Abstract:
1. A method for providing the location information of a mobile station (MS) by selectively using a data burst message (DBM)-based method and a TCP/IP (Transmission Control Protocol/Internet Protocol)-based method based on a global positioning system (GPS) in a mobile telecommunication network, constituted of a client server, a mobile positioning center (MPC), a home location register (HLR), and a position determination Entity (PDE), comprising the steps of: a terminal connecting to a client server for being provided a location based service (LBS); said client server carrying out an authentication and selecting one of a DBM-based method and a TCP/IP-based method, wherein said MS communicates said location information of said MS with said PDE via data burst messages in said DBM-based method, wherein said MS communicates said location information of said MS with said PDE via a TCP/IP network in said TCP/IP-based method; in case of a TCP/IP-based method being selected, said client server transmitting a PDE URL to MS, and then sending an information by a signal to MPC; and in case of a DBM-based method being selected, said client server sending an information by a signal to MPC; said MPC transmitting a request signal for the information of said MS to HL and receiving the response; after receiving said response, said MPC transmitting a signal, containing the corresponding information, to PDE; said PDE obtaining the location information of said MS from said MS by the selected type of method; and said PDE transmitting the obtained location information of said MS to said client server through said MPC; wherein said step of selecting one of said DBM-based method and said TCP/IP-based method includes said client server selecting said TCP/IP-based method if said terminal connected to said client server is identical to said MS whose location information is to be provided, and otherwise, said client server selecting said DBM-based method; and wherein said corresponding information, contained in said signal being transmitted from said MPC to said PDE after said MPC receiving said response from said HLR, contains the information on the type of method selected by said client server and the information on the mobile switching center(MSC) controlling said MS.
