[0022] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0023] Figure 1 FIG. 2 shows a block diagram of a disaster recovery system for a core network device provided in a related embodiment. Figure 1 As shown, the first core network device 111 and the second core network device 112 are core network devices that carry the same type of services, wherein the first core network device 111 is connected to n base stations (such as the first base station 121, the second base station 122, ..., the nth base station 12n), n represents the number of base stations, and n is an integer greater than or equal to 1; at the same time, the second core network device 112 is also connected to the above-mentioned n base stations.

[0024] At the same time, each base station will select the primary core network device among the first core network device 111 and the second core network device 112 as the target device for access.

[0025] Among them, the first core network device 111 and the second core network device 112 send heartbeat detection messages to each other, realize the negotiation process of the main device and the backup device, and determine whether the opposite core network device fails based on the detection of the heartbeat message. When it is determined that the opposite core network device has sent a fault, the main and backup switching is performed.

[0026] However, the above detection method usually requires multiple detection cycles to confirm the link status and whether the core network device on the other end has a fault, which increases the network delay between the two core network devices. The faulty core network device cannot be maintained and repaired in time, which will cause certain network fluctuations and cannot meet the reliability requirements of the communication network. Especially for industrial production industries with high network delay accuracy, it reduces the communication efficiency between devices.

[0027] The present application provides a disaster recovery method, system, electronic device and storage medium for core network equipment to solve the above problems.

[0028] Figure 2 A schematic diagram of a process flow of a disaster recovery method for a core network device provided in an embodiment of the present application is shown. The disaster recovery method for the core network device can be applied to a first abnormal disaster recovery device. Figure 2 As shown, the disaster recovery method of the core network equipment in the embodiment of the present application includes but is not limited to the following steps.

[0029] Step S201: receiving an abnormality signal sent by a second abnormality disaster recovery device.

[0030] The abnormal signal is used to indicate that a fault occurs in the second core network device, and the second abnormal disaster recovery device is used to perform abnormality detection on the second core network device.

[0031] Step S202: convert the abnormal signal into a signal that can be recognized by the core network device.

[0032] For example, when the abnormal signal is a power-off signal, the power-off signal may be converted into a converted abnormal signal recognizable by the first core network device, such as a binary symbol (eg, using a binary symbol "1" to represent a power-off signal).

[0033] For another example, when the abnormal signal represents the degree of change in the amplitude of voltage or current, the abnormal signal can be converted into an identifier that can be recognized by the core network device (for example, the identifier of normal operation of the second core network device is pre-set as "M", and the identifier of abnormal operation is pre-set as "N"). When the abnormal signal is received, it is converted into the identifier "N", so that the first core network device can quickly and accurately know whether the first core network device has an abnormality.

[0034] Step S203: Send the converted abnormal signal to the first core network device.

[0035] Among them, the first core network device and the second core network device are in a master-slave relationship with each other, and the first core network device determines whether to change the master-slave state of the first core network device based on the converted abnormal signal and the master-slave state information of the first core network device.

[0036] In this embodiment, by receiving an abnormal signal sent by the second abnormal disaster recovery device, the abnormal signal is used to indicate that a fault has occurred in the second core network device, and the second abnormal disaster recovery device is used to perform abnormal detection on the second core network device, so as to accurately and timely know whether an abnormality has occurred in the second core network device; then, the first abnormal disaster recovery device converts the abnormal signal into a signal that can be recognized by the core network device, which is conducive to the first core network device to respond to the abnormal signal in a timely manner; the converted abnormal signal is sent to the first core network device, and the first core network device and the second core network device are in a master-slave relationship with each other. The first core network device determines whether to change the master-slave state of the first core network device based on the converted abnormal signal and the current master-slave state information of the first core network device. There is no need for the first core network device and the second core network device to exchange messages multiple times, and the working status of the opposite core network device can be accurately known, thereby improving the reliability of detection and reducing the network delay generated during fault detection.

