[0034] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0036] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0037] To address the problem of users being unable to use the network when a leased network line fails, this application provides a method, apparatus, device, and medium for handling leased network line failures. This method can be applied to scenarios where an existing leased network line fails, preventing users from accessing the internet or communicating via that line. The method primarily utilizes Software Defined Wide Area Network (SD-WAN) technology to provide users with access to cloud resources and unified management of the wide area network. It deploys the network in a more economical, simple, and efficient manner, enabling the rapid establishment of a new leased network line based on SDN-WAN technology when the original leased network fails, providing a convenient alternative for users.

[0038] Specifically, this method can establish new network leased lines between user areas by setting up corresponding Customer Premise Equipment (CPE) in the user area and connecting to the network via the SDN controller (SDN) when the original network leased line is interrupted, based on the optical cable interruption information determined by the acquired optical cable testing equipment. In this way, users can quickly establish new network leased lines when the original network leased line fails, thereby solving the problem of users being unable to use the network when the network leased line fails.

[0039] The network leased line fault handling method provided in this application can be executed by a network leased line fault handling device or a control module within the network leased line fault handling device. This application uses the execution of the network leased line fault handling method by the network leased line fault handling device as an example to describe the network leased line fault handling method provided in this application in detail.

[0040] The following description, in conjunction with the accompanying drawings, details the network leased line fault handling method, apparatus, device, and storage medium provided in this application through specific embodiments.

[0041] Figure 1 This is a flowchart illustrating a network leased line fault handling method provided in an embodiment of this application.

[0042] like Figure 1 As shown, the main body executing this network leased line fault handling method is the network leased line fault handling device, which may specifically include the following steps:

[0043] S110: Obtain the optical cable interruption information determined by the optical cable testing equipment.

[0044] The network leased line fault handling device can acquire fiber optic cable interruption information determined by fiber optic cable testing equipment via signal transmission. The fiber optic cable testing equipment is used to test whether the fiber optic cable is interrupted. The fiber optic cable testing equipment can be an optical power meter or an optical time-domain reflectometer (OTDR). The fiber optic cable interruption information is used to characterize whether the first network leased line is interrupted.

[0045] In one embodiment, when the optical cable testing equipment is an optical power meter, the optical power meter determines whether the optical cable is interrupted by testing the continuity of the optical cable. Accordingly, the optical cable interruption information can be indicated by "yes" or "no", or by "1" or "0", where "1" indicates that the optical cable is interrupted and "0" indicates that the optical cable is not interrupted. No further limitations are made here.

[0046] In another embodiment, when the optical cable testing equipment is an OTDR, the OTDR determines whether the optical cable is interrupted by testing the location of the interruption. Accordingly, whether the optical cable is interrupted can be indicated by whether the parsed optical cable interruption information includes specific optical cable interruption location information.

[0047] In another embodiment, when the optical cable testing equipment includes an optical power meter and an OTDR, the optical cable interruption information includes not only whether the optical cable is interrupted, but also the location of the optical cable interruption.

[0048] To give a concrete example, if the PON port of a certain optical modem is red, indicating that the original network leased line is at risk of failure, an optical power meter and an OTDR can be used to test the optical cable in advance. If it is determined that the user's failure to access the Internet is due to the optical cable being interrupted, the optical cable interruption information can be sent to the network leased line fault handling device through signal transmission.

[0049] S120, when the optical cable interruption information indicates that the first network leased line is interrupted, the corresponding first client device CPE and second CPE are set up in the first user area and the second user area respectively.

[0050] The first network leased line is an existing network leased line used for information transmission between multiple user terminals located in a first user area or a second user area and the network, or for information transmission between multiple user terminals located in the first user area and the second user area. The first user area and the second user area each include at least one user terminal, which includes, but is not limited to, communication devices such as mobile phones, computers, and tablets. The first CPE and the second CPE are devices respectively installed in the first user area and the second user area for accessing mobile signals. User terminals included in the first user area and the second user area can access the network through their respective CPE devices to achieve data transmission or internet connection.

[0051] Specifically, when the optical cable interruption information indicates that the first network leased line is interrupted, the corresponding first CPE and second CPE can be set up in the first user area and the second user area respectively through the network leased line fault handling device.

[0052] In one specific embodiment, the network leased line fault handling device sets up corresponding first CPEs and second CPEs in the first user area and the second user area, respectively, which may specifically include the following steps:

[0053] Step 1: Connect the CPE device to a communication device, such as a computer, on the same physical network, open a web browser, enter the default IP address of the CPE device, and access the administrator login interface.

