Abstract

Disclosed is a method of managing a connection with a device for a wireless communication-based Wireless universal Serial Bus (WSB) service in a host, including controlling to create an initial channel to connect to a target device for a WSB service, considering a device class of the target device, and configured to create a new channel to substitute for the initial channel considering a particular service, at a user'"'"'s request, to provide the particular service through association with the target device.

Claims

1. A method of managing a connection with a device for a wireless communication-based Wireless universal Serial Bus (WSB) service in a host, the method comprising:

creating an initial channel to connect to a target device for a WSB service, considering a device class of the target device; and

creating a new channel to substitute for the initial channel considering a particular service, at a user'"'"'s request, to provide the particular service through connection with the target device.

2. The method of claim 1, further comprising creating a third channel to substitute for the new channel considering another service, at a request to provide the another service through association with the target device.

3. The method of claim 2, wherein the initial channel, the new channel, and the third channel have at least one of service quality and bandwidth different from one another.

4. The method of claim 3, further comprising creating a session with the target device on the new channel or on the third channel.

5. The method of claim 1, wherein creating the initial channel comprises:

sending a probe request message to the target device;

receiving a probe response message in response to the probe request message;

identifying a device class of the target device from the probe response message; and

creating an initial channel to satisfy service quality that matches the device class.

6. The method of claim 5, wherein creating the new channel comprises:

monitoring whether a particular service is requested to be provided through connection with the target device after the initial channel is created;

requesting the target device to provide information about the particular service, if the particular service is requested to be provided;

receiving the information about the particular service in response to the request;

determining service quality for the particular service based on the information about the particular service; and

creating a new channel to satisfy the determined service quality.

7. The method of claim 6, wherein when the particular service is a playing service of a particular video, the information about the particular service is metadata of the particular video.

8. The method of claim 6, further comprising releasing the initial channel.

9. A device for providing a wireless communication-based Wireless universal Serial Bus (WSB) service in a host, the device comprising:

a controller configured to control to create an initial channel to connect to a target device for a WSB service, considering a device class of the target device, and configured to create a new channel to substitute for the initial channel considering a particular service, at a user'"'"'s request, to provide the particular service through association with the target device; and

a channel create unit configured to create the initial channel and the new channel under control of the controller.

10. The device of claim 9, wherein the controller detects that another service is requested to be provided through association with the target device after the new channel is created, and controls the channel create unit to create a third channel to substitute for the new channel, considering the another service.

11. The device of claim 10, wherein the initial channel, the new channel, and the third channel have at least one of service quality and bandwidth different from one another.

12. The device of claim 11, wherein the controller controls the channel create unit to create a session with the target device on the new channel or the third channel.

13. The device of claim 9, wherein the controller sends a probe request message to the target device, receives a probe response message in response to the request probe message, identifies a device class of the target device from the probe response message, and controls the channel create unit to create an initial channel to satisfy service quality that matches the device class.

14. The device of claim 13, wherein the controller monitors whether a particular service is requested to be provided through connection with the target device after the initial channel is created, requests the target device to provide information about the particular service, if the particular service is requested to be provided, receives the information about the particular service in response to the request, determines service quality for the particular service based on the information about the particular service, and controls the channel create unit to create a new channel to satisfy the determined service quality.

15. The device of claim 14, wherein when the particular service is a playing service of a particular video, the information about the particular service is metadata of the particular video.

16. The device of claim 14, wherein the controller controls the channel create unit to release the initial channel if the new channel is created.
