Configuring the LBO
To configure Local Break Out, use the following configuration:
config
amf-global
dnn-policy policy_name
lbo-roaming-allowed { true | false }
end
NOTES:
-
dnn-policy policy_name —Specify the DNN policy name.
-
lbo-roaming-allowed { true | false } —Specify LBO roaming allowed or not. Configuring lbo-roaming-allowed has minimum priority. The priorities are as follows:
-
When UE includes a DNN name in the PDU Establishment Request, the DNN name is validated with the UDM subscription data. The LBO flag in the UDM subscription data has maximum priority.
-
When UE doesn't include DNN name in PDU Establishment Request, AMF checks for the default DNN in UDM subscription. If the default DNN is available in the UDM subscription, the LBO flag is considered from the UDM subscription data.
-
When UE doesn't include DNN name and UDM doesn't provide any default DNN, AMF checks for the configured default DNN. The corresponding DNN policy is checked for the configured default DNN and the LBO is configured using Configuring the LBO.
When lbo-roaming-allowed configured as true, or UDM sends this flag, LBO roaming is considered. Otherwise Home-routed roaming is considered.
