Problems solved by technology

Specifically, when a certain SBC fails and needs to be switched, the relevant CE equipment on the faulty SBC side and the disaster recovery SBC side, as well as the disaster recovery SBC itself, need to temporarily configure data. The disaster recovery switchover involves many network elements, and the operation process takes a long time. Longer; moreover, temporarily configure disaster recovery switching data, the correctness and reliability of the data cannot be guaranteed

Embodiment Construction

[0038]In the embodiment of the present invention, at least one disaster recovery SBC is configured, and the disaster recovery SBC virtually has all the SBC data corresponding to each active SBC; On the disaster CE, configure the same user IP address as the user IP address of the primary SBC being DR, and configure a subnet mask with more digits in the address mask than the address mask of the CE corresponding to the DR primary SBC. code; based on the static IP longest match principle, the data packets of the active SBC that is under disaster recovery are routed to the disaster recovery CE on the side of the disaster recovery SBC.

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] Such as figure 1 As shown, the embodiment of the present invention is based on the static IP longest match session border controller SBC disaster recovery method, comprising the following steps:

[0041] St...

Abstract

The invention discloses a static IP longest match-based session border controller (SBC) disaster recovery method, at least one disaster recovery SBC is configured, and the disaster recovery SBC virtual has all SBC data corresponding to each active SBC; When the active SBC performs disaster recovery, configure the user IP address and subnet mask on the disaster recovery client-side edge device (CE) of the disaster recovery SBC. The same, and the number of address mask digits of the subnet mask is more than the number of address mask digits of CE corresponding to the active SBC being disaster-tolerant; based on the principle of longest match of static IP, the active SBC The data packets are routed to the disaster recovery CE on the side of the disaster recovery SBC. The invention also discloses an SBC disaster recovery system and a disaster recovery switch control device based on the static IP longest match.

Description

technical field [0001] The present invention relates to a session border controller (SBC, Session Border Controller) disaster recovery technology, in particular to an SBC disaster recovery method, system and device based on static IP longest match. Background technique [0002] IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) is a communication system that realizes integrated communication of voice, video, and data. The SBC in this system is the first point of equipment for user terminal access. availability. In order to realize the failure of any SBC in the IMS system, the standby SBC device can be quickly enabled to take over, and it is necessary to build a disaster recovery architecture of the SBC. [0003] With the continuous growth of IMS network users, higher requirements are put forward for the service reliability of the IMS network, especially the border control device of the IMS network - SBC. Since SBCs are deployed in different regions and there are a larg...
