The present invention discloses a method for switching a standby mode, including: when user equipment UE camps on a first network, sending, by the UE to a network device, a single-domain registration request needed when the network device performs mobility management on the UE, where the single-domain registration request carries a first information element IE, and the first IE identifies that the UE has a circuit-switched CS domain voice capability, where the UE is a single card dual standby terminal, the UE is currently in a standby state in both the first network and a second network, the first network supports a packet switched PS domain service, and the second network supports a CS domain service; and if the UE receives a second IE fed back according to the single-domain registration request by the network device, exiting, by the UE, the standby state in the second network, where the second IE identifies that the first network supports circuit switched fallback CSFB. Moreover, the present invention discloses user equipment UE and a network device. |
