Background
In the process of communication data transmission, in order to monitor the accuracy of data transmission, the stability of communication quality is ensured, the transmitted data needs to be checked, whether the data transmission process is abnormal or not is determined in time, and abnormal positioning is performed.
In the art, anomaly localization is typically performed by parsing cyclic redundancy check codes (CRCs, cyclic Redundancy Check). The CRC has a data transmission error detection function, and by performing polynomial calculation on the data and attaching the obtained result to the rear of the frame, the receiving device also executes a similar algorithm, and if the CRC check is erroneous, a block error rate (Bler, block Error Ratio) occurs, so that an anomaly analysis is performed according to whether or not the Bler is present.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, a flowchart of specific steps of an anomaly locating method according to an embodiment of the present invention is shown.
Step 101, a preset grabbing condition is issued to a baseband processing unit BBU, so that when the BBU determines that the preset grabbing condition is met, an active antenna unit AAU is triggered to grab time domain data through a first interface.
Wherein, the preset grabbing condition comprises: at least one of data capture identification, data capture time slot and capture time length.
The present invention discloses an abnormality positioning method, which is applied to a simulation platform, simulates a data transmission process through data simulation, and determines an abnormal side with error code according to a simulation result.
In the embodiment of the invention, the preset grabbing condition can be set through the simulation platform, and when the preset grabbing condition is met, the BBU is controlled to trigger the AAU to grab the time domain data through the first interface, specifically, when the data grabbing mark is the target value, the BBU is controlled to send the grabbing instruction to the AAU, the grabbing instruction comprises the preset grabbing condition, and after the grabbing instruction is received by the AAU, the time domain data is grabbed according to the preset grabbing condition.
Optionally, the AAU grabs corresponding time domain data according to the data grabbing time slot and the grabbing time length. The data grabbing time slot indicates the starting position of the time domain data to be grabbed in the data frame, the grabbing time length indicates the data length of the time domain data to be grabbed, and the AAU can determine which time domain data to be grabbed according to the data grabbing time slot and the grabbing time length, so that the accuracy of data grabbing is guaranteed.
Step 102, obtaining a scheduling message and a base station configuration parameter corresponding to the preset number of grabbing conditions sent by the BBU through a second interface.
In the embodiment of the invention, when a preset grabbing condition is met, for example, a preset grabbing time is reached, or a data grabbing mark is a target value, besides triggering an AAU to grab time domain data, the BBU also acquires a scheduling message and a base station configuration parameter corresponding to the preset grabbing condition at the same time, wherein the data transmission direction can be determined according to the scheduling message, such as uplink transmission or downlink transmission; the base station configuration parameters indicate corresponding data transmission conditions when transmitting the time domain data captured by the AAU.
In the embodiment of the invention, the information interaction between the network elements is realized through the corresponding data transmission interfaces, thereby avoiding the time delay caused by processing the data format according to the communication protocol between the different network elements in the data transmission process and improving the data transmission efficiency. The BBU sends the scheduling message and the base station configuration parameters to the simulation platform through the second interface, so that the simulation platform can simulate data according to the scheduling message and the base station configuration parameters and simulate a data transmission process.
And step 103, acquiring the time domain data grabbed by the AAU through a third interface.
After the AAU finishes grabbing time domain data, the grabbed time domain data are transmitted to the simulation platform through the third interface so as to be used for data simulation by the simulation platform.
And 104, performing data simulation according to the scheduling message, the base station configuration parameters and the time domain data to obtain a simulation result.
In combination with the foregoing, the simulation platform can simulate the data transmission process completely by data simulation according to the scheduling message and the base station configuration parameter acquired from the BBU and the time domain data acquired from the AAU, including the decoding process of the simulated time domain data.
And 105, determining an abnormal side where the error code occurs according to the simulation result.
As known from the combining step 104, in the embodiment of the present invention, the simulation platform simulates the data transmission process according to the obtained scheduling message, the base station configuration parameter and the time domain data, and simulates the decoding process of the time domain data, thereby judging the abnormal side where the error code occurs based on the simulation result.
Specifically, under the condition that error codes exist actually, CRC decoding simulation is carried out on the captured time domain data; if the simulation result does not have error codes, determining an abnormal side with error codes as a BBU side; if the simulation result has error codes, determining the abnormal side with the error codes as the UE side.
