Abstract

A method to allow standard cellular handsets (121, 133) and personal data devices that support short-range communication to seamlessly connect to a wireless private branch exchange (WPBX) when it is in its coverage range. Thus the handset will become the handset of the WPBX, and there is no need to use special and expensive handsets with the WPBX. The WPBX includes a plurality of base stations (123, 124, 125), a plurality of switches (129), a plurality of gateways, all connected by communication links, and the required communication between them is also described. The operating procedures that the base stations and the switch perform are described. The WPBX allows handoff between cells, when a standard cordless handset is used. The handset does not support connection to more then one base station and does not support mobility. The handset uses complicated digital communication methods, so simple handoff methods that only the switch supports are not suffficient. The handoff operation requires cooperation of switch and base station and accurate synchronization of base stations.
