Mobile communication system performance test device, system and test method

Abstract

The invention discloses a performance testing device for a mobile communication system, a testing system comprising the testing device and a testing method. The testing device comprises a terminal interface module, a control module and a communication module, wherein, the terminal interface module is connected with one or a plurality of testing terminals; the testing terminals can access the mobile communication system; the communication module is connected with a remote server through a wireless network, and is used for downloading pre-determined testing scripts to the control module from the remote server; in addition, the control module controls the terminal interface module according to the testing scripts, and measures the wireless features of the mobile communication system through the testing terminals. According to the invention, the testing device can test in a completely automatic manner, so that a test is simple and convenient to implement, the process control is accurate, the result statistics is fast, and a great amount of resource investment needed by conventional testing manners can be saved.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for wireless performance of a mobile communication system, a system and a test method including the test device. Background technique [0002] The purpose of the wireless performance test of the mobile communication system is to verify the system performance in real scenarios. The test requires some users to be distributed in fixed positions in the system coverage area, while another part of users moves along the designated route within the area. All users conduct business according to the pre-designed call model. The user's deployment location, mobile route, and call model need to be as close as possible to the real situation when the network is running. During the test, the tester initiates a call through a manual operation terminal or notebook (used to control the wireless data terminal), and records the call success rate, service quality, call drop rate (disconnection rate) an...

Finally, although the drive test system or automatic drive test tool can automatically count some test results, it cannot output the results in the specified format according to the requirements of the test specification, and the link of unified analysis and processing by personnel is still indispensable.

[0006] Obviously, in the existing wireless performance testing methods of mobile communication systems, due to the lack of application of relevant automated testing devices, the following problems will inevitably exist. , an external power supply or even a test vehicle

Another example is that the randomness of the implementation process is difficult to control. In manual testing, all control operations are performed by testers, which is highly random and prone to operational errors; in semi-automatic testing, as long as there is an operational error or equipment problem at one test point, the entire The test process has to be stopped, and personnel can only communicate with each other to coordinate the synchronization and calibration between multiple test points

Another example is that the time control is inaccurate. Due to the manual operation of the testers, various reasons will cause the time of each test step to change short or long.

Even if the drive test system or automatic drive test tool is used to automatically dial, it needs to be manually activated by personnel, and the time is difficult to be accurate
