Terminal Capability Negotiation for Multi-SIM Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a method for effectively negotiating and managing the capabilities of multi-SIM and multi-registration user equipment (UE) devices across different terminal identifiers, leading to potential data loss and reduced transmission reliability due to uncoordinated sharing of wireless connection capabilities.
Innovation Solution
A terminal capability negotiation method where the UE reports capability allocation information to the network side device, allowing for the configuration or reconfiguration of connections based on available capabilities across different terminal identifiers, ensuring that data transmission does not exceed the device's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-SIM and multi-registration UE camp and establish connections in multiple cells simultaneously, then the UE can access multiple networks and improve service availability, but the capability sharing between different terminal identifiers becomes uncoordinated, leading to potential data loss and reduced transmission reliability
Solution Approach 1:
The patent segments the UE capability information by terminal identifier, allowing separate capability reporting and negotiation for each terminal identifier (e.g., first UE ID and second UE ID). This enables the network to manage capabilities of each SIM card or registration instance independently, preventing capability conflicts and data loss while maintaining multi-network access.
2Productivity
If UE shares wireless connection capabilities across multiple terminal identifiers without coordination, then resource utilization improves, but uncoordinated capability sharing causes data loss and reduces transmission reliability
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports capability allocation information to the network side device for each terminal identifier. The network receives this feedback and performs coordinated capability negotiation, ensuring that capability sharing across multiple terminal identifiers is managed properly, preventing data loss while maintaining efficient resource utilization.
3Speed
If the network configures connections without receiving capability allocation information, then connection setup speed improves, but the network cannot properly manage UE capabilities, leading to data loss
Solution Approach 1:
The patent performs preliminary capability negotiation by having the UE report capability allocation information to the network side device before connection configuration is finalized. This preliminary action ensures the network has accurate capability information for each terminal identifier, enabling reliable connection management while maintaining efficient setup through pre-negotiated parameters.

AI summary
A terminal capability negotiation method includes: in a case that a terminal device has at least two terminal identifiers, reporting capability allocation information of the terminal device to a network side device, where the capability allocation information is used to indicate an available capability of at least one terminal identifier, and the at least one terminal identifier is a terminal identifier in the at least two terminal identifiers.
