Description

File loading method and equipment and storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a file loading method, device, and storage medium.

Background

In a Base station system, physical connection between a BBU (Base Band Unit) and an AAU (Active Antenna Unit) is implemented by an optical port and an optical fiber, and the number of optical ports to be used and the optical port rate are determined by a specific communication scenario. Corresponding to different numbers and rates of optical ports, BBU and AAU need to load different FPGA (Field-Programmable Gate Array) version files. Each FPGA version file corresponds to one optical interface number and one optical interface speed.

In the existing scheme, only the FPGA version files corresponding to the current optical port number and the optical port rate are stored in the hard disks of the BBU and the AAU, and selection is not needed when the optical port file is used. However, since one FPGA version file only supports one optical port number and one optical port rate, when the number of optical ports or the optical port rate needs to be changed, the FPGA version files in the BBU and the AAU must be manually replaced by the network manager, which consumes a long time, and the probability of errors is increased by manually replacing the version files.

Therefore, a method for automatically loading version files is needed to reduce the time delay of replacing the version files and reduce the error probability.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and actions, those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order.

In the prior art, after being downloaded to a BBU from a management device such as a network management device, a version package of the BBU is stored in a hard disk. Since one BBU version package only includes one BBU FPGA version file, the BBU does not need to select the version file in the version file, and only needs to read the memory and load the memory for use, as shown in fig. 1. And after downloading the AAU version package from the network management equipment to the BBU, storing the AAU version package to the hard disk. Similarly, since one AAU version packet only includes one AAU FPGA version file, the BBU does not need to select the AAU FPGA version file in the AAU version packet, and directly transmits the AAU FPGA version file to the AAU through the optical fiber, and the AAU reads the AAU FPGA version file from the hard disk to the memory for loading and using, as specifically shown in fig. 2.

From the perspective of software management, both the BBU FPGA version file and the AAU FPGA version file only contain one FPGA version file, only the files need to be downloaded to a target hard disk, direct loading is not needed, and the process is simple. However, since one FPGA version file only supports one optical port number and one optical port rate, when the optical port number or the optical port rate to be used needs to be changed, the BBU FPGA version file and the AAU FPGA version file must be manually replaced by the network manager for upgrading, which is equivalent to re-running the flow shown in fig. 1 and 2, which consumes a long time, and the probability of error is increased when the version file is manually replaced.

In view of the above technical problems, the file loading method, device and storage medium provided in the embodiments of the present invention implement automatic acquisition and loading of version files during parameter modification by locally storing a plurality of BBU FPGA version files and a plurality of AAU FPGA version files and automatically acquiring and loading a target BBU FPGA version file and a target AAU FPGA version file based on configuration parameters, thereby reducing the time delay for replacing the version files and reducing the error probability.

Fig. 3 is a schematic flowchart of a file loading method according to an embodiment of the present invention, and as shown in fig. 3, the method includes:

s301, acquiring configuration parameters by a network manager;

specifically, the configuration parameters are parameters related to factors such as connection between the BBU and the AAU. The BBU can provide information input for the subsequent steps of acquiring the target BBU FPGA configuration file and the like by acquiring the configuration parameters through the network manager.

It can be understood that the obtaining of the configuration parameter may be event-triggered, for example, the network management side actively sends the configuration parameter to the BBU after modifying the parameter. The acquisition of the configuration parameters may also be triggered periodically, for example, the BBU acquires the configuration parameters to the network manager once every preset time. The acquisition time of the configuration parameter may be set according to a load condition of the network, and the like, which is not specifically limited in the embodiment of the present invention.

S302, acquiring a corresponding target BBU FPGA version file from a plurality of BBU FPGA version files locally stored in a BBU based on the configuration parameters, and acquiring indication information for indicating an AAU to load files based on the target BBU FPGA version file;

specifically, the BBU acquires a plurality of BBU FPGA version files in advance and stores the BBU FPGA version files locally, and after the configuration parameters are acquired, a target BBU FPGA version file corresponding to the configuration parameters can be automatically selected from the plurality of BBU FPGA version files stored locally based on preset rules. Therefore, the condition that the BBU FPGA version file needs to be manually retransmitted when the parameters are changed can be avoided.

