Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] In the calculation process of the sector optimization method of the present invention, some parameters of the base station must be used each time, such as base station latitude Cell_LAT, base station longitude Cell_LONG, sector start angle α, sector end angle β, base station outer radius R, etc. In the location service platform system, a base station sector information table for storing base station parameters can be additionally established and maintained. Due to the large number of base stations and frequent changes, in order to facilitate the management, operation and maintenance of base station parameters by network operators, the system can provide a friendly web-based interface to provide management methods and maintenance functions for...

Abstract

The invention consists of IP interface message processor, signaling system 7 interface message processor, geo information server, location service logical server and operation maintaining machine. The system supports 2G, 2.5G, 3G mobile communication network, and supports opening interface for third party. It accords with GMLC criteria in 3GPP. The invention also provides a sector optimize method used in locating service: the geometric center point in sector where mobile terminal locates replaces the location of base station in center of cell, and is taken as current location of the mobile terminal.

Description

technical field [0001] The present invention relates to a location service platform integrating positioning and business functions, and a sector optimization method used in the positioning process, to be precise, relates to a method used in 2G, 2.5G, or 3G mobile communication networks The invention provides a work platform system based on location services and a sector optimization method for improving positioning accuracy; it belongs to the technical field of mobile positioning devices in telecommunication networks. Background technique [0002] Location Services (LCS, Location Services) or positioning service in mobile communication network is a value-added service that obtains the location information (for example: its latitude and longitude) of the user's mobile terminal through the mobile communication network, and then provides corresponding services. In recent years, due to its excellent functions in emergency rescue, positioning of relatives and friends, car navigat...
