Mobile terminal communication switchover field test method and system based on AT command

Abstract

The invention provides a mobile terminal communication switchover field test method and system based on an AT command. The method specifically comprises the steps that the AT command is transmitted to a mobile terminal which is connected with a serial interface through the serial interface, so that the mobile terminal launches corresponding call operation according to the received AT command; call status of the mobile terminal which is switched over from a first zone to a second zone within a preset call time is monitored in real time, and if it is detected that the call status is changed, the call status of the mobile terminal is judged to be off line; relevant abnormality information of the mobile terminal in a call off-line status is obtained, and the relevant abnormality information is output into a present Excel table automatically, so that the automatic recording for the mobile terminal communication switchover field test is achieved. By means of the method and system, the manpower is reduced, the mobile terminal communication switchover field test efficiency is raised, and meanwhile by means of the Excel table which records the abnormality information automatically, the subsequent automatic test analysis and tracing are facilitated.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and system for field testing of call switching of mobile terminals based on AT commands. Background technique [0002] With the development of mobile terminals (such as mobile phones, M2M modules), in order to verify the performance of mobile phones, each mobile phone and module manufacturers need to do a lot of Field Test (Call Test), that is, in various external use environments For example, use tests in various places such as residential areas, gathering areas of various high-rise buildings in cities, subway cars, buses, mountainous areas, and basements. Field tests usually involve functions that users use daily, such as Incoming and outgoing phone calls, sending and receiving short messages, browsing the web, etc. Taking telephone calls as an example, the test content is mainly to observe subjective evaluation indicators such as call completion rate...

AI Technical Summary

Problems solved by technology

[0003] That is to say, there are the following defects in the existing mobile phone call field test: manual test cannot accurately determine the time point when the problem occurs; it is not convenient for subsequent automated test analysis and tracking; it requires a lot of manpower, resulting in high cost and low efficiency of field test
