    Abstract: Some embodiments of this disclosure include apparatuses and methods for applying mobility robustness optimization (MRO) and automatic network slice creation in 5G Self-Organizing Networks (SON). A network system may identify user equipment (UE) performing a handover from a first node to a second node. The network system may apply a MRO function to identify a target parameter corresponding to the handover. The network system may monitor connection measurements and/or radio link failure reports to identify the handover as failing to meet the target parameter. The network system may then modify the target parameter to facilitate the handover to the second node. For the automatic creation of a network slice instance (NSI), a network system may receive network slice specifications and apply the specifications to an automatic NSI creation function. The network system may instantiate network functions according to the automatic NSI creation function to create an NSI.

    Abstract: Apparatuses, systems, and methods for load balancing and mobility robustness in cellular systems. A network entity such as a near-RT RIC may receive ranges of handover (HO) parameters and/or performance targets for a mobility robustness optimization (MRO) function and/or a load balancing optimization (LBO) function from a service management and orchestration framework (SMOFW) and receive and analyze HO related performance measurements and/or cell load measurements from an open RAN (O-RAN) distributed unit (O-DU) or centralized unit (O-CU). The near-RTI RIC, based on the analysis, may request the SMOFW to change virtualized resources, request the O-DU update HO parameters, and/or request the O-DU/O-CU update UE selection, cell selection and/or handover parameters.

    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: An apparatus of a management service equipment includes processing circuitry. To configure the management service equipment for measuring a plurality of key performance indicators (KPIs) in a 5G network with a plurality of network functions (NFs), the processing circuitry is to retrieve using a data analytic function of the management service equipment, a plurality of performance measurements associated with a cell of a radio access network (RAN) within the 5G network. A KPI of the plurality of KPIs associated with the cell is generated using the data analytic function of the management service equipment, based on the plurality of performance measurements. The KPI is encoded for transmission to a service application executing on a user equipment (UE) active within the cell of the RAN or executing within a cloud architecture.

    Abstract: 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.

    Abstract: 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.
