    Abstract: Embodiments of a Network Manager (NM), a (NFVO), and methods of communication are disclosed herein. The NM may transfer, to the NFVO, an update NS request message to update the NS instance based on the new NSD. The NM may encode the update NS request message to include: an nsInstanceID parameter that identifies the NS instance, and an updateType parameter that indicates a type of update for the NS instance. One value of “AssocPnfWithPnfProfile” for the updateType parameter may indicate a request to associate the PNF of the NS instance with a new or updated PNF profile indicated by the new NSD. Another value of “AssocVnfWithVnfProfile” for the updateType parameter may indicate a request to associate the VNF of the NS instance with a new or updated VNF profile indicated by the new NSD.

    Abstract: Systems and methods of performance management over a life cycle is provided. A measurement job control service producer receives, from an authorized consumer, a request to consume a measurement job control service. The request is analyzed, appropriate action is taken to satisfy the request and a response indicating the request result is generated. A request is to create or terminate a measurement job to collect the performance data for a NF, NSSI, NSI, or network. To create a job, the producer checks if the job can be supported by an existing job, creates the job if no such existing job exists, and otherwise responds that the job can be supported by the existing job. To terminate a job, the producer checks if the job is serving other consumers, terminates the job if other consumers are not being served, and otherwise responds that the job is currently serving other consumers.

    Abstract: This disclosure describes systems, methods, and devices for performing performance measurements for one-way uplink packet delay in wireless communications. An apparatus of a Service Based Management Architecture (SBMA) Management Service (MnS) Producer may identify performance measurements, received from a network function (NF) of a 5th Generation (5G) wireless network, indicative of uplink packet delay between a user equipment (UE) and a protocol data unit (PDU) session anchor (PSA) user plane function (UPF) of the 5G wireless network; detect whether the performance measurements indicate that the uplink packet delay includes an uplink PDCP delay occurred in the UE (D1); and generate performance metrics for the NF using the performance measurements.

    Abstract: Systems and methods of providing performance data streaming procedures are described. A MnS producer for measurement control receives a request to start or stop measurement collection indicating the measurements are reported by streaming, configures a NF to respectively start or stop collection of measurements and provides an indication of a result of starting or stopping the measurement collection. A MnS producer for performance data streaming, in response to reception of a request to set up streaming information sends a request to establish, add, or update a streaming connection for performance data streaming and receives an indication of a result of the request. In response to reception of a request to terminate the streaming, the MnS producer for performance data sends a request to terminate the streaming connection, or delete or update the stream information dependent on the functionality of the connection and the streams of the connection.

    Abstract: Systems and methods of re-configuring PCI values for a NR cell and performing mobility robustness optimization are described. To reconfigure the PCI values. The NRM data and the PCI of candidate cells measurements are analyzed to detect a potential PCI collision or PCI confusion among NR cells. In response to detection of the potential PCI collision or confusion, a new PCI value for at least one NR cell is determined and instructions to re-configure the at least one NR cell with the new PCI value are sent to a producer of provisioning MnS. For MRO, a NF provisioning MnS with modifyMOIAttributes operation to configure MRO targets for an MRO function and to enable the MRO function for a NR cell are consumed, as is a performance assurance MnS with a notifyFileReady or reportStreamData operation to collect MRO-related performance measurements. The measurements are analyzed to evaluate MRO performance.

    Abstract: Systems and methods of supporting RACH optimization and monitoring of UP packet delay performance are described. During RACH optimization, a NF provisioning MnS with modify MOIAttributes operation to configure targets for RACH optimization and a NF provisioning MnS with modifyMOIAttributes operation are separately consumed to enable a RACH optimization function for a NR cell. After this, a performance assurance MnS with notifyFileReady or reportStreamData operation is consumed to collect RACH optimization-related measurements for the NR cell and RACH performance data of the RACH optimization-related measurements analyzed to evaluate RACH optimization performance for the NR cell. During monitoring of UP packet delay performance, raw performance measurements related to UP packet delay based on at least one of NG-RAN measurement results or time stamps in GTP packets are obtained from a NG-RAN or UPF, UP packet delay performance measurements are generated. UP packet delay performance could be optimized based on the performance measurements.

    Abstract: Various embodiments herein provide techniques for management data analytics (MDA) for a wireless cellular network. The MDAS producer receives the raw data, classifies and analyses the raw data to generate the analytics output. The MDA process may be supported by machine learning techniques, and performed by a MDA service producer and assisted by a MDA service consumer. For example, the MDA service producer may receive training data from the MDA service consumer, and train a machine learning model based on the training data. The MDA service producer may apply the trained machine learning model to the raw data that are associated with network functions (e.g., self-organizing network (SON) functions) to generate output data that indicates a conflict between the network functions and a recommended action to address the conflict. Other embodiments may be described and claimed.
