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 location update request to include an indicator to cause a network to provide the apparatus with an extended timer value for a location area update procedure, the location update request to be transmitted by the physical layer interface;

identify the extended timer value from a location update accept message;

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

perform the location area update procedure based on the value of the timer,

wherein the timer is a T3212 timer and the extended timer value is;

a T3212 multiplier or an extended T3212 timer value;

transmitted in an octet, where bits 1-5 of the octet represent a binary-coded timer value and bits 6-8 of the octet define a unit of the extended timer value, the unit being an increment greater than 10 hours.

2. The apparatus of claim 1, wherein the extended timer value is transmitted as part of a control channel descriptor information element.

3. A user equipment (UE) comprising:

means to transmit, in a location update request, an indicator to cause a network to provide the UE with an extended timer value for a location area update procedure;

means to receive, in a location update accept message, the extended timer value, wherein the extended timer value is a T3212 multiplier or an extended T3212 timer value; and

is transmitted in an octet, where bits 1-5 of the octet represent a binary-coded timer value and bits 6-8 of the octet define a unit of the extended timer value, the unit being an increment greater than 10 hours;

means to determine a value of a T3212 timer based on the extended timer value; and

means to perform the location area update procedure based on the value of the T3212 timer.

4. An apparatus comprising:

means to receive, in a location update request transmitted by a user equipment (UE), an indicator for a location area update procedure; and

means to transmit, in a location update 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 T3212 timer for the performance of the location area update procedure;

is a T3212 multiplier or an extended T3212 timer value; and

is transmitted in an octet, where bits 1-5 of the octet represent a binary-coded timer value and bits 6-8 of the octet define a unit of the extended timer value, the unit being an increment greater than 10 hours.

5. The apparatus of claim 4, wherein the extended timer value is transmitted in the location update accept message as part of a control channel descriptor information element.

6. An apparatus comprising:

a physical layer interface to process a location update request message from a user equipment (UE);

processing circuitry coupled with the physical layer interface, to;

identify an indicator in the location update request message; and

generate a location update 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 T3212 timer for performance of a location area update procedure;

is a T3212 multiplier or an extended T3212 timer value; and

is transmitted in an octet, where bits 1-5 of the octet represent a binary-coded timer value and bits 6-8 of the octet define a unit of the extended timer value, the unit being an increment greater than 10 hours; and

the physical layer interface is to cause transmission of the location update accept message.

7. The apparatus of claim 6, wherein the extended timer value is transmitted in the location update accept message as part of a control channel descriptor information element.
