Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 202111583925.X, titled "Fault Detection Method, Signal Processing Device, and Control Device", filed with the China National Intellectual Property Administration on December 22, 2021, and the entire content of the Chinese patent application is incorporated herein by reference in its entirety.

[0002] This application relates to the field of communication technologies, and more specifically, to a fault detection method, a signal processing device, and a control device.

Background Art

[0003] When a fault occurs in a communication module within a communication system, the communication module can report an alarm for the fault. When the power of the communication module is turned off or when the communication module is in a sleep state, if the alarm still exists, when the power of the communication module is turned on again or when the communication module is awakened again, the alarm is erased due to power-off or sleep. However, when the power of the communication module is turned off or when the communication module is in a sleep state, the existing fault may not be recovered. After the alarm is erased, when the power of the communication module is turned on again or when the communication module is awakened again, there is no alarm in the communication module. Therefore, the communication system may misidentify that there is no fault in the communication module and needs to spend a long time to re-identify the fault that existed before power-off or sleep through fault detection. As a result, the efficiency of system maintenance is low. For example, when the radio frequency module of a base station is in a sleep state, there is a standing wave alarm in the radio frequency module. After the radio frequency module is awakened again, there is no standing wave alarm in the radio frequency module. Therefore, the base station misidentifies that there is no fault in the radio frequency module and cannot correct the fault in time.

[0004] Therefore, fault detection methods, signal processing devices, and control devices are urgently needed to improve the efficiency of system maintenance. [Overview of the project] [Means for solving the problem]

[0079] The technical solution of this application will be described below with reference to the attached drawings.

[0080] The technical solutions of the embodiments of this application may be applied to various communication systems, such as long-term evolution (LTE) systems, frequency division duplex (FDD) systems, time division duplex (TDD) systems, 5th generation (5G) systems, new radio (NR) systems, 6th generation (6G) systems, or future communication systems. The 5G mobile communication systems in this application include non-standalone (NSA) 5G mobile communication systems or standalone (SA) 5G mobile communication systems. The communication system may instead be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT) communication system, a vehicle-to-everything (V2X) communication system, an unmanned aerial vehicle (UAV) communication system, or another communication system.

[0081] In addition, the network architectures and service scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute limitations on the technical solutions provided in the embodiments of this application. As will be apparent to those skilled in the art, with the evolution of network architectures and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0082] To facilitate understanding of the embodiments of this application, we will first describe in detail the application scenarios of the embodiments of this application with reference to Figure 1.

[0083] Figure 1 is a diagram illustrating the structure of a communication system to which the embodiments of this invention can be applied. First, we will describe the devices that may be involved in the communication system.

[0084] 1. Main control transmitter (e.g., main processing and transmission module, MPT) 111: The main control transmitter is sometimes called the main control board. The MPT 111 may be located within a baseband unit (BU) 110 and can provide signaling processing and resource management functions for other boards within the BU 110 or boards connected to the BU 110, such as configuration management, device management, software management, performance monitoring, and alarm generation. The BU 110 may be a baseband unit (BBU), a central control unit (CU), a distributed control unit (DU), or another network element or communication device capable of processing baseband signals.

[0085] In this embodiment of the present application, the MPT 111 remains active for an extended period, receives and processes alarms reported by another substrate, and stores the alarms from the other substrate in the storage unit of the MPT 111 to form an alarm record.

[0086] 2. Baseband Processing Unit (e.g., baseband processing unit or baseband processor, BBP) 112: The baseband processing unit is sometimes also called a baseband board. The BBP 112 may be located within the BU 110 and can perform baseband signal processing functions, such as modulation, demodulation, coding, and decoding of baseband signals. It should be noted that the specific functions performed by the BBP 112 are related to the communication protocol used. This is not particularly limited in this application.

[0087] In this embodiment of the present application, the BBP 112 can independently perform power-off or sleep processing.

