Abstract

An embodiment of the invention provides a gateway equipment disaster tolerance method and communication equipment. The gateway equipment disaster tolerance method comprises the steps that: first access and mobile management equipment receives a business request of terminal equipment; the first access and mobile management equipment responds to the service request, determines that the first gatewaycontrol plane equipment fails, and selects a second gateway control plane equipment, wherein the first gateway control plane equipment is used for managing the session of the terminal equipment in the gateway user plane equipment; and the first access and mobility management equipment sends a first message to the second gateway control plane equipment, wherein the first message comprises first disaster recovery data corresponding to the terminal equipment, and the first disaster recovery data is used for the second gateway control plane equipment to recover a session of the terminal equipmentin the gateway user plane equipment according to the first disaster recovery data. By adopting the gateway equipment disaster tolerance method and the communication equipment of the invention, the complexity of session recovery can be simplified, the reliability of session recovery is improved, the resource utilization rate is improved, and the cost is reduced.
