Abstract

A server device for transmitting and receiving data to and from a client device over a wireless communication network including an access point, the server device comprising: wireless connection determining means for determining whether or not the client device is wirelessly communicatively connected over the wireless communication network; security determining means for determining whether or not the client device is securely connected to the access point; and permitting means for permitting an automatic connection of the client device to the server device, when the wireless connection determining means determines that the client device is wirelessly communicatively connected, and when the security determining means determines that the client device is securely connected to the access point.

First claim

The invention claimed is:

1. A server device for transmitting and receiving data to and from a client device through an access point, the server device comprising:
a first determining unit configured to determine whether or not the client device is wirelessly connected to the access point, based on reception of a signal from the client device, the signal having an argument indicating an encryption method used in a communication between the client device and the access point;
a second determining unit configured to determine whether or not the client device is securely connected to the access point, based on the argument of the signal; and
a third determining unit configured to determine whether or not to allow a connection from the client device to the server device through the access point, based on results of determination of the first and second determining units.

2. The server device according to claim 1 ,
wherein, when the first determining unit determines that the client device is wirelessly connected to the access point, and the second determining unit determines that the client device is securely connected to the access point, the third determining unit permits an automatic connection of the client device to the server device through the access point.

3. The server device according to claim 2 , further comprising a registering unit configured to register the client device as an accessible device when the third determining unit permits the automatic connection.

4. The server device according to claim 2 ,
wherein when permitting the automatic connection, the third determining unit permits the client device to play a content stored in the server device.

5. The server device according to claim 3 ,
wherein when the first determining unit determines that the client device is not wirelessly connected to the access point, or when the second determining unit determines that the client device is not securely connected to the access point, the third determining unit displays a screen for asking a user whether or not the client device is to be registered with the registering unit.

6. The server device according to claim 1 ,
wherein when the first determining unit determines that the client device is not wirelessly connected to the access point, or when the second determining unit determines that the client device is not securely connected to the access point, the third determining unit displays a warning message on a display screen.

7. The server device according to claim 1 , further comprising a unit configured to transmit, to at least one of the access point and the client device, a command to instruct setting of an encrypted communication between the access point and the client device, when the first determining unit determines that the client device is not wirelessly connected to the access point, or when the second determining unit determines that the client device is not securely connected to the access point.

8. The server device according to claim 1 , further comprising a client detecting unit configured to detect the client device in accordance with a UPnP architecture,
wherein the first determining unit and the second determining unit perform processes of the determination for the client device detected by the client detecting unit, respectively.

9. A method for connecting a server device to a client device through an access point, the method including:
a first determining step for determining whether or not the client device is wirelessly connected to the access point, based on reception of a signal from the client device, the signal having an argument indicating an encryption method used in a communication between the client device and the access point;
a second determining step for determining whether or not the client device is securely connected to the access point, based on the argument of the signal; and
a third determining step for determining whether or not to allow a connection from the client device to the server device through the access point, based on results of determination of the first and second determining steps.

10. The method according to claim 9 ,
wherein, when the first determining step determines that the client device is wirelessly connected to the access point, and the second determining step determines that the client device is securely connected to the access point, the third determining step includes permitting an automatic connection of the client device to the server device through the access point.

11. The method according to claim 10 , further including registering the client device as an accessible device when the third determining step permits the automatic connection.

12. The method according to claim 11 ,
wherein the third determining step includes displaying a screen for asking a user whether or not the client device is to be registered, when the first determining step determines that the client device is not wirelessly connected to the access point, or when the second determining step determines that the client device is not securely connected to the access point.

13. The method according to claim 10 ,
wherein the third determining step includes permitting the client device to play a content stored in the server device, when permitting the automatic connection.

14. The method according to claim 9 ,
wherein the third determining step including displaying a warning message on a display screen, when the first determining step determines that the client device is not wirelessly connected to the access point, or when the second determining step determines that the client device is not securely connected to the access point.

15. The method according to claim 9 , further including transmitting, to at least one of the access point and the client device, a command to instruct setting of an encrypted communication between the access point and the client device, when the first determining step determines that the client device is not wirelessly connected to the access point, or when the second determining step determines that the client device is not securely connected to the access point.

16. The method according to claim 9 , further including detecting the client device in accordance with a UPnP architecture,
wherein the first determining step and the second determining step are performed for the detected client device, respectively.
