Abstract

This invention discloses a method of mobile positioning, including: A. the network side obtains the credibility of the measurement data form different base-station antennas in the station-sites. B. According to the results, it selects the data with the highest credibility and obtains the arrival angles of mobiles in different base stations according to the data. C. According to selected measurement data, the corresponding credibility and the obtained angles, it gets the mobile location information.

Description

technical field [0001] The invention relates to positioning technology, especially a method for positioning a mobile station (MS, Mobile Station) in a code division multiple access (CDMA) system. Background technique [0002] The positioning service is an important service in the wireless cellular communication system. In the CDMA system, the commonly used mobile station positioning methods include Assisted Global Positioning System (A-GPS) positioning, advanced forward link triangulation (AFLT), enhanced Type Forward Link Triangulation (EFLT), Cell ID (Cell ID), etc. These positioning methods actually refer to the measurement means of the data required for positioning. After obtaining the measurement data and other relevant information, appropriate The position information of the mobile station, such as latitude and longitude, altitude, moving speed and direction, can be obtained only by calculating with the positioning calculation method. The positioning calculation can b...
