />
correlation between the speci� c elements<br />
used within a test case execution and the<br />
overall network topology which has supported<br />
the test scenario that generated<br />
the alarms.<br />

mobile station and core network.<br />
Optionally, the NAS traces are supplemented<br />
with traces of Radio Resource<br />
Control (RRC) signalling messages<br />
exchanged between the mobile and the<br />
radio access network. These RRC<br />
traces provide valuable additional<br />
information, facilitating monitoring and<br />

GPRS Attach<br />
Network Registration<br />
Fundamental for all mobile services!<br />
Each mobile subscriber wants to be able<br />
to communicate in the cellular telecommunications<br />
network without having to<br />
consider whether the network technology<br />
is 2G, 2.5G or 3G.<br />
This requires a successful mobile device<br />
registration on the base station subsystem<br />
(BSS). This is always the � rst step for<br />
further communication.<br />
Even if a call is not set up, the network<br />
needs to be able to communicate with<br />
the mobile handset to pinpoint where it<br />
is. Hence, a mobile network is divided into<br />
multiple cells (Base (Base Transceiver Transceiver Stations -<br />
BTS). And a a group group of cells is considered a a<br />
location area.<br />
A A mobile device in in motion keeps the the<br />
network network informed about changes in di� di� erent<br />
location areas. If the handset moves<br />
from a a cell in one location location area to a cell in<br />
another location area, area, the mobile device<br />
should perform a location area update to<br />
inform the network about the new locatilocation of the mobile device.<br />
Each <strong>Keynote</strong> <strong>SIGOS</strong> test case requires this<br />
successful network registration.<br />

Location Update procedure is performed:<br />
when the mobile device has been<br />

active, or<br />
when it is active but not involved in a<br />
call, and it moves from one location area<br />
to another, or<br />
after a regular time interval because of<br />
signal fade<br />
Some aspects of the registration procedure:<br />

Location Update for CS / PS<br />
Domain Registration<br />
Whenever a mobile device wants to obtain<br />
service from a cell, it must make sure<br />
beforehand that its subscriber’s SIM can<br />
be registered for that cell.<br />
By switching on the mobile device, it<br />
directly requests to update its current location<br />
information in the network. If this is<br />
performed successfully, the network acknowledges<br />
this with a message “Location<br />
Update Accept”. During this process, the<br />
network can ask for the mobile device’s<br />
identity and check it against reference<br />
data (Identi� cation and Authentication).<br />
When the service “con� dential subscriber<br />
identity” has been activated, a new Temporary<br />
Mobile Subscriber Identity (TMSI)<br />
assignment becomes a component of the<br />
location update. In this case enciphering<br />
of user data is activated and the new TMSI<br />
is transmitted together with the message<br />
“Location Update Accept”.<br />
The TMSI is used for security purposes, so<br />
that the International Mobile Subscriber<br />
Identity (IMSI) does not have to be transmitted<br />
over the air interface. The TMSI is<br />
a randomly assigned identity, which is<br />
updated each time the mobile device is<br />
in motion.<br />
GPRS Attach for mobile data<br />
connection<br />
GPRS Attach is the process during which<br />
the mobile device informs the packet<br />
core network about its presence in the<br />
network. The device usually initiates the<br />
GPRS attach after power on. The message<br />
sent to the new Serving GPRS Support<br />
Node (SGSN) contains the last assigned<br />
TMSI, location area information, etc.<br />
After the GPRS Attach, procedure when<br />
the mobile device is attached to SGSN<br />
and has been authorized, the mobile device<br />
is prepared for data communication.<br />
So when the mobile starts communication,<br />
it initiates establishing of Packet Data<br />
Protocol Context (PDP context activation).<br />

Do you o� er excellent Voice Quality?<br />
Voice Quality is, and will remain, the<br />
major key performance indicator for each<br />
operator’s network quality. This is recognized<br />
by subscribers and operators alike.<br />
Bad voice quality represents noise, echo,<br />
degraded tele-conversations and immediately<br />
sets a poor level of user satisfaction.<br />
International Carrier Voice Quality tests<br />
can reveal crucial quality information of<br />
di� erent network carriers and if it has<br />
been impacted by the usage of IP routing<br />
or SIM boxes. Therefore, veri� cation of<br />
voice quality is essential.<br />
Automated test methods with the intention<br />
to mimic subjective tests, allow for a<br />
cost e� ective and consistent alternative to<br />
subjective testing, either on a referenced<br />
or an unreferenced algorithm.<br />
Echo Testing<br />
In the course of the migration of 2G/3G<br />
Core Network (CN) and Radio Access<br />
Network (RAN) towards IP based transport<br />
solutions the importance of Echo measurements<br />
raises considerably.<br />
In SITE, the echo itself is generated<br />
arti� cially and its characteristics can be<br />
con� gured by the user. This allows for<br />
the simulation of well de� ned (acoustic)<br />
echoes that enables users to check whether<br />
the echo cancellers are con� gured<br />
correctly.<br />