[0088] Please refer to Figure 1. Understand that the MPT 111 and BBP 112 are deployed within the same BU 110, and that the MPT 111 and BBP 112 can communicate with each other via an internal interface within the BU 110. In addition, the MPT 111 and BBP 112 may be two separate hardware devices with independent hardware within the BU 110, or they may be two functional modules deployed within the same hardware device.

[0089] 3. Radio Unit (RU) 130: The radio unit is sometimes called a radio frequency board. The RU 130 can perform functions such as intermediate frequency processing, radio frequency processing, and signal duplexing. For example, the RU 130 may be a remote radio unit (RRU), an active antenna unit (AAU), or another network element or communication device capable of processing intermediate frequency signals, radio frequency signals, or intermediate radio frequency signals. In some communication systems, for example, in a communication system using an enhanced common public radio interface (eCPRI), the RU 130 may further have some baseband processing functions. This is not particularly limited in this application.

[0090] In this embodiment of the present application, RU 130 can independently perform power-off or sleep processing.

[0091] The communication interface between BU 110 and RU 120 may be called a fronthaul interface, which may be a common public radio interface (CPRI), an eCPRI interface, or another interface to be used to connect BU 110 and RU 120 as defined in the future.

[0092] In addition, if the MPT 111 and BBP 112 are two independent hardware devices, the MPT 111 and BBP 112 may each have a front-haul interface for communication with the RU 120. If the MPT 111 and BBP 112 share a single hardware device, the MPT 111 and BBP 112 may share a front-haul interface for communication with the RU 120. This is not particularly limited in this application.

[0093] A distributed base station typically includes at least one BU and at least one RU. Each RU corresponds to one sector and provides radio access services on a single frequency band or multiple frequency bands. The networking scheme between BUs and RUs is described below with reference to Figure 2.

[0094] Figure 2 shows the structure of several networking systems to which one embodiment of this application is applicable. The system includes BU 210, RU 220, RU 230, and RU 240. See Figure 2(a). To form a directly connected network, BU 210 is directly connected to RU 220, RU 230, and RU 240. The BU communicates directly with the RUs via a fronthaul interface. See Figure 2(b). To form a chain network, BU 210 is directly connected to RU 220, RU 220 is directly connected to RU 230, and RU 230 is directly connected to RU 240. BU 210 communicates directly with RU 220, and BU 210 can communicate with RU 230 and RU 240 in a pass-through manner. See Figure 2(c). To form a ring network, BU 210 is directly connected to RU 220, RU 220 is directly connected to RU 230, RU 230 is directly connected to RU 240, and RU 240 is directly connected to BU 210. BU 210 can communicate directly with RU 220 and RU 240, and BU 210 can communicate with RU 230 using a pass-through method. See Figure 2(d). The system further includes BU 250 to form a dual-star network, so RU 210 is directly connected to BU 210 and BU 250. RU 210 can communicate directly with BU 210 and BU 250 individually.

[0095] The above describes only a few networking systems to which embodiments of this application may be applicable. Embodiments of this application may be further applicable to other networking systems to which RUs and BUs can communicate with each other. This is not particularly limited in this application.

[0096] If a failure occurs in a communication module within a communication system, such as the BBP or RU mentioned above, the communication module can report a failure alarm. If the alarm persists when the communication module is powered off or when the communication module is in a dormant state, the alarm is cleared when the communication module is powered on again or when the communication module is awakened again due to the power off or dormancy. However, failures in communication modules that are powered off or in a dormant state may not be recovered. After the alarm is cleared, when the communication module is powered on again or awakened again, the communication module will not have an alarm. In this case, it takes a long time for fault detection to re-identify the failure that existed before the power off or before dormancy. The communication system may mistakenly believe that there is no failure in the communication module. As a result, the efficiency of system maintenance is low. For example, when a base station's radio frequency module is in a dormant state, a standing wave alarm exists for the radio frequency module. After the radio frequency module is awakened again, the standing wave alarm for the radio frequency module does not exist. The base station mistakenly believes there is no fault in the radio frequency module and is unable to correct the fault in time.

