Solution Overview

Problem

End-to-end Quality of Service (QoS) metrics in wireless networks are impacted by the performance of both the radio access network (RAN) and the core network, which often operate independently and lack effective communication, leading to degraded performance even if one component is within acceptable thresholds.

Innovation Solution

Implementing an O-RAN/5GC Intercommunication Function (OICF) to facilitate communication between the RAN and the core network, allowing for the exchange of analytics and configuration information to adjust parameters and maintain end-to-end QoS metrics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the RAN and core network operate independently without communication, then each network component can be managed and optimized separately, but the end-to-end QoS metrics deteriorate because performance issues in one component cannot be addressed by the other

Engineering Contradiction:
Improveend-to-end QoS metricsVSAvoidnetwork communication architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary communication mechanism between the RAN and core network that enables them to share performance information and coordinate QoS management. This intermediary layer allows independent networks to collaborate on end-to-end QoS without requiring deep integration, thus improving reliability while limiting complexity increase.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the RAN adjusts parameters to compensate for core network performance issues, then end-to-end QoS can be maintained, but the RAN operation complexity increases

Engineering Contradiction:
Improveend-to-end QoS metricsVSAvoidRAN parameter management
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the RAN receives performance information from the core network and automatically adjusts its parameters in response. This feedback loop enables the RAN to compensate for core network issues and maintain end-to-end QoS, with the complexity of parameter management handled by automated algorithms rather than manual operations.

Inventive Principle:
Principle #23Feedback

3Reliability

If the core network and RAN exchange analytics information, then coordinated QoS management is achieved, but information security risks increase

Engineering Contradiction:
Improveend-to-end QoS metricsVSAvoidinformation security exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements selective information sharing where only specific analytics data necessary for QoS management is exchanged between the RAN and core network, rather than all possible information. This local quality approach ensures that sensitive information remains protected while still enabling coordinated QoS management through targeted data exchange.

Inventive Principle:
Principle #3Local quality

AI summary

A system described herein may register a particular Service-Based Interface (“SBI”) with a core network (e.g., a Fifth Generation core (“5GC”)). The core network may maintain information associating the system with the particular SBI. The system may request core network information, associated with the core network, from the core network. The core network may provide the requested core network information to the device via the registered particular SBI. The system may provide the core network information, received via the particular SBI, to a radio access network (“RAN”), such as an Open-RAN (“O-RAN”), which may modify RAN configuration parameters based on the provided core network information. The system may also receive requests for RAN information from the core network via the SBI, may obtain the information from one or more elements of the RAN, and may provide the requested RAN information to the core network via the SBI.
