ABSTRACT:
A communicating apparatus for performing a communication through a plurality of communication channels including a control channel is constructed by a detection unit to detect a hold request and a transmission unit to transmit a channel switch command to a terminal in a waiting state by the control channel. The transmitting unit transmits the channel switch command such that the terminal waits and responds to a held communication in a state where the terminal is switched from the control channel during a holding state.
