Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio communication system for trains in which communications within a train are secured without fail by performing position diversity receptions in mobile stations installed on preceding and following cars.  <P>SOLUTION: In the system, an A mobile station 3 in a preceding car 2 always judges whether its own receiving status is good. When the A mobile station 3 is located in a reception defect area A1, the A mobile station 3 captures the receiving status signal of a B mobile station 8 via a longitudinal voice/signal line 14. Further, the A mobile station 3 compares its own receiving status signal with the receiving status signal of the B mobile station 8, and when the receiving status of the B mobile station 8 is better than the receiving status of the A mobile station 3, a reception demodulating signal of the B mobile station 8 is acquired via a longitudinal voice/signal line 12. Then, the position diversity reception is performed by switching to the reception demodulating signal by the B mobile station 8. Thereby, even if the A mobile station 3 in the preceding car 2 is located within the receiving defect area A1, the communication of a high quality level is reliably continued without being interrupted.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To improve the convenience of a telephone system capable of transmitting and receiving mail data at the time of calling or speaking by making the most of the transmitting and receiving function of the mail data. SOLUTION: This portable telephone system inputs melody data and character string data from the outside by an outside operation (110-140), and at the time of inputting a calling command to call the other telephone system (150), encodes the melody data and the character string data into melody transmission data (180), and transmits the melody transmission data to a telephone line network with the telephone number of the calling destination (190). As a result, a calling signal added with the melody data and the character string data is transmitted from the telephone line network to a telephone system at a call incoming side. Then, the call incoming side decodes the melody data added to the calling signal, and reproduces the data as an incoming sound in order to intuitively know the caller.  Also, the call incoming side is able to display a message from the caller at a display device in order to confirm requirements. In this case, mail data constituted of a message and a melody can be transmitted at the time of speaking.
