Abstract

A system for identifying an originator based on an image and a method thereof are disclosed. The method includes: transmitting a session initiate protocol INVITE message by inserting predetermined image information in the session initiate protocol INVITE message at a transmitting terminal; and displaying an image by analyzing image information included in a received session initiate protocol INVITE message transmitted from the transmitting terminal at a receiving terminal.

Claims

1. A method for identifying an originator based on an image comprising:

transmitting a session initiate protocol INVITE message by inserting predetermined image information in the session initiate protocol INVITE message at a transmitting terminal; and

displaying an image by analyzing image information included in a received session initiate protocol INVITE message transmitted from the transmitting terminal at a receiving terminal.

2. The method according to claim 1, wherein the session initiate protocol INVITE message is transmitted through a call session control function of an Internet protocol multimedia subsystem.

3. The method according to claim 2, wherein the image information is recorded in an opaque field in a session initiate INVITE message.

4. The method according to claim 1, wherein in the transmitting of the session initiate protocol INVITE message, the transmitting terminal transforms the image information to a text data suitable to be inserted in the opaque field in the session initiate protocol INVITE message, inserts the transformed text data into the opaque field in the session initiate protocol INVITE message and transmits the session initiate protocol INVITE message with the text data, and

wherein in the displaying of the image, the receiving terminal extracts text formatted image data from the opaque field of the session initiate protocol INVITE message, transforms the extracted text formatted image data to binary image data, decodes the binary image data to an original image data using a decoder and displays the original image data.

5. The method according to claim 1, wherein the image information is obtained when transmitting or one of stored images is selected, the obtained or selected image information is compressed and the compressed image information is transmitted.

6. The method according to claim 1, wherein the image information is JPEG image data and the JPEG image data is recorded in the session initiate protocol INVITE message.

7. A transmitting terminal in a system for identifying an originator based on an image transmitted from the originator before connecting a call, the transmitting terminal comprising:

a message creating unit for crating a session initiate protocol INVITE message by inserting image information in the session initiate protocol INVITE message; and

a transmitting unit for transmitting the created session initiate protocol INVITE message.

8. The transmitting terminal according to claim 7, further comprising:

an image obtaining unit for obtaining an image using a camera when transmitting; and

a compressing unit for compressing the obtained image.

9. The transmitting terminal according to claim 7, further comprising a JPEG compressing unit for compressing the image information in a JPEG format and recording the compressed image information in the session initiate protocol INVITE message.

10. The transmitting terminal according to claim 7, further comprising a format transforming unit for transforming the image information to text data and recording the text data into an opaque field in the session initiate protocol INVITE message.

11. A receiving terminal in a system for identifying an originator based on an image transmitted from the originator before connecting a call, the receiving terminal comprising:

a message receiving unit for receiving a session initiate protocol INVITE message;

a data analyzing unit for analyzing image information included in the received session initiate protocol INVITE message; and

a display for displaying the analyzed image information.

12. The receiving terminal according to claim 11, wherein the data analyzing unit extracts the image information from an opaque field in the session initiate protocol INVITE message.

13. The receiving terminal according to claim 11, further comprising a format transforming unit for transforming text formatted image information included in the session initiate protocol INVITE message to binary image information.

14. The receiving terminal according to claim 13, wherein the binary image information is compressed image data, and

further comprising a decoder for decoding the compressed image data to an original image data.

15. The receiving terminal according to claim 13, wherein the binary image information is a JPEG image data, and

further comprising a JPEG decoder for decoding the JPEG image data to an original image data.

16. A transmitting/receiving terminal in a system for identifying an originator based on an image transmitted fro the originator in an Internet protocol multimedia subsystem environment, the transmitting/receiving terminal comprising:

an image format transforming unit for transforming an image data for identifying an originator before connecting a call to a text data or transforming a received text data to a binary image data;

a message creating and analyzing unit for creating a session initiate protocol INVITE message by recording the transformed text data into a predetermined field of the session initiate protocol INVITE message or analyzing a text formatted image data in a predetermined field of a received session initiate protocol INVITE message;

a transmitting/receiving unit for transmitting or receiving a session initiate protocol INVITE message having the text formatted image data; and

a display for displaying an image recovered through analyzing and transforming.

17. The system according to claim 16, further comprising:

a camera for obtaining the image; and

a compressing and recovering unit for compressing image data to be recorded in the session initiate protocol INVITE message as a text format, or extracting the image data from the session initiate protocol INVITE message and recovering the image data to an original image.
