摘要

A communication system for exchange of messages between one or more mobile operators and at least one traffic operator is characterised in that it contains at least one traffic operator station (TOS1, TOS2...), and at least one mobile operator station (MOS1, MOS2...), both provided with means for sending and/or receiving data with use of USSD protocol. All traffic/mobile operator stations are provided with means for processing of information carried in USSD-compliant messages. They exchange the USSD messages through the cellular network with any standard supporting USSD protocol. The mobile operator station which can be any mobile electronic device provided with a SIM card or circuit and a modem, is provided with the receiver of the geographic positioning signal. At least one sensor of a physical variable and optionally a bar/matrix code reader are connected to the mobile operator station, either remotely or by wire.
