MBSR Authorization Handling for 5G Discontinuous Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in handling mobile base station relay (MBSR) user equipment registration, emergency calls, and managing unavailability periods in discontinuous coverage scenarios, particularly in 5G and emerging 6G systems.
Innovation Solution
The proposed solution involves a method and system where a network entity identifies changes in MBSR authorization state, transmits authorization indications to a base station, receives completion indications for non-authorized MBSR operations, and performs de-registration procedures with the MBSR. This ensures a graceful release of resources and maintains service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network entity continuously monitors MBSR authorization state changes to ensure proper service handling, then service reliability is improved, but signaling overhead and network entity processing complexity increase
Solution Approach 1:
The MBSR UE autonomously monitors its own authorization state and initiates de-registration procedures when authorization is lost, eliminating the need for continuous network entity monitoring. The UE independently determines when to notify the network, reducing network processing complexity while maintaining service reliability through self-aware authorization tracking.
Solution Approach 2:
The network entity sends authorization status indications to the MBSR UE, creating a feedback loop where the UE receives periodic or event-triggered authorization state updates. This allows the UE to autonomously respond to authorization changes without requiring continuous network monitoring, balancing reliability with reduced network complexity.
2Reliability
If the network entity immediately performs de-registration procedures when MBSR authorization is lost, then service continuity for other UEs is improved, but service disruption for the MBSR UE increases
Solution Approach 1:
The network entity sends an authorization status indication to the MBSR UE in advance, allowing the UE to prepare for de-registration. The UE then initiates the de-registration procedure with a delay or at a convenient time, rather than immediate forced de-registration. This preliminary notification allows graceful service transition, maintaining continuity for other UEs while reducing disruption for the MBSR UE.
Solution Approach 2:
The de-registration timing is made dynamic rather than fixed. The network can indicate authorization loss, but the actual de-registration execution time is flexible, allowing the MBSR UE to complete ongoing services or perform handover before de-registration. This dynamic approach balances immediate service continuity needs with minimizing individual UE disruption.
3Adaptability or versatility
If the system supports emergency calls during discontinuous coverage periods, then emergency service accessibility is improved, but network resource consumption increases
Solution Approach 1:
Instead of maintaining continuous network connection during discontinuous coverage, the system uses periodic check-ins or event-triggered connections. The MBSR UE maintains emergency service capability by periodically monitoring for network availability or by establishing connections only when needed. This periodic approach ensures emergency accessibility while significantly reducing network resource consumption compared to continuous connection maintenance.
