System and method for multiple packet data network connectivity

摘要

A mobile communication terminal includes an attachment module that provides a request to attach to a home network through a visited network when the mobile communication terminal is roaming. The mobile communication terminal also includes a response module that receives a response to the request to attach from the home network that includes first and second Internet protocol (IP) addresses. The mobile communication terminal also includes a communication module that communicates with a first packet data network (PDN) through the home network by selectively using the first IP address and that communicates with a second PDN through the visited network by selectively using the second IP address.
