Use Cases > Service Quality Monitoring 

See your network 

through the eyes of 

your customer 


Periodic QoS and QoE testing 

Slow setup time, service outages or unsuccessful data downloads are experienced in 

every network. In order to manage daily operations standardized matrices should be 

deployed by several divisions, e.g. Service Operations, Service Quality Assurance, 

Network Operations, International Roaming and Revenue Assurance. 

In a highly competitive market, such as 

the telecommunications industry, providing 

and maintaining highest quality to 

end customers is the key to a sustainable 

competitive advantage. 

With customers having multiple options 

at hand, poor quality – even the occasional 

drop in quality – can have immediate 

consequences. Switching between operators 

never has been easier through mobile 

number portability. 

First class service quality has many in� uencing 

factors not all being under the 

immediate control of the operator. Identi� 

cation of weak points can be di� cult 

and some may remain undiscovered even 

while their e� ects are still evident in the 

market. 

Active testing bene� ts 

Testing time 

Continuous heartbeat tests 

End user experience 

Best re� ection of end user experience: E2E service quality tests 

Test Quality of Service and Quality of Experience 

Keynote SIGOS o� ers accurate measurements 

of end-to-end quality for voice and 

data services by measuring KPIs like call 

setup success rates, HSDPA, HTTP average 

throughput or service degradation of 

BlackBerry services. 

Taking round the clock automated measurements 

at the end user’s interface (rather 

than in network nodes) operators obtain 

in-depth insight into end-user’s perception 

of the network. 

Generation of active test calls 24/7 – 

without the cost of 24/7 sta� - covering all 

aspects of the network and the upload of 

KPIs to a centralized alarming 

system provides excellent 

real-time feedback on 

the service levels of the 

network. 

Time to detect issues 

Identi� cation and localization of service and network issues can be achieved before 

actual service degradation and threat of revenue loss 

Operating costs 

Reduced operating costs by automating monitoring, testing, and reporting; 

increased personnel e� ciency; costs not correlated with network size and growth 

Testing scope 

Pro-active test approach can be realized; in control of testing scope 


On-Demand Testing 

Perform reproducible ad-hoc testing! 

The customer service desk keeps getting complaints about certain service scenarios like 

‘BlackBerry e-mail service not reliable’, ‘basic voice calls not possible’ in certain locations, 

in the home country as well as abroad. Quick action needs to be taken! 

World-wide Testing 

Keynote SIGOS hosts the largest and 

most comprehensive world-wide test 

infrastructure, currently covering 4/5 of 

the world‘s countries. GlobalRoamer users 

bene� t from the availability and � exibility 

of the GlobalRoamer test network without 

the e� ort of running their own system. 

GlobalRoamer account holders log on and 

schedule their tests whenever the demand 

occurs. Being able to perform tests independently 

and without the usual hassles 

connected with doing business globally 

like time-zones is an invaluable asset! 

“If a real time test is needed, and it´s too 

late to contact a roaming partner, I can 

re-produce the test scenario identically.” 

The test call can be replicated repetitively 

in order to check whether service has 

been re-established. 

GlobalRoamer is deployed to survey 

speci� c services over roaming partners’ 

networks managing both post-paid and 

prepaid SIMs across the di� erent technologies. 

The SIMs are co-located in Keynote 

SIGOS’ premises in Nuremberg, Germany. 


Root causes can be localised easily when 

used in tandem with Keynote SIGOS’s 

integrated analysis tools. 

Time zone and business hours di� erences 

often make it di� cult to run tests with 

the co-operation of roaming partners. 

GlobalRoamer o� ers an easy and instant 

solution to this problem. 

“There is no time lost as we do not have to get in touch with the roaming partner. We can execute 

tests via GlobalRoamer in a matter of a few minutes anywhere in the world where SIGOS has coverage. 

Before we started to use GlobalRoamer sometimes we had to wait more than 3 months for 

execution of a roaming test because partners were occupied with other roaming partners’ tests.” 

“The SIGOS test system helps us to manage our test SIMs e� ciently as we do not have to send the 

SIMs to multiple countries for roaming testing. It provides us with a fully controlled test platform. 

We can perform multiple test cases easily and simultaneously.“ 


Home Network Testing 

SITE enables network operators to test all 

relevant services in their network with a 

private test system. All locations covered 

by the private SITE system can be used for 

� exible end-to-end testing. Due to their 

modular structure, SITE test systems can 

range from a small local system to geographically 

widely distrubuted areas as well. 

The unique feature‚ ‘Global Resource Pool‘ 

however, enables operators to expand the 

capability of their SITE system – no matter 

how small or big it may be – to reach out 

to world-wide test locations covering 4/5 

of the world‘s countries! In fact, they are 

enabled to utilize the huge network of 

GlobalRoamer test probes – all in one go!

Network Diagnosis 

Model your network & � nd the root cause 

of service outages! 

Once periodic heartbeat testing for the services has been set up, very often Service 

Operations is the � rst team to detect service outages through the results of this active 

testing. But what network entity has caused the fault? 

SITE proves not only to be a good re� ection 

of real customer experience but also 

shows up bottlenecks in the network 

infrastructure via its solution Service 

Alarm Map (SAM). 

By supervision of all relevant end-customer 

services and correlation of network 

events it becomes possible to both 

anticipate and analyze service a� ecting 

network problems. A clear and comprehensive 

mapping of service problems to 

the performance of individual network

elements and systems can then signi� - 

cantly drive down time back to service. 

Service Alarm Map helps to reduce the 

time for root cause identi� cation and 

supports the technical service teams with 

additional information like error-id, trace 

details & measurement values. This important 

drill-down functionality from service 

chain visualization to raw measurement 

values and trace information improves 

reaction times in the event of tra� c 

congestion and network element failures. 

“The number of customer complaints have been reduced signi� cantly due to network 

issues being identi� ed faster by the Keynote SIGOS test system. Real-time alerts and 

reports of incidents lead to faster resolution of the network issues identi� ed. Subscribers 

are “not fast enough” to call our Customer Care to lodge a complaint.”

Drive Service Testing 

Test mobile subscriber experience on the move! 

SITE has already been widely deployed for periodic QoS testing and KPI generation. 

Quality of subscriber experience however is not only driven by static service use but 

also by service deployment on the move. Testing during moving is an important 

complementary approach in addition to stationary testing. 

SITE is a powerful tool for the delivery 

of Service Assurance and generation of 

leading Key Performance Indicators (KPIs) 

for operator networks, not only for static 

testing but also for mobility, simulating 

end user experience. 

