ABSTRACT:
The location of a remote unit (113) within a wireless communication system (100) is determined by all base stations (101) within the wireless communication system (100) initiating a first page (wide-area location page) that is broadcast to the remote unit (113) over a paging channel. The serving and neighbor base stations are determined from the remote unit's (113) response to the wide-area location page, and those base stations are instructed to tune receiving elements to obtain data that will be transmitted by the remote unit (113) during location. A second message (Location Page Message) is then broadcast to the remote unit (113) via the serving base station (101). The Location Page Message instructs the remote unit (113) to periodically transmit a known Remote Unit Location Message (RULM) with increasing power levels for a predetermined number of times so that the remote unit's (113) location can be achieved.
