    Abstract: An apparatus of a management service equipment includes processing circuitry. To configure the management service equipment for E2E performance measurements in a 5G network with a plurality of network functions (NFs), the processing circuitry is to decode RAN latency received from a RAN within the 5G network. The RAN latency is associated with transmission of an Internet protocol (IP) packet between a UE and a data network (DN) via the RAN. A user plane function (UPF) latency associated with communication of the IP packet between the RAN and a UPF within the 5G network is determined. A DN latency associated with communication of the IP packet between the UPF and the DN is determined. An E2E performance measurement calculation is performed to determine an E2E latency associated with communicating the IP packet between the UE and the DN based on the RAN latency, the UPF latency, and the DN latency.

    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: Devices and methods of providing performance measurements (PMs) for Network Function Virtualization are generally described. A Virtual Network Function (VNF) PM job is scheduled at a VNF and VNF PM data received in response. From the VNF PM data, it is determined that virtualized resource (VR) management may be a cause of poor VNF performance. A VR PM job is scheduled and results in VR PM data. The VR PM and VNF PM data are analyzed to determine whether to increase the VR at the VNF. If an increase is determined, a request for the increase is transmitted from an element manager to a VNF manager or the VNF PM and/or VR PM data are provided to a Network Manager (NM) for the NM to request the increase by a Network Function Virtualization Orchestrator (NFVO).

    Abstract: The present disclosure relates to methods and systems for carrying out performance measurement monitoring. Specifically, a consumer seeking performance measurement monitoring transmits a request to a management service producer that includes the parameters of the monitoring, such as the type of data to be monitored, a granularity period and one or more threshold values. In response, the management service producer communicates with a network function to carry out the monitoring. In particular, for each granularity period, a monitoring value is initialized. Then, either at the end of the granularity period or at intervals throughout the granularity period, the monitoring value is measured. If, at the time of measurement, the measurement value exceeds any one of the threshold values, a notification is transmitted to the consumer. Otherwise, monitoring continues for the remainder of the granularity period and/or is repeated for subsequent granularity periods.

    Abstract: Systems and methods of managing creation and configuration for 5G networks, NFs and NSSIs are provided. An instantiation or configuration request received from a managed entity respectively instantiates or configures the appropriate element. For NF instantiation, when the NF has a virtualized part to be instantiated by a VNF, interaction with an NFV MANO system instantiates the VNF is followed by NF instantiation notification and MOI creation for the NF. For NF configuration, the NF is configured and notification provided thereof. For network instantiation, after reception of a network creation request, interaction with the system to instantiate a NS that realizes the network is followed by determination that a new VNF associated with the NS has been instantiated, creation of a NF (constituting the network) MOI is realized by the new VNF, and NF configuration. For NSSI creation, a NF constituting the NSSI is created and configured.
