Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current cell handover decisions in wireless communication networks based on UE measurement reports may not ensure service quality and can even reduce it, lacking a reliable basis for decision-making.

Innovation Solution

Implementing a communication method where access network elements utilize service quality analytics results from a data analytics network element to make informed handover decisions, considering both service quality and signal quality conditions, with optional priority information for different service types or channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cell handover decision is made based on UE measurement report, then handover can be performed, but service quality of UE cannot be ensured and may even be reduced

Engineering Contradiction:

Improveservice qualityVSAvoidhandover decision basis

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

A data analytics network element is introduced as an intermediary between the access network element and the handover decision process. This intermediary collects service quality data from multiple sources, performs analytics processing, and provides comprehensive handover decision basis to the access network element, thereby improving the reliability of handover decisions while ensuring service quality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements a feedback mechanism where the data analytics network element continuously monitors service quality indicators, analyzes the data, and feeds back handover recommendations to the access network element. This closed-loop feedback ensures that handover decisions are based on actual service quality conditions rather than just signal measurements.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If handover is performed based on signal quality threshold, then handover decision can be made, but it may not reflect actual service quality requirements

Engineering Contradiction:

Improvehandover decision makingVSAvoidservice quality assurance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system transforms the handover decision basis from simple signal quality parameters to comprehensive service quality parameters. The data analytics network element analyzes multiple service quality indicators (throughput, latency, packet loss, etc.) and converts them into actionable handover recommendations, enabling easier decision-making while ensuring service quality requirements are met.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The data analytics network element serves multiple functions: collecting data from various sources, analyzing service quality, generating handover recommendations, and providing decision basis to access network elements. This multi-functional approach simplifies the overall handover decision process while improving service quality assurance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

This application provides a communication method, a communication apparatus, a device, and a communication system. A data analytics network element determines a service quality analytics result for a target terminal device, and sends the service quality analytics result to an access network element. After receiving the service quality analytics result, the access network element may perform handover decision on the target terminal device based on the service quality analytics result.
