<p>Networks are allowed to share information of devices the communication of which should be rejected. A communication device, which exists in a first network, registers information for identifying a device the communication of which should be rejected, and then notifies the registered information to the other devices existing in the first network. Further, the communication device and the other devices constitute a second network that is different from the first network where the device the communication of which should be rejected exists.</p> |
