Abstract

The method for reducing status reporting in a wireless communication system (100), such as a code division multiple access wireless communication system is described. Wireless communication system (100) includes a mobile switching center (202), a base station controller (204), and a plurality of base transceiver stations (240-242). The method includes wireless communication system (100) receiving a mobile communication signal (115) from a mobile station (220), and based on the mobile communication signal (115), invoking delivery of an information element (230) to base station controller (204). The method further includes, based on information element (230), selectively forwarding by base station controller (204) a status message to mobile switching center (202). In addition, the method includes acknowledging, by base station controller (204), successful receipt of information element (230).

Claims

1. In a wireless communication system, said system including a mobile switching center, a base station controller, and a plurality of base transceiver stations, a method for reducing status reporting to said mobile switching center comprising:

receiving from a mobile station, a mobile communication signal;

based on the mobile communication signal, invoking delivery of location information to said base station controller; and

based on said location information and a location reporting parameter, said base station controller selectively forwarding location information from said base station controller to said mobile switching center only when said base station controller detects a location change for the mobile station, wherein the location reporting parameter comprises a bit map which is arranged to define a specific condition that causes status messages to be forwarded.

2. The method according to claim 1, further comprising the step of forwarding an Assignment Complete message from said base station controller to said mobile switching center.

3. The method according to claim 2, wherein said Assignment Complete message comprises a information element acknowledgment, said information element acknowledgment confirming receipt of said information element by said base station controller to said mobile switching center.

4. In a wireless communication system, said system including a mobile switching center, a first base site including a first base station controller with an associated plurality of base transceiver stations, a second base site including a second base station controller with an associated plurality of base transceiver stations, a method for reducing status reporting to said mobile switching center comprising:

receiving from a mobile station, a mobile communication signal;

assigning, by said first base station controller, said mobile communication signal, to one of said associated plurality of base transceiver stations;

reassigning by said mobile switching center, said mobile communication signal, to one of said associated plurality of base transceiver stations associated with said second base station controller;

based on said mobile communication signal reassignment, invoking delivery of a mobile station location to said second base station controller;

based on said mobile station location and a location reporting parameter, said second base station controller selectively forwarding a status message from said second base station controller to said mobile switching center only when said second base station controller detects a location change of said mobile station from a first coverage area to a second coverage area, wherein the location reporting parameter comprises a bit map which is arranged to define a specific condition that causes status messages to be forwarded; and

acknowledging, by said second base station controller, successful receipt of said information element.
