Solution Overview

Problem

Cloud-deployed base stations face challenges in managing and troubleshooting due to the association between virtual network functions (VNFs) and their associated base stations, particularly in distributed virtualized environments.

Innovation Solution

Implement a controller for telecommunications wireless base stations with virtualized entities, each having a dedicated virtual network interface stack that includes a virtual MAC address, VLAN, and logical IP address, allowing functional applications to be bound to physical network interfaces through these stacks, thereby managing and troubleshooting associations effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If virtual network functions are deployed in a distributed virtualized manner, then scalability and high-availability are improved, but management and troubleshooting complexity increases

Engineering Contradiction:

ImprovescalabilityVSAvoidmanagement complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the network interface functional applications into separate virtual network functions (VNFs), each bound to specific physical network interfaces. This segmentation enables independent deployment and management of VNFs while maintaining clear associations through binding relationships, thus improving scalability without proportionally increasing management complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces binding relationships as intermediary structures that connect virtual network functions to physical network interfaces. These binding relationships act as mediators that simplify management by providing explicit association mappings, making it easier to troubleshoot and manage the distributed virtualized environment

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If all network interface functional applications are bound to assigned physical network interfaces, then implementation simplicity is maintained, but flexibility and adaptability are reduced

Engineering Contradiction:

Improveimplementation simplicityVSAvoidflexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic binding relationships that allow virtual network functions to be associated with physical network interfaces in flexible configurations. The binding relationships can be established, modified, and removed dynamically, enabling the system to adapt to different deployment scenarios while maintaining implementation simplicity through standardized binding mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a universal binding relationship mechanism that can accommodate multiple virtual network functions bound to the same or different physical network interfaces. This multi-functional binding approach provides flexibility for various deployment configurations while maintaining a consistent and simple implementation framework

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If multiple base station deployments are hosted in cloud infrastructures, then resource utilization is improved, but association identification between VNFs and base stations becomes difficult

Engineering Contradiction:

Improveresource utilizationVSAvoidassociation identification

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent uses unique identifiers and binding relationship metadata as distinguishing markers (analogous to color changes) to clearly differentiate and identify associations between virtual network functions and base stations. Each binding relationship includes unique identification information that makes associations visible and traceable, preventing information loss in multi-tenant cloud environments

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent implements feedback mechanisms through binding relationship tracking and association identification. The system maintains records of binding relationships and provides feedback information about which VNFs are associated with which base stations, enabling effective resource management and troubleshooting in shared cloud infrastructures

Inventive Principle:

Principle #23Feedback
