Abstract

A method for adjusting a timer value for a device includes determining, by a home subscribing server (HSS), a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum time period, wherein the timer value for the RAU or the TAU is determined to be 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 determined timer value for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

Claims

1. A method for adjusting a timer value for a user equipment (UE), the method comprising:

determining, by a home subscribing server (HSS), a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum detection time period of loss of connectivity,

wherein the timer value for the RAU or the TAU is determined to be a smaller value than the maximum detection time period of the loss of connectivity,

wherein the loss of connectivity is related to signaling between the UE and a network, and

wherein the maximum detection time period of the loss of connectivity is used for detecting that the UE is no longer reachable for signaling to the network; and

transmitting, by the HSS, information including the determined timer value 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 detection time period of the loss of connectivity is for transmitting an event to an application server (AS).

4. The method of claim 1, wherein the timer value for the RAU or the TAU is set based on 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 maximum detection time period of the loss of connectivity is received from an application server (AS), and

wherein the AS is a Machine Type Communication-InterWorking Function (MTC-IWF) or a service capability server.

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

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

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

9. A home subscription server (HSS) for adjusting a timer value for a user equipment (UE), the HSS comprising:

a processor configured to determine a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum detection time period of the loss of connectivity,

wherein the timer value for the RAU or the TAU is determined to be a smaller value than the maximum detection time period of the loss of connectivity,

wherein the loss of connectivity is related to signaling between the UE and a network, and

wherein the maximum detection time period of the loss of connectivity is used for detecting that the UE is no longer reachable for signaling to the network; and

a transceiver configured to transmit information including the determined timer value for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

10. The HSS of claim 9, 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.

11. The HSS of claim 9, wherein the maximum detection time period of the loss of connectivity is for transmitting an event to an application server (AS).

12. The HSS of claim 9, wherein the timer value for the RAU or the TAU is set based on 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.

13. The HSS of claim 9, wherein the maximum detection time period of the loss of connectivity is received from an application server (AS), and

wherein the AS is a Machine Type Communication-InterWorking Function (MTC-IWF) or a service capability server.

14. The HSS of claim 9, wherein the HSS stores an identifier (ID) of a Machine Type Communication (MTC) server.

15. The HSS of claim 9, wherein the UE is a Machine Type Communication (MTC) device.

16. The HSS of claim 9, wherein after the maximum detection time period of the loss of connectivity lapses, the loss of the connectivity is identified.
