The embodiments described below by referring to the figures are exemplary only for explaining the present disclosure and should not be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents coming within the spirit and scope of the appended claims.

This disclosure proposes a data transmission method, device, terminal, storage medium, and computer program product, which can configure appropriate discarding timings for business data of different types of business information, and transmit business data based on the adjusted target discarding timing time It can effectively improve the efficiency and stability of business data transmission, and enhance the timeliness and reliability of business data transmission.

FIG. 1 is a schematic flowchart of a data transmission method proposed by an embodiment of the present disclosure.

Wherein, it should be noted that the execution subject of the data transmission method in the embodiment of the present disclosure is a data transmission device, and the device may be implemented by software and/or hardware.

As shown in FIG. 1, the data transmission method includes step S101 to step S104.

S101: Obtain service data to be transmitted.

Wherein, the service-related data to be transmitted by the terminal may be referred to as service data to be transmitted, and the service data may be, for example, call data, voice data, video stream data, etc. to be transmitted by the terminal that support corresponding communication protocols.

Wherein, when the terminal is to transmit the corresponding service data, the service data can be encapsulated into data packets for transmission in the wireless interface, and the wireless interface can include a data link layer, and the data link layer supports the packet data convergence protocol PDCP.

Therefore, the data transmission method in the embodiment of the present disclosure may be a data transmission method based on the Packet Data Convergence Protocol PDCP. When transmitting service data, the data format of the service data may specifically be Radio Resource Control (Radio Resource Control, RRC) message, or it can also be an Internet Protocol (Internet Protocol IP) packet on the user plane, or it can also be any other possible data format.

In the embodiment of the present disclosure, obtaining the service data to be transmitted may be obtained from the radio resource management (Radio Resource Control, RRC) layer RRC message and/or IP packet as service data, or may also be obtained from the service data adaptation protocol layer (Service Data Adaption Protocol, SDAP) to obtain the data packets to be transmitted as business data.

S102: Determine service type information corresponding to the service data.

Wherein, the type information used to describe the service quality requirements of the service data may be referred to as service type information, and the service type information may specifically be, for example, high real-time type, high reliability type, both real-time and reliable type, and the like.

Among them, the business data can be classified in advance according to the response time, loss, signal-to-noise ratio, reliability requirements, etc. required for the transmission of business data, and a variety of optional business type information can be obtained, and then in the process of actually transmitting business data , to determine the service type information corresponding to the service data to be transmitted.

For example, you can refer to the requirements for transmitting business data in actual data transmission scenarios, and divide the business data rows to obtain high-real-time business data, high-reliability business data, and both real-time and reliable business data. Correspondingly, The high-real-time type, high-reliability type, and real-time and reliable type obtained by dividing can be used as optional business type information. When the business data is data in business scenarios with high real-time requirements such as online games, the business The type information may be of a high real-time type, or, when the business data is a business scenario requiring high stability such as web page browsing and form data submission, the business type information may be of a high reliability type.

In the embodiments of the present disclosure, the business type information corresponding to the business data in various business scenarios can be obtained according to actual needs, and the business type information corresponding to the business data can be marked during the business data transmission process, so that when the business to be transmitted is received When processing data, directly parse the marked content of the business data to determine the business type information corresponding to the business data, or it can also integrate the data of the same business type information into Stateful Data Plane Abstraction (SDPA) data package, add the corresponding service type information in the data package, and determine the data package to which the service data belongs when receiving the service data to be transmitted, so as to determine the service type information corresponding to the service data, or use network slicing , according to the network transmission characteristics of different service data, determine the service type information corresponding to the service data.

In the embodiment of the present disclosure, network slicing can be used as a way to determine service type information, as shown in FIG. 2 , which is a schematic diagram of a network slicing model proposed in an embodiment of the present disclosure. In the terminal, the network slicing technology uses the application identifier ( Traffic Descriptors such as Application Identification (APPID), IP 3-tuple, Fully Qualified Domain Name (FQDN), Data Network Name (Data Network Name, DNN), Connection Capability, etc. Data is mapped to Quality of Service (QoS) data streams, and corresponding QoS data stream identifiers are added to different QoS data streams at the SDAP layer, and submitted to the terminal routing policy file, which is connected to the cloud network through the access network. Further, the service type information corresponding to the service data is determined.

S103: Determine the target discard timing time matching the service type information.

