Abstract
A communication control unit controls communication between a terminal and a communication network employing a multi-conjunction architecture, and comprises a transmitter/receiver for transmitting and receiving a signal to and from the communication network, a switch part for enabling signal transmission and reception between the terminal and the communication network through the transmitter/receiver in a first state and for disabling the signal transmission and reception between the terminal and the communication network through the transmitter/receiver in a second state, and a control part comprising a signal detecting circuit for detecting whether or not a signal received from the communication network through the transmitter/receiver is intended for the terminal coupled to the communication control unit. The control part controls the switch part to the first state when the signal detecting circuit detects that the signal received from the communication network through the transmitter/receiver is intended for the terminal coupled to the communication control unit.
