The invention provides systems and methods for allowing internetwork data transfers to mobile data devices. In particular, the invention includes systems for internetworking a CDPD network system with an Internet protocol network, and more particularly with a Mobile Internet Protocol Network. In one aspect, the invention can be understood as systems that allow mobile computing systems to negotiate the exchange of data across two disparate networks by providing within at least one of the networks a system that redirects the destination of data packets in order that the redirected data packets get forwarded to the changing locations of the Mobile Computing system. In another aspect, the invention can be understood as systems that allow a Mobile computing system to negotiate the exchange of data across disparate networks by providing a redirecting element within one of the networks that will redirect data packets destined for that mobile computing system to the transient location of the computing element.

1. A method for internetworking packet-switched networks that support mobility management functions, comprising:routing packets to a mobile unit located in a first packet-switched network employing a first network protocol that supports mobility management functions; and routing packets between the first packet-switched network and a second packet-switched network when the mobile unit traverses to a location in the second packet-switched network, wherein the second packet-switched network employs a second network protocol that supports mobility management functions and wherein the second network protocol is different from the first network protocol.
