In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

With the development of communication technology, data services put forward higher requirements on data transmission time.

For example, in artificial intelligence (AI) applications, multi-level AI processing is usually used to improve data analysis efficiency and user experience. Among them, multi-level AI processing can be understood as the division of labor between terminal equipment and network measurement network elements for data processing. Specifically, referring to the schematic diagram of a multi-level AI processing application scenario shown in Figure 2, to realize the image recognition function, the terminal device can perform partial operations on the captured image to obtain intermediate state data; further, the terminal device can convert the intermediate state The data is sent to the application server through the communication network for further calculation, and finally the application server recognizes the captured image as "a cat", and returns the recognition result to the terminal device through the communication network.

It should be understood that in the above-mentioned AI reasoning scenario, it is necessary to continuously pay attention to the total time of data round-trip. As shown in FIG. 3, the total time of data round trip may include: the processing time of the terminal device, the uplink transmission time of the intermediate state data from the terminal device to the application server, the data processing time of the application server, and the transmission of the recognition result from the application server to the application server. The downlink transmission time of the terminal device. That is to say, in the AI reasoning scenario, if the recognition result of the captured image is required to be obtained within 1 second, it means that the total time for the terminal device from capturing the image to obtaining the recognition result from the application server is 1 second.

In practical applications, the QoS model in 5G technology can be used to ensure data transmission requirements. Referring to the QoS model shown in Figure 4, the terminal device and UPF can map application layer data to multiple QoS flows for transmission, and each QoS flow corresponds to different QoS parameters.

Here, as an important measure of communication quality, QoS parameters are usually used to indicate the characteristics of QoS flows. QoS parameters can include but are not limited to: 5G QoS identification (5G QoS Index, 5QI), allocation and retention priority (Allocation And Retention Priority , ARP), guaranteed bit rate (Guaranteed Flow Bit Rate, GFBR), maximum flow bit rate (Maximum Flow Bit Rate, MFBR), maximum packet loss rate (Maximum Packet Loss Rate), packet delay budget (Packet Delay Budget, PDB) , access network packet delay budget (AN-PDB), packet error rate (Packet Error Rate, PER), scheduling priority, average time window (Averaging Window), resource type (Resource Type), maximum data burst (Maximum Data Burst Volume), UE aggregated maximum bit rate (UE-AMBR), session aggregated maximum bit rate (Session-AMBR), etc.

In the embodiment of the present application, the UPF and the terminal device may predetermine a filter (ie, a Filter, or a service data flow template), and the filter may be a trapezoid on the left and a parallelogram on the right in FIG. 4 . Wherein, the filter may include parameters describing the characteristics of the data packet. Specifically, the UPF and the terminal device can use filters to filter out uplink or downlink data packets that meet the characteristics of the data packets, and bind them to a certain QoS flow for transmission.

Usually, terminal devices or application servers directly set the required uplink/downlink transmission rate, uplink/downlink packet loss rate and other parameters, so that network elements on the network side can build QoS flows based on the required parameters. However, in fact, the available resources on the network side are not static, and in some cases cannot meet the requirements of the terminal equipment, which leads to the problem of transmission failure.

Based on this, an embodiment of the present application provides an information processing method. Specifically, the first network element can receive a request message; the request message includes the requirement information of the file to be transmitted; the request message is used to request information transmission of the file to be transmitted; the file to be transmitted includes one or more data packets; wherein the demand information includes at least one of the file size information, time requirement information, and feature information of the file to be transmitted The first network element determines a filter and/or a QoS parameter for the file to be transmitted based on at least one item of the file size information, the time requirement information, and the feature information. That is to say, the first network element can independently determine the filter and/or QoS parameters required for transmitting the file to be transmitted based on the file size, time requirement, and characteristic information of the file to be transmitted, so as to improve the flexibility of QoS-related parameter setting degree, so as to ensure the correct transmission of data.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples.

