It should be noted that fig. 1 is only an exemplary system to which the present application is applicable, and of course, the method shown in the embodiment of the present application may be applicable to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship. It should also be understood that, in the embodiments of the present application, the "indication" may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B. It should also be understood that "corresponding" mentioned in the embodiments of the present application may mean that there is a direct correspondence or an indirect correspondence between the two, may mean that there is an association between the two, and may also be a relationship between an instruction and an indicated, configured, or the like. It should also be understood that "predefined" or "predefined rules" mentioned in the embodiments of the present application may be implemented by pre-storing corresponding codes, tables or other manners in which related information may be indicated in devices (including, for example, terminal devices and network devices), and the present application is not limited to the specific implementation thereof. Such as predefined may refer to what is defined in the protocol. It should be further understood that, in the embodiment of the present application, the "protocol" may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited by the present application.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

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

For example, in artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) applications, a multi-level AI process is generally adopted to improve data analysis efficiency and user experience. The multi-stage AI process is understood as data processing performed by the terminal device and the network measurement network element separately. Specifically, referring to a multi-level AI processing application scenario schematic diagram shown in fig. 2, when an image recognition function is to be implemented, a terminal device may perform a partial operation on a captured image to obtain intermediate state data; further, the terminal device may send the intermediate data to the application server through the communication network for further calculation, and the final application server identifies that the photographed image is "a cat", and returns the identification result to the terminal device through the communication network.

It should be appreciated that in the AI reasoning scenario described above, there is a need to keep track of the total time of the data round trip. Referring to fig. 3, the total time of the data round trip may include: the processing time of the terminal device, the uplink transmission time of intermediate state data from the terminal device to the application server, the data processing time of the application server, and the downlink transmission time of the identification result from the application server to the terminal device. That is, in the AI reasoning scenario, if the recognition result of the photographed image is required to be obtained within 1 second, it means that the total time period from the photographed image to the recognition result obtained from the application server by the terminal device is 1 second.

In practical application, a QoS model in the 5G technology can be utilized to ensure the transmission requirement of data. Referring to the QoS model shown in fig. 4, the terminal device and the UPF may map application layer data to a plurality of QoS flows for transmission, each QoS flow corresponding to a different QoS parameter.

Here, as an important measure of communication quality, qoS parameters are generally used to indicate the characteristics of QoS flows, and may include, but are not limited to: 5G QoS identification (5G QoS index,5 qi), allocation and retention priority (Allocation And Retention Priority, ARP), guaranteed bit rate (Guaranteed Flow Bit Rate, GFBR), maximum traffic bit rate (Maximum Flow Bit Rate, MFBR), maximum packet loss rate (Maximum Packet Loss Rate), packet delay Budget (PACKET DELAY bridge, 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 amount (Maximum Data Burst Volume), UE aggregate maximum bit rate (UE-AMBR), session aggregate maximum bit rate (Session-AMBR), etc.

In the embodiment of the present application, the UPF and the terminal device may pre-determine a Filter (i.e. a Filter, or referred to as a service data flow template), where the Filter may be a trapezoid on the left side and a parallelogram on the right side in fig. 4. Wherein the filter may comprise parameters describing the characteristics of the data packet. Specifically, the UPF and the terminal device may use a filter to filter out uplink or downlink data packets that conform to the characteristics of the data packet, and bind the uplink or downlink data packets to a certain QoS flow for transmission.

In general, the terminal device or the application server directly sets up the required parameters such as uplink/downlink transmission rate, uplink/downlink packet loss rate, etc., so that the network element on the network side can construct QoS flows based on the required parameters. However, in fact, the available resources on the network side are not constant, and in some cases cannot meet the requirements of the terminal device, which leads to a problem of transmission failure.

