Problems solved by technology

However, when the cell identity of the serving cell of the UE corresponds to multiple specific access locations of the UE that are far apart, for example, in the case of remote radio frequency, the positioning center may not be able to select a suitable reference cell only based on the cell identity of the serving cell of the UE. As a result, it is impossible to locate the UE

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] An embodiment of the present invention provides a positioning method, wherein, if the serving cell of the UE corresponds to at least two radio frequency units, the positioning center obtains the information of the current access point location of the UE, and according to the location of the current access point of the UE The information selects the reference area. The positioning center sends the information of the reference cell to the UE, and receives...

Abstract

The embodiment of the invention provides a positioning method and device, wherein the positioning method comprises the steps that: if a service cell of UE (User Equipment) corresponds to at least two radio frequency units, a positioning center obtains position information of a current access point of the UE, and selects a reference cell according to the position information of the current access point of the UE; and the positioning center sends information of the reference cell to the UE, and receives a measurement result of the UE aiming at the reference cell. In the embodiment of the invention, the information of the current access position of the UE can be used in a process of determining the reference cell by the positioning center, therefore, the positioning center can select a proper reference cell for accurately positioning the UE.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a positioning method and equipment thereof. Background technique [0002] Various positioning technologies can be used in the communication system to locate the user equipment. For example, the positioning of the user equipment (User Equipment, UE) may be implemented through an observed time difference of arrival (Observed Time Difference of Arrival, OTDOA) positioning method. When the positioning center decides to use the OTDOA method to locate the UE, the positioning center selects a reference cell according to the cell identity of the cell where the UE is currently located (that is, the serving cell), and sends the list of reference cells to the UE, and the UE measures the reference signal of the reference cell, and The time difference of each reference signal is calculated according to the measurement value, and then the time difference is sent to the positioning center a...