For example, the file size information of the file to be transmitted may include a parameter: 50 megabytes, that is, the file size of the first subfile and the file size of the second subfile are both 50 megabytes.

In the embodiment of the present application, the time requirement information is used to indicate the maximum time (or called the time limit) for completing the transmission of the file to be transmitted, which can also be understood as the delay requirement for transmitting the file to be transmitted.

Here, the second network element may be a UPF or a next-generation processing network element, which is not limited in this embodiment of the present application.

It should be understood that the time requirement information may be represented by a time point, which represents the last moment when the transmission of the file to be transmitted is completed.

The length of time can be the length of time it takes from the start of the transmission of the file to be transmitted to the completion of the transmission. The length of time from one data packet to the completion of the last data packet transmission.

Feature information can be information specific to the file to be transmitted, information that can be distinguished from other files, for example, feature information can be IP address/port number, or type of service (Type of Service) information carried on the IP header, or It may be the data type and/or content type of the file to be transferred, which is not limited in this embodiment of the present application.

Step 520, the first network element determines a filter and/or QoS parameter for the file to be transmitted based on at least one item of file size information, time requirement information, and feature information.

It can be understood that the first network element may formulate policy and charging control (Policy and Charging Control, PCC) rules based on at least one of the file size information, time requirement information, and feature information carried in the request message. Wherein, the PCC rule may include filters and/or QoS parameters for the files to be transmitted.

In this embodiment of the present application, a filter may also be called an SDF template, which is used to describe characteristics of a data packet corresponding to a file to be transmitted. It can be understood that, during the service data transmission process, the data packet corresponding to the file to be transmitted can be identified from the user plane data packets based on the filter.

Optionally, the filter may be determined based on feature information in the request message. That is to say, after receiving the request message, the first network element may determine the filter corresponding to the file to be transmitted based on the characteristic information of the file to be transmitted carried in the request message. In this way, during the service data transmission process, the data sender can identify the data packet corresponding to the above-mentioned file to be transmitted from the user plane data packets based on the filter.

Optionally, the QoS parameters may include at least one of the following:

QoS identification information;

The transmission rate of uplink transmission;

The transmission rate of the downlink transmission;

Transmission delay of uplink transmission;

Transmission delay of downlink transmission;

Packet loss rate of uplink transmission;

The packet loss rate of downlink transmission;

Packet error rate of uplink transmission;

Packet error rate of downlink transmission;

ARP;

Resource Type;

Scheduling priority;

Average time window.

Wherein, the QoS identification information may be 5QI or next-generation QoS identification information, which is not limited in this embodiment of the present application.

In this embodiment of the application, the first network element can distinguish uplink transmission from downlink transmission, and determine parameters corresponding to UL and DL, such as transmission rate of uplink transmission, transmission rate of downlink transmission, transmission delay of uplink transmission, downlink transmission Transmission delay, packet loss rate of uplink transmission, packet loss rate of downlink transmission, packet error rate of uplink transmission, packet error rate of downlink transmission, etc.

Wherein, the transmission rate of uplink transmission may include at least one of uplink GFBR, uplink MFBR, uplink UE-AMBR, and uplink Session-AMBR. Correspondingly, the transmission rate of downlink transmission may include at least one of downlink GFBR, downlink MFBR, downlink UE-AMBR, and downlink Session-AMBR, which is not limited in this embodiment of the present application.

In addition, the transmission delay of uplink transmission may include parameters such as uplink PDB and/or uplink AN-PDB, and correspondingly, the transmission delay of downlink transmission may include parameters such as downlink PDB and/or downlink AN-PDB. This is not limited.

