Solver is a high-performance load, stress, and feature test tool for SIP, PSTN, 2G, 2.5G, 3G, and 4G telecommunications networks. It provides the ability to simulate a Radio Access Network (RAN/UTRAN/E-UTRAN) for GSM/GPRS, UMTS and LTE with a huge number of connected mobile subscribers providing load to the Core Network.You can do this, with Polystar's load and stress testing solution that simplifies qualitative performance analysis for equipment manufacturers, network operators and enterprises.

The BSCs and RNCs are connected to the MGW/MSC/VLRs and SGSNs respectively, and to the different BTSs and Node Bs, which in turn communicate with the mobile devices. 

Various traffic patterns can be flexibly created to run simultaneously or in sequence in order to simulate real-world call traffic patterns.

Solver easily produces load in different steps - everything from background load to maximum testing, as well as various basic call scenarios existing in a network to fill the queues and load the processors and stress the System Under Test (SUT) to it's maximum level.

Solver is connected directly to the MGW/MSC/VLRs, SGSNs, MMEs, and SGWs in the network, thus replacing the BSCs, RNCs, BTSs, Node Bs, and eNodeBs, enabling massive load and stress testing in the network.

Large volumes and heavy loads

Solver simulates, emulates and provides load generation in the access network against the core network and can thereby test systems and network elements such as SGSN/GGSN, MSC, MGW, MME and SGW.

Solver is capable of handling a large number of virtual subscribers, all of which can generate signalling and simulated payload data. The system has interfaces for both signalling and payload and includes protocol stacks according to 3GPP standards.
