Call Admission Control(CAC) on GGSN ensures that required network resources are available for real-time data traffic, such as voice, video, etc., and to support establishment and modification of the QoS parameters by signalling and negotiating during PDP context activation procedure and modification procedure. CAC performs this by examining various QoS parameters like traffic class, maximum bit rate and guaranteed bit rate for both uplink and downlink received from the SGSN with the local configured parameters or policy received from Policy Decision Function(PDF). This table represents various parameters required to support CAC.
