Abstract
When information is delivered to a receiver mobile communication terminal, an update unit updates delivery status data stored in first storage, from “undelivered” to “delivered” in response to an update request from a relay when check permission data stored in second storage is “permitted.” When in this state a sender terminal issues a check request for the delivery status data, a sending unit sends the delivery status data of “delivered” status to the sender terminal. When the check permission data is set as “prohibited,” the delivery status data is not updated to the delivered status even if the receiver has received the information.