Equivalent to the behavior of static Local 

Units, the SITE System collects a variety 

of network measurements from moving 

subscriber probes, known simply as Mobile 

Local Units (MLUs). These mobility tests 

are geared for vehicles like taxis, trucks or 

trains. Consequently they are called SITE 

‘Drive Service Tests’. The raw information 

is processed into KPIs and displayed in a 

Google Maps view or on a color coded 

geographic map. 

Drive Service Testing provides you with 

Service QoS KPIs (Voice Quality etc.) as 

well as many speci� c measurments 

(RxLevel, Handover, Call ID, MAIO...) 

Investment Protection 

Drive Service Tests are fully SITE compatible 

and can be performed as an 

extension to existing SITE systems 

securing current investment into 

Keynote SIGOS service assurance 

products. 



Unattended System 

SITE Drive Service Test is a completely 

autonomous system after installation. 

No engineer needs to be present in the 

vehicle for test setup, modi� cation or 

analysis. 

Easy Installation and Removal 

MLU is shipped fully pre-con� gured 

and only needs to be connected to the 

electronic on-board system. No further 

human interaction, not even switch-on 

is required. 

Geographic View 

SITE system delivers graphical views on 

your network quality. A comprehensive 

set of KPIs enriched with further information 

like speed of moving vehicle, altitude 

and position can be displayed on 

a map. Google Maps or WMS maps, e.g. 

operator’s own coverage map, display 

KPIs customizable by operator.

Content Testing / Handset Simulation 

Do all handsets work perfectly in your mobile network? 

The opportunity for mobile operators and advertisers to sell exciting new mobile 

content is enormous. However, the variety of available services like MMS, Video Streaming 

and Web Browsing may cause problems when using di� erent handsets, since 

the service platforms of the network react individually to each mobile phone type! 

Picture and text in wrong position 

Handset Simulation Test Concept Features: 

Data Services like Web and WAP browsing, 

streaming, MMS or video telephony are 

ARPU driving services. 

Premium content download is another 

huge revenue driver. Subscribers‘ expectations 

on quality of service are legitimately 

high. 

At the same time, handset speci� c behavior 

plays an important role in the delivery 

of this content and services. 

Delivered content not displayed in the expected 

format causes a de� nite negative 

impact on customers‘ Quality of Experience 

(QoE). 

How can new devices and services be 

properly tested in a cost-e� ective way 

that ultimately leads to customer satisfaction 

and increased revenue? 

The answer is automated testing while 

taking handset speci� cs into account – 

handset simulation. 

Keynote SIGOS provides a powerful handset 

simulation tool, integrated into the 

SITE and GlobalRoamer test systems. 

More than 1,000 virtual handsets are 

available from a ready-to-use and expandable 

library. Simulate the large variety 

of handsets without the e� ort of labor 

intensive manual testing.

Benchmarking 

Who is the best performer? 

KPIs for own network are regularly reported to senior management. But how does your 

network perform compared to the competitors? Who has the best performance? 

Who o� ers the highest quality of service (QoS)? What is the quality situation for your 

international tra� c? 

In the competitive mobile environment, 

consistently high QoS is the deciding key. 

Benchmarking is an important dimension 

in making sure your services are competitive. 

National Approach 

Most measurement projects start o� with 

a national performance investigation and 

comparison after national network rollout 

has been completed. Operators have to 

� nd innovative ways to outperform their 

competition on network and service 

quality. 

With the SITE test system, network services 

can be benchmarked against the competition, 

measuring internationally approved 

and recognized Key Performance Indicators 

(KPIs) in a fast and easy way. 

International Approach 

In order to get a comprehensive overview 

of multinational or group-wide benchmarks, 

GlobalRoamer’s extensive global 

footprint can perform international benchmark 

tests and ensure improved cost 

e� ciencies. 

Benchmarking of international carriers is 

an important step in ensuring high quality 

of service for the international tra� c 

impacting your revenue. 



Static Test Approach 

Network benchmark assessment is 

executed using an active end-to-end test 

scenario to observe the performance of 

your network from a subscriber point of 

view. 

Typical static benchmarking tests are 

performed at airports, city centres, mega 

sports or social event venues and hotspots 

where masses of people congregate. 

“On-the-Move” Test Approach 

Drive Service tests have the ability to cover 

di� erent geographical areas of locally 

competing networks rather than being 

focused on static locations. 

This simulates subscriber behavior 

moving from one cell to another and 

provides a comprehensive performance 

overview of the complete network. 

Service performance is benchmarked 

with national competitors as well as 

international operators:

Inbound Roaming 

Provide best service to visitors in your network! 

Today, subscribers expect all frequently used mobile services to work reliably everywhere 

in the world. Thus, the quality and availability of services inside and outside the home 

network becomes increasingly important in the battle for customers! 

Inbound roaming has a big impact on your revenue and a long list of international 

roaming agreements may be desireable. It comes at a cost: each and every roaming 

agreement with a new roaming partner requires intense testing according to GSMA 

standards. In addition, periodic roaming tests with the most important roaming partners 

need to be performed. How can e� orts be reduced? 

Testing according to GSMA IREG standards 

is required whenever a new 

roaming partner is added. It can be a very 

time-consuming and exhaustive task. It 

may absorb your most expert sta� and 

repetitive testing can be just as expensive 

as the initial test setup – if performed 

manually! 

Therefore, test automation is key for cost 

e� ectiveness and operational e� ciency. 

With the SITE system your sta� will perform 

IREG speci� c tests in much shorter 

times with less e� ort – and the results will 

be easily reproducible! 

Implementation of testing for new roaming 

partners could not be easier: the 

SIM card is implemented into SITE‘s SIM 

Multiplexer which can be expanded to a 

capacity of more than 2,000 SIM cards. 

As soon as the SIM card has been implemented, 

sta� can run the necessary tests. 

Features for inbound roaming testing: 

Ready-to-use test cases are available for 

the execution of tests, according to IR 24, 

26, 27, 29,32, 35, 50, 60. These tests can be 

repeated at any given time! 

The test results are automatically processed 

into GSMA conformant reports 

ready for evaluation. 

SITE o� ers the right concept for inbound roaming testing: 

Core network test interfaces (A, Gb, IUCS, IUPS) for testing roaming, independently 

of radio speci� c problems 

Air interface testing for measuring real end-to-end behavior and experience 

SIM Multiplexer: SIM cards can be managed centrally and securely for all roaming 

partners (as many as 2,000 SIM cards)

Outbound Roaming Testing 

Assure QoS abroad to optimize and develop 

outbound roaming revenue 

The possiblility to travel the world quite easily is perceived as a matter of course nowadays. 

