New Feature Summary

This section provides information about new features in the Packet Data Interworking 
Function.

Beginning with Release 8.3, the PDIF supports multiple IPsec traffic selectors.

The PDIF can be configured with multiple IPsec traffic classes, each containing up to 128 
traffic selectors, which are used during traffic selector negotiation with UEs. Multiple 
traffic selectors allow the PDIF to direct outbound traffic to selected IP addresses based on 
the following protocols: IP, TCP, UDP, and ICMP. The PDIF can also direct TCP and UDP 
traffic to selected IP addresses and port ranges.

For more information, see the chapters “Packet Data Interworking Function Overview” and 
“Configuration” in the PDIF Administration Guide.

Beginning with Release 8.3, the PDIF includes a selective Diameter Profile Update Request 
Control feature. For mobile IP calls, this feature allows WiFi data-only sessions to co-exist 
with VoIP sessions on the PDIF platform.

This feature is used to identify which subscriber sessions need to have the PDIF and the 
HSS exchange Diameter Profile Update Request (PUR) and Profile Update Answer (PUA) 
messages, and allows the PDIF to handle the call setup for a data-only client without having 
to interact with the HSS.

This feature is enabled by default and requires no configuration.

For more information, see the chapter “Packet Data Interworking Function Overview” in 
the PDIF Administration Guide.
