Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If virtual network functions are implemented on off-the-shelf servers to increase flexibility and resource allocation capability, then adaptability and ease of operation are improved, but efficient use of computational resources becomes more difficult in complex network architectures

Engineering Contradiction:
Improveflexibility regarding resource provisioningVSAvoidcomplexity of resource allocation in complex network architectures
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a sharing profile as an intermediary mechanism that mediates between the virtual network function and multiple communication networks. The sharing profile contains sharing rules that automatically determine whether and how a VNF can be shared with other networks, eliminating the need for complex manual resource allocation decisions in multi-network environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sharing profile is designed as a universal mechanism that can be applied to any virtual network function across any number of communication networks. It provides a standardized approach for resource sharing that works consistently regardless of the specific network architecture or VNF type, simplifying resource management across diverse complex networks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If virtual network functions are shared across multiple communication networks to optimize resource usage, then productivity and resource efficiency are improved, but ensuring proper authorization and isolation between networks becomes more complex

Engineering Contradiction:
Improveresource usage efficiencyVSAvoidauthorization and isolation between networks
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The sharing profile acts as an intermediary authorization mechanism that sits between the virtual network function and requesting communication networks. It contains sharing rules that automatically enforce authorization decisions and isolation requirements, ensuring that resource sharing does not compromise network security or reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sharing profile is established in advance with predefined sharing rules that determine under what conditions a VNF can be shared. This preliminary configuration of authorization rules ensures that when sharing requests occur, the decisions are already determined and isolated, preventing security issues during dynamic resource allocation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If sharing profiles with sharing rules are established to control VNF sharing between networks, then reliability and authorization control are improved, but device complexity and management overhead increase

Engineering Contradiction:
Improveauthorization control for VNF sharingVSAvoidcomplexity of sharing profile management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sharing profile uses parameter-based sharing rules that can be configured with simple yes/no decisions or basic conditions. By changing the management approach from complex policy frameworks to parameter-based rules, the system achieves reliable authorization control while keeping the complexity of profile management tractable and manageable.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If virtual network functions are allocated dynamically to cope with load increases, then adaptability and responsiveness are improved, but efficient resource allocation in multi-network environments becomes more difficult

Engineering Contradiction:
Improveability to cope with dynamic load increaseVSAvoidcomplexity of resource allocation across interconnected networks
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sharing profile serves as an intermediary that automatically handles the complexity of resource allocation decisions across multiple networks. When load changes occur, the system can dynamically allocate VNFs to networks that have capacity, with the sharing profile automatically determining eligibility based on pre-configured sharing rules, thus maintaining adaptability without proportionally increasing allocation complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

According to one embodiment, a communication system is described comprising a network function virtualization orchestration system configured to provide a virtual network function for an application for a communication network and a virtual network function sharing management component configured to establish a sharing profile of the virtual network function, wherein the sharing profile specifies whether the virtual network function may be shared with another communication network. The network function virtualization orchestration system is configured to, upon a request from the other communication network for provision of a virtual network function, fulfil the request from the other communication network by sharing the provided virtual network function with the other communication network if the sharing profile specifies that the virtual network function may be shared with the other communication network.
