Virtual OAM Manager for Multi-Vendor VNF Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management systems, such as NMS/OSS/BSS, are unable to effectively manage various types of VNF network elements from different manufacturers within a virtualized network, limiting flexibility and compatibility.
Innovation Solution
A method and apparatus for deploying virtual operation, administration, and maintenance (V-OAM) that obtains customized information to define attributes and deploy V-OAM capable of managing multiple types of VNF network elements, including network management function configuration, interface definitions, resource requirements, and virtualization manners, allowing for dynamic management and scaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional NMS/OSS/BSS systems are used for network management, then management of specific hardware network elements is achieved, but the ability to manage various types of VNF network elements from different manufacturers is lost
Solution Approach 1:
The patent applies virtualization by creating a virtual copy of the OAM system (V-OAM) that can manage virtualized network functions. The V-OAM manager virtualizes OAM capabilities to match VNF requirements, enabling management of multiple VNF types without requiring separate physical management systems for each. This virtual copying approach allows the management system to adapt to different VNF manufacturers and types while maintaining a unified management architecture.
Solution Approach 2:
The V-OAM manager is designed with multi-functional capabilities to manage various types of VNF network elements from different manufacturers. By virtualizing OAM functions and creating a universal management interface, the system can handle diverse VNF types (e.g., EPC, 5G, Wi-Fi) through a single management platform, eliminating the need for manufacturer-specific management systems.
2Productivity
If virtualized network functions are deployed to improve flexibility and reduce costs, then hardware investment is reduced, but the ability to effectively manage and orchestrate these virtualized elements is compromised
Solution Approach 1:
The V-OAM manager acts as an intermediary between the NFV orchestration system and the virtualized network functions. It receives deployment information from the NFV system, processes it through virtualized OAM capabilities, and manages the VNFs accordingly. This intermediary layer ensures that virtualized network elements can be effectively managed and orchestrated while maintaining the flexibility and cost benefits of virtualization.
Solution Approach 2:
The system dynamically adjusts OAM parameters and capabilities based on the specific VNF deployment requirements. By changing OAM parameters to match different VNF types and deployment scenarios, the system maintains effective management capability across diverse virtualized network functions while preserving the productivity gains from virtualization.
3Ease of operation
If manufacturer-specific management systems are used for each VNF type, then detailed control is achieved, but system integration and interoperability are reduced
Solution Approach 1:
The patent segments OAM capabilities into virtualized functional units that can be independently configured and assigned to different VNF types. The V-OAM manager divides comprehensive OAM functions into manageable segments that can be selectively activated based on VNF requirements, enabling detailed control of specific VNFs while maintaining overall system integration through a unified management framework.

AI summary
A method for deploying virtual operation, administration and maintenance includes obtaining customized information of virtual operation, administration and maintenance (V-OAM) that needs to be deployed, where the customized information defines an attribute of the V-OAM, and deploying, on a virtualized network according to the customized information, the V-OAM that is capable of managing at least one type of VNF network element. The V-OAM is deployed on the virtualized network.
