Title:
CELL SELECTING METHOD, BASE STATION DEVICE AND MOBILE STATION DEVICE IN CDMA MOBILE COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3233854
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cell selecting method, a base station device and a mobile station device in a CDMA(code division multiple access) mobile communication system which shortens a cell selective processing time and also can construct a mobile communication system that has base station structural realizability.
SOLUTION: A base station which has a GPS antenna 10 and a GPS receiving part 11 and can generate the same reference timing in plural base stations shortens cell selective processing in a mobile station by using the same diffusion code with each base station in a different diffusion code phase for the diffusion processing of a pilot channel. On the other hand, a base station which does not have the antenna 10 or the part 11 and is difficult to have the same reference timing can construct a mobile communication system that has realizability without increasing the scale of a hardware by allocating a different diffusion code to each base station for the diffusion processing of a pilot channel.
