Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a detection method and device for a main control board and network equipment. Background Art

[0002] With the promotion of 5G technology, remote maintenance of base stations, as the operator's preferred operation and maintenance method, has entered a new stage. Faced with the challenges of more diversified networking scenarios, the control unit fault detection function has become an important part of base station maintenance. In the scenario where the 5G New Radio (NR) cell is activated, when the main control board of the base station is unavailable or not in place due to a main control board failure or human factors, the baseband board will not actively shut down the NR cell function. There is only one way to manually shut it down on the station. Before this, the NR cell of the baseband board is in a managed state. At this time, if the NR cell cannot perform synchronous code stream calibration for a long time, the cell will become an abnormal signal transmission site that interferes with adjacent cells, affecting the user access success rate of nearby normal cells. The impact can only be eliminated by manually shutting down the cell on the station, which increases the operation and maintenance cost.

[0003] In currently operating 5G NR base stations, the typical fault monitoring solution is for the master control unit to monitor the operating status of subordinate devices. Upon detecting a fault in the baseband unit or other subordinate devices, it initiates a recovery process to resolve the source of the fault. If a 5G NR base station's master control unit experiences a software or hardware failure (one that cannot be recovered automatically), the NR cell cannot be deleted. Long-term operation is likely to introduce local interference, impacting the performance of regional key performance indicators (KPIs). Summary of the Invention

[0004] The embodiments of the present invention provide a main control board detection method, device and network equipment to solve the problem that the main control board of the prior art 5GNR base station has hardware and software failures, resulting in the NR cell being in a managed state, and there is a high probability of introducing local interference after long-term operation.

[0047] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments of the present invention. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0053] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0054] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] Currently, only the main control board (MCB) in base stations checks the presence of the baseband board, but the baseband board does not detect the presence of the MCB. The MCB obtains the presence of the board by reading information from the registers of the Erasable Programmable Logic Device (EPLD) via a two-wire serial bus (Inter-Integrated Circuit, I2C). The baseband board cannot use the EPLD to control the I2C link to reversely monitor the presence of the MCB. In other words, the existing 5G NR software architecture has an access control process for the MCB to monitor the baseband board at the operation and maintenance level, but no reverse monitoring process for the baseband board. Furthermore, the existing 5G NR software architecture lacks a heartbeat detection mechanism between the MCB (or MCU) and the baseband board (or BBU), making it impossible to flexibly identify faulty units. If the MCB is not present, the baseband board becomes out of control and can only be restored to its initial state by performing a site reset, increasing operation and maintenance costs.

[0057] Therefore, the embodiments of the present application provide a detection method, device and network equipment for a main control board. The baseband board can determine whether the main control board is abnormal based on the number of times the detection response message is not received, and automatically perform a reset operation when the main control board is determined to be abnormal, so as to reduce interference to the surrounding normal cells and reduce operation and maintenance costs.

[0058] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0059] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0060] Specifically, such as Figure 1 As shown, an embodiment of the present invention provides a detection method for a main control board, which is applied to a baseband board. The method specifically includes:

[0061] Step 101 : When the Protocol Adapter Module (PAM) of the standard protocol stack of the main process of the baseband board is started, main control board information is obtained at intervals of a first preset time.

[0062] Specifically, if the protocol adaptation layer PAM of the baseband board main process standard protocol stack is started, after the PAM of the baseband board main process standard protocol stack is started, the main control board information is periodically obtained. The period is the first preset duration, that is, the main control board information is obtained once every first preset duration. The value range of the first preset duration can be 1ms~1min, and can be set specifically as needed.

[0063] Step 102: Send a detection message to the main control board according to the main control board information, wherein the detection message includes: information of a first main control board of the main control board receiving the detection message.

