FIELD: radio engineering, communication.
SUBSTANCE: method for eliminating a failure includes the steps of receiving using the packet data network gateway P-GW, the downlink data after the failure detection in the associated first S-GW; and transmitting, via P-GW, a notification message to the MME mobility management node by using a second S-GW, wherein the notification message includes a P-GW identifier and a user identifier, so that when determining that the P-GW identifier contained in the notification message differs from the P-GW identifier corresponding to the context of the user identifier, MME rejects the initiation of the fault elimination procedure in the first S-GW.
EFFECT: providing the ability to prevent multiple fault elimination procedures and ease the burden on signalling.
