Solution Overview

Problem

Current multi-card terminal devices face challenges in coordinating wireless processing resources, particularly when multiple SIM cards need to share limited hardware resources, leading to difficulties in simultaneously supporting Dual Connectivity (DC) and Carrier Aggregation (CA) functions.

Innovation Solution

A method is introduced where a terminal device sends a message to a network device to request the release or suspension of connections with DC or CA cells, allowing flexible resource allocation and management, enabling multiple SIM cards to share hardware resources effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple SIM cards share wireless processing resources in a multi-card terminal device, then resource sharing capability is improved, but coordination difficulty increases

Engineering Contradiction:

Improveresource sharing capabilityVSAvoidcoordination difficulty

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic connection control where the terminal device can flexibly establish, release, or suspend connections with different cell types (DC cells, CA cells, or both) based on real-time resource availability and service requirements. This dynamic adjustment mechanism allows the system to adapt to varying resource constraints while maintaining coordination capability through standardized control procedures.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If Dual Connectivity and Carrier Aggregation functions are simultaneously supported, then service capability is improved, but resource coordination difficulty increases

Engineering Contradiction:

Improveservice capabilityVSAvoidresource coordination difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the connection control into distinct types: DC connection control, CA connection control, and combined DC+CA connection control. This segmentation allows independent management of different connection modes, simplifying the coordination process while maintaining the ability to support multiple service functions simultaneously through structured control procedures.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If connection release or suspension is requested for DC/CA cells, then resource allocation flexibility is improved, but connection stability decreases

Engineering Contradiction:

Improveresource allocation flexibilityVSAvoidconnection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the terminal device sends connection control requests to the network device based on resource availability and service needs. The network device responds with appropriate instructions, creating a closed-loop control system that balances connection stability with resource allocation flexibility through continuous communication and adjustment.

Inventive Principle:

Principle #23Feedback
