[0045] The data acquisition method provided in the embodiment of the present application can be executed in a terminal, a computer or a similar test platform. Taking running on a terminal as an example, Figure 1 is a hardware structure block diagram of a terminal according to a data acquisition method of an embodiment of the present application. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102, and memory 104 for storing data. Processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. Optionally, the terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0046] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer programs corresponding to the data probe points in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, to implement the above-mentioned method.

In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0048] The various technologies described in the embodiments of this application can be used for the maintenance and analysis of base stations, micro base stations and pico base stations. Taking the application to base stations as an example, Figure 2 FIG. 1 shows a schematic diagram of the hardware structure of a base station provided in an embodiment of the present application. Figure 2 As shown, the base station 20 includes a baseband processing unit 201 and a remote radio unit (RRU) 202. Among them, the physical layer 201a of the baseband processing unit 201 will involve message communication with other modules during the implementation process, such as communication between the physical layer 201a and the upper layer (such as the protocol stack 201b), and communication between the baseband processing unit 201 and the remote radio unit 202, so the maintenance of the physical layer 201a is particularly important. Most of the related technologies use a printing method to store the base station data related to the physical layer during the operation of the base station into a specified data format, which is called log information (log), and then download the log information of the base station to the local by setting a method. This method of obtaining base station data is not only slow, but also increases the link overhead of the physical layer. Since the physical layer processes data in the service link, the additional link overhead will cause the real-time performance of the physical layer processing data to be affected.

[0049] Since the physical layer has strict timing requirements, based on this, the embodiment of the present application can reduce the time to obtain base station data from the physical layer and ensure the real-time processing of data by the physical layer. The obtained base station data can be used to analyze the working state of the physical layer, thereby determining the operating state of the base station.

[0050] Before describing the method of the embodiment of the present application, the improvement principle of the method is first introduced.

[0051] From the above introduction, it can be known that the physical layer is responsible for the data processing task. Specifically, the physical layer can perform transmission processing on the data, and the business module inside the physical layer can modulate, calculate, and analyze the data. Therefore, the data on the nodes participating in the processing task of the physical layer is saved as base station data, and the working status of the physical layer can be analyzed. In the related technology, the physical layer processes data through one or more business threads, and does not directly capture data for maintenance during the processing process. This is because the physical layer has strict timing requirements. If the physical layer business thread uses shared memory to simultaneously execute data processing and data capture, it will affect the process of processing data by the business thread, such as affecting the time of sending and receiving messages. Therefore, the embodiment of the present application implements the setting of data probe points at the nodes that process data inside the physical layer. The data probe points save the base station data and notify other threads to capture data from the address of the data probe points. This will not affect the process of processing data by the original business threads of the physical layer, and the speed of obtaining data is also faster.

[0052] The following is an example of a baseband processing unit having the above-mentioned components to illustrate the method provided by an embodiment of the present application. In this method, the baseband processing unit runs at least a first thread and a second thread at the same time, wherein the first thread is equivalent to one or more business threads introduced above, that is, the first thread can be a business thread, or it can be a thread pool including multiple business threads. The first thread is used to process base station data sent and received by the physical layer of the baseband processing unit. The second thread is different from the first thread. The second thread is a thread (or a number grabbing thread) in the baseband processing unit for executing data acquisition alone, that is, the second thread does not participate in the physical layer's processing tasks for base station data. In addition, the second thread can be started after the base station is turned on, or it can be started in response to an operation and maintenance instruction.

[0053] The method includes Figure 3 Steps S301 to S303 are shown.

[0054] Step S301: When the first thread executes a processing task for base station data, a data probe point is called to store the base station data.

[0055] The execution of the processing task may be understood as the physical layer transmitting (receiving or sending) and / or modulating and demodulating base station data through the first thread.

[0056] Specifically, if the physical layer sends a first message to the protocol stack through the first thread, the base station data includes the first message, and the execution of the processing task can be understood as the first thread sending the base station data. If the physical layer receives a second message sent by the radio remote unit through the first thread, the base station data includes the second message, and the execution of the processing task can be understood as the first thread receiving the base station data. If the physical layer modulates or demodulates the first thread to obtain a third message, the base station data includes the third message, and the execution of the processing task can be understood as the first thread modulating or demodulating the base station data.

