Use of immediate handover to achieve multi-head zones

摘要

A wireless handset does not perform a re-registration operation when its serving base station is at capacity, and a wireless controller controlling a wireless switching system is allowed to send incoming calls for the wireless handset to the base station even if the base station is at capacity. The base station signals a new call to the wireless even if the base station is at its active call capacity. The wireless handset is responsive to the incoming call to perform a base station re-direct operation to a new base station that has idle call capacity, and the call setup is completed to the wireless handset via the new base station. The base station re-direct operation is a new wireless operation. The base station re-direct operation is controlled by the system wireless controller in a second embodiment.