[0037] Figure 3 A schematic diagram of a process flow of a disaster recovery method for a core network device provided in an embodiment of the present application is shown. The disaster recovery method for a core network device can be applied to a first core network device. Figure 3 As shown, the disaster recovery method of the core network equipment in the embodiment of the present application includes but is not limited to the following steps.

[0038] Step S301: receiving a converted abnormal signal sent by a first abnormal disaster recovery device.

[0039] The converted abnormal signal is a signal obtained by converting the abnormal signal, and the abnormal signal is used to indicate that a fault occurs in the second core network device; the second core network device and the first core network device are in a master-standby relationship with each other.

[0040] Step S302: Determine whether to change the active / standby state of the first core network device according to the converted abnormal signal and the current active / standby state information of the first core network device.

[0041] In this embodiment, by analyzing the converted abnormal signal received from the first abnormal disaster recovery device, it is determined that the second core network device has a fault. Without the need for multiple message interactions between the first core network device and the second core network device, the working status of the second core network device can be accurately known, thereby improving the reliability of detection and reducing the network delay generated during the fault detection process. Furthermore, based on the converted abnormal signal and the current active-standby status information of the first core network device, it is determined whether to change the active-standby status of the first core network device, so as to clarify which core network device is used as the active device, reduce network fluctuations, meet the reliability requirements of the communication network, and improve the communication efficiency between various devices in the communication network.

[0042] In some exemplary embodiments, determining whether to change the active / standby state of the first core network device according to the converted abnormal signal and the active / standby state information of the first core network device in step S302 may be implemented in the following manner:

[0043] When it is determined that the first core network device is currently in a standby state, the first core network device is switched from the standby state to the active state; when it is determined that the first core network device is currently in the active state, the active and standby states of the first core network device are kept unchanged.

[0044] By using the first core network device in the standby state as the main core network device, it can be ensured that when the second core network device fails, the communication network can still work normally, thereby ensuring the stability of the communication network. When it is determined that the first core network device is currently in the main state, a converted abnormal signal indicating that the second core network device has failed is received, indicating that the second core network device as the backup has failed. At this time, the main and standby states of the first core network device can be kept unchanged, thereby ensuring the normal operation of the communication network.

[0045] At the same time, the first core network equipment can also promptly remind the operation and maintenance personnel (such as by issuing an alarm message, etc.) to repair the second core network equipment to ensure that the second core network equipment can be repaired in time, which is conducive to the stable operation of the subsequent communication network.

[0046] In some exemplary embodiments, after the first core network device is switched from a standby state to an active state, the method further includes: sending a core network device change notification message to a network element device that is communicatively connected to the second core network device.

[0047] The core network device change notification message is used to indicate that the first core network device is used to replace the second core network device to provide communication services for the network element device. For example, the core network device change notification message includes the identifier of the first core network device and the active / standby status of the first core network device.

[0048] By sending a core network device change notification message to the network element device (for example, a base station, etc.) that is communicatively connected to the second core network device, each network element device can be informed that the first core network device will provide it with communication services, and the relevant configuration information (for example, the identification of the core network device, the port number of the core network device, etc.) of each network element device in the message interacting with the core network device can be changed in a timely manner, thereby reducing the occurrence of abnormalities such as communication failures caused by changes in the core network device and improving communication stability.

[0049] In some exemplary embodiments, after determining whether to change the active-standby state of the first core network device based on the converted abnormal signal and the current active-standby state information of the first core network device in step S302, the method further includes: generating abnormal alarm information of the core network device, and sending the abnormal alarm information of the core network device to the management device.

[0050] The abnormal alarm information of the core network device includes the core network device identification; the management device is used to repair the second core network device and / or the first core network device.

[0051] The management device can quickly locate which core network device has an abnormality based on the core network device identifier in the received core network device abnormality alarm information, and accurately repair the abnormal core network device, so that the abnormal core network device can quickly return to normal operation and ensure the stability of the communication network.

[0052] Figure 4 A flow chart of a disaster recovery method for a core network device provided by an embodiment of the present application is shown. The disaster recovery method for the core network device can be applied to a second abnormal disaster recovery device, which can be arranged inside or outside the second core network device.

