Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The application discloses a communication processing method and electronic equipment, which solve the problem that character equipment is disordered in use due to the fact that the same character equipment is used simultaneously in multiple parties in the prior art by providing a virtual equipment driving layer which can run between an application layer and a physical equipment driving layer, respectively realizing independent character equipment for different communication applications in the virtual equipment driving layer and taking charge of data stripping work of dual-mode communication applications in the virtual equipment driving layer, and solve the problem that the strong coupling is caused among different communication applications due to data stripping in the application layer in the prior art.
Referring to fig. 1, a flow chart of a communication processing method in an embodiment of the present application is provided, which specifically includes:
in step 101, in uplink communication of dual-mode communication application, a data processing module included in a virtual device driver layer acquires first dual-mode mixed data in a physical device driver layer, and separates first communication data and second communication data in the first dual-mode mixed data.
Dual mode communication means that the device system is simultaneously operating in two communication networks, i.e. the system can transmit and receive data based on two different communication networks, e.g. for a 5G/4G dual mode, the system can simultaneously transmit/receive 5G and 4G data.
Fig. 2 shows a communication framework to which the communication processing method of the present application is applied, including an application layer, a driver layer, and an underlying hardware layer. Wherein the application layer includes at least a first communication application and a second communication application to support a dual mode communication application in the system, and the first communication application and the second communication application may be a 5G application and a 4G application, respectively; in the traditional technology, the driving layer is a physical device driving layer and is responsible for providing character devices for an upper layer application to realize data access to bottom layer hardware;
the underlying hardware may be, but is not limited to, an XDMA-based PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) device or a PCI (Peripheral Component Interconnect, peripheral component interconnect standard) device, such as an FPGA (Field Programmable Gate Array ) device, etc., but may also be a QDMA-based PCIE device or a PCI device. Where XDMA is the ip core of Xilinx, QDMA refers to queue DMA (Direct Memory Access ).
In the following, a PCIE device "FPGA device" based on XDMA is mainly taken as an example of bottom hardware, and a communication processing method and an electronic device of the present application will be described.
In this application, referring to fig. 2, at an upper layer of the physical device driver layer, there is further provided a virtual device driver layer operable between the application layer and the physical device driver layer, that is, the driver layer in this application includes, in addition to the physical device driver layer, a virtual device driver layer located at an upper layer thereof.
The virtual device driver layer includes two parts:
1) The virtual device comprises a first virtual device corresponding to a first communication application and a second virtual device corresponding to a second communication application, wherein the first virtual device is used for providing independent character devices for the first communication application, and the second virtual device is used for providing independent character devices for the second communication application.
2) The data processing module is responsible for carrying out dual-mode data stripping or assembling/combining processing in dual-mode communication application; the data processing module runs on the lower layer of the virtual device and can be regarded as a public processing module applied to the driving layer of the virtual device by dual-mode communication.
Dual mode communication applications include uplink and downlink communications.
Based on the communication architecture, in uplink communication of dual-mode communication application, physical equipment of a bottom hardware layer, such as an FPGA, transmits dual-mode mixed data to a data processing module of a virtual equipment driving layer through physical equipment driving, and the data processing module correspondingly acquires the dual-mode mixed data from the physical equipment driving layer and strips different communication data in the uplink dual-mode mixed data to separate first communication data and second communication data. The embodiment refers to uplink dual-mode mixed data as first dual-mode mixed data.
As shown in fig. 3, the data processing module may poll the first dual mode mixed data in the physical device driver layer via a read thread and buffer the first dual mode mixed data in a FIFO (First Input First Output, first in first out) queue for storing the upstream mixed data.
Communication data of different communication applications (e.g., 5G, 4G communication applications) have different frame header information, and data frames of communication data of different communication applications typically have different attributes, e.g., the data frame lengths of 5G data and 4G data are different.
Optionally, for the first dual-mode mixed data buffered in the FIFO queue, identifying, according to frame header information of the data, whether a data type of each data in the first dual-mode mixed data is a first communication data type or a second communication data type; alternatively, in an embodiment, the data type of each data in the first dual-mode mixed data may be identified as the first communication data type or the second communication data type according to the data frame attribute, such as the length of the data frame; or, the data type identification can be performed by combining the frame header information of the data and the data frame attribute.
For example, whether the data is 5G data or 4G data is identified based on frame header information and/or data frame attributes of the data.
The data processing module further separates the different types of data based on identifying the data type.
For 5G/4G dual-mode communication, based on the processing, the stripping of 5G data and 4G data in the 5G/4G dual-mode mixed data can be completed in the virtual device driving layer provided by the application.
After the data processing module finishes processing the uplink first dual-mode mixed data, separating the first communication data and the second communication data from the first communication data and the second communication data, respectively sending the separated different communication data to the character devices corresponding to different communication applications, namely sending the first communication data to the first virtual device in the virtual device driving layer, sending the second communication data to the second virtual device in the virtual device driving layer, and sending the different communication data to the upper-layer application to which the different communication applications belong by means of the character device functions provided by the first virtual device and the second virtual device in the respective communication applications.
