ABSTRACT:
Messages with a valid range are selected by a message filter unit among the messages received through a network by a message reception unit, and the selected messages with a valid range are temporarily stored in a message storage unit. A message delivery assessment unit compares periodically the valid range of the stored message with a valid range with a current position obtained by a positioning unit, and a message delivery unit delivers the message with a valid range for which the current position is in the valid range, to a user. As a result, the message reception device can deliver the message valid in a specific location to the user with an appropriate timing.