Traveling subscribers take availability and proper operation of all mobile services for granted. 

Outbound roaming contributes considerable revenue and therefore requires QoS assurance. 

Operators require information on service 

quality beyond their own network. To 

subscribers, perceived mobile quality 

when traveling abroad is vital, especially 

for corporate customers. 

Mobile operators need to ensure subscribers 

are able to log onto preferred roaming 

partners’ networks when traveling, 

whilst preserving consistently high levels 

of QoS to maintain long term business 

sustainability. 

When your subscribers arrive at a foreign 

destination, they expect their mobile 

service to work at all times. 

All relevant services need to be tested 

with at least each top roaming partner. If 

you depend on these partners to execute 

these required tests, it will be a huge task, 

considering availability of sta� , time zone 

di� erences and the like. 

The solution is the world‘s largest automated 

on-demand test network: Global- 

Roamer. Tests can be executed in more 

than 500 networks in three quarters of the 

world‘s countries. GlobalRoamer is hosted 

by Keynote SIGOS and can be accessed 

from anywhere in the world by logging on 

through a web interface. 

Why risk losing subscribers and roaming 

revenue, when the ability to test the performance 

of all your roaming partners is 

at your � ngertips? 

Standard services as well as complex 

technologies and services like Video Telephony, 

MMS and UMTS/HSDPA networks 

can be tested without the need for cooperation 

with your roaming partners and 

independently of time zone. 


Use GlobalRoamer, the most extensive 

global infrastructure for automated active 

End-to-End testing hosted by Keynote 

SIGOS. With GlobalRoamer you can access 

an ever increasing number of world-wide 

networks through a web interface.

SLA Testing according to GSMA GRQ 

Consistency & comparability of roaming QoS testing 

Since the tra� c in outbound roaming has a big value for operator revenue, it is important 

to monitor the most frequently visited roaming operators. The GSM Association has 

designed the right concept: GRQ. 

Roaming tra� c may be a low percentage 

of the entire network tra� c, but remains 

a signi� cant pro� t contributor. 

How to gain a global perspective on 

roaming quality with consistent measurements 

and thus comparability between 

home network and visited networks? 

And how to achieve this goal in a

Roaming Hubbing Testing 

Connecting the world with a single roaming relationship 

Roaming hubs safeguard multi-lateral roaming and interworking relationships. 

How can a roaming hub concentrate on managing the key roaming priorities? 

Open Connectivity (OC) is replacing 

multiple bilateral roaming relationships 

between operators with a more e� cient 

hub-based approach. Open Connectivity 

enables multi-lateral roaming and interworking 

relationships via SMS hubbing 

and roaming hubbing. 

Keynote SIGOS’ world-wide, on-demand 

test platform caters for roaming hubs. 

It enables them to perform tests of Outbound 

Roaming services, IREG testing for 

Inbound Roaming, and QoS Monitoring, 

as well as GRQ testing. 

It improves operational and cost e� ciencies 

because of the automated test 

approach and real time reporting feature. 

Roaming hubbing providers are often 

tasked to actively monitor service availability 

and service quality on all their 

multilateral relations. 

GlobalRoamer allows the activation and 

testing of Roaming Hubbing customers’ 

SIMs. It helps them to work more e� ciently 

to improve the quality of voice, data 

and SMS services for their customers. 

Keynote SIGOS’ GlobalRoamer can add 

value to many aspects of the Roaming 

Hub business model. GlobalRoamer is an 

ideal enhancement to hubs.

Roaming Steering Testing 

Are subscribers roaming with preferred roaming 

partners abroad? 

Steering of Roaming (SoR) has been rolled out by Operators in order to direct their outbound 

roamers to preferred VPMNs in the roaming destinations. Does it work? 

Steering of Roaming (SoR) solutions have 

been implemented by mobile operators 

in order to direct their outbound roamers 

to preferred VPMNs in each country. In 

some cases just one preferred VPMN in 

a country is chosen, in other cases SoR 

is about managing the proportion of 

revenue and tra� c shares between two or 

more VPMNs. 

SoR is the logical result of roaming/IOT 

agreements which are linked to volumes 

and percentages for one or more preferred 

VPMNs. On one hand it is a signi� cant 

commercial matter to detect short- or 

long-term deviations from these target 

distributions, on the other hand it is 

worthwhile to test potential deterioration 

of customer experience caused by SoR. 

Detection of Anti-Steering of Roaming is 

essential as operators may lose subscribers 

to non-preferred networks resulting 

in margin losses. Anti-steering is not only 

a breach to roaming agreements but may 

also lead to a bad roaming experience 

as the subscribers could be left without 

any coverage. Subscribers will not blame

streamline roaming steering mechanisms 

such that outbound roaming revenues are 

optimized while maintaining high levels 

of end user satisfaction.

Use Cases > International Carrier Quality Testing 


Who is the best international carrier of choice? 

Setting up a call to a subscriber in a foreign country involves the choice of the relevant 

international interconnection carrier. How much impact has the interconnection carrier 

on QoS? Who is the best interconnection carrier partner? 

There is a need for both mobile and � xed 

operators to get a global perspective on 

interconnection service quality in order to 

maintain high levels of QoS to subscribers. 

The international interconnection quality 

experience is heavily in� uenced by the 

choice of the international carrier at the 

national boundary. 

Example of international CLI quality testing 

Testing with pre� xed called numbers requires 

knowledge about the current setup 

at the international gateway exchange. 

The deployment of an SS7 LU directly 

at the international gateway Exchange 

ensures dedicated interconnection carrier 

testing. 

Poor CLI and voice quality would inevitably 

decrease revenue and market share. 

Private SITE

Dedicated carrier 

route selection 

By testing international carriers with an 

active monitoring system, you can not 

only monitor if the right calling number 

is displayed abroad but also the voice 

quality and call setup time, which can be 

e� ectively measured and reported. 

In addition, international carrier quality 

testing can be coupled with False Answer 

and SIM Box Detection.

Use Cases > Revenue Leakage & Fraud Detection 

Identify leaks in your 

revenue stream 


Make sure your roaming revenues are not being detoured 

“Fraud“ - the word sounds quite exciting when it appears on a cinema billboard or a TV 

programme schedule but when it hits you personally, professionally, or in a corporate 

environment, it is much less enticing. Fraud will never be completely eliminated but, unless 

fraud management countermeasures are undertaken, it is unlikely that it will be reduced to 

a manageable level. 

