Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] The embodiment of the invention discloses a method for positioning call information of a mobile user, so as to realize precise positioning of the call information of the mobile user. Positioning accuracy means that more than 70% of the sampling points are located within a square with a side length of 100 meters.

The invention discloses a method for positioning mobile subscriber call information, which comprises the following steps of: firstly, acquiring an MR data of the mobile subscriber call information; then selecting a cell coordinate as the center of a circle and a TA value in the MR as an external radius, subtracting the preset value from the TA value to serve as an internal radius, determining an annular area; sequentially computing according to information of six neighboring cells which is detected by the MR and reducing a positioned range, and selecting a positioned point in the annular area; and computing a coordinate of the position of the mobile subscriber call information relative to the positioned point according to the distance from the positioned point and the position of the mobile subscriber call information to the center of the circle in the annular area, and obtaining a positioned result of the mobile subscriber call information. The positioned result obtained by the method represents the specific position of the mobile subscriber call information relative to the positioned point, so that accurate positioning of the mobile subscriber call information is achieved.
Description
technical field [0001] The invention relates to the technical field of mobile communication, and more specifically, relates to a method for locating call information of a mobile user. Background technique [0002] In the field of mobile communication, in order to facilitate the realization of various technical applications based on user measurement reports, such as network planning, network optimization, etc. It is necessary to locate the geographical location of the call information of the mobile user at a certain time. Initially, when locating, only a certain cell where the mobile user’s call information is currently located can be determined, and the positioning accuracy is low, which cannot meet the requirements of service or monitoring and tracking. Therefore, more accurate positioning of the mobile user’s call information is required to meet the needs of network analysis applications. demand. [0003] There are two existing more accurate positioning methods, one is t...