Based on this, the embodiment of the application provides an information processing method, specifically, a first network element may receive a request message; the request message comprises the requirement information of the file to be transmitted; the request message is used for requesting to transmit the file to be transmitted based on the requirement information; the file to be transmitted comprises one or more data packets; the requirement information comprises at least one piece of file size information, time requirement information and characteristic information of the file to be transmitted, and the first network element determines a filter and/or QoS parameters for the file to be transmitted based on at least one piece of file size information, time requirement information and characteristic information. That is, the first network element may autonomously determine a filter and/or QoS parameters required for transmitting the pending file based on the file size, the time requirement, and the feature information of the pending file, so as to improve flexibility of QoS related parameter setting, thereby ensuring correct transmission of data.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 5A is a flowchart illustrating a method for processing information according to an embodiment of the present application, as shown in fig. 5A, the method includes the following steps 510 and 520.

Step 510, the first network element receives a request message; the request message comprises the requirement information of the file to be transmitted; the request message is used for requesting the first network element to transmit the file to be transmitted based on the demand information; the demand information may include at least one of file size information, time demand information, and feature information of the file to be transferred.

Alternatively, the first network element may be a policy control (Policy Control Function, PCF) network element, or a next generation processing network element, which the embodiments of the present application do not limit.

Optionally, the request message may be sent by the terminal device to the first network element, or may be sent by the application server to the first network element, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the file to be transferred may be a complete file, such as a complete file in a conventional sense, for example, a video file, an image file, etc. The file to be transmitted may also be a part of a file, for example, the file to be transmitted may be a file corresponding to a key frame (i.e. an I frame) in a video stream, or a bi-directionally predicted interpolated encoded frame (i.e. a B frame), or a forward predicted encoded frame (i.e. a P frame). The file to be transferred may also be other data, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the file to be transmitted may be a set of data packets, that is, the file to be transmitted includes one or more data packets.

Here, the data packet may refer to an internet protocol (Internet Protocol, IP) data packet, an Ethernet (Ethernet) data packet, or an Unstructured (Unstructured) data packet, to which the embodiment of the present application is not limited.

It can be understood that the information processing method provided by the embodiment of the application can be performed with the file as granularity.

Optionally, the file to be transmitted may include a first sub-file for uplink transmission and/or a second sub-file for downlink transmission.

For example, taking the application scenario shown in fig. 2 as an example, the first subfile may be intermediate state data obtained by partially processing the shot image by the terminal device, and the second subfile may be an identification result obtained by identifying the shot image by the application server.

In the embodiment of the application, the request message can include file size information, time requirement information and characteristic information of the file to be transmitted.

Alternatively, the file size information may include first file size information, and/or second file size information. The first file size information is used for indicating the size of the first subfile; and second file size information indicating a size of the second subfile.

It should be understood that, if the file to be transmitted includes only the first subfile for uplink transmission, the file size information may include first file size information indicating the size of the first subfile; if the pending file includes only the second sub-file for downlink transmission, the file size information may include second file size information indicating the size of the second sub-file.

If the file to be transmitted includes the first subfile and the second subfile, the file size information of the file to be transmitted may be indicated according to UpLink (UL) and DownLink (DL), respectively. That is, the file size information may be through two different information: and if the first file size information and the second file size information respectively indicate the file size of the first sub-file and the file size of the second sub-file. For example, the file size information may include two parameters: 100 megabytes and 5 megabytes indicate an upstream file size of 100 megabytes and a downstream file size of 5 megabytes, respectively.

If the file to be transferred includes the first sub-file and the second sub-file, the file sizes of the first sub-file and the second sub-file can be indicated at the same time by the same information. That is, the first file size information and the second file size information may be the same information. For example, the file size information of the file to be transferred may include a parameter: 50 megabytes, i.e., the file size of the first subfile and the file size of the second subfile are 50 megabytes.

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

Alternatively, the time requirement information may be specifically used to indicate the longest time (or referred to as an upper time limit) for transmitting the file to be transmitted in the uplink and/or downlink direction between the terminal device and the second network element, or the time requirement information may be used to indicate the longest time (or referred to as an upper time limit) for completing transmission of the file to be transmitted in the uplink and/or downlink direction between the terminal device and the application server.

