Embodiment Construction

[0028] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0029] attached figure 1 The positioning service network structure includes mobile terminal (mobile phone), wireless access network, mobile exchange (MSCNLR), gateway positioning center, home location register, and positioning service client. The general positioning process is that the positioning center of the mobile gateway interacts with the home location register of the positioned mobile terminal to obtain the status of the currently positioned mobile terminal and the address of the mobile switching center to which it roams. Then the mobile gateway positioning center interacts with the roaming MSCNLR or positioning entity, and the roaming MSCNLR or positioning entity performs the final specific positioning process, and then returns the positioning result to the mobile gateway positioning center.

Abstract

A method for realizing cross - bureau positioning service in PHS system includes sending request of positioning to gateway positioning centre by positioning service client computer ( PSCC ) and then sending it to switch by said centre, send route request message of positioning service to attribution position register ( APR ) by switch, send message providing user information of positioning service to calling switch of positioned user by APR, returning response message of user information to APR, returning response message of route request to switch initialized positioning, returning the positioning result to gateway positioning centre then returning position of position user to PSCC.

Description

technical field [0001] The invention relates to a method for realizing cross-office positioning service in a PHS system (personal hand-held system). Background technique [0002] The positioning service refers to obtaining the location of a mobile terminal through wireless positioning technology in a mobile communication system, and providing corresponding services based on the location of the mobile terminal. The main application areas of positioning services include: public safety emergency calls, value-added services, etc. [0003] In the mobile communication system, there are specifications that define and describe the functional mode, system structure, and message flow of the positioning system. In addition to the traditional network entities in the mobile network, the positioning system also includes newly added network entities. The former includes mobile terminal, mobile switching center and home location register, and the latter includes mobile gateway positioning...