Taking the example that the first communication application and the second communication application are a 5G application and a 4G application, respectively, the first communication data and the second communication data separated from the first dual-mode mixed data are respectively 5G data and 4G data, the first virtual device is correspondingly a 5G virtual device and is used for providing independent character devices for the 5G application of the upper layer, and the second virtual device is a 4G virtual device and is used for providing independent character devices for the 4G application of the upper layer.
Accordingly, for 5G/4G dual mode communication, the data processing module may send 5G data separated from the 5G/4G dual mode hybrid data to the 5G virtual device and send the separated 4G data to the 4G virtual device.
Based on the independent virtual devices (character devices), the communication applications of different types receive uplink communication data from the underlying physical devices such as the FPGA, the received data is communication data of a communication type corresponding to the communication application, and data stripping of dual-mode data is completed in a virtual device driving layer without executing data stripping and data forwarding work to other communication applications by means of a certain communication application in an application layer.
As can be seen from the above solutions, in the communication processing method provided in the embodiments of the present application, for dual-mode communication applications, a virtual device driver layer that can be run between an application layer and a physical device driver layer is provided, and a first virtual device for performing data access communication with a first communication application, a second virtual device for performing data access communication with a second communication application are built in the virtual device driver layer, and a data processing module for separating at least different types of communication data for dual-mode mixed data for uplink transmission is built. By means of the first virtual device and the second virtual device in the virtual device driving layer, independent character devices are respectively provided for the first communication application and the second communication application, the problem of disordered use when multiple parties of applications use the same character device simultaneously is avoided, data stripping work of the dual-mode communication application is completed in the virtual device driving layer instead of the application layer, and strong coupling requirements on upper-layer applications are avoided.
Dual mode communication applications include uplink and downlink communications.
Accordingly, for dual-mode communication applications (such as 5G/4G dual-mode communication), the communication processing method disclosed in the present application may further include a processing procedure of downlink communication, where the processing procedure of downlink communication is shown in fig. 4, and specifically includes:
in step 401, in downlink communication of the dual-mode communication application, the first virtual device receives first communication data sent by the first communication application.
The downlink communication process of the dual-mode communication application is inverse to the uplink communication process, and is used for sending dual-mode communication data provided by different communication applications (such as 5G and 4G) at the upper layer to physical equipment of the bottom hardware layer, such as FPGA.
Specifically, for a first communication application in dual-mode communication, after generating first communication data to be transmitted to an underlying hardware layer in a downlink manner, the generated first communication data is sent to a first virtual device in a virtual device driving layer (for example, a 5G application sends 5G data to a 5G virtual device in the virtual device driving layer), and data access interaction is performed with an underlying component by means of an independent character device function of the first virtual device.
And the second communication application correspondingly sends the generated second communication data to a second virtual device in the virtual device driving layer, for example, the 4G application sends the 4G data to the 4G virtual device in the virtual device driving layer.
The second virtual device and the first virtual device are independent of each other and do not interfere with each other.
And 403, the data processing module performs combination processing on the downlink first communication data and the downlink second communication data to obtain second dual-mode mixed data.
Referring to fig. 3 in combination, the data processing module combines different communication data transmitted from an upper layer into dual-mode mixed data, and caches the combined dual-mode mixed data in a FIFO queue for storing downstream mixed data. The present embodiment refers to the dual mode mixed data obtained by combining here as second dual mode mixed data.
And then, the data processing module writes the combined second double-mode mixed data into the physical equipment by utilizing a write thread, and transmits the second double-mode mixed data to the physical equipment of the bottom hardware layer, such as an FPGA, through the physical equipment drive so as to complete the downlink double-mode communication transmission.
According to the embodiment of the application, the virtual device driving layer which can run between the application layer and the physical device driving layer is provided, and the virtual device is respectively built for different communication applications in the virtual device driving layer to respectively provide independent character devices for different applications, so that in dual-mode communication applications, no matter in uplink communication or downlink communication, different upper-layer applications independently use the corresponding character devices in the virtual device driving layer to realize data access interaction with the bottom-layer physical device, the problem of confusion in use when multiple-party applications use the same character device at the same time is avoided, and the work such as data stripping or combination of dual-mode communication applications is also completed in the virtual device driving layer, so that the strong coupling requirements on different upper-layer applications are avoided.
In an embodiment, referring to a flow chart of the communication processing method provided in fig. 5, before executing the communication processing for the dual-mode communication application, the method further includes:
in practical application, a drive code of a virtual device drive layer is pre-written, and the drive code comprises: the function code of the data processing module is used for providing the related function code of the first virtual device of the independent character device for the first communication application (such as a 5G application) of the upper layer, providing the related function code of the second virtual device of the independent character device for the second communication application (such as a 4G application) of the upper layer, and providing the function code of the data processing module.
Before communication processing of the dual-mode communication application is executed, for example, when the system is started or the system enters the dual-mode communication application, driving codes of a virtual device driving layer are loaded and operated, creation of the first virtual device and the second virtual device is completed by operating related codes in the virtual device driving layer, and accordingly independent character devices are respectively provided for the first communication application and the second communication application at the upper layer at the virtual device driving layer through the created first virtual device and second virtual device.
