Title:
移動体通信システムにおける移動局の基地局との周波数同期のための方法及び装置
Document Type and Number:
Japanese Patent JP4607108
Kind Code:
B2
Abstract:
In a method for synchronizing a mobile station with the base station in a mobile communication system, a reference-frequency oscillator is re-adjusted. To enable an inexpensive reference-frequency oscillator of simple construction to be used, the frequency variations resulting from a change in the temperature of the mobile station and a change in its location are determined and/or predicted separately. When the frequency variations are large, the mobile station is synchronized with the base station more frequently than when they are small.
