The embodiment of the invention discloses a method for reducing the circuit domain, a network device and a system. The method comprises: a network device determines service cell switching user equipment UE end, network equipment determined before the service cell switching process of the UE end of the UE has identified the need to move to the second network, among them, the second network to support the circuit domain service network, the UE mobile network equipment to the second network. By the above method, the conflict service cell switching process when UE launched CS business triggered CSFB and UE, the network equipment can be in the service cell switching process end UE, UE will move to support the CS service in the network, so that the CS business UE can continue to improve the establishment of the CS business success rate. The invention also discloses a network device and system for the circuit domain falling down.
