Abstract
In a cellular communication system, a plurality of neighbor scan lists are generated and associated with a selected cell in the cellular communication system, wherein each neighbor scan list includes selected neighbor identifiers. Thereafter, a present operating mode, of a plurality of operating modes, of a subscriber unit communicating with the selected cell is determined. In response to the present operating mode of the subscriber unit, the subscriber unit is configured to scan a neighbor scan list selected from the plurality of neighbor scan lists for the selected cell. The operating modes of the subscriber unit may include an idle mode and an active mode.
Claims18
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;
- and
- prior 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.
A system in a cellular communication system for controlling neighbor scanning in a subscriber unit comprising:
- means for 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;
- means for determining a present operating mode of a plurality of operating modes of a subscriber unit communicating with the selected cell;
- means for configuring the subscriber unit to scan a neighbor scan list selected from the plurality of neighbor scan lists for the selected cell, in response to the present operating mode of the subscriber unit;
- and
- means for communicating to the subscriber unit, prior to detecting an operating mode change in the subscriber unit from the idle mode to the active mode, the scan list associated with the idle mode and the scan list associated with the active mode.
