Abstract:
Provided is a communication system capable of releasing a tunnel while securing mobility without securing resources in an SGW or the like. A first node provided in a communication system that provides mobility of packet data using tunneling includes: a tunnel control unit that releases a tunnel and deletes tunnel information; and a management unit that associates and manages an IP address allocated to a terminal to which the tunnel is established and subscriber identification information of the terminal when the tunnel is released and the tunnel information is deleted.
