Abstract: A control device configured to receive a service request that comprises a request for a resource associated with a network function or a network service in the communication system, obtain a descriptor based on the service request, derive a metadata of a service availability level from the descriptor, obtain a commissioning value, wherein the commissioning value is associated with requirements for a service, map the commissioning value with the metadata of the service availability level, derive the service availability level for the resource associated with the network function or the network service based on the mapped commissioning value with the metadata of the service availability level. A corresponding resource manager derives an assigned resource corresponding to the resource associated with the network function or the network service and the assigned resource fulfills the derived service availability and reliability requirement for the resource.

Abstract: Embodiments provide a software modification initiation method. The method can include receiving, by a VNFM, a VNF LCM request sent by an NFVO. The VNF LCM request may include an instance identifier of a VNF instance of to-be-modified first-version VNF software. The method can include determining, by the VNFM, that a type of the VNF LCM request indicates a software modification operation, and obtaining metadata according to the VNF LCM request. The metadata may include a version identifier of the first-version VNF software and a software modification type. The method can include determining, by the VNFM, a first VNF instance of the first-version VNF software based on the instance identifier of the VNF instance of the to-be-modified first-version VNF software. The method can also include initiating, by the VNFM, a software modification operation for the first VNF instance of the first-version VNF software based on the software modification type.

Abstract: A software upgrade method and system which relate to the field of communications technologies. The method is applied to an evolved core packet (EPC) system. The EPC system includes a system manager, a traffic decider, a first service server, and a second service server, and the first service server and the second service server are installed with service software of a first version. As a result, service continuity and stability of the EPC system are ensured.

Abstract: This application provides a method for managing a service in an NFV architecture, and an apparatus. The method includes: generating, by a first network element after receiving a network function virtualization NFV resource change notification sent by a virtualized infrastructure manager VIM, first constraint information used to modify NFVI software and/or hardware; and sending, by the first network element, a first notification message to the VIM, where the first notification message carries the first constraint information, and the first constraint information is used by the VIM to modify NFVI software and/or hardware based on the first constraint information.