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

It should be appreciated that the time requirement information may be represented by a point in time that represents the last time the transmission of the pending file was completed. The time requirement information may also be represented by a time length (e.g., a time period) that is a time length taken from the start of transmission of the file to the completion of transmission, for example, a time length from the first packet to the last packet corresponding to the file to be transmitted.

It should be noted that the time requirement information may be a time requirement for unidirectional transmission (uplink transmission or downlink transmission) of the file to be transmitted, or may be a time requirement for round trip transmission of the file to be transmitted, for example, the time requirement information may be a total time requirement of uplink transmission and downlink transmission. The embodiments of the present application are not limited in this regard.

Optionally, in some embodiments, the time requirement information may include first time requirement information, and/or second time requirement information; the first time requirement information is used for indicating the time requirement of transmitting the first subfile; the second time requirement information is used to indicate a time requirement for transmitting the second subfile.

It should be understood that, if the file to be transmitted includes only the first subfile for uplink transmission, the time requirement information may include first time requirement information indicating a time requirement for transmitting the first subfile; if the file to be transmitted includes only the second subfile for downlink transmission, the time requirement information may include second time requirement information indicating a time requirement of the second subfile.

For example, referring to the protocol layer architecture diagram shown in fig. 7, when the time requirement information indicates the longest time for completing transmission of the file to be transmitted in the uplink direction and/or the downlink direction between the terminal device and the UPF, the first time requirement information may include a total time of one or more of the following: the terminal equipment 5G access network protocol layer receives all or part of the data packet corresponding to the first subfile from the application layer, the 5G access network protocol layer processes the obtained data packet, the processed data packet is processed and sent to the UPF through the 5G access network, and the UPF receives the time of the user plane general packet radio service protocol (GENERAL PACKET Radio Service Tunneling Protocol, GTP-U) data packet. The additional first time requirement information may further include a time when the UPF decapsulates the received GTP-U data packet and/or sends it out to the next node (e.g., application server) through the UPF egress.

The second time requirement information may include a total time of one or more of: and the GTP-U layer of the UPF processes the data packet corresponding to the second sub-file, sends the processed data packet to the 5G access network protocol layer of the terminal equipment through the 5G access network, and sends the processed data packet to the application layer of the terminal equipment after being analyzed by the 5G access network protocol layer of the terminal equipment.

If the time requirement information is specifically used for indicating the longest time for completing the transmission of the pending file in the uplink direction and/or the downlink direction between the terminal device and the application server, the first time requirement information may include: and sending the data packet corresponding to the first subfile from the application layer of the terminal equipment to the time for receiving and/or processing the data packet by the application layer of the application server. The second time requirement information may include: and sending the data packet corresponding to the second subfile from the application layer of the application server to the time for receiving and/or processing the data packet by the application layer of the terminal equipment.

It should be noted that, the adaptation layer shown in fig. 7 may be a newly introduced protocol layer, which is described in the following embodiments, and will not be described herein.

If the file to be transmitted includes the first subfile and the second subfile, the time requirement information of the file to be transmitted can be indicated according to UL and DL respectively. That is, the time requirement information may be obtained by two different pieces of information: such as first time requirement information and second time requirement information, respectively indicating the time requirement of the first subfile and the time requirement of the second subfile. For example, the time requirement information may include two parameters: 0.8 seconds and 0.2 seconds indicate that the time to transmit the uplink file is less than or equal to 0.8 seconds and the time to transmit the downlink file is less than or equal to 0.2 seconds, respectively.

If the file to be transferred includes the first sub-file and the second sub-file, the time requirements of the first sub-file and the second sub-file can be indicated at the same time through the same information. That is, the first time requirement information and the second time requirement information may be the same information. For example, the time requirement information may include a parameter: 0.5 seconds, that is, the time required to transfer the first subfile and the time to transfer the second subfile are both less than or equal to 0.5 seconds.

Alternatively, in other embodiments, the time requirement information may include third time requirement information, where the third time requirement information is used to indicate a total time requirement for transmitting the first subfile and the second subfile.

For example, the time requirement information may include a parameter: 1 second, i.e. the time requirement for transmitting the first subfile and the total time of the second subfile is less than or equal to 1 second.

