IPC: H04W88/02
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of unnecessary correspondence to a telephone call by requiring the response of a man, permitting a message to make a response for a constant designated period and restoring a system to a state where the man automatically makes the response after a prescribed period passes. SOLUTION: A business man depresses a timer key 9 showing 'in train' and inputs '21' by using the ten key of a keyboard 5, for example. The timer key 9 of 'in train' is depressed again immediately before he gets into the train and switch to a message state is decided. The portable telephone set 1 continuously maintains the message state for 21 minutes from that moment. When a telephone call is made during the message state, calling sound informing reception is not rung but the telephone set itself automatically makes the response. The response message is previously recorded by himself or the electronic sound message of 'The response cannot be given because I'm in the train' which is previously prepared is used. The system is automatically restored from the message state to a state where the man can make the response after 21 minutes passes.
