GSM GPRS EDGE Simulators

PRISMA has more than 10 years of wireless protocol simulator expertise and spends heavily in R&D to provide support for all kinds of simulation scenarios for different network topologies, equipment vendors, traffic quantities or traffic types (circuit switched, packet switched).
Thanks to its scalability and modularity, the LSU family can be used during every phase of development. The hardware configuration and the installed software can be adapted to meet the requirements and challenges of any testing.

Software Development

Line Server Unit (LSU) is used to monitor and decode all the protocol stacks (standard or vendor dependent) at every interface of a GSM/GPRS/EDGE network. Software engineers can simulate every operating condition by a powerful set of libraries for each protocol. Scripts are written in Tcl/Tk or generated by third parties software (SDL/TTCN editors) integrated with LSU command interface.

Integration

LSU is used as multi-interface monitor to verify network behavior by message exchange between network elements and to debug abnormal conditions. A set of dedicated features has been studied following customers requests to reproduce network element failures, faulty links, variable delays due to different network topology. Look at Drop/Insert utility and Satellite Delay for details.

Load & Stress

LSU is used to inject a huge traffic at every interface of the element under test in order to verify its robustness. Simulation results are analyzed in real-time or by post-processing. The scalability of LSU allows to increase the number of lines and processing power from a few lines up to hundreds of lines at wire-speed running tests in parallel over one or more network elements under stress.

Examples of Network Element Simulators:

 Abis Simulator

BTS simulation, dynamic Abis, mobile phone population, handover, congestion, circuit switch traffic.

 Gb Simulators

SGSN simulation in labs where connection to a real SGSN doesn’t exist, simulation of multiple BSS for SGSN load & stress

 EDGE Load & Stress

Up to now the LSU is the most powerful system for load & stress of EDGE network elements able to simulate thousands of mobile phone-originating EDGE sessions over hundreds of lines, with exceptional performance.

 MSC Simulator

For functional test and Load & Stress of the BSS equipment.
