System and method for testing cell-phone radio-frequency signal

Abstract

The testing system thereof comprises: a simulation base station for transmitting a specific frequency signal, and running a specific testing program to test the RF signal transceiver performance of mobile phone. The simulation base station is connected to a computer which controls the running of the simulation base station, is connected to the mobile station to be tested, controls and simulates the signal transmission between the simulation base station and the mobile phone to be tested.

Description

【Technical field】 [0001] The present invention relates to a test system and test method for mobile phone radio frequency signals, in particular to a test system that uses a computer device to control a mobile phone to respond to a simulated base station, and to feed back to the simulated base station in time, thereby avoiding manual operation and improving test efficiency. and reduce production costs. 【Background technique】 [0002] In the production process of mobile phones, in order to ensure the ability of mobile phones to receive and transmit signals, most system assembly plants install an analog base station (the industry mostly uses wireless integrated testers to realize), and put the mobile phone in a shielding box to To prevent interference from other signals, during the test, the simulated base station first searches for the mobile phone's transmission signal, and then the simulated base station runs a predetermined test program to test the mobile phone's signal thr...

Problems solved by technology

[0002] In the production process of mobile phones, in order to ensure the ability of mobile phones to receive and transmit signals, most system assembly plants install an analog base station (most of the industry uses wireless integrated testers to realize), and put the mobile phone in a shielding box to To prevent interference from other signals, during the test, the simulated base station first searches for the mobile phone's transmission signal, and then the simulated base station runs a predetermined test program to test the mobile phone's signal through the signal transmission and feedback between the mobile phone and the simulated base station. The performance of signal sending and receiving circuits can only be tested after the mobile phone enters the system in the above process, which leads to a long waiting time (especially for high-end mobile phones with complex operating systems, such as Smart Phone or PDA Phone), such as For three-band mobile phones, when the frequency band is switched to 1900MHz, it is necessary to open the shielding box and reconnect the phone once, which makes the whole test complicated and inefficient

What's more, for the current popular smart phones in the market, because they have a touch screen, it is necessary to calibrate the screen when starting up, and then search for signals. This takes about 75 seconds, and during the test process from 900MHz or 1800MHz When the frequency band is switched to the 1900MHz frequency band, it takes about 30 seconds for the signal switching process, and the call needs to be connected again, which is more time-consuming, which is not conducive to reducing production costs
