Abstract

A communication service unit 1 connected with a plurality of communication terminals 3 sends additive information stored in an additive information storing unit 2 before the sending of communication information including visual data, audio data and/or text data sent for an original purpose of communication, while temporarily stopping the sending of the communication information during the communication based on the communication information, or after the completion of the sending of the communication information. Or, a transmission band permitted for the communication information is narrowed in the communication service unit 1 or an instruction is sent from the communication service unit 1 to one communication terminal 3 of a sending end to decrease a transfer rate of the communication information temporarily or from beginning to end of the communication, and the additive information is sent within a transmission band preset for the communication information.

Claims

1. A communication service unit, which is connected with a plurality of communication terminals, receives communication information sent from one communication terminal of a sending end for an original purpose of communication and sends additive information in case of the sending of the communication information to one communication terminal of a receiving end,

characterized in that the additive information relating to or not relating to the communication based on the communication information is sent to the communication terminal of the receiving end within a transmission band permitted for the sending of the communication information before the sending of the communication information, during the sending of the communication information or after the completion of the sending of the communication information.

2. A communication service unit according to claim 1, wherein the additive information to be sent to each communication terminal is stored in advance and is sent.

3. A communication service unit according to claim 1, wherein the communication service unit is connected with an additive information storing server for storing in advance the additive information to be sent to each communication terminal and the additive information stored in the additive information storing server is read out and sent.

4. A communication service unit according to claim 1, wherein the sending of the communication information is temporarily stopped, and the additive information is sent within the transmission band of the communication information.

5. A communication service unit according to claim 1, wherein a transmission band used for the sending of the communication information is narrowed temporarily or from beginning to end of the communication based on the communication information, and the additive information is sent by using a portion of the transmission band not used for the sending of the communication information.

6. A communication service unit according to claim 1, wherein an instruction is sent to the communication terminal of the sending end to decrease a transfer rate of the communication information, and the additive information is sent by using a portion of a transmission band not used for the sending of the communication information within the transmission band permitted for the sending of the communication information.

7. A communication service unit according to claim 1, wherein a transfer rate of the communication information is decreased, and the additive information is sent by using a portion of a transmission band not used for the sending of the communication information within the transmission band permitted for the sending of the communication information.

8. A communication service unit according to claim 1, wherein a data transmission logical path is additionally set within a communication channel used for the sending of the communication information, and the additive information is sent by using the data transmission logical path within the transmission band of the communication channel permitted for the sending of the communication information.

9. A communication service unit according to claim 1, wherein a transmission band different from a transmission band actually used for the sending of the communication information sent for the original purpose of communication is prepared temporarily or from beginning to end of the communication based on the communication information, and the additive information is sent by using the obtained transmission band within the transmission band of the communication channel permitted for the sending of the communication information.

10. A communication service unit according to claim 1, wherein a call of a communication channel independent of a call of a communication channel used for a communication service is newly set, and the additive information is sent within the transmission band of the communication channel permitted for the sending of the communication information.

11. A communication service unit according to claim 1, wherein the additive information is formed of guide information relating to a method of using the communication information currently sent.

12. A communication service unit according to claim 1, wherein the additive information is formed of advertisement information of a third person not directly relating to a method of using the communication information currently sent.

13. A communication service unit according to claim 1, wherein the additive information is written according to a markup language.

14. A communication service unit according to claim 1, wherein the additive information is coded according to a coding method which is the same as that used for the communication information sent for the original purpose of communication.

15. A communication service unit according to claim 1, wherein the additive information is coded according to a coding method which differs from that used for the communication information sent for the original purpose of communication.

16. A communication service unit according to claim 1, wherein the additive information and the communication information sent for the original purpose of communication are combined with each other to produce combined information, and the combined information is coded according to a coding method, which is the same as that used for the communication information sent for the original purpose of communication, and is sent.

17. A communication service unit according to claim 16, wherein the additive information and the communication information are combined with each other according to a display-combination method in a case where the communication information is formed of visual information.

18. A communication service unit according to claim 16, wherein the additive information and the communication information are respectively coded as objects different from each other in a case where the communication information is formed of visual information, and the additive information and the communication information are combined with each other according to an object coding combination method.

19. A communication service unit according to claim 16, wherein the additive information and the communication information are combined with each other according to an audio addition method.

20. A communication method, in which a plurality of communication terminals are connected with each other through a communication service unit, communication information sent from one communication terminal of a sending end for an original purpose of communication is received, and the communication service unit sends additive information when the sending of the communication information to one communication terminal of a receiving end,

characterized in that the communication service unit sends the additive information relating to or not relating to the communication based on the communication information to the communication terminal of the receiving en within a transmission band permitted for the sending of the communication information before the sending of the communication information, during the sending of the communication information or after the completion of the sending of the communication information.
