Abstract

An apparatus and method for selecting a QoS in a portable communication system are provided. The method includes, when using a high quality video communication service, sending a request for the high quality video communication service to a destination terminal using a Circuit Service Data (CSD) channel, receiving a reply message to the high quality video communication service request and, when the reply message is an acceptance of an execution of the high quality video communication service, disconnecting the CSD channel and then connecting a Packet Service Data (PSD) channel, and providing the high quality video communication service using the PSD channel.

Claims

1. A method for providing a video communication service having a selectable Quality of Service (QoS) in a portable terminal, the method comprising:

when using a high quality video communication service, sending a request for the high quality video communication service to a destination terminal using a Circuit Service Data (CSD) channel;

receiving a reply message to the high quality video communication service request and, when the reply message is an acceptance of an execution of the high quality video communication service, disconnecting the CSD channel and then connecting a Packet Service Data (PSD) channel; and

providing the high quality video communication service using the PSD channel.

2. The method of claim 1, wherein sending the high quality video communication service request to the destination terminal further comprises:

transmitting information of a terminal sending a high quality video communication service request, to a video communication server; and

transmitting, by the video communication server, a high quality video communication service request message to the destination terminal, and wherein the information of the terminal sending the high quality video communication service request comprises at least one of a phone number, an Internet Protocol (IP), and information on an execution or non-execution of a QoS communication.

3. The method of claim 2, wherein, upon receiving the high quality video communication service request message from the video communication server, the destination terminal outputs the request message and then identifies if the high quality video communication service is executed by a user.

4. The method of claim 3, wherein, upon receiving the high quality video communication service request message from the video communication server, the destination terminal transmits information of the destination terminal to the video communication server when identifying that a notification of an execution of the high quality video communication service is input from the user.

5. The method of claim 1, further comprising:

when the reply message is a rejection of an execution of the high quality video communication service,

transmitting an execution or non-execution of a high quality video communication service to the video communication server; and

performing a video communication using the CSD channel.

6. A portable terminal for providing a video communication service having a selectable Quality of Service (QoS), the terminal comprising:

a memory for storing user information of a terminal sending a request for a high quality video communication service and information on a notification of an execution or non-execution of a video communication of the terminals; and

a controller for, when using a high quality video communication service, sending a request for the high quality video communication service to a destination terminal using a Circuit Service Data (CSD) channel and then, when receiving a message of a notification of an execution of a high quality video communication service as a reply message to the request, disconnecting the CSD channel and then connecting a Packet Service Data (PSD) channel to allow the use of the high quality video communication service.

7. The terminal of claim 6, wherein the controller transmits information of the terminal sending the request for the high quality video communication service, to a video communication server, transmits, by the video communication server, a high quality video communication service request message to a destination terminal, and requests the destination terminal to provide the high quality video communication service, and

wherein the information of the terminal sending the high quality video communication service request comprises at least one of a phone number, an Internet Protocol (IP), and information on an execution or non-execution of a QoS communication.

8. The terminal of claim 7, wherein, upon receiving the high quality video communication service request message from the video communication server, the destination terminal outputs the request message and then identifies if the high quality video communication service is executed by a user.

9. The terminal of claim 8, wherein, upon receiving the high quality video communication service request message from the video communication server, the destination terminal transmits information of the destination terminal to the video communication server when identifying that a notification of an execution of the high quality video communication service is input from the user.

10. The terminal of claim 6, wherein the controller sends a request for a high quality video communication service to the destination terminal and then, when receiving a notification of a rejection of a high quality video communication service as a reply message to the request, transmits an execution or non-execution of a high quality video communication service to the video communication server and then performs a video communication using the CSD channel.

11. A video communication server for providing a video communication service having a selectable Quality of Service (QoS), the server comprising:

a memory for storing user information of a portable terminal sending a request for a high quality video communication service and information on a notification of an execution or non-execution of a video communication of the terminals; and

a server controller for, when receiving information for requesting a high quality video communication service from the portable terminal, storing and updating user information of the portable terminal and information for notifying an execution or non-execution of a high quality video communication of the terminals in the memory, and transmitting user information of a destination terminal to each terminal when the terminals perform a high quality video communication.

12. A method for providing a video communication service having a selectable QoS in a portable communication system, the method comprising:

means for disconnecting a connected CSD channel and establishing a communication connection over a PSD channel, when receiving a high quality communication request from a destination terminal; and

means for receiving user information and information on an execution or non-execution of video communication of at least one of the origination and destination terminal from at least one of the origination and destination terminal and updating a high quality communication information record, when receiving a high quality communication information request from the at least one of the origination and destination terminal

13. A computer-readable recording medium having recorded thereon a program providing a video communication service having a selectable QoS in a portable communication system, comprising:

a first segment, for disconnecting a connected CSD channel and establishing a communication connection over a PSD channel, when receiving a high quality communication request from a destination terminal; and

a second segment, for receiving user information and information on an execution or non-execution of video communication of at least one of the origination and destination terminal from at least one of the origination and destination terminal and updating a high quality communication information record, when receiving a high quality communication information request from the at least one of the origination and destination terminal
