Description

Method and device for recovering connection of pipe-disconnecting equipment, computer equipment and readable medium
Technical Field
The disclosure relates to the technical field of communication, in particular to a method and a device for recovering connection of off-pipe equipment, computer equipment and a readable medium.
Background
With the rapid development of the internet, the home network is continuously changing to digitalization and intellectualization, which changes the life and entertainment mode of people, and the CPE (Customer Premise Equipment), such as a home gateway, a network access terminal, a wireless routing device, etc., has also become an indispensable component element in the life of people as a key device in the home network. In order to bring a richer and more reliable experience to the user, it is increasingly important for the operator to manage the CPE through the remote management server.
Taking the home gateway as an example, in an actual use process of the home gateway, due to reasons such as a user configuration error, a malicious attack on the home gateway, or an misoperation of an operator of the remote management server, the home gateway may not be connected to the remote management server because the remote management configuration parameters are modified, so that the home gateway is out of management. After the home gateway is taken off line, the remote management server cannot be reversely connected to the home gateway, and cannot control and manage the home gateway through a remote management protocol, so that the management channel is interrupted. The interruption of the management channel does not affect the normal operation of other services such as voice, internet surfing, video and the like temporarily, but the long-time offline of the home gateway can affect the use and the update of the home gateway, so that the home gateway breaks down. Once the out-of-management condition occurs, the operation and maintenance personnel are often dispatched to the user to debug in the house to remove the out-of-management state only after the user fails and reports the repair, so that the user experience and the service quality are seriously influenced, and the labor cost is high.

The embodiment of the invention provides a method for recovering the connection of offline equipment, and the system architecture of the embodiment of the invention is shown in figure 1, wherein the system comprises a remote management server and a plurality of CPEs (customer premises equipment), and the CPEs and the remote management server are communicated based on a TR069 protocol. The system is in a Network environment based on an IP (Internet Protocol) Address, different CPE are in the same IP Address Network segment, and the remote management server can be in the same Address Network segment as the CPE or in another Address Network segment with NAT (Network Address Translation). No matter which address network segment the remote management server is in, the technical scheme of the embodiment of the invention is not affected, and for convenience of introduction, the embodiment of the invention takes the example that the remote management server is in the same network segment with the IP address of the CPE as an example for description. The CPE can request the remote management configuration parameters from other CPEs, realize the remote management configuration parameter sharing among the CPEs, and locally store the backed-up remote management configuration parameters. The CPE can be a home gateway, a network access terminal, wireless routing equipment and the like; the remote management server can issue remote management configuration parameters and a public key to each CPE, authenticate the CPE and encrypt and transmit the remote management configuration parameters with the CPE.
As shown in fig. 2, the method for recovering a connection of a pipe-dropping device according to an embodiment of the present invention is applied to a first CPE, and includes the following steps:
step 11, acquiring remote management configuration parameters in a state of being out of management with a remote management server, wherein the remote management configuration parameters are acquired from the local under the condition that the remote management configuration parameters have backup locally; and under the condition that the remote management configuration parameters do not have backup locally, broadcasting a remote management configuration parameter acquisition request, and receiving the remote management configuration parameters sent by the second CPE.
In this step, the first CPE monitors a connection state between the first CPE and the remote management server, and if it is determined that the first CPE is in an offline state, locally acquires a remote management configuration parameter of the backup, and if the remote management configuration parameter of the backup is not acquired, which indicates that the remote management configuration parameter does not locally have the backup, requests the other CPEs to share the remote management configuration parameter by broadcasting a remote management configuration parameter acquisition request. The remote management configuration parameters are sent by other CPEs (e.g., the second CPE) after receiving the remote management configuration parameter acquisition request and determining that the connection between the other CPEs (i.e., the second CPE) and the remote management server is normal. That is, after receiving the remote management configuration parameter acquisition request broadcast by the first CPE, the second CPE detects a connection state between itself and the remote management server, and if the connection is normal, sends its own remote management configuration parameter to the first CPE. If the first CPE acquires the remote management configuration parameters of the backup, which indicates that the remote management configuration parameters have a backup locally, the first CPE directly configures the remote configuration parameters of the backup locally.
It should be noted that the remote management configuration parameters to be backed up are the remote management configuration parameters applied when the first CPE successfully establishes a connection with the remote management server last time. And for the case that the first CPE is successfully connected with the remote management server for the first time, the backed-up remote management configuration parameters are the remote management configuration parameters applied when the first CPE is successfully connected with the remote management server for the first time.
