Configuration method and configuration device for long-distance branch device

Abstract

The invention provides a configuration method and a configuration device for a long-distance branch device. After receiving a configuration short message from a headquarter server, a the long-distance branch gateway device dials up a mobile network and sends the internet protocol (IP) address which is obtained from dial-up of the mobile network to the headquarter server, the headquarter server sends supplement configuration information to the long-distance branch gateway device according to the IP address, the long-distance branch gateway device establishes a virtual private network (VPN) tunnel between the headquarter server and the long-distance branch gateway device according to the supplement configuration information, and then the headquarter server manages and controls the long-distance branch gateway device through the established VPN tunnel. By means of the configuration method and the configuration device for the long-distance branch device, in the configuration of the long-distance branch gateway device, no specialized person is needed in the configuration of a route in site, no need of mastering device configuration technology to power on the long-distance branch gateway device, configuration can be completed automatically, and thus plenty of time and economic cost are saved for a user.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for configuring remote branch equipment. Background technique [0002] With the continuous investment and construction of mobile networks by operators, the services of mobile networks are also becoming more and more perfect. The mobile network itself has the characteristics of low cost, mobility, and easy installation, making more and more enterprises adopt mobile access as an ideal choice for enterprise information construction. However, how to ensure the security of mobile access, the confidentiality of business transmission, and the convenience of large-scale deployment and management still plague enterprise users. [0003] Such as figure 1 As shown in the figure, it is a typical network diagram for an enterprise to access internal branches through a mobile network. In this application scenario, the gateway equipment for mobile access needs to be con...

Problems solved by technology

However, such configuration information is generally more, and the carrying capacity of short messages is limited, making it difficult for one short message to carry all the configuration information. The processing of reorganization increases the burden and possibility of error on the headquarters network management and branch equipment

At the same time, there may be unpredictable situations such as loss and out-of-order text messages, which also brings the possibility of device processing errors.

In addition, sending SMS is also costly, and sending multiple SMS directly leads to an increase in user management costs
