Abstract

The present invention defines an efficient measurement method for idle mode M2M/MTC device with low/no mobility in a mobile communication system. An example of the mobile communication system to which the present invention is application is 3GPP UMTS mobile communication system and 3GPP LTE/LTE-A mobile communication system as the next generation mobile communication system under discussion in 3GPP.

Claims

1. A method by a terminal in a wireless communication system, the method comprising:

receiving, from a mobility management entity (MME), a first message including information on a timer associated with an idle mode;

starting the timer associated with the idle mode;

prohibiting operation of the idle mode including at least one of receiving a paging message and measuring a cell when the timer expires; and

resuming the operation of the idle mode when data to be transmitted is originated by the terminal.

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

3. The method of claim 1, wherein the terminal includes a machine to machine (M2M) device or a machine type communication (MTC) device.

4. The method of claim 1, wherein the first message includes at least one of an attach request accept message, a tracking area update accept message or a routing area update accept message.

5. The method of claim 1, the method further comprising:

performing the operation of the idle mode before the timer expires.

6. A terminal in a wireless communication system, the terminal comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

receive, from a mobility management entity (MME), a first message including information on a timer associated with an idle mode,

start the timer associated with the idle mode,

prohibit operation of the idle mode including at least one of receiving a paging message and measuring a cell when the timer expires, and

resume the operation of the idle mode when data to be transmitted is originated by the terminal.

7. The terminal of claim 6, wherein the first message is a non access stratum (NAS) message.

8. The terminal of claim 6, wherein the terminal includes a machine to machine (M2M) device or a machine type communication (MTC) device.

9. The terminal of claim 6, wherein the first message includes at least one of an attach request accept message, a tracking area update accept message or a routing area update accept message.

10. The terminal of claim 6, wherein the controller is further configured to perform the operation of the idle mode before the timer expires.

11. A method by a mobility management entity (MME) in a wireless communication system, the method comprising:

receiving a first message from a terminal; and

transmitting, to the terminal, a second message including information on a timer associated with an idle mode,

wherein the timer is started by the terminal,

wherein the timer is used for prohibiting operation of the idle mode including at least one of receiving a paging message and measuring a cell when the timer expires, and

wherein the operation of the idle mode is resumed by the terminal when data to be transmitted is originated by the terminal.

12. The method of claim 11, wherein the first message and the second message are a non access stratum (NAS) message.

13. The method of claim 11, wherein the terminal includes a machine to machine (M2M) device or a machine type communication (MTC) device.

14. The method of claim 11, wherein the second message includes at least one of an attach request accept message, a tracking area update accept message or a routing area update accept message.

15. The method of claim 11,

wherein the timer is used for performing the operation of the idle mode before the timer expires by the terminal.

16. A mobility management entity (MME) in a wireless communication system, the MME comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

receive a first message from a terminal, and

transmit, to the terminal, a second message including information on a timer associated with an idle mode,

wherein the timer is started by the terminal,

wherein the timer is used for prohibiting operation of the idle mode including at least one of receiving a paging message and measuring a cell when the timer expires, and

wherein the operation of the idle mode is resumed by the terminal when data to be transmitted is originated by the terminal.

17. The MME of claim 16, wherein the first message and the second message are a non access stratum (NAS) message.

18. The MME of claim 16, wherein the terminal includes a machine to machine (M2M) device or a machine type communication (MTC) device.

19. The MME of claim 16, wherein the second message includes at least one of an attach request accept message, a tracking area update accept message or a routing area update accept message.

20. The MME of claim 16,

wherein the timer is used for performing the operation of the idle mode before the timer expires by the terminal.