SIM Box Detection 

The business goal is to gradually “clean” incoming tra� c terminating through SIM boxes 

by disconnecting all SIM Box numbers detected and to protect the network from any 

potential fraudulent upsurge in their use. 

SIM boxes have multiple negative e� ects 

on operators, roaming hub providers and 

customers alike, e.g.: 

revenue loss due to call redirection - 

roaming calls are intercepted, redirected 

and terminated via fraudulent SIM Box 

equipment. 

unnecessary investment due to service 

inaccessibility as a result of SIM Boxes 

creating false network congestion 

issues. 

revenue loss through CLI Quality 

Problems; immediate impact is the 

in-ability to „call back“. 

image loss through bad QoS as SIM 

Boxes often redirect calls over inadequate, 

highly compressed IP connections, 

resulting in poor voice quality. 

Call setup time is extended which leads 

to the impression of bad call quality 

from the home network operator.

Early Charging Detection 

Get it right for your customers 

Use Cases > Revenue Leakage & Fraud Detection 

A common phenomenon is the scenario of Early or False Answer during voice call setup 

procedures. How do you detect and � ght these cases? 

Calls are being charged as if connected, 

without ever reaching the called party. 

The lack of Active End-to-End monitoring 

has led to millions of minutes being 

inaccurately billed to the originating 

calling parties worldwide. These fraudulent 

billings sometimes go unnoticed 

because the incremental billed call 

duration per user may be in the fraction 

of seconds. 

Prepaid SIMs used in GSM Gateways (SIM 

Boxes) could lead to false answers when 

the fraudulent SIM Box SIM credit has 

been consumed resulting in an announcement 

being played. In this instance the 

caller has to pay for the call connection 

leading to customer complaints and dissatisfaction 

with the service rendered.

Use Cases > Revenue Assurance 

Ensure correct billing, 

for you and your 

customers 


Money makes the world go round – what happens if your 

network rating and billing is not correct? 

For all network operators validation of 

billing is of major importance. Operators 

must provide fair and accurate billing 

to the customer and also avoid revenue 

leakage or overcharges caused by services 

being incorrectly rated and invoiced. In 

most countries accuracy of metering and 

billing is mandatory to comply with legal 

regulations. 

As markets have become increasingly 

competitive, operators have used innovative 

tari� s, product and service bundles 

and discounts to di� erentiate themselves. 

Complex and fast changing tari� s inevitably 

create challenges in ensuring correct 

billing. 

How to guarantee correct billing? 

Three Revenue Assurance concepts 

are highlighted: 

Test Call/Event Generation 

CDR Testing 

Tari� Testing 

Test Call/Event Generation 

Test call and event generation can be as 

basic as creating network events by generating 

calls to test the correct function of a 

network or its subsystems. 

SITE is ideally suited as a Test Call/Event 

Generator for Revenue Assurance projects 

generating its CDRs to be referenced with 

the network’s ‘live ‘CDRs. 

Operators need to recognize the value of 

more than just test call generation; you 

need to be able to store CDRs to perform 

veri� cation and detection for errors 

AUTOMATICALLY. 

Testing that is both end-to-end and independent 

can provide the assurance that 

the customers are being correctly billed 

as well as satisfying compliance requirements. 

Today, manual tests not only provide inaccurate, 

untrustworthy but in most cases 

cost ine� cient testing. To ensure correct 

billing, a precise and reliable Revenue 

Assurance system is essential. With a 

SITE test system, continuous testing of 

all services provides maximum assurance 

that all calls are being correctly billed as 

each network element can be tested and 

veri� ed. 

The reliable Revenue Assurance 

solution comprising CDR 

generation, CDR comparison and 

tari� modeling is BABT certi� ed. 

New product pre-launch testing – 

can we bill accurately and reliably for 

the product? 

Testing of correct function after 

product updates – does the 

mediation system still summarize 

all CDRs correctly? 

Testing of software patching on 

switches and other infrastructure – 

are we still producing correct CDRs 

for all call classes? 

Testing new infrastructure during 

and after roll out, e.g. new base 

stations. 

Testing of roaming tari� updates – 

are roamers, still being billed? 


CDR Testing 

Timely detection of revenue leakages 

You want a solution which compares CDRs generated by network nodes like the MSC or 

SGSN in a highly automated way and sends alarms mismatches. 

SITE acts as a Test Call/Event Generator, it 

is capable of importing ‘live’ CDRs from the 

network and comparing them with the 

reference CDRs generated by SITE. 

The ‘live’ CDRs of the generated test calls 

are extracted at a chosen point in postprocessing 

for automated comparison by 

the test system. 

CDRs can be veri� ed and erroneous CDR 

� elds such as faulty time stamps and call 

duration can be detected.

Tari� Testing 

Proactively monitor tari� plans against variety of test cases 

You want a solution which not only compares CDRs but also detects billing errors before 

they turn into customer complaints or revenue losses. 

Rating 

At the heart of the billing system is the 

rating engine. This takes the CDRs (call 

detail records) or IPDRs (internet protocol 

detail records) from the network, and 

then applies the appropriate rating plans 

to turn this information into rated CDRs 

ready to be associated with the customer.

Billing 

Once a CDR has been rated it is applied to 

the customer‘s account, where discounts 

can be applied and from which a bill is 

created. Operators usually produce bills in 

cycles, spreading the load over a month 

or quarter and also evening out cash � ow. 

Within SITE your tari� model can be replicated. 

Thus, not only the raw data of CDRs 

can be compared but in addition also the 

correct billing of a service can be veri� ed. 

Thanks to SITE, fast regression testing 

of new pricing plans against a variety of 

test cases can be performed, detecting 

potential � aws in the billing process at a 

very early stage.

Prepaid SIM Recharging 

With prepaid subscribers you make substantial pro� ts 

Prepaid subscribers expect correct voucher recharging. 

Keynote SIGOS provides a tool to verify 

Prepaid SIM Card Recharging. 

SITE or GlobalRoamer have the ability to 

check if recharging procedures of prepaid 

cards has been performed successfully. 

Test Cases collect information about the 

current account balance and establish a 

call in the same way a subscriber does. 

That means entering vouchers using 

DTMF tones for navigating IVR menus or 

using USSD commands where supported. 

After a SIM card recharging attempt the 

account balance of a dedicated prepaid 

SIM card is re-checked and compared to 

balance before recharging attempt. 


Besides using single vouchers (e.g. from 

scratch cards) for a single test, Keynote 

SIGOS Test Systems support comprehensive 

voucher repository functionality 

managing numerous numbers. 

