Abstract

The present disclosure presents a method of providing information by a subscriber information server for machine type communication (MTC) monitoring. The method may include: receiving information on a monitoring related timer for any MTC device from an MTC related server; adjusting one of the monitoring related timer and a periodic access or location update related timer based on the other timer when there is information on the periodic access or location update related timer for the MTC device; and transmitting information on the adjusted timer to the MTC related server or a monitoring node.

Claims

1. A method for adjusting a timer value for a device, the method comprising:

receiving, by a home subscribing server (HSS) from an application server (AS), information on a maximum time period;

setting, by the HSS, a timer value for a routing area update (RAU) or a tracking area update (TAU) to a smaller value than the maximum time period,

wherein the maximum time period is related to a loss of a connectivity indicating the device is no longer possible to be signaled; and

delivering, by the HSS, information regarding the timer value set for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

2. The method of claim 1, wherein the timer value for the RAU or the TAU includes one or more of:

a T3312 value for the RAU;

a T3312 extended value for the RAU;

a T3412 value for the TAU; and

a T3412 extended value for the TAU.

3. The method of claim 1, wherein the maximum time period is for transmitting an event to the AS.

4. The method of claim 1, wherein the setting of the timer value for the RAU or the TAU includes considering one or more of:

subscriber information;

capability information or priority information of a Machine Type Communication (MTC) device;

operator policy information;

MTC monitoring related information;

information acquired from another node;

network status information;

information associated with a mobility management related operation; and

information association with a session management related operation.

5. The method of claim 1, wherein the AS is a Machine Type Communication-InterWorking Function (MTC-IFW) or a service capability server.

11. The method of claim 1, wherein the HSS stores a Machine Type Communication (MTC) server identifier (ID).

12. The method of claim 1, wherein the device is a Machine Type Communication (MTC) device.

15. The method of claim 1, wherein after the maximum time period lapses, the loss of the connectivity is identified.

6. A home subscription server (HSS) for adjusting a timer value for a device, the HSS comprising:

a transceiver configured to receive, from an application server (AS), information on a maximum time period; and

a processor configured to set a timer value for a routing area update (RAU) or a tracking area update (TAU) to a smaller value than the maximum time period,

wherein the maximum time period is related to a loss of a connectivity indicating the device is no longer possible to be signaled, and

wherein the transceiver delivers information regarding the timer value set for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

7. The HSS of claim 6, wherein the timer value for the RAU or the TAU includes one or more of:

a T3312 value for the RAU;

a T3312 extended value for the RAU;

a T3412 value for the TAU; and

a T3412 extended value for the TAU.

8. The HSS of claim 6, wherein the maximum time period is for transmitting an event to the AS.

9. The HSS of claim 6, wherein the processor sets the timer value for the RAU or the TAU by considering one or more of:

subscriber information;

capability information or priority information of a Machine Type Communication (MTC) device;

operator policy information;

MTC monitoring related information;

information acquired from another node;

network status information;

information associated with a mobility management related operation; and

information association with a session management related operation.

10. The HSS of claim 6, wherein the AS is a Machine Type Communication-InterWorking Function (MTC-IFW) or a service capability server.

13. The HSS of claim 6, wherein the HSS stores a Machine Type Communication (MTC) server identifier (ID) for a reporting destination of a monitoring event.

14. The HSS of claim 6, wherein the device is a Machine Type Communication (MTC) device.

16. The HSS of claim 6, wherein after the maximum time period lapses, the loss of the connectivity is identified.
