Abstract: An apparatus and system of adjusting network slice subnet instance (NSSI) resources in an open-radio access network (O-RAN) are described. The non-real time RAN Intelligent Controller (Non-RT RIC) framework of a Service Management and Orchestration (SMO), receives measurements from E2 nodes of a NSSI.

The Non-RT RIC framework sends a modify Managed Object Instance (MOI) operation to the E2 nodes to adjust the NSSI resources.

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.

Abstract: In an example computer-implemented method, a management module receives measurement data from one or more first network modules of a wireless communications network. The measurement data pertains to at least one of establishing one or more communications sessions on the wireless communications network by the one or more first network modules, or modifying one or more communications sessions on the wireless communications network by the one or more first network modules. The management module generates one or more performance metrics based on the measurement data, and transmits the one or more performance metrics to one or more second network modules of the wireless communications network.

Abstract: The present disclosure relates to methods and systems for carrying out performance measurement monitoring. Specifically, a consumer seeking performance measurement monitoring transmits a request to a management service producer that includes the parameters of the monitoring, such as the type of data to be monitored, a granularity period and one or more threshold values. In response, the management service producer communicates with a network function to carry out the monitoring. In particular, for each granularity period, a monitoring value is initialized. Then, either at the end of the granularity period or at intervals throughout the granularity period, the monitoring value is measured. If, at the time of measurement, the measurement value exceeds any one of the threshold values, a notification is transmitted to the consumer. Otherwise, monitoring continues for the remainder of the granularity period and/or is repeated for subsequent granularity periods.

Abstract: Systems and methods for orchestration and configuration of end-to-end network slices across a 3GPP core network and ORAN are described.

Abstract: 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.
