Abstract:
1. A communication terminal which transmits/receives a frame to/from a management terminal which is connected to a first network, through a second network, the communication terminal comprising: a frame reception section which receives a frame which is transmitted to the management terminal by another communication terminal; a power off section which turns off power of the communication terminal, during a period of power off time determined on the basis of a transmission time indicated by the content of the received frame; a frame content readout section which reads out a content stored in the frame which is received by the frame reception section; a power off time setup section which sets up a power off time for turning off power of the communication terminal, on the basis of the content of the frame which is read out by the frame content readout section, wherein the power off section turns off power of the communication terminal, during a period of the power off time which is set up by the power off time setup section and determined on the basis of the transmission time indicated by the content of the received frame; and a time judgment section which judges whether the power off time, set up by the power off time setup section, exceeds a predetermined time or not, wherein the power off section, in case of a judgment by the time judgment section that the power off time exceeds the predetermined time, turns off power of the communication terminal, during the period of the power off time.
