Abstract

Methods and apparatus for sending an MMS-message, such as an e-mail, a fax and/or an SMS, from a first subscriber device in an MMS-enabled system to a second subscriber device. The MMS-message is converted before being forwarded to the second subscriber device, if the second subscriber device is not connected to an MMS-enabled system or cannot received MMS-messages. Also, an interface device converts and forwards the MMS-message to a subscriber device for specifying the message format.

Claims

1. A method for sending a MMS message from a first subscriber device in a MMS-enabled communication system to a second, non-MMS enabled subscriber device, comprising:

specifying, at the first subscriber device or at an interface of the MMS-enabled communication system, a message transfer format for the second subscriber device;

converting the content and at least some of the information elements of this MMS message which is to be sent to the second subscriber device in accordance with said specified message transfer format by an interface device of the MMS-enabled system of the first subscriber device, if the second subscriber device is linked into a communication system that is not MMS-enabled or is not able to receive MMS messages, and

forwarding said converted MMS message to the second subscriber device, if the second subscriber device is at least one of not linked into a MMS-enabled system or not able to receive MMS messages.

2. The method as claimed in claim 1, wherein the one or more information elements includes at least one of a recipient address and an additional information element of the MiMS message.

3. The method as claimed in claim 2, wherein the additional information element contains an information element name or header field name in binary encoding “

Ox1B”

, in accordance with the WAP MMS encapsulation standard, and the following assignment of message formats takes place;

MMS message (MM) = <

octet 128>

, E-mail = <

octet 129>

, Facsimile = <

octet 130>

, SMS = <

octet 131>

, Voice mail = <

octet 132>

.

4. The method as claimed in claim 1, wherein the interface device executes conversion of the MMS message from the first subscriber device.

5. The method as claimed in claim 1, wherein when the MMS message is converted, the MMS message is associated with a transfer protocol for the message transfer format that has been specified for the MMS message to be sent to the second subscriber device.

6. The method as claimed in claim 5, wherein the transfer protocol is generated from the information elements of the MMS message.

7. The method as claimed in claim 6, wherein at least some of the information elements of the MIMS message to be sent to the second subscriber device are converted into control information items that can be analyzed by a communication system of the second subscriber device.

8. The method as claimed in claim 7, further comprising:

converting at least some information elements of the MIMS message; and

adding the converted information elements to the content of the MMS message for the second subscriber device, the converted information elements comprising information elements that cannot be converted into the control information elements that can be analyzed by the communication system of the second subscriber device.

9. The method as claimed in claim 1, further comprising:

transferring a confirmation report from an interface device of the MMS-enabled communication system to the first subscriber device, the confirmation report relating to at least one of receipt of the MMS message by said interface device or relating to forwarding of the MMS message to the second subscriber device.

10. The method as claimed in claim 9, wherein the confirmation report includes at least one of a designation of the message transfer format, a type of the second subscriber device, or a confirmation of the forwarding using a message transfer format which was specified by the first subscriber device.

11. The method as claimed in claim 1, further comprising:

executing at the interface device at least the following one of depending on a condition result;

checking whether the second subscriber device belongs to the MMS-enabled communication system and forwarding the MMS message to the second subscriber device in the MMS-enabled communication system when the second subscriber belongs to the system;

checking whether the second subscriber device belongs to another at least one other MMS-enabled system, and forwarding the MMS message to the second subscriber device when the second subscriber device belongs to the at least one other system.

12. The method as claimed in claim 11, further comprising:

not forwarding the MMS message, and informing the first subscriber device accordingly when the second subscriber does not belong to the MMS-enabled communication system or the at least one other MMS-enabled communication system.

13. The method as claimed in claim 11 further comprising:

specifying at the first subscriber device a message transfer format of the second subscriber device, the message transfer format including formats for MMS, e-mail, facsimile and SMS; and

forwarding the MMS message or the message which has been converted into the specified message transfer format, to the second subscriber device.

14. The method as claimed in claim 11, further comprising:

specifying at the first subscriber device a message transfer format of the second subscriber device, the message transfer format including in particular message transfer formats for MMS, e-mail, facsimile and SMS; and

forwarding the MMS message, or the MMS message after it has been converted into the specified message transfer format to the second subscriber device that has been specified by the first subscriber device prior to checking executed by the interface device.

15. The method as claimed in claim 11, wherein the method is executed either in parallel or consecutively for each subscriber device that is to receive the MMS message from the first subscriber device.

16. The method as claimed in claim 11 further comprising:

forwarding the MMS message to the second subscriber device, wherein the second subscriber device has been specified by the first subscriber device or the interface device, when forwarding the MMS message has not been previously unsuccessfully attempted.

17. The method according to claim 1, wherein at least some of the information elements of said MMS message to be sent to the second subscriber device are mapped onto information elements that are substantially identical for the recipient-side communication system of the second subscriber device.

18. The method according to claim 1, wherein the MMS message includes at least one of an e-mail, a fax, a SMS, a text file, a graphics file, an audio file and a video file.

19. A subscriber device for an MMS-enabled communication system for sending a MMS message to at least one other subscriber device that is not linked to an MMS-enabled communication system or not able to receive MMS messages, comprising:

an interface device for the MMS-enabled system of the subscriber device;
