Abstract

A method of establishing connection between a first mobile station (MS) and a second MS in a mobile communication system is disclosed. More specifically, the method includes transmitting to at least one base station (BS) a service message which includes information of at least one service type supported by the first MS and the second MS. Here the at least one service type relates to a multimedia service supported by each of the first MS and the second MS. Furthermore, the method includes transmitting a request message which includes information of at least one service type selected by the first MS, receiving a response message which includes information of the selected service type which is supported by both the first MS and a second MS, and transmitting a connection complete message between the first MS and the second MS for communication using the selected service type.

5. The method of claim 4, wherein the at least one of still image, animation, avatar, and emoticon follow a control signal which is used to convey at least one of emotion, expression, and movement of a user.

6. The method of claim 5, wherein the control signal is inputted by any one of a short-cut key or a jog-dial provided on the first MS.

7. The method of claim 1, wherein the request message includes an identifier of the second MS and information of a desired service type.

8. The method of claim 7, wherein the identifier is represented by a single bit.

9. The method of claim 7, wherein the desired service type is represented by 16 bits.

10. The method of claim 7, wherein if the identifier is represented by a specified bit, the desired service type is included in the request message.

11. The method of claim 1, further comprising receiving an assignment message through which a traffic channel is assigned for communication with a network.

12. The method of claim 1, wherein the response message is received via a traffic channel.

13. The method of claim 12, wherein the traffic channel is assigned via the response message which includes a field indicating information on at least one service type supported by both the first MS and the second MS.

14. The method of claim 1, further comprising establishing connection with the second MS using the selected service type upon receipt of a command from the network to establish connection.

15. The method of claim 1, further comprising transmitting a change service message to the second MS to request for communication using a different service type during the connected state.

16. The method of claim 15, wherein the change service message includes information of at least one service type.

17. The method of claim 1, wherein a bandwidth allocated for transmitting the service message which includes the information of the at least one service type occupies less bandwidth than a bandwidth used for transmitting video signals including a full video stream.

18. The method of claim 17, wherein at least one service type is transmitted via the allocated bandwidth based on the selected service type.

19. The method of claim 18, wherein at least one of still image, animation, avatar, and emoticon provided by the multimedia service is used to convey at least one of emotion, expression, and movement by using the at least one of still image, animation, avatar, and emoticon pre-stored in the first MS and the second MS.

20. A method of establishing connection between a first mobile station (MS) and a second MS in a mobile communication system, the method comprising:

transmitting a request message which includes information of at least one service type selected by the first MS out of all service types supported by the first MS, wherein the service types relate to multimedia services;

receiving a response message which includes information of the selected service type which is supported by both the first MS and a second MS; and

transmitting a connection request message between the first MS and the second MS for communication using the selected service type.

21. The method of claim 20, further comprising transmitting to at least one base station (BS) a message including information of at least one service type supported by the first MS.

22. The method of claim 20, further comprising receiving an assignment message through which a traffic channel is assigned for communication with a network.

23. The method of claim 20, wherein the information of the at least one service type included in the service message transmitted from the first MS is stored by a network.

24. The method of claim 20, wherein multimedia services include communication of audio and at least one of still image, animation, avatar, and emoticon.

25. The method of claim 20, wherein the response message is received via a traffic channel.

26. The method of claim 20, further comprising establishing connection with the second MS using the selected service type upon receipt of a command from the network to establish connection.

27. The method of claim 20, further comprising transmitting a change service message to the second MS to request for communication using a different service type during the connected state.

28. The method of claim 28, wherein the change service message includes information of at least one service type.

29. A method of communicating with at least one mobile station (MS) for establishing service connection in a mobile communication system, the method comprising:

receiving from at least one MS a service message which includes information of at least one service type supported by a first MS and a second MS, wherein the at least one service type relates to a multimedia service supported by each of the first MS and the second MS;

receiving a request message which includes information of at least one service type selected by the first MS;

transmitting a paging request message to the second MS, wherein the paging request message includes the at least one service type selected by the first MS;

receiving a paging response message;