In some embodiments, the remote management configuration request carries port information of the reverse port, so that the second CPE shares the remote configuration parameters through the reverse port.
And step 12, establishing connection with a remote management server according to the remote management configuration parameters.
In this step, under the condition that the remote management configuration parameter does not have a backup locally, the first CPE monitors the reverse port, and if the remote configuration parameter sent by another CPE (i.e., the second CPE) is received at the reverse port, the first CPE locally configures and restarts the remote configuration parameter to reestablish the management channel, after the first CPE is restarted, the connection with the remote management server is established through the newly established management channel, and the first CPE is in the offline state.
Under the condition that the remote management configuration parameters have backup locally, the first CPE directly configures the backup remote configuration parameters locally and restarts the backup remote configuration parameters to reestablish the management channel, after the first CPE is restarted, the connection with the remote management server is established through the newly established management channel, and the offline state of the first CPE is released.
The method for recovering the connection of the pipe-removing equipment provided by the embodiment of the invention is applied to the CPE of the first customer premise equipment and comprises the following steps: acquiring remote management configuration parameters under the state of being out of management with a remote management server; establishing connection with the remote management server according to the remote management configuration parameters; wherein, the obtaining of the remote management configuration parameter includes: under the condition that the remote management configuration parameters have local backup, the remote management configuration parameters are obtained from the local; and under the condition that the remote management configuration parameters do not have backup locally, broadcasting a remote management configuration parameter acquisition request, and receiving the remote management configuration parameters sent by the second CPE. According to the embodiment of the invention, the connection state of the CPE and the management server is monitored, the remote management configuration parameters are obtained from other CPE under the condition that the CPE is in the offline state and the remote management configuration parameters are not backed up locally, the connection with the remote management server is recovered based on the remote management configuration parameters, and the backed-up remote management configuration parameters are obtained locally under the condition that the CPE is in the offline state and the remote management configuration parameters are backed up locally, so that the CPE is independent of a management channel, the offline state is automatically and quickly removed under the condition that a user does not sense the remote management server, the reliability is improved, the user experience is improved, and the operation and maintenance cost is reduced.
Since the transmitted remote management configuration parameters are not encrypted, there is still a possibility of interception and tampering, and moreover, whether the identity of the second CPE providing the remote management configuration parameters is legal or not is unknown, so there is also a certain risk that the first CPE in the offline state directly applies the remote management configuration parameters sent by the second CPE to take effect.
To solve the above technical problem, in some embodiments, the remote management configuration parameters may be encrypted and transmitted between the CPEs and the remote management server and between the CPEs. Accordingly, in some embodiments, the receiving the remote management configuration parameters sent by the second CPE may include: and receiving the encrypted remote management configuration parameters sent by the second CPE. In this step, the second CPE obtains the remote management configuration parameter from the remote management server, and the remote management server encrypts the correct remote management configuration parameter by using the private key, returns the encrypted remote management configuration parameter to the second CPE, and sends the encrypted remote management configuration parameter to the first CPE by the second CPE. The private key is held by the remote management server; the public key is held by the CPE and is issued by the remote management server when the CPE is registered to the remote management server. Therefore, the remote management server sends the remote management configuration parameters encrypted by the private key, which not only protects the remote management configuration parameters, but also indicates that the second CPE device obtaining the remote management configuration parameters from the remote management server is a device legally registered on the remote management server, thereby verifying the legal identity of the second CPE device and further ensuring the security and reliability of the data source.
Accordingly, in some embodiments, after receiving the encrypted remote management configuration parameters sent by the second CPE, the method further comprises decrypting the encrypted remote management configuration parameters. In this step, the first CPE decrypts the encrypted remote management configuration parameters using the pre-stored public key. Because the data encrypted by the private key can only be correctly decrypted by the public key, if the first CPE can correctly decrypt and obtain the remote management configuration parameters, the data source of the remote management configuration parameters is reliable, and the data transmission is reliable.
