Solution Overview

Problem

The management of multi-connection between a terminal and multiple base stations poses a challenge, as user equipment needs to extend from using resources of one network node to using resources of two or more nodes, requiring a new connection management scheme to efficiently handle the increased complexity.

Innovation Solution

A method and system where a source base station controls the terminal to establish connections with other base stations by acquiring necessary information to generate a radio reconfiguration message, indicating the terminal to access additional cells, and updating the data transmission path through these base stations, ensuring seamless data transfer and resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the terminal uses resources of two or more network nodes simultaneously (dual-connection), then the throughput capacity and mobile properties are improved, but the complexity of connection management increases

Engineering Contradiction:
Improvethroughput capacityVSAvoidconnection management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the connection management function by introducing a source base station that coordinates the terminal's connections to multiple base stations. The source base station divides the management tasks by controlling the terminal to establish connections with target base stations and updating data transmission paths, thereby reducing the overall management complexity while enabling dual-connection for improved throughput capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The source base station acts as an intermediary between the terminal and multiple target base stations. It generates radio reconfiguration messages to control the terminal's connections and updates data transmission paths through these intermediated base stations, simplifying the coordination complexity inherent in multi-node resource utilization while maintaining improved throughput capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the terminal establishes connections with multiple base stations, then the resource utilization is improved, but the path management complexity increases

Engineering Contradiction:
Improveresource utilizationVSAvoidpath management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The source base station performs preliminary actions by pre-configuring radio reconfiguration messages that include information about target base stations and data transmission paths. This preliminary configuration enables the terminal to establish connections with multiple base stations efficiently, improving resource utilization while the source base station maintains path management control to reduce complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the source base station receives information from target base stations about connection status and updates the data transmission paths accordingly. This feedback loop enables adaptive path management that improves resource utilization across multiple base stations while maintaining manageable complexity through centralized control at the source base station.

Inventive Principle:
Principle #23Feedback
