Terminal Positioning via Primary and Secondary Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR positioning technology, terminal positioning is hindered when there is no proper positioning server available within the network coverage area to provide a positioning service.
Innovation Solution
A method and apparatus that allow a terminal to acquire positioning service information from a target terminal, determine a primary and secondary positioning terminal based on this information, and perform positioning using these terminals to obtain its location, even without a network coverage area with a proper positioning server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional positioning server-based positioning is used, then positioning service can be provided when server is available, but positioning cannot be implemented when no proper positioning server is present in the network coverage area
Solution Approach 1:
The patent introduces peer terminals as intermediary positioning assistants that can provide positioning services when traditional positioning servers are unavailable. The first terminal communicates with second and third terminals directly to perform positioning measurements, using these terminals as mediators to achieve positioning without requiring a positioning server in the network coverage area.
Solution Approach 2:
The patent enables terminals to perform positioning services for themselves and other terminals without relying on external positioning servers. The first terminal autonomously performs positioning measurements with second and third terminals, calculates positioning results, and determines its own location,实现ing self-service positioning in areas without positioning server support.
2Productivity
If positioning server is required for all positioning operations, then centralized control is maintained, but positioning efficiency decreases and user experience deteriorates in areas without server coverage
Solution Approach 1:
The patent segments the centralized positioning service into distributed terminal-based positioning operations. Instead of requiring all positioning operations to go through a central positioning server, the system divides positioning functions among multiple terminals, with each terminal capable of performing measurements and calculations locally, thereby improving positioning efficiency and user experience in areas without server coverage.
3Adaptability or versatility
If direct terminal-to-terminal communication is established for positioning, then positioning can occur without positioning server, but communication complexity increases
Solution Approach 1:
The patent utilizes existing direct communication interfaces (such as sidelink interfaces in 5G systems) that terminals already possess for general communication purposes. By repurposing these universal communication capabilities for positioning measurements, the system enables positioning without servers without adding significant communication interface complexity, as the same interface serves both general communication and positioning functions.
Data Source
AI summary
Provided in the present application are a positioning method and apparatus, and a terminal and a storage medium. On a first terminal side, the positioning method includes: acquiring positioning service information of a target terminal; determining from the target terminal, according to the positioning service information, a primary positioning terminal for providing a primary positioning service and a secondary positioning terminal for providing a secondary positioning service; and performing positioning for a location of a first terminal based on the primary positioning terminal and the secondary positioning terminal. Since the positioning of the first terminal can be assisted by the primary positioning terminal and the secondary positioning terminal, the location of the first terminal can be accurately positioned even if a network coverage area where the first terminal is located does not have a proper positioning server therein to provide a positioning service.
