Figure 7. SCG as MAG
Following are the considerations for PMIPv6 support on the SCG.
• The SCG acts as an integrated WLAN controller and MAG
• The signaling transport network between MAG and LMA is PMIPv6 over IPv4-
only. The user plane is IPv4 over GRE over IPv4. Future versions of the SCG will
support IPv6 or dual stack
• The service offered to mobile node is IPv4 whereby only IPv4 addresses are
assigned to the MN
• It is assumed that the LMA supports binding revocation indication procedures.
This is required for handling the inter MAG handover procedures
• The SCG maintains heartbeats in terms of Internet control message protocol
towards the LMA
• The SCG supports all MN authentication procedures supported over Ruckus
APs (for example, Portal, WISPr, 802.1x, EAP-SIM/EAP-AKA/EAP). The SCG
setups the PMIP tunnel appropriately on the DHCP trigger and assigns it to the
UE IPv4 address as seen in
to the LMA.