[0064] Specifically, if the main control board information is not obtained, a detection message is constructed, and the detection message can be an operating system platform (OSP) header detection message. Since the main control board information is not obtained, the standard protocol stack PAM position of the main control board used to receive the detection message cannot be accurately known, that is, it is not known whether the main control board is in slot 0 or slot 1, so the baseband board needs to send the detection message to slot 0 and slot 1 respectively. Among them, the destination software function unit identity document (SFUID) is filled in the detection message. The destination SFUID is used to indicate the first main control board information of the main control board that receives the detection message. The first main control board information includes the location information of the main control board that receives the detection message, etc.

[0065] If the protocol adaptation layer PAM of the baseband board main process standard protocol stack is started, after the baseband board main process standard protocol stack PAM is started, if the main control board information is obtained, an OSP header detection message is constructed according to the main control board information, and the destination SFUID is filled in the detection message. The destination SFUID is used to indicate whether the main control board receiving the detection message is in slot 0 or slot 1, that is, the location information of the main control board receiving the detection message can be accurately known according to the destination SFUID.

[0066] It should be noted that the baseband board can send a detection message to the main control board standard protocol stack PAM through the base station internal communication port number 20000 link.

[0067] Step 103: If the main control board fails to detect a probe response message fed back by the main control board according to the probe message for N consecutive times, it is determined that the main control board is faulty, where N is a positive integer greater than 1.

[0068] Specifically, after the baseband board sends a probe message to the main control board, the baseband board detects the probe response message fed back by the main control board based on the probe message. If the baseband board fails to detect the fed-back probe response message after sending N probe messages to the main control board, it is determined that no probe response message has been detected N times in a row, and the main control board is faulty. Main control board faults include situations where the main control board is abnormal, unusable, or not in place. The value of N can be a multiple of 4, for example, 128 or 256.

[0069] It should be noted that N is a preset value, which refers to whether the number of consecutive failures to receive the probe response message reaches the condition for determining that the main control board is faulty. If the number of consecutive failures to receive the probe response message is less than N, it is determined that the main control board is not faulty. Conversely, if the number of consecutive failures to receive the probe response message is equal to or greater than N, it is determined that the main control board is faulty.

[0070] Step 104: When it is determined that the main control board is faulty, a reset operation of the baseband board is performed.

[0071] Specifically, if the baseband board determines that the main control board is faulty, it is necessary to automatically perform a reset operation on the baseband board to reduce the interference of the NR cell to the surrounding normal cells and reduce operation and maintenance costs.

[0072] In the above embodiment of the present invention, when the protocol adaptation layer PAM of the standard protocol stack of the main process of the baseband board is started, the main control board information is obtained at intervals of a first preset time length, and a probe message is sent to the main control board based on the main control board information, the probe message including: first main control board information of the main control board receiving the probe message; if the probe response message fed back by the main control board according to the probe message is not detected for N consecutive times, the main control board is determined to be faulty, and when the main control board is determined to be faulty, a reset operation of the baseband board is performed. When the PAM of the standard protocol stack of the main process of the baseband board is started, the baseband board periodically sends a probe message to the main control board, and the baseband board can determine whether the main control board is abnormal based on the number of times the probe response message is not received, and automatically performs a reset operation when it is determined that the main control board is abnormal, so as to reduce interference to the surrounding normal cells and reduce operation and maintenance costs.

[0073] As an optional embodiment, the reset operation includes: executing the baseband board restart command, shutting down the new air interface NR cell, and setting the active antenna processing unit (Active Antenna Unit, AAU) connected to the baseband board to enter sleep mode.

[0074] Specifically, if the baseband board determines that the main control board is faulty, it needs to automatically perform a reset operation of the baseband board, that is, the baseband board needs to execute a baseband board restart command to restart the baseband board. In addition, the baseband board needs to shut down the NR cell and set the AAU connected to the baseband board to sleep mode to avoid the situation where the NR cell is in a hosted state and affects the user access rate of the adjacent normal cell when the main control board fails, thereby reducing interference to the surrounding normal cells and reducing operation and maintenance costs.

[0075] As an optional embodiment, if no detection response message fed back by the main control board according to the detection message is detected for N consecutive times in step 103, before determining that the main control board is faulty, the method further includes:

[0076] Step A1: Detect whether a detection response message fed back by the main control board according to the detection message is received each time the detection message is sent.

