It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

A network switching method is provided in this embodiment. FIG. 1 is a flowchart of a network switching method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps S101-S103:

S101. When the router is connected to the first network, the router monitors whether the router is connected to the fixed network device.

S102. When it is detected that the router is connected to the fixed network device, the router acquires an Internet Protocol IP address of the second network corresponding to the fixed network device.

S103. The router switches from the first network to the second network according to the IP address.

Through the above steps, when the router is connected to the first network, the router monitors that the router is connected to the fixed network device, indicating that the router acquires the opportunity to connect to the fixed network, that is, the second network, and acquires the IP of the second network at the router. After the address, the first network can be switched to the second network. The problem that the related technology can only switch between the data network and the fixed network can be solved manually, thereby realizing the automatic switching between the data network and the fixed network, thereby improving the user experience.

In the above step S102, the router obtains the Internet Protocol IP address of the second network corresponding to the fixed network device. Before the router obtains the IP address, one or more necessary steps are required, which will be exemplified below.

Optionally, before the router acquires an Internet Protocol IP address of the second network corresponding to the fixed network device, the router sends an application message to the fixed network device, where the application message is used to apply to the fixed network device. IP address. So that the fixed network device allocates the above IP address to the router according to the application information sent by the router.

After the router sends the application message to the fixed network device, the router may not obtain the IP address connected to the second network. Therefore, after the router is connected to the fixed network device, the terminal cannot obtain the terminal. In the case of the IP address, the router maintains a connection with the first network.

Optionally, after the router switches from the first network to the second network according to the IP address, check whether the link connected to the second network by the router is unobstructed, and the result of the check is that the router is connected to the second network. In the case that the link is unobstructed, the router maintains a connection with the second network. If the result of the check is that the link of the router to the second network is not smooth, the router is switched from the second network to the first network. The detection method may include a plurality of types, for example, after checking that the multiplexed Ethernet port of the router is connected to the external device and the ip address is obtained from the external device, the route is The ping packet is sent to the Ethernet card connected to the external server to detect whether the fixed network link is normal. The destination address of the ping packet is the gateway address of the server. For example, the ping packet command is: ping 10.10.10.10–I eth0. If the returned ping packet is received within the timeout period, the fixed network link is unobstructed. At this time, the fixed network link is maintained. If the returned ping packet cannot be received within the unit time, the fixed network link is different. To the 4G network, where the timeout can be set to 5 seconds.

Optionally, the fixed network device includes one or more of the following: a Pppoe server and a dhcp server.

With the rapid development of the Internet, especially the rapid development and popularization of 4G and fixed network services, router equipment is widely used as a relatively portable communication terminal. It can choose different uplinks as the uplink channel to access the router. The client provides access to the Internet service. Currently, the optional uplink channels include: 4G gateway mode and wired broadband mode (where the wired broadband mode includes wired broadband dhcp and wired broadband pppoe). These two modes have their own characteristics: fixed network (router is in wired broadband mode), especially fiber-optic network has the characteristics of stable Internet access and fast network speed, but the cost of fixed network laying is high; 4G Internet access is not affected by the environment, just insert SIM After the card is 4G dialed, the Internet can be accessed, but the disadvantage is that the tariff is higher. Therefore, a better method is to use wired broadband Internet access in a fixed network environment, and use 4G dial-up Internet access in an environment without a fixed network. However, at present, the router device can only manually select 4G dial-up or use the fixed network. To complete the switchover between the two, the user needs to manually complete the page, and the user experience is not good.

For the above problem, the present embodiment provides a method for automatically switching between a 4G dial-up network and a fixed network. The user can formulate a differentiated switching policy according to the 4G priority or the fixed network priority. The method is: the device is powered on. After that, the default is 4G dial-up Internet access and 4G priority. When the network port connected to the fixed network on the router is detected, the device automatically initiates pppoe dialing application ip, and the device applies for ip through dhcp. If the fixed network method applies to ip, the current online mode will be automatically switched to wired broadband pppoe or wired broadband dhcp, and the user will normally access the Internet; if the pppoe server is detected but the authentication fails, it is judged whether it is 4G priority or fixed network priority, if it is 4G first The current mode is set to 4G dialing. If the fixed network priority is set, the current mode is set to the wired broadband pppoe. When the subsequent user accesses the webpage through the browser, the page is redirected to the page where the user name and password are set by pppoe. Regardless of whether the router is currently in the 4G dialing mode or in the wired broadband mode, as long as the device obtains the ip address through the fixed network, the internal periodicity of the device (for example, the period is set to 30 seconds) monitors whether the fixed network path is unobstructed, and if it is smooth, it remains. Fixed network or switch from 4G to fixed network, if not, keep the current mode unchanged.

This embodiment proposes a device for implementing mutual switching between a router 4G Internet access and a fixed online network.

6 is a block diagram of a module for implementing a 4G Internet access and a fixed network interconnection device according to an embodiment of the present invention. As shown in FIG. 6, the device involves four modules, namely, a fixed network module and a solid-state module. The network applies for an ip module, a monitoring fixed network link smoothing module (corresponding to the above checking module 52), and a mode automatic switching module (corresponding to the above switching module 26). The fixed network module is used to monitor whether the router is currently connected to the external fixed network device through the network cable. If it is found that the external device is connected, it is necessary to identify whether the current connection is a pppoe server or a dhcp server; applying to the fixed network for the ip module is responsible for sending the pppoe. The request and the dhcp request apply for an ip address to the fixed network; if the ip address assigned to the fixed network is obtained, the monitoring of the fixed network link patency module inside the router periodically detects whether the link from the router to the fixed network gateway is unobstructed; The module is responsible for determining whether to perform mode switching based on the detection result.

