Abstract

A mobile radio communication system which allows stored messages to be broadcasted to any number of destinations in the mobile radio communication system which allows communication of stored messages, such as electronic mails or voice mails is provided. A broadcast group is previously registered in a second database 26, and if a mail having a destination address corresponding to the broadcast group is received, a message is broadcasted to each of members included in the corresponding broadcast group. At this time, replacing the sender'"'"'s address of the broadcast message with the destination address corresponding to the broadcast group allows the reply message to the broadcast message to be handled as a broadcast message to the same members.
