    Abstract: A device to host a service producer in a 5G system (or 5G system architecture), a method to be performed at the device, and a non-transitory storage device storing instructions to be executed at the device. The method includes: decoding a request from a service consumer to manage one or more 5G quality of service (QoS) indicators (5QIs), each 5QI including a 5QI value and corresponding 5QI characteristics; configuring one or more network functions (NFs) of the 5GS with the 5QIs based on the request; and encoding for transmission to the service consumer a message including a result of managing the one or more 5QIs.

    Abstract: A method and system for generating performance measurements related to DL and UL packet delays through a NG-RAN are described. The NG-RAN receives GTP PDU monitoring packets from a UPF and, in response measures the DL delays of the packets to and UL delays from a UE. The NG-RAN determines the per 5QI and per S-NSSAI distribution of the DL and UL delays and sends the performance measurements to a service provider. The average DL and UL delays may also be provided to the service provider. The service provider is in the NG-RAN or a separate management system. For a network slice, service providers for different NG-RANs send the performance measurements to a network slice service provider, where the individual NG-RAN performance measurements are combined to provide both the average and distribution of the DL and UL delays in the network slice.

    Abstract: An apparatus and system for generating KPIs based on packet delay performance measurements through a NG-RAN or 5GC are described. Integrated average UL and DL delays in NG-RAN, gNB DU delays and e2e delays are determined for each sub-network, network slice subnet, and network slice, and for a gNB DU. An overall NR cell DU delay including air interface delay and delay within the NR cell DU, and an overall gNB-CU delay including F1 interface delay and delay within the gNB-CU-UP, are each independently weighted for each gNB and in each direction for the integrated delay KPI in the NG-RAN. The e2e delay KPIs are average UL or DL delays between a UPF and UE(s) for a network slice based on e2e delays for each N-3 and N9 interface weighted by number of packets or data volume of the interface for the corresponding direction.

    Abstract: Systems and methods of using a MDAS in a network management loop are described. The MDA is used to aid in analysis and rectification of coverage issues and resource utilization. The MDA prepares, processes and analyzes data related to the managed networks and services using AI and ML techniques, and provides analytics reports for root cause analysis of ongoing issues, prevention of potential issues and prediction of network or service demands. The analytics report contains the description of the issues or predictions and recommended actions to mitigate the issues. The MDA classifies and correlates the input data (current and historical data), learn and recognize the data patterns, and analyzes the data to derive inference, insight and predictions. The MDA returns an analytics report describing issues or predictions for NFs, subnetwork, NSSI, and/or NSI.

    Abstract: Systems and methods provide solutions to add a physical network function (PNF) instance to a network service (NS), modify PNF instances in an NS, and remove PNF instances from an NS. For example, a process may include sending an update NS request from the management function to a network functions virtualization orchestrator (NFVO) to update the NS instance, the update NS request comprising an NS instance identifier, an update type, and PNF information; receiving an update NS response from the NFVO, the update NS response comprising a lifecycle operation occurrence identifier corresponding to an NS lifecycle operation occurrence; receiving an NS Lifecycle Change notification from the NFVO, the NS Lifecycle Change notification indicating a start of an NS update; and receiving an NS identifier change notification from the NFVO, the NS identifier change notification indicating a result of the NS update.

    Abstract: Techniques discussed herein can facilitate edge computing in connection with a variety of deployment scenarios. Various embodiments can facilitate one or more of: deploying UPF(s) (User Plane Function(s)) to support edge computing; removing UPF(s) not needed for edge computing; deploying local DN(s) (Data Network(s)); E2E (Edge-to-Edge) OSS (Operations Support System) deployment scenarios; and providing RAN (Radio Access Network) condition data to support various applications (e.g., autonomous driving).