[0054] Step 2: After successfully logging into the Web management menu, begin configuring the CPE device. Open Wireless and select the appropriate working mode in Basic Wireless Settings' Wireless Mode, then fill in the relevant parameters according to your needs. For client configuration and remote bridge, select the Station working mode. On the Station side, there is a Select button next to the ESSID; clicking it will search for nearby devices. Select the device you want to connect to.

[0055] In another embodiment, the network leased line fault handling device can also test the first CPE and the second CPE respectively set in the first user area and the second user area to ensure that the set CPE devices can be used normally.

[0056] Therefore, in the event of a failure of the first leased network line, by setting up corresponding CPE devices in the first user area and the second user area respectively, it is not only convenient to establish a new leased network line for users to continue to use, thus improving the user experience, but also easy to deploy and manage.

[0057] S130, the first CPE and the second CPE are connected to the network via the SDN controller to establish a second network leased line between the first user area and the second user area.

[0058] The SDN controller, based on SD-WAN technology, serves as the medium for connecting the first and second CPEs to the network. This network can be either a 4G or 5G network; no specific limitations are specified here. The second leased network line is established to temporarily replace the first leased network line in case of a failure. In other words, the second leased network line serves the same function as the first, facilitating information transmission between multiple user terminals located in the first or second user area and the network, as well as information transmission between multiple user terminals located in the first and second user areas respectively.

[0059] Specifically, after the network leased line fault handling device sets up corresponding CPE devices that can be used to access mobile signals in the first user area and the second user area respectively, the network leased line fault handling device can connect the first CPE and the second CPE corresponding to the first user area and the second user area respectively to the network via the SDN controller to establish a second network leased line between the first user area and the second user area.

[0060] Based on this, the first user area and the second user area can be connected to the network via the second leased network line, thus achieving internet connectivity. Furthermore, the first user area and the second user area can also establish a communication connection via the second leased network line, enabling data transmission between them.

[0061] Therefore, by acquiring the fiber optic cable interruption information determined by the fiber optic cable testing equipment, indicating an interruption of the first network leased line (i.e., a failure of the first network leased line), a second network leased line is established between the first and second user areas by setting up corresponding first and second CPEs respectively in the first and second user areas. The first and second CPEs are then connected to the network via the SDN controller. This allows for the rapid establishment of a second network leased line even when the first network leased line fails, enabling user terminals in both user areas to continue using the network via the second network leased line, thereby improving the user experience.

[0062] To facilitate the rapid establishment of a second network lease, in some embodiments, the above-mentioned S130 may include:

[0063] The first CPE and the second CPE are connected to the network via a wired or wireless connection through the SDN controller to establish a second network leased line between the first user area and the second user area.

[0064] Specifically, in the event of a failure in the first leased network line, the first CPE and the second CPE, corresponding to the first user area and the second user area respectively, can be connected to the network via a wired connection through the SDN controller to establish a second leased network line. Alternatively, the first CPE and the second CPE can be connected to the network via a wireless connection through the SDN controller to establish a second leased network line.

[0065] Based on this, in a specific embodiment, when the first CPE and the second CPE are connected to the network via a wireless connection through an SDN controller, the aforementioned steps of establishing a second network lease between the first user area and the second user area include:

[0066] Based on a first user identification SIM card pre-configured in a first CPE and a second SIM card pre-configured in a second CPE, a second network leased line is established between the first user area and the second user area by connecting to the network via an SDN controller.

[0067] The first user identification SIM card is a SIM card that is pre-set in the first CPE for connecting to the network, and the second SIM card is a SIM card that is pre-set in the second CPE for connecting to the network.

[0068] Specifically, a first SIM card and a second SIM card can be pre-configured in the first CPE and the second CPE, respectively. In the event of a failure in the first network leased line, multiple user terminals in the first user area can directly connect to the network via the SDN controller using the pre-configured first CPE in that user area. Similarly, multiple user terminals in the second user area can connect to the network via the SDN controller using the pre-configured second SIM card in the second user area, and user terminals in both areas can communicate based on their respective connected networks. This establishes a second network leased line between the first and second user areas wirelessly.

[0069] For example, as shown in Figure 2, suppose the first user area is a hospital, and the second user area is an outpatient clinic within that hospital. The hospital and the outpatient clinic connect to the internet and communicate via their respective optical modems and OLT (Optical Line Terminal) devices. If the existing leased network line connecting the network via the optical modem and OLT fails, CPE (Content Premises Equipment) devices, such as SD-CPE devices, can be installed in both the first and second user areas. This allows the existing leased network line to be spliced ​​to the SD-CPE device, which then connects to a base station and further to a VCPE (Virtual Cable Premises Equipment). VCPEs can include proprietary networks, private networks, and third-party networks. In this way, user terminals can connect to the 4G or 5G network via the SD-CPE device in their respective user area, through a 4G or 5G base station and via an SDN controller, thereby enabling the rapid establishment of a new leased network line wirelessly.

