Abstract
The present invention relates to a slave communication device 2 in a wireless LAN system in which a single wireless channel is used, and when a telephone apparatus outside the network originates a call to the LAN, the originated call once terminates at the master communication device and wireless telephone communication can be established between that telephone apparatus and a slave communication device by themselves through a host station without relaying through the master communication device, and does not require particular processing such as authentication on the host station side. To switch between a first state in normal times in which a transmission/reception means 5 of a master communication device 1 is turned on and transmission/reception means 5 of respective slave communication devices 2 are turned off and a second state at the time of control delegation in which the transmission/reception means 5 of the master communication device 1 is turned off and only the transmission/reception means 5 of any one of the slave communication devices which is a subject of control delegation is turned on, a control means 6 of the slave communication device 2 normally turns off the transmission/reception means 5 to be in an output prohibited state in which output of a radio signal is prohibited, and turns on the transmission/reception means 5 to enter an output permitted state in which a radio signal is output using the wireless telephone line when a short-range wireless communication means 4 receives a terminating control delegation signal transmitted from the master communication device 1 destined for itself in association with occurrence of a reason of terminating control delegation during wireless telephone communication between the master communication device 1 and a telephone apparatus outside the network, and controls the transmission/reception means 5 to again turn off the transmission/reception means 5 to return to the output prohibited state when a control delegation completion reason occurs in the output permitted state.
