A method and device for hss active/standby management

Abstract

The invention discloses a method for HSS active and standby management, which is used to ensure the reliability and stability of HSS equipment. The method is as follows: in the system configuration phase, a disk of the same size is created on the HSS master node and the HSS standby node to synchronize the distributed replication block device DRBD to form a disk mirror area; in the system operation phase, mount the mount point of the disk mirror area to Loaded on the HSS master node, the data generated by the HSS master node is backed up in the disk mirror area in real time, and the running status of the HSS master node is monitored in real time, and when the running status of the HSS master node is determined to be abnormal, the service will be switched to HSS The standby node and mount the mount point of the disk mirror area on the HSS standby node. This not only ensures that the HSS primary node can be switched to the HSS standby node in time when a failure occurs, but also ensures that data can be synchronized in real time after switching.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for HSS master / standby management. Background technique [0002] As an important part of the communication network, the Home Subscriber Server (HSS) is mainly used to store user data and subscription data, and provide data services to network elements that initiate requests. Therefore, software or Hardware failures, such as planned downtime (version upgrade or periodic maintenance), sudden downtime (downtime or power outage), will directly cause some user data or business data to be unavailable, thus affecting the normal use of the communication network. [0003] Active / standby management is a technology to ensure device reliability. It can ensure that the backup device backs up data when the primary device is running normally. When the primary device fails, the system can switch the business to the backup device in time to ensure uninterrupted business. At...

Problems solved by technology

[0006] Embodiments of the present invention provide a method and device for HSS master / backup management, which are used to solve the existing problems in the prior art due to the health check of the HSS master node by detecting the network connection and the data synchronization relying too much on the database and poor flexibility. The HSS active and standby nodes cannot be switched in time, and cannot be synchronized in real time after the switch, resulting in service interruption, and the reliability and stability of the HSS equipment cannot be guaranteed.
