摘要

A mobile communications system allowing high-speed setup and release of connection is disclosed. A primary group of base stations and a secondary group included in the primary group are set and a base station included in the secondary group is connected to a mobile station by a corresponding individual wireless link. Further, two common control channels PCCCH and SCCCH are provided to transfer control information and the PCCCH has a shorter control period. The setup control is performed only for a limited number of individual wireless links between the mobile station and the secondary group of base stations.