Further customer speci� c account veri-

Fixed Network Testing 

NGN evolution calls for multi-technology testing 

With the explosive growth in the mobility arena, one could almost believe that the 

future of � xed networks was doomed. However, � xed networks continue to maintain 

their relevance, with technological evolution requiring new test approaches. 

Technological advances and the complex changeover from established technologies to 

new ones triggers the need for ensuring consistency of service quality over all underlying 

technologies. 

Poor service quality inevitably leads to loss of pro� t – if, for example, the line is bad the 

conversation will be short. 

With the SITE test system, Keynote SIGOS provides ONE platform for testing all technologies

Optimize your data network performance 

Slow access, error pages and unsuccessful orders? Just started VoIP services? Are you relying

Mobile has made its impact on connecting 

the ‘last mile‘, particularly for voice 

communications, but has yet to make its 

impact on higher speed links and at least 

one mobile company has admitted that 

it cannot deliver the speeds contained in 

the 3G speci� cations. 

So where do � xed networks with IP connections 

beat radio-mobile? When capacities 

and speeds are high, where Internet 

access is required or where there are large 

� les to be downloaded, then the optical

is a link to a corporate client, a national 

backbone network or an international 

submarine cable system.

come from the core network. For such 

cases there is bene� t in testing the services 

by means of simulating the radio 

access part, connecting directly to the 

core components such as the MSC, SGSN 

etc. without involving the radio access 

components. 

Typical use cases for testing 

without radio access part: 

Mobile Core Network 

Interactive Voice Response incl. 

interactive announcement tests 

Testing of Supplementary Services 

Testing of IN Services 

Inbound Roaming tests 

Load Tests on Core Network 

components 

Billing Testing via CDR tests 

Data Content Testing 

Handset Simulation 

etc. 

see page 2 

Regression Testing 

Another instance where connection direct 

to core network components is required is 

where tests need to be executed in a very 

short time. This is typically the case when 

network components like the MSC or 

SGSN have been updated or where the in- 

� uence of a high number of concurrently 

connected subscribers has to be checked 

immediately and automatically. Such 

kinds of regression testing can usually be 

executed in less than 20 minutes whilst 

still covering all services and subscriber 

pro� les. 

Typical use cases for regression 

testing without radio access part: 

Automated regression testing after 

upgrade/updates on: 

MSC (via GSM A) 

MSC and � xed network switches 

(via ISUP) 

SGSN (2.5G) via Gb 

MSC-Server via IuCS 

SGSN via IuPS 

SMSC, MMSC 

WAP-, Web-, Mail-Server 

SCP testing including IN services 

and prepaid services 

etc. 

Typical advantages of 

core network testing: 

Not in� uenced by radio speci� c 

problems 

Fast execution of mass tests 

(e.g. thousands of tests in an hour) 

Quick results 

Detailed trace analyses with 

protocol stack information 


Use Cases > Nomadic & Indoor Testing 

Nomadic & Indoor Testing 

Portable local unit for � exible deployment and mass testing 

Indoor: Shopping and Exibition Centers or Airports – places of communication. 

But do mobile services work properly everywhere? 

There are a lot of interesting and revenue 

generating use cases for indoor testing. 

Especially in international airports where 

testing of inbound roaming characteristics 

is crucial to secure lucrative business. 

Also exhibition centers and shopping 

centers are typical buildings where 

subcribers very often experience lack of 

service. Furthermore it is worthwhile to 

mass-deploy the cost-e� cient nomadic 

units in o� ce towers with a lot of business 

customers. For indoor testing either the 

air interfaces or direct LAN connection can 

be recommended. 

Sports and Social Events: Testing campaign of short time frame and short notice. 

The Nomadic local unit is also ideally 

suited for short-term campaigns like 

sport events. A lot of sports fans gather at 

top level events like Formula 1 or soccer 

championships and expect high levels 

of service quality. Due to its fast installation 

the nomadic units can be quickly 

rolled out even at short notice. After easy 

deployment at temporary locations this 

autonomous system sends network information 

back via its air interfaces. 

Rural Areas: Where there are people there should be communication. 

Especially in remote areas it is often impossible 

to install local units, as no � xed 

IP connection is available. In this case the 

nomadic local unit is capable of establishing 

a permanent IP connection via 

GPRS/EDGE/HSPA modem. The connection 

is upheld via IPSec tunneling. By this 

means, test probes can be quickly installed 

in rural areas where you cannot rely 

on wired IP connections. The Nomadic 

local unit is the ideal solution for � exible 

deployment in the � eld.

How does it work? 

Central SIM Multiplexing Technology – an Unparalleled ‘Teleporter’ for SIM Cards 

SIM cards are centrally hosted and virtually transmitted to any of the system’s remote 

test stations where the actual test is performed. 

SITE can handle thousands of SIM, USIM or Micro-SIM cards in cascade-style boards. 

Subscriber information from a SIM card is read out by the system and transmitted via a 

LAN/WAN network to any test location required. 

The SIM authentication procedure is handled virtually between the wireless interface in 

any location and the real SIM stored in the central SIM Multiplexer unit. 

Intuitive Workbench – Tailored to Users’ Speci� c Demands 

Comprehensive set of tools are available for Test Creation, Diagnosis as well as 

Alarming and Reporting to adapt SITE exactly to user demands. (see page 50) 

Con� gurable user access rights 

User-friendly and intuitive Graphical User Interface which can be accessed from

The SITE Architecture – Ensuring High-Performance, Security and Stability 

SITE runs on a stable, Linux based server solution o� ering highest standards 

of redundancy. 

SITE client workstations can be either Windows or Linux based. 

To ensure maximum performance, the SITE System uses an open SQL database. 

All con� guration information, test results, measurements and KPIs are stored logically, 

to provide clear measurement and reporting capabilities. 

Using powerful � lter functionality any database listing can be easily modi� ed and a 

multi-format export function allows the sharing of data with other network support 

tools.

SITE can execute tests at any time desired. Via the scheduler window a single or group 

of tests can be de� ned once or periodically, based on very � exible selection criteria of 

date, day, time, frequency and number of repetitions. 

To avoid any resource con� ict, an intelligent resource management system controls 

access to interfaces and SIM cards, assuring smooth operation and maximum test 

parallelism. 

The self-management checks system components regularly and generates an alarm 

(SNMP-Trap) in the event of any failure. 


Globalize your SITE system and take o� with GRP! 

With Global Resource Pool your SITE system gets access to test probes all over the world 

Most SITE solutions are deployed for 

testing networks within national boundaries. 

