Abstract
A method for voice call fallback to a circuit switched (CS) domain disclosed in the present invention includes: receiving a Service Request message from a calling user equipment (UE) where the Service Request message includes called number information of a voice call in a CS domain instructing an evolved NodeB (eNB) to initiate circuit switched fallback (CSFB) handover; receiving a Handover Request message from the eNB where the Handover Request message includes information required for CS handover selecting a mobile switching center (MSC) and sending a packet switched (PS) to CS Handover Request message to the MSC where the PS to CS Handover Request message carries information required for the CS handover and a called number so that the MSC calls a called UE. The corresponding apparatuses and systems are also disclosed. The technical solution of the present invention can reduce the connection delay.
