[0002] At present, 5G base stations for mining usually include a baseband unit (BBU) and a remote radio unit (RRU). One baseband unit can be cascaded with multiple remote radio units to form a cascade network. Figure 1 , Figure 1 This is a schematic diagram of the cascade networking of traditional 5G base stations.

[0003] In the traditional cascade networking mode, the data and signaling of each remote radio unit need to be sent to the baseband processing unit through the upper-level remote radio unit, and then forwarded to the core network after being processed by the baseband processing unit. However, when a remote radio unit at a certain level of the cascade fails or the communication link is abnormal, the data and signaling of the remote radio unit at that level and the subsequent cascaded remote radio units cannot be sent to the baseband processing unit, affecting 5G communications within the coverage area of ​​the base station.

[0032] Before executing the technical solution provided by the present invention, the application scenario may be described first. The 5G network includes a core network, a baseband processing unit in communication with the core network, and multiple radio frequency remote units. In an embodiment of the present invention, multiple radio frequency remote units are cascaded according to a first target cascade sequence, and the radio frequency remote unit at the first target cascade sequence communicates with the first interface of the baseband processing unit, and the radio frequency remote unit at the end of the first target cascade sequence is connected to the second interface of the baseband processing unit, and the second interface is in a disabled state. Based on the above networking method, the technical solution provided in this embodiment is applied.

[0033] Embodiment 1

[0034] Figure 2 This is a flowchart of a fault handling method based on 5G networking provided in the first embodiment of the present invention. This embodiment can be applied to the situation where a radio frequency remote unit in a mining 5G base station fails or the communication link is abnormal, and the communication is quickly restored through the second interface of the baseband processing unit. The method can be executed by a fault handling device based on 5G networking, which can be implemented in the form of hardware and / or software. The fault handling device based on 5G networking can be configured in electronic devices such as mobile phones, computers or servers. Figure 2 As shown, the method includes:

[0035] S110: Send the heartbeat information generated by the baseband processing unit to the multiple radio remote units based on the first interface, so that the radio remote units feed back feedback data corresponding to the heartbeat information.

[0036] Among them, the 5G network includes a core network, a baseband processing unit in communication with the core network, and multiple radio frequency remote units. The core network can be used to process user data, manage user sessions, and provide mobility management operations. The baseband processing unit (Base Band Unit, BBU) can be used to process the digital signal of the base station, including operations such as encoding, decoding, modulation, and demodulation of the signal. The baseband processing unit can be connected to multiple radio frequency remote units, and each radio frequency remote unit can be used to collect radio frequency signals within the corresponding coverage range. The radio frequency remote unit (Remote Radio Unit, RRU) is used to convert the digital signal processed by the baseband processing unit into a radio frequency signal and transmit it through the antenna, while receiving the radio frequency signal from the user, and converting the radio frequency signal into a digital signal and transmitting it back to the baseband processing unit. Radio frequency remote units are usually deployed in locations such as the top of the base station tower or the outer wall of a building to provide better signal coverage.

[0037] Before executing the technical solution provided by the present invention, the networking method used in the embodiment of the present invention can be described. In the embodiment of the present invention, multiple radio remote units are cascaded according to a first target cascade sequence, the radio remote unit at the first target cascade sequence communicates with the first interface of the baseband processing unit, and the radio remote unit at the end of the first target cascade sequence is connected to the second interface of the baseband processing unit, and the second interface is in a disabled state.

[0038] Among them, the base station processing unit may include multiple communication interfaces for establishing a communication link with the radio frequency remote unit. The first interface and the second interface are both communication interfaces of the base station processing unit. The priority of the first interface is higher than the priority of the second interface. It should be noted that the priority of the first interface and the second interface can be pre-set according to actual needs. The first interface with a higher priority usually has a higher bandwidth, lower network latency, and stronger error correction capability to ensure the reliability and stability of data transmission.

[0039] The base station processing unit can establish a communication link with the radio remote unit by sending a link establishment request to each radio remote unit according to the order of information fed back by the radio remote unit based on the link establishment request. That is, the first target cascade order can be determined according to the order of information fed back by the radio remote unit based on the link establishment request, and can be a cascade order set according to actual needs. The disabled state can be understood as a state in which communication is not possible. The second interface in the disabled state cannot establish a communication link with the radio remote unit.