It can be understood that if the file to be transmitted only includes the first sub-file for uplink transmission, the QoS parameters may include related transmission parameters for uplink transmission, such as the transmission rate of uplink transmission, the transmission delay of uplink transmission, the uplink The packet loss rate of transmission, or the packet error rate of uplink transmission, etc. If the file to be transmitted only includes the second sub-file for downlink transmission, the QoS parameters may include related transmission parameters for downlink transmission, such as the transmission rate of downlink transmission, the transmission delay of downlink transmission, and the transmission packet loss of downlink transmission rate, or the packet error rate of downlink transmission, etc. In addition, if the file to be transmitted includes the first sub-file and the second sub-file, the QoS parameters may include parameters for uplink transmission and downlink transmission, such as the transmission rate of uplink transmission and downlink transmission, the transmission time of uplink transmission and downlink transmission. Delay, packet loss rate of uplink transmission and downlink transmission, or packet error rate of uplink transmission and downlink transmission, etc.

Optionally, QoS parameters may be determined based on file size information and/or time requirement information. That is to say, the first network element may determine relevant transmission parameters for uplink transmission and downlink transmission based on the file size information and/or time requirement information carried in the request information.

For example, the size of the first sub-file is 100 megabytes, and the first time request information is 5 seconds, then the first network element may determine that the transmission rate of the uplink transmission is 20 megabytes per second (mbps).

In the embodiment of the present application, for the case where the file to be transmitted includes the first sub-file and the second sub-file, the first network element can follow the general requirements of the third party (such as terminal equipment or application server) for uplink transmission and downlink transmission , and combined with the actual wireless resource scheduling situation, respectively determine the relevant transmission parameters of the uplink transmission and the downlink transmission, so that the determined relevant transmission parameters of the uplink transmission and the downlink transmission can meet the requirements of the third party.

For example, the size of the first sub-file is 100 megabytes, the size of the second sub-file is 5 megabytes, and the required round-trip time is 5 seconds. If there are few uplink resources currently available, but more downlink resources are available, the first network element can set the transmission rate of uplink transmission to 25 mbps, that is, 100 Mbps/4 seconds; configure the transmission rate of downlink transmission to 5 mbps, also That is 5 trillion/1 second. If the current available uplink resources are more, but the available downlink resources are less, the first network element can set the transmission rate of uplink transmission to 50mbps, that is, 100M/2 seconds; the transmission rate of downlink transmission is configured as 1.67mbps, That is 5 trillion/3 seconds. It should be understood that the uplink transmission rate and the downlink transmission rate may also be other values, as long as the file size information and time requirement information are met.

That is to say, in the information processing method provided by the embodiment of the present application, the first network element can autonomously determine the filter and/or QoS parameters required for transmission based on the file size, time requirement, and feature information of the file to be transmitted , improve the flexibility of QoS parameter setting, so as to ensure the correct transmission of data.

It should be noted that the request message may carry requirement information of one or more files to be transmitted, and the embodiment of the present application does not limit the quantity of requirement information carried in the request message. It can be understood that when the request message carries the requirement information of multiple files to be transmitted, the first network element can determine the filters and/or QoS parameters corresponding to the multiple files to be transmitted according to the request message, and different files to be transmitted correspond to The filters and/or QoS parameters can be different.

It should also be noted that the file to be transmitted may be a file for transmission at a specific time point/period. That is to say, when the file is transmitted at a time other than the above specific time point/period, the file size, time requirement, and feature information of the file to be transmitted need to be re-determined.

Optionally, after step 520, the first network element may send the filter and/or QoS parameters corresponding to the file to be transmitted to the third network element. In this way, the third network element can configure an appropriate transmission path for the file to be transmitted based on the filter and/or the QoS parameter, so as to transmit the file to be transmitted through the transmission path.

Here, the transmission path can be any transmission link that can transmit IP data packets, Ethernet data packets, and Unstructured data packets, such as QoS Flow, wireless bearer, PDU session, or public data network (Public Data Network, PDN) connection. The embodiment does not limit this. In addition, the third network element may be an SMF or a next-generation processing network element, which is not limited in this embodiment of the present application.

Specifically, the third network element may send relevant configuration information of the transmission path to the base station, the terminal device, and the UPF, so as to establish a transmission path for the file to be transmitted. In this way, after the transmission path is established and the wireless resources are prepared, the file to be transmitted starts to be transmitted.

