Method of processing a call while switching site affiliation in a radio communication system

摘要

A subscriber unit handles incoming calls routed through an old server site while in the process of switching site affiliation to a new server site (500). The subscriber unit initiates the switching of site affiliation (510), and during the process, alternates between receiving communication from the new server site (520) and receiving communication from the old server site to monitor for an incoming call (530). When an incoming call routed through the old server site is detected (540), the subscriber unit aborts or suspends the switching process and accepts the incoming call through the old server site (551, 552).
