Embodiment Construction

[0035] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0036] see figure 1 , a method for wireless positioning of a power-saving mobile terminal, comprising:

[0037] S1. Obtain real-time positioning information initiated by the mobile terminal, where the real-time positioning information includes positioning initiation time;

[0038] The mobile terminal uses its own GPRS communication and GPS functions to collect real-time positioning information of GPS and cellular network information, and report to the server.

[0039] The conditions for mobile terminal information acquisition and reporting are as follows:

[0040] 1) The reporting of mobile terminal information is carried out under the normal condition of GPRS network communication;

[0041] 2) The timing of obtaining and reporting base...

Abstract

The invention discloses a power-saving wireless positioning method for a mobile terminal. The power-saving wireless positioning method for the mobile terminal comprises the following steps of: acquiring real-time positioning information initiated by the mobile terminal; judging whether the difference between positioning initiation time and latest position time in a system is less than a preset value; setting the latest position corresponding to the latest position time in the system to be the physical position of the mobile terminal; and starting up a hardware GPS (Globe Positioning System), acquiring a GPS position coordinate, and setting the GPS position coordinate to be the physical position of the mobile terminal. The invention further discloses a power-saving wireless positioning device and a system for the mobile terminal. According to the power-saving wireless positioning method, the device and the system for the mobile terminal, disclosed by the embodiment of the invention, the mobile terminal decides the opportunity that the hardware GPS is started up to acquire the GPS coordinate according to a positioning strategy generated by a service end, so that not only are positioning accuracy and availability guaranteed, but also the power consumption of the mobile terminal is greatly reduced and the endurance capacity of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a method, device and system for wireless positioning of a power-saving mobile terminal. Background technique [0002] The mobile terminal positioning service is a positioning service based on the communication position in the wireless state. It can monitor and track all the controlled objects in real time, so that all the controlled objects are displayed on the electronic map of the monitoring center. Therefore, in the wireless mobile field It has wide application prospect. [0003] According to the WCDMA R99 specification, there are three positioning technical specifications followed by the wireless positioning solution: positioning technology based on Cell ID (cell identification), OTDOA positioning technology and network-assisted GPS positioning technology. Among the current wireless positioning schemes, Qualcomm's GPSONE positioning scheme is undoubtedly one of the most succe...