[0040] The heartbeat information, i.e., the heartbeat signal, can be used to determine whether the communication link between the baseband processing unit and the radio remote unit is disconnected, and whether the radio remote unit connected to the baseband processing unit is faulty. The feedback data can be information fed back by the radio remote unit based on the received heartbeat information.

[0041] Specifically, for at least two communication interfaces included in the baseband processing unit, two communication interfaces are selected as the first interface and the second interface according to actual needs. Multiple radio remote units are cascaded according to the first target cascade sequence, the radio remote unit at the first target cascade sequence communicates with the first interface of the baseband processing unit, and the radio remote unit at the end of the first target cascade sequence is connected to the second interface of the baseband processing unit, and after the above communication link is established, the second interface is set to a disabled state. On this basis, the heartbeat information generated by the baseband processing unit is sent to multiple radio remote units at preset time intervals based on the first interface. After receiving the heartbeat information of the baseband processing unit, the radio remote unit decodes the heartbeat information and generates feedback data corresponding to the heartbeat information. The radio remote unit feeds back the feedback data to the baseband processing unit, so that after receiving the feedback data, the baseband processing unit determines that the corresponding radio remote unit has not failed, and the baseband processing unit can communicate normally with the corresponding radio remote unit.

[0042] Optionally, the radio remote unit may also send heartbeat information to the baseband processing unit at preset intervals, so as to determine that the radio remote unit and the baseband processing unit can communicate normally when the radio remote unit receives feedback data corresponding to the heartbeat information fed back by the baseband processing unit.

[0043] In an embodiment of the present invention, a method for determining a first target cascade order corresponding to a plurality of remote radio frequency units may be: sending a link establishment request generated by a baseband processing unit to a plurality of remote radio frequency units based on a first interface and a second interface; and determining a first target cascade order of the plurality of remote radio frequency units based on timing information of receiving the link establishment information, when link establishment information fed back by the plurality of remote radio frequency units is received based on the first interface and the second interface, and when the media access control addresses received by the first interface and the second interface are the same.

[0044] The link establishment request may be a request generated by the baseband processing unit for establishing a link with the radio remote unit. The link establishment information may be information generated by the radio remote unit based on the received link establishment request, agreeing to establish a link with the baseband processing unit. The link establishment information carries the media access control address of the radio remote unit. The media access control address (MAC address) may be understood as a unique physical address for identifying the radio remote unit. The timing information may be understood as the sequence information of the media access control addresses of the radio remote unit received by the first interface.

[0045] Specifically, the link establishment request generated by the baseband processing unit is sent to multiple remote radio frequency units according to the first interface and the second interface of the baseband processing unit. That is, the first interface sends the link establishment request to the multiple remote radio frequency units. After receiving the link establishment request, the multiple remote radio frequency units parse the link establishment request and generate link establishment information corresponding to the link establishment request and carrying the media access control address, so as to send the link establishment information to the first interface. Accordingly, the second interface sends the link establishment request generated by the baseband processing unit to the multiple remote radio frequency units. After receiving the link establishment request, the remote radio frequency unit feeds back the link establishment information corresponding to the link establishment request and carrying the media access control address to the second interface. When the media access addresses corresponding to the remote radio frequency units received by the baseband processing unit are consistent, since the priority of the first interface is higher than that of the second interface, the first target cascade sequence of the multiple remote radio frequency units is determined based on the timing information of the first interface according to the received link information, so that the baseband processing unit establishes communication with the multiple remote radio frequency units through the first interface.

[0046] For example, see Figure 3 , Figure 3 A schematic diagram of the cascaded network corresponding to the 5G base station for mining provided in an embodiment of the present invention. The 5G base station for mining includes a baseband unit (BBU) and a remote radio unit (RRU). The baseband unit can be connected to multiple remote radio units to form a cascaded network, and the last level of remote radio unit is connected to the baseband unit again to form a ring-shaped network architecture. That is, Figure 3 RRU1 is connected to the baseband processing unit BBU through the 1# interface, and RRU1 is cascaded to five radio remote units, namely RRU2, RRU3, RRU4, RRU5 and RRU6. RRU6 is connected to the baseband processing unit BBU through the 2# interface.