[0097] Therefore, fault detection methods, signal processing devices, and control devices are urgently needed to improve the efficiency of system maintenance.

[0098] Figure 3 is a schematic flowchart of a fault detection method 300 according to one embodiment of this application.

[0099] S301: The signal processing unit acquires alarm information after the signal processing unit is initialized.

[0100] Alarm information instructs the signaling device that an alarm exists before initialization.

[0101] The signal processing device may be a BBP or RU as shown in Figure 1. For a description of the function of the signal processing device, please refer to the descriptions of the BBP and RU.

[0102] "After the initialization of the signal processing unit," "when the signal processing unit completes initialization," or "when the signal processing unit is restarted after initialization" may include, but are not limited to, the following cases: 1. The signal processing unit enters an awakened state from a dormant state, and in this application, "after entering the awakened state" means "after initialization." 2. The signal processing unit enters a powered-on state from a powered-off state, and in this application, "after entering the powered-on state" means "after initialization." 3. The signal processing unit performs an upgrade reset or an abnormal reset, and in this application, "after the upgrade reset or abnormal reset" means "after initialization."

[0103] It should be noted that initialization in this embodiment of the present application may mean the initialization of all or some modules in the signal processing device, or the complete or partial initialization of one module in the signal processing device. This is not particularly limited in this application.

[0104] The presence of an alarm in the signal processing unit before initialization may mean that the alarm exists before initialization, before it is cleared due to power off, sleep, or reset. For example, an alarm exists when the signal processing unit enters sleep mode, when the signal processing unit is powered off, and before the signal processing unit is reset. To clarify, refer to Figure 4 to illustrate the points in time when an alarm exists in the signal processing unit. Please refer to Figure 4. The first point in time is before initialization, and the second point in time is when initialization is complete. An alarm exists in the signal processing unit at the first point in time, and the signal processing unit acquires the alarm information at the second point in time. Let's take a sleep-wake scenario as an example. The signal processing unit enters sleep mode at the first point in time and is awakened at the second point in time. An alarm exists before the first point in time, and the signal processing unit maintains a sleep state between the first and second points in time. The signal processing unit acquires the alarm information at the second point in time, or after the second point in time (i.e., after initialization), and based on the alarm information, determines that an alarm existed in the signal processing unit at the first point in time.

[0105] Optionally, the alarm information field is a field that indicates to the signal processing unit that an alarm exists before initialization.

[0106] The alarm information will indicate the alarm type, which can be selected at will.

[0107] For example, an alarm type includes at least one of the following types: type of fault, type of fault, type of fault level, and type of network management.

[0108] It should be understood that the alarm information may indicate the alarm type of all alarms in the signal processing device, or it may indicate the alarm type of only one alarm in the signal processing device before initialization. This is not particularly limited in this application.

[0109] The type of faulty component can be a module within a signal processing unit, such as an optical module, interface module, or power supply module, and the system can indicate that a fault has occurred. For example, the alarm information can indicate the faulty component by specifying its location (e.g., the circuit board on which the faulty component is located).

[0110] The fault type can indicate the nature of a specific fault, such as a standing wave fault, overtemperature fault, overload fault, or abnormal fault. For example, alarm information can specify a standing wave value, and the signal processing unit can determine whether a standing wave fault exists based on whether the standing wave value exceeds a predetermined threshold. Alternatively, alarm information can specify an alarm identifier, and the signal processing unit can determine the nature of the fault based on the correspondence between the alarm identifier and the fault type.

[0111] The failure level type can indicate the severity of the failure, for example, whether it is a critical or minor failure. The network management type can indicate the network management system to which the failure belongs, for example, a relay system, communication system, environmental system, hardware system, or tolerance system.

[0112] In addition, the alarm type can further specify the network element to which the alarm belongs, the applicable RAT, the version to which it was installed, and so on. This is not particularly limited in this application.

[0113] The signal processing unit can acquire alarm information using multiple methods. These methods will be described separately below.

[0114] Method 1: The control unit generates alarm information.

