Multi-SIM Problem Notification for Base Station Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM terminals often experience performance degradation due to conflicts between SIM cards during simultaneous communication, and existing solutions lack a standardized method to effectively manage these issues, leading to inefficiencies and user experience problems.
Innovation Solution
A method and device that allow terminals to send multi-SIM problem notifications to base stations, enabling the base stations to determine the occurrence of conflicts and provide targeted solutions based on their capabilities, reducing unnecessary notifications and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SIM cards conduct communication at the same time, then the terminal supports multi-SIM functionality, but performance is degraded due to conflicts between SIM cards
Solution Approach 1:
The terminal feeds back multi-SIM problem notifications to the base station when conflicts occur between SIM cards. This feedback mechanism enables the base station to detect the conflict state and adjust its scheduling decisions, transforming the terminal's passive conflict victim into an active participant in conflict resolution through information feedback.
Solution Approach 2:
The base station acts as an intermediary that receives conflict notifications from the terminal and mediates the resource allocation between multiple SIM cards. By introducing this intermediary coordination layer, the system resolves conflicts that would otherwise directly degrade terminal performance.
2Productivity
If the terminal sends multi-SIM problem notifications to the base station, then targeted problem management is enabled, but communication overhead increases
Solution Approach 1:
The terminal sends multi-SIM problem notifications selectively rather than continuously - only when actual conflicts occur or are predicted to occur. This partial action approach avoids the energy waste of constant notification transmission while ensuring that meaningful conflict information reaches the base station for timely resolution.
3Ease of operation
If the base station determines specific multi-SIM problems from terminal notifications, then targeted solutions can be provided, but system complexity increases
Solution Approach 1:
The terminal extracts and reports only the essential multi-SIM conflict information to the base station, separating the detection function (at terminal) from the resolution function (at base station). This extraction approach reduces the information burden on the base station while maintaining its ability to provide targeted solutions.
4Speed
If multi-SIM problem notifications are sent frequently, then the base station can respond to conflicts timely, but resource waste increases
Solution Approach 1:
The notification mechanism operates on demand rather than continuously - notifications are sent only when multi-SIM conflicts actually occur or are predicted to occur. This partial action ensures timely conflict response while avoiding the resource waste of frequent unnecessary notifications during normal operation.

AI summary
A method and apparatus for information sending and receiving. The information sending method comprises: sending a multi-SIM problem notification to a base station, wherein the multi-SIM problem notification is configured to notify the base station that a multi-SIM problem is currently occurring or will occur in a terminal.
