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

2-1. The method of claim 1, wherein the periodic access or location update related timer has one or more of:

a T3312 value for an RAU;

a T3312 extended value;

a T3412 value for a TAU; and

a T3412 extended value.

8. A method of providing information for MTC (Machine type communication) monitoring, the method performed by a network node and comprising:

receiving information regarding a monitoring related timer for any MTC device from an MTC related server;

acquiring information regarding a periodic access or location update related timer for the MTC device;

adjusting any one of the monitoring related timer and the periodic access or location update related timer on the basis of the other one;

performing monitoring on the basis of information regarding the adjusted timer; and

providing the information regarding the adjusted timer to the MTC device.

9. The method of claim 8, wherein the periodic access or location update related timer has one or more of:

a timer value for a periodic RAU (Routing Area Update);

a timer value for an RAU with a longer period;

a timer value for a periodic TAU (Tracking Area Update); and

a timer value for a TAU with a longer period.

10. The method of claim 8, wherein the periodic access or location update related timer has one or more of:

a T3312 value for an RAU;

a T3312 extended value;

a T3412 value for a TAU; and

a T3412 extended value.

11. The method of claim 8, wherein the adjusting additionally considers one or more of:

subscriber information;

capability information or priority information of the 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.

12. The method of claim 8, wherein in the adjusting, the periodic access or location update relater timer is adjusted on the basis of the monitoring related timer, or the monitoring related timer is adjusted on the basis of the periodic access or location update related timer.

13. The method of claim 8,

wherein the MTC related server is an MTC-IWF (Machine Type Communications-InterWorking Function), a service capability server, or an application server, or

wherein the node served for monitoring is an MME (Mobility Management Entity) or an SGSN (Serving GPRS Support Node).
