Abstract

The invention provides a base station fault processing method, a base station and a computer readable storage medium. The method comprises the following steps: a sub-base station in a base station group determines a self fault and / or a main base station fault according to a first condition that the sub-base station receives a message from the base station group, that is, the current sub-base station cannot complete a corresponding function of a sub-machine mode, so that the sub-base station switches a working mode of the sub-base station from the sub-machine mode to a single-station mode, and the sub-base station does not complete the corresponding function of the sub-machine mode. And the sub-base station continues to provide service for the terminal equipment in the single-station mode. Therefore, after the sub-base station determines that the sub-base station cannot complete the corresponding function of the sub-machine mode, the sub-base station automatically switches the working mode into the single-station mode and can continue to provide services for the terminal equipment, so that the disaster recovery capability is improved and the maintenance cost is reduced.

When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] In the present disclosure, "at least one" refers to one or more, and "plurality" refers to two or more.

"At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a alone, b alone, or c alone can represent: a alone, b alone, c alone, a and b in combination, a and c in combination, b and c in combination, or a, b, and c in combination, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0061] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present disclosure and simplifying the description.

[0062] The terms "connected" and "connected" should be understood in a broad sense. For example, the "connected" or "connected" of a circuit structure may refer to not only a physical connection, but also an electrical connection or a signal connection. For example, it may be a direct connection, i.e. a physical connection, or it may be an indirect connection through at least one intermediate element, as long as the circuit is connected. It may also be the internal connection of two elements. In addition to signal connection through a circuit, signal connection may also refer to signal connection through a media medium, such as radio waves. For those of ordinary skill in the art, the specific meanings of the above terms in this disclosure may be understood according to specific circumstances.

[0063] Combining multiple base stations into a base station group can solve problems such as co-channel interference and can be applied to the field of autonomous driving where terminal devices move in the coverage area of ​​multiple base stations. A base station group includes multiple base stations, one of which is the main base station and the other base stations are sub-base stations. Figure 1 A base station group is introduced by way of example.

[0064] See also Figure 1 , Figure 1 A schematic diagram of the structure of a base station group provided in an embodiment of the present disclosure. Figure 1 As shown, the base station group of the present application may include: a main base station 11 and two or more sub-base stations. Figure 1FIG. 2 exemplarily shows two sub-base stations, namely sub-base station 12 and sub-base station 13. Figure 1 As shown in the figure, the main base station 11, the sub-base station 12 and the sub-base station 13 can be connected to the switch 14 respectively, and the switch 14 is connected to the core network device. In addition, the sub-base station 12 and the sub-base station 13 can also be connected to the core network device through the main base station 11 respectively. The main base station 11, the sub-base station 12 and the sub-base station 13 can be connected to the terminal device. In the base station group, the sub-base station 12 and the sub-base station 13 interact with the core network device through the main base station 11 respectively, and provide services for the terminal devices connected thereto respectively. For example, after the sub-base station 12 establishes a connection with the terminal device, the uplink data sent by the terminal device to the sub-base station 12 is sent to the core network device through the main base station 11. The core network device sends the downlink data to the first sub-base station 12 through the main base station 11, and the first sub-base station 12 sends the downlink data to the terminal device.

[0065] Among them, the main base station 11, the sub-base station 12 and the sub-base station 13 can be a base station (base transceiver station, BTS) in global system of mobile communication (GSM) or code division multiple access (CDMA), or a base station (NodeB, NB) in wideband code division multiple access (WCDMA), or an evolved base station (eNB or eNodeB) in long term evolution (LTE), or a terminal or relay station or access point that performs the base station function in V2X (vehicular to everything), device-to-device (D2D), and machine-to-machine (M2M) communications, or a base station in a 5G network, such as gNB, etc., or a base station in a future 6G network, which is not limited here.

[0066] Terminal equipment: may refer to user equipment, access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user device. The terminal device may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device or a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a terminal device in a 5G network, a terminal device in a 6G network, or a terminal device in a future communication network, etc. In addition, the terminal device may also be a terminal device in an Internet of Things (IoT) system.

[0067] The working mode of the main base station is the host mode. The host mode means that as a main base station, it manages the sub-base stations in the base station group. The uplink data of the sub-base station needs to be converted by the main base station and then sent to the core network equipment. The downlink data sent by the core network equipment needs to be converted by the main base station and then sent to the sub-base station. The working mode of the sub-base station is the slave mode. The slave mode means that as a sub-base station, after establishing a connection with the main base station, it works under the management of the main base station, receives / sends uplink and downlink data through the main base station, and thus provides services for terminal devices.

