Abstract
A method and corresponding system for management of neighbor scanning in a cellular wireless communication system is disclosed. A radio access network (RAN) sends, and a mobile device receives, a neighbor list update message containing a plurality of different neighbor lists each listing available neighboring coverage areas communicating on respective communication channels. While the mobile device is engaged in a call, the mobile device selects one of the neighbor lists based on a service type of the engaged call. The mobile device scans the neighbors listed in the selected neighbor list for signal strengths sufficient to trigger a hand off. The mobile device sends a report indicating measured signal strengths of signals from the neighbors to the RAN, which then instructs the mobile device to hand off the engaged call.
