UE Network Reporting for Precise Location in Non-Terrestrial Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial communication networks with large coverage areas, user equipment (UE) cannot be accurately located to provide targeted services due to varying regional policies and control methods, leading to potential service disruptions.
Innovation Solution
User equipment reports network information of smaller coverage terrestrial cells to the service node of the larger coverage non-terrestrial network, enabling precise identification of the UE's location and allowing for tailored service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a non-terrestrial communication network with large coverage area is used, then the coverage area is improved, but the ability to accurately locate user equipment for targeted service provision deteriorates
Solution Approach 1:
The patent segments the large non-terrestrial coverage area by introducing terrestrial base stations with smaller coverage areas within the satellite cell. The UE reports information about detected terrestrial cells (such as cell ID, frequency, signal strength) to the satellite base station, which uses this segmented location information to determine the UE's precise position within the large coverage area, thereby resolving the contradiction between large coverage and precise location.
2Area of stationary object
If satellite base stations provide service over large areas, then the service coverage is improved, but the ability to apply regional policies and control methods deteriorates
Solution Approach 1:
The patent introduces terrestrial base stations as intermediaries between the satellite base station and the UE. The terrestrial base stations provide localized network information (such as PLMN ID, TAC, frequency information) that reflects regional policies and control methods. The satellite base station uses this intermediary information to understand the UE's regional context and apply appropriate regional policies, thus resolving the contradiction between broad service coverage and regional adaptability.
3Ease of operation
If user equipment operates in a large coverage non-terrestrial network, then the network accessibility is improved, but the ability to provide region-specific services deteriorates
Solution Approach 1:
The patent implements preliminary action by having the UE proactively detect and report terrestrial cell information before the satellite base station needs to provide region-specific services. The UE continuously monitors for terrestrial base stations and pre-collects network information (cell ID, frequency, signal strength, regional identifiers). This preliminary collection of regional information ensures that when service is needed, the satellite base station already has the necessary data to apply regional policies, thus resolving the contradiction between easy accessibility and retention of regional information.