[0068] For a base station group, in a possible implementation, a main base station and sub-base stations may be determined before networking. The main base station is connected to each sub-base station for communication, and each sub-base station can provide services for terminal devices.

[0069] In another possible implementation, a base station group may send messages by multicast. The base station group may predetermine a main base station and a sub-base station, and the base station group may also send messages by multicast to exchange data and implement a self-organizing network.

[0070] Exemplarily, a fixed version of a sub-machine program may be burned into the sub-base station so that the sub-base station can work in the sub-machine mode.

[0071] However, when a sub-base station fails, the sub-base station cannot work normally, and accordingly, the sub-base station cannot provide services to terminal devices, making the disaster recovery capability of the base station group poor. When a sub-base station fails, manual troubleshooting is usually required. Only after the fault is eliminated can the sub-base station resume service, which results in high maintenance costs.

[0072] The present disclosure provides a method for processing base station failure, a base station and a computer-readable storage medium. In a base station group, after determining that the sub-base station fails and / or the main base station fails, that is, the sub-base station itself cannot complete the corresponding functions of the sub-machine mode, the sub-base station switches the working mode from the sub-machine mode to the single-station mode, wherein the sub-machine mode refers to a working mode in which data is exchanged with a core network device through the main base station, and the single-station mode refers to a working mode in which data is not exchanged with a core network device through the main base station. Therefore, after the sub-base station determines that it cannot complete the corresponding functions of the sub-machine mode, it automatically and quickly switches the working mode to the single-station mode, and can continue to provide services for the terminal device, thereby improving the disaster recovery capability and reducing the maintenance cost.

[0073] The technical solution and beneficial effects of the present invention are described in detail below with reference to specific embodiments.

[0074] See also Figure 2 , Figure 2 The following is a flow chart of a method for processing a base station failure provided by an embodiment of the present disclosure. Figure 2 As shown, the method provided in this embodiment can be applied in a base station group, the base station group includes a main base station and at least one sub-base station, and the base station group can be the above-mentioned Figure 1 The method provided in this embodiment is performed by a sub-base station, which can be any sub-base station in the base station group, and can be, for example, the above-mentioned Figure 1 Any sub-base station in the illustrated embodiment may be, for example, sub-base station 12 or sub-base station 13. The method provided in this embodiment may include the following steps 201 and 202.

[0075] Step 201: Determine, according to a first situation of receiving a message from a base station group, whether a sub-base station is faulty and / or a main base station is faulty.

[0076] The first case of receiving a message from the base station group may be the first case of receiving a message from a main base station in the base station group, or the first case of receiving a message from other base stations in the base station group.

[0077] The sub-base station failure means that the sub-base station is abnormal and cannot complete the corresponding functions of the slave mode. The main base station failure means that the main base station is abnormal and cannot complete the corresponding functions of the host mode, so the sub-base stations connected to it cannot complete the corresponding functions of the slave mode.

[0078] Generally, if the sub-base station works normally in the slave mode, it can receive messages from the base station group. Exemplarily, the first case of receiving a message from the base station group may refer to not receiving a message sent from the base station group. If no message is received from the base station group in the recent period of time, it can be considered that the sub-base station itself is faulty and / or the main base station is faulty.

[0079] Step 202: Switch the working mode from slave mode to single station mode.

[0080] Among them, the slave mode refers to a working mode in which data is exchanged with the core network equipment through the main base station, and the single-station mode refers to a working mode in which data is not exchanged with the core network equipment through the main base station.

[0081] In this embodiment, the sub-base station in the base station group determines that it is faulty and / or the main base station is faulty according to the first situation of receiving a message from the base station group, that is, the current sub-base station cannot complete the corresponding functions of the sub-machine mode, so the sub-base station switches its own working mode from the sub-machine mode to the single-station mode, and the sub-base station continues to provide services for the terminal device in the single-station mode. Therefore, after the sub-base station determines that it cannot complete the corresponding functions of the sub-machine mode, it automatically switches the working mode to the single-station mode, and can continue to provide services for the terminal device, thereby improving the disaster recovery capability and reducing the maintenance cost.

[0082] In some embodiments, the sub-base station fault may be determined in various ways in step 201. Three ways of determining the sub-base station fault are described below.

