The iWAG sends a query to the DNS server to resolve a given Access Point Name (APN) to a GGSN IP
address.

14

The DNS server sends the DNS-resolved GGSN address back to the iWAG.

15

After receiving the DNS-resolved GGSN address, the iWAG sends the Create PDP Context Request, in
which the PDP context address is set to 0, in order to request the GGSN for an IP address assignment.

16

The GGSN sends a RADIUS Access Request to the AAA server.

17

Based on the cached information obtained from the EAP-SIM authentication, the AAA server replies with
a RADIUS Access Accept message to the GGSN.

18

The GGSN sends the Create PDP Context Response that carries the assigned IP address c.c.c.c for the
subscriber, to the iWAG.

19

The iWAG sends a DHCP Offer message to the mobile device.

20

The mobile device sends a DHCP Request message to the iWAG, and the iWAG acknowledges this request
by sending a DHCP ACK message to the mobile device.

21

The WiFi subscriber traffic now has a data path through which it can flow.
