VERFAHREN ZUR STEUERUNG VON MINDESTENS EINEM SENDER UND / ODER EINEM EMPFÄNGER, EIN INFORMATIONSVERMITTLUNGSSYSTEM, UND DIE VERWENDUNG DES VERFAHRENS UND DES SYSTEMS

摘要

The method involves transmitting a signal with a message part indicative of later signal transmission time from a transmitter to a receiver. The transmitter and the receiver are brought into a special mode e.g. a sleep mode after receiving and transmitting a conformation signal, respectively. The transmitter and the receiver are brought back to the normal operating mode at-or before- the indicated time of transmission. An independent claim is also included for a communication system having a transmitter and a receiver.
