Methods tetra digital trunking air interface protocol testing and systems

The present invention provides a method and system for digital trunked TETRA air interface protocol for testing. The system comprising: a test system, comprising a main TETRA digital test mobile terminal and a network device, a mobile terminal connected through a PEI test system, receives and executes the control command transmitted by the test system, aerial wireless communication network with a network device signaling interaction interface; a test system, load and execute test cases, test cases corresponding to the transmission control command to the mobile terminal by PEI, to a predetermined air interface signaling monitoring and digital trunked TETRA air interface standard protocol signaling protocol stack matching comparison, authentication interoperability between TETRA digital trunking main test mobile terminal and a network device. The present invention may be used between the TETRA digital automatic test terminal and a network device air interface protocol interoperability, for TETRA air interface protocol between the terminal and the digital trunking network test equipment interoperability.
