HAND-OVER METHOD IN CDMA MOBILE COMMUNICATION, BASE STATION AND MOBILE STATION

摘要

PROBLEM TO BE SOLVED: To relieve the processing load of a mobile station and to properly correct the phase of a frame by correcting the deviation of frame number at a base station thereby establishing synchronization after hand-over with respect to a hand-over method in a CDMA mobile communication system, the base station and the mobile station. SOLUTION: The mobile station MS measures a time differenceτbetween a frame timing of an incoming traffic channel and a frame timing of a perch channel from a base station BS2 of a moving destination, transmits the time differenceτto a base station BS1 during communication at present, and the base station BS1 informs the base station BS2 of the time differenceτand a frame number FN1 of an incoming traffic channel during the communication at present. The base station BS2 corrects a phase of a spread code in the case of receiving the incoming traffic channel based on the time differenceτbetween the informed frame timings and the frame number FN1.
