Ia Profile Support


The Ia profile is part of the H.248 functionality that is required for communication on the DBE. The Ia profile is an H.248 profile for the reference point between the Service Policy Decision Function (SPDF) and the DBE (Border Gateway Function (BGF)), also known as the Ia reference point.

The SPDF interacts with the BGF to request services. The Ia reference point is used for communication between the SPDF and a Core Border Gateway Function (C-BGF) and between the SPDF and an Interconnect Border Gateway Function (I-BGF). The H.248 profile defined by ESTI TISPAN for this interface is documented at ETSI ES 283 018.

Information About Ia Profile Support

The Ia profile is an H.248 profile for the reference point between the Service Policy Decision Function (SPDF) and the DBE (Border Gateway Function (BGF)), also known as the Ia reference point. The SPDF interacts with the BGF to request services. The Ia reference point is used for communication between the SPDF and a Core Border Gateway Function (C-BGF) and between the SPDF and an Interconnect Border Gateway Function (I-BGF). The Ia profile name is ETSI_BGF.

The Ia profile supports the control of the following functionality in IP-to-IP Media Gateways:

opening and closing gates (for example, packets filtering depending on IP address/port)

allocation and translation of IP addresses and port numbers (NAPT)

hosted NAT traversal

packet marking for outgoing traffic

resource allocation and bandwidth reservation

policing of incoming traffic

usage metering