And after the target BBU FPGA version file is obtained, the BBU further needs to further obtain indication information which is matched with the BBU FPGA version file and used for indicating the AAU to load the file, so that the matched AAU also synchronously obtains the corresponding target AAU FPGA version file to load the file.

And S303, loading the target BBU FPGA version file, and sending the indication information to the AAU, so that the AAU acquires the target AAU FPGA version file based on the indication information and carries out file loading.

Specifically, after the BBU acquires the target BBU FPGA version file, the step of loading the target BBU FPGA version file can be implemented. Wherein the loading step may be triggered based on a received control instruction, such as a reset instruction. For example, the BBU may wait for a reset instruction after acquiring the target BBU FPGA version file, and load the target BBU FPGA version file after receiving the reset instruction. In addition, the BBU can also acquire and load the configuration parameters and the target BBU FPGA version file after receiving the reset instruction, or acquire the configuration parameters first and acquire and load the target BBU FPGA version file after receiving the reset instruction. The embodiment of the present invention does not specifically limit the implementation sequence of the above steps. In addition, the loading step can also be directly carried out after the target BBU FPGA version file is obtained, and no additional trigger event is needed.

And the BBU loads the target BBU FPGA version file and simultaneously sends the indication information obtained in the step S302 to the AAU, so that the AAU can obtain and load the target AAU FPGA version file based on the indication information, thereby ensuring that the BBU is matched with the version file loaded by the AAU.

The file loading method provided by the embodiment of the invention automatically acquires and loads the target BBU FPGA version file from the plurality of BBU FPGA version files stored locally based on the configuration parameters, and simultaneously indicates the target BBU FPGA version file which needs to be loaded by the AAU to the AAU, thereby realizing the automatic acquisition and loading of the version file during parameter modification, reducing the time delay of version file replacement and reducing the error probability caused by manual replacement.

On the basis of the above embodiment of the present invention, for the indication information for indicating the AAU to perform file loading based on the target BBU FPGA version file, the embodiment of the present invention provides the following two implementation manners:

in the first embodiment, a corresponding target AAU FPGA version file is obtained from a plurality of AAU FPGA version files locally stored in a BBU based on the target BBU FPGA version file, and the indication information includes the target AAU FPGA version file;

correspondingly, the obtaining of the target AAU FPGA version file and the file loading by the AAU based on the indication information specifically includes: the AAU acquires the target AAU FPGA version file from the indication information and carries out file loading;

specifically, the multiple AAU FPGA version files may be stored in the BBU, and after the target BBU FPGA version file is selected by the locally stored multiple BBU FPGA version files, the BBU correspondingly selects the target AAU FPGA version file from the locally stored multiple AAU FPGA version files, and adds the selected target AAU FPGA version file to the indication information. Therefore, after receiving the indication information, the AAU can acquire the target AAU FPGA version file from the indication information and load the file.

In a second embodiment, a file identifier corresponding to the target AAU FPGA version file is determined based on the target BBU FPGA version file, and the indication information includes the file identifier;

correspondingly, the obtaining, by the AAU, a target AAU FPGA version file based on the indication information and performing file loading specifically include: and the AAU acquires the target AAU FPGA version file from a plurality of AAU FPGA version files locally stored in the AAU and loads the target AAU FPGA version file based on the file identifier.

Specifically, the multiple AAU FPGA version files may also be stored in the AAU, and after the target BBU FPGA version file is selected from the multiple BBU FPGA version files stored locally by the BBU, the target AAU FPGA version file is correspondingly selected from the multiple AAU FPGA version files stored locally by the AAU, and the file identifier of the selected target AAU FPGA version file is added to the indication information. Therefore, after receiving the indication information, the AAU can obtain a target AAU FPGA version file from a plurality of locally stored AAU FPGA version files according to the file identifier of the target AAU FPGA version file in the indication information, and further complete file loading.

