Abstract

PURPOSE:To economically transfer an incoming call to moving equipment to another moving equipment which is far from the first-mentioned moving equipment, by preparing (n) lines of wire telephone lines and (n+1) sets of host-side radiotelephone equipment when (m) sets of moving equipment are used, with the (n) being smaller than (m). CONSTITUTION:After sending a talking channel number CH signal, host equipment switches the channel to the talking channel designating radiotelephone equipment 4. If an incoming call arrives at another wire telephone line at this moment, the host equipment 1 sends a CH signal through a channel for control by using another radiotelephone equipment 5 corresponding to the line. Upon receiving the CH signal again while calling, each moving equipment reads out a channel number again from the CH signal and stores the channel number in the 2nd place of a CH memory 12. After sending the CH signal, the host equipment 1 switches the channel to the channel designating the equipment 5. Moving equipment 16 selects the 1st circuit, is set to the off-hooked state, sends a response signal by using the 1st channel of a CH memory, stops a bell, and connects its handset 10 with the radiotelephone equipment 4. upon receiving the response signal, the host equipment 1 connects the radiotelephone equipment 4 with a wire telephone line 1.
