Abstract
The invention introduces a method and an apparatus for fast recovery. The fast recovery method comprises: evaluating data download qualities of non-current RATs (Radio Access Technologies) to obtain a candidate RAT list; determining whether a PS (Packet Service) download quality of a current RAT becomes worse; and if the PS download quality of the current RAT becomes worse, selecting one RAT from the candidate RAT list and switching to the selected RAT. The method and the apparatus for fast recovery introduced by the invention realize the seamless RAT switch and maintain the continuous data transmission.