[0077] Specifically, after each probe message sent by the baseband board, the baseband master process standard protocol stack (PAM) initiates the probe response reception process, specifically checking whether a probe response message has been received from the main control board. If no probe response message is detected, the process proceeds to step A2. If a probe response message is detected, the main control board is considered normal and continues to periodically send probe messages.

[0078] Step A2: If the probe response message is not received for the first time, the number of times the probe response message is not received is counted until the probe response message is received or the counted number reaches N times.

[0079] Specifically, if no probe response message is detected for the first time, the number of probe messages sent is counted as 1, and the second probe message is sent to detect whether the probe response message is received. If the probe response message is still not received for the second time, the count is increased by 1 to obtain 2, which means that the probe response message has not been detected for two consecutive times. This is repeated until the probe response message is received and the counting ends, or until the counting result reaches N times and the counting ends. Counting can be performed using a probe message counter.

[0080] It should be noted that if the accumulated number of times a probe response message is received is within N times, the count is reset to zero and the probe message continues to be sent periodically.

[0081] As an optional embodiment, the detection message may further include: first baseband board information of the baseband board that sends the detection message and the detection message information type.

[0082] Specifically, the probe message sent by the baseband board may also be filled with a source SFUID, which is used to indicate the first baseband board information of the baseband board that sends the probe message. The first baseband board information includes the location information of the baseband board that sends the probe message. In addition, the probe message information type may also be filled in the probe message sent by the baseband board, which is used to indicate the information type of the sent probe message.

[0083] Optionally, as an optional embodiment, the detection response message may include: the second main control board information for sending the detection response message determined by the main control board based on the first main control board information, the second baseband board information for receiving the detection response message determined by the main control board based on the first baseband board information, and the detection response message information type.

[0084] Specifically, the source SFUID, destination SFUID and probe message information type are filled in the probe message sent by the baseband board. After receiving the probe message, the main control board feeds back the corresponding probe response message based on the source SFUID, destination SFUID and probe message information type filled in the probe message. The source SFUID in the probe response message is the main control board information of the main control board that sends the probe response message, that is, the second main control board information; the destination SFUID in the probe response message is the baseband board information of the baseband board that receives the probe response message, that is, the second baseband board information. The probe response message information type in the probe response message is used to indicate the information type of the probe response message sent, etc.

[0085] It should be noted that the main control board can send a probe response message to the baseband board standard protocol stack PAM through the base station internal communication port number 20000 link.

[0086] As an optional embodiment, the above step A1 detects whether a probe response message fed back by the main control board according to the probe message is received for each sent probe message, including:

[0087] Detecting whether the probe response message is received within a second preset time period for each probe message sent;

[0088] If the probe response message is detected within the second preset time period, determining that the probe response message is received;

[0089] If the probe response message is not detected within the second preset time period, it is determined that the probe response message is not received.

[0090] Specifically, each time the baseband board sends a probe message, the baseband main process standard protocol stack PAM will start the process of receiving the probe response, that is, to detect whether the probe response message fed back by the main control board is received within the second preset time length. If the probe response message is not detected within the second preset time length, it is determined that the probe response message corresponding to the probe message fed back by the main control board has not been received, and a count is performed. If the probe response message is detected within the second preset time length, it is determined that the probe response message corresponding to the probe message fed back by the main control board has been received, and no other operations are performed, and the baseband board continues to send probe messages periodically.

[0091] It should be noted that the second preset duration is the time limit for the baseband board to determine whether the corresponding probe response message has been received after sending each probe message. If the time limit is exceeded, it is determined that the probe response message has not been received. If the probe response message is received within the time limit, it is determined that the probe response message has been received. The second preset duration is a time value less than or equal to the first preset duration and can be set as needed, and is not specifically limited here.

[0092] As an optional embodiment, after the above step 102 sends a detection message to the main control board according to the main control board information, the method further includes:

[0093] If a detection response message fed back by the main control board according to the detection message is detected, the first main control board information is updated according to the detection response message.

