Abstract

Techniques are described that can be used for efficient mobility management signaling. In some cases, a network can specify an extended timer used for a machine to machine (M2M) type device to communicate with a network. The extended timer can be transmitted in connection with an attachment acceptance message, Location Updating Accept message, Tracking Area Update Accept, or Routing Area Update Accept message. In some cases, a timer can be adjusted using a multiplier in order to increase a period at which communications with the network occur. The network can transmit an indication to change a timer by multiplying the timer with the multiplier.

Claims

1. An apparatus comprising:

a physical layer interface to provide physical layer processing of messages to be transmitted or received over a wireless network; and

a processor coupled with the physical layer interface to;

generate a routing area update request or an attach request to include an indicator to cause a network to provide the apparatus with an extended timer value, the routing area update request or attach request to be transmitted by the physical layer interface;

identify the extended timer value from an accept message received in response to the routing area update request or attach request;

determine a value of a timer based on the extended timer value; and

perform a routing area update procedure or an attach procedure based on the value of the timer,

wherein the timer is a T3312 timer or a T3412 timer and the accept message includes the extended timer value in an octet with bits 1-5 of the octet to represent a binary-coded timer value and bits 6-8 of the octet to define a unit of the extended timer value, wherein the unit is an increment greater than 10 hours.

2. The apparatus of claim 1, wherein the accept message is a routing area update accept message and the processor is to generate the routing area update request to include the indicator and perform the routing area update procedure based on the value of the timer.

3. The apparatus of claim 1, wherein the accept message is an attach accept message and the processor is to generate the attach request to include the indicator and perform the attach procedure based on the value of the timer.

4. The apparatus of claim 1, wherein the extended timer value is a first extended timer value and the processor is further to:

determine the value of the timer based on the first extended timer value instead of a second extended timer value received in a broadcast transmission.

5. A user equipment (UE) comprising:

means to transmit, in a routing area update request or an attach request, an indicator to cause a network to provide the UE with an extended timer value;

means to receive, in an accept message, the extended timer value;

means to determine a value of a timer based on the extended timer value; and

means to perform a routing area update procedure or an attach procedure based on the value of the timer,

wherein the timer is a T3312 timer or a T3412 timer and the accept message includes the extended timer value in an octet with bits 1-5 of the octet to represent a binary-coded timer value and bits 6-8 of the octet to define a unit of the extended timer value, wherein the unit is an increment greater than 10 hours.

6. The UE of claim 5, wherein the accept message is a routing area update accept message and the UE is to transmit the indicator in the routing area update request and perform the routing area update procedure based on the value of the timer.

7. The UE of claim 5, wherein the accept message is an attach accept message and the UE is to transmit the indicator in the attach request and perform the attach procedure based on the value of the timer.

8. The UE of claim 5, wherein the extended timer value is a first extended timer value and the means to determine the value of the timer is further to:

determine the value of the timer based on the first extended timer value instead of a second extended timer value received in a broadcast transmission.

9. An apparatus comprising:

means to receive, in a routing area update request or an attach request transmitted by a user equipment (UE), an indicator; and

means to transmit, in an accept message, an extended timer value based on the indicator, wherein the extended timer value is to be used to determine a value of a timer for a performance of a routing area update procedure or an attach procedure,

wherein the timer is a T3312 timer or a T3412 timer and the accept message includes the extended timer value in an octet with bits 1-5 of the octet to represent a binary-coded timer value and bits 6-8 of the octet to define a unit of the extended timer value, wherein the unit is an increment greater than 10 hours.

10. The apparatus of claim 9, wherein the accept message is a routing area update accept message and the apparatus is to receive the indicator in the routing area update request.

11. The apparatus of claim 9, wherein the accept message is an attach accept message and the apparatus is to receive the indicator in the attach request.

12. An apparatus comprising:

a physical layer interface to process a message that includes a routing area update request or an attach request transmitted by a user equipment (UE); and

processing circuitry coupled with the physical layer interface, to;

identify an indicator in the routing area update request or attach request; and

generate an accept message to include an extended timer value based on the indicator,

wherein the extended timer value is to be used to determine a value of a timer for a performance of a routing area update procedure or an attach procedure and the physical layer interface is to cause transmission of the accept message,

wherein the timer is a T3312 timer or a T3412 timer and the accept message includes the extended timer value in an octet with bits 1-5 of the octet to represent a binary-coded timer value and bits 6-8 of the octet to define a unit of the extended timer value, wherein the unit is an increment greater than 10 hours.

13. The apparatus of claim 12, wherein the accept message is routing area update accept message and the apparatus is to receive the indicator in the routing area update request.

14. The apparatus of claim 12, wherein the accept message is an attach accept message and the apparatus is to receive the indicator in the attach request.

15. The apparatus of claim 12, wherein the extended timer value is a first extended timer value and the processing circuitry is further to:

cause a second extended timer value to be transmitted in a broadcast transmission.
