Embodiment Construction

[0047] The method for realizing positioning based on the mobile station of the present invention obtains the latitude and longitude by the terminal when realizing WAP positioning, and its processing process includes the following steps:

[0048] First, the terminal initiates a WAP-based positioning request, and the positioning service client requests the terminal for location information after receiving the request;

[0049] The terminal interacts with the Mobile Positioning Center (MPC) to complete the relevant authentication and authentication process;

[0050] The terminal interacts with the mobile positioning center to complete the calculation and acquisition of location information;

[0051] The mobile station sends the geographic location information of the mobile station to the positioning service client through the WAP service request message;

[0052] After obtaining the location information of the terminal, the LCS CLIENT provides services based on the location info...

Abstract

This invention discloses a method for realizing positioning based on a mobile station including the following steps: a mobile station starts a position request based on WAP, a positioning service customer processor receives the request and asks for position information to the terminal the mobile station starts the beginning of the positioning process request information, the mobile station and the mobile positioning center interact to finish authorization authentication and certification, the mobile station, positioning entity and mobile positioning center in interact to finish computation and acquirement of position information, the mobile station sends its position information to the position service customer processor, which provide service based on the position information to the mobile station.

Description

technical field [0001] The invention relates to a mobile positioning technology, in particular to a positioning method based on a mobile station. Background technique [0002] At present, the method for realizing positioning based on the mobile station through the WAP method includes the following steps: [0003] The user accesses the LCS CLIENT (location service client) through WAP, and sends a service request; [0004] LCSCLIENT sends a positioning request to the mobile positioning center (MPC) through the L1 interface, and starts the timer T4; [0005] LCSCLIENT returns a request response through WAP; [0006] The mobile positioning center sends an authentication message to the user / LCS CLIENT database to check whether the user who initiated the positioning and the LCSC CLIENT are authorized; [0007] The user / LCSCLIENT database returns the authentication result to the mobile positioning center; [0008] The MS initiates a positioning request StartPositioningProcessRe...