In combination with the foregoing, in the embodiment of the present application, the simulation platform simulates the data transmission condition based on the obtained scheduling message and the base station configuration parameter, that is, when performing data simulation, the time domain data is in the ideal data transmission condition, which is equivalent to performing data transmission under the condition that the preset condition is that no abnormality exists on the BBU side, if the simulation result has no error code, the simulation result is inconsistent with the actual situation, and the preset condition is illustrated as being incorrect, that is, the BBU side has an abnormality; if the simulation result has error codes and is consistent with the actual situation, the preset condition is correct, namely, the BBU side has no abnormality, and because the time domain data grabbed by the AAU is the actually transmitted data, when the BBU side and the UE side carry out data transmission, the BBU side has no abnormality, the transmitted time domain data is consistent with the actually transmitted data, and under the condition that the simulation result is inconsistent with the actual situation, the UE side has the abnormality can be determined.
In summary, the scheduling information, the base station configuration parameters and the time domain data are directly summarized to the simulation platform through different interfaces to perform data simulation, and then the abnormal side with the error code is determined according to the simulation result, so that time delay caused by processing data formats according to communication protocols among different network elements in the data transmission process is avoided, the data simulation can be directly and automatically performed after the data is acquired, manual operation is not needed, and the abnormal positioning efficiency is improved.
Example two
Referring to fig. 2, a flowchart of specific steps of an anomaly locating method according to a second embodiment of the present invention is shown.
Step 201, a preset grabbing condition is issued to a baseband processing unit BBU, so that when the BBU determines that the preset grabbing condition is met, an active antenna unit AAU is triggered to grab time domain data through a first interface.
The present invention discloses an abnormality positioning method, which is applied to a simulation platform, simulates a data transmission process through data simulation, and determines an abnormal side with error code according to a simulation result.
In the embodiment of the invention, the simulation platform sets the preset grabbing condition, and when the preset grabbing condition is met, the BBU is controlled to trigger the AAU to grab the time domain data through the first interface, specifically, when the data grabbing mark is the target value, the BBU is controlled to send the grabbing instruction to the AAU, the grabbing instruction comprises the preset grabbing condition, and after the grabbing instruction is received by the AAU, the time domain data is grabbed according to the preset grabbing condition.
Wherein, the preset grabbing condition comprises: at least one of data capture identification, data capture time slot and capture time length.
Optionally, the AAU grabs corresponding time domain data according to the data grabbing time slot and the grabbing time length. The data grabbing time slot indicates the starting position of the time domain data to be grabbed in the data frame, the grabbing time length indicates the data length of the time domain data to be grabbed, and the AAU can determine which time domain data to be grabbed according to the data grabbing time slot and the grabbing time length, so that the accuracy of data grabbing is guaranteed.
Step 202, obtaining a scheduling message and a base station configuration parameter corresponding to the preset number of grabbing conditions sent by the BBU through a second interface.
In the embodiment of the invention, when a preset grabbing condition is met, for example, a preset grabbing time is reached, or a data grabbing mark is a target value, besides triggering an AAU to grab time domain data, the BBU also acquires a scheduling message and a base station configuration parameter corresponding to the preset grabbing condition at the same time, wherein the scheduling message indicates a data transmission direction, such as uplink transmission or downlink transmission; the base station configuration parameters indicate corresponding data transmission conditions when transmitting the time domain data captured by the AAU.
In the embodiment of the invention, the information interaction between the network elements is realized through the corresponding data transmission interfaces, thereby avoiding the time delay caused by processing the data format according to the communication protocol between the different network elements in the data transmission process and improving the data transmission efficiency. The BBU sends the scheduling message and the base station configuration parameters to the simulation platform through the second interface, so that the simulation platform simulates a data transmission process according to the scheduling message and the base station configuration parameters.
And step 203, acquiring the time domain data grabbed by the AAU through a third interface.
After the AAU finishes time domain data grabbing, the grabbed time domain data is transmitted to the simulation platform through the third interface so as to be used for data simulation by the simulation platform.
And 204, performing data simulation according to the scheduling message, the base station configuration parameters and the time domain data to obtain a simulation result, wherein the simulation result comprises a Cyclic Redundancy Check (CRC) decoding result of the time domain data.
In the embodiment of the invention, the simulation platform simulates the data transmission process according to the obtained scheduling message, the base station configuration parameter and the time domain data to obtain a simulation result. Specifically, the CRC decoding process of the transmitted time domain data may be simulated, and then the simulation result includes the CRC decoding result of the time domain data.
Step 205, determining the transmission type of the time domain data according to the scheduling message.
And step 206, determining the grabbing position of the time domain data according to the preset grabbing condition.
Step 207, determining an abnormal side where an error code occurs according to the transmission type, the capturing position and the decoding result.
The transmission type represents the data transmission direction of the time domain data and comprises uplink transmission and downlink transmission; the grabbing position represents the position of the grabbed time domain data in the data transmission process, and comprises an AAU outlet and an AAU inlet.
