Solution Overview

Problem

In communication networks, data service tasks face transmission continuity issues due to cell handovers, as preconfigured routing information becomes invalid when a terminal apparatus changes network apparatuses, leading to potential data loss.

Innovation Solution

A communication method and apparatus that involves a data control apparatus determining and transmitting routing information to ensure continuity by identifying next-hop data processing apparatuses after a cell handover, utilizing identification information of data pipelines, and coordinating data transmission between source and target network apparatuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If preconfigured routing information is used for data service task transmission, then data transmission efficiency is improved, but transmission continuity cannot be ensured when terminal apparatus performs cell handover

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidtransmission continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The routing information is transformed from a static preconfigured state to a dynamic state that can be updated during cell handover. The data control apparatus receives first information from the target network apparatus and sends second information to update the routing information, allowing the system to adapt to changing network conditions while maintaining both transmission efficiency and continuity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If terminal apparatus performs cell handover between network apparatuses, then mobility and adaptability are improved, but preconfigured routing information becomes invalid

Engineering Contradiction:
Improveterminal mobilityVSAvoidrouting information validity
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The data control apparatus is pre-configured to handle routing updates during cell handover. When the terminal apparatus performs handover, the data control apparatus proactively receives first information from the target network apparatus and sends updated second information before data transmission is affected, ensuring routing information remains valid throughout the handover process.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If routing information is updated during cell handover, then transmission continuity is maintained, but system complexity increases

Engineering Contradiction:
Improvetransmission continuityVSAvoidrouting update mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The data control apparatus serves as an intermediary between the target network apparatus and the data service task routing. It receives first information from the target network apparatus, processes the routing update, and sends second information to implement the update. This intermediary approach maintains transmission continuity while centralizing the complexity in a dedicated component rather than distributing it across multiple elements.

Inventive Principle:
Principle #24Intermediary (Mediator)