[0083] For a possible implementation, see Figure 3 , Figure 3 A flowchart of another method for processing a base station failure provided by an embodiment of the present disclosure is provided. Figure 3 The embodiment shown is in Figure 2 On the basis of the illustrated embodiment, further, step 201 may include the following step 301 .

[0084] Step 301: If a first message sent by a main base station is not received within a first preset time period, it is determined that the sub-base station is faulty and / or the main base station is faulty.

[0085] Among them, the first message refers to any message sent when the main base station and the sub-base station interact with each other. For example, the first message can be a configuration message or a management message sent between the main base station and the sub-base station. After the main base station establishes a connection with the sub-base station, it sends a configuration message to the sub-base station to configure the connection, etc. During the working process, the main base station will also periodically send a management message to the sub-base station, and the management message can also be a heartbeat message sent by the main base station.

[0086] The first preset duration is greater than the maximum time between the primary base station sending adjacent first messages. Generally, considering network delays and other conditions, in order to avoid frequent switching of the sub-base station, the first preset duration can be set longer based on the maximum time between the primary base station sending adjacent first messages.

[0087] In this embodiment, data is usually exchanged between the main base station and the sub-base station. Therefore, if the sub-base station does not receive the first message sent by the main base station within the first preset time, it can be determined that the sub-base station itself is faulty and / or the main base station is faulty. The sub-base station does not receive the message from the main base station for a long time, so that it can determine that it cannot complete the corresponding functions of the sub-machine mode, and automatically switches the working mode to the single-station mode, so that it can continue to provide services for the terminal equipment, thereby improving the disaster recovery capability and reducing the maintenance cost.

[0088] Further, step 301 can be implemented in the following manner:

[0089] If the first message sent by the main base station is not received within the first preset time period, a confirmation message is sent to the main base station.

[0090] If no reply message sent by the main base station is received within a sixth preset time period after the confirmation message is sent, it is determined that the sub-base station is faulty and / or the main base station is faulty.

[0091] In this embodiment, when the sub-base station has not received any message from the main base station for a long time and has not received any reply to the confirmation message sent to the main base station, it is determined that the sub-base station has failed and / or the main base station has failed, and the working mode is automatically switched to the single-station mode, so that services can continue to be provided to the terminal equipment, thereby improving disaster recovery capabilities and reducing maintenance costs.

[0092] For another possible implementation, see Figure 4 , Figure 4 A flowchart of another method for processing a base station failure provided by an embodiment of the present disclosure is provided. Figure 4 The embodiment shown is in Figure 2 On the basis of the illustrated embodiment, further, step 201 may include the following steps 201a and 201b.

[0093] Step 201a: Periodically receive a heartbeat message sent by the primary base station.

[0094] In this embodiment, the main base station periodically sends a heartbeat message to the sub-base station, that is, the main base station sends a host heartbeat message to the sub-base station at periodic intervals.

[0095] In one possible implementation, during operation, the main base station establishes a communication connection with each sub-base station respectively. The main base station periodically sends heartbeat messages to the sub-base stations through the communication connection, so that all sub-base stations in the base station group can periodically receive the heartbeat messages sent by the main base station.

[0096] In another possible implementation, the base station group is a multicast group. Therefore, all base stations in the base station group can send messages by multicast. The main base station can periodically multicast heartbeat messages to the base station group, so that all sub-base stations in the base station group can periodically receive heartbeat messages sent by the main base station.

[0097] Furthermore, the heartbeat message may include device information of the primary base station. Exemplarily, the device information of the primary base station may include at least one of the following: an Internet Protocol (IP) address of the primary base station, an identity document (ID) of the primary base station, and a serial number (SN code) of the primary base station.

[0098] Step 201b: If no heartbeat message sent by the master base station is received within the second preset time period, it is determined that the sub-base station is faulty and / or the master base station is faulty.

[0099] The second preset duration is greater than or equal to a cycle time, and the cycle time refers to a cycle time during which the master base station periodically sends a heartbeat message to the sub-base station.

[0100] In this embodiment, if the sub-base station does not receive a heartbeat message sent by the main base station within the second preset time after receiving the most recent heartbeat message sent by the main base station, it can be determined that the sub-base station itself is faulty and / or the main base station is faulty. Among them, in the case where the base station group includes a main base station and a sub-base station, if the sub-base station cannot receive the heartbeat message of the main base station, it may be a sub-base station fault or a main base station fault. Since there is only one sub-base station in the base station group at this time, in order to continue to provide services for the terminal device, the sub-base station can switch the working mode from the sub-machine mode to the single-station mode.

