Abstract
A fast and secure ad hoc communication system is established between terminals with the aid of a network. Terminals equipped with a non-cellular interface may establish a high data rate peer-to-peer or multi-hop ad hoc connection with the support of a cellular network. The cellular network may provide signaling for user authentication, peer identification, key distribution for a secure non-cellular connection set-up, radio resources management messages, routing assistance information, as well as charging and billing for the service. A non-cellular link may be used for fast and secure ad hoc communication between the terminals. Signaling may be transported either over a non-cellular access network or, using dual-mode terminals, over the cellular RAN. A combination of the signaling transports is also possible.
