MOBILE COMMUNICATION SYSTEM

摘要

A mobile communication system in which mobile exchanges (6-8) having time division CDMA signals which share time slots and frequency channels with TDMA signals and a control function which assigns the signals to time axes and frequency axes are provided and mobile stations (15-33) are radio-connected with radio base stations (11-31) connected to the exchanges (6-8) in a multiple access system, and then, the mobile stations (15-33) having high speed data transmitting functions can be radio-connected to the radio base stations (11-31) even through high-speed channels. In this system, a serial number is given from mobile stations connected to two adjacent radio base stations to information in each time slot in the frame of each down line transmitted to one mobile station from these radio base stations and hand-over processing is performed based on the serial number.
