Abstract

PROBLEM TO BE SOLVED: To reduce an incoming call loss due to a slave set whose power supply is interrupted by reducing power consumption of the slave set caused by periodic confirmation of the arrival of incoming calls in a radio communication equipment consisting of a master set connected to a public network through a radio channel and the slave set connected to this master set through the radio channel. SOLUTION: When the master set 101 receives an incoming call from a public network 104, the master set itself conducts call reception display and informs the slave set 102 of the arrival of the incoming call. When power? of the slave set 102 is turned on, the availability of receiving the incoming call is returned from the slave set 102 to the master set 101, and the master set 101 sends an acknowledgement of the incoming call to the public network 104. Even when the power supply of the slave set 102 is interrupted, the user recognizing the incoming call display of the master set itself turns on the power supply of the slave set 102 to allow the started slave set 102 to confirm the arrival of the incoming call to the master set 101. When the incoming call arrives, the slave set 102 sends the availability of receiving the incoming call to the master set 101 in response to the confirmation. Thus, the master set 101 transmits the acknowledgement of the incoming call to the public network 104.