In the embodiment of the application, the characteristic information can be used for identifying and/or detecting the data packet corresponding to the file to be transmitted. The feature information may be information specific to the file to be transmitted and may be information capable of distinguishing from other files, for example, the feature information may be IP address/port number, or Service Type (Type of Service) information carried on an IP header, or a data Type and/or a content Type of the file to be transmitted, which is not limited in the embodiment of the present application.

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

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

In the embodiment of the application, the filter can also be called as an SDF template and is used for describing the characteristics of the data packet corresponding to the file to be transmitted. It can be appreciated 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.

Alternatively, the filter may be determined based on the characteristic information in the request message. That is, after receiving the request message, the first network element may determine, based on the feature information of the pending file carried by the request message, a filter corresponding to the pending file. In this way, during the service data transmission process, the data transmitting end can identify the data packet corresponding to the file to be transmitted from the user plane data packets based on the filter.

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

QoS identification information;

the transmission rate of the uplink transmission;

A transmission rate of the downlink transmission;

Transmission delay of uplink transmission;

transmission delay of downlink transmission;

Packet loss rate of uplink transmission;

packet loss rate of downlink transmission;

The packet error rate of the uplink transmission;

The packet error rate of the downlink transmission;

ARP；

A resource type;

Scheduling priority;

Average time window.

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

In the embodiment of the present application, the first network element may distinguish between uplink transmission and downlink transmission, and determine parameters corresponding to UL and DL, for example, a transmission rate of uplink transmission, a transmission rate of downlink transmission, a transmission delay of uplink transmission, a transmission delay of downlink transmission, a packet loss rate of uplink transmission, a packet loss rate of downlink transmission, a packet error rate of uplink transmission, a packet error rate of downlink transmission, and so on.

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

In addition, the transmission delay of the uplink transmission may include parameters such as AN uplink PDB and/or AN uplink AN-PDB, and correspondingly, the transmission delay of the downlink transmission may include parameters such as a downlink PDB and/or a downlink AN-PDB, which is not limited in the embodiment of the present application.

It may be understood that, if the file to be transmitted includes only the first subfile for uplink transmission, the QoS parameters may include relevant transmission parameters for uplink transmission, for example, a transmission rate of uplink transmission, a transmission delay of uplink transmission, a packet loss rate of uplink transmission, or a packet error rate of uplink transmission. If the file to be transmitted includes only the second subfile for downlink transmission, the QoS parameters may include related transmission parameters for downlink transmission, for example, a transmission rate of downlink transmission, a transmission delay of downlink transmission, a transmission packet loss rate of downlink transmission, or a packet error rate of downlink transmission. In addition, if the file to be transmitted includes the first subfile and the second subfile, the QoS parameters may include parameters for uplink and downlink, for example, transmission rates of uplink and downlink, transmission delays of uplink and downlink, packet loss rates of uplink and downlink, or packet error rates of uplink and downlink.

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

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

In the embodiment of the application, for the case that the file to be transmitted includes the first subfile and the second subfile, the first network element can respectively determine the relevant transmission parameters of the uplink transmission and the downlink transmission according to the total requirement of the third party (such as the terminal equipment or the application server) on the uplink transmission and the downlink transmission and combining with the actual radio resource scheduling condition, so that the determined relevant transmission parameters of the uplink transmission and the downlink transmission can meet the requirement of the third party.

For example, the first subfile size is 100 megabytes, the second subfile size is 5 megabytes, and the round trip time requirement is 5 seconds. If there are fewer uplink resources and more downlink resources currently available, the first network element may set the transmission rate of the uplink transmission to 25mbps, that is, 100 megas/4 s; the transmission rate of the downlink transmission is configured to be 5mbps, that is, 5 megabits/1 second. If there are more uplink resources available and fewer downlink resources available, the first network element may set the transmission rate of the uplink transmission to 50mbps, that is, 100 megas/2 s; the transmission rate of the downlink transmission is configured to be 1.67mbps, that is, 5 megabits/3 seconds. It should be understood that the uplink transmission rate and the downlink transmission rate may be other values as long as the file size information and the time requirement information are satisfied.

