Systems and methods are discussed for providing multiple network interfaces to devices to communicate with each other using various policies, for using a proxy to maintain a connection with a legacy system such that a data connection to the legacy system may be continued when an end device connects with the proxy, and for maintaining application states when devices become disconnected such that their activities may be resumed when reconnected. Multiple wireless networks allow communication sessions to transfer across each of the multiple wireless networks in a seamless fashion. One wireless network may control the handoff to another wireless network or a mobile device with an OCMP may control the handoff.
