Solution Overview

Problem

Conventional mobile terminal technologies experience communication interruptions and delays when switching between private communication networks and telecommunications carrier communication networks, leading to delays in data acquisition during handover or roaming.

Innovation Solution

A mobile terminal that simultaneously connects to multiple wireless networks, receives data regarding its movement from these networks, and executes only the first received data, using time-series information such as timestamps or sequence numbers to manage data execution without duplication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mobile terminal switches between private communication network and telecommunications carrier communication network, then network mobility is enabled, but communication interruption occurs causing delay in data acquisition

Engineering Contradiction:

Improvenetwork mobilityVSAvoiddata acquisition delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mobile terminal establishes connection with the destination network before disconnecting from the source network. The connection management unit maintains connections with multiple networks simultaneously during handover, allowing data transmission to begin immediately when the destination connection is ready, eliminating the traditional sequential switch-over delay

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous data transmission during network handover by keeping multiple network connections active simultaneously. The connection management unit ensures that data flow continues uninterrupted by routing through the destination network as soon as it becomes available, while the source network connection remains active until completely transitioned

Inventive Principle:

Principle #20Continuity of useful action

2Loss of time

If the mobile terminal connects to multiple wireless networks simultaneously, then data acquisition delay is reduced, but device complexity increases

Engineering Contradiction:

Improvedata acquisition delayVSAvoidconnection management complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The connection management unit acts as an intermediary that abstracts and simplifies the complexity of managing multiple network connections. It handles the simultaneous maintenance and switching between networks, presenting a simplified interface to the upper layers while managing the complex low-level connection details

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent combines multiple network connection management functions into a single integrated connection management unit. This unified structure manages simultaneous connections to multiple networks, handling data routing, connection establishment, and teardown operations through a consolidated mechanism rather than separate independent managers

Inventive Principle:

Principle #5Merging (Combining)
