Synthesis VPN emergency system base on target network and control method thereof

Abstract

The invention relates to a comprehensive VPN stand-by system based on a target network and a control method thereof. The method comprises the following steps: after an SAU receives the trigger initial message reported by MSC / SSP / VLR, the trigger initial message is sent to a GSM service processing module or a CDMA service processing module; the judge of the calling flow and the called flow is performed; and the calling flow and the called flow are respectively processed and a ticket is obtained. The comprehensive VPN stand-by system and the control method overcome the shortcomings of the prior VPN emergency proposal, especially solve the problem of the deletion of calling tickets in a signaling interception method, provide the method for evading the charging risk, control the complexity of the design of the service logic, save the development expense and network resources, and save a large amount of cost relative to a method for full disaster recovery.

Description

technical field [0001] The invention relates to VPN, in particular to a comprehensive VPN emergency system based on a target network and a control method thereof. Background technique [0002] In recent years, the intelligent network has been widely used in various communication networks, especially in the field of mobile communication, and has developed rapidly in countries all over the world, including my country. The intelligent network business mainly covers PPS (GSM prepaid) business and integrated VPN (virtual private network) business. As the core shared equipment in the switching network element, the intelligent network platform has the highest security level. [0003] At present, the emergency methods for the mobile intelligent network platform mainly include the signaling interception method and the full disaster recovery method. These two methods are based on the whole network target network, using the same network structure design, such as figure 1 As shown, a...

AI Technical Summary

Problems solved by technology

[0060] The signaling interception method has the following deficiencies: one, this method cannot carry out automatic voice reminder for the short number call of the VPN user

When the user makes a call with a short number, the backup SAU cannot translate the real number of the short number, and only directly instructs the MSC / SSP / VLR to connect, so the user will hear a prompt similar to "You called the wrong number", which causes the user to complaint

2. This method will not perform bill record processing for any calls of VPN users. Since the MSC / SSP / VLR bills of VPN users on the CDMA network will be filtered by the billing center according to the ServiceKey, after this method is enabled, the CDMA network VPN users will not be billed, resulting in the loss of call charges during the fault

[0061] The full disaster recovery method has the following disadvantages: 1. The construction cost is high. The construction cost of a comprehensive VPN emergency system with complete business processing capabilities is consistent with the main platform of the existing network, and there is a long period of deployment and testing. The cost contingency approach is less acceptable to operators

2. The cost of maintenance is high. After the implementation of this method, the platform’s daily bureau data maintenance, version upgrade, and hardware maintenance will be consistent with the main platform

In this way, it needs to spend twice the manpower and material resources to maintain the main system and the backup system at the same time

3. The switching period is long. It takes 10 minutes from the detection of the backup emergency system to the failure of the main system to the official takeover of the backup system. In this way, there will be nearly 10 minutes of business blocking

This delay is too long for the emergency system and cannot meet the requirements of quickly guaranteeing business
