Abstract

A method and apparatus for triggering at least one machine type communications (MTC) application using at least one wireless transmit/receive unit (WTRU) is disclosed. The method includes receiving a triggering message including a device trigger (DT) and a maximum delayed response time value from a core network entity (CN), storing the DT in the WTRU, initiating a timer in the WTRU set to the maximum delayed response time value, and on a condition that the timer expires, the WTRU transitioning to a radio resource control (RRC) connected mode and dispatching the DT to the MTC application.

Claims

1. A method for triggering at least one machine type communications (MTC) application using at least one wireless transmit/receive unit (WTRU), the method comprising:

receiving a triggering message including a device trigger (DT) and a maximum delayed response time value from a core network entity (CN);

storing the DT in the WTRU;

initiating a timer in the WTRU set to the maximum delayed response time value; and

on a condition that the timer expires, the WTRU transitioning to a radio resource control (RRC) connected mode and dispatching the DT to the MTC application.

2. The method as in claim 1, wherein the CN entity is a mobility management entity (MME).

3. The method as in claim 1, wherein the CN entity is a serving general packet radio service (GPRS) support node (SGSN).

4. The method as in claim 1, wherein the CN entity is a mobile switching center (MSC).

5. The method as in claim 1, wherein the triggering message is received in a cell broadcast.

6. The method as in claim 1, wherein the triggering message is received in a non-access stratum (NAS) message.

7. A method for triggering at least one machine type communications (MTC) application using at least one wireless transmit/receive unit (WTRU), the method comprising:

receiving a triggering message including a device trigger (DT) and a maximum delay value from a core network (CN) entity;

the WTRU dispatching the DT to the MTC application;

receiving, at the WTRU, a trigger response message from the MTC application;

storing the trigger response message in the WTRU;

initiating a timer in the WTRU set to the maximum delay value; and

on a condition that the timer expires, the WTRU transitioning to a radio resource control (RRC) connected mode and forwarding the trigger response message to an MTC server.

8. The method as in claim 7, wherein the CN entity is a mobility management entity (MME).

9. The method as in claim 7, wherein the CN entity is a serving general packet radio service (GPRS) support node (SGSN).

10. The method as in claim 7, wherein the CN entity is a mobile switching center (MSC).

11. The method as in claim 7, wherein the triggering message is received in a cell broadcast.

12. The method as in clam 7, wherein the triggering message is received in a non-access stratum (NAS) message.

13. A method for triggering at least one machine type communications (MTC) application using a control) in a core network (CN) entity, the method comprising:

receiving an MTC device trigger request from an MTC-interworking function (IWF);

transmitting an acknowledgment that the MTC device trigger request is being processed;

determining if the MTC device trigger request includes a preference of point-to-point delivery; and

transmitting the MTC device triggering request to a wireless transmit/receive unit (WTRU) using point-to-point delivery.

14. The method as in claim 13, wherein the CN is a mobility management entity (MME).

15. The method as in claim 13, wherein the CN entity is a serving general packet radio service (GPRS) support node (SGSN).

16. The method as in claim 13, wherein the CN entity is a mobile switching center (MSC).

17. The method as in claim 13, wherein the MTC device triggering request message is received in a cell broadcast.

18. The method as in claim 13, wherein the MTC device triggering request message is received a non-access stratum (NAS) message.

19. A wireless transmit/receive unit (WTRU) for triggering at least one machine type communications (MTC) application, the WTRU comprising:

a receiver configured to receive a triggering message including a device trigger (DT) and a maximum delayed response time value from a core network entity (CN);

a processor configured to store the DT;

the processor further configured to initiate a timer set to the maximum delayed response time value; and

on a condition that the timer expires, the processor is further configured to transition to a radio resource control (RRC) connected mode and a transmitter configured to dispatch the DT to the MTC application.
