Product Description
The Cisco® ASR 5000 Chassis provides 3GPP mobile operators with a flexible solution that functions as a Femto
Network Gateway (FNG) in CDMA2000 wireless voice and data networks. The FNG consists of new software for the
ASR 5000.
The FNG enables mobile operators to provide 3G network services to subscribers with wireless handsets via Femtocell
Access Points (FAPs). The FNG makes it possible for operators to provide secure access to the operator's 3G network
from a non-secure network, extend wireless service coverage indoors, especially where access would otherwise be
limited or unavailable, reduce the load on the macro wireless network, and make use of existing backhaul infrastructure
to reduce the cost of carrying wireless calls.
The FNG functions as a security gateway that allows the FAPs in the access network to connect to circuit, packet, and
IMS core networks. The FNG implements an IPSec interface to provide a secure, encrypted IPSec tunnel to each FAP in
the access network as it connects to the operator's core network. In addition, the FNG provides a highly scalable
femtocell solution by allowing a large number of FAPs to interoperate with legacy core network elements that are
typically not designed to interface with such a large number of elements.
The FNG splits voice and data traffic flows into and out of the core network. It forwards all voice traffic to the
operator's IMS core network and all data traffic to the PDSN/HA toward the packet data network. This network
configuration fully isolates the traditional MSC from IP attacks, because all backhauled traffic is secure and offloaded to
a convergence server in the IMS core network.
