Abstract
A subscriber (510) to a radio communication system acquires new neighbor cell information after switching to a new server site (530) during lulls in an ongoing communication session. In one embodiment, the new server site (530) broadcasts neighbor cell list information during lulls in the communication activity on the communication channel in an unsolicited manner (710, 720). In an alternative embodiment, the subscriber (510) first transmits a request to the server site for neighbor cell list information during a lull in communication activity (810, 820). The server site (530) responds by transmitting neighbor cell list information during one or more lulls in communication activity on the communication channel (830, 840).
