  • Patent number: 11785480
    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.

  • Patent number: 11765608
    Abstract: An apparatus of a management service equipment includes processing circuitry. To configure the management service equipment for E2E performance measurements in a 5G network with a plurality of network functions (NFs), the processing circuitry is to decode RAN latency received from a RAN within the 5G network. The RAN latency is associated with transmission of an Internet protocol (IP) packet between a UE and a data network (DN) via the RAN. A user plane function (UPF) latency associated with communication of the IP packet between the RAN and a UPF within the 5G network is determined. A DN latency associated with communication of the IP packet between the UPF and the DN is determined. An E2E performance measurement calculation is performed to determine an E2E latency associated with communicating the IP packet between the UE and the DN based on the RAN latency, the UPF latency, and the DN latency.

  • Patent number: 11722357
    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.

  • Patent number: 11709737
    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: 11689941
    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.

  • Publication number: 20230189006
    Abstract: Systems and methods for orchestration and configuration of end-to-end network slices across a 3GPP core network and ORAN are described. The network includes a NSMF that receives an AllocateNSI operation with attributes to allocate an NSI. The AllocateNSI operation includes an attributeListIn parameter that specifies network slice properties in a ServiceProfile to be supported by the NSI. The NSMF determines that a new NSI is to be created rather than using an existing NSI and that the new NSI is to contain a NSSI (RAN) and a NSSI (CN). The NSMF communicates with a NSSMF (RAN) and NSSMF (CN) to create the new NSI. The new NSI includes an O-CU-CP, O-CU-UP and O-DU VNFs, and an O-RU PNF for the NSSI (RAN), and UPF, AMF, and SMF VNFs for the NSSI (CN).

  • Publication number: 20230141237
    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.
