Abstract

Embodiments of the present invention solve the problem in the prior art of poor service disaster recovery effects. Provided are a service disaster recovery method, a related device, and a communication system. The method comprises: when a mobile management entity (MME) attached to a user equipment (UE) malfunctions, a serving MME receives a query request message transmitted by a network element, where the query request message is used for requesting the MME attached to the UE for acquiring information corresponding to a service of the UE, the query request message comprises an identity of the MME attached to the UE and an identity of the UE, and the MME attached to the UE and the serving MME are located in a same MME pool area; the serving MME acquires user information of the UE on the basis of the identity of the UE; and, the serving MME determines the information corresponding to the service of the UE on the basis of the user information of the UE and transmits a query response message to the network element, where the query response message comprises the information corresponding to the service of the UE. The method is applicable in the field of communication technologies.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a service disaster recovery method, a related device and a communication system. Background technique [0002] Under the Long Term Evolution (LTE) network architecture, the Mobility Management Entity (MME) pool area (Pool) is a plurality of MMEs serving the same wireless area at the same time, and each MME in the MME Pool and the MME Pool All base stations in the MME Pool are interconnected, and the MMEs in the MME Pool realize resource sharing and service load sharing. [0003] However, the existing service disaster recovery method is ineffective. For example, when the UE is attached to the current MME to perform the called service based on LTE-based voice (Voice over LTE, VoLTE), if the current MME fails, due to the current The MME cannot handle the work related to the UE's VoLTE called service, which causes the UE's VoLTE called service to fail this time.