Some existing SITE installations cover 

international testing by deploying SITE 

Local Units in neighboring countries for 

purposes of outbound roaming testing 

and fraud detection. 

The unique ‘Global Resource Pool’ (GRP) 

feature now allows users to connect private 

SITE systems with the world-wide network 

of GlobalRoamer test probes. By this, 

it means your local SITE system can get 

access to Keynote SIGOS hosted probes in 

more than 580 networks world-wide! 

As GRP connects to GlobalRoamer, 

which comes as a scalable pre-deployed 

infrastructure owned and managed by 

Keynote SIGOS, Operators are liberated 

from cumbersome manual implementation, 

operations and maintenance of these 

Remote Test Interfaces. 

GRP currently contains GSM Um and 

UMTS Uu interfaces which are all available 

for testing. 

Connect your local SITE system to the world-wide GlobalRoamer probes 

with the unique „Global Resource Pool“ feature!

Reporting & Alarming 

Fully integrated in GlobalRoamer and SITE 

SITE and GlobalRoamer Reporting enables 

users to create, view and forward multiple 

reports. These reports are generated from 

measurements collected in the KPI database. 

These reports can either be based 

on Keynote SIGOS standard Key Performance 

Indicators (KPIs), customized KPIs 

or KPIs according to ETSI standards. 

Report creation is done by means of an 

easy drag-and-drop arrangement. SITE 

and GlobalRoamer Reporting o� ers the 

possibility to visualize test results using 

various graphical tools, serving even very 

speci� c presentation and monitoring 

needs.

Strategy / KPI design 

KPI Database 

Flexible standard charts and diagrams 

as well as enhanced functionalities like 

“histograms”, “percentile”, “ad hoc reporting” 

and “derive to” can be immediately

Real time alarming is also embedded: 

resulting alarm noti� cations are automatically 

distributed via SMS, e-mail, SNMP, 

etc. to de� ned recipients. Users can de� ne 

threshold-settings, counters, severity 

triggering points, etc. which control when 

alarms should be generated or cleared. 

Reports can be illustrated in di� erent

Dashboard 

This Graphical User Interface (GUI) system 

tool provides a simpli� ed intelligent 

interface to SITE and GlobalRoamer reporting. 

It is of special interest to the people 

responsible for the service, who want 

to work intuitively without any training 

e� ort. KPIs can easily be � ltered and individually 

stored in a few clicks. Individual 

con� gurations allow additional, more 

customer-oriented, data analysis. Fast 

and easy drill down to individual traces is 

possible directly from the Dashboard. 

Matrix Report 

The Matrix Report environment allows the 

user to view Key Performance Indicator 

(KPI) data as a numerical value, which can 

be easily color coded to provide a quick, 

easy to understand overview of network 

performance. Service KPIs can therefore 

be displayed in a format which is especially 

useful for Network Management 

and Operations personnel. 

GIS 

For service testing “on the move”, a Google 

Maps based Geographical Information 

System (GIS) is integrated into SITE. 

Each drive test case collects position data 

from a GPS receiver during ”visibility“ of 

GPS satellites. These are displayed in a 

GIS. This means that after service testing 

a rich set of KPIs according to GPS data 

locally analysed, displayed on operator´s 

individual geographic maps or on Google 

Maps.

Test Creation Tools 

Easy and time saving con� guration! 


SITE provides large libraries of Test Cases 

for main network services in various formats 

with detailed parameter options. It is also 

possible to create customized test cases by 

means of the assembly of various test steps 

via a user-friendly drag-and-drop mechanism 

that SITE provides in its Test Case 

Editor environment. Complex scenarios 

can be quickly built to enable the testing 

of new network services. 

SITE Recorder 

This Tool allows intuitive automated recording 

of browsing actions taking handset 

characteristics into account. 

Mobile and provider speci� c web and 

WAP pages are retrieved from the network 

via the test probes during recording 

sessions to get a feel for real download 

behavior and latency. Traces are shown 

live while the developer is browsing. 

The test case can be evaluated before 

saving the entire browsing session for replay. 

Full feature support by the Test Case 

Editor makes later adaptation of recorded 

browsing sessions easy. It is like having 

full and instant remote control access to 

a speci� c handset or browser in a remote 

location – with no need to travel anywhere 

to use it. 

Control Structure 

The Control Structure enables test users 

to easily create tests at various locations 

and with di� erent SIM cards. It uses the 

logical operators: 

list based ”FOR EACH“ 

condition based “REPEAT” 

time based ”WAIT“ 

Test Sequence 

The goal of the test sequence concept is 

to save execution time by avoiding the 

resource consuming location update process 

being repeated for each subsequent 

test case. 

Usually a test case starts with a switched 

o� mobile terminal. The side-e� ect of this 

approach is that each test case has the 

following procedure: 

location update 

make a call (service test 1) 

switch o� 

Each of these steps often require more 

than one minute each to complete. 

For saving test execution time, an arbitrary 

number of service tests can be combined 

in one test sequence, which requires only 

a single location update. 

This e� ectively simulates typical mobile 

user behavior e.g.: 

switch on a mobile (location update) 


send an SMS (service test 2) 

web browsing (service test 3) 


switch o� 


Diagnosis Tools 

Keep the overview or go into details! 

Service Alarm Map 

The Service Alarm Map is used to visualize 

mobile network services that target 

a speci� c service area. Alarms that are 

generated by the failure or degraded 

performance of services can be linked 

to a speci� c network element within the 

operator’s infrastructure. 

This function is implemented by careful 

correlation between the speci� c elements 

used within a test case execution and the 

overall network topology which has supported 

the test scenario that generated 

the alarms. 

Layer 3 Tracing

Keynote SIGOS o� ers SIGOS o� ers Layer 

3 tracing for 2G, 3G and LTE which is very 

important for telecommunication network 

testing. The primary goal is to get a 

deeper insight into the message � ow and

Each piece of network information and 

trace is processed to provide signi� cant 

data on the actual network performance 

and functionality, � nally the data is combined 

to give a total service area view. 

SERVICE View 

With Service view you get 

an easy high level overview 

about the status of the whole 

network.

shooting the communication between 

mobile station and core network. 

Optionally, the NAS traces are supplemented 

with traces of Radio Resource 

Control (RRC) signalling messages 

exchanged between the mobile and the 

radio access network. These RRC 

traces provide valuable additional 

information, facilitating monitoring and 

troubleshooting of the Access Stratum 

(AS) as well. 

