A mobile communication method is discussed involving causing Mobile Switching Center (MSC) server/Circuit Switch-Media Gateway (CS-MGW) to transmit a path switching signal and activate a timer, causing User Equipment (UE) #2 to switch a transmission destination of a voice communication data signal addressed to UE#1 from Serving/Packet Data Network Gateway (S/P-GW) to the MSC server/CS-MGW, causing the MSC server/CS-MGW transmits a path restoration instruction signal if not detecting that handover of the UE#1 from Evolved Universal Terrestrial Radio Access Network (E-UTRAN) to UTRAN/GSM and EDGE Radio Access Network (GERAN) is completed before the timer expires, and causing the UE#2 to switch a transmission destination of the voice communication data signal addressed to the UE#1 from the MSC server/CS-MGW to the S/P-GW in response to the path restoration instruction signal.
