ABSTRACT:
In one aspect, the invention provides a method for tracking a mobile terminal. In some embodiments, this method includes the following steps: receiving a signal transmitted from the mobile terminal; searching a primary search area for a signal associated with the mobile terminal; searching a secondary search area for a signal associated with the mobile terminal, wherein the secondary search area is larger than the primary search area; determining the strength of a signal associated with the mobile terminal that was found by searching the secondary search area; and determining whether the primary search area should be modified based on the determined strength of the signal that was found by searching the secondary search area.
