Problems solved by technology

[0004] In the MSA mode, the position is calculated on the platform side, so the computing resources on the platform side are consumed
The MSB positioning method has the advantages of high positioning accuracy and low pressure on the platform in outdoor applications such as oceans, but it cannot be positioned indoors without GPS satellites

Embodiment Construction

[0026] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0027] The basic idea of ​​an embodiment of the present invention is to implement MSB priority on the terminal, fall back to the positioning method of MSA, and realize the adaptive control method of MSB timeout according to the requirement of the scene through the controller.

[0028] figure 1 A flowchart showing an embodiment of the third-party positioning method of the present invention.

[0029] like figure 1 As shown, in step 102, the positioning terminal receives the positioning trigger information from the application platform, and initiates an MSB positioning request to the MPC (Mobile Postioning Center, Mobile Positioning Center);

[0030] In step 104, the positioning terminal interacts with MPC and PDE (Position Determining Entity, positioning entity) to calculate the MSB position;

Abstract

The invention discloses a third party positioning method and a terminal. The method comprises the following steps that: a terminal calculates through a MSB (Most Significant Bit) positioning mode, while being failed in positioning within timeout duration, returns back to a MSA positioning method for calculation. Moreover, the invention further provides a MSB positioning timeout duration adaptive adjustment method, the method comprises the following steps of: setting a timeout duration T controller, taking the positioning timeout duration and the positioning success of the MSB mode within a period of observation time S as the inputs of the controller, and then, executing adaptive control, thereby meeting the requirements of different scenes. The method and the terminal provided by the invention effectively improve precision of outdoor positioning, and can effectively reduce positioning delay and load on a positioning platform; and the adaptive adjustment time controller T can effectively satisfy the requirements of different scenes, and can solve the problem of positioning precision and positioning delay in different scenes.

Description

technical field [0001] The present invention relates to GPS (Global Positioning System, Global Positioning System) positioning technology, in particular to a third-party positioning method and terminal. Background technique [0002] A-GPS technology is a technology that combines base station information and GPS information to locate mobile terminals. This technology adds a GPS receiver module to the mobile phone, and at the same time builds a GPS reference network and its management platform. The GPS receiver of the GPS reference network The machine is used to receive GPS satellite signals in real time and transmit them to the GPS management platform through the network. The management platform transmits the information to the location service platform. Finally, the location service platform processes the information and transmits the processed information during the interaction process. Give mobile phones requesting positioning in the area covered by the reference station, ...
