Solution Overview

Problem

Conventional wireless network handover techniques often result in the wasteful reservation of radio resources in cells that an end device does not ultimately enter, leading to inefficient use of network resources and potential latency issues, especially in scenarios requiring low latency like C-V2X and autonomous vehicles.

Innovation Solution

A wireless resources handover service that synchronizes end devices with the network to predict their mobility profile, allowing the network to pre-allocate resources only where the device will roam, using scheduler logic to determine optimal handover routes and resource allocation across MEC sites to maintain service continuity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If radio resources are reserved in all neighboring cells ahead of handover, then service continuity is maintained, but network resource waste increases

Engineering Contradiction:
Improveservice continuityVSAvoidnetwork resource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary actions by predicting the end device's mobility profile and pre-reserving resources only in cells that will be entered, rather than reserving resources in all neighboring cells. This maintains service continuity while avoiding resource waste in cells that won't be accessed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by making resource reservation cell-specific rather than universal. Resources are reserved locally only in the specific cells along the predicted mobility path, rather than uniformly across all neighboring cells, optimizing resource allocation based on actual need.

Inventive Principle:
Principle #3Local quality

2Reliability

If resources are pre-allocated in all neighboring cells, then handover reliability is improved, but resource allocation efficiency deteriorates

Engineering Contradiction:
Improvehandover reliabilityVSAvoidresource allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system calculates the end device's mobility profile in advance and performs preliminary resource allocation only in the specific cells that will be entered along the predicted path. This ensures handover reliability while improving resource allocation efficiency by avoiding allocation in cells that won't be accessed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameter of resource allocation from a static, uniform approach across all neighboring cells to a dynamic, selective approach based on predicted mobility parameters. This optimization improves resource allocation efficiency while maintaining handover reliability.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional handover techniques are used, then service continuity is maintained, but latency increases

Engineering Contradiction:
Improveservice continuityVSAvoidhandover latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary resource reservation based on predicted mobility profiles before handover is actually needed. This advance preparation reduces handover latency while maintaining service continuity, as resources are already in place when the end device arrives.

Inventive Principle:
Principle #10Preliminary action
