Problems solved by technology

In this way, the backup gateway control plane device does not participate in business processing, the resource utilization rate is low, and a centralized control node is required for fault monitoring and control switching operations, which is costly
Moreover, after the active control plane device fails, a large number of sessions need to be restored, the recovery process is complicated, and there is a risk of session recovery failure on the standby control plane device

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.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a gateway device disaster recovery method and a communication device. Background technique [0002] In the prior art, based on the concept of separating the control plane and the user plane, the network architecture includes gateway control plane equipment and gateway user plane equipment. The gateway control plane equipment is usually used as a session management functional The device selects the gateway user plane device. After the gateway control plane device selects the gateway user plane device for the terminal device, the gateway control plane device manages the session of the terminal device on the gateway user plane device, such as traffic monitoring, billing and so on. [0003] In order to ensure that the system can still maintain the session when the gateway control plane device fails, at present, the gateway control plane device usually adopts the active...
