[0002] With the development of mobile communication technology, more and more gateway devices support dial-up Internet access using multiple Internet access modes. Usually, the terminal user needs to manually set the Internet access mode of the gateway device. If the current Internet access mode of the gateway device cannot access the Internet, the terminal user needs to manually change the Internet access mode, which is not only cumbersome to operate, but also leads to a poor user experience for the terminal user.

[0003] The inventors learned that although intelligent switching of Internet access modes has been achieved in the prior art, the conditions for determining whether the Internet access mode needs to be switched are relatively simple and cannot cover all situations. It may happen that the terminal user cannot access the Internet due to failure to switch the mode in time. In addition, the current switching methods do not take into account the problem of IPV6 connection, which will cause trouble to users who use IPV6 to connect to the Internet.

[0026] As mentioned in the background technology, it is difficult in the prior art to accurately determine whether the EWAN connection is online in various situations. In order to solve the above problem, in a typical implementation of the present application, a method for switching the Internet access mode of a gateway device, a switching device, a computer-readable storage medium and an intelligent switching system are provided.

[0027] According to an embodiment of the present application, a method for switching an Internet access mode of a gateway device is provided.

[0028] Figure 1 1 is a flow chart of a method for switching an Internet access mode of a gateway device according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0029] Step S101, obtaining a DNS (Domain Name System, DNS for short) detection domain name, the DNS detection domain name is a predefined DNS domain name;

[0030] Step S102, determining whether an EWAN (Ethernet Wide Area Network, EWAN for short) connection is online at least according to the DNS detection domain name, the EWAN connection being a network connection in which the gateway device is in EWAN mode;

[0031] Step S103, when the EWAN connection is offline, switching the Internet access mode of the gateway device to LTE (Long Term Evolution, LTE for short) mode.

[0032] In the method for switching the Internet access mode of the above-mentioned gateway device, first, a DNS detection domain name is obtained, and then, at least according to the obtained DNS detection domain name, it is determined whether the EWAN connection is online. Finally, when it is determined that the EWAN connection is offline, the Internet access mode of the above-mentioned gateway device is switched to the LTE mode, wherein the DNS detection domain name is a predefined DNS domain name, and the EWAN connection is a network connection of the above-mentioned gateway device in the EWAN mode. Compared with the prior art in which whether to switch the Internet access mode to the LTE mode is determined according to whether the WAN port is plugged into a network cable, the present solution realizes determining whether the EWAN connection is online at least according to the obtained DNS detection domain name, that is, at least according to the DNS detection domain name, the EWAN connection established using each IP protocol can be detected, ensuring that it can be more effectively determined whether the EWAN connection is online, and can more accurately detect whether the EWAN connection is online in all situations. When it is determined that the EWAN connection is offline, the Internet access mode of the gateway device is switched to the LTE mode, realizing the intelligent switching of the Internet access mode of the above-mentioned gateway device, ensuring the continuity of the terminal user device network, thereby solving the problem in the prior art that it is difficult to accurately determine whether the EWAN connection is online in each situation.

[0033] In actual application, the above-mentioned gateway device can be a router, but is not limited to a router, and can also be other gateway devices. In addition, the above-mentioned IP protocol can be an IPV4 protocol, and can also be an IPV6 protocol.

[0034] In addition, it should be noted that the above DNS detection domain name can be a user-defined detection domain name.

[0035] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] In order to more effectively and timely determine whether the above-mentioned EWAN connection is online, in an embodiment of the present application, whether the EWAN connection is online is determined at least based on the above-mentioned DNS detection domain name, including: determining whether the connection using IP protocol dial-up Internet access is offline at least based on the above-mentioned DNS detection domain name; when at least one of the above-mentioned IP protocol (Internet Protocol, IP protocol for short) dial-up Internet access connections is offline, determining that the above-mentioned EWAN connection is offline.

