Radio communication system and radio communication method

In a communication system, an IN-CSEmaps and retains a public IP address acquired from an MTC-UEand an UE-ID, and receives an incoming message addressed to the MTC-UEfrom an ASA. The IN-CSE, upon receiving the incoming message, sets the public IP address mapped with the retained UE-ID in a destination address, and delivers to a GGSN/PGWan IP packet containing the corresponding UE-ID. The GGSN/PGWidentifies a private IP address assigned to the MTC-UE, based on the UE-ID included in the IP packet received from the IN-CSE
