## 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.
