Abstract

The invention provides a business disaster tolerance method and a related device, and the problems of poor disaster tolerance effect of the prior art can be solved. The method is characterized in that the MME is used to transmit the request information to the DNS server, and comprises the MME pool area identification of the MME; the MME is used to receive the request response information transmitted by the DNS server, and comprises the MMEC of the MME pool area; the MME is used to determine the backup MME according to the MMEC of the MME pool area; the MME is used to transmit the interface request information to the DNS server, and comprises the MMEC of the backup MME and the pool area identification of the MME pool area; the MME is used to receive the interface response information transmitted by the DNS server, and comprises the interface information of the backup MME; the MME is used to transmit the user information of the UE attached to the MME according to the interface information of the backup MME. The method is suitable for the communication technology.

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 that multiple MMEs serve the same wireless area at the same time, and each MME in the MME Pool is interconnected with all base stations in the MME Pool , MMEs in the MMEPool implement resource sharing and service load sharing. [0003] When an MME in the MMEPool 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 the preset strategy, such as the principle of load balancing , send the service request of the UE to another MME that works normally in the MMEPool, the MME that works normally will reject the service request of the UE, and the UE needs to restore the...
