Title: Method of getting position tracking informations of mobile data terminals
Inventor: LEE HONG U
IPC: H04B7/26
Filed: 2002-09-11
Abstract: PURPOSE: A method for acquiring the location trace information of an MDT(Mobile Data Terminal) is provided so that an MDT, receiving a location trace request message from a location trace server, can acquire an SID(System Identification), an NID(Network Identification), a BID(Base Station Identification), and a PN(Pilot pseudo Noise) number for the present BTS(Base Transceiver Subsystem) and send a response message containing the acquired data as location trace state information. CONSTITUTION: If an MDT receives a location trace request message from a location trace server(S10), the MDT judges whether its own present mode is a slotted mode or a non-slotted mode(S11). If it is judged that the present mode is the slotted mode, the MDT transfers its own present mode to the non-slotted mode(S12). Then the MDT receives a location trace request message from the location trace server through a paging channel and acquires an SID, an NID, and a BID for the present BTS from the received message(S13). After acquiring the SID, the NID, and the BID, the MDT executes a finger program and acquires a PN number for the present BTS(S14). Then the MDT configures a response message containing the acquired data as location trace state information and sends it to the location trace server(S15).
