Patent ID: 7020708

Claim:
A method of providing wireless data communication services, comprising: establishing a radio communication path, via a voice network, between a moving object and a first ground station using a data communication server co-located with the moving object, the data communication server including a plurality of interface units for accessing different data networks including an Ethernet interface unit, an Integrated Services Digital Network (ISDN) interface unit, and a pre-determined wireless data network interface unit; said step of establishing including the steps of: sending a channel request signal to the first ground station; and receiving an acknowledgement signal, including a channel assignment, back from the first ground station indicating a channel is being made available and being assigned for the radio communication path; initiating call setup procedures including sending in-band signaling to the first ground station in response to a tone from the first ground station, the first ground station, in response to the in-band signaling, establishing a connection with a second ground station and bridging the radio communication path with the connection to the second ground station; training at least one modem of the moving object to be in communication with a first ground station modem, the first ground station modem substantially simultaneously training itself to be in communication with a second ground station modem; transmitting data to said second station, via the first ground station, using a pre-determined protocol for the radio communication path and second pre-determined protocol for the connection between the first ground station and the second ground station; and establishing a link layer connection between the moving object and the first ground station using a point-to-point protocol over the voice network.