Referenced Voice Quality testing is based<br />
on the ITU-T P.862 standard via the PESQ<br />
algorithm (Perceptual Evaluation of Speech<br />
Quality) and the ITU-T P.863 standard<br />
via the POLQA algorithm (Perceptual<br />
Objective Listening Quality Analysis).<br />
Both form the state-of-the-art techniques<br />
and international standards for automated<br />

Voice Quality is vitally important for any<br />
type of network that routes voice tra� c.<br />
With the shift from dedicated circuits to<br />
the e� ciency of IP based tra� c, it brings<br />
its inherent issues with regard to the<br />
end customer’s satisfaction with quality<br />
performance.<br />
Additional PESQ KPIs such as Real-time<br />
Transport Protocol (RTP), Jitter and Packet<br />
Loss are actively monitored.<br />
Performing checks on a comprehensive<br />
set of voice quality metrics ensures that<br />
IP networks run smoothly and problems<br />
are detected before they cause major<br />
disturbances leading to customer dissatisfaction.<br />

Test Systems > Applications > Voice Advanced<br />
In comparison to intrusive measurement<br />
techniques, such as PESQ, 3SQM is based<br />
on single ended measurements. In consequence,<br />
accuracy may not be as high<br />
but measurements can be worked on an<br />

Messaging<br />
Are your Messaging Services delivered reliably and on time?<br />
Short Message Service (SMS)<br />
Still the favored message service!<br />
SMS is the world-wide killer application<br />
for network operators.<br />
This simple network application results<br />
in large percentages of revenue for every<br />
mobile network operator. Therefore, this<br />
critical revenue stream would require constant<br />
active monitoring so as to achieve<br />
consistently high quality of service.<br />
SMS often su� ers from long delivery<br />
durations, modi� cation of content or<br />
missing text with multiple SMS messages.<br />
Due to roaming complexities, SMS messages<br />

Multimedia Messaging Service (MMS)<br />
When words are not enough!<br />
MMS are vital to the network operators’<br />
younger and higher ARPU (Average<br />
Revenue Per User) customers. With its<br />
complex functional combination of SMS<br />
and GPRS, it is easy for the service to<br />
become unavailable in a complex mobile<br />
network that is often being upgraded or<br />
optimized.<br />
In order to gain acceptance as a reliable<br />
service frequently used by the subscribers,<br />
network errors must be avoided and<br />
uncovered by performing active continuous<br />
tests.<br />
This will safeguard the reputational health<br />
of the operators and ensure high quality<br />
standards.<br />
Mobile IM<br />
Can your customers chat via Mobile Instant Messaging?<br />
The real time text based communication<br />
between two or more participants is popular<br />
on PC devices, e.g. Skype, ICQ, MSN,<br />
Yahoo, Google… etc. This instant messaging<br />
platform has made the leap from<br />
the PC to the mobile device, connecting<br />
friends, peers and colleagues while they<br />
are on the go.<br />
To get connected to either � xed or mobile<br />
IM users, Java applets are installed on<br />
mobile devices delivering branded IM<br />
user interfaces. A single device client may<br />
provide access to multiple IM systems<br />
which transmit and receive presence<br />
information.<br />
The device clients have to be compliant<br />
to the Open Mobile Alliance (OMA) Instant<br />

Value Added Services (VAS) are considered<br />
today’s driver of ARPU. Operators or<br />
third-party value-added service providers<br />
(VASP), also known as content providers,<br />
add value to standard service o� erings,<br />
encouraging subscribers to optimise their<br />

spending money on VAS, they naturally<br />
expect highest quality.<br />
Therefore, successful new VAS launch is<br />
mandatory while maintaining the consistently<br />
high quality customers have<br />
come to expect. The implementation of<br />
new VAS often involves complex interaction<br />
between network elements supplied<br />
by di� erent application content providers<br />
and, therefore, constant automated<br />

BlackBerry<br />
Your network`s sweetest fruit<br />
BlackBerry is one of today‘s leading<br />
wireless connectivity solutions for a large<br />
number of mobile business professionals<br />
found in enterprise and governmental<br />
organizations world-wide.<br />
It allows users to stay connected with<br />
secured wireless access to e-mail, corporate<br />
data, calendar and web, to easily<br />
manage all their communication and<br />
information from a single BlackBerry<br />
device whenever and wherever required.<br />
BlackBerry eliminates the hassles of<br />
dialup by moving mobile data to a “push”<br />
architecture.<br />
Especially for mobile professionals, it is<br />
vital that the network operator provides<br />
the highest levels of quality and reliability.<br />

Up with the hype on iPhone tests<br />
For many users, the iPhone and the 3G<br />
iPhone represents a new era of mobile<br />
phone interaction and services.<br />
The unique combination of multimedia<br />
content, intuitive multi-touch display<br />
controls, accelerometer and much more<br />
created strong demand for new operator<br />
services dedicated only for a unique<br />
group of users.<br />
Operators around the world specify this<br />
group of iPhone users as high-tech – high<br />
potential customers with distinctive technology<br />
and quality demands.<br />

