Solution Overview
Problem
Existing communication systems face challenges in performing positioning measurements on terminals that cannot communicate with a core network device.
Innovation Solution
A method and apparatus that enable a first terminal to select a third terminal capable of communicating with a first network element to initiate a positioning procedure on behalf of the first terminal, allowing for the determination of a positioning measurement result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first terminal cannot communicate with the first network element, then the positioning procedure cannot be completed directly, but introducing a third terminal to assist increases system complexity
Solution Approach 1:
The patent introduces a third terminal as an intermediary to facilitate positioning measurements when the first terminal cannot directly communicate with the first network element. The third terminal receives requests from the first terminal, performs positioning measurements with the first network element, and relays results back, thereby resolving the communication barrier while maintaining positioning functionality.
2Reliability
If a third terminal is selected from discovered second terminals, then positioning can be performed indirectly, but the selection process increases operational complexity
Solution Approach 1:
The first terminal autonomously selects a suitable third terminal from the discovered second terminals based on predefined criteria without requiring manual intervention. The selection process is automated, where the terminal evaluates available terminals and independently determines which one to use for positioning assistance, thereby reducing operational complexity.
3Measurement precision
If the first terminal requires assistance from the first network element, then positioning accuracy can be improved, but the communication requirement creates a constraint
Solution Approach 1:
The third terminal acts as a mediator that enables the first terminal to indirectly access the first network element's positioning assistance. By routing communication through the third terminal, the system maintains the benefit of network element assistance for improved accuracy while adapting to the first terminal's communication limitations.

AI summary
Provided in the present disclosure are a positioning method and apparatus, and a device and a storage medium. The method comprises: when a first terminal cannot communicate with a first network element and the assistance of the first network element is required to complete a positioning process of the first terminal, the first terminal selecting a third terminal from among at least one second terminal, which is discovered by the first terminal, wherein the third terminal can communicate with the first network element; and sending first information to the third terminal, wherein the first information is used for requesting the third terminal to initiate a first flow to the first network element, and the first flow is used for determining a positioning measurement result of the first terminal. By means of the method provided in the embodiments of the present disclosure, when a first terminal cannot communicate with a first network element, it is possible to ensure that a positioning measurement of the first terminal is successfully implemented.