[0070] Based on this, in some embodiments, since the user terminals in the first user area and the second user area access each other through an SD-CPE device and a connected VCPE, the success of their mutual access can be verified by testing. The specific testing process is as follows:

[0071] Configure the overlay network (Layer 2 VXLAN) for SD-CPE and vCPE: SD-CPE and vCPE are ready and the manufacturer has completed the configuration.

[0072] Configure the vCPE DHCP address pool to assign addresses in the same network segment to user terminals connected to the SD-CPE. For example, the IP address of the first user area is 192.168.1.100, and the IP address of the second user area is 192.168.1.101. The configuration is successful.

[0073] Two user terminals connected to two SD-CPEs can send bidirectional traffic to each other.

[0074] Alternatively, verification can be performed through on-site testing. Specifically, the LAN1 port of the SD-WAN is connected to the optical modem via a network cable, allowing the PON uplink CPE device to access the metropolitan area network. The PTN line is the original leased network line's port 11 of the switch; for SD-WAN line testing, the network cable on the switch's port 11 needs to be switched to the LAN2 port of the SD-CPE.

[0075] By deploying SD-CPEs under the optical modems in the first and second user areas, and verifying the ping test results between the user terminals at both ends, it was found that branch offices can access each other via SD-CPE and vCPE. This solution can provide a channel for devices requiring branch-to-branch communication, demonstrating the feasibility of an emergency rapid restoration solution based on SD-WAN data leased lines. Therefore, the feasibility of establishing a network leased line using wireless connections can be quickly verified.

[0076] In another specific embodiment, where the first CPE and the second CPE are connected to the network via a wired connection through an SDN controller, the steps described above for establishing a second network lease between the first user area and the second user area include:

[0077] Based on the transmission networks of the first user area and the second user area respectively, a second network leased line is established between the first user area and the second user area via the SDN controller network, connecting the first CPE and the second CPE respectively.

[0078] The transmission network consists of optical modem equipment, OLT equipment, and broadband access server (BARS), and is used to connect the network lines.

[0079] Specifically, the network leased line fault handling device will connect the first CPE to the network through the transmission network used to connect the network in the first user area, and the network leased line fault handling device will also connect the second CPE to the network through the transmission network used to connect the network in the second user area, thereby establishing a second network leased line between the first user area and the second user area.

[0080] For example, such as Figure 3 As shown, when it is determined that the original mobile PTN network between the first user area and the second user area has failed, SD-CPE devices can be temporarily set up in both user areas. In the first user area, the logical connection between the corresponding SD-CPE device and the SDN controller, and the physical connection between the SD-CPE device and the optical modem, OLT device, metropolitan area network, and VCPE, enables a wired connection to the network in the event of a failure of the original leased network line. The connection method for the second user area is the same as that for the first user area, and will not be described further here. In this way, users can switch the user services carried by the failed original first leased network line to the newly built second leased network line, thereby quickly restoring the internet and data leased lines, allowing users to continue to access the internet or communicate normally, thus improving the user experience.

[0081] In another embodiment, the network leased line fault handling method further includes:

[0082] When the fiber optic cable interruption information indicates that the first network leased line is interrupted, a third network leased line is established based on the SIM card pre-configured in the router in the user area. The third network leased line is used for information transmission between multiple user terminals in the user area and the Internet.

[0083] Specifically, in the event of a failure in the original leased network line of a single user area, the leased network line failure handling device can establish a third leased network line by connecting to the network via the SIM card in the router of the user area where the network leased line failed. This network can be a 4G or 5G network, and the third leased network line is used for information transmission between multiple user terminals within the user area and the Internet.

[0084] For example, suppose the access fiber optic cable in a user area is interrupted, making it impossible to quickly restore user services in that area within a short period of time. Figure 4 As shown, if the customer's local area network used in the user area fails, a router temporarily set up in the user area can be used to establish communication with the existing base station based on its own SIM card, thereby connecting to the network and accessing the network.

[0085] In some embodiments, the network leased line fault handling device can deploy a router in the user area through pre-operation and set up the relevant SIM card in the router. The specific router deployment process is as follows:

[0086] Step 1: SIM card region locking needs to be performed on the 4G router.

[0087] Step 2: Set the Wi-Fi name and Wi-Fi key.

[0088] Step 3: After setting up, restart the router and test whether the 4G router can be used normally.

[0089] Step 4: Connect the customer's terminal device to the 4G router to restore the relevant services.