[0037] In actual application, if the Internet access mode of the above-mentioned gateway device is the EWAN mode, in the above-mentioned EWAN mode, if the above-mentioned gateway device establishes an Internet connection through the IPV4 (Internet Protocol Version 4, IPV4 for short) protocol, it can at least be determined based on the above-mentioned DNS detection domain name to determine whether the above-mentioned EWAN connection is offline; if the above-mentioned gateway device establishes an Internet connection through the IPV6 (Internet Protocol Version 6, IPV6 for short) protocol, it can at least be determined based on the above-mentioned DNS detection domain name to determine whether the above-mentioned EWAN connection is offline; if the above-mentioned gateway device establishes an Internet connection through the IPV4 and IPV6 protocols, it can at least be determined based on the above-mentioned DNS detection domain name to determine whether the above-mentioned EWAN connection is offline.

[0038] In a specific embodiment of the present application, when the above-mentioned device establishes an Internet connection using the IPV4 protocol or the IPV6 protocol, as long as the Internet connection established using the IPV4 protocol or the Internet connection established using the IPV6 protocol is offline, the gateway device will switch to LTE dial-up Internet access; when the Internet connection established using the IPV4 protocol or the Internet connection established using the IPV6 protocol is restored online, the above-mentioned gateway device will disconnect the LTE dial-up Internet connection and restore to the EWAN connection.

[0039] In another embodiment of the present application, at least according to the above-mentioned DNS detection domain name, determining whether the connection using the IP protocol dial-up Internet access is offline includes: based on the above-mentioned IP protocol, sending the above-mentioned DNS detection domain name to the DNS server; in the case where the above-mentioned DNS detection domain name is queried in the above-mentioned DNS server, determining that the connection using the IP protocol dial-up Internet access is online; in the case where the above-mentioned DNS detection domain name is not queried in the above-mentioned DNS server, determining that the connection using the IP protocol dial-up Internet access is offline. In this embodiment, whether the above-mentioned connection using the IP protocol dial-up Internet access is online is determined based on whether the above-mentioned DNS detection domain name is queried in the above-mentioned DNS server, which ensures that the method for determining whether the connection using the IP protocol dial-up Internet access is offline is relatively flexible, and it is possible to determine whether the above-mentioned connection using the IP protocol dial-up Internet access is online in a relatively timely manner.

[0040] In actual application, when the gateway device can support single detection, that is, the user customizes the DNS detection domain name, and when the gateway device can query the DNS server for the DNS detection domain name, it is considered that the established EWAN connection is online.

[0041] In order to more accurately determine whether the connection using the IP protocol to dial up to the Internet is offline, and further ensure the continuity of the terminal user device network, in another embodiment of the present application, at least based on the above-mentioned DNS detection domain name, determine whether the connection using the IP protocol to dial up to the Internet is offline, including: obtaining a preset IP address; based on the above-mentioned IP protocol, sending the above-mentioned DNS detection domain name to the DNS server; when the above-mentioned DNS detection domain name is queried in the above-mentioned DNS server and the above-mentioned preset IP address is connectable, determine that the connection using the above-mentioned IP protocol to dial up to the Internet is online; when the above-mentioned DNS detection domain name is not queried in the above-mentioned DNS server, and / or the above-mentioned preset IP address is not connectable, determine that the connection using the above-mentioned IP protocol to dial up to the Internet is offline.

[0042] It should be noted that the above-mentioned preset IP address can be any IP address input by the user, and it only needs to be able to be used for Ping IP to detect the connectivity of the network.

[0043] In actual application, when the above-mentioned gateway device can support dual detection, the user can customize the DNS detection domain name and Ping IP address. When the above-mentioned gateway device can query the above-mentioned DNS detection domain name from the DNS server and can ping the customized IP address, the EWAN connection is considered to be online, otherwise the EWAN connection is considered to be offline.

[0044] In addition, the above-mentioned single detection method and the above-mentioned double detection method allow users to flexibly customize the offline conditions of the above-mentioned EWAN connection. When the front-end of the gateway device is disconnected from the Internet, but there is a DNS cache or DNS proxy, a single DNS detection will still consider the connection to be online. However, the use of double DNS+ping detection can determine that the network is offline and switch to LTE mode to access the Internet, which can ensure the continuity of the network of the end-user device.

