Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0031] Functional Overview

[0032] Considering that the positioning method of the mobile terminal in the related art will cause the problems of low accuracy and large error, the present invention provides a positioning method and system of a mobile terminal. In the solution of the present invention, the mobile positioning center sends a GPS positioning request message to the mobile station through the PDS or MSC, so that the mobile station performs GPS positioning. Compared with the wireless measurement positioning method in the prior art, the position information obtained by the GPS positioning method in the present invention has higher accuracy. In addition, since the time required for ...

Abstract

The invention discloses a mobile terminal positioning method and system. The method comprises that a mobile positioning center sends a GPS positioning request message to a mobile station through a mobile exchange center or a PTT scheduling server, so as to enable the mobile station to GPS positioning according to the GPS positioning request message; the mobile positioning center receives positioninformation of the mobile station forwarded by the mobile exchange center or the PTT scheduling server, wherein the position information of the mobile station is obtained through GPS positioning. Position information obtained through using the GPS positioning has higher precision, since the time required for GPS positioning is less than the time required for wireless measurement, the time requiredfor positioning is shortened.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a positioning method and system for a mobile terminal. Background technique [0002] Location Based Services (LBS), also known as mobile location services or positioning services, means that the mobile network obtains the geographic location information (longitude and latitude coordinates) of the mobile terminal through a specific positioning technology, and provides it to the mobile user and communication The system or a third party, with the support of certain electronic map information, provides mobile users with call or non-call services related to their location. [0003] Trunking communication is a communication method developed on the basis of mobile communication technology. It belongs to the category of mobile communication. Its main feature is PTT (Push To Talk, that is, you can talk with one press). In other words, the call is established directly, and the group use...
