The method is for monitoring biological data in a human body. A sensor (102)senses biological data (103) from a human body (105) and sends the biologicaldata (103) to a control unit (104) that sends the biological data (103) to acommunicator (106). The communicator compares the biological data (103) totriggering values (111). The communicator only transmits the biological datawhen the triggering values have been exceeded by the biological data. Thecommunicator sends an alert signal (114) including the biological data (103)in a dedicated bandwidth (116) to a server (108). A decision rule engine (112)analyzes the biological data and decides which message to send and to whichrecipient based on the biological data. A medical institution (150) pays a fee(148) to a service unit (138) for accessing the system (100).
