US 2021/0243592 A1 · PCI CONFIGURATION AND MOBILITY ROBUSTNESS OPTIMIZATION SON FUNCTIONALITY FOR 5G NETWORKS

Abstract

Systems and methods of re-configuring PCI values for a NR cell and performing mobility robustness optimization are described. To reconfigure the PCI values. The NRM data and the PCI of candidate cells measurements are analyzed to detect a potential PCI collision or PCI confusion among NR cells. In response to detection of the potential PCI collision or confusion, a new PCI value for at least one NR cell is determined and instructions to re-configure the at least one NR cell with the new PCI value are sent to a producer of provisioning MnS. For MRO, a NF provisioning MnS with modifyMOIAttributes operation to configure MRO targets for an MRO function and to enable the MRO function for a NR cell are consumed, as is a performance assurance MnS with a notifyFileReady or reportStreamData operation to collect MRO-related performance measurements. The measurements are analyzed to evaluate MRO performance.
