摘要:
Embodiments of the present invention provide a failure handling method, a packet data network, a mobility management entity, and a network system. The failure handling method provided in the embodiments of the present invention includes: receiving, by a packet data network gateway P-GW, downlink data after detecting that a failure occurs in an associated first S-GW; and sending, by the P-GW, a notification message to a mobility management entity MME by using a second S-GW, where the notification message includes an identifier of the P-GW and an identifier of a user, so that when determining that the identifier of the P-GW included in the notification message is different from a P-GW identifier corresponding to a context identifier of the user, the MME refuses to initiate a procedure for recovering from the failure in the first S-GW. The embodiments of the present invention can prevent a failure recovery procedure from being executed multiple times, and lighten signaling load.
