A method for managing wireless assets in a first coverage area based upon call activity in at least one second coverage area substantially adjacent with the first coverage area includes the steps of: (a) in no particular order: (1) selecting a parameter relating to the call activity; and (2) selecting at least one threshold value for the parameter relating to imminence of increased call activity in the first coverage area; (b) measuring the parameter in at least one region in the at least one second coverage area; and (c) when the parameter substantially meets the at least one threshold value, reserving a measure of call-handling capacity from call activity in the first coverage area for use in said at least one second coverage area.
