MUSIM UE RRC Connection Management for Dynamic Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively manage multiple RRC connections for Multi-Subscriber Identity Module (MUSIM) devices in 5G networks, particularly in handling measurement gap requirements during temporary capability restrictions.
Innovation Solution
A method and system for MUSIM UE to detect events associated with a second SIM, determine changes in measurement gap and network-controlled small gaps (NCSG) capabilities, and send assistance information to the network, receiving and configuring gap configurations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MUSIM UE supports multiple RRC connections simultaneously, then network coverage and connectivity are improved, but measurement gap management complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of measurement gap configurations based on the operational state of second SIM. When second SIM transitions between idle, inactive, and connected states, the system dynamically modifies measurement gap parameters for first SIM to optimize performance. This dynamic adaptation resolves the contradiction by allowing multiple RRC connections to coexist while automatically adjusting resources based on real-time conditions.
Solution Approach 2:
The system establishes feedback mechanisms where the MUSIM UE reports capability changes related to measurement gaps and network-controlled small gaps (NCSG) to the network apparatus. This feedback loop enables the network to adjust configurations accordingly, managing the complexity of multiple RRC connections through continuous information exchange and coordinated control.
2Productivity
If measurement gap requirements are dynamically adjusted, then network performance is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by having the MUSIM UE detect and determine capability changes in advance before they affect network operations. The UE identifies events associated with second SIM state changes and proactively reports relevant information about measurement gap and NCSG capability changes to the network apparatus, allowing the network to prepare appropriate configurations beforehand and reduce reactive signaling.
Solution Approach 2:
The system manages signaling overhead by focusing parameter changes on specific critical parameters (measurement gap and NCSG capabilities) rather than transmitting complete configuration sets. When second SIM state changes occur, the system selectively reports only the affected capability parameters, enabling network performance optimization with minimized information exchange.