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

It should be noted that, the request message may carry the requirement information of one or more files to be transmitted, and the embodiment of the present application does not limit the number of requirement information carried in the request message. It may be understood that, when the request message carries the requirement information of the plurality of files to be transmitted, the first network element may determine, according to the request message, a filter and/or QoS parameter corresponding to the plurality of files to be transmitted, and the filter and/or QoS parameter corresponding to different files to be transmitted may be different.

It should also be noted that the file to be transmitted may be a file for transmission at a specific point in time/period. That is, when the file is transmitted at a time other than the above specific point/period, it is necessary to newly determine the file size, time requirement, and characteristic information of the file to be transmitted.

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

Here, the transmission path may be any transmission link capable of transmitting an IP packet, an Ethernet packet, and an Unstructured packet, such as a QoS Flow, a radio bearer, a PDU session, or a public data network (Public Data Network, PDN) connection, which is not limited in the embodiment of the present application. In addition, the third network element may be an SMF, or may be 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 the transmission path for the pending file. Thus, after the transmission path is established and the radio resource is prepared, the file to be transmitted starts to be transmitted.

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

A second flow chart of the information processing method described with reference to fig. 5B includes the following steps:

step 1, PCF receives the request message.

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

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

Here, the file size information may include first file size information of a first sub-file for uplink transmission and second file size information of a second sub-file for downlink transmission.

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

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

In the embodiment of the application, the PCC rule can comprise a filter and QoS parameters corresponding to the file to be transmitted.

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

The QoS parameters may be specifically classified into UL and DL transmission parameters. Specifically, the PCF may determine relevant transmission parameters of uplink transmission and downlink transmission according to the total requirement of the terminal device or the application server for uplink transmission and downlink transmission, and in combination with an actual radio resource scheduling situation, so that the determined relevant transmission parameters of uplink transmission and downlink transmission can meet the requirement of the terminal device or the application server.

And step 3, the PCF sends the PCC rule to the SMF.

And 4, the SMF interacts with network element nodes such as a base station, UPF, UE and the like to bind Qos flows and/or establish corresponding Qos flows.

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

Therefore, in the information processing method provided by the embodiment of the application, the PCF can autonomously determine the QoS parameters of the filter required for transmitting the file to be transmitted based on the file size, the time requirement and the characteristic information of the file to be transmitted, and the flexibility of QoS parameter setting is improved, so that the correct transmission of data is ensured. In addition, the embodiment of the application can fully utilize the existing PCC mechanism to manage the round trip delay in the data transmission process, and reduce the resource consumption for time delay management by utilizing the time stamp in the prior art.

The following describes in detail two transmission modes of the file to be transmitted.

Fig. 6 is a flowchart illustrating a data transmission method according to 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 obtains data packets corresponding to a plurality of transmission files in the first data; each transmission file includes one or more data packets.

Step 620, the communication device determines a transmission path used to transmit each of the transmission files.

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

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 by the embodiment of the present application.

Here, the first data may be application layer data.

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 the embodiment of the application, the communication equipment can identify and obtain the data packets corresponding to the plurality of sending files from the first data. The transmission file may be a complete file, i.e. a complete file in the conventional sense, such as a video file, an image file, etc. The transmission file may be a part of a file, for example, a file corresponding to an I frame/B frame/P frame. The transmission file may also be other forms of data, which the embodiments of the present application do not limit.

Alternatively, the transmission file may be a unidirectionally transmitted file. In the embodiment of the present application, the transmission file may be the first sub-file or the second sub-file in the pending file mentioned in the above embodiment.

It should be noted that different transmission files may correspond to different data/content types. That is, different transmission files correspond to different data/content types. For example, the first data may include three transmission files, I-frame, B-frame, and P-frame corresponding files, respectively.

It should be appreciated that the QoS parameters corresponding to different transmission files may be different. For example, higher transmission rates may be required for higher latency requirements for the transmitted file; while higher transmission rates may not be required for transmitted files with lower latency requirements. Based on this, the communication device can recognize and acquire the transmission file in the first data, thereby providing different services for different transmission files, respectively.

