Abstract

Provided is a technique whereby a device can be shared efficiently by multiple hosts in a network having a host as a control apparatus and a device has a controlled apparatus. A communication system that includes a wireless apparatus having a host function in which the wireless apparatus serves as a control apparatus and a device function in which the wireless apparatus serves as a controlled apparatus constructs a first network in which a first wireless apparatus serves as a host and a second wireless apparatus serves as a device, and constructs a second network in which the first wireless apparatus serves as a device and the second wireless apparatus serves as a host based upon a connection request transmitted from the second wireless apparatus to the first wireless apparatus via the first network.

Claims

1. A method of configuring a network of a communication system comprising a wireless apparatus having a host function in which the wireless apparatus serves as a control apparatus and a device function in which the wireless apparatus serves as a controlled apparatus, and wherein

a first wireless apparatus for configuring a first network wherein the first wireless apparatus serves as a host and a second wireless apparatus serves as a device, and for configuring a second network, wherein the first wireless apparatus serves as a device and the second wireless apparatus serves as a host, based upon a connection request transmitted from the second wireless apparatus to the first wireless apparatus via the first network.

2. The method according to claim 1, wherein the first wireless apparatus transmits a signal for indicating that the first wireless apparatus is not connectable via the first network while communication via the second network is in progress.

3. The method according to claim 1, wherein the second network is disconnected after data communication via the second network is terminated.

4. The method according to claim 1, wherein after data communication via the second network is terminated, the first wireless apparatus transmits a signal for indicating that the first wireless apparatus is connectable via the first network.

5. The method according to claim 1, wherein even if data communication via the second network is terminated, the second network is maintained until a connection request of the second network is transmitted via the first network.

6. The method according to claim 1, wherein if the first wireless apparatus receives a second-network connection request from a third wireless apparatus via the first network while the first wireless apparatus is communicating with the second wireless apparatus via the second network, the first wireless apparatus transmits a signal for indicating that connection is not possible, to the third wireless apparatus via the first network.

7. The method according to claim 1, wherein if the first wireless apparatus receives a connection request of the second network via the first network while the first wireless apparatus is communicating with the second wireless apparatus via the second network, the first wireless apparatus registers the apparatus that transmitted said connection request,

the first wireless apparatus disconnects the second wireless apparatus and the second network after communication with the second wireless apparatus via the second network is terminated and

the first wireless apparatus configures a second network, in which the registered apparatus serves as a host and the first wireless apparatus serves as a device, after the second network is disconnected.

8. A communication system including a wireless apparatus having a host function in which the wireless apparatus serves as a control apparatus and a device function in which the wireless apparatus serves as a controlled apparatus, wherein a first wireless apparatus and a second wireless apparatus comprising:

a first construction unit for configuring a first network wherein the first wireless apparatus serves as a host and the second wireless apparatus serves as a device; and

a second construction unit for configuring a second network, wherein the first wireless apparatus serves as a device and the second wireless apparatus serves as a host, based upon a connection request transmitted from the second wireless apparatus to the first wireless apparatus via the first network.

9. A wireless apparatus which is a first wireless apparatus having a host function in which the first wireless apparatus serves as a control apparatus and a device function in which the first wireless apparatus serves as a controlled apparatus, comprising:

a host unit for configuring a first network wherein the first wireless apparatus serves as a host and another wireless apparatus serves as a device; and

a device unit for configuring a second network wherein a second wireless apparatus that transmitted a connection request to the first wireless apparatus via the first network serves as a host and the first wireless apparatus services as a device.

10. A wireless apparatus which is a second wireless apparatus having a host function in which the second wireless apparatus serves as a control apparatus and a device function in which the second wireless apparatus serves as a controlled apparatus, comprising:

a device unit for configuring a first network wherein a first wireless apparatus serves as a host and the second wireless apparatus serves as a device;

a request unit for requesting configuration of a second network, via the first network, wherein the first wireless apparatus serves as a device and the second wireless apparatus serves as a host; and

a host unit for configuring the second network.
