Abstract

A handoff method and apparatus are disclosed for use in a wireless communication network in which a base station servicing a call selects a handoffcandidate base station based in part on subscriber-specific information. For example, in some wireless networks, certain subscribers can only access a limited number of base stations and the subscriber-specific information identifies such access limitations. A central control processor provides the subscriber-specificinformation to the base station servicing the call during the course of the call. The base station is then operable to select a handoff candidate from the one or moreneighbor base stations based on one or more neighbor base station signal qualitymeasurements and subscriber-specific information.
