Claim Text:
1. A method for short message service (SMS) between an unmanned vehicle and a cellular network, the method comprising: compiling a short message from information obtained from at least one of a current location, a speed, an altitude, a destination, and a power reserve of the unmanned vehicle; and sending the short message on a repetitive interval over a communication path between the unmanned vehicle and the cellular network, the communication path supporting at least one communication protocol; wherein the short messages are sent from the unmanned vehicle using a first communication protocol, if no reply or conformation received within a time threshold, the short messages are sent via a second communication protocol different from the communication protocol, if still no reply or conformation received within the time threshold, the short messages are sent via the first communication protocol again; wherein the time threshold is smaller than the repetitive interval; wherein the short messages are refreshed on the repetitive interval; and when the power reserve of the unmanned vehicle is below a reserve threshold, the short messages are sent via both the communication protocols and with a reduced repetitive interval.
