In the smart home system, a home gateway is usually used to access the smart home terminal to the internet, so as to provide rich, diversified, personalized, convenient, comfortable, safe and efficient services for people. Fig. 1 provides a smart home network system in the prior art. Referring to fig. 1, the intelligent home network system includes a remote management device 101, a home gateway 102, and an intelligent home terminal 103. The smart home terminal 103 accesses the home gateway 102, and the home gateway 102 establishes a communication connection with the remote management device 101. The remote management device 101 provides remote management services for the home gateway 102, and the home gateway 102 is used for connecting the smart home terminal 103 to a network.
The home gateway may support remote control, detection and configuration. At present, a home gateway deployed by a telecommunications operator can support two virtual local area network (virtual local area network) channels, which are an internet channel and a remote management (TR069) channel, to support different services. The internet channel is open to the user and is used for forwarding service data of the user, such as data of surfing the internet, playing games and watching videos of the user. The TR069 channel is open to telecommunication operators, and can only be used for remotely managing the home gateway, for example, modifying parameters of the home gateway, upgrading a software version of the home gateway, and the like, and cannot carry any service data. For example, in the smart home network system shown in fig. 1, an internet channel is used between the home gateway 102 and the smart home terminal 103 to transmit user service data, and the remote management device 101 uses a TR069 channel to remotely manage the home gateway 102.
Home gateways, wireless routers, internet of things terminals and the like have the possibility of being attacked and controlled by hackers, so that the risk of revealing user information is faced. A hacker will typically modify or delete the remote management channel between the home gateway and the remote management device. At present, telecom operators cannot solve the safety infection risk of the home gateway through remote recovery configuration, software upgrading and the like, and only can maintain the home gateway, so that the solving efficiency of the safety infection risk is low.
In order to solve the above problems, the present application provides a remote recovery method and apparatus for a home gateway. The remote recovery method comprises the following steps: the first home gateway determines that communication with the remote management device fails, acquires an IP address of the second home gateway, and sends a first connection request to the IP address of the second home gateway. The second home gateway forwards the first connection request to the remote management device. The remote management device determines that communication with the first home gateway fails, and sends a first operation instruction to the second home gateway. And the second home gateway forwards the first operation instruction to the first home gateway. And the first home gateway determines that the first operation instruction carries the identifier of the first home gateway, executes the configuration operation of the fallback source according to the configuration information of the first channel, and then sends a second connection request to the remote management device. And the remote management equipment sends a connection response to the first home gateway and determines that the remote recovery of the first home gateway is successful. The method provides another remote repairing mode for the first home gateway, and can improve the repairing efficiency of the home gateway security infection risk.
The remote recovery method for the home gateway provided by the embodiment of the application is suitable for the intelligent home network system shown in fig. 1. The remote management device and the home gateway in fig. 1 both belong to a remote recovery apparatus of the home gateway. In a specific implementation, the remote recovery apparatus of the home gateway has the components shown in fig. 2. Fig. 2 is a remote recovery apparatus for a home gateway according to an embodiment of the present application, and the apparatus may include a processor 202, where the processor 202 is configured to execute an application code, so as to implement a remote recovery method for a home gateway in the present application.

The memory 203 may be a separate device connected to the processor 202 via a bus. The memory 203 may also be integrated with the processor 202.
As shown in fig. 2, the remote recovery apparatus of the home gateway may further comprise a communication interface 201, wherein the communication interface 201, the processor 202 and the memory 203 may be coupled to each other, for example, via a bus 204. The communication interface 201 is used for information interaction with other devices, for example, information interaction between a remote recovery apparatus supporting a home gateway and other devices.
It is noted that the equipment structure shown in fig. 2 does not constitute a limitation of the remote recovery means of the home gateway, and that the remote recovery means of the home gateway may comprise more or less components than those shown in fig. 2, or combine some components, or a different arrangement of components than those shown in fig. 2.
The following describes, with reference to fig. 3 and fig. 4, a remote recovery method for a home gateway provided in an embodiment of the present application with reference to an intelligent home network system shown in fig. 1 and a remote recovery apparatus for a home gateway shown in fig. 2.
Fig. 3 is a schematic flowchart of a remote recovery method for a home gateway according to an embodiment of the present application. Referring to fig. 3, the remote recovery method of the home gateway includes the following steps.
301. The first home gateway determines that communication with the remote management device fails, acquires an IP address of the second home gateway, and sends a first connection request to the IP address of the second home gateway.
The second home gateway is any one home gateway which is positioned in the same IP address field with the first home gateway. The first connection request is for requesting connection to the remote management apparatus. The first connection request carries an identifier of the first home gateway.
First, the first home gateway determines that communication with the remote management device has failed. Specifically, after the first home gateway is deployed in the home of the user, the first home gateway uses its own identifier as a password according to an initial configuration, and periodically connects the remote management device (for example, the TR069 channel of the first home gateway) through the first channel between the first home gateway and the remote management device. For example, the identification of the first home gateway may place a Media Access Control (MAC) address for the first home gateway. When the first home gateway cannot be connected to the remote management device N consecutive times, it is determined that communication with the remote management device has failed. For example, the first home gateway cannot connect to the remote management device for 5 consecutive times, determining that the communication has failed. At this time, when the first home gateway determines that the first home gateway is possible to be hijacked illegally, a remote recovery mechanism is started.
