Abstract
A system, method, and apparatus for determining a position of a mobile station in a mobile telecommunications network is disclosed. Speech interruptions during mobile station positioning are reduced or eliminated by controlling the number of access bursts transmitted by the mobile station. The number of access burst transmitted by the mobile station is controlled to a level commensurate with the degree of positioning accuracy required by the requesting application. The number of access bursts is calculated by the Mobile Location Center (MLC) and communicated to the Base Transceiver Station (BTS) via the Base Station Controller (BSC). After the requisite number of access bursts are received, the BTS transmits a signal to the mobile station, causing the mobile station to cease transmitting access bursts.
