    摘要： 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.

    摘要： An apparatus and system of collecting and reporting measurements for an Edge Application Server and 5th generation core network (5GC) network functions (NFs) that impact EAS performance are described. An application service provider (ASP) receives EAS performance measurements from edge computing service provider (ECSP) management system. The ECSP management system receives from the PLMN management system performance measurements from the 5GC NF that impact edge computing applications. The measurements are used to evaluate the end-to-end EAS performance, and determine actions to mitigate any issues based thereon.

    摘要： 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.

    摘要： A system, devices and procedures for providing QoS monitoring in a 5G network are described. The QoS monitoring is per QoS flow per UE or GTP-U path QoS monitoring. A SMF sends a request to a UPF and NG-RAN to report UL/DL packet delay and RTT between the UPF and a UE or an N3 and N9 interface, along with thresholds for reporting the measurements. The UPF sends a report containing the measurements when the threshold is met. The delays include average, minimum and maximum packet delays. The request also indicates a state of QoS monitoring, S-NSSAI and 5QI to monitor, whether event-based/periodic/session release-based QoS monitoring reporting per QoS flow per UE is supported, minimum waiting time between consecutive reports for event-triggered QoS monitoring reporting, and a period to report the measured packet delay.

    摘要： Systems and methods of providing performance measurements are described. The performance measurements reflect the performance of NF service management, PFD management, UE policy association, QoS flow release and handovers. Raw performance data is collected from one or more NFs and then measurement data results are provided to an NF measurement consumer. The measurement data results is used to diagnose ongoing issues impacting the performance of the mobile network and predict any potential issues.

    摘要： 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.

    摘要： An apparatus and method for CM, PM and FM of LWA and LWIP are described. An NM sends a management request to an EM for management of an IOC instance for LWA or LWIP. The EM manages the IOC instance based on the request and returns a response to the request. The response indicates a result of the request or a result of management of the IOC instance. The EM collects, from the network functions, performance measurements and alarms related to the LWA or LWIP. The collected information is provided to the NM. The NM and EM take an action based on the collected information.
