27、ated in the document. Introduction 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

28、 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 M

29、anagement 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 clarif

30、ies 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. ETSI ETSI TS 128 500 V14.1.0 (201

48、 implementation options for the entities of the 3GPP system include various technologies for virtualization. Network and service providers make use of different information in several different ways which also may vary from network to network and from time to time. Hence, entities of the 3GPP system

49、 that have been implemented with virtualization options should be managed in the same manner as entities implemented with non-virtualization options, to the extent possible. Virtualized 3GPP entities still require some underlying hardware resources. One of the NFV business objectives is that VNFs are procured independently from the underlying hardware resources. The underlying hardware resources are expected to be administered independently from the virtualized entities required for the 3GPP system.