[0047] There may be multiple communication interfaces for the baseband processing unit to communicate with the radio remote unit. Each communication interface has a default or preset priority. If the baseband processing unit includes 4 communication interfaces, and the priorities are 1# interface, 2# interface, 3# interface, and 4# interface from high to low. Take the first interface as 1# interface and the second interface as 2# interface as an example for explanation. When the baseband processing unit establishes a link with the radio remote unit, the baseband processing unit periodically sends a link establishment request to RRU1, RRU2, RRU3, RRU4, RRU5, and RRU6 through 1# interface and 2# interface at the same time. RRU1, RRU2, RRU3, RRU4, RRU5, and RRU6 will receive two link establishment requests, and send link establishment information to 1# interface and 2# interface respectively to agree to establish the link, and the link establishment information carries the MAC address of the radio remote unit itself. When the two groups of link establishment information carrying MAC addresses received by the 1# interface and the 2# interface are completely consistent, the baseband processing unit determines the first target cascade sequence of multiple radio remote units as: RRU1→RRU2→RRU3→RRU4→RRU5→RRU6 according to the timing information of the link establishment information received by the 1# interface. According to the above-mentioned first target cascade sequence, it communicates with the 1# interface, and connects RRU6 to the baseband processing unit through the 2# interface. According to the priority of the 1# interface and the 2# interface, the 2# interface is automatically blocked, that is, the 2# interface is set to a disabled state, so that the baseband processing unit communicates with RRU1 to RRU6 through the 1# interface.

[0048] Figure 3 The baseband processing unit BBU and the radio remote unit RRU in the baseband processing unit periodically send heartbeat information to each other to confirm the working status of the other end. That is, the baseband processing unit sends heartbeat information to RRU1 to RRU6 through the 1# interface, so that RRU1 to RRU6 feed back feedback data corresponding to the heartbeat information. Correspondingly, RRU1 to RRU6 send heartbeat information to the baseband processing unit through the 1# interface, so that the baseband processing unit feeds back feedback data corresponding to the heartbeat information.

[0049] S120: If the feedback data fed back by the at least one RF remote unit to be processed is not received based on the first interface, the second interface is controlled to be changed from a disabled state to an enabled state, and a link establishment request generated by the baseband processing unit is sent to the at least one RF remote unit to be processed based on the second interface.

[0050] The RF remote unit to be processed may be a RF remote unit that does not feed back feedback data corresponding to the heartbeat information. Optionally, when a RF remote unit fails, the RF remote unit and the RF remote units cascaded under the RF remote unit cannot feed back feedback data corresponding to the heartbeat information. The available state can be understood as a state in which communication can be established with the RF remote unit.

[0051] Specifically, if the baseband processing unit does not receive feedback data fed back by at least one remote radio frequency unit to be processed through the first interface, it indicates that at least one remote radio frequency unit to be processed is faulty, and the second interface is controlled to be changed from a disabled state to an available state. A link establishment request generated by the baseband processing unit is sent to at least one remote radio frequency unit to be processed according to the second interface, so as to realize communication with the remote radio frequency unit to be processed based on the second interface.

[0052] Exemplarily, in combination with the above examples, when Figure 3 When RRU3 fails, if interface 1# fails to receive feedback data from RRU3, RRU4, RRU5 and RRU6 for three consecutive times, interface 2# is changed from disabled to available. Link establishment request is sent to RRU3, RRU4, RRU5 and RRU6 through interface 2# to establish communication link with RRU3, RRU4, RRU5 and RRU6.

[0053] S130: when link establishment information fed back by the target remote radio unit is received based on the second interface, determine a second target cascading sequence of the target remote radio unit, so that the target remote radio unit communicates with the baseband processing unit through the second interface after cascading based on the second target cascading sequence.

[0054] The target remote radio unit is a remote radio unit in at least one remote radio unit to be processed. The second target cascade sequence may be determined according to the first target cascade sequence. It can be understood that the second target cascade sequence may be the reverse order of the target remote radio units in the first target cascade sequence.

[0055] Specifically, when the second interface receives the link establishment information fed back by the target radio remote unit, the second target cascade sequence of the target radio remote unit is determined according to the first target cascade sequence and the media access control address carried in the link establishment information, while ensuring that the media access control address received by the second interface is not repeated with the media access control address received by the first interface, so that the target radio remote unit communicates with the baseband processing unit through the second interface after being cascaded through the second target cascade sequence.

[0056] Exemplarily, in combination with the above example, when the 2# interface receives the link establishment information fed back by RRU4, RRU5 and RRU6, the baseband processing unit determines that the MAC address received by the 2# interface is not repeated with the 1# interface according to the MAC address in the link establishment information, and determines the second target cascade sequence to be RRU6→RRU5→RRU4 according to the first target cascade sequence. Based on this, the baseband processing unit communicates with RRU4, RRU5 and RRU6 through the 2# interface, and communicates with RRU1 and RRU2 through the 1# interface.

