Abstract
To provide a communication system capable of easily selecting group communication to participate in halfway. A communication system according to the present disclosure includes a communication terminal and a server that controls group communication among a plurality of communication terminals. The communication terminal includes: an acquisition unit that acquires information regarding group communication that has already been started among the plurality of communication terminals and is in a non-answered state due to no answer at the start; a selection unit that selects any one from one or more group communications that are candidates for participation based on the acquired information; and a transmission unit that transmits a participation request for the selected group communication to the server. The server includes a participation acceptance unit that accepts participation of the communication terminal in the selected group communication.
