The present invention discloses a method, system and device for processing circuit switched (CS) services in an evolved packet network. The method includes: receiving, by a mobility management entity, MME), a mobile terminated, MT, service indication from a mobile switching center, MSC; sending, by the MME, the MT service indication to a user equipment, UE; receiving, by the MME, an MT service response returned by the UE, wherein the MT service response carries a user choice result; and performing subsequent operations according to the MT service response. In the method of the present invention, when an MT service arrives, the MME does not trigger the evolved NodeB (eNodeB) to hand over the packet switched (PS) services of the UE but notifies the UE of the MT service and performs subsequent operations according to the MT service response returned by the UE, thus avoiding the waste of network resources caused by a meaningless handover of PS services.