In the embodiment of the application, the sending file may include one or more data packets. That is, the data transmission method provided by the embodiment of the application can perform data transmission with the file as granularity.

In the embodiment of the application, the communication device can identify the first data by taking the data packet as a unit. Specifically, the communication device may traverse each data packet of the first data, identify a transmission file corresponding to each data packet, and finally obtain a corresponding transmission file.

Optionally, in step 610, the communication device may specifically perform filtering processing on the first data through a plurality of filters to obtain data packets corresponding to the plurality of sending files.

It will be appreciated that the filter is used by the communication device to identify the data packet from which the file was sent from the user plane data packet (here the first data). Wherein, a plurality of filters have association relation with a plurality of transmission files.

Alternatively, there may be a one-to-one correspondence between filters and sendfiles, i.e., one filter for each sendfile. That is, a data packet corresponding to a transmission file can be obtained by filtering through a filter.

Optionally, the communication device may utilize an existing packet detection and/or data flow binding mechanism to identify and filter the first data through a filter, so as to obtain packets corresponding to the transmission files of multiple different data/content types. The communication device may 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 a plurality of data packets corresponding to the transmission files with different data/content types.

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

Exemplary, reference is made to the communication device protocol layer architecture schematic shown in fig. 7. On the terminal device side, the adaptation layer may be located between the application layer and the 5G access network protocol layer. On the UPF side, the adaptation layer may be located at a layer above the GTP-U layer, and processes the data packet processed by the GTP-U.

In the embodiment of the application, after the communication equipment obtains the data packets corresponding to the plurality of sending files, the data packets corresponding to the different sending files can be respectively bound to different transmission paths. That is, the communication device may use different transmission paths to transmit data packets corresponding to different transmission files, and QoS parameters corresponding to each transmission path are different, so as to ensure QoS requirements of different transmission files.

Alternatively, the transmission path may be any transmission link capable of transmitting IP packets, ethernet packets, and Unstructured packets, such as QoS flows, radio bearers, PDU sessions, or public data network (Public Data Network, PDN) connections, which the embodiments of the present application are not limited to.

In the embodiment of the application, different transmission paths can correspond to different QoS parameters.

Optionally, the QoS parameters may include at least one of: the method comprises the steps of uplink transmission rate, downlink transmission rate, uplink transmission time delay, downlink transmission time delay, uplink packet loss rate, downlink packet loss rate, uplink packet error rate, downlink packet error rate, ARP, resource type, scheduling priority, average time window and the like.

That is, the communication device may split the first data according to the characteristic information (e.g., data type and/or content type) of the file on a single side (e.g., on the terminal device or the UPF side), bind the data packets corresponding to the split files to different transmission paths (e.g., qoS flows), transmit the data packets through the different transmission paths, and have different QoS parameters corresponding to the different transmission paths.

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

In an example, referring to fig. 8A, the first data may be a video file captured by a terminal device, an application layer in the terminal device may send the video file to an adaptation layer, and then the adaptation layer may identify and split the video file, and separate data packets corresponding to three different sending files, which are an I-frame file, a B-frame file, and a P-frame file, respectively. The adaptation layer may 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 data transmitted on three different transmission paths can be received by the UPF, the data packets of the different transmission paths can be combined through the adaptation layer, and the combined data is transmitted to the next node (such as an application server) of the UPF. Or the UPF may mark the data packets of different transmission paths to mark the transmission path corresponding to each data packet, and further, the UPF transmits the data obtained after adding the mark to a next node (such as an application server).

In another example, referring to fig. 8B, the first data may be a video file to which a content identification result is added, and the UPF may receive the first data sent by the application server, so that an adaptation layer of the UPF may identify and split the first data to obtain data packets corresponding to three sending files, where the three files may be an I-frame file, a B-frame file, and a P-frame file. The adaptation layer may send the packets corresponding to the split three different sending files to the terminal device through three different transmission paths (such as QoS flows).

