Multi-SIM Terminal Capability Indication for Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM terminals, the inability to determine whether a terminal supports multi-SIM connection switching leads to inefficient resource allocation and configuration issues by base stations, as not all terminals can seamlessly switch between SIMs during communication operations.
Innovation Solution
A capability indication method where terminals send capability information to network side devices indicating their ability to perform multi-SIM connection switching, allowing the network to make appropriate configurations based on the terminal's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all terminals are set to support multi-SIM connection switching by default, then communication switching capability is improved, but configuration compatibility and resource allocation efficiency deteriorate for terminals that do not support this feature
Solution Approach 1:
The patent changes the parameter state by introducing capability indication information that dynamically reveals whether a terminal supports multi-SIM connection switching. Instead of using a fixed default configuration, the system now adapts parameters (configuration settings) based on the actual capability state reported by the terminal, resolving the contradiction between universal adaptability and configuration compatibility.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal reports its capability status to the network side device through capability indication information. This feedback loop allows the network to adjust configurations appropriately based on actual terminal capabilities, preventing configuration errors and resource waste while maintaining support for terminals with or without multi-SIM switching capability.
2Productivity
If capability indication information is implemented, then resource allocation efficiency is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent applies partial action by implementing capability indication only for the specific multi-SIM connection switching feature rather than comprehensive capability reporting. This selective approach provides sufficient information for efficient resource allocation without the excessive signaling overhead that would result from reporting all terminal capabilities, thus balancing productivity improvement with device complexity management.