[0045] In another embodiment of the present application, when multiple IP protocol dial-up Internet access is used at the same time, when at least one of the IP protocol dial-up Internet access connections is offline, determining that the EWAN connection is offline includes: when all the IP protocol dial-up Internet access connections are offline, determining that the EWAN connection is offline. In this embodiment, when multiple IP protocol dial-up Internet access is used, when it is determined that all the IP protocol dial-up Internet access connections are offline, determining that the EWAN connection is offline, this not only further ensures that the determination result of the EWAN connection being offline is relatively accurate, but also further ensures that the user's traffic charges can be reduced as much as possible.

[0046] In a specific embodiment of the present application, when the above-mentioned gateway device establishes an Internet connection using IPV4 and IPV6 protocols, the above-mentioned gateway device will switch to LTE dial-up Internet access only when the Internet connection established using the IPV4 protocol and the Internet connection established using the IPV6 protocol are both offline; when any one of the connections is restored online, the gateway device will disconnect the LTE dial-up Internet access and restore to the above-mentioned EWAN connection.

[0047] In order to ensure that the traffic charges are consumed as little as possible, in one embodiment of the present application, after the Internet access mode of the above-mentioned gateway device is switched to the LTE mode, the above-mentioned switching method also includes: sending request information at predetermined intervals, and determining again whether the above-mentioned EWAN connection is online, and the above-mentioned request information is used to request connection to the above-mentioned EWAN connection; when the above-mentioned EWAN connection is online, disconnecting the above-mentioned LTE mode, and switching the above-mentioned Internet access mode of the above-mentioned gateway device to the above-mentioned EWAN mode. In this embodiment, after the Internet access mode of the above-mentioned gateway device is switched to the LTE mode, the above-mentioned EWAN connection will be reconnected at regular intervals and the above-mentioned EWAN connection will be detected to be online. This not only further ensures that uninterrupted network services can be provided to the user terminal device, but also reduces the traffic charges of the user terminal device.

[0048] In order to further ensure that the traffic charges are consumed as little as possible, in another embodiment of the present application, determining whether the above-mentioned EWAN connection is online includes: when at least one of the above-mentioned IP protocol dial-up Internet access connections is online, determining that the above-mentioned EWAN connection is online.

[0049] The embodiment of the present application also provides a switching device for the Internet access mode of a gateway device. It should be noted that the switching device for the Internet access mode of a gateway device in the embodiment of the present application can be used to execute the switching method for the Internet access mode of a gateway device provided in the embodiment of the present application. The following introduces the switching device for the Internet access mode of a gateway device provided in the embodiment of the present application.

[0053] The switching unit 30 is used to switch the Internet access mode of the gateway device to the LTE mode when the EWAN connection is offline.

[0054] In the switching device for the Internet access mode of the above-mentioned gateway device, the acquisition unit is used to acquire a DNS detection domain name, and the above-mentioned DNS detection domain name is a predefined DNS domain name; the determination unit is used to determine whether the EWAN connection is online at least according to the above-mentioned DNS detection domain name, and the above-mentioned EWAN connection is a network connection of the above-mentioned gateway device in the EWAN mode; the switching unit is used to switch the Internet access mode of the above-mentioned gateway device to the LTE mode when the above-mentioned EWAN connection is offline. Compared with the prior art in which whether to switch the Internet access mode to the LTE mode is determined according to whether the WAN port is plugged into a network cable, the present solution realizes determining whether the above-mentioned EWAN connection is online at least according to the above-mentioned DNS detection domain name obtained, that is, at least according to the DNS detection domain name, the EWAN connection established by each IP protocol can be detected, ensuring that it can be more effectively determined whether the above-mentioned EWAN connection is online, and can more accurately detect whether the above-mentioned EWAN connection is online in all situations. When it is determined that the above-mentioned EWAN connection is offline, the Internet access mode of the gateway device is switched to the LTE mode, realizing the intelligent switching of the Internet access mode of the above-mentioned gateway device, ensuring the continuity of the terminal user device network, thereby solving the problem in the prior art that it is difficult to accurately determine whether the EWAN connection is online in various situations.

[0055] In actual application, the above-mentioned gateway device can be a router, but is not limited to a router, and can also be other gateway devices. In addition, the above-mentioned IP protocol can be an IPV4 protocol, and can also be an IPV6 protocol.

[0056] In addition, it should be noted that the above DNS detection domain name can be a user-defined detection domain name.

