Network connection method, device and system

Abstract

The invention discloses a network connection method, device and system, and the method comprises the steps that a main service gateway receives a media bearer building notification transmitted by a mobile management entity; the main service gateway activates the MAC address of a media interface after the main service gateway receives the media bearer building notification; the main service gatewayis restarted when the main service gateway detects a fault of a media channel, so as to enable the mobile management entity to notify a standby service gateway of activating the MAC address after themobile management entity detects the fault; a base station builds the media channel with the standby service gateway; the base station notifies the mobile management entity of the successful buildingof the media channel, thereby achieving a purpose that a standby media channel is in seamless connection with a fault media channel. A user basically cannot perceive the business interruption, and anexternal network element cannot sense the change of the media channel. There is no need of special processing, and no ARP storm will appear.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular, to a network connection method, device, and system. Background technique [0002] In the communication core network equipment, in order to achieve high reliability of the equipment, the commonly used technology is to realize the switching between the main equipment and the standby equipment through the floating IP technology. Floating IP technology refers to: bind the only IP with the service network port of the main device, when the main device fails, bind and activate the same IP with the service network port of the backup device, and then the backup device will be upgraded to main. [0003] When using floating IP technology, it generally has the following characteristics: [0004] Because the binding relationship between the IP and the MAC address has changed, the peripheral devices interconnected with the active device and the backup device ne...

Problems solved by technology

[0005] The purpose of the embodiment of the present invention is to propose a method, device and system for network connection, aiming to solve how to realize the media channel HA method that does not require floating IP binding, and when switching occurs, the media channel can be guaranteed to be basically uninterrupted. Moreover, the relevant peripheral devices are completely unaware of the purpose of the change of the media channel.
