Abstract
An architecture is described that can determine a scanning schedule for reselection scanning in connection with a wireless communication network or service. The architecture can monitor various indicia relating to recent movement of user equipment (UE) such as a wireless device, and, based upon such recent movement indicia, construct a mobility pattern for the UE. In addition, based upon the mobility pattern, the architecture can generate a reselection scanning schedule for the UE designed to optimize tradeoffs between battery life and network awareness.