[0115] The signal processing unit receives alarm information from the control unit.

[0116] The control device may be the MPT shown in Figure 1. For a description of the control device's functions, please refer to the description of the MPT.

[0117] The control device can store alarms that exist before the initialization of the signal processing device managed by the control device, and can generate alarm information based on the stored alarms.

[0118] The control unit may store all alarms of the signaling device, or it may store only alarms that existed before the initialization of the signaling device. For example, in a dormancy / wake-up scenario, the signaling device may be set to dormancy at a first time point, and the control unit can determine whether there are alarms in the signaling device at that first time point. If there are alarms in the signaling device, the control unit stores the alarms or stores a field indicating that there were alarms in the signaling device before initialization.

[0119] If the signal processing unit is a BBP (Blockhead Processor), the control unit can transmit alarm information to the signal processing unit via an electrical interface. If the signal processing unit is an RRU (Rapid Load Unit), the control unit can transmit alarm information directly to the signal processing unit via a fronthaul interface, or it can transmit alarm information to the signal processing unit via a pass-through method, based on the various networking schemes shown in Figure 2.

[0120] In this way, in Method 1, once the signal processing unit has completed initialization, the control unit can proactively transmit alarm information to the corresponding signal processing unit.

[0121] Method 2: The signal processing unit sends a request message to the control unit, which is used to request the acquisition of alarm information.

[0122] The control unit transmits alarm information to the signal processing unit based on the request message.

[0123] The explanation regarding the control device and communication between the control device and the signal processing device is the same as in Method 1. For brevity, the details will not be explained again here.

[0124] In this way, in method 2, once initialization is complete, the signal processing unit can send a request message to the control unit, and the control unit sends alarm information to the signal processing unit in response to the request message.

[0125] Method 3: The signal processing unit stores any alarms present in the signal processing unit before initialization.

[0126] The signal processing unit determines alarm information based on alarms that existed before initialization.

[0127] The signaling device may store all of its alarms, or it may store only the alarms that existed before initialization. For example, in a dormancy / wake-up scenario, the signaling device may be set to dormancy at a first time point, and the signaling device can determine whether there are any alarms at the signaling device at that first time point. If there are alarms at the signaling device, the signaling device stores the alarms, or stores a field indicating that there were alarms at the signaling device before initialization.

[0128] In this way, in method 3, the signal processing device stores alarms that existed before initialization, and can determine alarm information based on the alarms stored by the signal processing device.

[0129] S302: The signal processing unit performs fault detection based on the alarm information.

[0130] After acquiring alarm information, the signal processing unit can know that a fault may exist in the signal processing unit itself and that it has not been processed, and therefore, the signal processing unit can perform fault detection based on the alarm information.

[0131] If the alarm information indicates the alarm type, then fault detection can correspond to that alarm type.

[0132] As an example, if the alarm information indicates the type of fault, the signaling device only needs to detect the indicated fault. As another example, if the alarm information indicates the type of fault, the signaling device only needs to detect that type of fault. As yet another example, if the alarm information indicates the type of fault level, the signaling device can perform detection using various strategies based on the various fault levels.

[0133] As an optional feature, the signal processing unit can accelerate fault detection based on alarm information.

[0134] For example, a signal processing device is pre-configured to perform the first fault detection again when initialization is complete. Upon acquiring alarm information, the signal processing device can select a faster method than the first fault detection to perform fault detection based on the alarm information.

[0135] As an optional feature, the signal processing unit may set its operating status to an abnormal state based on the alarm information.

[0136] An abnormal state can indicate that a fault exists in the signal processing unit. For example, the operating status of a signal processing unit includes both a normal state and an abnormal state. A signal processing unit in a normal state does not need to perform fault detection, while a signal processing unit in an abnormal state is specified to perform abnormal state detection. Alternatively, a signal processing unit in a normal state is specified to perform fault detection, while a signal processing unit in an abnormal state is specified to accelerate fault detection. In this way, to avoid cases where a signal processing unit mistakenly believes that there is no fault in the signal processing unit after initialization, a signal processing unit that has received alarm information can directly set its operating status to an abnormal state.

