Abstract

The present invention relates to a slave communication device in a wireless LAN system which allows each slave communication device to perform originating to a telephone apparatus outside a network by itself through a host station without relaying through a master communication device while a single wireless telephone line is used, 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 an originating control delegation signal for permitting originating by the transmission/reception means using an ID of the wireless telephone line transmitted from the master communication device 1 destined for itself in association with occurrence of a reason of originating control delegation, 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.
