Multi-USIM Switching for Emergency Service Paging Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing multi-USIM features during emergency modes, leading to unintended consequences such as service disruptions and inefficiencies in paging and connection management.
Innovation Solution
A method and system for disabling multi-USIM features in emergency scenarios by sending a configuration update command message indicating registration for emergency services, allowing the UE and network to behave as if multi-USIM features are not supported, and using alternative IMSI for paging occasion calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-USIM features are enabled in emergency mode, then service coverage and accessibility are improved, but service disruptions and inefficiencies occur due to unintended consequences in paging and connection management
Solution Approach 1:
The patent extracts the multi-USIM feature from the emergency mode operation by disabling it when emergency service is detected. The network device determines that the terminal is registered for emergency service and sends a configuration update command to disable multi-USIM features, thereby eliminating the service disruptions caused by multi-USIM in emergency scenarios while maintaining emergency service coverage
Solution Approach 2:
The patent implements dynamic switching of multi-USIM feature status based on service mode. The system transitions multi-USIM from enabled to disabled state when emergency service registration is detected, allowing the system to adapt its functionality according to the operational context - enabling both broad service coverage and reliable emergency service operation
2Adaptability or versatility
If multi-USIM features are supported during emergency service, then device functionality is enhanced, but paging and connection management inefficiencies arise
Solution Approach 1:
The patent removes multi-USIM feature support from emergency service operations by disabling it upon detecting emergency service registration. This extraction eliminates the paging and connection management inefficiencies that arise from multi-USIM complexity during emergency scenarios, while the device retains full functionality for normal services
Solution Approach 2:
The system dynamically adjusts multi-USIM feature availability based on service type. During emergency service, multi-USIM is disabled to optimize paging efficiency and connection management. During normal services, multi-USIM remains enabled to provide enhanced device functionality. This dynamic adaptation resolves the contradiction between functionality and efficiency

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a mobile communication system is provided. The method comprises receiving, from an access management function (AMF) entity via a base station, a configuration update command message in case that the UE supporting a multi universal subscriber identity module (MUSIM) feature is not registered for an emergency service, and disabling the MUSIM features based on the received configuration update command message. The configuration update command message includes registration result information indicating that the UE supporting the MUSIM features is registered for the emergency service.
