Method and apparatus for testing air interface of TTCN (Testing and Test Control Notation)-3-based digital interphone

The invention relates to a method and apparatus for testing an air interface of a TTCN (Testing and Test Control Notation)-3-based digital interphone. The method comprises the steps of: (1) initializing: starting a main control module and creating two parallel testing modules, i.e., a terminal simulating module and a tested terminal setting module; (2) respectively operating the two parallel testing modules: firstly, conducting handshake communication with the main control module to enable the main control module to master the operating modes of the two parallel testing modules in time, judging whether the two parallel testing modules have abnormality or not, and executing step (3) if both of the two parallel testing modules are normal, ending the test if the two parallel testing modules are abnormal; and (3) controlling a tested terminal through the tested terminal setting module to set parameters or conducting the step of setting the parameters and the like directly on the tested terminal.
