Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-SIM terminal systems face challenges in efficiently switching between SIMs for communication, as not all network side devices support or configure appropriately for multi-SIM connection switching.
Innovation Solution
The proposed solution involves a capability determination method and apparatus that allow terminals to receive capability indication information from network side devices, determining the support capability for multi-SIM connection switching. This information enables terminals to assess and configure for multi-SIM switching based on the network's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal attempts to perform multi-SIM connection switching, then the terminal can switch between SIMs for communication operations, but the network side device may not support or configure appropriately for this switching
Solution Approach 1:
The terminal performs preliminary actions by sending capability indication information to the network side device before attempting multi-SIM connection switching. This allows the network side device to be pre-configured with the terminal's switching capabilities, ensuring reliable support when switching is actually needed. The capability indication includes parameters such as whether the terminal supports multi-SIM switching and conditions under which switching can occur.
Solution Approach 2:
The network side device provides feedback by sending capability indication information back to the terminal regarding its support for multi-SIM connection switching. This feedback mechanism allows the terminal to understand the network's capabilities and constraints, enabling the terminal to adjust its switching behavior accordingly. The feedback includes information about whether the network supports the switching and under what conditions.
2Ease of operation
If the terminal configures for multi-SIM switching without knowing network capabilities, then the terminal can attempt switching operations, but communication operations may fail or be interrupted
Solution Approach 1:
The terminal performs preliminary configuration by receiving capability indication information from the network side device before attempting multi-SIM connection switching. This preliminary action ensures that the terminal only attempts switching operations that are supported by the network, preventing communication failures. The capability indication provides advance knowledge of network support status and switching conditions.
3Device complexity
If the network side device does not provide capability indication information, then the system maintains simplicity, but the terminal cannot determine network support for multi-SIM switching
Solution Approach 1:
The capability indication information acts as an intermediary that bridges the terminal and network side device. This intermediary carries essential capability information between the two parties, enabling the terminal to determine network support for multi-SIM switching without significantly increasing system complexity. The capability indication is transmitted through existing signaling mechanisms, minimizing additional complexity.