Correspondingly, after receiving the data packets transmitted on the three different transmission paths, the terminal device can combine the data packets from the different transmission paths through the adaptation layer of the terminal device, and transmit the combined data to the application layer of the terminal device. Or the terminal device may mark the 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 further include the steps of:

The communication equipment receives data packets corresponding to a plurality of received files through a plurality of transmission paths;

and the communication equipment performs combination processing on the data packets corresponding to the plurality of received files to obtain second data.

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

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

Therefore, in the data transmission method provided by the embodiment of the application, the communication device can identify the data packets corresponding to the plurality of different sending files in the application layer data, and transmit the identified data packets corresponding to the plurality of sending files through different transmission paths so as to meet the service quality requirements of the different sending files.

In the embodiment of the present application, the filter associated with the transmission file and the QoS parameter corresponding to the transmission file may be determined by the information carried in the request message in the above embodiment.

Here, a description will be given of a first transmission file among a plurality of transmission files. The first transmission file may be any one of a plurality of transmission files.

Optionally, qoS parameters corresponding to the first transmission file and/or a filter having an association relationship with the first transmission file is determined based on the request message; the request message is used for requesting to transmit the file to be transmitted based on the demand information; here, the first sending file is a first sub-file or a second sub-file in the file to be transmitted; the requirement information comprises at least one item of file size information, time requirement information and characteristic information of the file to be transmitted; the time requirement information is used for indicating the longest time for completing transmission of the file to be transmitted; the characteristic information is used for identifying and/or detecting the data packets in the file to be transmitted.

It may be appreciated that the QoS parameter corresponding to the first transmission file and/or the filter having an association relationship with the first transmission file may be determined by the first network element and transmitted to the current communication device by the first network element.

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

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

Optionally, after obtaining the filter and/or QoS parameter, the first network element (e.g., PCF) may forward, to the communication device, the filter and/or QoS parameter corresponding to the pending file through a third network element (e.g., SMF). In this way, after receiving the filter and/or QoS parameter corresponding to the file to be transmitted, the communication device may identify the data packet corresponding to the first sending file from the data packets of the first data by using the filter, and transmit the data packet of the first sending file through the first QoS flow matched with the QoS parameter, thereby meeting the service quality requirement of the first sending file.

Fig. 9 is a second flowchart of a data transmission method according to an embodiment of the present application, as shown in fig. 9, where the method includes the following matters.

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

Step 920, the communication device transmits the third data through a transmission path; wherein, the data packets belonging to different transmission files in the third data 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. 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 the embodiment of the present application, the first data may be application layer data.

In the embodiment of the present application, the transmission file may be a complete file, that is, a completion file in a conventional sense, for example, a video file, an image file, etc. The transmission file may be a part of a file, for example, a file corresponding to an I frame/B frame/P frame. The transmission file may also be other forms of data, which the embodiments of the present application do not limit.

Alternatively, the transmission file may be a file transmitted unidirectionally (e.g., transmitted upstream, or transmitted downstream). In the embodiment of the present application, the transmission file may be the first sub-file or the second sub-file in the pending file mentioned in the above embodiment.

It should be noted that different transmission files may have different data/content types. That is, different transmission files correspond to different data/content types. For example, the first data may include three transmission files, I-frame, B-frame, and P-frame corresponding files, respectively.

It should be appreciated that the QoS parameters corresponding to different transmission files may be different. For example, higher transmission rates may be required for higher latency requirements for the transmitted file; while higher transmission rates may not be required for transmitted files with lower latency requirements. Based on this, the communication device can identify the transmission file (which may also be understood as a file type) to which each data packet in the first data belongs, thereby providing different services for different transmission files (file types).

In the embodiment of the application, the communication device can identify each data packet in the first data by taking the data packet as a unit, determine the transmission file to which each data packet belongs, and obtain the label information corresponding to each data packet.

Optionally, in step 910, the communication device may specifically perform filtering processing on the data packets in the first data through multiple filters, to determine tag information corresponding to each data packet. And indicating the transmission file to which the current data packet belongs through the tag information.

