Dual SIM UE Registration Management for 5G Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication networks face inefficiencies in resource optimization, particularly with dual SIM user equipment (UE) where one SIM's call leads to unnecessary power consumption and resource wastage due to unutilized transceivers and improper registration management between 4G and 5G Radio Access Technologies (RATs).
Innovation Solution
The implementation of a method in user equipment (UE) that manages registration to either a 4G RAT or a 5G RAT based on weighted scores or parameters, allowing for dual or single registration modes, and suspending/downlink data management to optimize resource utilization during SIM events, ensuring efficient power use and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual SIM UE maintains registration to both 4G RAT and 5G RAT simultaneously, then service availability is improved, but resource utilization deteriorates
Solution Approach 1:
The patent implements dynamic registration management where the UE automatically switches between dual registration mode (both 4G and 5G RAT registered) and single registration mode (only one RAT registered) based on real-time detection of SIM events. This dynamic adaptation allows the system to optimize resource utilization while maintaining service availability according to actual operational conditions.
Solution Approach 2:
The system changes the registration state parameter from a static configuration to a dynamic one that responds to event detection. When a SIM event is detected, the system modifies the registration parameters to suspend or terminate one of the RAT registrations, thereby optimizing resource allocation while maintaining necessary service availability.
2Reliability
If transceiver is allocated to first SIM during call, then call service is improved, but power consumption increases
Solution Approach 1:
The patent extracts the second SIM from the active state by suspending its registration to either 4G RAT or 5G RAT when a call event is detected on the first SIM. This extraction action removes the unnecessary power consumption associated with the second SIM's transceiver while preserving the call service quality of the first SIM.
Solution Approach 2:
The system performs preliminary suspension of the second SIM's registration before the call event on the first SIM occurs. By detecting the incoming call event and proactively suspending the second SIM's RAT registration in advance, the system prevents unnecessary power consumption while ensuring the first SIM's call service is not affected.
3Productivity
If second SIM remains in idle state with suspended data connectivity, then resource wastage is reduced, but service continuity deteriorates
Solution Approach 1:
The patent implements dynamic suspension and resumption of data connectivity based on SIM event detection. When a call event is detected, the system dynamically suspends the second SIM's data connectivity to reduce resource wastage. When the call event concludes, the system dynamically resumes the data connectivity to maintain service continuity, thereby adapting to changing operational requirements.
Solution Approach 2:
The system performs preliminary suspension of data connectivity for the second SIM before resource optimization is needed. By detecting SIM events in advance and proactively suspending data connectivity, the system prevents resource wastage while ensuring data connectivity is restored when service continuity is required.
4Productivity
If UE uses weighted score for RAT selection, then registration optimization is improved, but system complexity increases
Solution Approach 1:
The patent introduces a weighted score parameter to evaluate and compare different RAT options (4G and 5G) for registration decisions. This parameter transformation converts complex multi-factor decision-making into a quantifiable scoring mechanism, improving registration optimization while keeping the implementation approachable through structured parameter evaluation.