In some embodiments, the decrypting the encrypted remote management configuration parameters comprises: and decrypting the encrypted remote management configuration parameters under the condition that the encrypted remote management configuration parameters sent by the second CPE are received within a preset time period from the broadcast of the remote management configuration parameter acquisition request. That is to say, when the first CPE broadcasts the remote management configuration parameter acquisition request, it starts to start the timer and monitors the reverse port, and if the encrypted remote management configuration parameter sent by the second CPE is received within the duration of the timer, the timer is closed, and the encrypted remote management configuration parameter is decrypted by using the pre-stored public key. It should be noted that, when the encrypted remote management configuration parameter sent by the second CPE is not received within the preset time period from the broadcast of the remote management configuration parameter obtaining request, the first CPE broadcasts the remote management configuration parameter obtaining request again. That is to say, if the first CPE does not receive the encrypted remote management configuration parameter sent by the second CPE within the duration of the timer, the request for obtaining the remote management configuration parameter is initiated again, that is, the request for obtaining the remote management configuration parameter is broadcast. As known to those skilled in the art, in the case that the remote management configuration parameter sent by the second CPE is not received within the preset time period from the broadcast of the remote management configuration parameter obtaining request, the first CPE also broadcasts the remote management configuration parameter obtaining request again.
After the first CPE is out of management, the connection between the first CPE and the remote management server can be quickly restored by using the backup remote management configuration parameters, so that the first CPE is out of management and self-restored. It should be noted that, if the connection between the remote management server and the remote management configuration parameter that is backed up still cannot be successfully established, the method for recovering the connection of the offline device may further include the following steps: and broadcasting a remote management configuration parameter acquisition request, and establishing connection with a remote management server according to the received remote management configuration parameters under the condition of receiving the remote management configuration parameters sent by the second CPE. That is, if the first CPE failed to take-off self-recovery (i.e., the first CPE still failed to connect to the management server), remote management configuration parameters may be requested from a second CPE of the same network segment to recover from the take-off status.
In some embodiments, the state of out-of-management from the remote management server includes: the number of connection failures with the remote management server is greater than or equal to a preset threshold.
In some embodiments, as shown in fig. 3, after establishing a connection with a remote management server (i.e., step 12), the method for recovering the connection of the offline device further includes the following steps: step 13, under the condition that the remote management configuration parameters of the backup do not exist locally, storing the remote management configuration parameters as the remote management configuration parameters of the backup locally; and under the condition that the remote management configuration parameters of the backup locally exist, updating the remote management configuration parameters of the backup according to the remote management configuration parameters. In this step, after the first CPE restarts and reestablishes a connection with the remote management server, the remote management configuration parameter used for successfully establishing a connection with the remote management server at present is used as a backup remote management configuration parameter, so as to be used as a basis for subsequent offline connection recovery. If the first CPE does not locally store the remote management configuration parameters of the backup, directly storing the remote management configuration parameters as the backup; and if the first CPE locally stores the backup remote management configuration parameters, updating the backup remote management configuration parameters.
An embodiment of the present invention further provides a method for recovering connection of a pipe-disconnecting device, where the method is applied to a second CPE, and as shown in fig. 4, the method for recovering connection of a pipe-disconnecting device includes the following steps:
step 21, receiving a remote management configuration parameter acquisition request broadcasted by the first CPE.
And step 22, sending the remote management configuration parameters to the first CPE under the condition that the connection state with the remote management server is normal.
In this step, the second CPE detects a connection state of the second CPE to the remote management server, and transmits remote management configuration parameters of the second CPE to the first CPE when the connection state to the remote management server is normal.
Since the second CPE cannot know whether the first CPE broadcasting the remote management configuration parameter acquisition request is a legitimate CPE, there is a risk that the second CPE directly transmits its own remote management configuration parameter to the first CPE. In order to solve the above technical problem, in some embodiments, the first CPE may carry first CPE identity information in the remote management configuration parameter acquisition request, so that the remote management server performs identity authentication on the first CPE.
Accordingly, as shown in fig. 5, in some embodiments, after receiving the request for obtaining the remote management configuration parameters broadcast by the first CPE (i.e., step 21), the method further includes the following steps:
step 31, obtaining the identity information of the first CPE from the remote management configuration parameter obtaining request, and sending the identity information of the first CPE to the remote management server.
In this step, if the second CPE receives the remote management configuration parameter acquisition request broadcast by the first CPE and acquires the identity information of the first CPE from the remote management configuration parameter acquisition request, the identity information of the first CPE is sent to the remote management server, and the remote management server verifies the validity of the identity of the first CPE. The identity information of the first CPE includes, but is not limited to: OUI (organization unique identifier), SerialNumber (serial number), ProductClass (product category), and MAC (Mandatory Access Control) address, etc.
