Abstract
A communication device searches for a desired communication device and requests a service, without being conscious of the status of the power supply of other communication devices on a network, and achieves a reduction in power consumption. The communication device includes a main processing unit to process main service provided for other communication devices, a network processing unit to transmit and receive a request packet and a response packet among other communication devices, and an integrated power supply unit to stop supplying power to the main processing unit in a state of being able to supply it again and to supply the power to the network processing unit. The network processing unit is provided with an automatic responding unit to determine whether or not it can respond to the received request packet only by itself and, when the response is possible, to transmit the response packet to the communication device, and a power supply controlling unit, when the response is not possible, to control a main-power supply unit to supply the power to the main processing unit.
