Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Network slices created by communication operators may not necessarily satisfy the desired communication conditions of user equipment, leading to suboptimal communication performance.

Innovation Solution

User equipment decides the communication conditions required for a network slice and sends a creation request to the core network apparatus, allowing for the creation of a network slice that meets these conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If network slices are preconfigured by communication operators, then network management and control is simplified, but the communication conditions may not satisfy user equipment requirements

Engineering Contradiction:

Improvenetwork managementVSAvoidcommunication condition satisfaction

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The user equipment autonomously decides communication conditions and sends creation requests to the core network apparatus, enabling self-service for network slice creation. This resolves the contradiction by allowing UEs to self-determine suitable network slices without operator intervention, improving adaptability while maintaining operational simplicity through automated processes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of operators configuring slices and UEs selecting them, the invention inverts the process: UEs decide communication conditions and request slice creation. This role reversal enables UEs to obtain slices that truly meet their requirements while the core network apparatus handles the creation automatically, resolving the contradiction between ease of management and adaptability.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If user equipment autonomously decides communication conditions and requests slice creation, then communication performance is optimized, but signaling overhead and processing complexity increases

Engineering Contradiction:

Improvecommunication performanceVSAvoidsignaling processing

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The creation request message serves multiple functions: it conveys communication conditions, triggers network slice creation, and establishes the slice simultaneously. This multi-functionality reduces signaling overhead and processing complexity while enabling UEs to obtain optimized network slices for their specific requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention combines the communication condition decision-making, slice selection, and slice creation request into a single integrated process. The user equipment decides communication conditions and includes them directly in the creation request message, merging multiple steps into one operation. This reduces signaling overhead and processing complexity while ensuring communication performance optimization.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

According to an aspect, a communication control method includes deciding, at a user equipment, a communication condition to be satisfied by a network slice desired by the user equipment, and transmitting, at the user equipment, a creation request to a core network apparatus, the creation request being a message requesting to create the network slice and including information indicating the communication condition.