[0057] In this step, the triggering time for the physical layer to store the base station data can be preset. For example, but not limitation, the triggering time for calling the data probe point to store the base station data can be when the physical layer sends the base station data to the protocol stack or the radio remote unit through the first thread, and the physical layer detects that the transmission interface (such as CPRI or eCPRI port) is called; or when the physical layer receives the base station data sent by the protocol stack or the radio remote unit through the first thread, the physical layer detects that the transmission interface is called; or when the physical layer executes the internal algorithm modulation or demodulation to obtain the output result (i.e., the base station data), the physical layer detects that the channel modulation and demodulation module is called.

[0058] As an example, the physical layer stores base station data by deploying a network packet capturer. Taking the network packet capturer as a wireshark tool, the wireshark tool is constructed by running a program package corresponding to the wireshark tool on a terminal such as a PC, and data detection points are deployed at each node through the wireshark tool. When it is detected that the first thread processes the base station data, the physical layer calls the wireshark tool through the first thread to store the base station data, so as to obtain the base station data from the wireshark tool later.

[0059] It is worth mentioning that in this step, the network packet grabber is deployed in the physical layer, which can capture both the messages sent and received by the physical layer and the messages output by the internal processing signal of the physical layer. Therefore, the base station data obtained by the network packet grabber is more informative, and the maintenance and measurement results obtained by analyzing the base station data will be more accurate.

[0060] In addition, this step detects the physical layer sending and receiving messages or modulating and demodulating messages, and then stores the messages in real time. In the related art, the operation and maintenance instructions are detected before the messages are obtained in the form of printing. In comparison, this step obtains messages faster and in real time.

[0061] Step S302: Send an indication message to the second thread through the first thread, where the indication message includes location information of the data probe point.

[0062] The indication information includes a semaphore, that is, the first thread and the second thread can interact by sending and receiving semaphores. Specifically, the physical layer posts a semaphore (or sends a semaphore) to the second thread of the physical layer through the first thread to instruct the second thread to perform an operation of obtaining base station data from the address where the first thread stores base station data. The second thread can always wait for the semaphore (or wait for the semaphore). When the second thread receives the semaphore, it can perform the operation indicated by the semaphore. For details, please refer to the introduction of step S303 below.

[0063] It can be understood that the indication information carries the address space to indicate the location of the base station data. Just because the first thread stores the base station data in step S301, the address space carried by the indication information can be the address space for the first thread to store the base station data. Compared with directly sending the address for the interaction between the physical layer and the transmission target (such as the service stack) to the second thread, the method of sending the address space for storing the base station data in the first thread to the second thread not only avoids interrupting the processing sequence of the first thread, ensures the real-time nature of the first thread processing the interaction message between the physical layer and the transmission target, but also avoids the second thread and the first thread processing a piece of memory at the same time, which affects the business thread data processing. In this embodiment, the address space is the location information of the data probe point. In some other feasible embodiments, the address space can be the location for storing the base station data in the first thread, wherein the address space is different from the node location of the first thread processing task, so it will not affect the first thread processing task.

[0064] Step S303: In response to the instruction message, control the second thread to obtain base station data from the data probe point, wherein the base station data in the second thread is used for external transmission.

[0065] Among them, sending the base station data outward includes storing the base station data in the memory, or sending the base station data to an external server, etc. It can be understood that the base station data in the second thread is used for outward transmission, so that when data needs to be sent outward, the base station data can be obtained from the second thread in real time, and the outward transmission step is executed in the second thread, so it will not affect the real-time processing task of the first thread.

[0066] The following continues to explain this step by taking the indication information including a semaphore as an example. Since the second thread of the physical layer maintains communication with the first thread, after the first thread sends the semaphore to the second thread, the second thread receives the semaphore and can execute the operation of obtaining base station data from the data probe point based on the address space carried by the semaphore.

[0067] In the embodiment of the present application, the base station data source is messages related to the physical layer, including messages sent and received via the physical layer, messages modulated and demodulated within the physical layer, etc. The base station data is parsed and analyzed to obtain the working state of the physical layer, and the base station can be maintained and tested according to the working state of the physical layer.

