[0058] With the rapid development of technology, the demand for computing services in technical fields such as autonomous driving and artificial intelligence has shown an explosive growth trend. Since the network has real-time communication perception capabilities and powerful computing resources and can provide efficient computing services, communication-computing integration technologies such as cloud-network integration and computing power network have been effectively developed. Among them, the core idea of cloud-network integration is to integrate cloud computing and the network together to provide more powerful computing resources and more efficient network transmission capabilities; the computing power network is to thoroughly integrate computing power resources and computing power scheduling into the communication network to provide computing services that better meet user needs in a more overall and convenient way. In a wireless network, computing tasks are usually offloaded to the edge cloud for completion, and the QoS of computing tasks usually includes two parts: communication QoS and computing QoS. However, there is uncertainty in the air interface, and it is difficult to provide computing services with QoS guarantees for air interface changes at the present stage.

[0059] The following further describes the present application in detail with reference to the accompanying drawings and embodiments.

[0060] In actual applications, the computing tasks of each user correspond to different QoS requirements. For example, the computing tasks involved in road real-time monitoring and the computing tasks involved in image generation based on chatGPT correspond to different QoS requirements. Specifically, the computing tasks involved in road real-time monitoring need to transmit large amounts of picture data for image recognition. Usually, only the computing resources of the central processing unit (CPU, Central Processing Unit) are utilized, and the discrimination result is output through a classification algorithm, with relatively high requirements for latency and computing accuracy; the computing tasks involved in image generation based on chatGPT need to transmit small amounts of text data. Usually, a large amount of CPU and graphics processing unit (GPU, Graphics Processing Unit) computing resources are required, and the image result is output through chatGPT, with relatively low requirements for latency and computing accuracy. It can be seen from this:

[0061] 1. The computing QoS requirements of different computing tasks are different, specifically including: the computing resources required by different computing tasks and the requirements for latency and accuracy are different, and different configurations need to be made for computing tasks according to different computing QoS requirements. For example, real-time tasks require a real-time operating system to ensure latency requirements, and non-real-time tasks can use a batch processing operating system to improve the average processing latency.

[0062] 2. There is no binding relationship between the communication QoS requirements (such as latency, bit error rate) and the computing QoS requirements (such as latency, accuracy) of computing tasks.

[0063] 3. The overall QoS of computing tasks will be affected by communication QoS and computing QoS. For example, the total latency of computing tasks includes transmission latency and computing latency.

[0064] Based on this, in each embodiment of the present application, a wireless network node obtains a data packet of a first computing task sent by a terminal. The data packet is configured with a CTAP header, and the CTAP header at least includes the terminal ID of the terminal, the task ID of the first computing task in the terminal, and the computing QoS ID of the first computing task; the first computing task is uniquely identified by the above terminal ID and task ID; the wireless network node maps the first computing task to a computing bearer matching the computing QoS ID based on the data packet, and generates an operating system control block corresponding to the first computing task based on the CTAP header. In this way, the wireless network node executes the first computing task on the computing bearer according to the generated operating system control block. In the above solution, by introducing a computing bearer and allocating a computing bearer for a computing task based on the computing QoS requirement of the computing task, it is ensured that the computing tasks executed on the same computing bearer all have the same computing QoS requirement, thereby enabling better realization of the reasonable scheduling of computing tasks and ensuring the computing QoS of computing tasks.

[0065] First, in terms of the system architecture, in the embodiments of the present application, a computing bearer for a wireless network oriented to computing task QoS guarantee is introduced, and computing is regarded as a part of the base station capabilities. On this basis, through the integration with the wireless architecture, a wireless network QoS architecture for communication-computing integration is proposed to achieve the organic integration of computing, interaction processes, and wireless communication, and to realize the guarantee of computing task QoS in a dynamic wireless environment.

[0066] Specifically, the wireless network QoS architecture for communication-computing integration is as Figure 1 shown. First, in terms of communication functions, a wireless network node (RAN Node) can be connected to multiple terminals, where the wireless network node can be a base station. Taking the communication protocol design of the fifth-generation mobile communication technology (5G) network as an example, there is one and only one protocol data unit (PDU, Protocol Data Unit) session (Session) between each terminal and the wireless network node, and multiple radio bearers (Radio Bearers) belonging to the same terminal can be established in each PDU session to carry the transmission of different QoS flows. In terms of computing functions, multiple computing bearers (CB, Computing Bearer) can be established in a wireless network node, and each computing bearer can carry the execution of computing tasks (QoCS Task) of different terminals.