The information processing method provided by the embodiment of the present application will be described in detail below with reference to specific examples.

Referring to the second schematic flow chart of the information processing method described in FIG. 5B , it includes the following steps:

Step 1. The PCF receives the request message.

Wherein, the request message includes file size information, time requirement information and characteristic information of the file to be transmitted.

In this embodiment of the present application, the request message in step 1 may be sent by the terminal device or by the application server.

Here, the file size information may include first file size information of the first subfile used for uplink transmission, and second file size information of the second subfile used for downlink transmission.

In addition, the time requirement information may be a round-trip time requirement of the file to be transmitted.

Step 2. The PCF determines the PCC rule based on the information in the request message.

In this embodiment of the present application, the PCC rules may include filters and QoS parameters corresponding to the files to be transmitted.

Specifically, the filter can be generated according to the feature information of the file to be transmitted in the request message. In addition, the QoS parameter may be determined according to the file size information and time requirement information of the file to be transmitted in the request message.

It should be noted that the QoS parameters can be specifically divided into UL and DL transmission parameters. Specifically, the PCF can determine the relevant transmission parameters of the uplink transmission and the downlink transmission according to the general requirements of the terminal device or the application server for the uplink transmission and the downlink transmission, and in combination with the actual wireless resource scheduling situation, so that the determined uplink transmission The transmission parameters related to the downlink transmission can meet the requirements of the terminal equipment or the application server.

Step 3. The PCF sends the PCC rule to the SMF.

Step 4: The SMF interacts with network element nodes such as the base station, UPF, and UE to bind the Qos flow and/or establish the corresponding Qos flow.

It should be understood that the SMF, the base station, the UPF and the UE can respectively determine the UL and DL QoS parameters and implement them in the corresponding QoS data flows.

It can be seen that in the information processing method provided by the embodiment of the present application, the PCF can independently determine the filter QoS parameters required for transmitting the file to be transmitted based on the file size, time requirements, and feature information of the file to be transmitted, thereby improving The flexibility of QoS parameter setting ensures the correct transmission of data. Moreover, the embodiment of the present application can also make full use of the existing PCC mechanism to manage the round-trip delay in the process of data transmission, and reduce the resource consumption of using time stamps for delay management in the prior art.

The following is a detailed introduction to the two transfer methods of the files to be transferred.

FIG. 6 is a first schematic flowchart of a data transmission method provided by an embodiment of the present application. As shown in FIG. 6 , the method includes the following steps 610 to 630 .

Step 610, the communication device acquires data packets corresponding to multiple sending files in the first data; each sending file includes one or more data packets.

Step 620, the communication device determines the transmission path used to transmit each sent file.

Step 630, the communication device transmits data packets corresponding to multiple sending files through multiple transmission paths; wherein, different transmission paths correspond to different QoS parameters.

Wherein, the communication device may be a terminal device, or a second network element. Further, the second network element may be a UPF or a next-generation processing network element, which is not limited in this embodiment of the present application.

Here, the first data may be application layer data.

It should be noted that the first data is uplink data, and may also be downlink data. Specifically, when the communication device is a terminal device, the first data may be uplink data, and when the communication device is a second network element, the first data may be downlink data.

In this embodiment of the present application, the communication device may identify data packets corresponding to multiple sent files from the first data. Wherein, the sending file may be a complete file, that is, a completed file in the traditional sense, such as a video file, an image file, and the like. The sending file may also be a part of a file, for example, a file corresponding to an I frame/B frame/P frame. The sending file may also be other forms of data, which is not limited in this embodiment of the present application.

Optionally, the sending file may be a one-way transmission file. In this embodiment of the present application, the file to be sent may be the first sub-file or the second sub-file among the files to be transmitted mentioned in the above embodiments.