[0101] In the case where the base station group includes a main base station and two or more sub-base stations, if the sub-base station cannot receive the heartbeat message of the main base station, it may be a sub-base station failure or a main base station failure. If it is a sub-base station failure itself, the sub-base station can switch the working mode from sub-machine mode to single-station mode; if it is a main base station failure itself, the sub-base station cannot provide services to the terminal device until the main base station failure is eliminated. In this case, the sub-base station can also switch the working mode from sub-machine mode to single-station mode. In summary, in order to continue to provide services to the terminal device, if the sub-base station does not receive the heartbeat message sent by the main base station within the second preset time after receiving the most recent heartbeat message, the working mode is switched from sub-machine mode to single-station mode.

[0102] In this embodiment, the main base station periodically sends a heartbeat message to the sub-base station. If the sub-base station does not receive the heartbeat message sent by the main base station within the second preset time, it determines that the sub-base station has a fault and / or the main base station has a fault. Thus, by the main base station periodically sending a heartbeat message to the sub-base station, after the heartbeat message received by the sub-base station is lost, it can be determined that the sub-base station has a fault and / or the main base station has a fault. The method for determining the fault is simple and easy to implement. After determining the fault, it can quickly switch to the single-station mode to provide services for the terminal device.

[0103] Furthermore, step 201b may be implemented in the following manner:

[0104] If the heartbeat message sent by the primary base station is not received within the second preset time period, a confirmation message is sent to the primary base station.

[0105] If no reply message sent by the main base station is received within a sixth preset time period after the confirmation message is sent, it is determined that the sub-base station is faulty and / or the main base station is faulty.

[0106] In this embodiment, when the sub-base station has not received the heartbeat message sent by the main base station for a long time and has not responded to the confirmation message sent to the main base station, it determines that the sub-base station has failed and / or the main base station has failed, and automatically switches the working mode to the single-station mode, so that it can continue to provide services to the terminal equipment, thereby improving the disaster recovery capability and reducing the maintenance cost.

[0107] In another possible implementation, see Figure 5 , Figure 5 A flowchart of another method for processing a base station failure provided by an embodiment of the present disclosure is provided. Figure 5 The embodiment shown is in Figure 2 On the basis of the illustrated embodiment, further, step 201 may include the following steps 2011 and 2012.

[0108] Step 2011: Periodically receive heartbeat messages sent by other base stations through multicast.

[0109] The heartbeat message includes device information of other base stations that send the heartbeat message. Other base stations are base stations in the base station group except the sub-base station.

[0110] In this embodiment, the base station group can be a multicast group. Usually, during the operation of the base station group, the main base station establishes a communication connection with each sub-base station respectively, and no communication connection is established between the sub-base stations. The base stations in the base station group can all send messages by multicast. Therefore, the main base station can send a heartbeat message to each sub-base station respectively through the communication connection, and the main base station can also send a heartbeat message by multicast. Each sub-base station can receive the heartbeat message sent by the main base station through the base station group. For a sub-base station, the sub-base station needs to send its own heartbeat message by multicast so that other sub-base stations in the base station group can receive the heartbeat message.

[0111] Exemplarily, when a base station in a base station group sends a heartbeat message, the sub-base station multicasts and sends its own heartbeat message. The main base station can send a heartbeat message in the following two ways. In one possible implementation, the main base station periodically sends a heartbeat message to each sub-base station through a communication connection established with each sub-base station, so that all sub-base stations in the base station group can periodically receive the heartbeat message sent by the main base station.

[0112] In another possible implementation, the master base station may also periodically multicast a heartbeat message to the base station group, so that all the sub-base stations in the base station group can periodically receive the heartbeat message sent by the master base station.

[0113] Furthermore, the heartbeat message sent by any of the above base stations may include device information of the base station that sends the heartbeat message.

[0114] Exemplarily, the device information may include at least one of the following: an IP address, an ID, and a serial number.

[0115] Step 2012: If at least one heartbeat message is not received within a third preset time period, it is determined that the sub-base station is faulty and / or the main base station is faulty.

[0116] Among them, the third preset duration is greater than or equal to the cycle time. The cycle time refers to the cycle time for other base stations to periodically send heartbeat messages to sub-base stations. Among them, if the cycle time for the main base station to periodically send heartbeat messages is different from the cycle time for each sub-base station to periodically send heartbeat messages, then the above cycle time refers to: the larger value of the cycle time for the main base station to periodically send heartbeat messages and the cycle time for each sub-base station to periodically send heartbeat messages.

