Abstract

A method of transmitting electronic mail messages using the least possible data capacity. It uses a short message service, an electronic mail message and address and/or identification data for transmission of the electronic mail message in a second communications network is transmitted with a short message in a first communications network. A first header including signaling of at least one data field, including the address and/or identification data, is transmitted with the short message. A second header, indicating the presence of the first header, is transmitted with the short message. The at least one data field is transmitted outside of any header within a data portion of the short message.

Claims

1. A method of transmitting internet electronic mail messages using a short message service, the method comprising:

transmitting with a short message an electronic mail message and address data and identification data, for transmission of the electronic mail message via the internet, in a mobile telephone network;

transmitting a first header with the short message, the first header including signaling of at least one data field including the address data and identification data;

transmitting a second header with the short message, the second header indicating the presence of the first header; and

transmitting, outside of any header, the at least one data field within a data portion of the short message;

identifying the at least one data field by a keyword for transmission in the data portion; and

transmitting with the short message at least one third header that identifies the electronic mail message as part of a complete electronic mail message concatenated by transmission of multiple short messages;

wherein the first header information is placed in front of the at least one data field having the address data and identification data and transmitted with the short message.

2. The method of claim 1, wherein keywords are transmitted in coded form.

3. The method of claim 1, wherein an identifying data field includes the signaling of the at least one data field, and is transmitted with the first header.

4. The method of claim 3, wherein the identifying data field indicates a form of the at least one of address data and identification data.

5. The method of claim 1, wherein the at least one data field in the data portion of the electronic mail message is transmitted immediately before the electronic mail message.

6. The method of claim 1, wherein at least one destination address data field, which includes a destination address of the electronic mail message, is transmitted in the data portion.

7. The method of claim 1, wherein a source address data field, which includes the source address of the electronic mail message, is transmitted in the data portion.

8. The method of claim 1, wherein a title data field, which includes a title of the electronic mail message, is transmitted in the data portion.

9. The method of claim 1, wherein a name data field, which includes a name of a sender of the electronic mail message, is transmitted in the data portion.

10. The method of claim 1, wherein an end of the at least one data field is identified by a separation character.

11. The method of claim 1, wherein a length data field is transmitted with the first header to indicate a length of the at least one data field.

12. The method of claim 1, wherein the at least one data field is transmitted so that it is separated from the electronic mail message by a separation character.

13. The method of claim 1,

wherein keywords are transmitted in coded form,

wherein an identifying data field includes the signaling of the at least one data field, and is transmitted with the first header,

wherein an end of the at least one data field is identified by a separation character,

wherein a length data field is transmitted with the first header to indicate a length of the at least one data field,

wherein the at least one data field is transmitted so that it is separated from the electronic mail message by a separation character,

wherein the identifying data field indicates a form of the at least one of address data and identification data.

14. The method of claim 13, wherein the at least one data field in the data portion of the electronic mail message is transmitted immediately before the electronic mail message.

15. The method of claim 13, wherein at least one destination address data field, which includes a destination address of the electronic mail message, is transmitted in the data portion.

16. The method of claim 13, wherein a source address data field, which includes the source address of the electronic mail message, is transmitted in the data portion.

17. The method of claim 13, wherein a title data field, which includes a title of the electronic mail message, is transmitted in the data portion.

18. The method of claim 13, wherein a name data field, which includes a name of a sender of the electronic mail message, is transmitted in the data portion.

19. The method of claim 13, wherein the at least one data field in the data portion of the electronic mail message is transmitted immediately before the electronic mail message, and wherein at least one destination address data field, which includes a destination address of the electronic mail message, is transmitted in the data portion.

20. The method of claim 19, wherein a title data field, which includes a title of the electronic mail message, is transmitted in the data portion.

21. The method of claim 19, wherein a name data field, which includes a name of a sender of the electronic mail message, is transmitted in the data portion.

22. The method of claim 13, wherein a source address data field, which includes the source address of the electronic mail message, is transmitted in the data portion, and wherein the at least one data field in the data portion of the electronic mail message is transmitted immediately before the electronic mail message.

23. The method of claim 22, wherein a title data field, which includes a title of the electronic mail message, is transmitted in the data portion.

24. The method of claim 22, wherein a name data field, which includes a name of a sender of the electronic mail message, is transmitted in the data portion.

25. A method of transmitting internet electronic mail messages using a short message service of a mobile telephone network, the method comprising:

transmitting with a first short message an internet electronic mail message,

wherein said short message includes a message header portion and a message data portion, the message data portion includes a user data header portion, a data area and a message portion and wherein said message header portion includes a signaling entry indicating that an electronic mail message is being transmitted with the short message, said data area includes data fields representing addressing information in accordance with RFC 822 and said user data header portion includes a first data field indicating that said data area contains fields representing addressing information in accordance with RFC 822, a second data field indicating a length of said fields representing addressing information and a third data field indicating a length of said second data field, and

wherein said data area is immediately before said message portion,

wherein said electronic mail message is transmitted with a plurality of short messages, said plurality of short messages comprising said first short message, a final short message and optionally one or more intermediate short messages, and

wherein each of said first, final and intermediate short messages includes information for enabling a receiver to concatenate said short messages in a correct order.

26. The method according to claim 25, wherein said mobile telephone network is a GSM mobile phone network.

27. The method according to claim 25, wherein said mobile phone network is a UMTS mobile phone network.

28. The method according to claim 25, wherein each of said first, final and intermediate short messages include information for enabling a receiver to concatenate said short messages in a correct order, and wherein said mobile telephone network is a GSM mobile phone network.

29. The method according to claim 25, wherein each of said first, final and intermediate short messages include information for enabling a receiver to concatenate said short messages in a correct order, and wherein said mobile phone network is a UMTS mobile phone network.
