Abstract

A mobile terminal prompts a user to make a voice message upon detection of an abnormally interrupted call, and records the message. Then, the mobile terminal converts the recorded voice data and a telephone number of a communication partner'"'"'s terminal into a format suitable for data communication. Next, the mobile terminal transmits the converted data to a mobile data communication relay base station. The mobile data communication relay base station forwards the converted data to a data communication network storage device via a data communication network. A stored message transmitter retrieves the telephone number of the communication partner'"'"'s terminal from the data communication network storage device and calls the communication partner'"'"'s terminal via a fixed telephone network. When communication is established between the stored message transmitter and the communication partner'"'"'s terminal, the stored message transmitter reproduces the voice data retrieved from the data communication network storage device in response to a request from the communication partner'"'"'s terminal.

Claims

1. A call interruption compensating method for use with a call interruption communication system which includes a mobile terminal, a data communication relay station installed in a vehicle or a building for wireless communication with said mobile terminal, a data communication network storage device for receiving data from said data communication relay station via a data communication network, and a stored message transmitter connected to said data communication network storage device for communication with a communication partner'"'"'s terminal connected to a mobile telephone terminal or to a fixed telephone terminal, for communicating a message of the user of said mobile terminal to the user of said communication partner'"'"'s terminal when a call with said communication partner'"'"'s terminal is abnormally interrupted due to a faulty communication associated with said mobile terminal, said method comprising the steps of:

prompting the user of said mobile terminal to make a message, and recording the message when an abnormal interruption of a call is detected in the vehicle or the building by means of said mobile terminal;

converting recorded voice data and telephone number data of said communication partner'"'"'s terminal into a format suitable for data communication by means of said mobile terminal;

transmitting the converted data to said data communication relay station by said mobile terminal;

connecting to said data communication network by wired or wireless access to transmit the received converted data to said data communication network storage device via said data communication network by means of said data communication relay station;

retrieving the telephone number data of said communication partner'"'"'s terminal from said data communication network storage device, and calling said communication partner'"'"'s terminal via said mobile telephone network or via said fixed telephone network by means of said stored message transmitter; and

reproducing the voice data retrieved from said data communication network storage device in response to a request from said communication partner'"'"'s terminal by means of said stored message transmitter.

2. A call interruption compensation system comprising:

a mobile terminal for prompting a user to make a voice message and recording the message upon detecting an abnormally interrupted call within a vehicle or a building, converting the recorded voice data and telephone number data of a communication partner'"'"'s terminal into a format suitable for data communication, and wirelessly transmitting the converted data;

a data communication relay station installed in the vehicle or the building for receiving the converted data from said mobile terminal, and transmitting the converted data to a data communication network through a wireless or a wired connection to said data communication network;

a data communication network storage device for receiving the converted data from said data communication relay station via said data communication network; and

stored message transmitter connected to said data communication network storage device for retrieving the telephone number data of said communication partner'"'"'s terminal from said data communication network storage device, calling said communication partner'"'"'s terminal by a mobile telephone network or by a fixed telephone network, and reproducing the voice data retrieved from said data communication network storage device in response to a request from said communication partner'"'"'s terminal.

3. A mobile terminal comprising:

means for detecting an abnormally interrupted call within a vehicle or a building;

means for prompting a user to make a voice message and recording the message upon detecting an abnormally interrupted call;

means for converting the recorded voice data and telephone number data of a communication partner'"'"'s terminal into a format suitable for data communication; and

means for transmitting the converted data to a data communication relay station installed in the vehicle or the building.

4. A computer program product for causing a computer which serves as a mobile terminal to execute the steps of:

detecting an abnormally interrupted call within a vehicle or a building;

prompting a user to make a voice message in response to the detection of an abnormally interrupted call, and recording the message;

converting the recorded voice data and telephone number data of a communication partner'"'"'s terminal into a format suitable for data communication; and

transmitting the converted data to a data communication relay station installed in the vehicle or the building.

5. A computer readable recoding medium on which a computer program is recorded for causing a computer which serves as a mobile terminal to execute the steps of:

detecting an abnormally interrupted call within a vehicle or a building;

prompting a user to make a voice message in response to the detection of an abnormally interrupted call, and recording the message;

converting the recorded voice data and telephone number data of a communication partner'"'"'s terminal into a format suitable for data communication; and

transmitting the converted data to a data communication relay station installed in the vehicle or the building.