[0053] like Figure 4 As shown, the disaster recovery method of the core network equipment in the embodiment of the present application includes but is not limited to the following steps.

[0054] Step S401: Detect the second core network device to obtain a detection signal.

[0055] Among them, the detection signal is used to characterize the real-time working status of the second core network device. Through the detection signal, it can be determined whether the second core network device has an abnormality and whether the abnormality affects the normal operation of the second core network device.

[0056] Step S402: Determine whether a fault occurs in the second core network device based on the detection signal.

[0057] If the second core network device fails, execute step S403; otherwise, end the process.

[0058] Step S403: Send an abnormality signal to the first abnormality disaster recovery device.

[0059] The abnormal signal is used to indicate that a fault occurs in the second core network device.

[0060] When the second abnormal disaster recovery device is arranged inside the second core network device, and the second abnormal disaster recovery device 821 determines through a detection signal that the second core network device has a fault (for example, the operating voltage of the second core network device is lower than 85% of the preset voltage threshold), a capacitor device arranged inside the second core network device can be used to accumulate a portion of electricity through charging and discharging, and an abnormal signal generated based on the detection signal can be sent to the first abnormal disaster recovery device.

[0061] For example, the capacitor device is charged when the second core network device is working normally; when it is determined that the second core network device has a fault, the capacitor device can be enabled as a backup power supply for the faulty second core network device, and its stored electricity can be used to send an abnormal signal, so that the first abnormal disaster recovery device can promptly receive the abnormal signal used to characterize the failure of the second core network device, and promptly inform the first core network device, so that the first core network device can quickly take response measures (such as replacing the second core network device to provide communication services for other network element devices in the communication network, etc.), thereby ensuring the stability of the communication network.

[0062] In this embodiment, a detection signal is obtained by detecting the second core network device, so that it is clear through the detection signal whether the second core network device has an abnormality and whether the abnormality affects the normal operation of the second core network device. There is no need to frequently send heartbeat detection messages to the second core network device through the first core network device, thereby reducing the message interaction between the two core network devices; whether the second core network device has a fault is determined according to the detection signal. When the second core network device has a fault, an abnormal signal is sent to the first abnormal disaster recovery device, so that the first abnormal disaster recovery device can transmit the information that the second core network device has a fault to the first core network device through the abnormal signal, and then the first core network device replaces the second core network device through the master-slave switching to continue to provide communication services for the network element devices in the communication network, thereby reducing the possibility of network paralysis and improving the reliability of the communication network.

[0063] In some exemplary embodiments, where the detection signal is an operating voltage signal of the second core network device, determining whether the second core network device is faulty based on the detection signal in step S402 can be implemented in the following manner: determining whether the operating voltage signal of the second core network device is within a preset voltage range; if the operating voltage signal of the second core network device is within the preset voltage range, determining that the second core network device is not faulty; if the operating voltage signal of the second core network device is not within the preset voltage range, determining that the second core network device is faulty.

[0064] Among them, the preset voltage range includes at least one preset voltage threshold (for example, 85% of the working voltage of the second core network device is set as the preset voltage threshold). When the working voltage of the second core network device is lower than 85% of its working voltage, it can be determined that the working voltage signal of the second core network device is not within the preset voltage range. At this time, it is determined that the second core network device has a fault. It can accurately measure whether the second core network device has a fault, thereby improving the efficiency of fault locating.

[0065] In some embodiments, the preset voltage range may be set between a first preset voltage threshold and a second preset voltage threshold, wherein the first preset voltage threshold is smaller than the second preset voltage threshold.

[0066] For example, the working voltage of the second core network device is set to A, and the preset voltage range is 80%A~99%A. When the working voltage corresponding to the working voltage signal of the second core network device obtained by detection is within 80%A~99%A, it indicates that the second core network device has no faults; when the working voltage corresponding to the working voltage signal of the second core network device obtained by detection is not within 80%A~99%A, it indicates that the second core network device has failed and needs to be repaired in time.

[0067] By adopting the above-mentioned judgment method to determine whether the second core network device has a fault, the fault status of the second core network can be judged quickly and accurately, thereby improving the efficiency of fault locating.

