Abstract
Methods (400, 500) and corresponding systems (100) for handing off between a broadcast network and a cellular network include receiving, in a cooperation platform, incoming data from a content provider. Broadcast data corresponding to the incoming data is then sent to a broadcast network output for broadcasting to one or more subscribers including, a subscriber station. Handoff information from the cellular network is received in the cooperation platform, and, in response to the handoff information, cellular data corresponding to the incoming data is sent to a cellular network output for transmission to the subscriber station. The handoff information can correspond to a user request for handoff sent from the subscriber station via the cellular network, or can be a request for handoff sent from the cellular network based upon a loading level within one or more of the broadcast network and the cellular network.