FIG. 7 is a flowchart of a method for implementing mutual switching between a 4G Internet access and a fixed online network according to an embodiment of the present invention. The following describes the entire function by using the functional flowchart shown in FIG. 7:

In the first step, the device defaults to 4G gateway mode after booting. Therefore, it is first determined whether the current device is in 4G gateway mode. If not, it is modified to 4G gateway mode, and the routing related parameters are modified to 4G gateway corresponding parameters, and the routing parameters thereof. Including but not limited to dns address, firewall rules, etc.

In the second step, the "discovery fixed network module" is responsible for periodically monitoring whether the router is connected to an external fixed network device, wherein the fixed network device includes but is not limited to a pppoe server or a dhcp server. The discovery method is to monitor whether it is connected to an external device at the driver level.

In the third step, if the router is not connected to the external device, the 4G gateway mode is maintained; if the router is connected to the external device, the router sends an application ip request to the external device, and the sent request includes but is not limited to the pppoe request and the dhcp request. If the ip address is not applied from the fixed network device to perform the fourth step, otherwise the fifth step is performed.

The fourth step is to determine whether the external device connected to the router is detected as a pppoe server: if it is not a pppoe server, set the mode to 4G gateway mode and perform the second step; if it is a pppoe server, determine whether the default is fixed network priority or 4G gateway priority. If it is a fixed network priority, set the mode to wired broadband pppoe and continue to monitor whether the connected fixed network device changes. If it is not the fixed network priority, the 4G gateway takes precedence. At this time, the current mode is set to 4G gateway mode. And perform the second step.

In the fifth step, it is determined whether the external device connected to the router is detected as a pppoe server: if it is not a pppoe server, the mode is set to the wired broadband dhcp mode, otherwise the mode is set to the wired broadband pppoe mode. At this time, due to the change of the router uplink path, specifically, the wan side network card changes (for example, the usb0 of the wan side network card from the 4G gateway changes to the eth0 of the wired broadband), Therefore, it is necessary to update the parameters related to this. The parameters to be updated include, but are not limited to, the routing table, the firewall rule, the router dns address, and the 4G connection needs to be disconnected because the uplink path is switched from the 4G gateway mode to the wired broadband mode.

However, no matter which mode is set, it indicates that the ip has been applied from the fixed network, and it is necessary to periodically check whether the link to the fixed network is smooth, and the sixth step is performed.

The sixth step, if unobstructed, indicates that the fixed network path is working normally and continues to maintain the current working mode; if it is not smooth, it may be due to the arrears of the fixed network or the network cable has been pulled out, etc. step.

As shown in FIG. 7, the flowchart includes the following steps S701-S708:

S701. Determine whether the current mode is the 4G gateway mode. If the determination result is YES, execute step S702. If the determination result is negative, execute step S703.

S702. Maintain a 4G gateway module.

S703 is set as a 4G gateway module.

S704. Monitor whether the router is connected to the fixed network.

S705. Determine whether the router is connected to the fixed network. If the determination result is no, step S702 is performed. If the determination result is yes, step S706 is performed.

S706. Apply for a fixed network IP.

S707. Determine whether the application for the fixed network IP is successful. If the application is successful, step S708 is performed. If the application is unsuccessful, step S713 is performed.

S708, whether the pppoe server is found, if the determination result is yes, step S709 is performed, and if the determination result is no, step S710 is performed.

S709. The setting mode is a wired broadband pppoe.

S710. The setting mode is a wired broadband dhep.

S711, update the router parameters.

S712. Periodically detecting the patency of the fixed network link.

S713. Determine whether the fixed network is unobstructed. If the determination result is yes, step S714 is performed. If the determination result is no, step S715.

S714. Maintain the current fixed network mode.

S715. It is determined whether the pppoe server is found. If the determination result is YES, step S717 is performed. If the determination result is negative, step S716 is performed.

S716, set to 4G gateway mode.

S716, fixed network priority.

S717, the setting mode is wired broadband pppoe.

In summary, the pppoe server is inserted into the WAN port of the router through the network cable, and the router recognizes that the pppoe server is currently connected, and sets the mode to the wired broadband pppoe mode. After the dialing succeeds, the router obtains from the pppoe server. Public network ip, you can go online. Insert a pppoe server into the WAN port of the router through the network cable. The router recognizes that the current connection is a pppoe server, and sets the mode to wired broadband pppoe mode. After entering the wrong username and password, the router cannot obtain the public network ip address. In the case of wired broadband priority, the current mode is the wired broadband pppoe mode, and the current mode is set to 4G gateway mode under the priority of the 4G gateway. Insert a dhcp server into the WAN port of the router through the network cable. The router recognizes that the current connection is a dhcp server, and sets the mode to wired broadband dhcp mode. After the dialup is successful, the router obtains the public network ip from the dhcp server and can access the Internet. The router's WAN port does not connect to any external device, and the router sets the mode to 4G gateway mode. After the router switches from 4G gateway mode to wired broadband mode, the routing table, firewall rules, and router dns address are all updated to wired broadband mode. When the mode is switched to wired broadband, the 4G connection is successfully disconnected. The dynamic automatic switching between the 4G Internet access and the fixed online network on the router is realized, which satisfies the needs of users in different scenarios and improves the user experience.
