UE Registration Update Control for Returning NR Satellite Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication architecture for 5G systems using satellite radio access lacks clarity on procedures and information handling when user equipment (UE) returns to coverage from outside satellite access, particularly in discontinuous coverage scenarios.
Innovation Solution
A User Equipment (UE) equipped with a transmission and/or reception unit and controller, which receives configuration update commands and initiates a registration update procedure based on identification information from the network upon returning to satellite access, including parameters for Public Land Mobile Network (PLMN), Radio Access Technology (RAT) type, and access type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network provides discontinuous satellite coverage, then the UE can access the network when available, but the UE may lose coverage and unable to perform registration updates when returning to coverage
Solution Approach 1:
The network performs preliminary actions by sending configuration update commands or registration accept messages with first identification information before the UE actually returns to coverage. This prepares the UE in advance with the necessary identification information, so that when the UE returns to coverage, it can immediately and reliably perform registration updates without delay or failure.
2Loss of information
If the UE initiates registration update procedure upon returning to coverage, then the network can maintain updated UE location information, but the procedure and information handling are not clearly defined leading to control issues
Solution Approach 1:
The network provides feedback to the UE through configuration update commands or registration accept messages, sending first identification information that indicates when and how the UE should initiate registration updates. This feedback mechanism ensures the UE has clear, unambiguous instructions for maintaining updated location information, eliminating control issues while preventing information loss.
3Ease of operation
If the network sends identification information in configuration update command or registration accept message, then the UE can appropriately control registration update procedure, but the procedure must handle multiple parameters including PLMN, RAT type, access type, and area
Solution Approach 1:
The patent merges multiple parameters (PLMN, RAT type, access type, area) into a single unified first identification information element that is transmitted within the configuration update command or registration accept message. This consolidation simplifies the parameter management process for the UE, making it easier to control registration update procedures while handling all necessary parameters through a single integrated information structure.

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.