[0059] In a specific embodiment of the present application, when the above-mentioned device establishes an Internet connection using the IPV4 protocol or the IPV6 protocol, as long as the Internet connection established using the IPV4 protocol or the Internet connection established using the IPV6 protocol is offline, the gateway device will switch to LTE dial-up Internet access; when the Internet connection established using the IPV4 protocol or the Internet connection established using the IPV6 protocol is restored online, the above-mentioned gateway device will disconnect the LTE dial-up Internet connection and restore to the EWAN connection.

[0060] In another embodiment of the present application, the first determination module includes a first sending submodule, a first determining submodule and a second determining submodule, wherein the first sending submodule is used to send the DNS detection domain name to the DNS server based on the IP protocol; the first determining submodule is used to determine that the connection for dialing up the Internet using the IP protocol is online when the DNS detection domain name is queried in the DNS server; the second determining submodule is used to determine that the connection for dialing up the Internet using the IP protocol is offline when the DNS detection domain name is not queried in the DNS server. In this embodiment, whether the connection for dialing up the Internet using the IP protocol is online is determined based on whether the DNS detection domain name is queried in the DNS server, which ensures that the method for determining whether the connection for dialing up the Internet using the IP protocol is offline is more flexible and can determine whether the connection for dialing up the Internet using the IP protocol is online in a more timely manner.

[0061] In actual application, when the gateway device can support single detection, that is, the user customizes the DNS detection domain name, and when the gateway device can query the DNS server for the DNS detection domain name, it is considered that the established EWAN connection is online.

[0062] In order to more accurately determine whether the connection for dial-up Internet access using the IP protocol is offline, and further ensure the continuity of the terminal user device network, in another embodiment of the present application, the above-mentioned first determination module includes an acquisition submodule, a second sending submodule, a third determination submodule and a fourth determination submodule, wherein the above-mentioned acquisition submodule is used to obtain a preset IP address; the above-mentioned second sending submodule is used to send the above-mentioned DNS detection domain name to the DNS server based on the above-mentioned IP protocol; the above-mentioned third determination submodule is used to determine that the connection for dial-up Internet access using the above-mentioned IP protocol is online when the above-mentioned DNS detection domain name is queried in the above-mentioned DNS server and the above-mentioned preset IP address is connectable; the above-mentioned fourth determination submodule is used to determine that the connection for dial-up Internet access using the above-mentioned IP protocol is offline when the above-mentioned DNS detection domain name is not queried in the above-mentioned DNS server and / or the above-mentioned preset IP address is not connectable.

[0063] It should be noted that the above-mentioned preset IP address can be any IP address input by the user, and it only needs to be able to be used for Ping IP to detect the connectivity of the network.

[0064] In actual application, when the above-mentioned gateway device can support dual detection, the user can customize the DNS detection domain name and Ping IP address. When the above-mentioned gateway device can query the above-mentioned DNS detection domain name from the DNS server and can ping the customized IP address, the EWAN connection is considered to be online, otherwise the EWAN connection is considered to be offline.

[0065] In addition, the above-mentioned single detection method and the above-mentioned double detection method allow users to flexibly customize the offline conditions of the above-mentioned EWAN connection. When the front-end of the gateway device is disconnected from the Internet, but there is a DNS cache or DNS proxy, a single DNS detection will still consider the connection to be online. However, the use of double DNS+ping detection can determine that the network is offline and switch to LTE mode to access the Internet, which can ensure the continuity of the network of the end-user device.

[0066] In another embodiment of the present application, the second determination module includes a fifth determination submodule, and the fifth determination submodule is used to determine that the EWAN connection is offline when multiple IP protocol dial-up connections are simultaneously used and each of the IP protocol dial-up connections is offline. In this embodiment, when multiple IP protocol dial-up connections are used, when it is determined that all of the IP protocol dial-up connections are offline, the EWAN connection is determined to be offline, which not only further ensures that the determination result of the EWAN connection being offline is relatively accurate, but also further ensures that the user's traffic charges can be reduced as much as possible.

