Base Station Capability Signaling for Multi-SIM Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM card terminals often experience communication conflicts due to overlapping paging occasions or resource management issues, leading to inefficiencies and resource wastage in communication processes.
Innovation Solution
A method where a base station sends system information carrying capability information to indicate its ability to resolve communication conflicts, allowing terminals to determine if the base station can solve specific conflict issues and only report problems when capable, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal reports all communication conflict problems to the base station, then the base station can potentially solve more conflicts, but communication resource wastage increases due to reporting unsolvable conflicts
Solution Approach 1:
The base station performs preliminary action by announcing its capability to solve specific communication conflict problems through system information before the terminal reports problems. This allows the terminal to pre-determine whether to report a problem based on the base station's announced capabilities, avoiding wasteful reporting of unsolvable conflicts and improving resource efficiency.
2Adaptability or versatility
If the base station announces detailed capability information, then the terminal can make more informed decisions about problem reporting, but system information complexity increases
Solution Approach 1:
The base station applies local quality by announcing capability information in a targeted and structured manner through system information, providing specific details about which communication conflict problems it can solve (e.g., paging occasion conflicts, random access conflicts) without overwhelming the terminal with unnecessary complexity. This enables the terminal to make informed decisions while keeping system information manageable.
