FREMONT, CA: GL Communications, a supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP, and VoIP networks, releases its new product Internet Protocol (IP) Multimedia Subsystem Network Simulation referred to as MAPS SIP IMS test suite.

Popularly known as IMS, the Internet Protocol (IP) Multimedia Subsystem is built on Session Initiation Protocol (SIP), a communications protocol for signaling and controlling multimedia communication sessions. By providing a unique convergence platform for different types of networks, IMS enables building of an efficient interoperating network. With an advanced network environment, GL’s MAPS SIP IMS test suite enables user to test their applications, devices, and services prior to deployment on a real-time network.

The key features of MAPS SIP IMS test suite includes:

The test suite simulates multiple User equipments (UEs) and IMS core elements such as P-CSCF, I-CSCF, S-CSCF, PCRF and MGCF. It supports both signaling and traffic simulation between any two IMS nodes and enables simulation of core network, access network, roaming architecture, interworking with other networks. By creating test environment, it allows user to test each IMS network elements independently using single interface simulation or multi interface simulation.

IMS core network can easily be integrated with 2G, 3G, 4G or any PSTN networks to test any call scenario using remote MAPS. Any applications and services can be tested using IMS core network. Remote MAPS application supports remote controlling/monitoring of all the interwork interfaces and elements. MAPS provides complete script based solution to build customized call scenarios.

The signaling and traffic simulation in a call is completely implemented using scripts. Commands in the scripts are executed in controlled way to simulate protocol and traffic behavior. MAPS application acts as either the Caller or resides at the network terminal acting as Callee. The Call Generation feature simulates an outgoing call by sending call control messages to the DUT using scripts and profiles. The profiles allow necessary parameters of call control messages to be changed during runtime. The call control scripts can also automatically handle the traffic over the established call. MAPS supports transmission and detection of various traffic types such as digits, voice file, single tone, dual tones, fax, sms, email, http, ftp, IVR, audio and video quality

 “MAPS SIP IMS test suite is capable of simulating multiple UEs and IMS core elements such as P-CSCF, I-CSCF, S-CSCF, PCRF, MGCF. With the help of mobile phones, and other simulated wireless networks, the VoLTE Lab setup can be operated in real-time for making VoLTE calls and also for interworking with PSTN and VoIP networks. It includes ready-to-use scripts, as per IETF specification. Test scripts include general messaging and call flow scenarios for multimedia call session setup and control over IP networks. Logging and pass/fail results are also reported. Test cases verify conformance of actions such as registration, call control, proxies and other servers,” says Karthik Ramalingam, Senior Manager for product development, GL Communications.
