Traditionally, telecommunication equipment is provided as equipment with integrated software and hardware. Virtualization technologies decouple the software and hardware, and the network function software can be executed on COTS hardware.
The mobile network will be composed of virtualized network functions and non-virtualized network elements in the future. Virtualized network functions, like traditional non-virtualized network elements, need also to be managed.
Due to the decoupling of network function software and hardware, ETSI ISG NFV introduces the NFV Management and Orchestration architecture, which interacts with 3GPP network management system, to realize the management of virtualized network functions lifecycle and resource allocation. 3GPP specifies the management solution of mobile networks that include virtualized network functions and clarifies the relationship between 3GPP management architecture and ETSI ISG NFV Management and Orchestration architecture.
The present document specifies the management concept, requirements and architecture for mobile networks that include virtualized network functions.
The present document specifies the management concepts, the management requirements and use cases from operators' perspective for mobile networks that include virtualized network functions which can be part of EPC or IMS, and provides the management architecture for these mobile networks.
