Abstract
In a communication system 10, an IN-CSE 200 maps and retains a public IP address acquired from an MTC-UE 100 and an UE-ID, and receives an incoming message addressed to the MTC-UE 100 from an AS 40A. The IN-CSE 200, 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/PGW 310 an IP packet containing the corresponding UE-ID. The GGSN/PGW 310 identifies a private IP address assigned to the MTC-UE 100, based on the UE-ID included in the IP packet received from the IN-CSE 200.