[0068] In some exemplary embodiments, where the detection signal is a working current signal of the second core network device, determining whether the second core network device has a fault based on the detection signal in step S402 can be implemented in the following manner: determining whether the working current signal of the second core network device is within a preset current range; if the working current signal of the second core network device is within the preset current range, determining that the second core network device has not a fault; if the working current signal of the second core network device is not within the preset current range, determining that the second core network device has a fault.

[0069] Among them, the preset current range includes at least one preset current threshold (for example, 70% of the working current of the second core network device is set as the preset current threshold). When the working current of the second core network device is lower than 70% of its working current, it can be determined that the working current signal of the second core network device is not within the preset current range. At this time, it is determined that the second core network device has a fault. It can accurately measure whether the second core network device has a fault, thereby improving the fault location efficiency.

[0070] In some embodiments, the preset current range may be set between a first preset current threshold and a second preset current threshold, wherein the first preset current threshold is smaller than the second preset current threshold.

[0071] For example, the working current of the second core network device is set to B, and the preset current range is 70%*B~99%*B. When the working current corresponding to the working current signal of the second core network device obtained by detection is within 70%*B~99%*B, it indicates that the second core network device has no faults; when the working current corresponding to the working current signal of the second core network device obtained by detection is not within 70%*B~99%*B, it indicates that the second core network device has failed and needs to be repaired in time.

[0072] By adopting the above-mentioned judgment method to determine whether the second core network device has a fault, the fault status of the second core network can be judged quickly and accurately, thereby improving the efficiency of fault locating.

[0096] The first core network device 810 and the second core network device 820 are in a master-slave relationship with each other; the first abnormal disaster recovery device 811 is used to execute the disaster recovery method of the core network device applied to the first abnormal disaster recovery device; the second abnormal disaster recovery device 821 is used to execute the disaster recovery method of the core network device applied to the second abnormal disaster recovery device; the first core network device 810 is used to execute the disaster recovery method of the core network device applied to the first core network device.

[0097] In some exemplary embodiments, the first abnormal disaster recovery device 811 is connected to the first core network device 810; and the second abnormal disaster recovery device 821 is connected to the second core network device 820. For example, the first abnormal disaster recovery device 811 is arranged outside the first core network device 810, and it can detect whether the first core network device 810 has an abnormality by means of a network cable or a wireless connection.

[0098] Similarly, the second abnormal disaster recovery device 821 is also arranged outside the second core network device 820, and can detect whether there is an abnormality in the second core network device 820 through a network cable or a wireless connection.

[0099] For example, the first abnormal disaster recovery device 811 executes the following method: receiving an abnormal signal sent by the second abnormal disaster recovery device 821; wherein the abnormal signal is used to indicate that the second core network device 820 has a fault, and the second abnormal disaster recovery device 821 is used to perform abnormality detection on the second core network device 820; converting the abnormal signal into a signal that can be recognized by the core network device; sending the converted abnormal signal to the first core network device 810; the first core network device 810 determines whether to change the master-slave state of the first core network device 810 based on the converted abnormal signal and the current master-slave state information of the first core network device 810.

[0100] For another example, the first core network device 810 executes the following method: receiving a converted abnormal signal sent by the first abnormal disaster recovery device 811; wherein the converted abnormal signal is a signal obtained by converting the abnormal signal, and the abnormal signal is used to indicate that the second core network device 820 has a fault; based on the converted abnormal signal and the current active-standby status information of the first core network device 810, determining whether to change the active-standby status of the first core network device 810.

[0101] For another example, the second abnormal disaster recovery device 821 executes the following method: detect the second core network device 820 to obtain a detection signal; determine whether the second core network device 820 has a fault based on the detection signal; when the second core network device 820 has a fault, send an abnormal signal to the first abnormal disaster recovery device 811; wherein the abnormal signal is used to indicate that the second core network device 820 has a fault.

