Embodiment Construction

[0028]The present invention aims at the problem that the mobile station cannot be passively located, and solves the problem that the mobile station cannot be passively located in the cellular network by establishing a mobile station main positioning mechanism, a global and local position update mechanism and a secondary positioning method, without modifying the mobile station and base station facilities Under certain conditions, the rapid positioning of the mobile station can be realized.

[0029] To achieve the above object, the technical scheme of the present invention is as follows:

[0030] Step 1, establish a mobile station master positioning mechanism. The corresponding sub-steps are: the corresponding sub-steps are: a. When the wireless terminal user (mobile station) is in a mobile state, it receives information from base stations within the coverage area, and then the wireless terminal sends a registration of the VVLR including the wireless terminal identification info...

Abstract

The invention provides a mobile station passive positioning method of cellular networks, which includes establishing a mobile station main positioning mechanism, an overall and local position update mechanism and an auxiliary positioning method to solve the problem that mobile stations cannot perform passive positioning in the cellular networks; and achieving the fast positioning of mobile stations without transforming mobile stations and base station facilities.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to mobile communication and wireless transmission. Background technique [0002] At present, the positioning of the mobile station in the wireless positioning system is by detecting the characteristic parameters (such as radio wave field strength, propagation time or time difference, incident angle, etc.) to estimate the geometric position of the mobile station. There are usually three kinds of positioning methods that can be used at present: dead reckoning, satellite positioning and terrestrial radio positioning. [0003] There are mainly two types of location service (LCS) functions for mobile users in the existing cellular systems. One is to use a mobile station-based positioning scheme or a GPS-assisted positioning scheme, which must be appropriately modified to the existing mobile station, adding the necessary Software and hardware devices, such as integrated G...