The file loading method provided by the embodiment of the invention can store the AAU FPGA version files in the BBU and can also store the AAU FPGA version files in the AAU, thereby providing a more flexible file storage selection mode. When the AAU storage space is insufficient, the AAU FPGA version files can be used, and the file loading method of the embodiment of the invention is ensured to be smoothly implemented. When the storage space of the AAU is enough, the AAU FPGA version files can be directly stored in the AAU, so that the indication information only needs to indicate the file identification, and the time delay of the whole loading process can be further reduced for the file loading method provided by the embodiment of the invention.

On the basis of the foregoing embodiment of the present invention, the configuration parameter may include a card optical interface rate, where the card optical interface rate is used to indicate a speed specification of an adopted optical interface, such as 100G, 25G, and the like.

When the optical port rate of the board card is 100G, the target BBU FPGA version file is a 100G single-fiber BBU FPGA version file, and the target AAU FPGA version file is a 100G single-fiber AAU FPGA version file

Further, the configuration parameters may further include an optical port compression mode. The optical interface compression mode is used for indicating whether the optical interface adopts a compression mode or a non-compression mode.

The optical port compression mode is used for indicating whether the number of carrier aggregation CA bits occupied by a logic channel between the AAU and the BBU is compressed or not, and the number of the carrier aggregation CA bits is a configuration channel for the fpga. And when the optical port compression mode is compression, the number of CA bits required to be occupied by each logic channel is reduced by half.

The optical port rate of the board card is 25G, when the optical port compression mode is uncompressed, the target BBU FPGA version file is a 25G four-fiber BBU FPGA version file, and the target AAU FPGA version file is a 25G four-fiber AAU FPGA version file.

Alternatively, the configuration parameters may further include an optical port compression mode and an antenna mode. The antenna mode is used to indicate whether a smart antenna mode or a non-smart antenna mode is employed.

When the antenna mode is the intelligent antenna mode, the number of the intelligent antennas is larger than or equal to the preset number, and periodic antenna calibration operation can be carried out. And when the antenna mode is a non-intelligent antenna mode, the number of the intelligent antennas is smaller than a preset number, and the antenna calibration operation is not performed. Wherein the preset number may be 8, for example.

The optical port rate of the board card is 25G, the optical port compression mode is compression, when the antenna mode is a non-intelligent antenna mode, the target BBU FPGA version file is a 25G single-fiber chamber sub-BBU FPGA version file, and the target AAU FPGA version file is a 25G single-fiber AAU FPGA version file.

Or, the configuration parameters further include an optical port compression mode, an antenna mode, and the number of optical ports used by the radio frequency unit. The number of light ports is used to indicate the number of light ports used, e.g. 1, 2 or 4, etc.

when the optical port rate of the board card is 25G, the optical port compression mode is compression, the antenna mode is an intelligent antenna mode, and the number of used optical ports of the radio frequency unit is 1, the target BBU FPGA version file is a 25G single-fiber macro-station BBU FPGA version file, and the target AAU FPGA version file is a 25G single-fiber AAU FPGA version file;

when the optical port rate of the board card is 25G, the optical port compression mode is compression, the antenna mode is an intelligent antenna mode, and the number of the used optical ports of the radio frequency unit is 2, the target BBU FPGA version file is a 25G dual-optical fiber BBU FPGA version file, and the target AAU FPGA version file is a 25G dual-optical fiber AAU FPGA version file.

On the basis of the above embodiment of the present invention, the acquiring a corresponding target BBU FPGA version file from a plurality of BBU FPGA version files locally stored in a BBU based on the configuration parameter, and acquiring indication information for indicating an AAU to perform file loading based on the target BBU FPGA version file further includes:

Specifically, due to the limitation of factors such as the current storage technology, the storage space of the BBU and the AAU is relatively limited, and the AAU FPGA version file is relatively large, so that in order to save the storage space, only a small number of the most frequently used AAU FPGA version files can be stored in the AAU or the BBU. For example, the locally stored BBU FPGA version file may include a 25G single fiber macro station version, a 25G single fiber room division version, a 25G dual fiber version, a 25G quad fiber version, and a 100G single fiber version, but to save memory space, the AAU FPGA version file only stores the most commonly used 25G single fiber version and 25G dual fiber version.