[0137] The following describes a method by which a signal processing device performs fault detection based on alarm information.

[0138] Method a: The signal processing unit determines the first parameter based on the alarm information.

[0139] The signal processing unit performs fault detection using the first parameter.

[0140] The first parameter may include at least one of the following parameters: namely, the detection period and the number of detection / confirmation counts.

[0141] The detection cycle may be the cycle over which fault detection is performed multiple times, and the number of detection / confirmation cycles may be the number of times fault detection is performed multiple times. For example, in some scenarios, the signal processing device is configured to perform fault detection multiple times and, based on the results of the multiple fault detections, determine whether a fault exists, or a specific fault that exists. In this case, the signal processing device can determine the detection cycle and / or the number of detection / confirmation cycles based on alarm information.

[0142] If the alarm information indicates the alarm type, then the first parameter may correspond to the alarm type.

[0143] For example, if alarm information indicates that the fault level is critical, the signal processing unit can determine a short detection cycle or a small number of detection / confirmation attempts so that the fault can be corrected in a timely manner. In other words, the signal processing unit can determine various primary parameters based on various alarm types in order to perform fault detection.

[0144] Optionally, the first parameter is used to accelerate fault detection. Alternatively, the first parameter is used to shorten the detection cycle and / or reduce the number of detection and confirmations.

[0145] For example, the signal processing device may be pre-configured to perform a first fault detection using pre-configured parameters when initialization is complete. Upon acquiring alarm information, the signal processing device can determine the first parameters based on the alarm information, for example, by determining a shorter detection cycle and / or fewer checks than the pre-configured parameters. Therefore, the speed of fault detection performed using the first parameters is faster than the speed of first fault detection performed using the pre-configured parameters. In addition, in this case, the first parameters may be dynamically selected by the signal processing device based on the alarm information, or they may be one parameter from a set of parameters pre-configured by the signal processing device that enables rapid detection. The signal processing device may directly select parameters based on the alarm information in order to perform fault detection.

[0146] As an optional choice, in method a, step S303 may be performed before step S302 of method 300.

[0147] S303: The signal processing unit receives environmental information from the control unit.

[0148] Environmental information is used to determine a first parameter used for fault detection. The signal processing unit determines the first parameter based on alarm information and environmental information.

[0149] Environmental information may include at least one of the following: path quality information, power information, and loss information. It should be understood that in this application, environmental information may further include other parameters that can be used by the signal processing unit to perform fault detection, such as temperature information and humidity information.

[0150] Route quality information can indicate information such as jitter, packet loss rate, bit error rate, and bandwidth of the route used by the signaling device to send and receive information. Power information can indicate information such as the power used by the signaling device to send and receive information. Loss information can indicate information such as the loss of the optical path of the signaling device. In this way, the signaling device can determine a first parameter based on the environmental information. For example, if the environmental information indicates that the current route quality is poor, the signaling device can select a faster method to perform fault detection.

[0151] Thus, in method a, the signal processing device can determine a first parameter for fault detection.

[0152] Method b: The control unit determines a first parameter based on the alarm information.

[0153] The signal processing unit receives a first parameter from the control unit.

[0154] The signal processing unit performs fault detection using the first parameter.

[0155] It should be understood that when the signal processing device receives alarm information from the control device using method 1, the signal processing device can also receive a first parameter from the control device using method b.

[0156] The method by which the control device determines the first parameter is the same as the method by which the signal processing device determines the first parameter as described in method a. For brevity, the details will not be explained again here.

[0157] In this way, in method b, the control device can determine a first parameter used for fault detection and transmit the first parameter to the signal processing device for fault detection.

[0158] Thus, in this application, once the signal processing device completes initialization, the signal processing device acquires alarm information, and based on the alarm information, it can know that an alarm existed in the signal processing device before initialization, and can perform fault detection based on the alarm information, thereby improving the efficiency of system maintenance.
