Abstract

To provide a method for transmitting short messages (SMS) between computers (3, 8, 9) in the Internet (4), wherein the short message (SMS) is converted into a data format comprised of a header part (10) and a useful part (32), with at least one data field (11) for determining the data format, at least one data field (16) for identifying the sender, and at least one data field (19) for identifying the recipient being inserted into the header part (10), it is provided that before, during and, optionally, after the transmission of the short message (SMS), character strings (.LOGIN, .SELECT-CHANNEL) are exchanged between computers (3, 8, 9). By using the data format described in combination with the character strings which are exchanged between the computers (3, 8, 9), a protocol (ISMTP, Internet Short Message Transfer Protocol) that is suitable for such a data transfer and variable can be created which is based on a computer network, e.g. a TCP-IP-based network. By using this data format, a protocol suitable for such a data transmission (ISMTP Internet Short Message Transfer Protocol) can be created which is based on a computer network, e.g. a TCP-IP based network.

Claims

1. A method for transmitting a short message between computers in the Internet, wherein the short message is converted into a data format comprised of a header part and a useful part, with at least one data field for determining a data format, at least one data field for identifying a sender, and at least one data field for identifying a recipient being inserted into the header part, comprising before the transmission of the short message, exchanging character strings (.LOGIN, .SELECT-CHANNEL) between computers, wherein prior to the transmission of the short message at least one first character string (.SELECT-CHANNEL) for selecting a channel and at least one second character string (.LOGIN) which contains a user identification for authenticating the sender of the short message are exchanged between computers, and further transmitting a third character string (.QUIT) from the sender of the short message which contains a quitting order to terminate the transmission of the short message.

2. The method according to claim 1, wherein a Multipurpose Internet Mail Extension (MIME) version is entered in the data field for determining the data format.

3. The method according to claim 2, wherein a MIME data field for defining the type of short message is inserted in the header part.

4. The method according to claim 1, wherein a Message Id data field is inserted in the header part to indicate a unique identification for the short message.

5. The method according to claim 1, wherein a Sender Ton data field is inserted in the header part to indicate, the type of network of the sender of the short message.

6. The method according to claim 1, wherein a Sender Npi data field is inserted in the header part to determine the numbering plan of the network of the sender.

7. The method according to claim 1, wherein a Recipient Ton data field is inserted in the header part to determine the type of network of the recipient.

8. The method according to claim 1, wherein a Recipient Npi data field is inserted in the header part to define the numbering plan of the network of the recipient.

9. The method according to claim 1, wherein a Protocol Id data field is inserted in the header part to identify the contents transported with the short message.

10. The method according to claim 1, wherein an Is-Compressed data field is inserted in the header part to indicate a compression of the useful data.

11. The method of claim 1, wherein a Message Class data field is inserted in the header part to distinguish the class of the short message.

12. The method of claim 1, wherein an Alphabet data field is inserted in the header part to determine the code of the useful data.

13. The method of claim 1, wherein a Priority data field is inserted in the header part to determine the priority of the short message.

14. The method of claim 1, wherein a Validity-Period data field is inserted in the header part to input the expiration date of the short message.

15. The method according to claim 1, wherein a Cod data field is inserted in the header part to determine whether or not a confirmation of the receipt of the short message is required.

16. The method according to claim 1, wherein a Replace-If-Present data field is inserted in the header part to determine whether or not a previously created short message is to be replaced by the new short message.

17. The method according to claim 1, wherein a Reply Path data field is inserted in the header part to determine the number of repetitions of the sending attempts for the short message.

18. The method according to claim 1, wherein a Send-On data field is inserted in the header part to determine a desired point of time of sending the short message.

19. The method according to claim 1, wherein a Created-On data field is inserted in the header part to enter the point of time of creating the short message.

20. The method according to claim 1, wherein a Sender-Ip-Address data field is inserted in the header part to transmit Internet addresses of the computers involved in the transmission.

21. The method according to claim 1, wherein the recipient of the short message upon transmission of the second character string (.LOGIN) for authenticating the sender of the short message transmits a character string to the sender which contains at least a status code regarding the success of the authentication.

22. The method according to claim 1, wherein after a successful log-in, the first character string (.SELECT-CHANNEL) is transmitted from the sender to the recipient of the short message which contains data regarding selection of an output channel of the receiving computer.

23. The method according to claim 22, wherein the recipient answers the sender of the short message with a character string which contains data on the success of the selection of the output channel.

24. The method according to claim 23, wherein a character string is transmitted to the sender of the short message as a response of the recipient of the short message which contains data regarding the success of the quitting order.
