    Abstract: PROBLEM TO BE SOLVED: To provide techniques associated with a communication system that operates stably, without being affected by a change of the IP address of a mobile node.
    SOLUTION: In a communication system wherein an application program (410) uses Internet protocol address information to provide a communication session and an operating system (420) monitors the Internet protocol address information and informs the application program of a change of the Internet protocol address information, the application program is configured to adapt the communication session in response to the change of the Internet protocol address information and as a result of causing the operating system to inform the application program of the change of the Internet protocol address information, the application program adapts the action of the communication session so as to reduce the possibility for the communication session to be affected if the IP address is changed.

    Abstract: PROBLEM TO BE SOLVED: To distribute a content and to manage the right of the content, by a method of high cost efficiency. SOLUTION: The system is provided with an application device AD and a smart card access device 22 which accesses a smart card 20, and the system is operable to safely communicate content access data to the smart card 20 via a communication network by encrypting the content access data by using a key KC which is preliminarily stored in the smart card 20 and is known to a trusted server TS, and the smart card 20 decrypts the content access data encrypted by using the key KC, and the system is operable to store the content access data in the smart card 20. In the server TS, a trusted player accesses right management data provided with content access data of the smart card 20 to perform reproduction or the like of the content in accordance with the right management data.
