Abstract

A method for changing channels in a wireless communication terminal includes requesting real-time content of a first channel from a content service system; receiving and playing the requested real-time content of the first channel after establishing a session with the content service system; requesting channel change from the content service system when a user makes the channel change request; and receiving and playing real-time content of a second channel from the content service system through the session established with the content service system.

Claims

1. A method for changing channels in a wireless communication terminal, comprising:

requesting real-time content of a first channel from a content service system;

receiving the real-time content of the first channel through a session established with the content service system;

requesting channel change from the content service system; and

receiving real-time content of a second channel from the content service system through the session established with the content service system.

2. The method of claim 1, wherein the operation of requesting channel change comprises maintaining the session established with the content service system without returning to a browser.

3. The method of claim 1, wherein the operation of receiving real-time content of a second channel comprises stopping the real-time content of the first channel and playing the real-time content of the second channel.

4. The method of claim 1, wherein the real-time content comprises multimedia content.

5. The method of claim 1, wherein the real-time content comprises Digital Multimedia Broadcasting content.

6. The method of claim 1, wherein the real-time content comprises Video On Demand content.

7. A method for changing channels in a content service system, comprising:

receiving a request for real-time content of a first channel from a wireless communication terminal;

establishing a session between the wireless communication terminal and a content server;

providing the real-time content of the first channel through the session established between the wireless communication terminal and the content server;

receiving a request for a channel change from the wireless communication terminal; and

providing real-time content of a second channel to the wireless communication terminal through the session established between the wireless communication terminal and the content server.

8. The method of claim 7, wherein providing real-time content of a second channel further comprises:

terminating a connection between a server connection unit of the content service system and the first channel;

establishing a connection between the server connection unit and the second channel; and

transmitting the real-time content of the second channel to the server connection unit.

9. The method of claim 8, wherein the server connection unit stores information related to real-time content available on channels corresponding to a plurality of content servers.

10. The method of claim 8, wherein receiving a request for a channel change comprises:

receiving a channel connection request;

searching for a content server corresponding to a channel identified in the channel connection request;

connecting the wireless communication terminal to the content server corresponding to the channel identified in the channel connection request through the session established between the wireless communication terminal and the content server.

11. The method of claim 7, further comprising:

transmitting a packet to the content server.

12. The method of claim 7, wherein the real-time content comprises multimedia content.

13. The method of claim 7, wherein the real-time content comprises Digital Multimedia Broadcasting content.

14. The method of claim 7, wherein the real-time content comprises Video On Demand content.

15. A content service system having a channel change function, comprising:

a wireless communication terminal to transmit a channel change request; and

a content server to establish a session with the wireless communication terminal and to provide real-time content of a first channel and real-time content of a second channel to the wireless communication terminal through the session.

16. The content service system of claim 15, further comprising:

a server connection unit to store information related to real-time content available on channels corresponding to a plurality of content servers.

17. The content service system of claim 16, wherein when a channel change request is received from the wireless communication terminal, the server connection unit searches for a content server corresponding to a requested channel and connects the wireless communication terminal to the content server that corresponds to the requested channel through the session.

18. The content service system of claim 16, wherein the server connection unit transmits a packet to the content server at regular intervals to maintain the session with the wireless communication terminal.

19. The content service system of claim 15, wherein the real-time content comprises multimedia content.

20. The content service system of claim 15, wherein the real-time content comprises Digital Multimedia Broadcasting content.

21. The content service system of claim 15, wherein the real-time content comprises Video On Demand content.
