A method for dealing with the packet domain gateway support node errors, including: a Radio Network Controller (4) sends a notification message to a Serving GPRS Support Node (2) according to an error indication message; in the case of a direct tunnel, the Serving GPRS Support Node initiates a process of deactivating a packet data protocol context to a user equipment (1) according to the received notification message, so as to make the states of the packet data protocol contexts in the user equipment, the Serving GPRS Support Node and a Gateway GPRS Support Node (3) consistent. Applying the method of the present invention, an RNC sends a notification to an SGSN after receiving the error indication message from GGSN. If the SGSN determines that the bearer is of direct tunnel and the GGSN is abnormal according to the received abnormality notification, it initiates a process of deactivating a PDP context to a UE so as to avoid the PDP contexts in the SGSN and the UE being hung up for a long time, and to ensure the consistency of the PDP contexts in the UE, SGSN and GGSN.