[0068] By way of example and not limitation, the base station data includes first base station data transmitted between the physical layer of the baseband processing unit and the protocol stack of the baseband processing unit, second base station data transmitted between the baseband processing unit and the radio frequency remote unit through the physical layer, and / or third base station data processed by a service module within the physical layer, wherein the transmission may be one or more of sending, receiving, issuing, and reporting, and the present application does not impose any limitation on this.

[0069] More specifically, the first base station data includes: one or more of the configuration parameters sent by the protocol stack to the physical layer and the demodulation results reported by the physical layer to the protocol stack. The second base station data includes: one or more of the downlink air interface data sent by the baseband processing unit to the radio remote unit through the CPRI or eCPRI port and the uplink air interface data sent by the radio remote unit to the baseband processing unit through the CPRI or eCPRI port. The third base station data includes: the uplink pusch channel output data output by the channel estimation module inside the physical layer and the downlink pdsch channel output data output by the pdsch channel modulation module inside the physical layer.

[0070] In the embodiment recorded in the above steps S301 to S303, a second thread for maintenance and measurement is provided inside the physical layer, and the second thread and the first thread keep running, and the first thread is responsible for processing the base station data sent and received by the physical layer of the baseband processing unit. When the first thread sends and receives base station data and modulates and demodulates base station data, it will call the data probe point to save the base station data. The first thread will send an indication message to the second thread to instruct the second thread to grab the base station data from the data probe point. In this embodiment, the data probe point is set on the service link of the physical layer, such as the interface between the physical layer and the transmission target, the modem module inside the physical layer, etc. Whenever base station data is generated in the service link, the first thread calls the data probe point to store the base station data, which not only ensures the real-time acquisition of base station data, but also does not affect the service processing of the base station data by the first thread. Therefore, this embodiment solves the technical problem that the acquisition of base station data related to the physical layer in the prior art cannot ensure the real-time processing of data by the physical layer.

[0071] In some embodiments, the number of data probe points is set according to the number of nodes, and each node corresponds to at least one data probe point. Figure 4 As shown, the above step S301 includes steps S401 to S402.

[0072] Step S401: When it is detected that the first thread is processing a task on a node, the first thread is controlled to send a call instruction to a data probe corresponding to the node.

[0073] Step S402: In response to the calling instruction, the data probe point is called to store the base station data on the node.

[0074] Specifically, if the physical layer transmits the first base station data at the first node, a first call instruction is sent to the first data probe corresponding to the first node, and in response to the first call instruction, the first data probe stores the first base station data. If the physical layer transmits the second base station data at the second node, a second call instruction is sent to the second data probe corresponding to the second node, and in response to the second call instruction, the second data probe stores the second base station data. If the physical layer transmits the third base station data at the third node, a third call instruction is sent to the third data probe corresponding to the third node, and in response to the third call instruction, the third data probe stores the third base station data. The first node may be an interface for transmitting base station data between the physical layer and the protocol stack, the second node may be an interface for transmitting base station data between the physical layer and the radio remote unit, and the third node may be a service module inside the physical layer.

[0075] The node includes an interface for transmitting base station data between the physical layer and the protocol stack, an interface for transmitting base station data between the physical layer and the radio remote unit, and / or a service module inside the physical layer. Exemplarily, a first data probe point is set at the transmission interface between the physical layer and the radio remote unit (such as a CPRI or eCPRI port); or, a second data probe point is set after the channel estimation function inside the physical layer; or, a third data probe point is set in the pdsch channel modulation module inside the physical layer; or, a fourth data probe point is set at the transmission interface between the physical layer and the protocol stack (such as the Layer 1 or Layer 2 interface in LTE). The first data probe point, the second data probe point, the third data probe point, and the fourth data probe point can store the messages interacting between the physical layer and the protocol stack after receiving the call instruction of the first thread. The number of data probe points corresponds to the number of nodes, so that the physical layer can obtain the base station data of each service processing node of the physical layer, so that the obtained base station data contains richer and more comprehensive content. In addition, when adding services at the physical layer, the required data information can be captured by adding data probe points at the nodes of the service link; or, the base station information of the service link can be no longer captured by deleting data probe points at the nodes of the service link. By setting data probe points, the amount of operations is simplified, the data acquisition efficiency is higher, and the maintenance efficiency is also higher.

[0076] In some of the embodiments, continue to refer to Figure 4 , the above step S302 includes:

[0077] Step S403: After the data probe stores the base station data, the first thread controls the data probe to send an indication message to the second thread, and the indication message is transmitted between the data probe and the second thread in the form of a semaphore.

[0078] Specifically, threads can interact with each other through semaphores. The data probe point is arranged in the first thread, so the first thread can control the data probe point to send a semaphore to the second thread to instruct the second thread to capture the base station data.

[0079] The present application also provides a base station maintenance method, such as Figure 5 As shown, the method includes steps S501 to S503.

[0080] Step S501: Acquire base station data from the second thread.

[0081] Among them, what is obtained from the second thread is the base station data captured based on the processing timing of the physical layer. Therefore, the base station data is strongly correlated with the timing of the physical layer. The physical layer will locate and analyze the problem based on the obtained base station data and the processing timing inside the physical layer.

[0082] In some embodiments, step S501 includes: establishing a communication connection with a baseband processing unit; and receiving base station data sent by the baseband processing unit through the second thread when the second thread obtains the base station data from the first thread.

[0083] In this embodiment, a communication connection is established between the baseband processing unit and the server device, so that after the second thread captures the base station data, the base station data is sent to the server device in real time. By capturing the base station data online in real time, the maintenance efficiency is improved.

[0084] In some of the embodiments, step S501 includes: acquiring base station data stored in a log form from a memory of a baseband processing unit, wherein the base station data is cached in the memory after being acquired from a data probe point by a second thread.

[0085] In this embodiment, the second thread stores the base station data in the memory of the baseband processing unit, so that the operator can view the base station data offline.

[0086] Step S502: parse the base station data according to the parsing rules corresponding to the preset communication protocol to obtain parsing information.

[0087] Continuing to use the wireshark tool as an example, in order to be able to use the wireshark tool to display and view the acquired base station data, it is necessary to carry out secondary development of the parsing function of wireshark. Here it is necessary to define the message protocol for capturing data (equivalent to the above-mentioned base station data), package the data according to the predefined message protocol inside the baseband processing unit, and then send it to the wireshark tool. The wireshark tool will carry out secondary tool development based on the predefined message protocol to parse the acquired data into a specified format. Exemplarily, the predefined data format is:

[0088] typedef struct

[0089] {

[0090] uint32_t MessageType;

[0091] uint32_t MessageLen;

[0092] uint32_t NumMessage;

[0093] }WIRESHARK_MSG_FORMAT;

[0094] When capturing data, the data and messages will be packaged according to the above protocol. Different data and messages have different message types. When developing the wireshark tool, it will judge and parse according to the message format.

[0095] It should be noted that when the wireshark tool captures network port data packets, it will capture all data flows of the network port with the IP set. In order to accurately filter out the data packets sent by the baseband processing unit (equivalent to the above-mentioned base station data), it is necessary to specify the port number (or port number) for distinction. For example, if the data packets sent by the baseband processing unit to the IP network port are defined as port number 4567, then when developing the parsing function of the wireshark tool, it is necessary to use port number 4567 for filtering, so that all data packets with port number 4567 will be filtered out, and then the data packets will be parsed according to the preset interface protocol.

[0096] Step S503: Determine the working state of the physical layer of the baseband processing unit according to the parsed information.

[0097] Specifically, after parsing the base station data, the operating status of the unit generating the base station data and the parameter value of the status identifier of the message content can be obtained. Exemplarily, the parameter value corresponding to the operating status of the physical layer is set to phyState, and the operating status of the base station is determined according to the value of phyState, such as phyState = 0, indicating that the physical layer is in an idle state; phyState = 1, indicating that the physical layer is in a parameter configuration state; phyState = 2, indicating that the physical layer is in an operating state; phyState = 3, indicating that the physical layer is in an error state.

