EXECUTIVE SUMMARY Connecting femtocells to operator networks requires unique architectures that address the security needs of operators and mobile u

Connecting femtocells to existing operator networks requires a network architecture that addresses the security needs of operators and mobile users,

Femtocell Network Gateway (FNG). This is also shown in Figure 1. For packet calls, depending on the airlink technology, there can be either a PDSN or

The security gateway supports a large number of femtocells connecting to the operator’s network. While similar to traditional VPN gateways used in e
