Policy Orchestration Framework for Multi-Access Network Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current policy management methods in mobile networks lack end-to-end visibility and top-to-bottom policy orchestration, limiting their ability to effectively manage complex network architectures and apply policies across multiple service levels.
Innovation Solution
A policy orchestration framework that provides an end-to-end view between frontend and backend networks, coordinating policy decisions through Push and Pull messages, and utilizing a Policy Orchestrator with a processor and memory to manage network services across multiple layers, ensuring comprehensive and adaptive policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current policy management methods are used, then specific network scenarios can be managed, but end-to-end visibility and top-to-bottom policy orchestration are not provided
Solution Approach 1:
The patent segments the network into frontend and backend domains with distinct policy management functions. The frontend policy management handles access and session policies, while the backend policy management handles service and resource policies. This segmentation allows each domain to maintain visibility within its scope while reducing overall system complexity through modular design.
Solution Approach 2:
The patent introduces a policy orchestration function as an intermediary that coordinates between frontend and backend policy management systems. This mediator enables end-to-end visibility by translating and synchronizing policy decisions across domain boundaries without requiring direct complex interactions between all components.
2Adaptability or versatility
If policy management is limited to specific scenarios, then implementation is simpler, but adaptability to complex network architectures and multiple service levels is reduced
Solution Approach 1:
The patent creates a universal policy management framework where the frontend and backend policy management systems can handle multiple types of policies (access, session, service, resource) through standardized interfaces. This multi-functional design enables the system to adapt to complex network architectures and various service levels without requiring separate specialized systems for each scenario.
Solution Approach 2:
The patent implements dynamic policy orchestration where policy decisions can be made at appropriate levels (frontend or backend) based on the specific scenario and service requirements. The system dynamically routes policy management tasks to the most suitable domain, enabling adaptability to changing network conditions and service demands while maintaining manageable complexity through clear governance rules.

AI summary
A Policy Orchestration Framework to support end-to-end (E2E) multi access network policy architecture with top-to-bottom policy orchestration. A frontend network is provided having a first plurality of layers supporting network services. A backend network is provided having a second plurality of layers supporting network services. A policy orchestration provides an end-to-end view between the frontend network and the backend network. The policy orchestrator coordinates end-to-end policy decisions for the first plurality of layers of the frontend and for the second plurality of layers of the backend. Intercommunications between the first plurality of layers and between the second plurality of layers uses Push Messages and Pull messages between the first plurality of layers and between the second plurality of layers.
