Method, apparatus, mobile communication terminal, computer program and storage medium for adjusting frequency error of terminal
Handling a frequency error (FEQ) of a terminal which includes a plurality of modems using a same clock source includes: obtaining the FEQ, which is a difference between a carrier frequency of a received signal and a nominal frequency for each modem; obtaining a FEQ threshold of the received signal in a current service based on the FEQ; obtaining an adjusted value of the clock source corresponding to each modem based on the FEQ and the FEQ threshold; obtaining a synthesized adjusted value of the clock source based on the adjusted values of all the modems; and adjusting the frequency of the clock source based on the synthesized adjusted value of the clock source. The FEQ of the mobile communication terminal can be quickly corrected by adjusting the clock source's frequency, and, by considering the FEQ of all the modems, the modems' performances may be balanced.