[0057] In an embodiment of the present invention, the second target cascade order of the target remote radio frequency unit may be determined by: when the link establishment information and the media access control address fed back by the target remote radio frequency unit are received based on the second interface, the second target cascade order of the target remote radio frequency unit is determined based on the cascade order corresponding to the media access control address in the first target cascade order.

[0058] Specifically, when the link establishment information carrying the media access control address is received from the target remote radio frequency unit based on the second interface, the reverse order of the cascade sequence corresponding to the media access control addresses of each target remote radio frequency unit in the first target cascade sequence is used as the second target cascade sequence of the target remote radio frequency unit.

[0059] The technical solution of this embodiment is to send the heartbeat information generated by the baseband processing unit to multiple radio remote units according to the first interface, so that the radio remote unit feeds back feedback data corresponding to the heartbeat information. Based on this, it can be determined whether there is a faulty radio remote unit through the feedback data. If the feedback data fed back by at least one radio remote unit to be processed is not received based on the first interface, the second interface is controlled to change from a disabled state to an available state, and the link establishment request generated by the baseband processing unit is sent to at least one radio remote unit to be processed based on the second interface. When the link establishment information fed back by the target radio remote unit is received based on the second interface, the second target cascade sequence of the target radio remote unit is determined, so that the target radio remote unit communicates with the baseband processing unit through the second interface after cascading based on the second target cascade sequence. The technical solution of the present invention solves the problem in the prior art that the data and signaling of the radio remote unit and the radio remote units cascaded thereafter cannot be sent to the baseband processing unit due to the failure of a certain radio remote unit, so that the 5G terminal devices within the coverage area corresponding to these radio remote units lose the 5G signal, affecting normal communication. The technical solution provided by the present invention can establish a link with the radio remote unit through the second interface of the baseband processing unit when a radio remote unit fails or the link is abnormal, so as to quickly restore communication and ensure the normal operation of the network.

[0060] Embodiment 2

[0061] Figure 4 This is a flowchart of a fault handling method based on 5G networking provided by Embodiment 2 of the present invention. This embodiment is a preferred embodiment of the above embodiment. For its specific implementation, please refer to the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Figure 4 As shown, the method includes:

[0062] S210: Send the heartbeat information generated by the baseband processing unit to the multiple radio remote units based on the first interface, so that the radio remote units feed back feedback data corresponding to the heartbeat information.

[0063] S220: If the feedback data fed back by at least one RF remote unit to be processed is not received based on the first interface, and the number of times the feedback data is not received reaches a preset number threshold, the second interface is changed from a disabled state to an available state, and a link establishment request generated by the baseband processing unit is sent to at least one RF remote unit to be processed based on the second interface.

[0064] The preset number threshold may be a pre-set number of times that feedback data is not received. By setting the preset number threshold, the problem of misjudging the failure of the radio remote unit due to failure to receive feedback data due to network fluctuations can be avoided. For example, the preset number threshold may be 3 times, that is, when the baseband processing unit fails to receive feedback data from a certain radio remote unit to be processed through the first interface for 3 consecutive times, it can be considered that the radio remote unit to be processed may be in a faulty state, or a certain upper cascaded radio remote unit to be processed of the radio remote unit to be processed is in a faulty state.

[0065] Specifically, if the baseband processing unit does not receive feedback data fed back by at least one radio remote unit to be processed through the first interface, and the number of times the feedback data is not received reaches a preset number threshold, the second interface is changed from a disabled state to an enabled state to establish communication with at least one radio remote unit to be processed through the second interface. That is, the link establishment request generated by the baseband processing unit is sent to at least one radio remote unit to be processed based on the second interface.

[0066] S230: when link establishment information fed back by the target remote radio unit is received based on the second interface, determine a second target cascading sequence of the target remote radio unit, so that the target remote radio unit communicates with the baseband processing unit through the second interface after cascading based on the second target cascading sequence.

[0067] The target remote radio unit is a remote radio unit in at least one remote radio unit to be processed.

[0068] S240: upon receiving an instruction that the faulty remote radio unit can use, sending the link establishment request generated by the baseband processing unit to the faulty remote radio unit and at least one target remote radio unit based on the first interface, so that the faulty remote radio unit and the at least one target remote radio unit feed back link establishment information and a media access control address.

