SOLVER for UMTS

Solver is a high-performance load and stress test tool for mobile telecommunication networks. It provides the ability to simulate an UMTS Terrestrial Radio Access Network (UTRAN) within a 3G network with a large number of connected mobile subscribers providing load and stress to the Core Network.

Solver makes it possible to generate and terminate calls and SMSs, perform speech quality measurements via PESQ, 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.

Solver for UMTS supports Iu-PS interface, (ATM and IP based) and Iu-CS interface, (ATM and IP based).

           

           

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.

TrFO

Solver provides load testing of TrFO over the IuCS interface.
