Network station and the network connected to the switching unit

摘要

The present invention relates to the field of data transmission in the network (12 to 16) stations dispersed. One of the problems in the UPnP-based network, is that in order for UPnP devices is available in the network, it is necessary to constantly switch on the UPnP device. The present invention has been made to intervene in this point, it is possible that a network station that is not being used is switched off, it describes a method that can be recognized as a device in the network continuously. If the device is switched off is required, the device is switched on automatically. This makes it possible to achieve a considerable power saving network. The present invention provides a (10) network connected to the switching unit comprising "communication means for maintaining" the (22 to 26). Communication maintenance means for maintaining up to a limited degree at least in place of (15) the network station has been deactivated for the communication network stations are deactivated (15). It is proposed network station that meet this also (15).
