Abstract

A method and apparatus for triggering a machine type communication (MTC) wireless transmit/receive unit (WTRU) is disclosed. An MTC WTRU receives a message that indicates control period configuration information associated with an extended discontinuous reception (DRX) cycle. The MTC WTRU monitors a paging channel during a control period. The MTC WTRU connects, in response to receiving a paging message during the control period, to an MTC server and transmits data to the MTC server.

Claims

1. A method of paging a machine type communication (MTC) wireless transmit/receive unit (WTRU), the method comprising:

receiving, by the MTC WTRU, a message that indicates control period configuration information associated with an extended discontinuous reception (DRX) cycle and reporting period configuration information;

monitoring, by the MTC WTRU, a paging channel during a control period;

receiving, by the MTC WTRU, a paging message during the control period;

attaching to a network, by the MTC WTRU, in response to receiving the paging message;

receiving, by the MTC WTRU, a trigger message; and

in response to receiving the trigger message, the MTC WTRU connecting to an MTC server and transmitting data to the MTC server, during a reporting period.

2. The method of claim 1, wherein the message is received from a mobility management entity (MME).

3. The method of claim 2, wherein the MME is aware of the control period and extended DRX cycle of the MTC WTRU.

4. The method of claim 1, wherein the message is a non-access stratum (NAS) message.

5. The method of claim 1, wherein the MTC server is aware of the control period and extended DRX cycle of the MTC WTRU.

6. The method of claim 1 further comprising the MTC WTRU entering an idle/offline mode after transmitting data to the MTC server or after the control period.

7. The method of claim 1, wherein the MTC WTRU connects to the MTC server via a packet data network (PDN) connection.

8. The method of claim 1, wherein a mobility management entity (MME) sends the paging message to the MTC WTRU upon a request from the MTC server.

9. The method of claim 8, wherein the request is sent from the MTC server to the MME via a device trigger gateway.

10. The method of claim 1, further comprising transmitting, by the MTC WTRU, extended DRX information.

11. The method of claim 10, wherein the extended DRX information is transmitted in at least one of a tracking/routing area update message or an attach/detach request message.

12. The method of claim 1, further comprising receiving, by the MTC WTRU, a message that includes updated control period configuration information.

13. The method of claim 12, wherein the updated control period configuration information is received in at least one of an attach accept/reject, detach accept/reject, or tracking area update/routing area update accept/reject message.

14. The method of claim 12, wherein the updated control period configuration information is received from at least one of a serving general packet radio service support node (SGSN), a mobility management entity (MME), or the MTC server.

15. A machine type communication (MTC) wireless transmit/receive unit (WTRU) comprising:

circuitry configured to receive a message that indicates control period configuration information associated with an extended discontinuous reception (DRX) cycle and reporting period configuration information;

circuitry configured to monitor a paging channel during a control period;

circuitry configured to receive a paging message during the control period;

circuitry configured to attach to a network in response to receiving the paging message;

circuitry configured to receive a trigger message; and

circuitry configured to connect, in response to receiving the trigger message to an MTC server and to transmit data to the MTC server, during a reporting period.

16. The MTC WTRU of claim 15, wherein the message is received from a mobility management entity (MME).

17. The MTC WTRU of claim 16, wherein the MME is aware of the control period and extended DRX cycle of the MTC WTRU.

18. The MTC WTRU of claim 15, wherein the message is a non-access stratum (NAS) message.

19. The MTC WTRU of claim 15, wherein the MTC server is aware of the control period and extended DRX cycle of the MTC WTRU.

20. The MTC WTRU of claim 15 wherein the MTC WTRU is configured to enter an idle/offline mode after the MTC WTRU transmits data to the MTC server or after the control period.
