A handover processing method in a Media Gateways (MGW) in which a Mobile Switching Center (MSC) server can perform a handover operation regardless of a switch type of the MGW by allowing a MGW only supporting a single-switch to provide the same handover processing as one supporting a multi-switch, the handover processing method comprising: the MGW receiving a termination setup message from the MSC server when one terminal (UE) performs handover to a new RNC area; generating a new termination according to the termination setup message, and checking topology information indicating a direction between two terminations; and connecting a switch between the two terminations only when the direction indicated in the topology information is set as a both-way.
