An access terminal identity based mobility is provided in which a first network tunnel is established between an access gateway and a first access router, and a second network tunnel is established between the access gateway and a second access router. At the access gateway, source addresses of packets sent from an access terminal to a remote correspondent node are translated by replacing the local address of the access terminal with the public address of the access terminal. The access terminal continuously maintain a communication session with the correspondent node as the access terminal moves from a first location to a second location and switches from accessing the first access router to accessing the second access router. A mapping between the local address and the public address is updated as the access terminal switches from the first access router to the second access router.

Network address translation for tunnel mobility

In addition to other aspects disclosed, through a non-secure network, one or more bidirectional secure logical connections are established between a mobile base station and a secure network interface.

Secure mobile base station connections

A method includes establishing a secure connection between a client device and a first security gateway, the first security gateway being associated with a service provider for providing a service to the client device, and handing off the secure connection from the first security gateway to a second security gateway. Handing off the secure connection includes sending from the first security gateway to the second security gateway security information used to encrypt and decrypt messages transmitted through the secure connection, and sending from the first security gateway to the client device an address of the second security gateway to enable the client device to initiate contact with the second security gateway.
