Abstract

The invention discloses a wireless testing method and a wireless testing system for a GPS (Global Positioning System) of a mobile terminal. The wireless testing method comprises the following steps of: acquiring an average bottom noise value of the mobile terminal in advance; then acquiring an average SNR (Signal to Noise Ratio) value of the mobile terminal by carrying out OTA (Operational Transconductance Amplifier) testing in a hardware environment with low cost according to GPS NMEA (National Marine Electronics Association) log information acquired by testing and a rotating angle of the mobile terminal at each moment; and after carrying out calibration of the average bottom noise value, finally, obtaining the wireless sensitivity of the tested mobile terminal. According to the wireless testing method and system provided by the invention, the hardware testing environment with simple structure can be constructed by low investment and the wireless sensitivity of the mobile terminal is obtained by a series of steps so as to quantitatively estimate the receiving performance and the real using performance of the GPS of the mobile terminal.

Description

technical field [0001] The invention relates to the field of mobile terminal GPS testing, in particular to a mobile terminal GPS wireless testing method and system. Background technique [0002] Nowadays, more and more mobile phones have a GPS / AGPS (Assisted GPS, assisted GPS) function, and applications and services based on this function are also increasing. Therefore, mobile operators and equipment manufacturers are urgently looking for a test method that can quantify the real performance of mobile terminal GPS / AGPS. But until recently, the test method defined by 3GPP (the 3rd Generation Partnership Project) focused on the conduction performance of GPS / AGPS instead of the antenna. This test method that only focuses on conduction performance cannot be true. It reflects the performance of GPS / AGPS, because the GPS antenna of the mobile terminal will directly affect the GPS receiving performance of the mobile terminal when the GPS is in use. An ideal GPS / AGPS performance te...
