4G DHCP Discover Call Flow
The following is the overview of the 4G DHCP Discover call flow:
1
In the 4G DHCP Session Initiator use-case scenario, iWAG is configured only with DHCP as the session
initiator.
2
On receiving the DHCP discover message from the AP or WLC, the iWAG creates the session.
3
The iWAG sends an Access Request message to the AAA server and downloads the mobility parameters
through an Access Accept message.
4
After receiving the mobility parameters, the iWAG initiates PMIP signaling by sending a PBU message
to the LMA.
5
The LMA responds with a PBA message that includes IP address, gateway, and mask.
6
Now the PMIP tunnel is established between the iWAG and the LMA.
7
The iWAG offers an IP address to the client and creates a binding.
