▀ How it Works
GGSN-initiated Update PDP Context
WLC-initiated Accounting Interim
This section presents call flow for the session update – WLC-initiated Accounting Interim scenario.
Figure 6.
GGSN-initiated Update PDP Context
This section presents call flow for the session update – GGSN-initiated Update PDP Context scenario.
GGSN-initiated Update PDP Context Request for QoS update is processed at R-eWAG and the QoS associated with the
session is updated. Update PDP Context Request for update of any other parameter will be rejected by R-eWAG. GGSN
might initiate a DPC because of this.
Important:
When R-eWAG receives UPC from GGSN, it compares it with the QoS requested by AAA and QoS with smaller
version is selected for UPC response. In case of same version, QoS with small Max-bit-rate (MBR) is selected.

Note that R-eWAG internally uses R7-QoS regardless of which QoS is requested and negotiated.
