Abstract
The present invention supports mobility for a mobile node between different packet data services. In one embodiment, the invention includes listening for a registration message from a mobile node at an external interface of a gateway node of a wireless packet service, the registration message containing a care-of address for the mobile node that is outside of the wireless packet service, accepting a registration message from the mobile node at the external interface, and registering the mobile node to the care-of address contained in the registration message. This embodiment further includes sending a registration reply message to the mobile node via the care-of address, the registration reply message indicating successful registration, creating a binding for the mobile node, tunneling packets addressed to the mobile node to the care-of address, and receiving tunneled packets from the mobile node, decapsulating the tunneled packets and sending them to the appropriate address.