Wherein, the discarding timing time corresponding to the service type information of the service data may be called the target discarding timing time, and the target discarding timing time may be the longest transmission waiting time used to indicate that the terminal is transmitting the service data.

In the embodiment of the present disclosure, the timing time of the timer can be set to mark the target discarding timing time, and the timer can be used to mark the longest waiting time for sending service data in the terminal, that is to say, when the terminal When the service data to be transmitted is received, the timer may be triggered to count, and when the timer expires and the service data is not transmitted, the step of discarding the service data may be performed.

In the embodiment of the present disclosure, the target discard timing corresponding to various service types can be preset, and the target discard timing can be matched and saved with the corresponding service type information. When the service type information of the service data is determined, select the Type information matches the target discard timing, and configure the target discard timing as the timing of the timer, or use the timing calculation rules to calculate the timing that matches the service type information as the target discard timing, Alternatively, any other possible manner may be used to determine the timing time that matches the service type information as the target discarding timing time.

S104: Transmit service data according to the target discard timing.

In the embodiment of the present disclosure, multiple corresponding transmission strategies may be set according to the target discarding timing, and the transmission strategy corresponding to the service data may be determined according to the longest transmission waiting time corresponding to the service data.

In some embodiments, when transmitting service data according to the target discarding timing, if the target discarding timing has not timed out, the service data is transmitted in response to the data transmission instruction, and if the target discarding timing is timed out, the service data is discarded. Business data, because the business data that has not been transmitted over time is discarded, it can prevent transitional delay and queuing phenomenon, realize the orderly and stable transmission of business data of different business types, and improve the flexibility of business data transmission control sex and transmission effects.

In the embodiments of the present disclosure, when transmitting service data according to the target discarding timing time, the timer may be triggered to start when the service data is received, and the timer may be configured as the target discarding timing time, and when the target discarding timing time exceeds From time to time, the business data can be triggered to be discarded, and when the target discarding time has not expired, the business data can be transmitted according to the data transmission instruction, so as to realize the timely transmission control of the business data, and can effectively take into account the transmission effect and transmission of the business data. The personalized transmission quality requirements required by the business data can effectively improve the control effect of business data transmission.

In the embodiments of the present disclosure, the target discard timings corresponding to different service type information may be the same or different.

For example, game, augmented reality (Augmented Reality, AR)/virtual reality (Virtual Reality, VR), voice and other service data are expected to be transmitted as fast as possible at the user level. If the transmission of service data exceeds a certain time limit, it may The meaning of transmission will be reduced due to timeout. For example, business data with high reliability requirements but relatively low real-time requirements, such as web browsing, form data submission, etc., at the user level, business data is expected to be the most reliable (reliable) Correspondingly, this type of business data has relatively low real-time requirements.

Therefore, in the embodiments of the present disclosure, different target discarding timings can be set for different service types of information. When it is detected that the target discarding timing has not expired, the data transmission instruction can be monitored, and the service data can be transmitted when the data transmission instruction is detected. When it is detected that the target discarding timeout expires, the service data may be discarded to process subsequent services.

The data transmission method proposed in the embodiments of the present disclosure obtains the service data to be transmitted, determines the service type information corresponding to the service data, determines the target discarding timing time matching the service type information, and transmits the business according to the target discarding timing time Data, because it is to determine the service type information, configure the target discard timing time that matches the service type information, and can configure the appropriate discard timing time for business data of different service type information, when the transmission service is based on the adjusted target discard timing time It can effectively improve the efficiency and stability of business data transmission, and enhance the timeliness and reliability of business data transmission.

In the fifth generation mobile communication technology wireless access network (5th Generation Mobile Communication Technology-Radio Access Network, The QoS architecture in 5G-RAN) is connected to the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) core network. The 5G core network establishes one or more protocol data unit sessions for each terminal. 5G-RAN and protocol The data unit session establishes at least one user plane data radio bearer together, and the additional user plane data radio bearer of the QoS flow of the protocol data unit session can be configured for each terminal, and the 5G-RAN maps the service data belonging to different protocol data unit sessions to In different user plane data radio bearers, the service type information in the terminal and 5G core network is associated with the QoS flow, the level mapping between the terminal and 5G-RAN, and the uplink and downlink QoS flows are associated with the user plane data radio bearer.

