Embodiment 1

[0029] This embodiment provides a method for upgrading a virtual network element. Such as figure 1 As shown, it is a flow chart of the method for upgrading a virtual network element according to the first embodiment of the present invention.

[0030] Step S110, creating a virtual machine of the latest version.

[0031] A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment.

[0032] Virtual network elements include OMM virtual machines, OMP virtual machines and other service processing virtual machines. Upgrading the virtual network element is to upgrade the virtual machines in the virtual network element respectively.

[0033]The OMM (Operation Maintenance Module, Operation and Maintenance Module) virtual machine runs in the background and is used to monitor the working conditions of the digital program-controlled switch.

[0034] The OMP (Operation Manag...

Embodiment 2

[0043] The virtual network element in this embodiment may not adopt a redundant design, that is to say, the virtual machine in the virtual network element only has a primary virtual machine and no backup virtual machine.

[0044] If the virtual machine has no redundancy, you can pre-create the latest version of the virtual machine; when upgrading the primary virtual machine of a lower version, the virtual machine of the new version Synchronize data between primary virtual machines of different versions; switch the standby virtual machine of the new version to the primary virtual machine, switch the primary virtual machine of the lower version to the standby virtual machine and delete it. In this way, during the process of upgrading the virtual network element, the operation of the virtual network element will not stop, and the service operation will not be interrupted.

[0045] The virtual network element in this embodiment may also adopt a redundant design to improve the secu...

Embodiment 3

[0049] This embodiment further describes using the first OMP virtual machine to replace the active OMP virtual machine in the virtual network element, and online upgrading the standby OMP virtual machine in the virtual network element. Such as figure 2 Shown is a flow chart of a method for upgrading a virtual network element according to the third embodiment of the present invention. In this embodiment, the OMP virtual machines running in the virtual network element include: a third OMP virtual machine and a fourth OMP virtual machine. Wherein, the third OMP virtual machine serves as the primary OMP virtual machine, and the fourth OMP virtual machine serves as the standby OMP virtual machine.

[0050] Step S210, creating the latest version of the first OMP virtual machine.

[0051] Step 1, obtain a new configuration data file of the virtual network element.

[0052] The new configuration data file is generated by a new version of the OMM virtual machine.

[0053] Upgradin...

Abstract

The invention discloses a method and device for upgrading a virtual network element. The method comprises the following steps: creating the latest version of virtual machine; and using the latest version of virtual machine to seamless replace a corresponding virtual machine in the virtual network element to upgrade the virtual network element. According to the method and device disclosed by the invention, the virtual network element is used in a wireless communication system, and when the network element needs to be upgrade, the pre-created latest version of virtual machine is used for replacing the corresponding virtual machine in the virtual network element to upgrade the virtual network element. By adopting the method and device disclosed by the invention, even if in an upgrading process of the virtual network element, the virtual network element can still normally run and can normally provide business service.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a virtual network element upgrading method and device. Background technique [0002] In a wireless communication system, network element upgrade is a part of network function management. At present, physical network elements are used in the telecom operation network, and the upgrade process of the physical network elements inevitably involves power-off, upgrade, and restart of the network elements. However, during the period from when the physical network element is powered off to when the physical network element is restarted, the physical network element must not be able to provide any service. Moreover, since the online upgrade of the physical network element takes a long time, the physical network element will not be able to provide service services for a period of time when the network element is upgraded. Therefore, the existing network element upgrade meth...