[0067] Based on Figure 1 the architecture shown, the functions of the terminal side and the wireless network node side are introduced respectively below.

[0068] The terminal side (UE) includes the following functions:

[0069] 1. Transmitting CTAP (TS CTAP) entity: After receiving the communication QoS requirements and computing QoS requirements of the computing task, it configures the computing QoS requirements for each computing task. The configuration method is to attach a CTAP header to the data packet of the computing task. The CTAP header includes the following information corresponding to the computing task: user ID, task ID, timestamp, priority, and computing QoS ID.

[0070] In the CTAP header, the user ID is the unique identifier of the terminal connected to the wireless network node; the task ID is the unique identifier of the computing task in the terminal. Therefore, based on the user ID and task ID in the CTAP header, a unique computing task can be determined. The computing QoS ID can be an identifier or a value, corresponding to different computing QoS requirements. The computing QoS requirements at least include: task type, such as latency-sensitive, CPU-intensive, I / O-intensive, batch type, etc.; total latency of the computing task; resource requirements, such as memory requirements, CPU / GPU / Field Programmable Gate Array (FPGA) requirements, etc.

[0071] 2. Task TFT (Task TFT) entity: It determines the computing task according to the user ID and task ID in the CTAP header, and adds QoS flow information, such as Quality of Service Flow Identifier (QFI), to the computing task according to the communication QoS requirements of the computing task obtained by transmitting CTAP, and maps the data packet of the computing task to the corresponding QoS flow.

[0072] For example, in a 5G network, the TFT maps the data packet to the QoS flow according to the Internet Protocol (IP) header of the data packet.

[0073] 3. Communication protocol stack: It is used to establish PDU sessions and radio bearers, and map the QoS flow to which the data packet of the computing task belongs to different radio bearers according to the QoS flow information. The communication protocol that can be adopted is consistent with the protocol adopted on the wireless network node side, including but not limited to Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), Media Access Control (MAC), physical layer protocol, etc.

[0074] The wireless network node side (RAN NODE) includes the following functions:

[0075] 1. Receiving CTAP (RC CTAP, Receiving CTAP) entity: After receiving the computing task data packet with a CTAP header, map the computing task to different computing bearers according to the computing QoS ID in the CTAP header. In particular, the dynamic change of the wireless air interface will change the transmission time. Therefore, the receiving CTAP will calculate the transmission delay according to the timestamp in the CTAP header and the current system time, and subtract the calculated transmission delay from the total time of the computing task in the computing QoS requirements of the computing task to obtain the computing task execution time, so as to ensure the QoS of the computing task in the case of wireless environment changes. After that, after the receiving CTAP entity modifies the total delay of the computing task in the computing QoS requirements to the above-mentioned computing task execution time, it fills in the operating system control block together with the user ID, task ID and priority, such as the job control block of the batch operating system, as the basis for job management and scheduling. Finally, remove the CTAP header.

[0076] 2. Task TFT entity: Filter the QoS Flow into the data packets of the original computing tasks.

[0077] 3. Computing bearer: Here, the computing bearer is the general term for the wireless network node to allocate different computing-related entities and configurations for the user, such as Figure 2As shown in the figure. The computing load includes at least job control and scheduling (M&S, Management & Scheduling) and thread M&S. Job M&S can create jobs and process jobs in real time, batch jobs, etc., and schedule computing tasks according to the operating system control block generated by the received CTAP entity. For example, scheduling algorithms such as preemption, first-come, first-served, shortest job first, priority first, and highest response ratio first are used for scheduling. For each job, thread M&S will create threads. Among them, in a batch operating system, processes will be created first after the job, and then corresponding scheduling policies, such as preemptive, time slice, etc., will be configured for scheduling.

[0078] 4. Communication protocol stack: The communication protocols that can be adopted are the same as those adopted by the user side, including but not limited to SDAP, PDCP, RLC, MAC, physical layer protocols, etc.

