Abstract

A mobile radio communication system including at least one exchange, a network including a plurality of base stations, and a mobile station communicating simultaneously with the plurality of base stations, in which the transmission delay between the local station and the base stations varies in response to a plurality of service types that can be provided to the mobile station. It is the objective of the technique that communication with an appropriate transmission delay in response to the service type is to be enabled, and synchronization is to be recovered even when pull out occurs. Therefore, a storage member (processor (32) in local station) for storing the transmission delay for each service type in response to the plurality of service types that can be provided to the mobile station is provided. In addition, a setting member (diversity hand-over trunk (34) for setting the communication timing at each of the base stations on the basis of the transmission delay corresponding to the service type applied to the mobile station is provided.