In some embodiments, after the second CPE acquires the identity information of the first CPE from the remote management configuration parameter acquisition request, a connection state with the remote management server is detected, and in a case where the connection state with the remote management server is normal, the identity information of the first CPE is sent to the remote management server. The second CPE detects the connection state with the remote management server before requesting the remote management server to verify the identity of the first CPE, and sends the identity information of the first CPE to the remote management server when the second CPE confirms that the second CPE is normally connected with the remote management server, so that the problem that network resources are occupied when data are sent under the condition that the network connection state is poor can be avoided.
And step 32, receiving the result of passing the authentication sent by the remote management server.
And the remote management server verifies the identity information of the first CPE, and if the first CPE is confirmed to be the equipment which is successfully registered according to the identity information of the first CPE and the identity of the first CPE is legal, the result that the identity verification is passed is returned to the second CPE. After receiving the result of passing the authentication, the second CPE (i.e., the CPE receiving the remote management configuration parameter obtaining request) sends its own remote management configuration parameters to the first CPE.
It should be noted that, if the second CPE sends the identity information of the first CPE to the remote management server in step 31, but does not receive the result that the authentication passed or the result that the authentication failed, which is sent by the remote management server, indicates that the connection state between the second CPE and the remote management server is not normal, the second CPE does not send its own remote management configuration parameters to the first CPE any more.
If the remote management server confirms that the first CPE is unregistered equipment according to the identity information of the first CPE, indicating that the identity of the first CPE is illegal, the remote management server returns a result that the identity authentication is not passed to the second CPE, and accordingly, the second CPE does not respond to the remote management configuration parameter acquisition request any more, that is, does not send the own remote management configuration parameters to the first CPE.
The identity legitimacy of the first CPE is verified by using the remote management server, and the second CPE informs the second CPE of the own remote management configuration parameters under the condition that the identity of the first CPE is confirmed to be legal, so that the risk that the CPE is attacked maliciously can be reduced, and the safety and the reliability are improved.
In some embodiments, the result of passing the authentication passes carries the encrypted remote management configuration parameters, that is, if the remote management server passes the authentication of the identity information of the first CPE, the remote management server encrypts the correct remote management configuration parameters by using the private key, and carries the encrypted remote management configuration parameters in the result of passing the authentication and sends the result to the second CPE. Accordingly, the second CPE transmits the remote management configuration parameters encrypted by the remote management server to the first CPE.
In some embodiments, the second CPE sends the remote management configuration parameters encrypted by the remote management server to the first CPE. That is to say, if the second CPE receives the remote management configuration parameter acquisition request broadcast by the first CPE and the remote management configuration parameter acquisition request does not carry the identity information of the first CPE, the remote management configuration parameter acquisition request is directly forwarded to the remote management server, the remote management server does not verify the identity of the first CPE any more, the correct remote management configuration parameter is directly encrypted, the encrypted remote management configuration parameter is returned to the second CPE, and the encrypted remote management configuration parameter is sent to the first CPE by the second CPE.
The embodiment of the invention provides a method for recovering the connection of offline equipment, which relates to a TR069 protocol in the field of communication, namely a CPE WAN (Wide Area Network) management protocol, and is suitable for communication between CPE and an Auto-Configuration Server (ACS). The CPE WAN management protocol is used to implement secure auto-configuration of CPEs and other CPE management functions under a common framework.
The method for recovering the connection of the offline device, provided by the embodiment of the invention, preferentially recovers the configuration of the remote management configuration parameters successfully connected with the remote management server last time, if the remote management server cannot be connected, the first CPE tries to acquire correct remote management configuration parameters from other CPEs in the management domain in a broadcast message mode, so that the connection with the remote management server is recovered. First CPE can try to get rid of the takeoff state automatically after the takeoff, makes CPE can resume automatically under the condition that the user does not have the perception, has improved the resistance to the abnormal conditions, reduces CPE fault rate, promotes user experience, and effectively reduces the fortune dimension cost.
For the purpose of clearly illustrating the solution of the embodiment of the present invention, the following detailed description is made with reference to 4 specific examples, wherein, the CPE takes a home gateway as an example for illustration.
Fig. 6 is a schematic diagram illustrating a connection recovery process of an offline device according to a specific example, where when a first home gateway succeeds in connecting to a remote management server after a gateway is started, a local backup is performed to store current remote management configuration parameters, and a connection state between the first home gateway and the remote management server is monitored at regular time.
