IP Multimedia Subsystem(IMS) has been introduced in
3GPP release 5 for the provision of multimedia services.
The Gateway terminates the GPRS Bearer to carry IMS signaling
and traffic. It communicates with Policy Decision
Function(PDF) over the Go interface and acts as a Policy
Enforcement Point(PEP) to enforce QoS per media flows
using COPS protocol.
This table represents various parameters required to
support IMS. This table is deprecated as IMS is not
supported from GGSN 5.0 release onwards.