[0117] In this embodiment, if the sub-base station does not receive a heartbeat message sent by other base stations within the third preset time after receiving the most recent heartbeat message, it can be determined that it is faulty. Among them, in the case where the base station group includes a main base station and a sub-base station, if the sub-base station cannot receive the heartbeat message of the main base station, it may be a sub-base station fault or a main base station fault. Since there is only one sub-base station in the base station group at this time, in order to continue to provide services for the terminal device, the sub-base station can switch the working mode from the sub-machine mode to the single-station mode.

[0118] When the base station group includes a main base station and two or more sub-base stations, if the sub-base station cannot receive the heartbeat message of other base stations, the sub-base station can be considered to have a fault and can switch the working mode from sub-station mode to single-station mode.

[0119] In this embodiment, other base stations in the base station group periodically send heartbeat messages to the sub-base station. If the sub-base station does not receive a heartbeat message sent by any other base station within the third preset time, it is determined that the sub-base station has a fault and / or the main base station has a fault. Thus, by other base stations periodically sending heartbeat messages to the sub-base station, after the heartbeat message received by the sub-base station is lost, it can be determined that the sub-base station has a fault and / or the main base station has a fault. The method for determining the fault is simple and easy to implement. After the fault is determined, it can quickly switch to the single-station mode to provide services for the terminal device.

[0120] Furthermore, step 2012 can be implemented in the following manner:

[0121] If at least one heartbeat message is not received within the third preset time period, a confirmation message is sent to the primary base station.

[0122] If no reply message sent by the main base station is received within a sixth preset time period after the confirmation message is sent, it is determined that the sub-base station is faulty and / or the main base station is faulty.

[0123] In this embodiment, when the sub-base station has not received the heartbeat message sent by other base stations in the base station group for a long time and has not responded to the confirmation message sent to the main base station, it determines that the sub-base station has failed and / or the main base station has failed, and automatically switches the working mode to the single-station mode, so that it can continue to provide services to the terminal equipment, thereby improving the disaster recovery capability and reducing the maintenance cost.

[0124] In some embodiments, step 2011 may be followed by step 2013.

[0125] Step 2013: If at least one heartbeat message is received within the fourth preset time period, and no heartbeat message multicasted by the primary base station is received, it is determined that the primary base station is faulty.

[0126] Among them, the fourth preset duration is greater than or equal to the cycle time, and less than or equal to the third preset duration. The cycle time refers to the cycle time for other base stations to periodically send heartbeat messages to sub-base stations. Among them, if the cycle time for the main base station to periodically send heartbeat messages is different from the cycle time for each sub-base station to periodically send heartbeat messages, then the above cycle time refers to: the larger value of the cycle time for the main base station to periodically send heartbeat messages and the cycle time for each sub-base station to periodically send heartbeat messages.

[0127] In this embodiment, if a sub-base station can receive heartbeat messages sent by other sub-base stations but cannot receive a heartbeat message sent by the main base station, it indicates that a failure occurs in the main base station.

[0128] Furthermore, if the main base station fails, all sub-base stations in the base station group will also be unable to provide services to the terminal device. In one possible implementation, after determining that the main base station has failed, the sub-base station switches the working mode to the single-station mode in order to provide services to the terminal device. In another possible implementation, after determining that the main base station has failed, the sub-base station can redetermine a main base station in the base station group to achieve re-networking and provide services to the terminal device. The following is a detailed description with specific embodiments.

[0129] Furthermore, after step 2013, the following steps 2014 to 2017 may also be included.

[0130] Step 2014: Determine a first master base station from all sub-base stations in the current base station group according to a preset method.

[0131] Among them, all sub-base stations in the base station group are all sub-base stations in the current base station group that can be determined by the sub-base station. It can be understood that usually all sub-base stations in the current base station group that can be determined by the sub-base station are consistent with all sub-base stations in the current base station group. All sub-base stations in the base station group include the first sub-base station. In this embodiment, any sub-base station in the base station group performs the processing of the first sub-base station.

[0132] Step 2015: Determine whether the first sub-base station is the second main base station.

[0133] If yes, continue to step 2016; if no, continue to step 2018.

[0134] Step 2016: Send a host message to the base station group.

[0135] After receiving the host message from the base station group, the other sub-base stations set their working modes to the sub-base station mode.

[0136] Furthermore, the host message includes the device information of the first main base station. Usually in the slave mode, it is necessary to establish a communication connection with the main base station first, so that the first sub-base station in the slave mode establishes a connection with the first main base station according to the device information of the first main base station in the host message.

