GPRS (General Packet Radio Service) core network simulation and test system

The invention discloses a GPRS (General Packet Radio Service) core network simulation and test system applied to the field of mobile phone network testing. The system comprises a system access module, a system configuration and management module, a service test and management module, an alarm and management module and a fault analyzing and positioning module, wherein the system access module is accessed into a network through a simulated core network element and a hardware interface; and the service test and management module is used for issuing a test task, transferring a mobile phone simulated by the system configuration module to generate signaling and sending the signaling to the core network for testing through the simulated network element for testing. In the system, the simulated mobile phone and core equipment before an access point are used for testing, which crosses a wireless network and avoids the occupation to wireless network resources and the influence of the wireless network on a testing result. Meanwhile, in the method of the invention, a GPRS terminal quantity and a high-intensity test task are generated through software simulation, thus the system expansion cost is relatively lower.