But this may result in the target AAU FPGA version file selected based on the configuration parameters not being present in the BBU or AAU. Therefore, under the condition that the required target AAU FPGA version file does not exist locally, the BBU needs to send prompt information to a network manager or other management parties to acquire the target AAU FPGA version file or modify the configuration parameters, so that the AAU FPGA version file is loaded smoothly, and the base station operates normally.

On the basis of the above embodiment of the present invention, the file loading method further includes: and when the configuration parameter is failed to be acquired, adopting a preset default configuration parameter as the configuration parameter.

Specifically, due to network interruption or other accidents and emergencies, the BBU may not obtain the configuration parameters, and in this case, in order to ensure smooth execution of the loading process, in the embodiment of the present invention, default configuration parameters are set in advance in the BBU, for example, the card optical port rate is set to be 25G by default, the optical port compression mode is compression, the antenna mode is a non-smart antenna mode, and the number of optical ports used by the radio frequency unit is 1. Therefore, when the BBU fails to acquire the configuration parameters, the preset default configuration parameters can be used as the configuration parameters to select the target BBU FPGA file and the target AAU FPGA file.

Optionally, when the configuration parameter is failed to be obtained, the configuration parameter used last time may also be used as the configuration parameter used this time.

On the basis of the above embodiment of the present invention, the file loading method further includes:

Specifically, the plurality of BBU FPGA version files are acquired from the BBU version packet, and compared with the prior art that one BBU version packet only comprises one BBU FPGA version file, the embodiment of the invention adds the plurality of BBU FPGA version files in one BBU version packet, so that the BBU can acquire the plurality of BBU FPGA version files at one time, and the acquisition efficiency is improved.

Correspondingly, the AAU version file package may also include a plurality of AAU FPGA version files, so that the AAU can obtain the plurality of AAU FPGA version files at one time.

Fig. 4 is a schematic flowchart of a file loading method according to another embodiment of the present invention, and as shown in fig. 4, the method includes:

specifically, the configuration parameters are parameters related to factors such as connection between the BBU and the AAU. After the BBU acquires the configuration parameters, the target BBU FPGA version file corresponding to the configuration parameters can be automatically acquired from a plurality of locally stored BBU FPGA version files based on preset rules. Therefore, the BBU FPGA version file can be prevented from being manually retransmitted when the parameters are changed.

And after the target BBU FPGA version file is obtained, the BBU further obtains indication information which is matched with the BBU FPGA version file and used for indicating the AAU to load the file, and the indication information is sent to the target AAU file. Accordingly, the AAU receives the indication information.

S402, acquiring a target AAU FPGA version file based on the indication information and loading the file.

Specifically, after receiving the indication information, the AAU obtains a corresponding target AAU FPGA version file based on the indication information, and loads the target AAU FPGA version file. Wherein the loading step can be performed, for example, upon re-accessing the BBU.

The file loading method provided by the embodiment of the invention automatically acquires the target AAU FPGA version file based on the indication information acquired by the BBU through the configuration parameters, realizes the automatic acquisition and loading of the version file during parameter modification, reduces the time delay of version file replacement, and reduces the error probability.