It should be noted that different sending files may correspond to different data/content types. That is to say, different sent files correspond to different data/content types. For example, the first data may include three sending files, which are files corresponding to I frames, B frames, and P frames, respectively.

It should be understood that the QoS parameters corresponding to different sent files may be different. For example, a higher transmission rate may be required for sending files with higher latency requirements; and a higher transmission rate may not be required for sending files with lower latency requirements. Based on this, the communication device can identify and acquire the sending files in the first data, so as to provide different services for different sending files respectively.

In this embodiment of the present application, the sending file may include one or more data packets. That is to say, the data transmission method provided in the embodiment of the present application can perform data transmission at the granularity of files.

In the embodiment of the present application, the communication device may identify the first data in units of data packets. Specifically, the communication device may traverse each data packet of the first data, identify the sending file corresponding to each data packet, and finally obtain the corresponding sending file.

Optionally, in step 610, the communication device may specifically filter the first data through a plurality of filters to obtain data packets corresponding to the above-mentioned plurality of sending files.

It should be understood that the filter is used for the communication device to identify the data packet for sending the file from the user plane data packet (here, the first data). Wherein, multiple filters are associated with multiple sending files.

Optionally, there may be a one-to-one correspondence between the filter and the sent file, that is, one filter corresponds to one sent file. That is to say, a data packet corresponding to a sent file can be obtained by filtering through a filter.

Optionally, the communication device may use an existing data packet detection and/or data flow binding mechanism to identify and filter the first data through a filter, so as to obtain the data corresponding to multiple sent files of different data/content types. data pack. The communication device can also introduce a new protocol layer, such as an adaptation layer (or called an adaptation unit), to identify and filter the first data, and obtain data packets corresponding to multiple sent files of different data/content types.

It should be noted that the adaptation layer may be implemented in a modem (Modem), implemented in an operating system (Operating System, OS), or implemented in an application layer, which is not limited in this embodiment of the present application.

For example, refer to the schematic diagram of the protocol layer architecture of the communication device shown in FIG. 7 . On the terminal device side, the adaptation layer can be located between the application layer and the 5G access network protocol layer. On the UPF side, the adaptation layer can be located at the upper layer of the GTP-U layer, and process the data packets processed by the GTP-U.

In the embodiment of the present application, after obtaining data packets corresponding to multiple sending files, the communication device may bind data packets corresponding to different sending files to different transmission paths. That is to say, the communication device can use different transmission paths to transmit data packets corresponding to different sending files, and the QoS parameters corresponding to each transmission path are different, so as to ensure the QoS requirements of different sending files.

Optionally, the transmission path can be any transmission link that can transmit IP data packets, Ethernet data packets, and Unstructured data packets, such as QoS Flow, wireless bearer, PDU session, or public data network (Public Data Network, PDN) connection, This embodiment of the present application does not limit this.

In this embodiment of the present application, different transmission paths may correspond to different QoS parameters.

Optionally, the QoS parameter may include at least one of the following: transmission rate of uplink transmission, transmission rate of downlink transmission, transmission delay of uplink transmission, transmission delay of downlink transmission, packet loss rate of uplink transmission, downlink transmission packet loss rate, packet error rate of uplink transmission, packet error rate of downlink transmission, ARP, resource type, scheduling priority, and average time window, etc.

That is to say, the communication device may split the first data on one side (for example, on the terminal device or UPF side) according to the feature information (such as data type and/or content type) of the file, and split the multiple The data packets corresponding to each file are bound to different transmission paths (such as QoS flows), and are transmitted through different transmission paths, and the QoS parameters corresponding to different transmission paths are different.

Correspondingly, the receiving end may combine data packets received on different transmission paths. The receiving end can also send the combined data to the next node, or the application layer of this node. Alternatively, the receiving end may not combine the data packets from different transmission paths, but mark the data packets from different transmission paths. Further, the receiving end may send the marked data to the next node, or the application layer of the current node.

