Dual-SIM Connection State Adjustment for Paging Conflict Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-card terminals, communication conflicts arise when one SIM card is active and another receives paging information, leading to conflicting communication actions.
Innovation Solution
A method for connection indication and adjustment involving a base station and terminal, where the base station receives request information from a SIM card to leave a connected state, determines the leaving reason, and sends indication information to adjust the SIM card to enter a non-connected state or maintain the connected state based on service type, priority, or preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal allows one SIM card to remain in connected state for ongoing communication, then communication continuity is improved, but communication conflicts occur when another SIM card needs to communicate
Solution Approach 1:
The patent implements dynamic connection state management where SIM cards can transition between connected and non-connected states based on real-time communication needs. The base station receives indication information from the terminal and dynamically adjusts which SIM card maintains connected state, allowing flexible adaptation between different communication scenarios and resolving conflicts between multiple SIM cards.
2Adaptability or versatility
If the terminal switches SIM card to non-connected state to resolve conflict, then communication conflict is resolved, but communication interruption occurs for ongoing service
Solution Approach 1:
The patent employs preliminary action by having the terminal proactively send indication information to the base station before communication conflicts fully manifest. The base station receives this indication and pre-adjusts the connection states of SIM cards, allowing smooth transitions without interrupting ongoing communications. This anticipatory mechanism ensures communication continuity while maintaining multi-card adaptability.

AI summary
The present disclosure provides a method for a connection indication, which includes receiving request information for leaving a connected state sent by a first SIM card in a terminal, wherein the request information includes a leaving reason for leaving the connected state; and sending, according to the leaving reason, indication information to the terminal, wherein the indication information is used to indicate the first SIM card to enter a non-connected state or not to enter the non-connected state.
