Abstract:
One embodiment of the present invention relates to a method by which a packet data network gateway (PGW) processes data for an UE in a wireless communication system, the method comprising the steps of: receiving a tracking area identifier (TAI) list from a mobility management entity (MME); and receiving downlink data for the UE from a network, wherein the PGW buffers the downlink data when all of the tracking areas (TAs), which belong to the TAI list, are not included in the same serving gateway (SGW) service region.
