    Abstract: Techniques for instantiation and termination of virtualized network functions are described. In one embodiment, for example, an apparatus may comprise processing circuitry and computer-readable storage media having stored thereon instructions for execution by the processing circuitry to identify, based on a first message received from an integration reference point manager (IRPManager), a virtualized network function (VNF) instance to be terminated, send a VNF termination request to a virtualized network functions manager (VNFM) to request termination of the VNF instance, determine a VNF instance termination result for the VNF termination request based on a notification received from the VNFM, and send a second message to the IRPManager, the second message to indicate the VNF instance termination result. Other embodiments are described and claimed.

    Abstract: Systems and methods of managing PNF connectivity are provided. A NM determines to add to or remove external connectivity from a PNF and transmits a NS update request to a NFVO that contains an identifier of the NS instance to be updated, an indication of a type of update operation requested, and information of the PNF connectivity to be changed. A NS update response contains a lifecycle operation occurrence identifier identifying a NS lifecycle operation occurrence. Separate NS lifecycle change notification from the NFVO indicate that a NS update to change the connectivity of the PNF has started and a result of the change. The notifications include the lifecycle operation occurrence identifier.

    Abstract: Techniques discussed herein can facilitate one or more of improvements to Automatic Neighbor Relation(s) (ANR(s)) for cell(s) of a Radio Access Network (RAN), configuration of Physical-layer Cell Identifier(s) for cell(s) of the RAN, and/or end-to-end performance assurance for the RAN based on 5G QoS Identifier (5QI) targets and/or requirements. Various embodiments can employ one or more of the techniques discussed herein, for example, at a component or service of a Fifth Generation (5G) Core Network (5GC), a Third Generation Partnership Project (3GPP) Management System, or a node of a Radio Access Network (RAN).

    Abstract: Techniques discussed herein can facilitate EC (Edge Computing) in connection with 5GC (Fifth Generation Core Network) system architecture. Various embodiments can facilitate one or more of: (1) providing the location of one or more UPFs (User Plane Functions) associated with at least one AS (Application Server) to a non-3GPP (Third Generation Partnership Project) EC management system; (2) providing the location of at least one AS associated with one or more UPFs to a 3GPP management system; and/or (3) establishing a relation between one or more UPFs and at least one AS.

    Abstract: Examples provide an apparatus for instantiating a Network Service containing a Virtualised Network Function that is part of a Core Network, and a Virtualised Network Function that is part of a next generation Node B, gNB, comprising a Network Function Virtualisation Orchestrator, NFVO, operable to: receive a request to instantiate a new Network Service from a Network Manager; instantiate the Network Service containing the Virtualised Network Function that is part of the Core Network, and the Virtualised Network Function that is part of the gNB; and respond to the Network Manager indicating that the requested new Network Service has been instantiated. In other examples, there is provided a computer implemented method for instantiating a Network Service.

    Abstract: Techniques for identifying and remedying performance issues of Virtualized Network Functions (VNFs) are discussed. An example system includes processor(s) configured to: process VNF Performance Measurement (PM) data received from a network Element Manager (EM) for a VNF; determine whether the VNF has a negative performance issue based on the VNF PM data; request that the EM create a Virtualization Resource (VR) PM job associated with a VR of the VNF when the VNF has the negative performance issue; process VR PM data received from the EM; determine whether to restart the VNF based on the VR PM data and the VNF PM data; and request a network function virtualization orchestrator (NFVO) to restart the VNF based on a determination to restart the VR.

    Abstract: An apparatus of a management service producer comprises one or more processors to create a measurement job for one or more NFs, NSSIs, NSIs, networks or subnetworks by receiving a CreateMeasurementJob operation request for creating a measurement job for the one or more NFs, NSSIs, NSIs, networks or subnetworks from a consumer, checking if one or more new measurement types need to be collected for the one or more NFs or constituent NSSIs or constituent NFs, requesting the NFs or the management service producer of the constituent NSSIs or constituent NFs to collect the performance data when one or more new measurements types are to be collected for the one or more NFs or constituent NSSIs or constituent NFs. The management service producer allows the consumer to choose the reporting method from performance data file reporting and performance data streaming for the collected performance data in the CreateMeasurementJob operation request.
