MGTS Universal Mobile Telecommunications System (UMTS) - Ixia

Ixia MGTS UMTS Solution
MGTS ® Universal Mobile
Telecommunications System
(UMTS)
The convergence of voice, data and video networks presents the telecom industry with many
exciting challenges. In response to those challenges, telecommunications equipment
manufacturers and service providers are competing fiercely to be the first to bring new
products to market. To assure the quality, performance and interoperability of those products,
Ixia offers the powerful Message Generator Traffic Simulator (MGTS). The MGTS ® product line
addresses diagnostic needs with easy-to-use, flexible and automated test solutions.
The MGTS product line spans wired and wireless technologies and is based on highperformance
platforms, the MGTS p250, p400 and m500. High level applications provide
sophisticated diagnostic capabilities for specific technologies: universal mobile telephone
system (UMTS); SS7, including SS7 over asynchronous transfer mode (ATM); generated packet
radio services (GPRS); and Internet protocol (IP).
The MGTS diagnostic system enables developers of third-generation (3G) network architectures
to create custom testers for radio network controller (RNC), UMTS terrestrial radio access
network (UTRAN), and core network elements. The MGTS can be used in all phases of
development:
• As a functional test tool during the protocol development phase of signaling products
during simulation
• As a load test tool during network modeling of serving nodes for protocol verification
and operational acceptance
• As an intelligent, high-load diagnostic tool for network integrity and peak performance

MGTS UMTS
The MGTS provides the protocols, simulators, interfaces, and applications required to build
custom environments for the following systems under test:
• RNC – The MGTS UMTS simulates node Bs and core network (MSC and SGSN portions
of UMTS) generating traffic over the lu or lub interfaces toward the RNC under test.
• Core Network (MSC and SGSN) – The MGTS UMTS simulates one or more UTRAN
networks, generating traffic over an lu interface toward a core network (MSC or SGSN)
under test.
• Gateway GPRSS Support Node (GGSN) – The MGTS UMTS simulates one or more
SGSNs generating traffic over the Gn interface toward the GGSN under test.

Functions and Load Testing
The UMTS test system can be used for functional testing or load testing. A functional test
provides for the early assessment of whether a design works. Once basic function is confirmed,
subsequent load testing can reveal how well the design intent is satisfied, under conditions that
approximate or exceed anticipated use.
The functional test features and tools are as follows:
• lu control signaling
• Adaptive multi-rate (AMR) voice call on lu
interface
• lu packet switched data
• lu unrestricted digital information
• IP Pass-through
The load test features and tools are as follows:
• control signaling load
• packet generator
• X-Stream Packet Generator load
• traffic generator
• macrodiversity
• Gn diagnostic system
• Gi simulator

Ixia MGTS UMTS Solution
Benefits:
• Provides custom test solutions
• Only one test tool is needed throughout the
product test cycle
• Quality of service measurements enable
performance to be tracked and measured
• Cases created for functional testing may be
used again for system and load testing
Protocol Adaptable State Machine
(PASM)
The MGTS utilizes PASM to enable the user to
construct custom test cases graphically in a non
programming environment. PASM is protocolindependent,
supporting standard and proprietary
protocols as well as variations from different countries.
