Embodiment Construction

[0042] The existing positioning methods can refer to China Unicom's industry standard "800MHz CDMA Digital Cellular Mobile Communication Network V2 Positioning Service User Plane Related Equipment Technical Requirements", "CDMA 1X Digital Cellular Mobile Communication Network Mobile Station Specification", international standard "ANSITIA / EIA- IS-801Postion Deternimation Service Standard for Dual Mode Sperate SpectrumSystems》.

[0043] image 3 Provided is a schematic diagram of the process of realizing positioning entity switching under the trust mode of the present invention, and the specific description is as follows:

[0044] (S31) After the mobile station visits the access server of the home positioning entity, it sends related messages to interact with the positioning entity for measurement data between the base station and the satellite. The home location entity access server first checks whether it can perform location service for the mobile station to make a judgment....

Abstract

The method includes procedures: determining whether access server of home location entity (HLE) serves positioning mobile station (MS); based on information of measurement and calculation reported from MS, location entity determines whether it is needed to switch location entities; through information of the cell the MS is located on, the access server of HLE looks up the access server of the service location entity (SLE); the access server of HLE saves the access server of the service location entity, and forwards message, which is sent from the access server of the SLE to MS, to MS transparently; the access server of the SLE and the access server accomplish positioning calculation. The invention guarantees that location entity provides auxiliary information of base station in current location of MS as well as current location of MS is covered by referenced receiving device of location entity GPS satellite so as to raise switching positioning precision and success ratio.

Description

technical field [0001] The invention relates to a positioning method of a mobile communication network system, in particular to a method for realizing switching of a positioning entity in a trusted mode. Background technique [0002] Location Based Services (LBS for short), also known as mobile location services or positioning services, means that the mobile network obtains the geographic location information (latitude and longitude coordinates) of mobile terminals through specific positioning technologies, and provides them to mobile users themselves, communication System or a third party, with the support of certain electronic map information, provides mobile users with calling or non-calling services related to their location. [0003] The positioning methods of the mobile communication network include: cell-based positioning, positioning based on the traditional GPS (Global Positioning System, or Global Positioning System) system, and positioning based on Advanced Forwar...
