Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. 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.
Fig. 1 is a schematic diagram of a processing flow of the RRU for communication data provided by the present embodiment, referring to fig. 1, the process of transmitting uplink and downlink data by the RRU is respectively: (1) uplink processing flow: the uplink air interface time domain data is transmitted to an uplink front end module ul_ aiu _inf through an electric interface module electric_inf and a channel module data_path_inf, the uplink front end module ul_ aiu _inf is converted into frequency domain data through FFT (fast Fourier transform ), and then a data packet header is added through an ul_iq_hub module and then transmitted to an optical interface; the optical port comprises a CPRI (Common Public Radio Interface, universal public radio interface) protocol side and a GTY physical side, and the frequency domain data is sent to a baseband processing unit BBU (Building Base band Unite, baseband processing unit) side through an optical fiber after being re-packetized according to the CPRI. (2) downstream processing flow: the base station unit transmits the frequency domain data to the RRU radio frequency unit, and transmits the frequency domain data to the downlink beam shaping module dlpro _inf after unpacking the frequency domain data through the optical port, and transmits the frequency domain data to the access module after converting the frequency domain data to the time domain data, and finally the radio frequency antenna transmits the time domain data to the radio frequency antenna through the electric port according to the CPRI protocol. When a system link fails, the fault location is performed on the basis of the RRU shown in fig. 1, which is troublesome on one hand, and even cannot be located due to environmental problems, on the other hand, the acquired data size is small, and effective fault information cannot be acquired through a small number of data files.
In order to solve the above technical problem, fig. 2 is a flow chart of a data extraction method for positioning a transmission link failure according to the present embodiment, including:
step 201: if a first upgrade enabling command for extracting preset type data from a target functional module is received, determining a data source for extracting the preset type data from the target functional module according to the first upgrade enabling command, wherein the data source is used as a first data source, and extracting the preset type data through the first data source;
step 202: if a second upgrade enabling command for extracting the frequency domain data is received, determining a second data source for extracting the frequency domain data according to the second upgrade enabling command, and extracting the frequency domain data through the second data source;
Step 203: if a third upgrade enabling command for extracting the time domain data is received, determining a third data source for extracting the time domain data according to the third upgrade enabling command, and extracting the time domain data through the third data source;
the extracted preset type data, frequency domain data and/or time domain data are used for analyzing transmission link faults.
The method provided by the embodiment is executed by the RRU, specifically, when a first upgrade enabling command is received, extracting preset type data from the first data source through a preset soft logic extracting module. And when a second lifting enabling command is received, extracting frequency domain data from the second data source through the frequency domain lifting module. And when a third lifting enabling command is received, extracting time domain data from the third data source through the time domain lifting module.
Fig. 3 is a schematic diagram of the RRU implementing the lifting function provided in this embodiment, referring to fig. 3, in this embodiment, for RRU, (1) a soft logic lifting module log2ddr_inf is added to a DDR interface interaction module ddr_ inferconnect _inf, and this module may be connected to any target functional module to be analyzed according to needs, and the required preset type data is extracted from the target functional module. (2) The frequency domain CPRI module is added with a frequency domain lifting function, can also extract frequency domain data reaching 80ms, and supports uplink frequency domain lifting and downlink frequency domain lifting. (3) The time domain lifting function is added in the access processing module data_path_inf, so that time domain data up to 80ms can be extracted, and uplink time domain lifting and downlink time domain lifting are supported.
It should be noted that, the first prime enable command is generally a function module that may fail after the transmission link fails, and then specifically determines a target function module that needs to perform fault detection, extracts a preset data type of data from the target function module, and then generates the first prime enable command according to the preset data type of data that needs to be extracted from the target function module. The preset type data comprises business data, control data or other types of data.
The second data source and the third data source are usually one of preset data sources, for example, the entry data or the exit data of the CPRI protocol side of the second data source. The third data source is data input to or output from the pass-through module.
The second and third upgrade orders are usually upgrade orders generated when the link is detected to be faulty, and analysis of the entire link is required. For example, if the BBU side detects that the communication data is abnormal, the second and third upgrade enabling commands are triggered to be generated, and the frequency domain data and the time domain data are extracted to perform fault analysis on the transmission link.