[0094] Specifically, if the baseband board standard protocol stack PAM receives and identifies the probe response message returned by the main control board main process standard protocol stack PAM, the baseband board updates the first main control board information based on the source SFUID carried in the probe response message. In other words, the baseband board can identify the location of the main control board based on the source SFUID carried in the probe response message and keep a record of it, providing the main control board's location information for the next periodic probe message, facilitating the filling of the destination SFUID in the probe message, and after determining the main control board's location, clearing the counter for detecting the probe response message to 0, and continuing to execute the next cycle of sending the probe message process.

[0095] The above detection process is described in detail below through a specific embodiment:

[0096] like Figure 2 As shown, the process description of the baseband board:

[0097] Step 21: Construct an OSP header detection message. Specifically, after the baseband board standard protocol stack PAM is started, it independently constructs an OSP header detection message and fills in the source SFUID, destination SFUID, and detection message information type.

[0098] Step 22: Send an OSP header detection message. Specifically, the baseband board calls the link with the base station internal communication port number 20000 to send the detection message to the core where the main control board is located.

[0099] Step 23: Check whether a probe response message has been received. Specifically, after sending a probe message, the response count automatically increases by 1, and the process of detecting a probe response message begins. If the baseband board detects and receives a probe response message returned by the main control board's standard protocol stack, the process proceeds to step 24. If the baseband board does not detect and receive a probe response message returned by the main control board's standard protocol stack, the process proceeds to step 25.

[0100] Step 24: Record the location of the main control board based on the probe response message and reset the count. Specifically, if the baseband board standard protocol stack receives a probe response message returned by the main control board standard protocol stack, it records the location of the main control board based on the probe response message, resets the count, and continues to periodically construct and send probe messages.

[0101] Step 25 determines whether the number of consecutive failures to receive a probe response message has reached N. Specifically, if the baseband board standard protocol stack has not received the probe response message returned by the main control board standard protocol stack, it periodically sends probe messages and counts them to determine whether the number of consecutive failures to receive a probe response message has reached N. If the number of consecutive failures to receive a probe response message has not reached N, the baseband board continues to periodically send probe messages, i.e., the baseband board continues to execute the next probe process, i.e., returns to step 21 above. If the number of consecutive failures to receive a probe response message has reached N, proceed to step 26.

[0102] Step 26: Reset the baseband board. If the number of probe response messages not received reaches N times in a row, the baseband board standard protocol stack determines that the main control board has failed or is not in place. The baseband board standard protocol stack resets the baseband board, restarting the baseband board, autonomously shutting down the NR cell, and setting the AAU connected to the baseband board to sleep mode to minimize the impact on normal cells.

[0103] like Figure 3 As shown, the process description of the main control board:

[0104] Step 31: Receive and identify an OSP header detection message. Specifically, the main control board standard protocol stack PAM receives and identifies the OSP header detection message sent by the baseband board standard protocol stack PAM, triggering a detection response process.

[0105] Step 32: Construct an OSP header probe response message. Specifically, in the probe response process, the received OSP header probe message is updated, that is, the source SFUID and destination SFUID are updated, and the probe message information type is updated to the probe response message information type, thereby forming an OSP header probe response message.

[0106] Step 33: Send a probe response message. Specifically, the OSP header probe response message calls the link with the base station internal communication port number 20000 to send the probe response message to the core where the main process of the baseband board of the base station is located.

[0107] In summary, in the above-described embodiments of the present invention, the baseband board periodically sends probe messages to the main control board, and the main control board returns a probe response message based on the probe message. If the baseband board does not receive the probe response message, it continues to perform probes and determines whether the detection threshold N has been reached. This allows the main control board to be determined to be faulty. In the event of a fault, the baseband board can be reset to prevent the AAU in a cell from interfering with user access in normal cells. Furthermore, when the base station main control board changes slots, it can send slot information to the baseband board via a probe response message.
