A method for testing total isotropic sensitivity (TIS) of a mobile terminal is provided in the present invention, which includes: acquiring a function relation curve of input power PInAnt of antenna port and bit error rate (BER) for a channel to be tested: BER = f(PInAnt ), or PInAnt = f -1(BER); according to said function relation curve of the input power of the antenna port and BER, performing f and ? polarization tests to obtain the effective isotropic sensitivity EIS ? ( ? i , f j ) and EIS f ( ? i , f j ) at a space position (? i , f j ); after testing the EIS ? ( ? i , f j ) and EIS f ( ? i , f j ) at all space positions, calculating to obtain the TIS for said channel to be tested. According to the emibodiments of the present invention, on the premise that the test precision is not lost, the TIS test speed can be effectively improved, and the fast and accurate TIS test can be realized.