The extraction of the preset type data, the frequency domain data and/or the time domain data in the steps 201-203 may be directly sent to the software for analyzing the extraction data, so as to realize data analysis, or the extraction data may be stored in a preset storage unit, and then the extraction data to be analyzed is analyzed by the software for analyzing the extraction data in the preset storage unit.
The embodiment provides a data extraction method for positioning faults of a transmission link, which extracts preset type data according to a determined first data source after receiving a first lifting enabling command so as to realize fault analysis on a target function module generating the preset type data through the preset type data. And receiving a second lifting enabling command, extracting frequency domain data through a second data source, receiving a third lifting enabling command, and extracting time domain data through a third data source. After receiving the extraction enabling command of the extracted data, the method directly locates the corresponding data source to extract the related data, does not influence the normal operation of the equipment, can extract the data with larger data quantity, and is beneficial to comprehensively and systematically analyzing the transmission link faults. Meanwhile, the data extraction method is not limited to the installation position of the equipment by remote control.
Further, on the basis of the above embodiment, the method further includes:
Storing the extracted extraction data in a preset storage unit in a preset format, wherein the extraction data comprises at least one of the following data: the preset type data, the frequency domain data and the time domain data;
The preset format is a data format which can be identified by preset software, and the preset software is software for analyzing transmission link faults according to the extraction data acquired from the preset storage unit.
It should be noted that, the extracted target data, frequency domain data and/or time domain data finally need to be input into corresponding preset software for analyzing the data. Therefore, after extracting the extraction data, the RRU performs format conversion on the extraction data and then stores the extraction data, so that the stored extraction data can be directly read by preset software for processing the data later, the format conversion is not needed, and the extraction data processing efficiency is improved.
Further, on the basis of the above embodiments, the method further includes:
if a data reading command is received, acquiring data conforming to the data reading command from the lifting data stored in the preset storage unit as data to be analyzed;
And transmitting the data to be analyzed to the preset software through an online debugging software OSP and/or a base station maintenance unit SCMT.
The data reading command is used for indicating features of data to be read, for example, the data reading command is to read the data acquired in a certain time period, or read all the frequency domain data and the time domain data currently stored in the preset storage unit.
The OSP and/or the SCMT are used for reading data to be analyzed from a preset storage unit.
Because the number of RRU radio frequency units is large, the operation is complicated for the operation of background maintenance personnel, and a software high-level is required to integrate the commands in base station maintenance software to simplify the operation.
The embodiment reads the data stored in the data storage unit through the OSP and/or the SCMT, and analyzes the data to be analyzed through preset software.
Further, on the basis of the above embodiments, the storing the extracted extraction data in a preset format in a preset storage unit includes:
Writing the extracted extraction Data into a RAM (Random Access Memory ), and storing the extraction Data into a DDR (Double Data Rate) in the preset format through an AXI (Advanced eXtensible Interface, bus protocol);
Wherein the clock domain between the RAM and the DDR is converted by a first-in first-out memory FIFO.
The clock domain indicates a rate of writing data into or reading data from a module having a memory function, for example, 491.25MHz for a RAM and 300MHz for a ddr. Because of the difference between the clock domains of the RAM and the DDR, if data in the RAM is to be written into the DDR, the RAM and the DDR need to be converted in clock domains so that the data in the RAM can be written into the DDR.
In order to store the extraction data, the embodiment selects the DDR as a preset storage unit, when the extraction data is written into the DDR, the extraction data is written into the RAM, and then the extraction data is stored into the DDR in a preset format (namely, a format matched with the AXI protocol) from the RAM through the AXI protocol. Because of the difference of clock domains between the RAM and the DDR, the RAM and the DDR cannot directly realize the writing of data, and the embodiment realizes the conversion of the clock domains in the RAM and the DDR through the FIFO, so that the data is successfully transferred from the RAM to the DDR.
In order to more clearly describe the writing of various kinds of extraction data from the RAM to the DDR, the following describes the extraction and storage processes of three kinds of data, respectively.

The uplink frequency domain extraction is to write the data of the entry of the optical port protocol processing module into the DDR, write the data of the exit of the downlink optical port protocol processing module into the DDR, and upload the data to the PC end in the form of file through an on-line debugging software (OSP) or a base station maintenance unit (SCMT).
Referring to fig. 5, for a frequency domain extraction module for extracting frequency domain data for a threshold value, a process of extracting and storing the frequency domain data includes:
