Abstract
Methods, systems, and storage media are described for physical-layer cell identifier (PCI) configuration and Mobility Robustness Optimization (MRO). In particular, some embodiments may be directed to fifth-generation self-organizing network (5G SON) solutions such as the management of distributed physical-layer cell identifier (PCI) configuration, centralized PCI configuration, and MRO. Other embodiments may be described and/or claimed.
Claims14
An apparatus comprising:
- memory circuitry to store a physical-layer cell identifier (PCI) list;
- and
- processor circuitry, coupled with the memory circuitry, to instantiate a distributed-PCI (D-PCI) configuration function adapted to:
- detect a PCI conflict among a plurality of new radio (NR) cells;
- reassign PCI values from the PCI list to the plurality of NR cells to mitigate the conflict;
- indicate the PCI values to a management service producer for network function (NF) provisioning, wherein the indication of the PCI values is to cause the management service producer for NF provisioning to send a notifyMOIAttributeValueChange notification, and the notifyMOIAttributeValueChange notification is to indicate the PCI values being reassigned to mitigate the detected PCI conflict;
- detect that the PCI conflict has been resolved;
- generate a resolution notification to indicate the PCI conflict has been resolved;
- and
- indicate the resolution of the PCI conflict to the management service producer for NF fault supervision, wherein the indication of the resolution is to cause the management service producer for NF fault supervision to send a notifyClearedAlarm notification to a D-PCI management function, and the notifyClearedAlarm notification is to indicate the resolution of the PCI conflict.
One or more non-transitory computer-readable media (NTCRM) comprising instructions of a distributed-PCI (D-PCI) configuration function, wherein execution of the instructions by one or more processors is to cause a compute node to:
- detect a physical-layer cell identifier (PCI) conflict among a plurality of new radio (NR) cells;
- reassign PCI values from the PCI list to the plurality of NR cells to mitigate the conflict;
- indicate the PCI values to the management service producer for network function (NF) provisioning, wherein the indication of the PCI values is to cause the management service producer for NF provisioning to send a notifyMOIAttributeValueChange notification, and the notifyMOIAttributeValueChange notification is to indicate the PCI values being reassigned to mitigate the detected PCI conflict;
- detect that the PCI conflict has been resolved;
- generate a resolution notification to indicate the PCI conflict has been resolved;
- and
- indicate resolution of the PCI conflict to the management service producer for NF fault supervision, wherein the indication of the resolution is to cause the management service producer for NF fault supervision to send a notifyClearedAlarm notification to a D-PCI management function, and the notifyClearedAlarm notification is to indicate the resolution of the PCI conflict.
