Abstract

A method and a system are capable of supporting a Quality of Service (QoS) service in a wireless communication system. The method for supporting the QoS service includes checking a service capability of an application; when the application provides a QoS service, requesting QoS configuration to a QoS server; and when receiving a QoS configuration response signal from the QoS server, checking whether QoS of the application is allocated, in the QoS configuration response signal.

Claims

1. A method of a mobile station in a wireless communication system, the method comprising:

transmitting, to a first server included in a communication network to which the mobile station is connected, a request message for a quality of service (QoS) configuration regarding an application installed in the mobile station, wherein the request message comprises information regarding the application; and

performing a procedure for the QoS configuration with a gateway (GW),

wherein the procedure is initiated, by the GW, when a message comprising rule information for the QoS configuration is transmitted from a second server to the GW,

wherein the rule information is generated, by the second server, based on the information regarding the application which is transmitted from the first server, and

wherein the request message is generated by the application and transmitted from an application layer in which the application is installed to the first server via a middleware (MW).

2. The method of claim 1, wherein the request message further comprises at least one uniform resource locator, a protocol, a URL version, a sequence number, a transmission protocol, and a port address.

3. The method of claim 1, further comprising:

if the application provides a voice over internet protocol (VoIP) service, negotiating with a peer of the wireless communication system about a service bandwidth and a codec.

4. The method of claim 1, wherein the first server is connected to a content server generating the application.

5. The method of claim 1, wherein the second server is a policy and charging enforcement function (PCRF), and

wherein the rule information further comprises policy and charging control (PCC) rule.

6. A method of a first server included in a communication network to which a mobile station is connected, the method comprising:

receiving, from the mobile station, a request message for a quality of service (QoS) configuration regarding an application installed in the mobile station, wherein the request message comprises information regarding the application; and

transmitting, to a second server connected to the first server, the information regarding the application upon determining allowance of the QoS configuration,

wherein the information regarding the application is used, by the second server, for generating rule information for the QoS configuration, and

wherein the rule information is used, by a gateway (GW), for initiating a procedure for the QoS configuration with the mobile station,

wherein the request message is generated by the application and transmitted from an application layer in which the application is installed to the first server via a middleware (MW).

7. The method of claim 6, wherein the request message further comprises at least one uniform resource locator, a protocol, a URL version, a sequence number, a transmission protocol, and a port address.

8. The method of claim 6, wherein the first server is connected to a content server generating the application.

9. The method of claim 6, wherein the second server is a policy and charging enforcement function (PCRF), and

wherein the rule information further comprises policy and charging control (PCC) rule.

10. An apparatus of a mobile station in a wireless communication system, the apparatus comprising:

at least one transceiver; and

at least one processor operatively coupled to the at least one transceiver, wherein the at least one processor is configured to;

transmit, to a first server included in a communication network to which the mobile station is connected, a request message for a quality of service (QoS) configuration regarding an application installed in the mobile station, wherein the request message comprises information regarding the application; and

perform a procedure for the QoS configuration with a gateway (GW), wherein the procedure is initiated, by the GW, when a message comprising rule information for the QoS configuration is transmitted from a second server to the GW,

wherein the rule information is generated, by the second server, based on the information regarding the application which is transmitted from the first server, and

wherein the request message is generated by the application and transmitted from an application layer in which the application is installed to the first server via a middleware (MW).

11. The apparatus of claim 10, wherein the request message further comprises at least one uniform resource locator, a protocol, a URL version, a sequence number, a transmission protocol, and a port address.

12. The apparatus of claim 10, wherein, if the application provides a voice over internet protocol (VoIP) service, the at least one processor is configured to negotiate with a peer of the wireless communication system about a service bandwidth and a codec.

13. The apparatus of claim 10, wherein, if the application provides a video on demand (VOD) service, the at least one processor is configured to check video/audio stream information.

14. The apparatus of claim 10, wherein the second server is a policy and charging enforcement function (PCRF), and

wherein the rule information further comprises policy and charging control (PCC) rule.

15. An apparatus for a first server included in a communication network to which a mobile station is connected, the apparatus comprising:

at least one transceiver; and

at least one processor operatively coupled to the at least one transceiver, wherein the at least one processor is configured to;

receive, from the mobile station, a request message for a quality of service (QoS) configuration regarding an application installed in the mobile station, wherein the request message comprises information regarding the application; and

transmit, to a second server connected to the first server, the information regarding the application upon determining allowance of the QoS configuration,

wherein the information regarding the application is used, by the second server, for generating rule information for the QoS configuration,

wherein the request message is generated by the application and transmitted from an application layer in which the application is installed to the first server via a middleware (MW), and

wherein the rule information is used, by a gateway (GW), for initiating a procedure for the QoS configuration with the mobile station.

16. The apparatus of claim 15, wherein the request message further comprises at least one uniform resource locator, a protocol, a URL version, a sequence number, a transmission protocol, and a port address.

17. The apparatus of claim 15, wherein the first server is connected to a content server generating the application.

18. The apparatus of claim 15, wherein the second server is a policy and charging enforcement function (PCRF), and

wherein the rule information further comprises policy and charging control (PCC) rule.
