Solution Overview

Problem

Current QoS mechanisms in 5G networks fail to meet the differentiated service quality of experience requirements for user equipments accessing the same service, leading to inefficient resource allocation and potential waste of communication resources, particularly in scenarios like public safety and disaster relief or enterprise campuses.

Innovation Solution

Implement a communication method that utilizes a radio access management controller and intelligent controller to dynamically adjust QoS based on UE group features, ensuring targeted service quality of experience by optimizing network elements and resources, and enabling direct signaling interactions between core network elements to meet specific UE requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If same QoS is allocated to all UEs accessing same service, then network resource allocation is simplified, but service quality of experience requirements for specified UEs cannot be met

Engineering Contradiction:
Improveservice quality of experience differentiationVSAvoidQoS allocation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by differentiating QoS treatment for specific UEs versus general UEs. The network device identifies specified UEs through first identification information and applies customized QoS parameters to them, while other UEs receive standard QoS allocation. This enables tailored service quality for critical users without overcomplicating the overall system.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the UE population into specified UEs (requiring differentiated QoS) and general UEs (receiving standard QoS). This segmentation is achieved through the network device receiving first identification information indicating specified UEs, then applying different QoS allocation strategies to each segment, resolving the contradiction between differentiation and complexity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If differentiated QoS is implemented for specified UEs, then service quality of experience requirements are met, but network resource allocation complexity increases

Engineering Contradiction:
Improveservice quality of experience guaranteeVSAvoidnetwork resource allocation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-identifying specified UEs through first identification information before QoS allocation. The network device receives this identification information in advance and prepares customized QoS parameters for specified UEs, ensuring reliable service quality guarantee without introducing complex real-time decision-making during resource allocation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses first identification information as an intermediary mechanism to bridge the gap between service quality requirements and resource allocation. This intermediary enables the network device to automatically identify and differentiate specified UEs without requiring complex analysis of each UE's service requirements, thus guaranteeing reliability while controlling complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of energy

If customized QoS parameters are allocated to specified UEs, then communication resource waste is reduced, but signaling interaction complexity between network elements increases

Engineering Contradiction:
Improvecommunication resource wasteVSAvoidsignaling interaction complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent extracts the identification of specified UEs as a separate function performed by the network device. By receiving first identification information that explicitly indicates which UEs are specified, the system separates the differentiation logic from the general resource allocation process, enabling efficient resource utilization without embedding complex differentiation logic throughout the entire signaling interaction framework.

Inventive Principle:
Principle #2Taking out (Extraction)