Handset Simulation<br />
Do handsets work perfectly in your mobile network?<br />
The opportunity for mobile operators<br />
to sell exciting new mobile content and<br />
handsets is enormous, but the variety<br />
of available services like MMS, Video<br />
Streaming and Web Browsing may cause<br />
problems when using di� erent handsets.<br />
How can these new devices and services<br />
be properly tested in a cost-e� ective way<br />
that ultimately leads to increased revenue<br />
and customer satisfaction?<br />
We can help you with a powerful tool to<br />
test all your services, simulating the large<br />
variety of handsets in your network. No<br />
labor intensive and high-cost manual<br />
testing!<br />

Ensure end-to-end Quality of Service<br />
through delivery of Key Performance<br />
Indicators (KPIs) prepared for you by<br />
<strong>Keynote</strong> <strong>SIGOS</strong>. To reach a “snapshot” like<br />
view, a large number of tests in a short<br />
period of time (a few days or weeks) is<br />
executed and analyzed by <strong>Keynote</strong> <strong>SIGOS</strong>.<br />
The results are presented as combination<br />
of reports, graphs and text documents and<br />
can be the foundations for your benchmarks.<br />
QoS Monitoring<br />
With <strong>Keynote</strong> <strong>SIGOS</strong> you can easily prepare<br />
a long-term testing environment to ensure<br />
and monitor your Quality of Service. As<br />
an example, many customers constantly<br />
monitor the 50 to 100 most important<br />
roaming partners. Automatic tests and<br />
reports on Key Quality Indicators (KQIs)<br />
are prepared according to the customer’s<br />
wishes. Trained <strong>Keynote</strong> <strong>SIGOS</strong> experts<br />
manage<br />
reports for troubleshooting and provide<br />
test results in an easy to read format. SITE<br />
Tools like Dashboard and Service Alarm<br />
Map give signi� cant data on the actual<br />
network performance and functionality.<br />
Quality of Service monitoring with <strong>Keynote</strong><br />
<strong>SIGOS</strong> is an indispensable way for<br />
all departments of an operator to ensure<br />
high-class quality at all times.<br />
74 www.keynote-sigos.com
Roaming Steering Tests<br />
Test the functionality of steering programs.<br />
A number of location update tests<br />
in steered countries/networks are performed.<br />
The tests are examined by <strong>Keynote</strong><br />
<strong>SIGOS</strong> to discover whether the steering<br />
works as expected. From the distribution<br />
of tests over di� erent networks it is<br />
determined whether the planned steering<br />
ratios between di� erent networks are<br />
ful� lled.<br />
(page 24)<br />
Carrier Quality Tests<br />
It is of primary importance that Operators<br />
and Carriers o� er high quality transmission<br />
services. Operators can use <strong>Keynote</strong><br />
<strong>SIGOS</strong> to help ensure that their end<br />
customers enjoy the best possible quality<br />
services. By constantly monitoring the<br />
transmission quality of all connected carriers,<br />
tra� c can be routed intelligently to<br />
the best available. Carriers are interested<br />
to manage their SLAs with the Operators<br />
and to maximise the volume of tra� c<br />
coming from each operator. Since Operators<br />
may well route tra� c away from any<br />
carrier delivering poor quality transmission<br />
then the carriers have a vested interest<br />
in measuring their transmission quality.<br />
<strong>Keynote</strong> <strong>SIGOS</strong> can support carriers in<br />
understanding and monitoring the transmission<br />
quality of tra� c to more than 500<br />
operator networks world-wide.<br />
(page 25)<br />
Professional Services > Managed Services<br />
GRQ Tests<br />
Based on general experience of the<br />
outbound roaming market 80% of outbound<br />
roaming revenue comes from the<br />
top 20 roaming partners. For this reason<br />
the GSM Association recommends regular<br />
monitoring of service quality during outbound<br />
roaming with these top roaming<br />
partners. <strong>Keynote</strong> <strong>SIGOS</strong> has implemented<br />
a world-wide test system capable of<br />
measuring, reporting and alarming all<br />
aspects of roaming service quality using<br />
standard prepared test scenarios which<br />
can be used to regularly test, monitor<br />
and report on service quality in these top<br />
roaming partner networks using the SIM<br />
cards of the interested operators.<br />
<strong>Keynote</strong> <strong>SIGOS</strong> supported several operators<br />
during the GRQ trial phase and has<br />
successfully proven to be fully compliant<br />
to the GRQ framework.<br />
(page 22)<br />
Fraud Bypass Detection<br />
The internationally installed <strong>Keynote</strong><br />
<strong>SIGOS</strong> Test Systems can be used for Interconnect<br />
Fraud Bypass detection services.<br />
Access to alerts and detailed trace information<br />
is possible in real time allowing<br />
blocking of SIM Box numbers rapidly.<br />
All tests are provided as a fully managed<br />
service. Powerful reporting techniques<br />
allow benchmarking of SIM Box issues<br />
against historical values.<br />
