    Abstract: A method and system to provide Mobility Robustness Optimization (MRO) in a NR network are described. The MRO parameters, use case, management services and information definition and procedures are described. A distributed self-organized network (D-SON) management function requests a producer of provisioning management service (MnS) to set targets, handover parameter ranges, and control information for an MRO function and then enables the MRO function for a non-enabled NR cell. The MRO function receives and analyses information from UEs to determine actions to optimize MRO performance. The D-SON management function collects and analyses MRO related performance measurements to evaluate the MRO performance, and updates the targets, handover parameter ranges, and/or control information when the MRO performance does not meet the targets.

    Abstract: Systems and methods for measurement and reporting of average UL and DL delays and delay distributions for an NG-RAN and UPF, as well as gNB-DU DL latency, for the N3 and N9 interfaces, internal UPF delay, and between the PSA UPF and NG-RAN and between the PSA UPF and UE are described. For the UL and DL average delay and delay distributions, the measurements are split into subcounters per 5QI/QCI, S-NSSAI and/or DSCPs, with the delay distributions subcounters in bins with discrete delay ranges. The measurements aon the N3 interface delay are also differentiated between a PSA UPF and an I-UPF.

    Abstract: Technology is disclosed for a Third Generation Partnership Project (3GPP) management system operable for peer-to-peer (P2P) edge computing in a fifth generation (5G) computing network. The 3GPP management system can be configured to: identify a user plane function (UPF) based on quality of service (QoS) requirements. The 3GPP management system can be configured to request, from an edge computing management system, deployment of an application server (AS). The 3GPP management system can be configured to request a network functions virtualization (NFV) orchestrator (NFVO) to connect the UPF and the AS based on the QoS requirements.

    Abstract: Techniques discussed herein can facilitate edge computing in connection with a variety of deployment scenarios. Various embodiments can facilitate one or more of: deploying UPF(s) (User Plane Function(s)) to support edge computing; removing UPF(s) not needed for edge computing; deploying local DN(s) (Data Network(s)); E2E (Edge-to-Edge) OSS (Operations Support System) deployment scenarios; and providing RAN (Radio Access Network) condition data to support various applications (e.g., autonomous driving).

    Abstract: An apparatus, a system, a computer-readable media, and a method. The method is to be performed at an apparatus of a gNB configured to host a management service (MnS) producer of provisioning function and a mobility robustness optimization (MRO) function in a distributed self-organizing network (D-SON). The method includes: decoding one or more requests from a MRO management function sent on a service-based layer of the D-SON, the one or more requests indicating attributes to be set by the gNB, the attributes including MRO targets, ranges of handover parameters, and a control parameter to enable or disable the MRO function; based on the one or more requests, setting the targets and the ranges of handover parameters for the MRO function, and enabling the MRO function; and in response to a determination that a MRO performance does not meet the targets, performing updates on the attributes to optimize the MRO performance.
