Abstract

A method, apparatus, and computer product for avoiding redundant data transmissions during communication via multimedia mobile phones. In operation, a sending party inquires whether intended for transmission data already resides in a mobile phone of a receiving party Depending on a content of the response from the receiving party, the sending party transmits the data or a request for displaying the already available data.

Claims

1. A method, performed by a multimedia mobile device involving an outgoing transmission including graphical/video data, comprising:

sending, to a receiving mobile device, an identifier of the data;

determining, prior to initially sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data identified by the identifier; and

sending, to the receiving mobile phone, only the portion of the data identified by the identifier not contained by the receiving mobile device, wherein

the portion is less than all of the data identified by the identifier.

2. The method of claim 1, wherein

the identifier includes at least one of:

a checksum of a file of the data identified by the identifier,

a name of the file of the data identified by the identifier,

a template used to organize/format the data identified by the identifier, and

a textual or symbolic description of the data identified by the identifier.

3. The method of claim 1, wherein

the data identified by the identifier includes at least one of:

digitized voice,

text,

graphics, and

video information.

4. The method of claim 1, wherein

at least a portion of the communications use Short Message Service (SMS) communication protocol.

5. The method of claim 1, wherein

the determining that the receiving mobile phone does not contain the portion of the data identified by the identifier is based upon a response from a server containing a registry of files saved at the receiving mobile device.

6. A multimedia mobile device, comprising:

at least one hardware processor, wherein the at least one hardware processor is configured to perform and/or initiate involving an outgoing transmission including graphical/video data;

sending, to a receiving mobile device, an identifier of the data;

determining, prior to initially sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data identified by the identifier; and

sending, to the receiving mobile phone, only the portion of the data not contained by the receiving mobile device, wherein

the portion is less than all of the data identified by the identifier.

7. The device of claim 6, wherein

the identifier includes at least one of:

a checksum of a file of the data identified by the identifier,

a name of the file of the data identified by the identifier,

a template used to organize/format the data identified by the identifier, and

a textual or symbolic description of the data identified by the identifier.

8. The device of claim 6, wherein

the data identified by the identifier includes at least one of:

digitized voice,

text,

graphics, and

video information.

9. The device of claim 6, wherein

at least a portion of the communications use Short Message Service (SMS) communication protocol.

10. The device of claim 6, wherein

the determining that the receiving mobile phone does not contain the portion of the data identified by the identifier is based upon a response from a server containing a registry of files saved at the receiving mobile device.

11. A computer program product, comprising:

a computer usable hardware storage device having stored therein computer usable program code,

the computer usable program code, which when executed by a multimedia mobile device, causes the multimedia mobile device to perform the following involved in an outgoing transmission including graphical/video data;

sending, to a receiving mobile device, an identifier of the data;

determining, prior to initially sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data identified by the identifier; and

sending, to the receiving mobile phone, only the portion of the data not contained by the receiving mobile device, wherein

the portion is less than all of the data identified by the identifier.

12. The computer program product of claim 11, wherein

the identifier includes at least one of:

a checksum of a file of the data identified by the identifier,

a name of the file of the data identified by the identifier,

a template used to organize/format the data identified by the identifier, and

a textual or symbolic description of the data identified by the identifier.

13. The computer program product of claim 11, wherein

the data identified by the identifier includes at least one of:

digitized voice,

text,

graphics, and

video information.

14. The computer program product of claim 11, wherein

at least a portion of the communications use Short Message Service (SMS) communication protocol.

15. The computer program product of claim 11, wherein

the determining that the receiving mobile phone does not contain the portion of the data identified by the identifier is based upon a response from a server containing a registry of files saved at the receiving mobile device.
