Abstract

Disclosed is a technique for reporting the IP address of a UE using a response message to a device trigger. A control message receiving unit receives, from a network, a control message generated based on a trigger request message transmitted from the predetermined communication device for requesting the transmission of the control message to a communication terminal. A determining unit determines whether to perform communication with the predetermined communication device using an IP packet. A connection management unit acquires an IP address allocated to an IP connection used in communication with the predetermined communication device when determining to perform the communication using the IP packet at the time of receiving the control message at the control message receiving unit. A response message transmitting unit transmits a response message to the control message to the network, where the response message includes the IP address acquired by the connection management unit.

Claims

1. A communication terminal for performing communication with a predetermined communication device through a network, comprising:

a control message receiving unit for receiving, from the network, a control message generated based on a trigger request message transmitted from the predetermined communication device for requesting transmission of the control message to the communication terminal;

a determining unit for determining whether to perform the communication with the predetermined communication device using an IP packet;

a connection management unit for acquiring an IP address allocated to an IP connection used in the communication with the predetermined communication device when determining to perform the communication using the IP packet at the time of receiving the control message at the control message receiving unit; and

a response message transmitting unit for transmitting a response message to the control message to the network, where the response message includes the IP address acquired by the connection management unit.

2. The communication terminal according to claim 1, wherein upon acquiring the IP address, the connection management unit newly establishes an IP connection when the IP connection has not been established.

3. The communication terminal according to claim 1, wherein the response message transmitting unit inserts the IP address into a field in which application information in the response message is set.

4. The communication terminal according to claim 1, wherein when no application data is included in the control message, the response message transmitting unit determines to perform the communication using the IP packet.

5. The communication terminal according to claim 1, wherein when the communication terminal has application data to be transmitted to the predetermined communication device, the response message transmitting unit determines to perform the communication using the IP packet.

6. A server for mediating communication between a communication terminal and an application server, comprising:

a trigger request transmitting unit for transmitting a trigger request to a network node to request transmission of a control message to the communication terminal when data is acquired from the application server;

a report receiving unit for receiving a report message including an IP address from the network node that received a response message including the IP address of the communication terminal, where the response message is a response message to the control message transmitted from the network to the communication terminal based on the trigger request, and acquiring the IP address of the communication terminal included in the report message; and

a communication terminal information holding unit for holding the IP address and identification information on the communication terminal in association with each other.

7. The server according to claim 6, wherein the IP address is inserted in a field in which application information of the report message is set.

8. The server according to claim 6, further comprising an IP packet receiving unit for reporting a payload included in an IP packet to the application server when the source address of the received IP packet matches an IP address held in the communication terminal information holding unit.
