Description
Technical Field
The invention relates to a communication technology, in particular to a 4GVPDN networking technology in the communication field.
Background
VPDN (Virtual Private Dial-up Network) refers to a method of accessing to the internet in a Dial-up manner, forming Private data by encapsulating and encrypting Network data, and transmitting the Private data on the public Network, so as to achieve the security level of the Private Network. The VPDN user can be connected with the user network in the user through a virtual secure channel through a public network, and the user on the public network can not access the resource in the user network through the virtual channel. The VPDN network is a typical network service of the 4G private network, and is generally applied to: enterprises, government departments and the like remotely access and mobile office, and the enterprises build the largest-range enterprise extranet, internet access service providers and application service providers by utilizing the China telecommunication network to develop value-added services by utilizing a public platform.
Corresponding to specific applications, dual 4G or multi 4G application scenarios (i.e. more than one 4GVPDN line is built at the same time) are also generally accepted by user groups. Because each 4G line needs an account to establish a dial-up connection, a network automation deployment technology of multi-operator account switching and master-slave account switching is involved.
Because many users of VPDN services use different operators to perform different services, and dial account configurations (including APN, user name and password) provided by different operators are different, when a user wants to switch to another operator to perform a service, the user needs to manually perform reconfiguration, which is very troublesome.
At present, there is a scheme that provides a multi-account list mechanism, that is, a router may configure multiple dialing accounts at the same time, if each account represents an operator, when a user wants to switch the operator, the user only needs to change a Subscriber Identity Module (SIM) card of the corresponding operator, the router may automatically dial from a first dialing account, if the first dialing fails, the next dialing account is used, and so on, until the first dialing fails, after a cycle, if the dialing fails, the router restarts the modem, and then redials again from the first dialing account, which is a dead board, and has the following disadvantages: 1. the slower the dialing speed, the more accounts configured, the longer the time to find the correct dialing configuration may be; 2. when the SIM card is under-charged or the line is in fault, even if the correct dialing configuration cannot be used for successful dialing, the method cannot detect such problems, and still continues to poll and switch, which occupies resources and is meaningless.
