摘要
pThe present invention provides an automatic frequency deviation correction method for a mobile terminal, comprising the step of configuring the mobile terminal with an initial frequency deviation value, which includes the following steps: when the mobile terminal initially accesses a cell, it synchronizes slots at intervals of a predetermined frequency deviation within a predetermined frequency deviation scanning range, and obtains the signal-to-interference ratio (SIR) of primary synchronization signal at the frequency deviation; after scanning the whole predetermined frequency deviation scanning range, the frequency deviation value corresponding to the maximum SIR of all the obtained SIRs as the initial frequency deviation value; and the mobile terminal is configured with the initial frequency deviation value to assure that the frequency deviation is controlled within the predetermined frequency deviation during the initial access. The present invention also provides an automatic frequency deviation correction system for a mobile terminal./p[EP2104293A1]
