    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: Embodiments disclosed herein relate to Random Access Channel (RACH) optimization and Automatic Neighbor Relation (ANR) use cases and requirements for 5G networks. For example, embodiments disclosed herein automatically configure RACH parameters and neighbor relations for 5G networks that can generate biggest saving in resource utilization for mobile operators. The RACH optimization disclosed herein can automatically configure the RACH parameters in a cell to achieve the optimal RACH performance by reducing the network access and handoff time, and minimize the failures. The Automatic Neighbor Relation (ANR) management disclosed herein can automatically create and update the neighbor relations that can generate biggest saving in resource utilization for mobile operators.

    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.