[0137] Exemplarily, the device information of the first main base station may include at least one of the following: an IP address of the first main base station, an ID of the first main base station, and a serial number of the first main base station.

[0138] Step 2017, switch the working mode to the host mode.

[0139] It should be noted that after the sub-base station determines that it is the first main base station, there is no order for executing step 2016 and step 2017. Step 2016 may be executed first, and then step 2017; step 2017 may be executed first, and then step 2016; and step 2016 and step 2017 may be executed simultaneously. The present disclosure does not limit the execution order of step 2016 and step 2017.

[0140] Step 2018: After receiving the host message sent by the base station group, set the working mode to the slave mode.

[0141] In actual applications, the following processing is performed for each sub-base station in the base station group: after the sub-base station determines that the current main base station in the base station group is faulty, it determines the first main base station, that is, the new main base station, from all the sub-base stations in the base station group according to a preset method. Since all the sub-base stations determine the first main base station according to the same preset method, the first main base station determined by all the sub-base stations in the base station group is the same.

[0142] For each sub-base station, if the sub-base station determines that it is the first main base station, it multicasts a host message to other sub-base stations and switches its own working mode to the host mode. Other sub-base stations determine that they are not the first main base station, wait to receive the host message, and after receiving the host message, set their own working mode to the slave mode.

[0143] The following uses the example of a base station group including a main base station, sub-base station 1, sub-base station 2 and sub-base station 3 to illustrate the interaction process of the base station group after the main base station fails, thereby realizing a self-organizing network. Figure 6 , Figure 6The interactive diagram of a base station networking method provided by an embodiment of the present disclosure. After detecting the failure of the main base station, sub-base station 1, sub-base station 2 and sub-base station 3 all execute the above step 2014, that is, after determining that the main base station in the base station group has failed, a new main base station is determined from all sub-base stations in the current base station group according to a preset method. After sub-base station 1, sub-base station 2 and sub-base station 3 respectively execute step 2013, they respectively execute step 2014. Sub-base station 1, sub-base station 2 and sub-base station 3 respectively determine the first main base station according to the same preset method, and the first main base stations respectively determined by sub-base station 1, sub-base station 2 and sub-base station 3 are the same. It can be understood that any sub-base station in the base station group may be determined as the first main base station according to the preset method. For the convenience of description, this embodiment assumes that sub-base station 1 is determined to be the first main base station. Sub-base station 1 executes the above steps 2016 and 2017, that is, after sub-base station 1 determines that it is the first main base station, it multicasts a host message to the base station group and switches its own working mode to the host mode. After receiving the host message sent by the sub-base station 1 respectively, the sub-base station 2 and the sub-base station 3 execute step 2018, that is, switch the working mode to the slave mode.

[0144] The networking method of the base station provided in this embodiment is that within the base station group, for each sub-base station, after detecting that the current main base station fails, the first main base station is determined from the current sub-base stations according to the same preset method. Since the sub-base stations determine the first main base station according to the same preset method, each sub-base station determines the same first main base station. The sub-base station determined as the first main base station sends a host message to the base station group and switches its own working mode to the host mode. After receiving the host message, the other sub-base stations switch their own working modes to the sub-machine mode. Therefore, after the main base station fails, the base station group automatically and quickly determines a new main base station from the sub-base stations, so that it can continue to provide services for the terminal equipment, thereby improving the disaster recovery capability of the base station group and reducing maintenance costs.

[0145] Furthermore, in a possible implementation of step 2014, it can be implemented through the following steps 20141 to 20143.

[0146] Step 20141: Send a first slave heartbeat message to the base station group.

[0147] The heartbeat message of the first sub-station includes the device information of the sub-base station.

[0148] Exemplarily, the device information of the sub-base station may include at least one of the following: an IP address of the sub-base station, an ID of the sub-base station, and a serial number of the sub-base station.

[0149] Step 20142: Receive one or more second slave unit heartbeat messages from the base station group.

[0150] Among them, one or more second sub-station heartbeat messages are multicasted by other sub-base stations to the base station group respectively, and each second sub-station heartbeat message contains device information of other sub-base stations that send the second sub-station heartbeat message.

[0151] Exemplarily, the device information of other sub-base stations may include at least one of the following: an IP address of other sub-base stations, an ID of other sub-base stations, and a serial number of other sub-base stations.