[0090] In addition, the router can be tested as follows:

[0091] Connect your computer to the 4G router's Wi-Fi signal or connect it via wired connection, and perform a long-term ping test on the configured IP address. If you can successfully ping the configured IP address without packet loss, the test is successful, and the emergency communication link based on the 4G router's internet leased line is successfully established, that is, the third network leased line is successfully established.

[0092] Furthermore, in some embodiments, when the faulty first network leased line is restored to normal, the user services carried by the second network leased line can be switched back to the original first network leased line, which will not be elaborated further here.

[0093] Therefore, in the event of a failure of the first leased network line, a SIM card can be pre-installed in the router within a single user area. The router containing the SIM card can then connect to the network via a base station. This effectively enables users to continue using the network and achieve internet connectivity by establishing a new leased network line when the original leased network line in the user area fails.

[0094] Based on the same inventive concept, this application also provides a network leased line fault handling device. Specifically, in conjunction with... Figure 5 Explanation

[0095] Figure 5 This is a schematic diagram of the structure of a network leased line fault handling device provided in an embodiment of this application.

[0096] like Figure 5 As shown, the network leased line fault handling device may include: an acquisition module 510, a setting module 520, and an establishment module 530.

[0097] The acquisition module 510 is used to acquire optical cable interruption information determined by the optical cable testing equipment;

[0098] Setting module 520 is used to set up corresponding first client device CPE and second CPE in the first user area and the second user area respectively when the optical cable interruption information indicates that the first network leased line is interrupted.

[0099] The module 530 is used to connect the first CPE and the second CPE to the network via the SDN controller to establish a second network leased line between the first user area and the second user area. The second network leased line is used for information transmission between multiple user terminals in the first user area or the second user area and the network, as well as for information transmission between multiple user terminals in the first user area and the second user area.

[0100] In an optional embodiment, the establishment module is specifically used to: connect the first CPE and the second CPE to the network via the SDN controller through a wired connection or a wireless connection, respectively, to establish a second network leased line between the first user area and the second user area.

[0101] In an optional embodiment, where the first CPE and the second CPE are connected to the network via the SDN controller through a wireless connection, the establishment module is further specifically configured to: connect the first CPE and the second CPE to the network via the SDN controller based on the first user identification SIM card pre-set in the first CPE and the second SIM card pre-set in the second CPE, respectively, to establish a second network leased line between the first user area and the second user area.

[0102] In an optional embodiment, where the first CPE and the second CPE are connected to the network via a wired connection through the SDN controller, the establishment module is further specifically used for:

[0103] Based on the transmission networks of the first user area and the second user area respectively, the first CPE and the second CPE are connected via the SDN controller network to establish a second network leased line between the first user area and the second user area.

[0104] In an optional embodiment, the establishment module is further configured to establish a third network leased line based on a SIM card pre-configured in a router in the user area when the optical cable interruption information indicates that the first network leased line is interrupted. The third network leased line is used for information transmission between multiple user terminals included in the user area and the Internet.

[0105] In an optional embodiment, the optical cable testing equipment includes an optical power meter and / or an optical timing reflector (OTDR).

[0106] This application embodiment characterizes the interruption of the first network leased line by acquiring optical cable interruption information determined by optical cable testing equipment. Specifically, in the event of a failure of the first network leased line, a second network leased line is established between the first and second user areas by setting up corresponding first and second CPEs in the first and second user areas respectively. The first and second CPEs are then connected to the network via an SDN controller. This enables the rapid establishment of a second network leased line in the event of a first network leased line failure, allowing user terminals in both user areas to continue using the network via the second network leased line, thereby improving the user experience.

[0107] The various modules in the network leased line fault handling device provided in this application embodiment can achieve... Figure 1 The method steps of the illustrated embodiment, and the corresponding technical effects they achieve, will not be described in detail here for the sake of brevity.

[0108] Figure 6 This is a schematic diagram of the structure of a network leased line fault handling device provided in an embodiment of this application.

[0109] like Figure 6 As shown, the network leased line fault handling device 600 in this embodiment includes an input device 601, an input interface 602, a central processing unit 603, a memory 604, an output interface 605, and an output device 606. The input interface 602, central processing unit 603, memory 604, and output interface 605 are interconnected via a bus 610. The input device 601 and output device 606 are connected to the bus 610 via the input interface 602 and output interface 605, respectively, and are subsequently connected to other components of the network leased line fault handling device 600.

[0110] Specifically, input device 601 receives input information from the outside and transmits the input information to central processing unit 603 through input interface 602; central processing unit 603 processes the input information based on computer-executable instructions stored in memory 604 to generate output information, temporarily or permanently stores the output information in memory 604, and then transmits the output information to output device 606 through output interface 605; output device 606 outputs the output information to the outside of network leased line fault handling device 600 for user use.