In an example, as shown in FIG. 8A , the first data may be a video file taken by the terminal device, and the application layer in the terminal device may send the video file to the adaptation layer, and then the adaptation layer may process the video file Recognition and splitting are performed to separate data packets corresponding to three different sending files, which are I-frame files, B-frame files, and P-frame files. The adaptation layer can send the obtained data packets corresponding to the three different sending files to the UPF through three different transmission paths (such as QoS flows).

Correspondingly, the UPF receives the data transmitted on three different transmission paths, and can combine the data packets of different transmission paths through the adaptation layer, and transmit the combined data to the next node of the UPF (such as application server). Or, the UPF can mark the data packets of different transmission paths, so as to mark the transmission path corresponding to each data packet, and further, the UPF transmits the data obtained after adding the mark to the next node (such as an application server).

In another example, as shown in FIG. 8B, the first data may be a video file with content recognition results added, and the UPF may receive the first data sent by the application server. In this way, the UPF adaptation layer may The data is identified and split to obtain data packets corresponding to three sending files, and the three files may be an I frame file, a B frame file, and a P frame file. The adaptation layer can send the divided data packets corresponding to the three different sending files to the terminal device through three different transmission paths (such as QoS flows).

Correspondingly, after the terminal device receives data packets transmitted on three different transmission paths, it can combine the data packets from different transmission paths through the adaptation layer of the terminal device, and transmit the combined data to the terminal device application layer. Alternatively, the terminal device may mark data packets from different transmission paths, and transmit the marked data to the application layer of the terminal device.

In some embodiments, the data transmission method may also include the following steps:

The communication device receives data packets corresponding to multiple received files through multiple transmission paths;

The communication device combines the data packets corresponding to the multiple received files to obtain the second data.

That is to say, the communication device may also receive data packets corresponding to multiple received files transmitted by the sending end through different transmission paths, and combine the received data packets corresponding to multiple received files to obtain the second data.

Optionally, the communication device may use the adaptation layer to combine data packets transmitted by different transmission paths, and transmit the combined data to the next node of the communication device, or the application layer of the communication device.

It can be seen that, in the data transmission method provided by the embodiment of the present application, the communication device can identify the data packets corresponding to multiple different sending files in the application layer data, and pass the data packets corresponding to the identified multiple sending files through different transmission path to meet the quality of service requirements of different sent files.

In the embodiment of the present application, the filter associated with the sent file and the QoS parameters corresponding to the sent file can be determined through the information carried in the request message in the above embodiment.

Here, the first transmission file among the multiple transmission files will be described. Wherein, the first sending file may be any sending file among multiple sending files.

Optionally, the QoS parameter corresponding to the first sent file, and/or, the filter associated with the first sent file is determined based on the request message; the request message is used to request the transmission of the file to be transferred based on the demand information; here, The first sending file is the first sub-file or the second sub-file in the file to be transmitted; the requirement information includes at least one of the file size information, time requirement information, and feature information of the file to be transmitted; the time requirement information It is used to indicate the maximum time to complete the transmission of the pending file; the feature information is used to identify and/or detect the data packets in the pending file.

It can be understood that the QoS parameter corresponding to the first sent file and/or the filter associated with the first sent file may be determined by the first network element and sent to the current communication device by the first network element .

Specifically, the first network element may receive a request message requesting to transmit a file to be transmitted, and determine the file to be transmitted based on at least one of file size information, time requirement information, and feature information included in the request message. (It can also be considered as the filter and/or QoS parameter of the first sent file).

It should be noted that the process of the first network element determining the filter and/or QoS parameters corresponding to the file to be transmitted based on the request message is the same as the above embodiment, and for the sake of brevity, details are not repeated here.

Optionally, after obtaining the filter and/or QoS parameters, the first network element (such as PCF) may forward the filter and/or QoS corresponding to the file to be transmitted to the communication device through a third network element (such as SMF). parameter. In this way, after receiving the filter and/or QoS parameters corresponding to the file to be transmitted, the communication device can use the filter to identify the data packet corresponding to the first sent file from the data packets of the first data, and send the first The data packets of the file are transmitted through the first QoS flow matching the aforementioned QoS parameters, so as to meet the quality of service requirement of the first sent file.

