1. A method operable by a mobile entity in a wireless communication system, comprising:
- determining at least one of a location of the mobile entity, a movement of the mobile entity, or any combination thereof;
adjusting a timer between preferred system scans based on the at least one of the location of the mobile entity, the movement of the mobile entity, or any combination thereof, wherein the preferred system scans are terminated when a most preferred system is discovered;
caching previous systems the mobile entity has visited in a defined period prior to a current preferred system scan of the preferred system scans; and
avoiding at least one of a given frequency associated with at least one of the previous systems, a given cell associated with at least one of the previous systems, or any combination thereof during the current preferred system scan.

Abstract
Devices and methods are provided for optimizing the timing of multi-mode system scans in a wireless communication environment. In one embodiment, the method may involve determining at least one of location and movement of a mobile entity (ME). The method may involve adjusting a timer between preferred system scans based on the at least one of the location and the movement of the ME. For example, determining may involve utilizing a movement sensor (e.g., an accelerometer and/or a voltage-controlled oscillator accumulator) to detect the movement of the ME, and/or receiving signals from a Global Positioning System or the like.
