Abstract

Embodiments of the present invention provide a service disaster recovery method and a related device, which solve the problem of poor service disaster recovery effect in the prior art. The method includes: the MME sends a request message to the DNS server, including the pool area identifier of the MME pool area where the MME is located; the MME receives the request response message sent by the DNS server, including the MMECs of all MMEs in the MME pool area; the MME according to the MME pool area The MMEC of all MMEs in the MME determines the backup MME of the MME; the MME sends an interface request message to the DNS server, including the MMEC of the backup MME and the pool area identifier of the MME pool area; the MME receives the interface response message sent by the DNS server, including the interface of the backup MME information; the MME sends the user information of the UE attached to the MME to the backup MME according to the interface information of the backup MME. The method is applicable to the technical field of communication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and a related device for service disaster recovery. 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] When an MME in the MME Pool fails, if the user equipment (User Equipment, UE) attached to the faulty MME actively initiates a service request, the base station serving the UE will pass a preset policy, such as load balancing In principle, the service request of the UE is sent to another normal working MME in the MME Pool, the normal working MME will reject the service request of the UE, and the UE needs to rea...
