fiveg_core_gnb

Usage

Within 5G, the CU is the Central Unit of a RAN (Radio Access Network) and needs to be configured according to the 5G network parameters.

The fiveg_core_gnb relation interface describes the expected behavior of any charm claiming to be able to provide or consume the CU (or gNodeB) configuration information.

In a typical 5G network, the provider of this interface would be a CU or a gNodeB. The requirer of this interface would be the NMS (Network Management System).

Direction

flowchart TD
    Provider -- MCC, MNC, TAC, SST, SD --> Requirer
    Requirer -- CU/gNodeB Identifier --> Provider

As with all Juju relations, the fiveg_core_gnb interface consists of two parties: a Provider and a Requirer.

Behavior

Both the Requirer and the Provider need to adhere to criteria to be considered compatible with the interface.

Provider

Is expected to provide the following data:
- TAC (Tracking Area Code)
- List of PLMNs

The list of PLMNs should include the following data:

MCC (Mobile Country Code)
MNC (Mobile Network Code)
SST (Slice Service Type)
SD (Slice Differentiator)

Requirer

Is expected to provide a unique identifier of the CU (or gNodeB).
