Abstract
A communication system having a plurality of communication terminals which perform data communication with each other through a communication network. Each communication terminal includes a refusing time zone registration unit for registering a time zone in which the communication terminal will not accept a communication request from the other communication terminals, a present time acquisition unit for acquiring a present time when a communication request is received from a communication request transmitting terminal, and a judgment unit for judging whether the communication request has been received during the registered time zone by comparing the acquired present time to the registered time zone. The communication terminal further includes a communication refusing signal issuance unit for issuing a communication refusing signal automatically to the communication request transmitting terminal when it is judged that the communication request has been received during the registered time zone.
