Abstract

A method and a device for transmitting electronic mail messages using a mobile wireless telephone network short message service are provided. An electronic mail message is transmitted by using the at least one short message which includes a short message header portion and a short message data portion. The short message data portion includes a user data header portion having: a) an identifying data field to identify that the short message data portion includes addressing information in accordance with RFC 822, and b) a length data field identifying a length of the addressing information in accordance with RFC 822. The addressing information in accordance with RFC 822 includes data fields differentiated from one another by keywords.

Claims

1. A method of transmitting electronic mail messages using a mobile wireless telephone network short message service, comprising:

transmitting at least one short message by using the mobile wireless telephone network short message service;

preparing an electronic mail message to be transmitted by means of the at least one short message;

incorporating a short message header portion and a short message data portion in the at least one short message;

incorporating a user data header portion in the short message data portion, the user data header portion preceded by a user data header length field, the user data header portion having an identifying data field, only a single length data field, and a plurality of addressing information data fields;

indicating, using the identifying data field, that the short message data portion includes addressing information in accordance with RFC 822;

indicating, using the single length data field, a length of the entire addressing information in accordance with RFC 822;

incorporating the entire addressing information in accordance with RFC 822 in the plurality of addressing information data fields of the user data header portion, said addressing information data fields being differentiated from one another by predetermined code values representative of keywords; and

transmitting the electronic mail message by means of the at least one short message.

2. The method of claim 1, wherein said electronic mail message is transmitted using a plurality of short messages, and wherein said short message data portion further includes an identifier for identifying said electronic mail message.

3. The method of claim 1, wherein said electronic mail message is transmitted using a plurality of short messages, and wherein said short message data portion further includes a sequence number identifier of a sequence of short messages for concatenation of said short messages in a correct order.

4. The method of claim 1, wherein said electronic mail message is transmitted using a plurality of short messages, and wherein said short message data portion further includes an identifier for identifying said electronic mail message, and wherein said short message data portion further includes a sequence number identifier of a sequence of short messages for concatenation of said short messages in a correct order.

5. The method of claim 1, wherein said mobile wireless telephone network operates according to the GSM standard.

6. The method of claim 1, wherein said mobile wireless telephone network operates according to the UMTS standard.

7. The method of claim 1, wherein said short message header portion includes signaling entries, a destination address and a source address.

8. The method of claim 7, wherein the destination address and the source address are identified by a MSISDN number.

9. A transmitting apparatus for transmitting electronic mail messages using a mobile wireless telephone network short message service, comprising:

an arrangement configured to;

preparing an electronic mail message to be transmitted by means of at least one short message;

incorporate a short message header portion and a short message data portion in the at least one short message;

incorporate a user data header portion in the short message data portion, the user data header portion preceded by a user data header length field, the user data header portion having an identifying data field, only a single length data field, and a plurality of addressing information data fields;

indicate, using the identifying data field, that the short message data portion includes addressing information in accordance with RFC 822;

indicate, using the single length data field, a length of the entire addressing information in accordance with RFC 822;

incorporate the entire addressing information in accordance with RFC 822 in the plurality of addressing information data fields of the user data header portion, said addressing information data fields being differentiated from one another by predetermined code values representative of keywords; and

transmit the electronic mail message using the at least one short message.

10. The transmitting apparatus of claim 9, wherein said short message data portion further includes an identifier for identifying said electronic mail message in the event that said electronic mail message is transmitted using a plurality of short messages.

11. The transmitting apparatus of claim 9, wherein said short message data portion further includes a sequence number identifier of a sequence of short messages for concatenation of said short messages in a correct order in the event that said electronic mail message is transmitted using a plurality of short messages.

12. The transmitting apparatus of claim 9, wherein said short message data portion further includes an identifier for identifying said electronic mail message, and wherein said short message data portion further includes a sequence number identifier of a sequence of short messages for concatenation of said short messages in a correct order in the event that said electronic mail message is transmitted using a plurality of short messages.

13. The transmitting apparatus of claim 9, wherein said transmitting unit is configured to operate according to the GSM standard.

14. The transmitting apparatus of claim 9, wherein said transmitting unit is configured to operate according to the UMTS standard.

15. The transmitting apparatus of claim 9, wherein said short message header portion includes signaling entries, a destination address and a source address.

16. The transmitting apparatus of claim 15, wherein the destination address and the source address are identified by a MSISDN number.