[0102] In some embodiments, if the second abnormal disaster recovery device 821 is arranged inside the second core network device 820, when the second abnormal disaster recovery device 821 determines through a detection signal that the second core network device 820 has a fault (for example, the operating voltage of the second core network device 820 is lower than 85% of the preset voltage threshold), it can be achieved by using a capacitor device arranged inside the second core network device 820 to accumulate a portion of electricity through charging and discharging, and send an abnormal signal generated based on the detection signal to the first abnormal disaster recovery device 811.

[0103] When the first abnormal disaster recovery device 811 detects that there is an abnormality in the first core network device 810 (for example, the first core network device 810 loses power, or the voltage of the first core network device 810 is not within a preset voltage range, etc.), the first abnormal disaster recovery device 811 will send an abnormal signal to the second abnormal disaster recovery device 821, and then the second abnormal disaster recovery device 821 will convert the abnormal signal into a signal that can be recognized by the core network device, and then send the converted abnormal signal to the second core network device 820.

[0104] When the second core network device 820 receives the converted abnormal signal, if the current active-standby state of the second core network device 820 is the standby state, it will change the standby state to the active state to replace the first core network device 810 to continue to provide communication services for other network element devices, thereby realizing rapid detection of abnormalities and state switching between the active and standby core network devices, reducing the disaster recovery switching delay, and improving the reliability of the core network disaster recovery system.

[0105] Fig. 9 The following is a schematic diagram showing the information interaction process of each device in a disaster recovery system of a core network device provided by an embodiment of the present application. Fig. 9 As shown, the method for information interaction between various devices in the disaster recovery system of the core network device in the embodiment of the present application includes but is not limited to the following steps.

[0106] Step S901 , initializing the active / standby state of the first core network device 810 and the active / standby state of the second core network device 820 .

[0107] Among them, the active and standby states of the first core network device 810 can be determined to be active and the active and standby states of the second core network device 820 can be determined to be standby by means of heartbeat detection; the active and standby states of the first core network device 810 and the active and standby states of the second core network device 820 can also be determined according to pre-configuration information. This application does not limit this, and other unspecified methods for initializing the active and standby states of the core network devices are also within the protection scope of this application and will not be described in detail here.

[0108] Step S902 , connecting the communication unit of the first abnormal disaster recovery device 811 and the second abnormal disaster recovery device 821 .

[0109] In step S903, a communication connection is established between the base station 830 and the first core network device 810, and it is determined that the active / standby state of the first core network device 810 is the active state.

[0110] The communication connection between the base station 830 and the first core network device 810 may be a connection via an S1 interface or an N2 interface.

[0111] In step S904, a communication connection is established between the base station 830 and the second core network device 820, and it is clarified that the active / standby state of the second core network device 820 is the standby state.

[0112] The communication connection between the base station 830 and the second core network device 820 may also be a connection via an S1 interface or an N2 interface.

[0113] Step S905: the first abnormal disaster recovery device 811 detects the first core network device 810 to obtain a detection signal.

[0114] The detection signal indicates whether the working current signal of the first core network device 810 is within a preset current range, and / or indicates whether the working voltage signal of the first core network device 810 is within a preset voltage range.

[0115] For example, when the detection signal indicates that the operating voltage of the first core network device 810 is lower than 85% of the rated voltage, it is determined that the first core network device 810 is faulty and cannot operate normally, and step S906 needs to be executed.

[0116] It should be noted that the first abnormal disaster recovery device 811 can be set inside the first core network device 810, and can also be set outside the first core network device 810, and is communicatively connected to the first core network device 810.

[0117] Step S906 , when it is determined that the detection signal indicates that the first core network device 810 has a fault, the first abnormal disaster recovery device 811 sends an abnormal signal to the second abnormal disaster recovery device 821 .

[0118] The abnormal signal is used to indicate that a fault occurs in the second core network device.

[0119] Step S907 : the second abnormality disaster recovery device 821 performs signal conversion on the received abnormality signal to obtain the converted abnormality signal that can be recognized by the second core network device 820 .

[0120] For example, when the abnormal signal is a power-off signal, the power-off signal may be converted into a binary symbol recognizable by the second core network device 820 (eg, using a binary symbol "1" to represent a power-off signal).

