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 sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data;

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

determining a checksum of a file of the data;

transmitting, to a server containing a registry of files saved at the receiving mobile device, an inquiry regarding whether the receiving mobile device has a file having the same checksum; and

receiving, from the server, a response to the inquiry, wherein

the determining that the receiving mobile phone does not contain the portion of the data is based upon the response to the inquiry.

2. The method of claim 1, further comprising:

receiving a request, from the receiving mobile phone, for the data;

transmitting, to the receiving mobile device and in response to the request, an inquiry regarding availability of the data at the receiving mobile phone; and

receiving, from the receiving mobile phone and in response to the inquiry, information used to identify the portion of the data not contained by the receiving mobile device.

3. The method of claim 1, wherein

the identifier includes at least one of:

the checksum of the file of the data,

a name of the file of the data,

a template used to organize/format the data, and

a textual or symbolic description of the data.

4. The method of claim 1, wherein

the data includes at least one of:

digitized voice,

text,

graphics, and

video information.

5. The method of claim 1, wherein

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

6. A multimedia mobile device, comprising:

at least one processor, wherein the at least one 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 sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data;

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

determining a checksum of a file of the data;

transmitting, to a server containing a registry of files saved at the receiving mobile device, an inquiry regarding whether the receiving mobile device has a file having the same checksum; and

receiving, from the server, a response to the inquiry, wherein

the determining that the receiving mobile phone does not contain the portion of the data is based upon the response to the inquiry.

7. The device of claim 6, wherein the at least one processor is further configured to perform and/or initiate involving the outgoing transmission:

receiving a request, from the receiving mobile phone, for the data;

transmitting, to the receiving mobile device and in response to the request, an inquiry regarding availability of the data at the receiving mobile phone; and

receiving, from the receiving mobile phone and in response to the inquiry, information used to identify the portion of the data not contained by the receiving mobile device.

8. The device of claim 6, wherein

the identifier includes at least one of:

the checksum of the file of the data,

a name of the file of the data,

a template used to organize/format the data, and

a textual or symbolic description of the data.

9. The device of claim 6, wherein

the data includes at least one of:

digitized voice,

text,

graphics, and

video information.

10. The device of claim 6, wherein

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

11. A computer program product, comprising:

a computer usable storage medium 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 sending the data to the receiving mobile device, that the receiving mobile phone does not contain a portion of the data;

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

determining a checksum of a file of the data;

transmitting, to a server containing a registry of files saved at the receiving mobile device, an inquiry regarding whether the receiving mobile device has a file having the same checksum; and

receiving, from the server, a response to the inquiry, wherein

the determining that the receiving mobile phone does not contain the portion of the data is based upon the response to the inquiry.

12. The computer program product of claim 11, wherein the computer usable program code further causes the multimedia mobile device to perform:

receiving a request, from the receiving mobile phone, for the data;

transmitting, to the receiving mobile device and in response to the request, an inquiry regarding availability of the data at the receiving mobile phone; and

receiving, from the receiving mobile phone and in response to the inquiry, information used to identify the portion of the data not contained by the receiving mobile device.

13. The computer program product of claim 11, wherein

the identifier includes at least one of:

the checksum of the file of the data,

a name of the file of the data,

a template used to organize/format the data, and

a textual or symbolic description of the data.

14. The computer program product of claim 11, wherein

the data includes at least one of:

digitized voice,

text,

graphics, and

video information.

15. The computer program product of claim 11, wherein

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