    Abstract: Examples provide an apparatus for instantiating a virtualised part of a next generation Node B, gNB, comprising a Network Functions Virtualisation Orchestrator, operable to carry out any one or more tasks including on-boarding an VNF package, on-boarding a PNF Descriptor on-boarding a Network Service Descriptor, enabling the VNF package, enabling the Network Service Descriptor, and sending appropriate responses to a Network Manager. Examples also provide corresponding methods.

    Abstract: A network management function (NMF) is configured to instantiate a network service (NS), update a NS, and/or establish a relation between a virtualized network function (VNF) instance and a physical network function (PNF) instance. The NMF may instantiate, for example, a NS including a new VNF that is part of a base station or a g Node B (gNB), a NS including a PNF that is part of the gNB, or a NS that includes a PNF and a new VNF that form a gNB. The NMF may also, for example, update a NS to add a VNF instance to a NS that already includes a PNF instance to form a gNB, or update a NS to add a PNF instance to a NS that already includes a VNF instance to form a gNB.

    Abstract: An apparatus of a Virtualized Network Function Manager (VNFM) comprises one or more processors to receive one or more performance measurements related to a virtual network interface that are collected for a virtual compute instance from a Virtualized Infrastructure Manager (VIM) in a collection interval, to map a measured object of the one or more performance measurements from the virtual compute instance to a Virtual Network Function (VNF) and/or VNF component (VNFC) instance, and to map the virtual network interface to a connection point (CP) associated with the VNF or VNFC instance, to generate one or more performance measurements related the CP for the VNF or VNFC instance. The one or more performance measurements related the CP for the VNF or VNFC instance are to be reported to an Element Manager (EM) or to a Network Function Virtualization Orchestrator (NFVO), or a combination thereof.

    Abstract: Techniques for generating and communicating performance measurements related to virtualized resources (VRs) are discussed. A first set of embodiments discusses relate to generating and communicating 3GPP NF performance measurements related to VR. A second set of embodiments relate to generating and communication VR-related performance measurements over specific reference points (e.g., Ve-Vnfm-em, Or-Vnfm, Or-Vi, Os-Ma-nfvo, etc.) of a management architecture for network function virtualization (NFV).

    Abstract: There is provided an apparatus for self-optimization of a Network Slice Instance, NSI, comprising network slice related management functions comprising one or more of: a Network Slice Management Function, NSMF, operable to monitor a performance of a Network Slice Instance in use, and evaluate whether the Network Slice Instance meets a received set of Network Slice requirements, wherein the received set of Network Slice requirements are received from a Service Management Function, SMF, and/or an Operator's target for performance of the Network Slice Instance; and a Network Slice Subnet Management Function, in communication with the Network Slice Management Function, and operable to modify a Network Slice SubNet Instance, NSSI, for use in the Network Slice Instance in use in order to meet the received Network Slice requirements. There is also provided a (computer implemented) method for self-optimization of a Network Slice Instance.

    Abstract: An element manager (EM) of a virtualized network for a wireless communication system processes a suspend measurement job request received from a network manager (NM). The request is to suspend a measurement job to provide network function (NF) performance measurements related to a virtualized resource (VR). In response to the suspend measurement job request, the EM stops reports reporting measurement result data for the measurement job and determines whether to instruct a virtualized network function manager (VNFM) to delete one or more performance management (PM) jobs used to support the measurement job. The EM then generates a suspend measurement job response to indicate to the NM a result of the request to suspend the measurement job.
