US 12,634,871 B2 · Positioning measurement method and apparatus

Abstract

A positioning measurement method and an apparatus are provided. The method includes: after a first network element receives, from a second network element, an indication of obtaining location information of a terminal, the first network element requests at least one access network device to broadcast a message. The terminal starts to send a reference signal upon receiving the message broadcast. The first network element further requests the at least one access network device to measure the reference signal. Upon receiving a measurement request, the access network device measures the received reference signal, to obtain a corresponding measurement result; then sends the measurement result to the first network element. According to the present application, during uplink positioning, a terminal in a non-connected state does not need to re-enter a connected state, thereby reducing a delay for positioning the terminal, reducing energy consumption of the terminal, and improving positioning efficiency.

Dependent claims

A positioning measurement method, wherein the method comprises:

receiving, by a first network element, a first message from a second network element, wherein the first message indicates the first network element to obtain location information of a terminal;
and
sending, by the first network element, a broadcast request and a measurement request to at least one access network device, wherein the broadcast request indicates to broadcast a second message, the measurement request indicates to measure a reference signal, the second message indicates the terminal to send the reference signal, and the at least one access network device comprises an access network device that the terminal camps on;
and
receiving, by the first network element, a measurement result from the at least one access network device, wherein the measurement result comprises a timestamp and/or a sounding reference signal (SRS) resource identifier of a first SRS resource that are/is used by the first network element to determine that the measurement result is obtained by measuring the terminal.
