Server and communication terminal

摘要

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.

主权项

1. A communication terminal for performing communication with a predetermined communication device through a network, comprising one or more hardware components configured to:
receive, by the communication terminal, a control message from the network, the control message being generated based on a trigger request message and being transmitted to the communication terminal, the trigger request message being transmitted from the predetermined communication device and being for requesting transmission of the control message; determine, by the communication terminal, whether to perform the communication with the predetermined communication device using an IP packet; acquire, by the communication terminal, a trigger payload included in the trigger request message; determine, by the communication terminal, whether data is included in the trigger payload; when no data is included in the trigger payload, acquire, by the communication terminal, 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; insert the IP address into the trigger payload; and transmit, by the communication terminal, a response message, the response message being transmitted to the network in response to the control message, where the response message includes the acquired IP address.
