Description

Automatic test method for mobile phone communication and automatic caller for mobile phone

technical field

The invention relates to a mobile communication terminal, in particular to an automatic testing device and method for a mobile communication terminal.

Background technique

The mobile terminal and the base station in the mobile phone network (GSM, PCS, CDMA, etc.) communicate through the wireless environment, and the wireless environment is generally affected by uncertainties such as weather, external electromagnetic interference, signal propagation path, and man-made. Therefore, the test results are based on a large amount of statistical data. In this regard, it is often necessary for testers to make hundreds of consecutive calls and record the connection time. The task is very boring and heavy; and due to human factors, it is often impossible to directly locate the problem when an exception occurs. Therefore, it is necessary to Automated methods are introduced to replace this manual, mechanical, repetitive work.

At present, there are several options for adopting the automatic analog call system:

The first solution is to use the instrument of the test instrument manufacturer, use the general interface bus (GPIB interface) to control, use the test instrument to simulate the terminal (or base station), and the base station (or mobile terminal) to be tested directly communicates with the The test instrument is connected, and the communication test is carried out through the software module of the test instrument. This scheme can realize the function of automatic calling through the test module developed by the test instrument manufacturer, but its disadvantages are large investment (need to purchase test instrument and test software module), and there are differences from the real environment. The second solution is to modify the program on the base station controller (CSC), simulate the caller through the equipment on the network side, and directly initiate a call to the mobile terminal, while the real mobile phone is used as the called party to communicate. The advantage of this method is that it requires less investment and the communication environment is real, and it can be realized only by modifying the corresponding software in the network test. It can only ring, and cannot complete complete signaling such as follow-up calls and hang-up. The third solution is to use the interface of the mobile terminal to monitor the status signaling of the mobile phone through the data line to control the communication between the mobile phone and the base station. This method is simple and convenient, requires less investment, and has a real communication environment. Its disadvantage is that it needs the cooperation of the mobile terminal manufacturer to provide the control command set of the interface, which is limited by the model of the mobile phone.
