Patent ID: 8909181

Claim:
A method for implementing fast frequency sweeping of a mobile terminal, comprising: performing Received Signal Strength Indication (RSSI) measurements in communication frequency bands of a mobile terminal according to a preset first frequency sweeping step length, to obtain multiple first RSSI values; making decisions on the first RSSI values to obtain second RSSI values; sorting the second RSSI values; and performing frequency sweeping according to a sorted result, wherein the making decisions on the first RSSI values to obtain the second RSSI values comprises: multiplying a maximum value of the first RSSI values with a constant value, to obtain a decision threshold; comparing each of the first RSSI values with the decision threshold; reserving the first RSSI values larger than the decision threshold as the respective second RSSI values; and zeroing the first RSSI values smaller than or equal to the decision threshold forcibly.
