Abstract
It is an object of the present invention to provide a communication system to provide a communication system which requires no special application for a correspondent node and has a service handoff function enabling a transfer destination terminal device to be freely used, and its configuration equipment.In order to realize this, the communication system includes a correspondent node delivering communication data which can be executed by a predetermined application, a proxy server device which receives the communication data from the node to execute the application, and transfers the service to a transfer destination terminal device, the transfer destination terminal device outputting the service, and a user terminal device, wherein the user terminal device transmits control information to the proxy server device, and thereby the proxy server device switches the transfer destination terminal device to perform service handoff.
