Managing SOR Security Check Failure in 5G UE Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems face issues with Steering of Roaming (SoR) security check failures during registration procedures, which can impact ongoing services like URLLC, voice, and SMS, as they abruptly abort all services upon registration, leading to service disruptions.
Innovation Solution
A method and User Equipment (UE) that manage SoR security check failures by waiting for ongoing services to complete during mobility registrations and locally releasing signaling connections during initial registrations, allowing for a controlled PLMN selection based on stored registration types and SOR-CMCI configurations, including the use of timers to determine when to transition to idle mode or perform deregistration procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs a SOR security check during registration procedure, then security is improved, but service continuity deteriorates due to abrupt service abortion upon failure
Solution Approach 1:
The patent makes the UE's response to SOR security check failure dynamic by introducing the registration type parameter. Instead of a fixed response, the UE now adapts its behavior based on whether the registration is initial or mobility-related, allowing service continuity to be maintained for mobility registrations while still ensuring security for initial registrations.
Solution Approach 2:
The patent changes the parameter of registration type (initial vs. mobility) to determine the appropriate response to SOR security check failure. This parameter change enables differentiated handling: initial registrations trigger service abortion while mobility registrations trigger service completion waiting, thus resolving the contradiction between security and service continuity.
2Reliability
If the UE aborts all services upon SOR security check failure, then security is enforced, but service disruption increases
Solution Approach 1:
The patent applies local quality by treating different registration types differently. Instead of uniformly aborting all services upon SOR security check failure, the UE now applies localized responses: aborting services only for initial registrations while allowing services to complete for mobility registrations. This selective approach reduces unnecessary service disruption while maintaining security enforcement where critical.
Solution Approach 2:
The patent segments the registration procedure into two distinct categories: initial registration and mobility registration. This segmentation allows the system to apply different security enforcement strategies to each segment, reducing overall service disruption by avoiding unnecessary abortions in mobility scenarios while maintaining security in initial registration scenarios.
3Duration of action of moving object
If the UE waits for ongoing services to complete during mobility registration, then service continuity is improved, but registration processing time increases
Solution Approach 1:
The patent applies preliminary action by having the UE check the registration type before executing the SOR security check failure response. This preliminary classification allows the system to prepare the appropriate response in advance, avoiding unnecessary service abortions and reducing overall processing time while maintaining service continuity where applicable.
4Adaptability or versatility
If the UE performs PLMN selection upon SOR security check failure, then network selection capability is improved, but service interruption increases
Solution Approach 1:
The patent makes the PLMN selection timing dynamic based on registration type. For initial registrations, PLMN selection is triggered immediately upon SOR security check failure. For mobility registrations, PLMN selection is delayed until after ongoing services complete. This dynamic approach maintains PLMN selection capability while minimizing service interruption.
