Access 




• Subscribers using mobility services 

(either GTP or PMIPv6) 

• Subscriber session is anchored on 

the MPC (PGW/GGSN) and also 

maintained on iWAG 

• IP address for the subscribers are 

allocated from the MPC, iWAG acts 

as a proxy DHCP server 

• Subscribers maintain IP address 

persistency while roaming across 

Wi-Fi to Wi-Fi or Wi-Fi to 3G/4G 

• Subscriber authentication is 

typically performed using out-ofband 

or in-band EAP-SIM/AKA 

• Simple IP users do not receive a 

mobility service (either GTP or 

PMIPv6) 

• Subscriber session is anchored 

and maintained on iWAG 

• IP address for the subscribers are 

allocated either via external 

DHCP server or via iWAG itself 

• Subscribers are not expected to 

have IP persistency while roaming 

• Subscriber authentication is 

typically performed using webauthentication 

or/and Transparent 

Auto-Logon 


ISG Features 

• IPoE Sessions: DHCP initiated, 

unclassified IP or MAC-address 

initiator, Radius-Proxy initiator 

• Layer-4 Redirect 

• Traffic Classes 

• Postpaid & Prepaid Accounting 

• Dynamic Rate Limiting 

• Lawful Intercept 

• Radius based authentication and 

accounting 

• Radius CoA Interface 

• Per-subscriber QoS 

• IP Session keep-alives, timeouts 

• VRF Transfer 

• Port Bundle Host Key (PBHK) 

• Walk-by session handling/optimization 

• Local Breakout of subscriber 

traffic for Simple IP subscribers

• Service Providers 

• Reduce network congestion: Reduce OpEx and increase network efficiency by 

offloading 3G/4G traffic 

• Provide Wi-Fi security and subscriber control: Deliver scalable, 

manageable, and secure wireless connectivity with a low TCO 

• Deliver a Wi-Fi platform that offers new, location-based services and enables new 

revenue-sharing business models 

• Users 

• Provide access to 3G/4G core inspite of lack of / weak cell signal 

• Provide a good QoE to subscribers on Wi-Fi networks similar to that provided on 

3G/4G networks 

• QoS based on subscriber profile and traffic classification 

• Provide access to mobile backhaul which could have better bandwidth and thus 

provide better service 

• Deliver a Wi-Fi platform that enables location-based services 



• Proxy Mobile IPv6 Domain: A network where the 

mobility management of a mobile node is handled 

using the Proxy Mobile IPv6 protocol. 

• Local Mobility Anchor (LMA): LMA is the home 

agent for the mobile node in a PMIPv6 domain. It is 

the topological anchor point for the mobile node's 

home network prefix and is the entity that manages 

the mobile node's binding state. 

• Mobile Access Gateway (MAG): MAG is a function 

on an access router that manages the mobilityrelated 

signaling for a mobile node that is attached to 

its access link. It is responsible for tracking the 

mobile node's movements to and from the access 

link 

• Mobile Node (MN): An IP host or router whose 

mobility is managed by the network. The MN may be 

an IPv4-only node, IPv6-only node, or a dual-stack 

node and is not required to participate in any IP 

mobility related signaling for achieving mobility for an 

IP address that is obtained in that PMIPv6 domain. 

• Correspondent Node (CN): The device that the 

mobile node (MN) is communicating with such as a 

web server. A correspondent node may be either 

mobile (e.g. another MN) or stationary (e.g. server). 


• Proxy Mobile IPv6 Domain: A network where the 

mobility management of a mobile node is handled 

using the Proxy Mobile IPv6 protocol. 

• Local Mobility Anchor (LMA): LMA is the home 

agent for the mobile node in a PMIPv6 domain. It is 

the topological anchor point for the mobile node's 

home network prefix and is the entity that manages 

the mobile node's binding state. 

• Mobile Access Gateway (MAG): MAG is a function 

on an access router that manages the mobilityrelated 

signaling for a mobile node that is attached to 

its access link. It is responsible for tracking the 

mobile node's movements to and from the access 

link 

• Mobile Node (MN): An IP host or router whose 

mobility is managed by the network. The MN may be 

an IPv4-only node, IPv6-only node, or a dual-stack 

node and is not required to participate in any IP 

mobility related signaling for achieving mobility for an 

IP address that is obtained in that PMIPv6 domain. 

• Correspondent Node (CN): The device that the 

mobile node (MN) is communicating with such as a 

web server. A correspondent node may be either 

mobile (e.g. another MN) or stationary (e.g. server). 


• By keeping key mobility parameters constant 

throughout the Wi-Fi network/WLAN: 

A. MN’s IP address & anchor point 

B. MN’s Gateway IP address 

C. Gateway’s MAC (or Link-Layer address in IPv6) – 

RFC6543 

• Tracking the movement of Mobile Node – intra & 

inter MAG movements 

• In addition, the DHCP server is reachable and 

consistent throughout the Wi-Fi mobility domain 


• Cisco PMIPv6 implementation is address family 

agnostic: 

• Mobile Nodes in a PMIPv6 domain operating in IPv4- 

only, IPv6-only, or in dual-stack mode 

• Transport network between the MAG and LMA can be 

either IPv4-only, IPv6-only or dual-stack (where IPv4 

would be preferred)
