1. An MME (Mobility Management Entity) used in a mobile communication system comprising:
a receiver configured to receive a message related to paging from an MSC/VLR (Mobile Switching Center/Visitor Location Register) over a SGs interface between the MME and the MSC/VLR; and
a processor configured to discard the message, if handover procedure from an LTE (Long Term Evolution) wireless area to a 3G or a 2G wireless area is ongoing when the MME receives the message,
wherein no further action for the paging is performed by the MME after the MME discards the message.