[0152] Step 20143: Determine a second main base station from all sub-base stations in the base station group according to the second sub-base station heartbeat message received within the seventh preset time period and the device information of the sub-base station.

[0153] The seventh preset time length is a pre-set time length. The sub-base station starts timing when or after executing step 20141, and receives the heartbeat message of the second sub-station within the seventh preset time length.

[0154] The sub-base station determines the equipment information of all sub-base stations in the current base station group according to the equipment information of other sub-base stations carried in the heartbeat messages of the second sub-stations received within the seventh preset time period and its own equipment information.

[0155] The sub-base station may determine the first main base station based on the equipment information of all sub-base stations in the current base station group. Exemplarily, the sub-base station corresponding to the maximum value in the equipment information of all sub-base stations in the current base station group may be determined as the first main base station, or the sub-base station corresponding to the minimum value in the equipment information of all sub-base stations in the current base station group may be determined as the first main base station. The first main base station may also be determined in other ways, which are not limited in the present disclosure.

[0156] In this embodiment, each sub-base station in the base station group performs the following processing respectively: after confirming that the main base station has failed, the sub-base station sends a first sub-station heartbeat message to the base station group, and at the same time, after confirming that the main base station has failed, other sub-base stations send a second sub-station heartbeat message to the base station group. The sub-base station can determine all sub-base stations in the current base station group based on the device information of other sub-base stations carried in the second sub-station heartbeat message received within the seventh preset time length. The sub-base station determines the first main base station from all sub-base stations in the base station group based on the device information of all sub-base stations in the current base station group.

[0157] Furthermore, in another possible implementation of step 2014, it can be implemented through the following steps 2014a and 2014b.

[0158] Step 2014a: Determine the device information of all sub-base stations in the current base station group according to the heartbeat messages of each third sub-station received in the most recent period.

[0159] Step 2014b: Determine a second main base station from all sub-base stations in the current base station group according to the equipment information of all sub-base stations in the current base station group.

[0160] The sub-base station determines the equipment information of all sub-base stations in the current base station group according to the equipment information of other sub-base stations carried in the heartbeat messages of each third sub-station received in the most recent period and its own equipment information.

[0161] After determining that the main base station in the base station group is faulty, the sub-base station can determine the second main base station based on the equipment information of all sub-base stations in the current base station group. Exemplarily, the sub-base station corresponding to the maximum value in the equipment information of all sub-base stations in the current base station group can be determined as the first main base station, or the sub-base station corresponding to the minimum value in the equipment information of all sub-base stations in the current base station group can be determined as the first main base station. The first main base station can also be determined in other ways, which is not limited in this disclosure.

[0162] In this embodiment, the sub-base stations in the base station group periodically send sub-machine heartbeat messages to the base station group by multicast, wherein the sub-base station periodically sends sub-machine heartbeat messages to the base station group, and other sub-base stations periodically send third sub-machine heartbeat messages to the base station group. Since the third sub-machine heartbeat message can be received, it means that the sub-base station that sends the third sub-machine heartbeat message is still in the base station group. Therefore, the sub-base station can determine the sub-base stations in the current base station group according to the third sub-machine heartbeat message that is received periodically most recently. Thus, by periodically sending sub-machine heartbeat messages to the multicast group by the sub-base station, after determining that the main base station has failed, the sub-base station can quickly determine the sub-base stations in the current base station group according to the third sub-machine heartbeat message of the sub-base station received in the most recent period, thereby quickly determining the first main base station therefrom. The method for determining the failure of the first main base station is simple and easy to implement, and after the main base station fails, the sub-base station can quickly determine the first main base station, thereby quickly conducting self-organizing networking and providing services for terminal devices.

[0163] In some embodiments, after the sub-base station works in the single-station mode, if the fault of the sub-base station itself is repaired, the working mode can be switched back to the sub-station mode.

[0164] See also Figure 7 , Figure 7 A flowchart of a method for processing a base station failure provided by an embodiment of the present disclosure is provided. Figure 7 is Figure 3 On the basis of the illustrated embodiment, further, the following step 701 may be included after step 202 .

[0165] Step 701: If a second message sent by a master base station is received, the working mode is switched from a single-station mode to a slave-station mode.

[0166] The second message refers to any message sent when the main base station and the sub-base station interact with each other. The second message may be of the same type as the first message. For example, the second message may be a configuration message or a management message sent between the main base station and the sub-base station. After the main base station establishes a connection with the sub-base station, it sends a configuration message to the sub-base station to configure the connection, etc. During operation, the main base station may also periodically send a management message to the sub-base station, and the management message may also be a heartbeat message sent by the main base station.

