Abstract: A communications method includes receiving, by user equipment (UE), a first message from a network side, where the first message is used to indicate to the UE to perform circuit switched fallback (CSFB) as a called party, where the first message includes first information, and where the first information is used to indicate an incoming call number. If it is determined that a preset condition is met, the communications method further includes sending a second message to the network side, where the second message is used to indicate that the CSFB is rejected, and where the preset condition includes at least one of the incoming call number is restricted or the UE is in a mode of automatically rejecting a CSFB incoming call.
