Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If session management function derived core network assisted radio access network parameters are implemented, then network behavior optimization and UE activity prediction accuracy are improved, but system complexity and parameter management overhead increase

Engineering Contradiction:

Improvenetwork behavior optimizationVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a session management function as an intermediary component that derives core network assisted radio access network parameters. This intermediary layer processes and manages the complex parameter relationships, isolating the complexity from the core network and radio access network while providing optimized parameters for improved network behavior and UE activity prediction.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the parameter management functionality by separating session management parameters from radio access network parameters. The session management function derives and manages these parameters independently, allowing for specialized optimization without overwhelming the entire system with complexity.

Inventive Principle:

Principle #1Segmentation

2Use of energy by moving object

If session management function derived parameters are used to determine expected session activity behavior, then power savings and resource allocation efficiency are improved, but parameter storage and processing requirements increase

Engineering Contradiction:
