A method for gateway recovery processing and device, the method comprising: in the case where a terminal moves from a first mobility management unit to a second mobility management unit, the second mobility management unit receiving flag information from the first mobility management unit, wherein the flag information being used to indicate that a connection signaling of a packet data network (PDN) is in a suspension state; and the second mobility management unit transmitting the flag information to a serving gateway (SGW), the flag information being used to trigger the SGW to send a bearing update request message to a PGW as a packet data network element. The above technical solution achieves that the PGW is notified when a UE moves to a new mobility management unit, so as to ensure the terminal to receive downlink service.
