UE Registration Update Triggering After NR Satellite Coverage Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication architecture for 5G systems using satellite radio access lacks clarity on procedures and information exchange for registration updates when user equipment (UE) moves in and out of satellite coverage, leading to unclear UE behaviors and processing.
Innovation Solution
A User Equipment (UE) with a transmission and/or reception unit that receives a message from a network via satellite access, initiating a registration update procedure based on third identification information to manage network connections effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE connected to the network via NR satellite access providing discontinuous coverage, then the UE can communicate with the network when satellite coverage is available, but the procedures and information exchange for registration updates when the UE moves in and out of satellite coverage are not clarified
Solution Approach 1:
The patent introduces specific identification information (third identification information) as an intermediary element in the message exchanged between the network and UE. This identification information serves as a clear trigger signal that mediates the registration update procedure, eliminating the ambiguity about when and how the UE should perform registration updates while maintaining satellite access capability.
2Reliability
If the network requests the UE to initiate a registration update procedure via satellite access, then the network can maintain accurate UE location information, but the UE behaviors and processing requirements are not clearly defined
Solution Approach 1:
The network performs preliminary action by including third identification information in messages sent to the UE before the UE actually needs to update its registration. This advance notification allows the UE to prepare and execute the registration update procedure smoothly, clearly defining UE behaviors while ensuring the network maintains accurate location information.
Solution Approach 2:
The patent establishes a feedback mechanism where the network sends third identification information to the UE, triggering the UE to perform registration update and send back updated location information. This closed-loop feedback ensures both reliable network information and clearly defined UE operational requirements.

AI summary
Provided are identification information for transmitting and/or receiving information necessary for performing a network-initiated registration update procedure performed in a case that a UE returns to coverage from outside of the coverage of NR satellite access between the UE and a network in advance, performing of the registration update procedure based on the identification information, control of a form of performing the registration update procedure, and control of a condition for performing the registration update procedure.
