Multi-SIM UE Dynamic Capability Management for Simultaneous Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-SIM devices face challenges in managing simultaneous connections to multiple networks, leading to underutilization of resources and inconsistent service quality due to lack of standardized support for dual Tx and dual Rx capabilities.
Innovation Solution
A multi-SIM UE is enabled to trigger requests to disable and reenable certain capabilities dynamically, allowing simultaneous connection to multiple networks by adapting radio resource configurations based on current needs and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-SIM UE provides full capabilities to multiple networks simultaneously, then the UE can maintain comprehensive service options, but the radio resources and service quality become underutilized and inconsistent
Solution Approach 1:
The patent implements dynamic capability management where the UE can change its capability configuration for different networks in real-time. The UE provides full capabilities during registration but can dynamically reduce capabilities when connected to multiple networks, allowing flexible adaptation to current operational needs and optimizing resource utilization across different network connections.
Solution Approach 2:
The patent changes the capability parameters dynamically based on the connection state. When the UE is connected to multiple networks simultaneously, it modifies the capability parameters by disabling certain capabilities for specific networks, thereby optimizing resource allocation and improving service quality while maintaining the ability to provide comprehensive services when needed.
2Adaptability or versatility
If a multi-SIM UE maintains simultaneous connections to multiple networks with full capabilities, then comprehensive communication is enabled, but service quality becomes inconsistent and resources are wasted
Solution Approach 1:
The system dynamically adjusts capability configurations based on actual connection states. When simultaneous connections to multiple networks are established, the UE dynamically reduces capabilities for each individual network connection, which stabilizes service quality by preventing resource exhaustion and ensuring consistent performance across all active connections.
Solution Approach 2:
The patent modifies capability parameters selectively for each network connection based on the overall connection state. By changing capability parameters dynamically when multiple networks are connected, the system maintains reliable service quality while preserving the ability to provide comprehensive communication services when needed.
3Productivity
If the UE disables capabilities to manage multiple networks, then resource management improves, but the UE loses some communication capabilities
Solution Approach 1:
The patent implements dynamic capability management where capabilities are disabled only when necessary for managing multiple simultaneous connections. When the UE needs to connect to additional networks, it dynamically adjusts which capabilities are disabled and which remain active, ensuring optimal resource management while preserving communication capabilities for when they are needed.
Solution Approach 2:
The system changes capability parameters selectively and dynamically. Capabilities are disabled for specific networks when multiple connections are active, but the UE maintains the ability to enable these capabilities when needed for single-network operations or when network conditions change, thus balancing resource management with communication capability flexibility.
Data Source
AI summary
A method performed by a UE having at least two SIM for simultaneous communication with two or more networks. The UE registers with a first wireless communications network associated with a first SIM, by providing, to a first network node, a first information comprising one or more first capabilities of the UE. The UE further registers with a second wireless communications network associated with a second SIM, by providing, to a second network node, a second information comprising one or more second capabilities of the UE. Upon being connected to the first wireless communications network and using the one or more first capabilities from the first information for a service, the UE triggers a first request to the first network node to disable a set of capabilities from the one or more first capabilities in the first information provided to the first network node.