In the embodiment of the present disclosure, as shown in Figure 5, which is a flow chart of service data transmission proposed by another embodiment of the present disclosure, the QoS flow identifier is added to the service data in the session of the protocol unit, and the service at the SDAP layer In the data/protocol data unit session, judge whether the service data corresponds to the quality of service QoS flow identifier, and according to the judgment result, input multiple service data into multiple data bearers in the corresponding protocol data unit session, and classify them into different The business data of the packet data convergence protocol PDCP, in the confirmed mode, transmits the business data from the uplink physical shared channel to the multi-codeword transmission channel, and then transmits it to the dedicated traffic channel; in the unacknowledged mode, the business data is divided into uplink wireless Link control protocol service data and downlink radio link control protocol service data are transmitted to the single codeword transmission channel through the dedicated service channel, and then transmitted to the radio frequency layer through the downlink physical shared channel.

S303: If there is no QoS flow identifier corresponding to the service data, determine the current running content in the terminal, and determine the service type information corresponding to the service data according to the current running content.

Wherein, the terminal may be a mobile phone, a wearable device, etc. used by the user.

Wherein, in the application scenario, the relevant content currently running on the terminal may be referred to as the current running content, and the current running content may be related content such as an application program, a small program, or a web page currently running on the terminal.

In the embodiment of the present disclosure, the service data may be generated by the terminal. When the service data does not correspond to the service quality QoS flow identifier, the service type information corresponding to the service data may be determined according to the current operation content by identifying the current operation content in the terminal, or , the service requirement information corresponding to the current operation content may also be identified, and the service type information corresponding to the service data may be determined according to the service requirement information.

For example, when the terminal is running an online game, it is determined based on the current running content that it has a high demand for real-time performance, then high real-time business type information can be selected as the business type information of the business data involved in the game program.

In the embodiment of the present disclosure, the service type information can be determined according to the current running content of the terminal, and various identifiers corresponding to the service type information can be preset, and the identifiers can be added to the corresponding current running content, thus, in the current running content Identify the corresponding identifier in the corresponding identifier, determine the service type information corresponding to the corresponding identifier, and use it as the service type information corresponding to the service data, or use any other possible way to realize the determination of the service corresponding to the service data according to the current operation content type information.

In some embodiments, in the embodiments of the present disclosure, when determining the service type information corresponding to the service data according to the current running content, if the current running content is content with high real-time requirements, then determine the business type information as the high real-time type, If the current operation content is content with high reliability requirements, determine the business type information as a high reliability type. Since the current operation content needs to be analyzed, it is judged whether the current operation content needs high real-time requirements or high reliability. Based on the requirements of the current running content, it is divided into high real-time type or high reliability type, and used as business type information, so that the determined business type information can effectively represent the demand of the current running content, so as to effectively Guarantee the accuracy of the representation of business type information on the needs of current operating content, and effectively improve the convenience and efficiency of determining business type information of business data while effectively satisfying the determination accuracy of personalized business type information.

Among them, the current running content with relatively high real-time requirements and relatively low delay requirements can be called content with high real-time requirements. Content with high real-time requirements can be, for example, games, voice calls, video calls, etc. content.

Among them, the current running content with relatively high reliability requirements may be referred to as content with high reliability requirements, and the content with high reliability requirements may be, for example, content such as text transmission and web page display.

In the embodiment of the present disclosure, the corresponding real-time and reliability identifiers can be set in the current running content of the terminal, and the current running content can be judged as content with high real-time requirements or high reliability requirements according to the identifiers, or it can also be Identify the transmission scene of the current running content. For example, when the transmission scene is a game scene, the current running content is content with high real-time requirements; when the transmission scene is web browsing scene, the current running content is content with high reliability requirements.

S304: Determine the target discard timing time matching the service type information.

In some embodiments, the corresponding matching algorithm or matching rule can be referred to to determine the target discarding timing that matches the service type information, or it can also be combined with a pre-trained matching model to determine the target discarding time that matches the service type information. Timing.

In the embodiment of the present disclosure, the identification code of the corresponding target discard timing time can be added to the service quality QoS flow identifier in advance. The identification code can be a combination of codes, numbers, symbols, etc., and is used to identify the corresponding discard timing time. Through the identification code, identify the corresponding discarding timing time as the target discarding timing time, or, any other possible manner may be used to determine the discarding timing time corresponding to the quality of service QoS flow identifier.

