Node-Functionality AVP Support

The Oracle Communications Session Border Controller sends the Node-Functionality (862) AVP in all Rf ACR messages.

The Node-Functionality AVP indicates the function that the message’s source plays in the network. The CDF/CGF function that collects the ACR messages can use the information in the Node Functionality AVP for billing or analysis purposes.

In an IMS network, theOracle Communications Session Border Controller may perform the following functions: P-CSCF, E-CSCF, IBCF, BGCF (when configured as an Oracle Communications Session Router). In fact, the system might perform different roles simultaneously, so that on a call-by-call basis, the value in the Node-Functionality might change.

To accurately reflect multiple, simultaneous functions that the Oracle Communications Session Border Controller performs, the value inserted into the Node-Functionality AVP may be defined per realm. The node functionality value for a call’s ACR is taken from the configuration in the ingress realm. Each realm may only be marked with a single Node Functionality value.

The system can still be configured with a single, global Node Functionality value. This is done in the SIP config’s node functionality parameter. When configured, all system-generated ACRs include this value. However, if the node functionality parameter is also configured in a realm config, the ingress realm’s node functionality value supersedes the global value.

The node-functionality in the realm-config may be configured with an empty string (). This indicates that this realm should revert to the global node-functionality value.
