Method, system and apparatus for testing performance of mobile communication system

The invention relates to a mobile communication technique, in particular to a method, a system and a device for testing the performance of a mobile communication system, which is used for solving the problem existing in prior art that when carrying out a test on the switching performance of the mobile communication system, as a variable attenuator needs to be manually regulated, testing personnelhave to carry out massive repeated operation, which results in reducing testing efficiency and testing accuracy. The method for testing the performance of the mobile communication system comprises that: the attenuation value of a source district signal and a target district signal received simultaneously by a user device is determined, at least twice; according to the attenuation value being determined, a parametric script is generated; the parametric script is executed so as to generate a control command, and the control command is sent to the variable attenuator. By adopting the mobile communication technique of the invention, the testing personnel can avoid massive repeated operation, thus improving the testing efficiency and the testing accuracy.
