Cellular radio system

摘要

A cellular radio system in which a base station (BS1) establishing two way communication with a mobile (10) requests base stations (BS2 to BS7) of a subset of adjacent cells to reserve a channel so that in the event of handover to a base station in one of these cells this can be executed quicker than if the reservation had not been made. In making the request for reservation, the communicating base station (BS1) passes on details of the call-in-progress. Once call has been handed over a new subset of adjacent cells is created.
