Abstract

A terminal includes a communication unit to transmit a first custom message to a called terminal according to a video call request, and to receive a connect message from the called terminal; and a connection unit to setup a session for the video call with the called terminal, and if a second custom message is received from the called terminal, to replace the session with a fast session for a high-speed video call. A method for establishing the fast session of a video call includes transmitting the first custom message to the called terminal, receiving a connect message, setting up a session for the video call with the called terminal, and replacing the session with a fast session for a high-speed video call if a second custom message is received from the called terminal.

Claims (41)

1. A terminal, comprising:

a communication unit to transmit a first custom message to a called terminal according to a video call request, and to receive a connect message from the called terminal, the called terminal being identified by the video call request; and

a connection unit to setup a session for the video call with the called terminal in interoperation with the received connect message, and if a second custom message is received from the called terminal during the video call, to replace the session with a fast session for a high-speed video call.

2. The terminal of claim 1 , further comprising:

a detection unit to set an initial skip byte as a predetermined value and to perform a mobile level detection if an H.324 recreation is performed as a set preliminary processor for the fast session during the video call through the session.

3. The terminal of claim 1 , further comprising:

a verification unit to verify whether the second custom message is received from the called terminal during a read period, the read period determined based on a time that the session is set.

4. The terminal of claim 3 , wherein the verification unit adjusts the read period based on a mobile level detection performed in association with an H.324 recreation performed in the fast session.

5. The terminal of claim 1 , wherein the connection unit transmits or receives a preference message through the fast session, and performs a high-speed video call with the called terminal.

6. The terminal of claim 1 , wherein the connection unit initializes an H.324 recreation to setup the fast session according to the video call request.

7. The terminal of claim 1 , wherein the communication unit transmits information about a calling terminal to a Multimedia Ring Back Tone (MRBT) server, and receives an MRBT from the MRBT server using the information about the calling terminal.

8. A method for establishing a fast session of a video call, the method comprising:

transmitting a first custom message to a called terminal according to a video call request, the called terminal being identified by the video call request;

receiving a connect message from the called terminal;

setting up a session for the video call with the called terminal in interoperation with the received connect message; and

replacing the session with a fast session for a high-speed video call if a second custom message is received from the called terminal during the video call.

9. The method of claim 8 , further comprising:

setting an initial skip byte as a predetermined value and performing a mobile level detection if an H.324 recreation is performed as a set preliminary processor for the fast session during the video call through the session.

10. The method of claim 8 , further comprising:

verifying whether the second custom message is received from the called terminal during a read period, the read period determined based on a time that the session is setup.

11. The method of claim 10 , further comprising:

adjusting the read period based on a mobile level detection performed in association with an H.324 recreation performed in the fast session.

12. The method of claim 8 , further comprising:

transmitting or receiving a preference message through the fast session, and performing the high-speed video call with the called terminal.

13. The method of claim 8 , further comprising:

initializing an H.324 recreation to setup the fast session.

14. The method of claim 8 , further comprising:

transmitting information about a calling terminal to a Multimedia Ring Back Tone (MRBT) server according to the video call request; and

receiving an MRBT from the MRBT server using the information about the calling terminal.

15. A computer, comprising:

a processor; and

a computer-readable recording medium storing a program to implement a method for establishing a fast session of a video call if the program is executed, the method comprising:

transmitting a first custom message to a called terminal according to a video call request, the called terminal being identified by the video call request;

receiving a connect message from the called terminal;

setting a session for the video call with the called terminal in interoperation with the received connect message; and

replacing the session with a fast session for a high-speed video call if a second custom message is received from the called terminal during the video call.

16. A method for establishing a fast session of a video call, the method comprising:

receiving a first custom message from a called terminal, the called terminal being identified by the video call request;

transmitting a connect message to the called terminal;

setting up a session for the video call with the calling terminal; and

replacing the session with a fast session for a high-speed video call after transmitting a second custom message to the called terminal.
