AI Technical Summary

Technical Problem

The positioning scheme in the existing NTN (non-terrestrial network) has the problem of large signaling overhead, especially when the number of satellites is small, it is difficult for user equipment to detect multiple satellites at the same time, resulting in an increase in signaling overhead during positioning.

Method used

By transmitting auxiliary information between the terminal and the first core network device, the terminal is configured to perform positioning measurements at multiple measurement times. The auxiliary information includes valid time information for positioning auxiliary data, PRS identification, SRS configuration list, schedule location time list, etc.

Benefits of technology

This reduces the signaling overhead between the terminal and the core network device, increases the chance of successful positioning, and avoids the increase in signaling overhead caused by configuring measurements separately at different times.

Abstract

The invention provides a positioning processing method and device, and relates to the technical field of communication. The method comprises the following steps: a terminal receives auxiliary information sent by a first core network device, wherein the auxiliary information is used for configuring positioning measurement of the terminal at a plurality of measurement times; the terminal performs positioning measurement according to the auxiliary information; wherein the auxiliary information comprises at least one of the following items: effective time information of positioning auxiliary data; positioning reference signal (PRS) identifications, wherein the PRS identifications are unique identifications in different area ranges; detecting a wireless signal SRS configuration list; scheduling a position time list; the association relationship between the first time of the scheduling position time list and the positioning auxiliary data is obtained. According to the scheme of the invention, the problem of high signaling overhead of a positioning scheme under an existing NTN (Network Temporary Network) is solved.
