Rrc Tab

Available in gNB CU Nodal and gNB CU Node when SA Mode is enabled.

Select the version for RRC.

Options : 15.7.0/Sep2019, 16.2.0/Oct2020, 16.5.0/July2021

Default: 15.7.0/Sep2019

Tcl Parameter:

Available in gNB CU Node when SA Mode is enabled.

The ZERO value of "Inactive Time" means gNB CU Node will NOT go to RRC INACTIVE state actively. Otherwise,  gNB CU Node will try to go RRC INACTIVE state when there is no control messages and data packets (IDLE) for the period of "Inactive Time".

Range : Range is 0 or 5000-10000 in milliseconds. Zero means timer is disabled

default : 0

Tcl Parameter:

Available in gNB CU Node when SA Mode is enabled. Select for RRC Connection Reestablishment reject with RRC Setup. According to O-RAN.WG5.C.1, once a RRC Reestablishment Request is received, the network may return RRC Connection Reestablishment reject with RRC Setup for certain reasons, for example, UE context does not exist, UE context cannot be validated, or if UE is using an invalid C-RNTI.

Note that when RRC Setup is received, the UE will need to reset the upper layer protocol ( i.e. NAS-5G ) and resume with Service Request. A fresh UE context will be created during the Service Request procedure. In current implementation, there is a one second delay between when RRC Setup is received and when RRC Setup Complete ( with Service Request encapsulated ) is sent. If there happens to be uplink data pending during the delay, the Service Request will be sent with Request Type Data. Otherwise the Service Request will be sent with Request Type Signalling.

Handover Type

Available in gNB CU Node. Select to support Intra gNB-DU, Intra Cell Handover procedure can be successfully completed between gNB-CU and gNB-DU from different vendors, conforming to the NR C-Plane profile specification [2] Section 6.5.1 in document O-RAN.WG5.C.1-v07.00.

Note : This checkbox was previously named "DRB ID Change at PDCP SN".

The Purpose of the procedure is to provide Intra Cell HO e.g. in case of Security Key Change, DRBid change or Full Reconfiguration (PDCP Count wrap around) during NR operation or Intra Cell Handover with Security Key Change.

When Trigger Intra Cell Handover at PDCP SN is enabled, select the Handover Type. 

Options : DRB ID Change, Security Key Change or Full Configuration at PDCP SN 

If F1-AP Version is 15.3.0, Handover Type is not allowed to be "Full Configuration".

The message flow follows Figure 6.5.1.1-1 of O-RAN.WG5.C.1. 

1. CU Node sends UE Context Modification Request to initiate the intra-cell handover. The message contains a DRB To Be Modified List to inform DU which DRB is to handover.
2. DU responds with UE Context Modification Response to inform the CU that the DRB is modified successfully.
3. CU sends DL RRC Message Transfer that contains RRC Reconfiguration to inform DU to reestablish PDCP and update master key for the DRB.

The "Intra Cell Handover" panel is disabled when Measurement Configuration/"Enable Measurement Configuration" is checked.