[0121] Step S908 : The second abnormal disaster recovery device 821 sends the converted abnormal signal to the second core network device 820 .

[0122] Step S909, when the second core network device 820 receives the converted abnormal signal, based on the current active-standby state information of the second core network device 820 and the converted abnormal signal, the second core network device 820 determines to change its active-standby state to the active state.

[0123] Since the active-standby state of the second core network device 820 is the standby state when executing step S901 initialization, and at this time, according to the converted abnormal signal, it can be known that the first core network device 810 has a fault, therefore, the second core network device 820 converts its active-standby state to the active state.

[0124] Step S910 , the second core network device 820 sends a core network device change notification message to the base station 830 .

[0125] Among them, the core network device change notification message is used to represent the use of the second core network device 820 to replace the first core network device 810 to provide communication services for the base station 830.

[0126] In some embodiments, while executing step S910, the second core network device 820 also generates core network device abnormality alarm information; and sends the core network device abnormality alarm information to a management device (not shown in the figure).

[0127] The core network device abnormal alarm information includes a core network device identifier (eg, a device identifier of the first core network device 810 ), and the management device is used to repair the first core network device 810 .

[0128] When the second core network device 820 works as the main core network device, the second abnormal disaster recovery device 821 also executes step S911 to detect the second core network device 820 in real time to determine whether the second core network device 820 fails.

[0129] Step S911: the second abnormal disaster recovery device 821 detects the second core network device 820 to obtain a detection signal.

[0130] For example, the detection signal indicates that the operating current signal of the second core network device 820 is not within the preset current range, such as the operating current is lower than 80% of the rated current, etc. It can be determined that the second core network device 820 has a fault and generates an abnormal signal.

[0131] Step S912 : The second abnormal disaster recovery device 821 sends an abnormal signal to the first abnormal disaster recovery device 811 .

[0132] Step S913: the first abnormality disaster recovery device 811 performs signal conversion on the received detection signal to obtain a converted abnormality signal.

[0133] Step S914 : the first abnormal disaster recovery device 811 sends the converted abnormal signal to the first core network device 810 .

[0134] It should be noted that the first core network device 810 can return to normal working status after being repaired by the management device; however, during the period when the second core network device 820 does not fail, the master-slave status of the first core network device 810 will be set to the standby status.

[0135] Step S915, after receiving the converted abnormal signal, the first core network device 810 determines to change its active-standby state to the active state based on the current active-standby state information (i.e., standby state) of the first core network device 810 and the converted abnormal signal.

[0136] Similarly, the first core network device 810 will also send a core network device change notification message to the base station 830 , and the core network device change notification message is used to indicate that the first core network device 810 is used to replace the second core network device 820 to provide communication services for the base station 830 .

[0137] In this embodiment, an abnormal disaster recovery device (e.g., the first abnormal disaster recovery device 811) detects the core network device corresponding to it (e.g., the first core network device 810) to obtain a detection signal, so that it is clear through the detection signal whether the core network device has an abnormality and whether the abnormality affects the normal operation of the core network device. There is no need to frequently send heartbeat detection messages from the first core network device 810 to the second core network device 820, thereby reducing the message interaction between the two core network devices; then, it is determined whether the first core network device 810 has a fault based on the detection signal. In the event that the first core network device 810 has a fault, the first abnormal disaster recovery device 811 sends a heartbeat detection message to the second abnormal disaster recovery device 820. 821 sends an abnormal signal so that the second abnormal disaster recovery device 821 can transmit the information that the first core network device 810 has failed to the second core network device 820 through the abnormal signal, and then the second core network device 820 replaces the first core network device 810 through the master-slave switching method to continue to provide communication services for the network element devices in the communication network, thereby reducing the possibility of network paralysis and improving the reliability of the communication network. Similarly, the second abnormal disaster recovery device 821 will also detect the second core network device 820 in order to timely know the working status of the second core network device 820, so that each core network device can work normally, and provide stable and reliable communication services for each network element device in the communication network.