FIG. 9 is a second schematic flowchart of the data transmission method provided by the embodiment of the present application. As shown in FIG. 9 , the method includes the following contents.

Step 910, the communication device adds tag information to each data packet in the first data to obtain the third data; the tag information is used to indicate the sending file to which the data packet belongs.

Step 920, the communication device transmits the third data through a transmission path; wherein, data packets in the third data belonging to different sending files correspond to different QoS parameters (even if transmitted through the same transmission path).

Here, the communication device may be a terminal device, or a second network element. Wherein, the second network element may be a UPF, or a next-generation processing network element, which is not limited in this embodiment of the present application.

In this embodiment of the present application, the first data may be application layer data.

It should be noted that the first data may be uplink data or downlink data. Specifically, when the communication device is a terminal device, the first data may be uplink data, and when the communication device is a second network element, the first data may be downlink data.

In this embodiment of the present application, the sending file may be a complete file, that is, a completed file in the traditional sense, such as a video file, an image file, and the like. The sending file may also be a part of a file, for example, a file corresponding to an I frame/B frame/P frame. The sending file may also be other forms of data, which is not limited in this embodiment of the present application.

Optionally, the sent file may be a file for one-way transmission (such as upstream transmission or downstream transmission). In this embodiment of the present application, the file to be sent may be the first sub-file or the second sub-file among the files to be transmitted mentioned in the above embodiments.

It should be noted that different sending files may have different data/content types. That is to say, different sent files correspond to different data/content types. For example, the first data may include three sending files, which are files corresponding to I frames, B frames, and P frames, respectively.

It should be understood that the QoS parameters corresponding to different sent files may be different. For example, a higher transmission rate may be required for sending files with higher latency requirements; and a higher transmission rate may not be required for sending files with lower latency requirements. Based on this, the communication device can identify the sending file (also known as a file type) to which each data packet in the first data belongs, so as to provide different services for different sending files (file types).

In this embodiment of the present application, the communication device may identify each data packet in the first data in units of data packets, determine the sending file to which each data packet belongs, and obtain tag information corresponding to each data packet.

Optionally, in step 910, the communication device may specifically filter the data packets in the first data through a plurality of filters, and determine the tag information corresponding to each data packet. The sending file to which the current data packet belongs is indicated by the tag information.

It should be understood that the filter is used by the communication device to identify data packets of different sent files from the application layer data (such as the above first data). Wherein, multiple filters are associated with multiple sending files.

Optionally, there may be a one-to-one correspondence between the filter and the sent file, that is, one filter corresponds to one sent file. That is to say, a sending file can be obtained by filtering through a filter.

Optionally, the communication device may use an existing data packet detection and/or data flow binding mechanism to identify and filter the first data, and determine the sending file to which each data packet in the first data belongs. The communication device can also introduce a new protocol layer, such as an adaptation layer (or called an adaptation unit) to identify and filter the first data, determine the sending file to which each data packet in the first data belongs, and obtain the data packet corresponding label information.

It should be noted that the adaptation layer may be implemented in the Modem, in the OS, or in the application layer, which is not limited in this embodiment of the present application.

For example, refer to the schematic diagram of the protocol layer architecture of the communication device shown in FIG. 7 . On the terminal device side, the adaptation layer can be located between the application layer and the 5G access network protocol layer. On the UPF side, the adaptation layer may be located between the GTP-U layer and the application layer.

In the embodiment of the present application, after the communication device determines the sending file to which each data packet belongs, it can add tag information to each data packet in the first data, and mark the sending file to which each data packet belongs through the tag information, thereby obtaining third data. That is to say, each data packet in the third data has tag information, and the tag information is specifically used to indicate the sending file to which the current data packet belongs. For example, the tag information may be identification information of the sending file to which the current data packet belongs.