For 2G and LTE, Non-Access Stratum (NAS) 

Layer 3 tracing is supported.

Location Update 

GPRS Attach 


Fundamental for all mobile services! 

Each mobile subscriber wants to be able 

to communicate in the cellular telecommunications 

network without having to 

consider whether the network technology 

is 2G, 2.5G or 3G. 

This requires a successful mobile device 

registration on the base station subsystem 

(BSS). This is always the � rst step for 

further communication. 

Even if a call is not set up, the network 

needs to be able to communicate with 

the mobile handset to pinpoint where it 

is. Hence, a mobile network is divided into 

multiple cells (Base (Base Transceiver Transceiver Stations - 

BTS). And a a group group of cells is considered a a 

location area. 

A A mobile device in in motion keeps the the 

network network informed about changes in di� di� erent 

location areas. If the handset moves 

from a a cell in one location location area to a cell in 

another location area, area, the mobile device 

should perform a location area update to 

inform the network about the new locatilocation of the mobile device. 

Each Keynote SIGOS test case requires this 

successful network registration.

Location Update procedure is performed: 

when the mobile device has been

active, or 

when it is active but not involved in a 

call, and it moves from one location area 

to another, or 

after a regular time interval because of 

signal fade 

Some aspects of the registration procedure: 

make contact with the base station 

the mobile device registers to the 

network for access 

to start a voice and/or data session 

Network location registration is not 

only necessary for each call, but 

also for location based services like 

“friends-� nder”!

Location Update for CS / PS 

Domain Registration 

Whenever a mobile device wants to obtain 

service from a cell, it must make sure 

beforehand that its subscriber’s SIM can 

be registered for that cell. 

By switching on the mobile device, it 

directly requests to update its current location 

information in the network. If this is 

performed successfully, the network acknowledges 

this with a message “Location 

Update Accept”. During this process, the 

network can ask for the mobile device’s 

identity and check it against reference 

data (Identi� cation and Authentication). 

When the service “con� dential subscriber 

identity” has been activated, a new Temporary 

Mobile Subscriber Identity (TMSI) 

assignment becomes a component of the 

location update. In this case enciphering 

of user data is activated and the new TMSI 

is transmitted together with the message 

“Location Update Accept”. 

The TMSI is used for security purposes, so 

that the International Mobile Subscriber 

Identity (IMSI) does not have to be transmitted 

over the air interface. The TMSI is 

a randomly assigned identity, which is 

updated each time the mobile device is 

in motion. 

GPRS Attach for mobile data 

connection 

GPRS Attach is the process during which 

the mobile device informs the packet 

core network about its presence in the 

network. The device usually initiates the 

GPRS attach after power on. The message 

sent to the new Serving GPRS Support 

Node (SGSN) contains the last assigned 

TMSI, location area information, etc. 

After the GPRS Attach, procedure when 

the mobile device is attached to SGSN 

and has been authorized, the mobile device 

is prepared for data communication. 

So when the mobile starts communication, 

it initiates establishing of Packet Data 

Protocol Context (PDP context activation).

Do not ignore your core services! 

Voice services are fundamental to telecommunications 

companies. It is vital 

that the user experience of these services 

is measured continuously by active testing. 

Only this can assure the quality 

of this core service.

Interactive Voice Response (IVR) 

Do your voice response services work correctly? 

IVR services are deployed during Voicemail 

access and are a common feature 

of everyday life such as phone banking, 

ticketing and customer hotline services.

Voice Quality 

Do you o� er excellent Voice Quality? 

Voice Quality is, and will remain, the 

major key performance indicator for each 

operator’s network quality. This is recognized 

by subscribers and operators alike. 

Bad voice quality represents noise, echo, 

degraded tele-conversations and immediately 

sets a poor level of user satisfaction. 

International Carrier Voice Quality tests 

can reveal crucial quality information of 

di� erent network carriers and if it has 

been impacted by the usage of IP routing 

or SIM boxes. Therefore, veri� cation of 

voice quality is essential. 

Automated test methods with the intention 

to mimic subjective tests, allow for a 

cost e� ective and consistent alternative to 

subjective testing, either on a referenced 

or an unreferenced algorithm. 

Echo Testing 

In the course of the migration of 2G/3G 

Core Network (CN) and Radio Access 

Network (RAN) towards IP based transport 

solutions the importance of Echo measurements 

raises considerably. 

In SITE, the echo itself is generated 

arti� cially and its characteristics can be 

con� gured by the user. This allows for 

the simulation of well de� ned (acoustic) 

echoes that enables users to check whether 

the echo cancellers are con� gured 

correctly.

Referenced Voice Quality testing is based 

on the ITU-T P.862 standard via the PESQ 

algorithm (Perceptual Evaluation of Speech 

Quality) and the ITU-T P.863 standard 

via the POLQA algorithm (Perceptual 

Objective Listening Quality Analysis). 

Both form the state-of-the-art techniques 

and international standards for automated

Voice over IP Quality Testing 

Voice Quality is vitally important for any 

type of network that routes voice tra� c. 

With the shift from dedicated circuits to 

the e� ciency of IP based tra� c, it brings 

its inherent issues with regard to the 

end customer’s satisfaction with quality 

performance. 

Additional PESQ KPIs such as Real-time 

Transport Protocol (RTP), Jitter and Packet 

Loss are actively monitored. 

Performing checks on a comprehensive 

set of voice quality metrics ensures that 

IP networks run smoothly and problems 

are detected before they cause major 

disturbances leading to customer dissatisfaction. 


Test Systems > Applications > Voice Advanced 

In comparison to intrusive measurement 

techniques, such as PESQ, 3SQM is based 

on single ended measurements. In consequence, 

accuracy may not be as high 

but measurements can be worked on an 

analysis of the digital bit stream on an IP 

packet level. The measurement is limited 

to the transport stream analysis.

Short Message Service (SMS) 

Still the favored message service! 

SMS is the world-wide killer application 

for network operators. 

This simple network application results 

in large percentages of revenue for every 

mobile network operator. Therefore, this 

critical revenue stream would require constant 

active monitoring so as to achieve 

consistently high quality of service. 

SMS often su� ers from long delivery 

durations, modi� cation of content or 

missing text with multiple SMS messages. 

Due to roaming complexities, SMS messages 

may be “lost” resulting in non-delivery

complex functional combination of SMS 

and GPRS, it is easy for the service to 

become unavailable in a complex mobile 

network that is often being upgraded or 

optimized. 

In order to gain acceptance as a reliable 

service frequently used by the subscribers, 

network errors must be avoided and 

uncovered by performing active continuous 

tests. 

