Beschreibung
Zusammenfassung:	The invention discloses a mobility management entity, and a disaster tolerant method and a disaster tolerant system thereof, relating to the field of wireless communication. In the embodiment provided by the invention, a current serving MME synchronizes disaster tolerant data of a user to an HSS; when the current serving MME fails, a takeover MME obtains the disaster tolerant data of the user from the HSS; therefore, a calling service and a called service of the user are recovered in real time; the services can be recovered without waiting the user to be re-attached to the takeover MME; and thus, the reliability of a LTE network and the service quality are increased.
