  • Publication number: 20230396991
    Abstract: A method for stale user context detection and removal is implemented at one of Open Radio Access Network (O-RAN) Centralized Unit (gNB-CU) or Distributed Unit (gNB-DU). In a first variant which utilizes the gNB-CU, the gNB runs a configurable periodic timer for initiating the stale UE detection procedure, i.e., the gNB configures, for every UE context stored in its database, a special Event A1 with the low a1-Threshold=?120 dBm, reportInterval=512 ms, and reportAmount=2. In a second variant which utilizes the gNB-CU, stale UE detection mechanism can be based on a periodic Event A1 configured during initial User admission procedure, i.e., the gNB configures a special Event A1 with the low a1-Threshold=?120 dBm, reportInterval=1 minute, and reportAmount=infinity. In a further variant, stale UE contexts can be identified at the gNB-DU based on periodic Channel State Information (CSI) reports.

  • Publication number: 20230379779
    Abstract: In a method of operating a Radio Access Network (RAN) to optimize a handover between two gNBs, in addition to exchanging the respective AMF region IDs between the two gNBs, all supported GUAMIs of each gNB shall be exchanged as part of the Xn setup procedure, thereby enabling each gNB to know the supported GUAMIs of the peer gNB. Before initiating the Xn handover, source gNB shall check whether the target gNB supports the AMF which currently serves the UE. If supported, the source gNB shall proceed with the Xn-based handover. If the AMF is not supported by the target gNB, the source gNB shall initiate the NGAP handover. In addition, whenever there is any change in supported GUAMIs (addition/deletion/modification), each gNB shall initiate a New Generation Radio Access Network (NG-RAN) Configuration Update procedure towards the peer gNB with the changed list of GUAMIs.
