Abstract

The present invention relates to a method for changing service quality of a content adaptively. When service quality updating action for a connection is received the present method invokes an action, used for requesting allowance of a new access to a network, to a device conducting traffic transfer services in order that service quality of the connection may be changed. The invoked action carries input arguments including traffic descriptor of the connection, carried by the service quality updating action, which a traffic handle for identifying the traffic descriptor uniquely has been allocated in.

Claims

1. A method for changing service quality of a connection for traffic, comprising:

receiving a request for updating service quality of a connection; and

invoking an action, used for requesting allowance of a new access, to a device conducting traffic transfer service so that service quality of the connection is changed,

wherein the action includes in input argument thereof a traffic descriptor of the connection accompanied by the request for updating, and the traffic descriptor has an identifier identifying the traffic descriptor uniquely.

2. The method of claim 1, wherein, if the device receives an action for requesting allowance of an access including in an input argument thereof a traffic descriptor having a pre-registered identifier, the action is regarded as a request for changing service quality of a currently established connection, and if the device receives an action for requesting allowance of access including in an input argument thereof a traffic descriptor having a not-registered identifier, the action is regarded as a request for establishing a new connection to satisfy service quality requested by the traffic descriptor.

3. The method of claim 2, wherein, in case that the device regards an action for requesting allowance of an access as a request for establishing a new connection, the device registers a traffic handle included in a traffic descriptor accompanied by the action.

4. The method of claim 1, wherein the action further includes in an input argument thereof identifying information on resources of the device to conduct traffic transfer service.

5. The method of claim 1, further comprising,

receiving an action for requesting establishment of a connection;

and

assigning a unique identifier to a traffic descriptor received from the action and incorporating the unique identifier into the traffic descriptor, and requesting the device for allowance of an access with service quality required by the traffic descriptor.

6. The method of claim 1, wherein, according to the request, the device adjusts bandwidth allocated to the connection to be suitable for requested service quality without release of the connection and reconfiguring to a specified service rate.

7. The method of claim 1, wherein the request for updating service quality of a connection is made according to occurrence of an event notifying of degrading service quality of the connection.

8. The method of claim 7, wherein the event is generated when the device does not admit a request for allowance of access for a new connection.

9. The method of claim 7, wherein the degrading of service quality is from HD (High Definition) to SD (Standard Definition)

10. The method of claim 1, wherein the request for updating service quality of a connection is made according to occurrence of an event notifying of availability of bandwidth.

11. The method of claim 10, wherein the event is generated when an existing connection is released.

12. The method of claim 10, wherein the request for updating is a request for changing service quality of the connection from SD (Standard Definition) to HD (High Definition).

13. The method of claim 1, wherein the connection, where the request for updating service quality is made, is selected by a management device managing allowance of access to a network.

14. The method of claim 1, wherein the connection, where the request for updating service quality is made, is selected by a control application for controlling multiple devices and/or services connected to a network.
