Problems solved by technology

However, in the actual system operation process, there are often situations where the base station information is incomplete, especially the location information of the newly added base station cannot be loaded into the mobile positioning system in a timely manner.
[0004] If the mobile positioning system obtains the serving cell of the mobile terminal, but cannot find the location information of the base station of this cell in the base station information, the positioning calculation cannot continue, and the position of the mobile terminal cannot be determined, and this positioning is unsuccessful.
It can be seen that the lack of base station location information will affect the success rate of mobile terminal positioning

Embodiment Construction

[0023] For the convenience of expression, in the present invention, base stations without location information or whose location information should be updated but not updated are referred to as location-unknown base stations, and base stations with location information that do not need to be updated or have been updated are referred to as location-known base stations.

[0024] The invention provides a method for improving the success rate of base station positioning. When the mobile positioning system loads base station information, it loads the location information of the base station and the list of neighboring cell base stations of the base station. The so-called list of neighboring cell base stations refers to the target base station to be loaded. The list of adjacent base stations. For any base station whose location is unknown, use the location information of the neighboring base stations in its neighbor base station list to estimate its location information, and use the e...

Abstract

The invention relates to a method for improving base station location success rate. By means of the method, location information of a base station and a list of neighbor base stations are loaded when a mobile locating system loads base station information, for any base station with unknown location, the location information of the base station is estimated through location information of neighbor base stations in the neighbor base station list, the estimated location information is used in location calculation of the mobile locating system, the neighbor base station list for estimating the location information of the base station with unknown location is composed of part of or all of base stations with known location of the neighbor base stations of the base station with the unknown location, and the estimation method can be a centroid method, an outer center method and the like. In addition, direction information and / or height information of the neighbor base stations can be loaded for further improving the estimation accuracy, and requirements for high location accuracy can be met. By means of the method, the location of the base station can be estimated through the location information of the neighbor base stations under the condition that the location information of the base station is not timely loaded or updated, and accordingly the success rate of mobile location can be effectively improved.

Description

technical field [0001] The invention relates to a method for improving the positioning success rate of a mobile terminal by a mobile communication network by estimating the position of a base station whose position is unknown in the mobile communication network. Background technique [0002] In the mobile communication network, various methods can be used to locate the mobile terminal, and among the various positioning methods, the location information of the base station is the most important basic data. Whether the location information of the base station is comprehensive and accurate determines the success rate and accuracy of positioning the mobile terminal. [0003] In the mobile positioning system, the location information of the base station is configured and loaded by the system administrator. Because the mobile communication network often optimizes and adjusts the base station, the information of the base station often changes. After the information of the base sta...