In combination with the foregoing step 201, it can be seen that the current network architecture is composed of a core network, a BBU, an AAU and a UE, and the data transmission process is different for different transmission types. Specifically, for uplink transmission, the UE sends a scheduling request to the BBU, the BBU responds to the scheduling request and sends a scheduling message to the UE, the UE sends data to the AAU according to the received scheduling message, and the AAU performs time-frequency conversion on the received data and then sends time-domain data to the BBU; for downlink transmission, the BBU performs scheduling and transmits data to the AAU, and the AAU performs time-frequency conversion and then transmits time domain data to the UE.
As can be seen from the above description, for different transmission types, under the condition that the data capturing positions are the same, the sender and the receiver of the time domain data are also different, and further, according to the decoding result of the captured time domain data, the abnormal sides where the error code occurs are determined to be different, so in the embodiment of the invention, according to the transmission types and the different capturing positions of the time domain data, the decoding result is correspondingly analyzed, and the abnormal sides where the error code occurs are determined, thereby reducing the range of abnormal positioning and improving the abnormal positioning efficiency.
Optionally, when the transmission type is uplink transmission, the step of determining an abnormal side where an error code occurs according to the transmission type, the capturing position and the decoding result includes: if the grabbing position is the AAU outlet and the decoding result is the first target value, determining that the abnormal side with the error code is the BBU side; or if the decoding result is the second target value when the grabbing position is the AAU entry, determining the abnormal side with the error code as the User Equipment (UE) side.
The embodiment of the invention determines the abnormal side with the error code through simulation under the condition that the error code exists in the actual transmission data. If the decoding result is the first target value, the fact that the grabbed time domain data have no error code is indicated; and if the decoding result is the second target value, indicating that the bit error exists in the captured time domain data.
In combination with the foregoing, when the transmission type is uplink transmission, after time-frequency conversion is performed on the data sent by the UE through the AAU, the data is sent to the BBU by the AAU, if the decoding result when the grabbing position is the exit of the AAU is a first target value, which indicates that the data has no error before reaching the BBU, that is, the UE side and the AAU side have no error, however, the actual transmission data has an error, only the BBU side may have an error, so that it is determined that the abnormal side is the BBU side.
Similarly, when the transmission type is uplink transmission, if the decoding result when the grabbing position is the AAU entry is the second target value, it indicates that the data has an error code before reaching the AAU, and it can be determined that the abnormal side where the error code occurs is the UE side.
Optionally, when the transmission type is downlink transmission, the step of determining an abnormal side where an error code occurs according to the transmission type, the capturing position and the decoding result includes: if the grabbing position is the AAU entry and the decoding result is the second target value, determining that the abnormal side with the error code is the BBU side; and if the grabbing position is the AAU outlet and the decoding result is the first target value, determining the abnormal side with the error code as the UE side.
In combination with the foregoing, when the transmission type is downlink transmission, the BBU sends data to the AAU, and then the AAU sends the data to the UE, if the decoding result when the grabbing position is the AAU entry is a second target value, which indicates that the data has an error code before reaching the AAU, so that it can be determined that the abnormal side is the BBU side; similarly, if the decoding result when the grabbing position is the AAU exit is the first target value, which indicates that the data has no error before reaching the UE, that is, the data has no error on the BBU side and the AAU side, but the actual transmission data has an error, only the UE side has an error, so that the abnormal side is determined to be the UE side.
Optionally, when the transmission type is uplink transmission or downlink transmission, the step of determining an abnormal side where an error code occurs according to the transmission type, the capturing position and the decoding result includes: and if the decoding result when the grabbing position is the AAU outlet is the second target value and the decoding result when the grabbing position is the AAU inlet is the first target value, determining that the abnormal side with the error code is the AAU side.
In combination with the foregoing, if the decoding result at the time of the access position being the AAU exit is the second target value, it indicates that the error code occurs when the data is transmitted from the AAU, and because the decoding result at the time of the access position being the AAU entry is the first target value, it indicates that the error code does not occur before the data arrives at the AAU, that is, the error code does not exist when the data is transmitted into the AAU, and the error code occurs when the data is transmitted out of the AAU, so that whether the transmission type is uplink or downlink, it can be determined that the abnormal side where the error code occurs is the AAU side.
In summary, the scheduling information, the base station configuration parameters and the time domain data are directly summarized to the simulation platform through different interfaces to perform data simulation, and then the abnormal side with the error code is determined according to the simulation result, so that time delay caused by processing data formats according to communication protocols among different network elements in the data transmission process is avoided, the data simulation can be directly and automatically performed after the data is acquired, manual operation is not needed, and the abnormal positioning efficiency is improved. In addition, the invention correspondingly analyzes the decoding result according to the transmission type and the grabbing position of the time domain data, and determines the abnormal side with error codes, thereby reducing the range of abnormal positioning and further improving the efficiency of abnormal positioning.