[0069] The faulty radio remote unit may be a radio remote unit whose number of unfed feedback data reaches a preset number threshold and which is unable to establish communication with the second interface.

[0070] Specifically, when feedback data fed back by the faulty remote radio unit based on the heartbeat information is received based on the first interface, instructions that can be used by the faulty remote radio unit are determined based on the feedback data. A link establishment request generated by the baseband processing unit is sent to the faulty remote radio unit and at least one target remote radio unit based on the first interface, so that when link establishment information and a media access control address fed back by the faulty remote radio unit and at least one target remote radio unit are received, communication is performed with the faulty remote radio unit and the target remote radio unit through the first interface.

[0071] S250: When link establishment information and a media access control address are fed back from a faulty remote radio unit and at least one target remote radio unit based on the first interface, cascade all remote radio units based on a first target cascade sequence.

[0072] Specifically, when link establishment information carrying a media access address is received from a faulty remote radio unit and at least one target remote radio unit through the first interface, all remote radio units are cascaded according to a first target cascade sequence to communicate with all remote radio units through the first interface.

[0073] For example, in conjunction with the above examples, see Figure 3 When the faulty remote radio unit RRU3 can feed back feedback data corresponding to the first interface and the heartbeat information, the faulty remote radio unit RRU3 is considered to be usable. A link establishment request is sent to RRU3, RRU4, RRU5 and RRU6 through the 1# interface, so that when the 1# interface receives the link establishment information including the MAC address fed back by RRU3, RRU4, RRU5 and RRU6, all remote radio units are cascaded based on the first target cascade sequence, and a communication link is established with RRU1 to RRU6 through the 1# interface.

[0074] Optionally, when the first interface receives data corresponding to the heartbeat packets fed back by multiple radio remote units, the second interface is adjusted from an available state to a disabled state.

[0075] The heartbeat packet, namely the heartbeat information, may be a data packet used to determine whether the communication link between the baseband processing unit and the radio remote unit is disconnected. The data corresponding to the heartbeat packet may be understood as feedback data fed back by the radio remote unit according to the heartbeat packet sent by the first interface.

[0076] Specifically, when data corresponding to the heartbeat packet is received from all radio remote units through the first interface, it means that all radio remote units can communicate with the baseband processing unit through the first interface, and the second interface can be adjusted from an available state to a disabled state to communicate with the radio remote units through the high-priority first interface.

[0077] The technical solution of this embodiment is to send the heartbeat information generated by the baseband processing unit to multiple remote radio units according to the first interface, so that the remote radio units feedback feedback data corresponding to the heartbeat information. Based on this, it can be determined whether there is a faulty remote radio unit through the feedback data. If the feedback data fed back by at least one remote radio unit to be processed is not received based on the first interface, and the number of times the feedback data is not received reaches the preset number threshold, the second interface is changed from a disabled state to an available state, and the link establishment request generated by the baseband processing unit is sent to at least one remote radio unit to be processed based on the second interface. When the link establishment information fed back by the target remote radio unit is received based on the second interface, the second target cascade sequence of the target remote radio unit is determined, so that the target remote radio unit communicates with the baseband processing unit through the second interface after cascading based on the second target cascade sequence. When the instruction that the faulty remote radio unit can be used is received, the link establishment request generated by the baseband processing unit is sent to the faulty remote radio unit and at least one target remote radio unit based on the first interface, so that the faulty remote radio unit and at least one target remote radio unit feedback the link establishment information and the media access control address. When the link establishment information and the media access control address are received based on the first interface from the faulty RF remote unit and at least one target RF remote unit, all RF remote units are cascaded based on the first target cascade sequence, so that the baseband processing unit establishes communication with all RF remote units through the first interface. The technical solution of the present invention solves the problem in the prior art that due to the failure of a certain RF remote unit, the data and signaling of the RF remote unit and the RF remote units cascaded thereafter cannot be sent to the baseband processing unit, causing the 5G terminal devices within the coverage range corresponding to these RF remote units to lose the 5G signal, affecting normal communication. The technical solution provided by the present invention can establish a link with the RF remote unit through the second interface of the baseband processing unit when a certain RF remote unit fails or the link is abnormal, so as to quickly restore communication and ensure the normal operation of the network.

When the link establishment information fed back by the target radio remote unit is received based on the second interface, the second target cascade sequence of the target radio remote unit is determined, so that the target radio remote unit communicates with the baseband processing unit through the second interface after cascading based on the second target cascade sequence.
