Abstract:
A method in a cellular communication system for controlling neighbor scanning in a subscriber unit, the method comprising the steps of:generating a plurality of neighbor scan lists associated with a selected cell in the cellular communication system, including a neighbor scan list associated with an idle mode and a neighbor scan list associated with an active mode, wherein each neighbor scan list includes selected neighbor identifiers;determining a present operating mode of a plurality of operating modes of a subscriber unit communicating with the selected cell;in response to the present operating mode of the subscriber unit, configuring the subscriber unit to scan a neighbor scan list selected from the plurality of neighbor scan lists for the selected cell; andprior to detecting an operating mode change in the subscriber unit from the idle mode to the active mode, communicating to the subscriber unit the scan list associated with the idle mode and the scan list associated with the active mode.
