Multi-USIM Support Indication in Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks lack standardized methods for configuring and supporting Multi-USIM (Multiple Universal Subscriber Identity Module) features, which are optional and not uniformly supported, making it difficult for devices to simultaneously use multiple mobile communication networks.
Innovation Solution
A communication network arrangement and method that enables a communication terminal to request and receive notification on the support for simultaneous use of multiple mobile communication network subscriptions, allowing the terminal to adapt its behavior based on network capabilities, through a message exchange mechanism involving core network components like AMF and SMF.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication terminal uses multiple subscriber identity modules simultaneously, then the terminal can receive calls and services via both communication networks, but the network support and configuration mechanisms are not standardized leading to implementation-specific handling
Solution Approach 1:
The patent introduces a new parameter (MUSIM support indication) in the network response message that explicitly indicates whether the network supports multi-USIM functionality. This parameter change enables standardized configuration handling by providing clear network capability information to the terminal, resolving the implementation-specific variability issue.
Solution Approach 2:
The patent segments the capability negotiation process into distinct phases: terminal capability indication in the request message, and network capability indication in the response message. This segmentation allows independent configuration of terminal and network sides, reducing overall system complexity while enabling versatile Multi-USIM support.
2Adaptability or versatility
If the network provides detailed capability information to the terminal, then the terminal can adapt its behavior appropriately, but the message exchange complexity increases
Solution Approach 1:
The patent extracts the capability indication information from complex network configuration procedures and places it in a dedicated field within the response message. This extraction provides terminal adaptability through clear capability information while minimizing message exchange complexity by using a focused, standardized information structure.
3Ease of manufacture
If Multi-USIM features are supported without standardized configuration mechanisms, then implementation flexibility is maintained, but reliability of service delivery across different networks varies
Solution Approach 1:
The patent creates a universal configuration mechanism that works across different network implementations. The standardized message exchange with explicit capability indications ensures reliable service delivery while maintaining implementation flexibility, as the mechanism can be applied universally without requiring implementation-specific modifications.
