Abstract:
1. An apparatus for enhanced data communications between a vehicle and a remote data communication terminal, the apparatus comprising: a first protocol converter associated with a vehicle, adapted to be positioned in communication with at least one electronic subsystem of the vehicle, and positioned to convert data from a vehicle communication protocol to data of an over-the-air communication protocol; a first requestor associated with the vehicle and positioned to request the opening of an over-the-air communication window in a data communication channel between the vehicle and a remote data communication terminal using the over-the-air communication protocol; a first transceiver associated with the vehicle and in communication with the first requestor to wirelessly transmit data over-the air to the remote data communication terminal and to wirelessly receive data over-the-air from the remote data communication terminal; a first buffer associated with the vehicle, in communication with the first transceiver and the first protocol converter to receive and temporarily store data communication received from the first transceiver, and positioned to transfer the received data to the first protocol converter and to at least one electronic subsystem when the first transceiver is not transmitting data communication therefrom; a second transceiver associated with the remote data communication terminal to wirelessly receive data over-the-air from the vehicle and wirelessly transmit data over-the-air to the vehicle; a second protocol converter associated with the remote data communication terminal and in communication with the second transceiver to convert the received data from the over-the-air communication protocol to a remote terminal communication protocol during the open over-the-air window in the over-the-air communication channel; a second requestor associated with the remote data communication terminal and positioned to request the opening of a window in the data communication channel between the remote data communication terminal and the vehicle using the over-the-air communication protocol; and a second buffer associated with the remote data communication terminal, in communication with the second transceiver and the second protocol converter to receive and temporarily store data communication received from the second transceiver, and positioned to transfer data to the second protocol converter and the remote data communication terminal when the second transceiver is not transmitting data therefrom.
