Embodiment Construction

[0031] Embodiments of the present invention provide a method, device, and system for determining the trajectory of a mobile terminal. The method selects at least one base station for each measurement information reported by the mobile terminal at a set time interval, and determines based on the measurement information. The primary common control physical channel (Primary Common Control Physical Channel, PCCPCH) of the base station receives the signal code power (Received Signal Code Power, RSCP) and timing advance, and determines the arrival of the mobile terminal according to the PCCPCH RSCP and timing advance of the base station The first distance and the second distance of the base station, according to the determined first distance and the second distance from the mobile terminal to each selected base station, determine the location information when the mobile terminal reports the measurement information, and determine the location information when the mobile terminal report...

Abstract

The invention discloses a method, a device and a system for determining the motion trail of a mobile terminal, and aims to solve the problems of low accuracy and long time delay in the motion trail determination of the mobile terminal in the prior art. The method comprises the following steps of: selecting at least one base station for each piece of received measurement information; determining the primary common control physical channel (PCCPCH) received signal code power (RSCP) and time advance of the base station according to the measurement information; determining the first and second distances of the mobile terminal to the base station according to the PCCPCH RSCP and the time advance, and determining the position of the mobile terminal when the mobile terminal reports the measurement information according to the first and second distances; and determining the motion trail according to the position of the mobile terminal when the mobile terminal reports each piece of measurement information. According to the embodiment of the invention, the motion trail of the mobile terminal is determined according to the PCCPCH RSCP and the time advance in each piece of measurement information, so that the motion trail determination accuracy of the mobile terminal is improved, and the motion trail determination time delay of the mobile terminal is shortened.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and system for determining the motion trajectory of a mobile terminal. Background technique [0002] With the continuous maturity and development of the third generation communication technology (3rd Generation, 3G), users' demand for positioning services is increasing day by day. Wherein, the positioning of the mobile terminal includes: single-point positioning of the mobile terminal, and determination of the moving track of the mobile terminal. [0003] In the prior art, the method for determining the trajectory of the mobile terminal mainly includes: a method for determining the trajectory based on the network cell identification (CELL-ID), and a method for determining the trajectory based on the Global Positioning System (Global Positioning System, GPS). method. [0004] The method for determining the movement trajectory based on the network CELL...
