[0223] Such as image 3 As shown, the first embodiment of the present invention provides a positioning method applied to the base station side, including:

[0224] Step 11, acquiring the positioning measurement information of the terminal, the positioning measurement information including the coverage enhancement level (CE level) where the terminal is currently located and the serving cell identity of the terminal;

[0225] Step 12: Receive a positioning measurement request triggered by a preset positioning entity, where the positioning measurement request includes an instruction to perform positioning measurement on the terminal using the coverage enhancement level;

[0226] Step 13: Send the positioning measurement information of the terminal to a preset positioning entity according to the positioning measurement request, so that the preset positioning entity can locate the terminal according to the positioning measurement information.

[0227] In the first embodiment of th...

Abstract

The invention provides a positioning method and a positioning device. The positioning device applied to a base station side comprises the following steps: acquiring the positioning measurement information of a terminal; receiving a positioning measurement request triggered by a preset positioning entity, wherein the positioning measurement request contains an indication for positioning and measuring the terminal by virtue of a coverage enhancement grade; and sending positioning measurement information of the terminal to the preset positioning entity according to the positioning measurement request so as to drive the preset positioning entity to position the terminal according to the positioning measurement information. According to the embodiment of the invention, the terminal is roughly positioned by a network side through the coverage enhancement grade and a service cell marker of the terminal, so that the extra expenditure of the terminal caused by the positioning of the terminal in the coverage enhancement grade range is avoided, the complexity of the terminal is reduced, and the power consumption of the terminal is saved; or the terminal is subjected to positioning measurement by the network side through a repeated sending property of the coverage enhancement grade, so that a relatively accurate positioning measurement result is obtained, and the positioning measurement precision is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a positioning method and device. Background technique [0002] The Narrow Band Internet of Things (NB-IoT) work phase (Work Item, WI) was passed and started in the 3GPP Release 13 (Release 13) phase. [0003] The goal of the narrowband Internet WI phase is to standardize the wireless access of the Cellular Internet of Things (CIoT). The technology is expanded based on LTE / LTE-A, and the main network characteristics / objectives considered are: enhanced indoor coverage, support for a large number of low-speed device access, low latency sensitivity, reduced device cost, reduced device power consumption, optimized network architecture, etc. [0004] Some of the currently recognized characteristics of NB-IOT communication that may exist are: [0005] NB-IOT terminals have low mobility; [0006] The time for data transmission between the NB-IOT terminal and the netwo...
