28.5253GPPLife Cycle Management (LCM) for mobile networks that include virtualized network functionsRelease 17RequirementsTelecommunication managementTS

3GPP mobile network management standards incorporate the Life Cycle Management (LCM) provided by the ETSI NFV defined NFVO and VNFM functional blocks, facilitating the installation, dimensioning, layer 2 and 3 interconnection, healing and recovery of 3GPP-defined network functions that are virtualized.

Some requirements specified in TS 28.500 [2], TS 28.510 [11], TS 28.515 [12], TS 28.520 [7] and TS 28.525 specifications on telecommunication management for mobile networks that include virtualized network functions, are related to or using the LCM exposed by NFVO and VNFM functional blocks. The LCM operation requests, responses and notifications can carry parameters. In the context of the 3GPP mobile network management standards, the parameters used in the LCM operation requests, responses and notifications are not the 3GPP-defined network function parameters.
