SOLVER for GSM/GPRS

Solver is a high performance load and stress test tool for mobile telecommunication networks. It provides the ability to simulate a Radio Access Network for GSM (2G) and GPRS (2,5G) with a large number of connected mobile subscribers providing load to the Core Network.

Solver GSM simulates the RAN sending traffic over the A-Interface (or ATER), between the simulated BSC and the Core Network, an MGW or an MSC.

Solver can generate and terminate calls and SMSs, configure the simulated access network, test network indicators and provide real-time statistics on traffic progress. Various traffic patterns are easily created to run simultaneously or in sequence. You can choose to run with or without User Plane data.

           

           

Main features

  • Originate and terminate calls with Control Plane signaling and User Plane (payload).
  • Provides fine-grain control over call set-up rates and parameters.
  • Emulates Radio Access Networks – Core Network communication procedures.
  • Displays call activity and completion statistics such as set-ups, releases and active calls on-line.
  • Generates high traffic load towards the Core Network.
  • Supports set-up and release of GTP tunnels over the Packet Switched Core Network.
  • Displays Radio Access Network statistics.
           

Add-on applications

Handover

Solver can simulate single or multiple handovers between 2G-2G, 2G-3G, and 3G-3G.

MSC in Pool (MiP)

Solver can distribute traffic load. The MiP functionality is primarily used for load balancing over MSCs or load redistribution, for example removing load from one MSC during maintenance.

PESQ

Verify speech quality by using PESQ measurements on several simultaneous calls, while at the same time generating heavy background traffic.

SMS

With Solver, it is possible to perform SMS generation and termination with user-definable message content.

TFO

In Tandem Free Operation, Solver provides load-testing of end-to-end codec and rate negotiation.
