<p><P>PROBLEM TO BE SOLVED: To provide a communication system and a communication method in which switching of application is interlocked with switching of a transmission path dependent on variation in communication situation incident to movement of a user in mobile environment. <P>SOLUTION: Variation in communication situation incident to movement of a user is monitored constantly and the transmission path is switched as the state of the transmission path varies. State of the transmission path between its own terminal and a communication partner terminal is acquired using the control message of mobile IP, and compared with the priority reference of every application. Consequently, a transmission path suitable for application can be selected and a service can be provided depending on the communication situation by performing alteration to a content suitable for the transmission path simultaneously. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
