4.2.11
As part of the E2E solution supported by the ISAM 7750 service router, the
G-240W-G ONT offers Mobile Offload support using a combination of EAP-SIM and
ITU-T 802.11.
EAP-SIM is an authentication method that uses the user credentials on the SIM card
and EAP to authenticate the user with the Wi-Fi network, removing the need for user
input (username and password).
A dedicated public mobile offload SSID in the ONT enables mobile subscribers to
connect to the Internet. Encryption is supported by 802.11, providing seamless Wi-Fi
authentication for SIM-based user equipment.
The ONT acts as the RADIUS client and sends the encapsulated EAP messages to
the AAA server via the WLAN Gateway, which acts as the RADIUS proxy server. The
interaction between the ONT and the AAA server provides subscriber management
for authenticated mobile users without adding authentication load to the 3G network.
4.2.12
This section describes the support for soft GRE tunnels for integration with the 7750
Service Router WLAN gateway. The Nokia 7750 Service Router WLAN GW can
accept soft GRE tunnels from any IP Source Address, in a preconfigured Subnet or
Access Control List, or MPLS label.
4.2.12.1
Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a
wide variety of network layer protocols inside virtual point-to-point links over an
Internet Protocol network. GRE provides a secure path for transporting packets
through a public network. In essence, GRE creates a private P2P connection, similar
to a VPN, between clients and servers. GRE is the preferred transport mechanism
between the Carrier Wi-Fi access network and the WLAN GW.