For example, when the service data corresponding to the packet data convergence protocol PDCP is transmitted to the PDCP layer, the quality of service QoS flow identifier can be identified, and the corresponding discard timing time can be determined according to the set corresponding relationship, and the corresponding discard timing time The target discard timing is used to control the transmission of service data, or the QoS flow identifier of the service data can be queried in the terminal, and the corresponding discard timing is dynamically configured according to the QoS flow identifier.

In some embodiments, if the service type information is a high real-time type, the first discarding timing is used as the target discarding timing, wherein the first discarding timing is less than the first timing threshold; or if the service type information is high reliability type, then use the second discarding timing as the target discarding timing, wherein the second discarding timing is greater than the second timing threshold, and the first timing threshold is less than or equal to the second timing threshold, because the service type information After detailed analysis, when the service type information is high real-time type, you can configure the first discard timing time, and when the service type information is high real-time type, you can configure the second discard timing time at this time, which can realize the personalization of the discard timing time Configured so that the configured discarding timing is effectively adapted to different business transmission requirements of business data, and, since the first discarding timing is smaller than the first timing threshold, the second discarding timing is greater than the second timing threshold, and The first timing threshold is less than or equal to the second timing threshold, so that the transmission control of service data can effectively take into account the real-time requirements and stability requirements of transmission, and effectively guarantee the overall transmission control effect.

In the embodiments of the present disclosure, the time threshold corresponding to the first discarding timing may be referred to as the first timing threshold, and the first timing threshold may be used to measure the size of the configured first discarding timing. When configuring When the first discard timing time is less than the first timing threshold, it can indicate that the discard timing time has been shortened accordingly, that is, the service type information is a high real-time type, indicating that the real-time requirements of service data are high. The relatively small first discarding timing enables timely transmission of service data and guarantees the real-time requirements of service data transmission.

For example, the first discarding timing may be configured as 30ms.

In the embodiment of the present disclosure, the time threshold corresponding to the second discard timing time may be referred to as the second timing time threshold, and the second timing time threshold may be used to measure the size of the configured second discard timing time. When configuring When the second discarding timing is greater than the second timing threshold, it can indicate that the discarding timing has been extended correspondingly, that is, the service type information is a high-reliability type, indicating that the reliability of the service data is high. The long second discard timing enables stable transmission of service data and ensures the stability requirements of service data transmission.

For example, the second discarding timing may be configured as 3s, or no upper limit may be set.

When based on the adjusted target discard When the business data is transmitted at regular time, it can effectively improve the efficiency and stability of business data transmission, and enhance the timeliness and reliability of business data transmission. If there is a quality of service QoS flow identifier corresponding to the service data, then using the quality of service QoS flow identifier as the service type information and using the service quality QoS flow identifier as the service type information can effectively improve the efficiency of determining the service type information, and, because The quality of service QoS can represent the transmission quality requirements of business data accordingly, so that when the quality of service QoS flow identifier is used as the service type information, it can effectively guarantee the accuracy of service type information on the transmission quality requirements of service data and improve data transmission. Control accuracy and transmission control effect. If there is no service quality QoS flow identification corresponding to the business data, then determine the current running content in the terminal, and determine the service type information corresponding to the business data according to the current running content, and can refer to the current running content in the terminal for unidentified services The service data identified by the quality QoS flow identifies the corresponding service type information, which effectively improves the comprehensiveness, accuracy, and flexibility of the service type information determination, thereby effectively improving the accuracy of the target discard timing time setting, and effectively taking into account the timely transmission of service data sex and stability. Due to the requirement analysis for the current operation content, it is judged whether the requirement of the current operation content is high real-time requirement or high reliability requirement, and based on the requirement of the current operation content, it is divided into high real-time type or high reliability type, and As business type information, the determined business type information can effectively represent the requirements of the current operating content, thereby effectively ensuring the accuracy of the representation of the business type information on the current operating content requirements, and effectively satisfying the personalized business type information. While determining the accuracy, it effectively improves the convenience and efficiency of determining the business type information of the business data.

To sum up, as shown in Figure 6, Figure 6 is a flow chart of data transmission proposed by another embodiment of the present disclosure. The terminal has corresponding current running content, and when the terminal has service data to send, it is judged whether the service data corresponds to Quality of service QoS flow identification, if so, then identify the corresponding quality of service QoS flow identification, adopt the corresponding discarding timing according to the quality of service QoS flow identification; Time is used as the target discard timing time; for QoS flow identifiers with high stability requirements, a higher discard timing time is used as the target discard timing time, and when the target discard timing time exceeds, the service data is discarded.
