In a case where a PTT start notification is received at a communication part 102, a PTT application for executing processing concerning PTT communication is started up, and an instruction for starting the PTT communication is not input to a key input part 103 for a predetermined time, the PTT application automatically ends and predetermined flag data fg is stored in an external data storage region AR1. After that, when the PTT application is not started up, a notification of reception of an absent signal indicating no reply to the PTT start notification is reported based on the flag data fg stored in the external data storage region AR1. Further, in an automatic reply mode, when PTT communication which automatically started in response to the PTT start notification ends, the reception of a PTT communication start notification of no reply, that is, reception of an absent signal, is suitably reported to a user based on presence/absence of transmission of information from the communication part 102 in the communication apparatus itself at a and input of an instruction at the key input part 103. |
