Abstract

An IP network and a communication method therein. The IP network includes a first terminal adapted to make an outgoing call and a second terminal adapted to transmit information on a plurality of serviceable communication modes other than a communication mode of the call incoming from the first terminal depending upon whether the incoming call is connected.

Claims

1. An IP (Internet protocol) network, comprising:

a first terminal adapted to make an outgoing call; and

a second terminal adapted to transmit information on a plurality of serviceable communication modes other than a communication mode of the call incoming from the first terminal depending upon whether the incoming call is connected.

2. The IP network of claim 1, wherein the information on the plurality of communication modes is included and transmitted in a session initiation protocol (SIP) message.

3. The IP network of claim 2, the first terminal transmits an SIP INVITE message including the information on the plurality of serviceable communications modes to the second terminal upon making the outgoing call.

4. The IP network of claim 3, wherein the second terminal is further adapted to receive the information on the possible plurality of communication modes of the first terminal from the first terminal, the second terminal being further adapted to display each of the plurality of communication modes of the first terminal on a screen.

5. The IP network of claim 2, the second terminal being adapted to convert the information on the plurality of serviceable communication modes other than the communication mode of the incoming call into a message form upon being in a busy state, the second terminal being further adapted to include the information on the plurality of serviceable communication modes other than the communication mode of the incoming call in a message form in a session description protocol (SDP) body portion of a 486 Busy Here message, the second terminal being further adapted to transmit the 486 Busy Here message comprising the information on the plurality of serviceable communication modes other than the communication mode of the incoming call to the first terminal.

6. The IP network of claim 2, wherein, upon a user of the second terminal selecting to communicate with the first terminal in a communication mode other than the communication mode of the incoming call, the second terminal is adapted to convert the information on the plurality of serviceable communication modes other than the communication mode of the incoming call into message form, the second terminal being further adapted to include the information in message form in a session description protocol (SDP) body portion of a 200 OK message, and the second terminal being further adapted to transmit the included information to the first terminal.

7. The IP network of claim 5, wherein the first terminal is adapted to receive the information on the plurality of communication modes of the second terminal from the second terminal, the first terminal being further adapted to display each of the plurality of communication modes on a screen.

8. The IP network of claim 7, wherein, upon a user of the first terminal selecting one of the plurality of displayed communication modes of the second terminal, the first terminal being further adapted to transmit a call attempt message to the second terminal in the selected communication mode.

9. The IP network of claim 1, wherein each of the plurality of communication modes use a communication service selected from the group consisting of VoIP (Voice over IP), VT (Video Telephony), PTT (Push To Talk), PTV (Push To Video), PTD (Push To Data), IM (Instant Message), and MMC (Multi Media Conference).

10. The IP network of claim 1, wherein the IP network uses a communications interface selected from the group consisting of CDMA (code division multiple access), WLAN (wireless local area network), Wibro (wireless broadband Internet), WiMax (World Interoperability for Microwave Access), and HSDPA (high-speed downlink packet access) communication interfaces.

19. The method of claim 11, wherein each of the plurality of communication modes uses a communication service selected from the group consisting of VoIP (Voice over IP), VT (Video Telephony), PTT (Push To Talk), PTV (Push To Video), PTD (Push To Data), IM (Instant Message) and MMC (Multi Media Conference).

11. A communication method in an Internet protocol (IP) network, comprising:

making an outgoing call from a first terminal to a second terminal; and

transmitting, from the second terminal to the first terminal, information on a plurality of serviceable communication modes of the second terminal besides a communication mode of the call from the first terminal, depending on whether the call is connected.

12. The method of claim 11, wherein the information on the plurality of communication modes is included and transmitted in a session initiation protocol (SIP) message.

13. The method of claim 12, wherein, during the transmitting of the outgoing call from the first terminal, information on a plurality of serviceable communication modes of the first terminal is inserted and transmitted in a SIP INVITE message of the outgoing call.

14. The method of claim 13, further comprising:

receiving, at the second terminal, the information on the plurality of possible communication modes of the first terminal; and

displaying each of the communication modes of the first terminal on a screen at the second terminal.

15. The method of claim 12, wherein the transmitting, from the second terminal to the first terminal, of the information on the plurality of other serviceable communication modes of the second terminal besides the communication mode of the call from the first terminal comprises:

converting the information on the plurality of serviceable communication modes of the second terminal other than the communication mode of the incoming call into message form upon the second terminal being in a busy state;

preparing a 486 Busy Here message;

inserting the converted information on the plurality of communication modes into an session description protocol (SDP) body portion of the 486 Busy Here message; and

transmitting the prepared 486 Busy Here message comprising the converted information on the plurality of communication modes to the first terminal.

16. The method of claim 12, wherein the transmitting, from the second terminal to the first terminal, of the information on a plurality of other serviceable communication modes of the second terminal besides the communication mode of the call from the first terminal comprises:

converting the information on the plurality of serviceable communication modes of the second terminal other than the communication mode of the incoming call to the second terminal into message form upon the second terminal being in an idle state or upon a user of the second terminal selecting to communicate with the first terminal in a communication mode other than the communication mode of the incoming call;

preparing a 200 OK message;

inserting the converted information on the plurality of communication modes into a session description protocol (SDP) body portion of the 200 OK message; and

transmitting the prepared 200 OK message to the first terminal.

17. The method of claim 15, further comprising:

receiving, at the first terminal, the information on the plurality of communication modes of the second terminal from the second terminal; and

displaying each of the communication modes on a screen at the first terminal.

18. The method of claim 17, further comprising transmitting, by the first terminal to the second terminal, a call attempt message in a selected communication mode from the first terminal to the second terminal upon a user of the first terminal selecting the selected communication mode from the displayed plurality of communication modes of the second terminal.

20. The method of claim 11, wherein the IP network uses at least one communication interface selected from the group consisting of CDMA (code division multiple access), WLAN (wireless local area network), Wibro (wireless broadband Internet), WiMax (World Interoperability for Microwave Access), and HSDPA (high-speed downlink packet access) communication interfaces.