[0167] In this embodiment, after the sub-base station works in the single-station mode, the main base station will also send a second message to the sub-base station to try to interact with the sub-base station. If the sub-base station can receive the second message sent by the main base station after its own fault is repaired, it can switch the working mode from the single-station mode to the sub-machine mode and join the base station group to continue working in the sub-machine mode. Among them, the sub-base station's own fault repair can be repaired manually or automatically.

[0168] In this embodiment, after the sub-base station switches the working mode to the single-station mode, the sub-base station provides services for the terminal device in the single-station mode. If the sub-base station receives the second message sent by the main base station, it can be considered that its own fault has been repaired. The sub-base station can switch the working mode from the single-station mode to the sub-machine mode, so that after the sub-base station fault is repaired, it joins the base station group and provides services for the terminal device in the sub-machine mode.

[0169] See also Figure 8 , Figure 8 A flowchart of a method for processing a base station failure provided in an embodiment of the present disclosure is provided in Figure 4 or Figure 5 Based on the embodiment shown, further, after step 202, the following step 801 may be included. It can be understood that Figure 8 For example, Figure 5 It is shown on the basis of the above description, which does not constitute a limitation of the present disclosure.

[0170] Step 801: If a heartbeat message sent by the master base station in a continuous period is received within a fifth preset time period, the working mode is switched from the single-station mode to the slave mode.

[0171] The fifth preset duration is greater than the cycle time. The cycle time refers to the cycle time during which the main base station periodically sends a heartbeat message to the sub-base station. Figure 4 In the embodiment shown, the cycle time is the cycle time for the main base station to periodically send heartbeat messages to the sub-base station in step 201a; Figure 5 In the illustrated embodiment, the periodic time is the periodic time for the primary base station to periodically send heartbeat messages to the secondary base stations in step 2011 .

[0172] Furthermore, the heartbeat message may include device information of the primary base station.

[0173] In this embodiment, after the sub-base station works in the single-station mode, the main base station will also send a heartbeat message to the sub-base station. If the sub-base station can receive the heartbeat message sent by the main base station after its own fault is repaired, it can switch the working mode from the single-station mode to the sub-machine mode and join the base station group to continue working in the sub-machine mode. Among them, the sub-base station's own fault repair can be repaired manually or automatically.

[0174] Furthermore, the sub-base station may re-establish a connection with the main base station according to the device information of the main base station in the heartbeat message, thereby continuing to work in the sub-base station mode.

[0175] In this embodiment, after the sub-base station switches the working mode to the single-station mode, the sub-base station provides services for the terminal device in the single-station mode. If the sub-base station receives a heartbeat message sent by the main base station, it can be considered that its own fault has been repaired. The sub-base station can switch the working mode from the single-station mode to the sub-machine mode, and then join the base station group after the sub-base station fault is repaired, and provide services for the terminal device in the sub-machine mode.

[0176] In some embodiments, based on any of the above embodiments, further, after step 202, the following step 203 may be included.

[0177] Step 203: Generate an event record.

[0178] The event record is used to instruct the sub-base station to switch the working mode from the sub-station mode to the single-station mode.

[0179] In this embodiment, by generating an event record for the switching behavior of the sub-base station, a basis is provided for the user to troubleshoot and repair the sub-base station, thereby enhancing the maintainability of the base station.

[0180] In some embodiments, based on any of the above embodiments, further, after step 202, the following step 204 may be included.

[0181] Step 204: Send alarm information to the base station management device.

[0182] Among them, the base station management device can be a device for managing a base station group, or it can be a terminal device or a server or other device that can receive alarm information, which is not limited in this disclosure.

[0183] The warning information is used to indicate a sub-base station failure. The warning information may be a message sent in the form of a data packet, a text message, or an email.

[0184] In this embodiment, alarm information is generated for the switching behavior of the sub-base station and sent to the base station management device to prompt the user to check and repair the sub-base station, thereby enhancing the maintainability of the base station, repairing the sub-base station fault in a timely manner, and providing better services for the terminal equipment.

[0185] Based on the base station failure processing method described in any of the above embodiments, the embodiment of the present disclosure further provides a computer-readable storage medium, for example, the non-temporary computer-readable storage medium may be a read-only memory (ROM), a random access memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, and an optical data storage device, etc. The storage medium stores computer instructions for executing the base station failure processing method described in any of the above embodiments, which will not be described in detail here.
