Problems solved by technology

[0005] When the cell-based positioning method is used in the mobile positioning system, when the mobile user is at the border of two or more cells, the positioning result information of several reported positions drifts between the reference positions of several adjacent cells, while Makes the positioning result information gap larger

Embodiment Construction

[0030] According to the planning information of the cell where the drift of the positioning result occurs, the present invention can have different solutions to the drift of the positioning result.

[0031] 1. If the cell coverage of the mobile user's location is different, resulting in positioning drift, select the cell with the largest current coverage as the positioning result, such as figure 2 shown;

[0032] 2. If there are two or more cells with overlapping coverage, such as image 3 As shown, the following positioning processing flow can be used to obtain the positioning result.

[0033] If the location result of the mobile user frequently switches between the geographical locations of the two cells within a period of time, that is, the mobile user frequently changes the selection between the reference cell between cell 1 and cell 2, so that the location result is the geographic coverage of cell 1 or cell 2 geographic coverage and changes frequently there. The metho...

Abstract

The invention relates to a method for solving the drift of positioning results during cell positioning. According to the planning information of the cell where the positioning result drifts, the following processing is performed: if there are two or more cells overlapping with each other, resulting in drift, when continuous When the two positioning results are another cell that overlaps with the originally reported cell, report the other cell as the positioning result; otherwise, continue to report the positioning result of the original cell. If the cell where the mobile user is located is covered by another cell, resulting in positioning drift, select the cell with the largest current coverage as the positioning result. The method of the invention can effectively suppress the phenomenon of positioning drift and improve the accuracy of positioning, especially for reporting when the service area changes, the amount of reported information can be effectively reduced, and for periodic reporting of positioning results, the drift of positioning results near time is avoided.

Description

technical field [0001] The invention relates to a cell-based positioning method of a mobile positioning system, in particular to a method for solving positioning result drift during cell positioning. Background technique [0002] Mobile positioning services in wireless network systems are receiving more and more attention. The main applications of mobile positioning services include: emergency call positioning services for user safety; location tracking of related criminal activities; personal positioning services (such as traffic, accommodation and other service industry information inquiries); intelligent transportation positioning; wireless network systems Design and resource management; used for wireless network system billing (determine the communication cost of certain locations according to the call rate). [0003] The cell-based positioning method is most commonly used in the mobile positioning system, and the positioning result of the mobile user is the coverage of...
