Multi-SIM UE Capability Profile Switching for Network Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM devices face challenges in managing simultaneous communication with multiple networks, leading to network performance deterioration and user experience issues, particularly in scenarios where one network attempts to communicate while the other is paged, without standardized technical support.
Innovation Solution
The UE indicates reduced capabilities to one network to prioritize communication with another, using overheating indications or capability profile switching to manage resource allocation efficiently, allowing simultaneous connections with multiple SIMs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE prioritizes communication with one network, then communication quality with that network is improved, but the ability to receive pages or communicate with the other network deteriorates
Solution Approach 1:
The UE dynamically switches between different capability profiles (full capabilities, reduced capabilities, minimal capabilities) based on the communication state of each SIM. This allows the UE to adapt its resource allocation in real-time, prioritizing one network when needed while maintaining basic connectivity to the other, thus resolving the contradiction between communication quality and multi-network adaptability
Solution Approach 2:
The UE changes its reported capability parameters to the network by selecting from predefined capability profiles. When one SIM is in active communication, the UE reports reduced or minimal capabilities for that SIM, allowing the network to adjust scheduling accordingly. This parameter change enables the UE to maintain reliable communication with the active network while preserving the ability to receive pages from the other network
2Adaptability or versatility
If the UE supports simultaneous communication with multiple networks, then multi-network connectivity is improved, but network performance deteriorates due to lack of standardized management
Solution Approach 1:
The UE segments its communication capabilities into distinct profiles (full, reduced, minimal) that can be independently applied to different SIMs. This segmentation allows the network to understand and manage UE resources more effectively, preventing network performance deterioration by providing clear visibility into UE capability constraints
Solution Approach 2:
The UE provides feedback to the network about its capability state through capability profile indication. This feedback mechanism allows the network to adjust its scheduling and resource allocation decisions, ensuring optimal network performance while supporting multi-network connectivity. The network can use this information to avoid scheduling conflicts and manage UE resources efficiently
3Productivity
If the UE uses full capabilities for one network, then communication performance with that network is improved, but resource availability for the other network is reduced
Solution Approach 1:
The UE dynamically adjusts its capability reporting based on which SIM is currently prioritized. When SIM 1 requires full capabilities for high-performance communication, the UE reports full capabilities to network 1 and minimal or reduced capabilities to network 2. This dynamic adjustment ensures that resource allocation matches actual communication needs, maintaining high performance where required while preserving minimal resource availability for the other network

AI summary
Systems and methods are disclosed herein related simultaneous registration of wireless communication device having multiple Subscriber Identity Modules (SIMs) with two or more networks. In one embodiment, a method performed by a wireless communication device having multiple SIMs comprises registering with a first network associated with a first SIM and registering with a second network associated with a second SIM such that the wireless communication device is simultaneously registered with both the first network and the second network. The method further comprises providing, to a network node associated with the first network, capability information for the wireless communication device that indicates less than full capabilities of the wireless communication device. In this manner, the wireless communication device ensures that it will have sufficient resources to maintain simultaneous connections to both the first and second network.
