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

Abstract

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. The apparatus comprises a universal PC (Personal Computer), a radio frequency module and the tested terminal, wherein the universal PC comprises a TTCN-3 testing script and a system interface.Compared with the prior art, the invention has the advantages of comprehensive test, good universal performance, low cost, simplicity in deployment and the like.

Description

technical field [0001] The invention relates to the field of testing the air interface of a digital walkie-talkie, in particular to a method and a device for testing the air interface of a digital walkie-talkie based on TTCN-3. Background technique [0002] Digital walkie-talkies have many advantages. First of all, they can make better and efficient use of spectrum resources. Digital walkie-talkies can load more users on a designated channel and improve spectrum utilization. It is a solution to frequency congestion and has long-term significance. . The second is to improve the call quality. Since digital communication technology has a system action function, compared with analog walkie-talkies, it can achieve better voice quality in a wider range of signal environments, and the received audio noise will be less. clearer. Then it is to improve and improve the integration of voice and data, and change the weakness that the control signal decreases with the increase of distan...

Problems solved by technology

[0003] At present, the test methods for digital walkie-talkies are generally limited to the test of radio frequency indicators. If you want to achieve the comprehensive functional test required by the communication system, you need to customize a walkie-talkie comprehensive tester. The comprehensive test equipment has a long production cycle and is expensive. not universal
