Multi-USIM Terminal Capability Coordination for Simultaneous Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for multi-USIM terminal devices are not suitable for scenarios involving simultaneous connections across different communication standards, leading to issues such as interference and capability exceeding limitations.
Innovation Solution
The method involves determining whether a connection should be established with a second network device and, if so, transmitting an indication to the first network device to release a portion of its capability for simultaneous connections, ensuring capability coordination across both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-USIM terminal device establishes simultaneous connections with multiple networks, then the device can communicate with multiple networks at the same time, but the terminal device's capability may be exceeded causing interference and connection instability
Solution Approach 1:
The patent implements dynamic capability coordination by allowing the terminal device to indicate its current capability status to the network device. The network device then dynamically adjusts resource allocation and connection parameters based on the terminal's real-time capability feedback, enabling the system to adapt to changing connection conditions while maintaining reliability.
Solution Approach 2:
The patent establishes a feedback mechanism where the terminal device sends capability indication information to the network device. This feedback loop allows the network to be aware of the terminal's capability constraints and adjust its behavior accordingly, preventing capability exceeding and ensuring stable simultaneous connections.
2Power
If the terminal device maintains full capability for each USIM independently, then each network connection can operate at maximum performance, but the total capability requirement exceeds what the terminal can provide
Solution Approach 1:
The patent changes the parameter representation by introducing capability indication information that communicates the terminal's actual available capability under simultaneous connection conditions. This allows the network to adjust transmission power and other parameters to match the terminal's real capability, enabling simultaneous connections within the terminal's power constraints.
Solution Approach 2:
The patent applies partial action by allowing the terminal to indicate reduced capability for certain functions when simultaneous connections are active. Instead of requiring full capability for each connection, the system accepts partial capability allocation, enabling simultaneous connections to be established with reduced but sufficient performance levels.

AI summary
Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A terminal device in a connected state with a first network device determines that a connection is to be established with a second network device, and transmits, to the first network device, an indication that a portion of capability of the terminal device for a first subscriber identity module is to be released for simultaneous connections with the first and second network devices. Thereby, partial capabilities of the terminal device for the first subscriber identity module are released so that the terminal device has spare capabilities for a second subscriber identity module.
