Abstract

A system and method for providing a service in a communication system are provided, in which upon receipt of a request for provisioning of the service with a requested QoS class from an MS, a service server transmits a QoS information request message to an interface server and, upon receipt of a QoS information response message for the QoS information request message from the interface server, the service server provides the service with the requested QoS class to the MS.

Claims

1. A system for providing a service in a communication system, comprising:

a service server for, upon receipt from a Mobile Station (MS) of a request for a provisioning of a service with a requested Quality of Service (QoS) class, transmitting a QoS information request message to an interface server and, upon receipt from the interface server of a QoS information response message for the QoS information request message, providing to the MS the service with the requested QoS class, and

an interface server for receiving from a service server information about a Quality of Service (QoS) class requested for the service by a Mobile Station (MS), acquiring information indicating support of the requested QoS class, and providing the QoS support information to the service server.

2. The system of claim 1, wherein when the service server provides the service with the requested QoS class to the MS, the service server charges the MS for the service at the requested QoS class.

3. The system of claim 1, wherein when the service server determines to change the QoS class of the service after providing the service, the service server transmits to the interface server a service request message requesting a QoS change.

4. The system of claim 1, wherein when the service server determines to terminate the service with the requested QoS class, the service server transmits to the interface server a service termination request message requesting deletion of a recording of the QoS class.

5. The system of claim 4, wherein when the service server transmits a billing information request message requesting storage of billing information about the service with the QoS class, after transmitting the service termination request message.

6. The system of claim 1, wherein when the interface server provides the QoS support information to the service server, the interface server transmits billing information about the service with the requested QoS class to a billing server.

7. The system of claim 1, wherein when the interface server determines to change the QoS class of the service after providing the QoS support information to the service server, the interface server determines whether a valid period of the supported QoS class has expired or an allocated amount of traffic has been exceeded.

8. The system of claim 7, wherein if the valid period of the supported QoS class has expired or the allocated amount of traffic has been exceeded, the interface server one of transmits information about a new supported QoS class to the service server and notifies the service server that no further QoS class can be supported.

9. A method for providing a service in a service server in a communication system, comprising:

transmitting a QoS information request message to an interface server, upon receipt of a request for provisioning of the service with a requested Quality of Service (QoS) class from a Mobile Station (MS); and

providing the service with the requested QoS class to the MS, upon receipt of a QoS information response message for the QoS information request message from the interface server.

10. The method of claim 9, further comprising charging the MS for the service with the requested QoS class.

11. The method of claim 9, further comprising transmitting a service request message requesting a QoS change to the interface server, when it is determined to change the QoS class of the service.

12. The method of claim 9, further comprising transmitting to the interface server a service termination request message requesting deletion of a recording of the QoS class, when it is determined to terminate the service with the requested QoS class.

13. The method of claim 12, further comprising transmitting a billing information request message requesting storage of billing information about the service with the QoS class, after transmitting the service termination request message.

14. A method for providing a service in an interface server in a communication system, comprising:

receiving information about a Quality of Service (QoS) class requested for the service by a Mobile Station (MS) from a service server; and

acquiring information indicating support of the requested QoS class, and providing the QoS support information to the service server.

15. The method of claim 14, further comprising transmitting billing information about the service with the requested QoS class to a billing server.

16. The method of claim 14, further comprising determining if a valid period of the supported QoS class has expired or an allocated amount of traffic has been exceeded, when it is determined to change the QoS class of the service after providing the QoS support information to the service server.

17. The method of claim 16, further comprising, if the valid period of the supported QoS class has expired or the allocated amount of traffic has been exceeded, performing one of transmitting information about a new supported QoS class to the service server and notifying the service server that no further QoS class can be supported.

18. A method for providing a service in a service server in a communication system, comprising:

receiving a request for requesting the service from a Mobile Station (MS) over an access network to which the MS is connected;

identifying the access network of the MS and determining a Quality of Service (QoS) class supported over the access network; and

notifying the MS of the supported QoS class.

19. The method of claim 18, wherein the identification comprises determining if the access network can be supported by an interface.

20. The method of claim 19, wherein the determination comprises comparing an Internet Protocol (IP) address of the access network with IP addresses of networks that the interface can support.

21. The method of claim 19, wherein the QoS determination comprises determining a QoS class supported by a QoS server by means of the interface.

22. A system for providing a service in a communication system, comprising:

a service server for receiving a request for requesting the service from a Mobile Station (MS) over an access network to which the MS is connected, identifying the access network of the MS and determining a Quality of Service (QoS) class supported over the access network, and notifying the MS of the supported QoS class; and

the MS for receiving the service with the supported QoS class from the service server.

23. The system of claim 22, wherein the service server identifies if the access network can be supported by an interface.

24. The system of claim 23, wherein the service server compares an Internet Protocol (IP) address of the access network with IP addresses of networks that the interface can support.

25. The system of claim 23, wherein the service server determines a QoS class supported by a QoS server by means of the interface.