[0067] In a specific embodiment of the present application, when the above-mentioned gateway device establishes an Internet connection using IPV4 and IPV6 protocols, the above-mentioned gateway device will switch to LTE dial-up Internet access only when the Internet connection established using the IPV4 protocol and the Internet connection established using the IPV6 protocol are both offline; when any one of the connections is restored online, the gateway device will disconnect the LTE dial-up Internet access and restore to the above-mentioned EWAN connection.

[0068] In order to ensure that the traffic charges are consumed as little as possible, in one embodiment of the present application, after the Internet access mode of the above-mentioned gateway device is switched to the LTE mode, the above-mentioned switching device also includes a sending unit and a disconnecting unit, wherein the above-mentioned sending unit is used to send request information at predetermined intervals and determine again whether the above-mentioned EWAN connection is online, and the above-mentioned request information is used to request to connect to the above-mentioned EWAN connection; the above-mentioned disconnecting unit is used to disconnect the above-mentioned LTE mode when the above-mentioned EWAN connection is online, and switch the above-mentioned Internet access mode of the above-mentioned gateway device to the above-mentioned EWAN mode.

[0072] like Figure 3 As shown, the gateway device has two Internet access modes: LTE mode and EWAN mode. When the gateway device runs in EWAN mode, it will establish an EWAN connection and periodically detect whether the EWAN connection is online. If it detects that the EWAN connection is offline, the gateway device will automatically switch to LTE mode. When the gateway device switches to LTE mode, it will periodically reconnect the EWAN connection and detect whether the EWAN connection is online. When it is confirmed that the EWAN connection is back online, the gateway device will automatically disconnect the LTE mode and switch back to the EWAN mode. This intelligent Internet access mode switching method can achieve the purpose of providing uninterrupted network services for terminal devices while consuming as little traffic charges as possible.

[0073] In addition, the Internet access mode switching method of this scheme also supports the online detection of IPV4 protocol, IPV6 protocol and IPV4 and IPV6 protocols in EWAN mode. First, determine whether the current Internet access mode of the above-mentioned gateway device is LTE mode. When the current Internet access mode of the above-mentioned gateway device is LTE mode, and the above-mentioned gateway device is a connection established by IPV4 or a connection established by IPV6, then detect whether the connection established by IPV4 is online. When it is determined that the connection established by IPV4 is online, it is determined that the reconnection to the EWAN connection is successful; when the connection established by IPV4 is not online, then detect whether the connection established by IPV6 is online. When it is detected that the connection established by IPV6 is online, it is determined that the reconnection to the EWAN connection is successful. When it is detected that the connection established by IPV6 is not online, the Internet access mode of the above-mentioned gateway device still adopts LTE mode, that is, this scheme realizes that when the Internet access connection is established by the IPV4 protocol or the Internet access connection is established by the IPV6 protocol, as long as the connection is offline, the above-mentioned gateway device will still use the LTE mode to access the Internet. If the EWAN connection is reconnected successfully, the terminal device will disconnect from the LTE mode and return to the EWAN connection to the Internet. When the above-mentioned gateway device uses the IPV4 protocol and the IPV6 protocol to establish an Internet connection, the gateway device will disconnect the EWAN connection and enable the LTE mode only when the Internet connection established using IPV4 and the Internet connection established using IPV6 are both offline; when any of the connections is restored online, the gateway device will disconnect from the LTE mode and return to the EWAN connection to the Internet.

[0074] Example 2

[0075] like Figure 4 As shown, when the gateway device supports single detection and dual detection, when the user selects single detection, the user can customize the DNS detection domain name. If the gateway device can query the address of the domain name from the DNS server (that is, the DNS detection is successful), the connection is considered online. When the user selects dual detection, the user can customize the DNS detection domain name and ping IP address; if the gateway device can query the domain name address from the DNS server and can ping the customized IP address (that is, the Ping detection is successful), the IPV4 (IPV6) connection detection is considered online, otherwise the IPV4 (IPV6) connection detection is considered offline. The above detection method allows users to flexibly customize the offline conditions of the EWAN connection, and when the front end of the gateway device is disconnected from the network, but there is a DNS cache or DNS proxy, a single DNS detection will still be considered online, but the use of dual DNS+ping detection can determine that the network is offline and switch to LTE mode to access the Internet, ensuring the continuity of the terminal user device network.