It will be appreciated that the filter is used by the communication device to identify packets of different transmitted files from the application layer data (e.g., the first data described above). Wherein, a plurality of filters have association relation with a plurality of transmission files.

Alternatively, there may be a one-to-one correspondence between filters and sendfiles, i.e., one filter for each sendfile. That is, a transmission file can be obtained by filtering through a filter.

Optionally, the communication device may utilize an existing packet detection and/or data flow binding mechanism to identify and filter the first data, and determine a transmission file to which each packet in the first data belongs. The communication device may further introduce a new protocol layer, for example, the adaptation layer (or called an adaptation unit) performs identification and filtering processing on the first data, determines a transmission file to which each data packet in the first data belongs, and obtains tag information corresponding to the data packet.

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

Exemplary, reference is made to the communication device protocol layer architecture schematic shown in fig. 7. On the terminal device side, the adaptation layer may 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 application, after determining the transmission file to which each data packet belongs, the communication device may add tag information to each data packet in the first data, and tag the transmission file to which each data packet belongs by using the tag information, thereby obtaining third data. That is, each data packet in the third data has a tag information, which is specifically used to indicate the transmission file to which the current data packet belongs. For example, the tag information may be identification information of a transmission file to which the current 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, qoS parameters corresponding to the data packets belonging to different transmission files in the third data are different (even if the data packets in the third data are all transmitted through one transmission path), so as to ensure QoS requirements of different transmission files.

Alternatively, the transmission path may be any transmission link capable of transmitting IP packets, ethernet packets, and Unstructured packets, such as QoS flows, radio bearers, PDU sessions, or PDN connections, which is not limited in this embodiment of the present application.

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

Correspondingly, after receiving the third data sent by the terminal device, the UPF adaptation layer may perform merging/reordering processing and label removing processing on the data packet in the third data based on the label information corresponding to each data packet in the third data, and transmit the processed data to a next node (such as an application server) of the UPF.

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

And the communication equipment performs merging processing and/or reordering processing on the data packets in the fourth data based on the label information of each data packet in the fourth data to obtain second data.

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

Alternatively, the communication device may perform the merging and/or reordering of the fourth data using the adaptation layer, and transmit the processed data to a next node of the communication device, or an application layer of the communication device.

Therefore, in the data transmission method provided by the embodiment of the application, the communication device can add the tag information for each data packet in the first data to obtain the third data, and further bind the third data to a transmission path for transmission, and the QoS parameters corresponding to the data packets of different transmission files in the third data are different, so as to meet the service quality requirements of different transmission files.

Optionally, qoS parameters corresponding to the first transmission file and/or a filter having an association relationship with the first transmission file is determined based on the request message; the request message is used for requesting to transmit the file to be transmitted based on the demand information; the first sending file may be a first sub-file or a second sub-file in the file to be transmitted; the requirement information comprises at least one item of file size information, time requirement information and characteristic information of the file to be transmitted; the time requirement information is used for indicating the longest time for completing transmission of the file to be transmitted; the characteristic information is used for identifying and/or detecting the data packets in the file to be transmitted.

Here, the QoS parameter corresponding to the first transmission file and/or the filter having the association relationship with the first transmission file is determined by the first network element and is sent to the communication device.

Specifically, the first network element may receive the request message and determine a filter and/or QoS parameter of the pending file based on at least one of file size information, time requirement information, and feature information of the pending file included in the request message.

It should be noted that, the process of determining the filter and/or QoS parameter corresponding to the file to be transmitted based on the request message is the same as that of the above embodiment, and is not repeated herein for brevity.

Further, the first network element (e.g., PCF) may forward the filter and/or QoS parameters of the pending file to the communication device via a third network element (e.g., SMF). In this way, after receiving the filter and/or QoS parameter corresponding to the file to be transmitted, the communication device may determine and mark the transmission file to which each data packet in the first data belongs by using the filter, and bind the marked data to a transmission path for transmission. And, for the data packet belonging to different sending files in the transmission course, set up different QoS parameter.

For example, "downstream signal" means that the transmission direction of the signal is the first direction.
