Method and system for message propagation to a portable terminal

摘要

An information propagation system allowing information notification destinations to fall within a certain range proximate to an information providing source without limiting the destinations to those in contact with the source and without expanding the destinations to many and unspecified destinations is provided. A fixed station or a portable information terminal transmits a message and a message transfer frequency to a portable information terminal. The portable information terminal transfers the message to a portable information terminal and subtracts the message transfer frequency by one, and further transfers the message to a portable information terminal and subtracts the message transfer frequency by one. The portable information terminal finishes transferring the message when the message transfer frequency reaches zero. The portable information terminal transfers the received message to a portable information terminal and subtracts the message transfer frequency by one. The portable information terminal also finishes transferring the message when the message transfer frequency reaches zero.
