Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal uses multiple SIM cards for communication, then the terminal can access multiple networks simultaneously, but communication conflicts occur between the SIM cards affecting communication effectiveness

Engineering Contradiction:
Improvemulti-network access capabilityVSAvoidcommunication effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces base station capability information as an intermediary mechanism. The first base station sends capability information to the second base station, which acts as a mediator to coordinate resource allocation and resolve conflicts between multiple SIM cards. This intermediary capability exchange enables the network to manage multi-SIM operations without direct terminal intervention, maintaining communication reliability while supporting multi-network access.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If base stations independently manage communication resources, then each base station can optimize its own resource allocation, but coordination between base stations is insufficient leading to unresolved communication conflicts

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidcommunication conflict resolution
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent merges the capability management of multiple base stations by establishing an information exchange mechanism. The first base station's capability information is combined with the second base station's resources through capability sending and receiving processes. This merging enables coordinated resource allocation across base stations, allowing them to work together as a unified system to resolve multi-SIM communication conflicts while maintaining individual resource optimization.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If capability information is exchanged between base stations, then coordination for solving communication conflicts is improved, but signaling overhead and system complexity increase

Engineering Contradiction:
Improvecommunication conflict resolution capabilityVSAvoidbase station coordination mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the essential capability information needed for conflict resolution from the complete base station configuration. Instead of exchanging all base station parameters, the system extracts and transmits only the relevant capability indicators (such as multi-SIM support capability, resource allocation capability). This extraction reduces signaling overhead and simplifies the coordination mechanism while maintaining the ability to resolve communication conflicts effectively.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present disclosure relates to a capability sending method and apparatus, and a capability receiving method and apparatus. The capability sending method is applicable to a first base station, and comprises: sending first capability information to a second base station, wherein the first capability information is used for indicating the capability of a first base station and/or a neighboring base station of the first base station to solve the problem of a multi-card communication conflict in a terminal. According to the present disclosure, a second base station can determine the capability of a first base station to solve the problem of a multi-card communication conflict in a terminal, and/or the second base station can determine the capability of a neighboring base station of the first base station to solve the problem of the multi-card communication conflict in the terminal, such that the second base station can cooperate with the first base station and/or the neighboring base station of the first base station to solve the problem of a communication conflict for the terminal more comprehensively.