This will safeguard the reputational health 

of the operators and ensure high quality 

standards. 

Mobile IM 

Can your customers chat via Mobile Instant Messaging? 

The real time text based communication 

between two or more participants is popular 

on PC devices, e.g. Skype, ICQ, MSN, 

Yahoo, Google… etc. This instant messaging 

platform has made the leap from 

the PC to the mobile device, connecting 

friends, peers and colleagues while they 

are on the go. 

To get connected to either � xed or mobile 

IM users, Java applets are installed on 

mobile devices delivering branded IM 

user interfaces. A single device client may 

provide access to multiple IM systems 

which transmit and receive presence 

information. 

The device clients have to be compliant 

to the Open Mobile Alliance (OMA) Instant

Today’s driver of ARPU! 

Value Added Services (VAS) 

Is your ARPU driver up and running? 

Value Added Services (VAS) are considered 

today’s driver of ARPU. Operators or 

third-party value-added service providers 

(VASP), also known as content providers, 

add value to standard service o� erings, 

encouraging subscribers to optimise their 

mobile phone usage. With subscribers 

spending money on VAS, they naturally 

expect highest quality. 

Therefore, successful new VAS launch is 

mandatory while maintaining the consistently 

high quality customers have 

come to expect. The implementation of 

new VAS often involves complex interaction 

between network elements supplied 

by di� erent application content providers 

and, therefore, constant automated

Handset oriented testing 

So many features for each new device! 

BlackBerry 

Your network`s sweetest fruit 

BlackBerry is one of today‘s leading 

wireless connectivity solutions for a large 

number of mobile business professionals 

found in enterprise and governmental 

organizations world-wide. 

It allows users to stay connected with 

secured wireless access to e-mail, corporate 

data, calendar and web, to easily 

manage all their communication and 

information from a single BlackBerry 

device whenever and wherever required. 

BlackBerry eliminates the hassles of 

dialup by moving mobile data to a “push” 

architecture. 

Especially for mobile professionals, it is 

vital that the network operator provides 

the highest levels of quality and reliability.

Up with the hype on iPhone tests 

For many users, the iPhone and the 3G 

iPhone represents a new era of mobile 

phone interaction and services. 

The unique combination of multimedia 

content, intuitive multi-touch display 

controls, accelerometer and much more 

created strong demand for new operator 

services dedicated only for a unique 

group of users. 

Operators around the world specify this 

group of iPhone users as high-tech – high 

potential customers with distinctive technology 

and quality demands.

test procedures performed via SITE or 

GlobalRoamer without any additional effort. 

At the same time, measurements and 

KPIs provide clear evidence of the service

Do handsets work perfectly in your mobile network? 

The opportunity for mobile operators 

to sell exciting new mobile content and 

handsets is enormous, but the variety 

of available services like MMS, Video 

Streaming and Web Browsing may cause 

problems when using di� erent handsets. 

How can these new devices and services 

be properly tested in a cost-e� ective way 

that ultimately leads to increased revenue 

and customer satisfaction? 

We can help you with a powerful tool to 

test all your services, simulating the large 

variety of handsets in your network. No 

labor intensive and high-cost manual 

testing!

Performance Tests 

Ensure end-to-end Quality of Service 

through delivery of Key Performance 

Indicators (KPIs) prepared for you by 

Keynote SIGOS. To reach a “snapshot” like 

view, a large number of tests in a short 

period of time (a few days or weeks) is 

executed and analyzed by Keynote SIGOS. 

The results are presented as combination 

of reports, graphs and text documents and 

can be the foundations for your benchmarks. 

QoS Monitoring 

With Keynote SIGOS you can easily prepare 

a long-term testing environment to ensure 

and monitor your Quality of Service. As 

an example, many customers constantly 

monitor the 50 to 100 most important 

roaming partners. Automatic tests and 

reports on Key Quality Indicators (KQIs) 

are prepared according to the customer’s 

wishes. Trained Keynote SIGOS experts 

manage 

reports for troubleshooting and provide 

test results in an easy to read format. SITE 

Tools like Dashboard and Service Alarm 

Map give signi� cant data on the actual 

network performance and functionality. 

Quality of Service monitoring with Keynote 

SIGOS is an indispensable way for 

all departments of an operator to ensure 

high-class quality at all times. 


Roaming Steering Tests 

Test the functionality of steering programs. 

A number of location update tests 

in steered countries/networks are performed. 

The tests are examined by Keynote 

SIGOS to discover whether the steering 

works as expected. From the distribution 

of tests over di� erent networks it is 

determined whether the planned steering 

ratios between di� erent networks are 

ful� lled. 

(page 24) 

Carrier Quality Tests 

It is of primary importance that Operators 

and Carriers o� er high quality transmission 

services. Operators can use Keynote 

SIGOS to help ensure that their end 

customers enjoy the best possible quality 

services. By constantly monitoring the 

transmission quality of all connected carriers, 

tra� c can be routed intelligently to 

the best available. Carriers are interested 

to manage their SLAs with the Operators 

and to maximise the volume of tra� c 

coming from each operator. Since Operators 

may well route tra� c away from any 

carrier delivering poor quality transmission 

then the carriers have a vested interest 

in measuring their transmission quality. 

Keynote SIGOS can support carriers in 

understanding and monitoring the transmission 

quality of tra� c to more than 500 

operator networks world-wide. 

(page 25) 

Professional Services > Managed Services 

GRQ Tests 

Based on general experience of the 

outbound roaming market 80% of outbound 

roaming revenue comes from the 

top 20 roaming partners. For this reason 

the GSM Association recommends regular 

monitoring of service quality during outbound 

roaming with these top roaming 

partners. Keynote SIGOS has implemented 

a world-wide test system capable of 

measuring, reporting and alarming all 

aspects of roaming service quality using 

standard prepared test scenarios which 

can be used to regularly test, monitor 

and report on service quality in these top 

roaming partner networks using the SIM 

cards of the interested operators. 

Keynote SIGOS supported several operators 

during the GRQ trial phase and has 

successfully proven to be fully compliant 

to the GRQ framework. 

(page 22) 

Fraud Bypass Detection 

The internationally installed Keynote 

SIGOS Test Systems can be used for Interconnect 

Fraud Bypass detection services. 

Access to alerts and detailed trace information 

is possible in real time allowing 

blocking of SIM Box numbers rapidly. 

All tests are provided as a fully managed 

service. Powerful reporting techniques 

allow benchmarking of SIM Box issues 

against historical values.