On the basis of the above embodiments of the present invention, for the indication information, the embodiments of the present invention provide two specific implementation manners:

in a first embodiment, the indication information includes the target AAU FPGA version file, where the target AAU FPGA version file is obtained by the BBU based on the target BBU FPGA version file from multiple AAU FPGA version files locally stored in the BBU;

In a second implementation manner, the indication information includes a file identifier, where the file identifier is a file identifier corresponding to the target AAU FPGA version file determined by the BBU based on the target BBU FPGA version file;

The file loading method provided by the embodiment of the invention can store the AAU FPGA version files in the BBU, and can also store the AAU FPGA version files in the AAU, thereby providing a more flexible file storage selection mode. When the AAU storage space is insufficient, the AAU FPGA version files can be used, and the file loading method of the embodiment of the invention is ensured to be smoothly implemented. When the storage space of the AAU is enough, the AAU FPGA version files can be directly stored in the AAU, so that the indication information only needs to indicate the file identification, and the time delay of the whole loading process can be further reduced for the file loading method provided by the embodiment of the invention.

On the basis of the above embodiment of the present invention, when the AAU locally stores a plurality of AAU FPGA version files, the file loading method further includes:

receiving an AAU version package, the AAU version package comprising the plurality of AAU FPGA version files.

Specifically, the multiple AAU FPGA version files are acquired from the AAU version package, and compared with the prior art in which one AAU version package only comprises one AAU FPGA version file, the AAU FPGA version files are added into one AAU version package in the embodiment of the invention, so that the AAU can acquire the multiple AAU FPGA version files at one time, and the acquisition efficiency is improved.

Fig. 5 is a schematic flowchart of a file loading method according to another embodiment of the present invention. As shown in fig. 5, a BBU version package integrates 5 BBU FPGA version files, and after being downloaded to a BBU through a network cable, the BBU FPGA version files are stored in a BBU hard disk, a software management module obtains one BBU FPGA version file according to configuration of a network manager, and the BBU reads the BBU FPGA version file from the hard disk into a memory for loading and use. Because the 5 BBU FPGA version files are stored in the BBU hard disk, and the FPGA version file at the BBU side is a dynamic loading mechanism, the FPGA version file can be obtained and loaded again each time the baseband board is reset, when the used BBU FPGA version file needs to be switched due to changes of the number of the used optical interfaces or the rate of the used optical interfaces, the network manager only needs to modify the parameters into corresponding values and then sends a reset instruction to the BBU through the operation maintenance tool, the flow of the software management module for obtaining and loading the target FPGA version file can be triggered, and further the switching is realized.

Fig. 6 is a flowchart illustrating a file loading method according to still another embodiment of the present invention. As shown in fig. 6, an AAU version package integrates 2 AAU FPGA version files, and after being downloaded to a BBU through a network cable, the files are stored in a BBU hard disk, and a software management module obtains an AAU FPGA version file according to configuration of a network manager, and the obtained AAU FPGA version file is downloaded to an AAU through an optical fiber and loaded and used by the AAU. Because 2 AAU FPGA version files are stored in the BBU hard disk, and the AAU accesses the baseband board again each time, whether the currently running AAU FPGA version is consistent with the target AAU FPGA version is compared, if not, the files are reloaded, when the number of the used optical ports or the speed of the optical ports changes and the used AAU FPGA version files need to be switched, the network manager only needs to modify the parameters into corresponding values, and sends a reset command and the like to the BBU or the AAU through an operation maintenance tool to trigger the AAU to access the BBU again, so that the procedures of comparing and loading the AAU FPGA version can be triggered, and further, the switching is realized. In addition, because only the target version file is downloaded to the AAU, the occupation condition of the storage resource on the AAU side is the same as that of the traditional scheme, and no additional increase is caused.

Fig. 7 is a flowchart illustrating a file loading method according to still another embodiment of the present invention. As shown in fig. 7, there are 4 parameters configurable by the network manager, which are: the method comprises the steps of board card optical port rate (value range: 25G/100G), local cell optical port compression mode (value range: no compression/compression), local cell antenna mode (value range: intelligent antenna mode/non-intelligent antenna mode) and radio frequency unit used optical port number (value range: 1/2/4). And the software management module selects the BBU FPGA version file according to the parameters configured by the network management module, and then selects the corresponding AAU FPGA version file according to the BBU FPGA version file. The parameter configuration is different, and the selected version files are different, for example:

(1) configuring the optical interface rate of a board card to be 100G, loading a 100G single optical fiber version on BBU, reporting to a management station because a 100G single optical fiber version file is not integrated in an AAU version packet, and informing a network manager to manually replace the AAU version packet or modify parameters;

(2) configuring a board card optical port rate to be 25G, a local cell optical port compression mode to be non-compression, loading a 25G four-fiber version by BBU (base band unit), reporting to a management station because a 25G four-fiber version file is not integrated in an AAU version packet, and informing a network manager to manually replace the AAU version packet or modify parameters;

(3) configuring a board card optical port rate to be 25G, a local cell optical port compression mode to be compression, a local cell antenna mode to be a non-intelligent antenna mode, loading 25G single fiber chamber sub-versions by BBU, loading 25G single fiber versions by AAU, and corresponding to the FPGA versions loaded by BBU and AAU;

(4) the optical port rate of the configuration board card is 25G, the optical port compression mode of the local cell is compression, the antenna mode of the local cell is an intelligent antenna mode, when the radio frequency unit is unsuccessfully inquired by using the optical port number, a 25G single optical fiber chamber division version is loaded by BBU, a 25G single optical fiber version is loaded by AAU, and FPGA versions loaded by BBU and AAU are corresponding.

(5) Configuring a board card optical port rate to be 25G, a local cell optical port compression mode to be compression, a local cell antenna mode to be an intelligent antenna mode, 1 optical port used by a radio frequency unit, loading a 25G single-fiber macro station version by a BBU (baseband unit), loading a 25G single-fiber version by an AAU (architecture automation unit), and corresponding BBU and AAU loaded FPGA (field programmable gate array) versions;

(6) the optical port rate of the configuration board card is 25G, the optical port compression mode of the local cell is compression, the antenna mode of the local cell is an intelligent antenna mode, the number of used optical ports of the radio frequency unit is 2, a BBU loads a 25G dual-optical-fiber version, an AAU loads a 25G dual-optical-fiber version, and BBU and AAU loaded FPGA versions are corresponding.

According to the (3) - (6), the FPGAs loaded at the BBU and AAU sides are always the single fiber version or the dual fiber version at the same time, so the file loading method provided by the embodiment of the invention can avoid the problems of AAU access abnormality, cell establishment abnormality and service abnormality caused by the inconsistency of the FPGAs at the BBU and AAU sides.

Meanwhile, when the optical port compression mode and the local cell antenna mode are unsuccessfully inquired, in order to ensure the loading of the version file, the optical port compression mode is automatically configured to be compression, the local cell antenna mode is a non-intelligent antenna mode, and the user is informed of the automatically configured value and the corresponding FPGA version.

In addition, when the number of used optical ports or the optical port rate and the like are changed, both the BBU and the AAU need to switch the used FPGA version files, and the network manager can realize the switching only by modifying the parameters into corresponding values and then issuing a reset instruction to the BBU through an operation and maintenance tool.

For example, in the current physical environment, the AAU is a macro station AAU, the AAU is connected to the baseband board through 2 25G optical ports, and accordingly, the BBU and the AAU both use 25G dual-fiber versions, the parameter board card optical port rate is 25G, the local cell optical port compression mode is compression, the local cell antenna mode is smart antenna mode, and the number of optical ports used by the radio frequency unit is 2. When the used optical port needs to be changed into 1 25G optical port, at the moment, the network manager only needs to change the number of the optical ports used by the radio frequency unit to 1 and then issues a BBU reset command through the operation and maintenance tool. And for the BBU, after the BBU is reset, the software management module acquires and loads the BBU FPGA version file again. For the AAU, after the BBU is reset, the AAU can be accessed again, and then the comparison and loading processes of the AAU FPGA version files are triggered. Therefore, after the BBU is reset, and the state of the BBU is recovered to be normal and the AAU is accessed again, the BBU FPGA and the AAU FPGA can be successfully switched to the target version.
