DHCP-based Enhanced Wireless Access Gateway Overview
Session Update - AAA Initiated
This section presents call flow for the AAA-initiated session update scenario.
Figure 23.
Session Update - GGSN Initiated
This section presents call flow for the GGSN-initiated session update scenario.
GGSN-initiated UPC Request for QoS update would be processed at D-eWAG and the QoS associated with the session
would be updated. UPC request for update of any other parameter would be rejected by D-eWAG. The GGSN may
initiate a DPC because of this.
Important:
When D-eWAG receives UPC from GGSN, it compares it with QoS requested by AAA, and QoS with smaller version
is selected for UPC response. In case of same version, QoS with small Maximum Bit Rate (MBR) is selected.
Important:
Session Update - AAA Initiated Call Flow
Note that D-eWAG internally uses R7-QoS regardless of which QoS is requested and negotiated.
In this release, D-eWAG does not generate CoA RADIUS Request to WLC.
