摘要

PROBLEM TO BE SOLVED: To continue communication even when the communication address of one communication equipment is changed during communication.

SOLUTION: At the time of establishing a session with a server 1, a client 2 transmits session ID to identify the established session and the communication address of the client 2 to the server 1. The server 1 is provided with a session information storing part 15 in which the session ID for identifying the session established with the client 2 and the communication address of the client 2 are stored so as to be associated with each other, and configured to update contents of the session information storing part 15 based on the session ID and the communication address received from the client 2. The server 1 generates and transmits transmission data to the client 2 concerning a certain session by acquiring the communication address associated with the session ID of the session from the session information storing part 15.
