Problems solved by technology

[0004] However, the enhanced cell positioning measurement report and the enhanced cell positioning measurement initial response only carry the location information of the serving cell where the terminal is currently located, but cannot carry the location information of the adjacent cell corresponding to the serving cell. Therefore, through the enhanced When locating a terminal using the cell positioning technology, the E-SMLC needs to obtain the location information of the adjacent cell through other means.
However, when the eNode B is capable of obtaining the location information of the adjacent cell, for example: when the adjacent cell and the serving cell are located in the same physical eNode B, the E-SMLC also obtains the location information of the adjacent cell through other means, so that both Increase positioning delay and waste network resources

Embodiment Construction

[0044] In the embodiment of the present invention, a positioning request is received, and measurement is started according to the positioning request; when it is determined that the adjacent cell of the serving cell where the terminal is located is a cell in the current base station, the location information of the adjacent cell is obtained, and the The positioning response of the above location information.

[0045] Here, the receiving the positioning request is: the base station receives the positioning request sent by the E-SMLC; correspondingly, the sending the positioning response is: the base station sends the positioning response to the E-SMLC, wherein the positioning response carries the location of the adjacent cell The location cell of the information.

[0046] Specifically, the sending the positioning response carrying the location information includes: writing the obtained location information of the adjacent cell into a preset location cell; after that, encapsulat...

Abstract

Provided is an enhanced cell-ID (E-CID) terminal positioning method, comprising: receiving a positioning request, and enabling measurement according to the positioning request; when determining that a neighboring cell of a serving cell where the terminal is located is a cell located in the current eNode B, acquiring the position information of the neighboring cell; and transmitting a positioning response carrying the position information. Also provided are an alternative E-CID terminal positioning method, E-CID terminal positioning system, eNode B and computer storage medium.

Description

technical field [0001] The present invention relates to a cell positioning technology, in particular to an enhanced cell (E-CID, Enhanced Cell-ID) terminal positioning method and system, and a base station. Background technique [0002] The cell positioning technology (CID Positioning Method) is to estimate the current position of the UE through the position coordinates of the serving cell where the user equipment (UE, User Equipment) is located and the measurement information related to the serving cell between the terminal and the serving cell. The enhanced cell positioning technology is based on the cell positioning technology and uses related measurements of adjacent cells or other UEs to improve positioning accuracy. [0003] Currently, the enhanced cell positioning technology requires the evolved base station (eNode B, Evolved Node B) to pass the enhanced cell positioning measurement report (E-CID MEASUREMENT REPORT), or the enhanced cell positioning measurement initia...
