Solution Overview

Problem

Existing wireless communication systems with multi-radio dual connectivity (MR-DC) face challenges in efficiently managing transceiver resources when multiple connections are active, leading to a need for coordinated release of connections to enable further connections or USIM operations without causing service interruptions.

Innovation Solution

A terminal device equipped with a processor and memory that transmits coordinated leave information to a network device, indicating the release of one of the two connections, allowing for the temporary or permanent suspension of transceiver resources, and facilitating bearer remapping or suspension based on network capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multi-radio dual connectivity is maintained with multiple simultaneous connections, then communication reliability and data throughput are improved, but transceiver resource availability deteriorates

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidtransceiver resource availability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic connection management where the terminal device can transition between dual connectivity and single connectivity modes based on operational needs. The coordinated leave mechanism allows the device to dynamically release one connection while maintaining the other, enabling flexible adaptation of transceiver resources without compromising overall communication reliability. This dynamic reconfiguration resolves the contradiction by making the system adaptable to varying resource requirements while maintaining connection stability.

2Area of stationary object

If transceiver resources are allocated to multiple simultaneous connections, then service coverage is improved, but resource utilization efficiency deteriorates

Engineering Contradiction:
Improveservice coverageVSAvoidresource utilization efficiency
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The patent extracts and releases specific transceiver resources from one connection through the coordinated leave mechanism when they are no longer needed for that particular connection. This allows the terminal device to free up resources (such as radio bearers, physical channels, and processing capabilities) while maintaining other active connections. The extracted resources can then be reallocated to accommodate additional USIM operations or optimize existing connections, thereby improving resource utilization efficiency without reducing service coverage.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If coordinated release of connections is implemented, then resource management flexibility is improved, but connection stability deteriorates

Engineering Contradiction:
Improveresource management flexibilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent employs preliminary action by implementing a coordinated leave mechanism that proactively manages connection release before resources become completely unavailable or conflicting operations arise. The terminal device can initiate coordinated leave procedures in advance to prepare for upcoming USIM operations or network reconfigurations. This preliminary resource release planning allows the system to maintain connection stability during transitions, as the release process is carefully orchestrated rather than abrupt, thereby balancing flexibility with stability.

Inventive Principle:
Principle #10Preliminary action