[0098] The base station maintenance and measurement method provided in the embodiment of the present application is described and illustrated by means of specific examples below.

[0099] First, create a thread at the physical layer to capture io data and info information. For example, the thread name is ioInfoThread. In this thread, the ioInfo_init() function is first initialized to initialize variables and build the wireshark message header. During the initialization process, it is necessary to create a data storage buffer size (or cache size). This parameter can be used as an input variable to provide input parameters for users to configure. This thread is equivalent to the second thread mentioned above.

[0100] Then use the defined save_macphy_msg() function as a probe point (equivalent to the data probe point described above), and call this function at the nodes where the protocol stack and the physical layer send and receive data, so that the business code can save data in the processing flow, so that the second thread can capture the message between the physical layer and the high layer. For example, when the physical layer receives a high-level message, the probe point function can be called to capture the message. Similarly, when the physical layer reports the demodulation result to the high layer, the probe point can also be called to save the message. Among them, the message includes the configuration parameters sent from the high layer to the physical layer, and the demodulation result reported by the physical layer to the high layer. This message is equivalent to the first base station data mentioned above.

[0101] Alternatively, use the save_ether_data() function to obtain the air interface data between the BBU and the RRU. When the physical layer packages the data and sends it to the RRU according to the eCPRI protocol group, this probe point can be added to capture the downlink data sent by the physical layer. When the physical layer receives the uplink data packet through the eCPRI port, the probe point can be called to save the uplink data sent by the RRU to the BBU. This message is equivalent to the second base station data mentioned above.

[0102] Alternatively, use the save_phy_data() function to obtain the maintenance information during the internal processing of the physical layer, including the output results of each function in the physical layer processing process. For example, it includes the data of each node in the physical layer processing the downlink channel and the node data in the physical layer processing the uplink channel. In the function, a probe point will be provided for the physical layer to save data according to the processing requirements of each channel, so that the information of each node processed in the physical layer can be obtained in real time. In the internal processing flow of the physical layer, set the probe point in advance to set the data to be saved. This node information is equivalent to the third base station data mentioned above.

[0103] After the second thread captures the data, the data can be displayed online in real time. Exemplarily, a udp_sevice() function can be created to enable the baseband processing unit and the network port to communicate via udp, with the purpose of sending the ioInfo data (equivalent to the base station data) captured in the baseband processing unit to the server computer in real time, and the ioInfo data sent by the baseband processing unit can be obtained through the network port of the server computer. As an example, an IP port can be reserved, and the IP port will be set according to the operator's computer, so that network communication between the baseband processing unit and the server computer can be achieved. The ioInfo data captured by the baseband processing unit can be obtained by an external server computer in real time.

[0104] Alternatively, when offline storage is required, the base station data acquired by the data probe point can be saved in the memory of the baseband processing unit, and polled and stored according to the pre-set buffer size. When the base station data cached in the memory needs to be saved in the log, the save command can be entered to save the cached base station data in the log according to the preset pcap file format.

[0105] The operator can download the log to the local computer and use the wireshark tool to view and analyze it. For details, please refer to the description of step S502, which will not be repeated here.

[0106] In summary, the base station maintenance method provided by the embodiment of the present application creates a separate capture thread inside the BBU to avoid the time-consuming capture affecting the timing of the normal business thread. In the capture thread inside the BBU, capture functions of different messages are created according to the needs of the capture, and the messages include protocol stack and physical layer interaction messages, data interaction messages between BBU and RRU, and maintenance data messages inside the physical layer. Of course, other message contents can also be defined in the capture thread as needed. The defined capture function can be used as a probe point for the business process to call, and the node that needs to be captured in the business process can directly call the probe point to save the message to the capture thread. The capture thread will package the message according to the predefined data format, which can be stored in the system memory or sent online to the network port. The external server will use the wireshark tool to capture the network port data, parse it according to the parsing rules corresponding to the preset communication protocol, and obtain the parsing information, so as to determine the working state of the physical layer. The data obtained by this method is faster and more real-time, and will not affect the business link inside the physical layer, so the efficiency of maintenance is greatly improved.
