Abstract:
A method for locating a mobile station (MS) based on a power-related message of base transceiver stations (BTS) in a mobile communication system, comprising the steps of:a) by a call control processor (CCP) of a base station controller (BSC), checking an active set that the mobile station currently holds; b) by the call control processor, determining if the active set is covered over three base transceiver stations; c) if the active set is not covered over the three base transceiver stations, by frequency allocation of the active set, reading out status information of neighboring base transceiver stations; d) by the call control processor, determining if the frequency allocation of the active set is usable; e) if the frequency allocation is usable, transmitting to the mobile station a PSMRO (pilot strength message request order) that is a message for requesting to measure pilot strength of the frequency allocation; f) arranging a plurality of base transceiver stations in order of pilot strength based on a pilot strength measurement result and selecting 3 base transceiver stations having higher pilot strength; and g) directing the selected 3 base transceiver stations to be prepared to receive a PUF (PUF=power up function) pulse.
