Base Station Capability Exchange for Multi-SIM Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card communication conflicts in terminals, where multiple Subscriber Identity Module (SIM) cards are used, lead to communication inefficiencies that existing technologies struggle to resolve effectively, as conflicts between SIM cards can disrupt communication processes.
Innovation Solution
A method for capability exchange between base stations and core networks is implemented, where capability information is exchanged to determine and resolve multi-card communication conflicts, allowing the networks to collaborate in solving these issues by identifying and utilizing the capabilities of both base stations and core networks to address specific conflict types and solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SIM cards are provided in a terminal to enable diverse communication services, then the terminal's communication versatility is improved, but communication conflicts between SIM cards occur which deteriorates communication efficiency
Solution Approach 1:
The patent introduces a capability exchange mechanism as an intermediary between the terminal and the network (base station/core network). This intermediary exchanges capability information about multi-card conflict resolution methods, allowing the network to select appropriate resolution strategies without direct intervention in terminal operations. The capability exchange message acts as a mediator that coordinates between multiple SIM cards and the network infrastructure.
Solution Approach 2:
The patent changes the parameter of network capability information exchange to resolve communication conflicts. By exchanging capability information that describes different conflict resolution methods (such as prioritization strategies, resource allocation methods, or conflict avoidance mechanisms), the system adapts its behavior based on the exchanged parameters, enabling efficient resolution of conflicts between multiple SIM cards.
2Productivity
If the network resolves multi-card communication conflicts through direct intervention, then communication efficiency is improved, but the complexity of network management increases
Solution Approach 1:
The patent applies preliminary action by exchanging capability information before actual communication conflicts occur. The base station and core network pre-exchange information about their conflict resolution capabilities and preferences, so that when conflicts arise, the resolution process is already prepared and can be executed efficiently without complex real-time analysis or intervention.
Solution Approach 2:
The capability exchange mechanism establishes a feedback loop where the terminal provides information about its multi-card configuration and communication needs, the network responds with appropriate capability information, and this feedback continues to optimize conflict resolution. This feedback mechanism simplifies network management by automating the capability selection process rather than requiring complex manual configuration.

AI summary
A method for capability exchange performed by a base station includes: exchanging, with a core network, capability information for solving a multi-card communication conflict problem in a terminal. Another method for capability exchange performed by a core network includes: exchanging, with a base station, capability information for solving a multi-card communication conflict problem in a terminal. A method for exchange triggering performed by a terminal includes: in response to there being a multi-card communication conflict, sending a multi-card communication conflict problem to at least one of a base station and a core network, so as to trigger that capability information of the base station for solving the multi-card communication conflict is exchanged with the core network, or capability information of the core network for solving the multi-card communication conflict is exchanged with the base station.
