Abstract

The present application relates to a control function related to a trigger in a communication network for machine-type communication. A method for triggering a terminal comprises the steps of: receiving a trigger request message from a trigger request transmission server which transmits trigger requests from external servers; and transmitting the trigger request message to a terminal using a received short message, wherein transmission parameters of the short message indicates that the received short message is a short message for triggering a machine-type communication (MTC) apparatus.

Claims

1. A trigger request delivery server comprising:

an interface module of a server side configured to receive a terminal trigger request from an external server;

a terminal identifier mapping module configured to map an identifier of the terminal to an IMSI (International Mobile Subscriber Identity) of the terminal; and

an interface module of a short message server side configured to generate a short message using the trigger request and the IMSI of the terminal and transmit the generated short message to a short message server which delivers the short message to the terminal.

2. The trigger request delivery server of claim 1, wherein the terminal identifier mapping module interrogates a HLR/HSS (Home Location Register/Home Subscriber Server) in order to map the identifier of the terminal to the IMSI (International Mobile Subscriber Identity) of the terminal.

3. The trigger request delivery server of claim 1, wherein the trigger request comprises a validity time to store the trigger request in a network when the trigger request is not delivered to the terminal.

4. The trigger request delivery server of claim 3, wherein the validity time is included in a parameter of the short message.

5. The trigger request delivery server of claim 1, wherein the trigger request comprises at least one of an identifier of the external server, the identifier of the terminal, an identifier of an application operated on the terminal and a priority.

6. The trigger request delivery server of claim 1, further comprising an overload determining module configured to determine an overload by managing a number of trigger requests transmitted from a specific external server or a total number of trigger requests transmitted from all external servers.

7. The trigger request delivery server of claim 6, wherein the trigger request comprises information on a priority.

9. The trigger request delivery server of claim 1, wherein the interface module of the short message server side receives a report with success or failure of delivery of the short message from the short message server.

8. (canceled)

10. (canceled)

11. A short message server comprising:

an interface module of a server side configured to receive a trigger request message delivered from a trigger request delivery server configured to deliver the trigger request from an external server; and

an interface module of a terminal side configured to deliver the trigger request message to the terminal using a mobile terminated short message,

wherein a short message transfer layer parameter represents that the mobile terminated short message is a short message for a MTC device triggering.

12. The short message server of claim 11, wherein at least a portion of the trigger request message is mapped to a SMS application layer protocol parameter, a SMS transfer layer protocol parameter, or SMS relay layer protocol parameter.

13. The short message server of claim 11, wherein an application identifier included in the trigger request message is in a TP-UD (Transfer Protocol-User Data) which is a SMS transfer layer protocol parameter.

14. A method for delivering a trigger request in a short message delivery server delivering the trigger request from an external server to a terminal, the method comprising:

receiving the trigger request of the terminal from the external server;

mapping an identifier of the terminal to an IMSI(International Mobile Subscriber Identity) of the terminal; and

transmitting a short message generated using the trigger request and the IMSI of the terminal to a short message server which delivers the short message to the terminal.

15. The method of claim 14, wherein the mapping comprises interrogating a HLR/HSS (Home Location Register/Home Subscriber Server) and so mapping the identifier of the terminal to the IMSI (International Mobile Subscriber Identity) of the terminal.

16. The method of claim 14, wherein the trigger request comprises a validity time to store the trigger request in a network when the trigger request is not delivered to the terminal.

17. The method of claim 16, wherein the validity time is included in a parameter of the short message.

18. The method of claim 14, wherein the trigger request comprises at least one of an identifier of the external server, the identifier of the terminal, an identifier of an application operated on the terminal, and a priority.

19. The method of claim 14, further comprising:

determining an overload state by managing at least one of a number of trigger requests transmitted from a specific external server and a total number of trigger requests transmitted from all external servers.

21. The method of claim 19, wherein the trigger request comprises information on a priority.

22. The method of claim 14, further comprising:

receiving a report on a success or a failure of the delivery of the short message from the short message server.
