Positioning method, device, computer equipment and medium based on MSC GT code
Technical Field
The present invention relates to the field of mobile positioning technologies, and in particular, to a method, an apparatus, a computer device, and a medium for positioning based on an MSC GT code.
Background
In WCDMA systems, there are three main mobile positioning techniques, including CELLID (cell identification) -based positioning techniques, OTDOA (Observed Time Difference Of Arrival) positioning techniques, and network assisted GPS positioning techniques.
The positioning technology based on CELLID is a most basic positioning method, and is based on the position of the base station where the mobile user is currently located and the coverage of the cell, and the position of the mobile user is within a circle with the base station as the center and the coverage radius of the cell as the radius or within the sector range of the cell. Obviously, the accuracy of this positioning method depends on the cell size, and the larger the cell coverage, the worse the positioning accuracy.
The OTDOA positioning technique is that a mobile subscriber measures downlink pilot signals of different base stations to obtain TOA (Time of Arrival), and uses a position estimation algorithm to obtain the position of the mobile subscriber according to the measurement result in combination with the coordinates of the base stations. The scheme needs a plurality of base stations, has high complexity and needs the terminal to be matched and realized.
Network Assisted GPS (a-GPS) positioning technology requires a network side to send GPS information to a mobile user, and the mobile user starts measurement and feeds back the measurement result to a positioning module, and the positioning module calculates the current Position of the mobile station. The scheme requires interaction between a network side positioning module and a mobile user, so that the positioning time is long, the mobile user cannot be positioned at a place with a weak GPS signal, and certain limitation is realized.
