  • Publication number: 20220394785
    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.

  • Publication number: 20220330035
    Abstract: Network Functions Virtualization (NFV) abstracts network functions, allowing them to be installed, controlled, and manipulated by software running on standardized compute nodes such as cloud computing platform rather than on dedicated hardware. In a 5G mobile communications network, the base station or gNB may be split into virtualized and non-virtualized network functions (NFs). Described herein are systems and methods for managing such gNBs within the NFV framework.

  • Publication number: 20220276933
    Abstract: Techniques for identifying and remedying performance issues of Virtualized Network Functions (VNFs) are discussed. An example method includes outputting a request to a network Element Manager (EM) to create a Virtualized Network Function (VNF) Performance Measurement (PM) job to collect VNF PM data from a VNF and receiving a set of VNF PM data associated with the VNF from the EM. The set of VNF PM data is processed associated with the VNF. A request to the EM is output to create a Virtualization Resource (VR) PM job to collect, through a VNF Manager (VNFM) and a virtualized infrastructure manager (VIM), VR PM data from a VR used by the VNF. Then a set of VR PM data is received from the EM and processed.

  • Patent number: 11418383
    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.

  • Publication number: 20220174521
    Abstract: In an example method, a management service (MnS) producer sends a first request to establish a connection for streaming performance data regarding a wireless communications network to a MnS consumer. The MnS producer receives a first response from the MnS consumer confirming establishment of the connection, and streams one or more units of performance data to the MnS consumer sequentially using the connection. The one or more units include one or more performance metrics regarding the wireless communications network. The MnS producer sends a second request to the MnS consumer to terminate the connection, and receives a second response from the MnS consumer confirming termination of the connection.

  • Publication number: 20220141751
    Abstract: Some embodiments of this disclosure include apparatuses and methods for identifying performance measurements for registration and handovers for user equipment (UE) and wireless network nodes. A service producer system may register a first wireless communication connection with a first UE using one or more access and mobility management functions (AMFs). The service producer system may monitor registration measurements corresponding to this registration, perform a handover for the first UE using the one or more AMFs, and monitor mobility measurements corresponding to the handover. The service producer system may select a node for a second wireless communication connection corresponding to a second UE based on the registration measurements and mobility measurements and transmit an indication of the selected node to the second UE.

  • Publication number: 20220141738
    Abstract: Some embodiments of this disclosure include apparatuses and methods for applying mobility robustness optimization (MRO) and automatic network slice creation in 5G Self-Organizing Networks (SON). A network system may identify user equipment (UE) performing a handover from a first node to a second node. The network system may apply a MRO function to identify a target parameter corresponding to the handover. The network system may monitor connection measurements and/or radio link failure reports to identify the handover as failing to meet the target parameter. The network system may then modify the target parameter to facilitate the handover to the second node. For the automatic creation of a network slice instance (NSI), a network system may receive network slice specifications and apply the specifications to an automatic NSI creation function. The network system may instantiate network functions according to the automatic NSI creation function to create an NSI.