Wherein the created first virtual device comprises: at least one first data channel for a first communication data transmission between a first communication application and a data processing module; the second virtual device includes: at least one second data channel for a second communication data transmission between a second communication application and the data processing module.
Illustratively, a first virtual device is created for a 5G application that includes the following 4 5G data channels:
xdma0_5g_ch0、xdma0_5g_ch1、xdma0_5g_ch2、dma0_5g_ch3。
creating a second virtual device for the 4G application comprising the following 4G data channels:
xdma0_4g_ch0、xdma0_4g_ch1、xdma0_4g_ch2、xdma0_4g_ch3。
and the upper layer application independently uses the corresponding virtual devices to complete data interaction with the lower layer physical devices, for example, the 5G application uses the xdma05g_chx, the 4G application uses the xdma04 g_chx, wherein chx represents any one or more of ch0-ch3, and the use of the same character device by different upper layer applications is avoided.
In an embodiment, the virtual device driver layer further includes at least one buffer.
The first virtual device and the first communication application perform data interaction through the corresponding cache region and the first data channel; and the second virtual equipment and the second communication application perform data interaction through the corresponding buffer area and the second data channel.
Optionally, referring to fig. 3, the at least one buffer area further includes:
1) A first upstream buffer and a first downstream buffer corresponding to at least one first data channel.
For the case where the first communication application and the second communication application are 5G and 4G applications, respectively, the first UpLink buffer is denoted as 5G UL (UpLink) and the first DownLink buffer is denoted as 5G DL (DownLink) in fig. 3.
2) A second upstream buffer area and a second downstream buffer area corresponding to at least one second data channel; the second upstream buffer is denoted as 4G UL and the second downstream buffer is denoted as 4G DL in fig. 3.
Correspondingly, in the uplink communication of the dual-mode communication application, after the data processing module strips the first communication data and the second communication data in the first dual-mode mixed data, the first communication data is further cached in the first uplink cache region, and the second communication data is cached in the second uplink cache region. And then, the first communication data cached in the first uplink cache area is sent to the first communication application through a corresponding first data channel in the first virtual device.
If the stripped uplink 5G data is buffered to 5G UL, the stripped uplink 4G data is buffered to 4G UL, the 5G data is sent to the 5G application by xdma0_5g_ch, and the 5G data is sent to the 4G application by xdma 0_4g_ch.
In downlink communication of dual-mode communication application, a corresponding first data channel of a first virtual device receives first communication data sent by the first communication application, and caches the received first communication data to a first downlink cache region, a corresponding second data channel of a second virtual device receives second communication data sent by a second communication application, and caches the received second communication data to a second downlink cache region, and then a data processing module respectively reads data from the first downlink cache region and the second downlink cache region to obtain the first communication data and the second communication data, and performs combination processing on the first communication data and the second communication data.
For example, 5G data sent by the 5G application is received and buffered to 5G DL through xdma05g_ch, 4G data sent by the 4G application is received and buffered to 4G DL through xdma04g_ch, and the data processing module reads the 5G data and the 4G data from the 5G DL and the 4G DL respectively and combines them to process them into second dual-mode mixed data.
In this embodiment, different buffer areas are created for uplink and downlink communications of different communication applications, so as to avoid data buffer confusion between different communication applications and between uplink and downlink communications of the same communication application, and accordingly avoid data read-write errors caused by data buffer confusion.
Additionally, in an embodiment, with reference to fig. 6 in combination, the communication processing method of the present application also provides a virtual driven bypass (bypass) mode for single mode communication applications.
When the method and the device are applied, the optional function of the bypass mode can be further provided, and a user is supported to configure whether the single-mode communication application adopts the bypass mode or not according to actual conditions.
If the single-mode communication application is configured to not adopt the bypass mode, the upper-layer communication application can utilize the corresponding virtual equipment in the virtual equipment driving layer to be in butt joint with the physical equipment driving layer; if the single-mode communication application is configured to adopt the bypass mode, when the first communication application and the second communication application are used independently, the first communication application or the second communication application can bypass the virtual device driving layer based on the bypass mode and directly interface with the physical device driving layer, namely, the application layer directly performs data interaction with the physical device through the physical device driving to reduce the consumption of resources.
Corresponding to the above-mentioned communication processing method, the embodiment of the application also discloses an electronic device, which may be, but is not limited to, a terminal device or a server supporting a dual-mode communication application.
The electronic device includes, as shown in fig. 7, a constituent structure including:

a physical device 20 and a physical device driver 30;

By way of example, the first communication application and the second communication application may be a 5G application and a 4G application, respectively, and the physical device may be, but is not limited to, an FPGA.
The virtual device driver and the physical device driver form a driving layer between an upper layer communication application (a first communication application and a second communication application) and the physical device, and the virtual device driver operates on an upper layer of the physical device driver, and when the virtual device driver operates, the virtual device driver can be used for executing the communication processing method disclosed in any embodiment above.
The functions of each component of the electronic device and the communication processing procedure implemented by the cooperative work of each component can be specifically referred to the description of the communication processing method of the present application in each embodiment, which is not repeated herein.
