  • Patent number: 8010136
    Abstract: A mobile platform is equipped with a transceiver to receive a broadcast message and to execute two-way wireless communications. The mobile platform is also equipped with an electronic memory storage device, a processor, and a human-machine interface. A first message is formed at the communications source, broadcasted, and received at the mobile platform by way of the transceiver. A portion of the first message is selectively cached in the electronic memory storage device and selectively communicated to the human-machine interface. A second message is formed and wirelessly communicated between the communications source and the mobile platform by way of the two-way wireless communications device.