Then, the first home gateway acquires the IP address of the second home gateway. Specifically, the remote management device needs to maintain an information table, where the information table includes the IP addresses of the home gateways that are accessed to the remote management device and located in the same IP address field. And the remote management equipment issues the information table to each home gateway accessed to the remote management equipment and automatically updates the information table at regular intervals. Thus, the first home gateway can determine the IP address of the second home gateway from the information table.
Optionally, the first home gateway uses, as the second home gateway, the second IP address closest to the first IP address of the first home gateway according to the IP address in the information table.
And finally, the first home gateway sends a first connection request to the IP address of the second home gateway to request to connect the remote management equipment. Specifically, the first home gateway sends the first connection request to the IP address of the second home gateway using the internet channel, where the format of the first connection request packet needs to be maintained as a packet format adapted to the TR069 channel.
Optionally, when the first home gateway receives the error message returned by the second home gateway, the next home gateway is reselected from the information table, and the first connection request is sent to the next home gateway.
302. The second home gateway forwards the first connection request to the remote management device.
Optionally, after receiving the first connection request sent by the first gateway, the second home gateway checks whether the remote management channel between itself and the remote management device can be connected normally. If the connection can be normally carried out, the second home gateway replies to the first home gateway correctly; and if the connection cannot be normally carried out, the second home gateway replies an error to the first home gateway so that the first home gateway can select the next home gateway in the information table in time and forward the first connection request.
Specifically, the second home gateway forwards the first connection request to the remote management device using its own TR069 channel. Wherein the second home gateway's own TR069 channel, i.e. the remote management channel between the second home gateway and the remote management device.
303. The remote management device determines that communication with the first home gateway fails, and sends a first operation instruction to the second home gateway.
The first operation instruction is used for instructing the first home gateway to execute a return source configuration operation, namely a factory reset operation. The first operation instruction carries an identifier of the first home gateway.
Specifically, after receiving a first connection request sent by a second home gateway, the remote management device determines, through an identifier of the first home gateway in the first connection request, that the first connection request does not belong to the second home gateway, and then determines, by the remote management device, that the second home gateway is a proxy gateway. At this time, the remote management device initiates a reverse connection request to the first home gateway, and if the reverse connection is successful, the remote management device determines that the communication with the first home gateway is normal and the first home gateway is not hijacked illegally. If the reverse connection fails, the remote management device determines that the first home gateway is hijacked illegally, starts a remote recovery mechanism, and sends a first operation instruction to the second home gateway.
Further specifically, if the remote management device receives a reverse connection response from the first home gateway, it is determined that the reverse connection is successful. And if the remote management equipment cannot be connected to the first home gateway for M times continuously, determining that the reverse connection fails.
304. And the second home gateway forwards the first operation instruction to the first home gateway.
Specifically, after receiving the first operation instruction, the second home gateway determines that the first operation instruction points to the first home gateway according to the identifier of the first home gateway in the first operation instruction, and forwards the first operation instruction to the first home gateway through the internet channel.
305. And the first home gateway determines that the first operation instruction carries the identifier of the first home gateway, executes a return source configuration operation according to the configuration information of the first channel, and sends a second connection request to the remote management device.
The first channel is a remote management channel between the first home gateway and the remote management device. The second connection request is for requesting connection to the remote management device. Specifically, after the first home gateway quits the source configuration, that is, after factory settings are restored, the first home gateway sends a second connection request to the remote management device through its own TR069 channel (first channel).
306. The remote management device sends a connection response to the first home gateway.
Specifically, when the remote management device receives the second connection request sent by the first home gateway, the remote management device sends a connection response to the first home gateway. At this time, the remote management device determines that the remote recovery of the first home gateway is successful, and closes the remote recovery mechanism.
Further specifically, when receiving the connection response sent by the remote management device, the first home gateway determines that the remote recovery is successful, and closes the remote recovery mechanism.
Further, when the first home gateway performs step 305, the second connection request is sent K times continuously, but the connection response returned by the remote management device is not received all the time, the first home gateway determines that the remote recovery has failed. At this time, the remote recovery method for the home gateway in the present application further includes the steps shown in fig. 4. Referring to fig. 4, the remote recovery method of the home gateway further includes the following steps.
401. And the first home gateway determines the communication failure again and sends an active upgrading request to the second home gateway.
The active upgrading request carries an identifier of the first home gateway, and is used for requesting a software upgrading package of the first home gateway.
Specifically, the first home gateway sends an active upgrade request to the second home gateway through the internet channel. The format of the active upgrade request message needs to be maintained as a message format adapted to the TR069 channel.
402. And the second home gateway forwards the active upgrading request to the remote management equipment.
Specifically, the second home gateway forwards the active upgrade request to the remote management device through a TR069 channel.
403. And the remote management equipment determines that the active upgrading request carries the identifier of the first home gateway and sends a software upgrading packet to the second home gateway.
Specifically, after receiving an active upgrade request sent by a second home gateway, the remote management device determines that the active upgrade request does not belong to the second home gateway through an identifier of a first home gateway in the active upgrade request, and then determines that the second home gateway is a proxy gateway. At this time, the remote management device transmits the software upgrade package of the first home gateway to the second home gateway.
404. And the second home gateway replies a download completion response to the remote management equipment, receives a second operation instruction sent by the remote management equipment and forwards the second operation instruction to the first home gateway.
Specifically, after receiving the software upgrade package sent by the remote management device, the second home gateway replies a download completion response to the remote management device. And after receiving the downloading completion response, the remote management equipment sends a second operation instruction to the second home gateway. The second operation instruction carries the identifier of the first home gateway.
