Methods, systems, and devices are described for defining a tracking area for a mobile device. The mobile device may determine that it is traveling along an identified route. The mobile device may send an indication to a core cellular network that it is traveling along the identified route and, therefore, refrain from sending tracking area update messages as it enters new tracking areas along the route. The core cellular network may receive the message and define a tracking area for the mobile device based on the information associated with the identified route. The core cellular network may define the tracking area and send page(s) to the mobile device without receiving tracking area update reporting messages from the mobile device as it travels along the identified route.