Further, the communication device may bind the data packets of the third data to the same transmission path for transmission, and when the third data is transmitted through the transmission path, the QoS corresponding to the data packets in the third data belonging to the different sending files The parameters are different (even if the data packets in the third data are all transmitted through one transmission path), so as to ensure the QoS requirements of different sending files.

Optionally, the transmission path can be any transmission link that can transmit IP data packets, Ethernet data packets, and Unstructured data packets, such as QoS Flow, radio bearer, PDU session, or PDN connection, which is not limited in the embodiment of the present application .

Exemplarily, the first data may be a video file taken by the terminal device. Referring to FIG. 10, the application layer in the terminal device may send the first data to the adaptation layer, and then the adaptation layer of the terminal device may identify the For each data packet in the data, determine whether the file to which each data packet belongs is an I-frame file, a B-frame file, or a P-frame file. And based on the identification result of each data packet, tag information is added to the corresponding data packet, so as to obtain the third data. The adaptation layer of the terminal device may bind the third data added with tag information to the same transmission path and send it to the UPF. Here, data packets belonging to different files in the transmission path have different corresponding QoS parameters.

Correspondingly, after the UPF receives the third data sent by the terminal device, the UPF adaptation layer can merge/reorder the data packets in the third data based on the label information corresponding to each data packet in the third data processing, and de-labeling processing, and transmit the processed data to the next node of the UPF (such as an application server).

The communication device receives the fourth data; each data packet in the fourth data carries label information corresponding to the data packet;

Based on the label information of each data packet in the fourth data, the communication device combines and/or reorders the data packets in the fourth data to obtain the second data.

That is to say, the communication device can also receive the fourth data from the communication device on the opposite side through a transmission path, and based on the tag information corresponding to each data packet in the fourth data, combine the data packets with the same tag information and Reorder processing to obtain the second data.

Optionally, the communication device may use the adaptation layer to merge and/or reorder the fourth data, and transmit the processed data to a next node of the communication device, or to an application layer of the communication device.

It can be seen that, in the data transmission method provided by the embodiment of the present application, the communication device can add label information to each data packet in the first data to obtain the third data, and then bind the third data to a transmission path The transmission is performed, and the QoS parameters corresponding to the data packets of different sent files in the third data are different, so as to meet the service quality requirements of different sent files.

Here, the first transmission file among the multiple transmission files will be described. The first sending file may be any sending file among a plurality of sending files.

Optionally, the QoS parameter corresponding to the first sent file, and/or, the filter associated with the first sent file is determined based on the request message; the request message is used to request the transmission of the file to be transferred based on the demand information; wherein, The first sending file can be the first sub-file in the file to be transmitted, or the second sub-file; the demand information includes at least one of the file size information, time requirement information, and feature information of the file to be transmitted; the time requirement information It is used to indicate the maximum time to complete the transmission of the pending file; the feature information is used to identify and/or detect the data packets in the pending file.

Here, the QoS parameters corresponding to the first sending file and/or the filters associated with the first sending file are determined by the first network element and sent to the communication device.

Specifically, the first network element may receive the request message, and based on at least one item of file size information, time requirement information, and feature information of the file to be transmitted included in the request message, determine the filter and/or or QoS parameters.

It should be noted that the process of determining the filter and/or QoS parameters corresponding to the file to be transmitted based on the request message is the same as the above-mentioned embodiment, and for the sake of brevity, details are not repeated here.

Further, the first network element (for example, PCF) may forward the filter and/or QoS parameters of the file to be transmitted to the communication device through a third network element (for example, SMF). In this way, after receiving the filter and/or QoS parameters corresponding to the file to be transmitted, the communication device can use the filter to determine and mark the transmission file to which each data packet in the first data belongs, and bind the marked data to Set to a transmission path for transmission. Moreover, different QoS parameters are set for data packets belonging to different sending files during transmission.
