Abstract

The invention provides a multi-site positioning method and device, relates to the technical field of communication, and is used for solving the problem of insufficient positioning precision caused byRTT measurement in a positioning architecture taking a positioning management function as a center. According to the method, the above problem is solved, RTT positioning is carried out through cooperation of multiple base stations, and the positioning precision is improved. The method comprises the following steps: target equipment receives positioning auxiliary information sent by a positioning center, wherein the positioning auxiliary information comprises cell identifiers and reference signal configurations of a service base station and at least one neighbor base station; the target equipment performs positioning measurement on the downlink reference signal according to the positioning auxiliary information; the target equipment sends an uplink reference to the serving base station andthe at least one neighbor base station according to the positioning auxiliary information; and the target equipment sends a downlink positioning measurement report to the positioning center, wherein the downlink positioning measurement report comprises the receiving and sending time difference of the reference signals corresponding to the service base station and the at least one neighbor base station measured by the target equipment.

Description

technical field [0001] The invention relates to the field of positioning in a wireless communication system, in particular to a multi-site positioning method and device. Background technique [0002] With the continuous development of communication technologies, communication between terminals and network nodes has become a common communication between devices. It is more and more important for a network node to locate a terminal, or for a terminal to request a location service to implement a specific application. Generally, in an open outdoor scene, using a global positioning system (GPS) for positioning can already meet a relatively satisfactory positioning accuracy requirement of tens of meters. However, in indoor or in complex urban areas, the current positioning effect of GPS is not ideal. At this time, it is necessary to obtain more line-of-sight by deploying stations indoors or in urban areas to achieve better positioning results than GPS . With the development of ...
