Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

It should be noted that, in the prior art, as shown in fig. 1, an lmf (location Management function) in a 5G positioning architecture applicable to a next Generation Radio Access network (NG-ran) is a positioning Management functional unit, and is responsible for selecting a positioning method, triggering corresponding positioning measurement, and calculating a final positioning result and accuracy; NG-RAN: positioning reference signals can be sent, or positioning measurement can be carried out based on auxiliary information; the NR side node may control a plurality of TRPs (Transmission-Reception Point)/tps (Transmission Point) to transmit and/or receive a positioning reference signal; UE: positioning reference signals can be sent, or positioning measurement can be carried out based on auxiliary information; positioning end results and accuracy may also be calculated based on the measurements.

In the prior art, as shown in fig. 2, a flow of DL-PRS configuration is: the LMF may obtain, through the process shown in fig. 2, DL PRS configuration information sent by a certain NR side node, where the DL-PRS configuration includes a DL-PRS resource configuration of a TRP (Transmission-Reception Point) under the NR side node.

In the prior art, as shown in fig. 3, a flow of DL-PRS configuration is: the UE can obtain the DL-PRS configuration required to be measured through the LPP procedure (LMF unsolicited or UE solicited) shown in fig. 3.

For the current R17 positioning method, the goal is to increase the network efficiency, however, the current DL-PRS configuration mode is that the network side node does not intermittently send DL-PRS configuration to the terminal equipment UE, and even if the UE does not have the positioning requirement currently, the network side node still sends DL-PRS configuration, resulting in lower DL-PRS configuration efficiency. To solve the problem, an embodiment of the present application provides a positioning pilot configuration method, which transmits a configuration request for requesting activation and/or deactivation of DL-PRS configuration to a positioning management function unit LMF or an access network device, so that DL-PRS may be activated and/or deactivated based on the request, thereby improving network efficiency of configuring DL-PRS.

The following explains and explains the positioning pilot configuration method, apparatus, terminal device, access network device, and storage medium provided in the present application in detail by using specific embodiments.

It should be noted that, in the following description, since the method and the apparatus are based on the same application concept, and the principles of solving the problems of the method and the apparatus are similar, the implementation of the apparatus and the method can be mutually referred, and repeated details are not repeated.