[0079] Based on Figure 1 the system architecture shown in Figure 2 and the composition of the computing load shown in Figure 3 the interaction process between the wireless network node and the terminal in the data transmission method of the embodiment of the present application is shown. Combining Figure 3 :

[0080] 1. The transmitting CTAP entity of the terminal adds a CTAP header to the data packet of the computing task according to the computing QoS requirements of the computing task (QoCS Task), and then sends the data packet of the computing task with the CTAP header added (Task Packet) to the task TFT entity.

[0081] 2. The task TFT entity determines the first computing task according to the CTAP header, maps the data packet of the first computing task to the QoS flow that matches the communication QoS requirements of the first computing task, and sends it to the transmitting SDAP entity.

[0082] 3. The transmitting SDAP entity maps the QoS flow to the corresponding data radio bearer (DRB) according to the QFI (Mapping of QoS flow to a DRB). For the data packet with the SDAP header configured (SDAP header is configured), after adding the SDAP header to the data packet (Adding SDAP header), the transmitting SDAP entity sends the data packet to the receiving SDAP entity on the radio network node side. For the data packet without the SDAP header configured (SDAP header is not configured), the transmitting SDAP entity directly sends the data packet to the receiving SDAP entity on the radio network node side.

[0083] 4. The receiving SDAP entity of the radio network side node (Receiving SDAP entity) resolves the QoS flow (Reflective QoS flow to DRB mapping), removes the SDAP packet header from the resolved QoS flow (Removing SDAP header), and sends it to the task TFT entity on the radio network node side.

[0084] 5. The task TFT entity restores the received QoS flow mapping to the data packet of the computing task and sends it to the receiving CTAP entity (Receiving CTAP entity).

[0085] 6. The receiving CTAP entity maps the first computing task to different computing bearers and fills in the operating system control block according to the computing QoS ID in the CTAP packet header of the data packet of the computing task (Mapping of Task Packet to a CB and fill OSCB), and then removes the CTAP packet header (Removing CTAP header).

[0086] 7. The computing bearer completes the computing execution of the first computing task according to the operating system control block filled in by CTAP.

[0087] Combined with Figure 4 It can be seen that in the embodiment of the present application, on the basis of the communication protocol in the related technology, a CTAP packet header is added to the data packet.

[0088] Combined with the above interaction process, next, the embodiment of the present application will be described with the radio network node and the terminal as the execution entities respectively. In the following embodiments, the data transmission method corresponding to each execution entity can be understood in combination with the execution actions of the corresponding execution entity in the above interaction process, and will not be elaborated below.

[0089] An embodiment of the present application provides a data transmission method, which is applied to a wireless network node, such as Figure 5 shown. The method includes:

[0092] Step 502: Map the first computing task to a computing bearer that matches the computing QoS ID, and generate an operating system control block corresponding to the first computing task based on the CTAP header.

[0093] Step 503: Execute the first computing task on the computing bearer according to the operating system control block.

[0094] Wherein, in one embodiment, the obtaining the data packet of the first computing task sent by the terminal includes:

[0095] Receive a QoS flow sent by the terminal; the data packet is mapped in the QoS flow, and the QoS flow matches the communication QoS of the first computing task;

[0097] In one embodiment, after mapping the first computing task to a computing bearer that matches the computing QoS ID, the method further includes:

[0098] Remove the CTAP header from the data packet.

[0099] In one embodiment, the CTAP header further includes the priority of the first computing task.

[0101] When generating the operating system control block corresponding to the first computing task based on the CTAP header, determine the execution time of the first computing task based on the timestamp, the system time of the wireless network node, and the total delay of the first computing task, and write the execution time of the first computing task into the operating system control block.

[0102] In one embodiment, the QoS ID included in the CTAP header represents at least one of the following:

[0103] The task type of the first computing task;

[0104] The total delay of the first computing task;

[0105] The resource requirements of the first computing task.

[0106] An embodiment of the present application provides a data transmission method, which is applied to a terminal. As Figure 6 shown, the method includes:

[0107] Step 601: Add a CTAP header to the data packet of the first computing task.

[0108] Wherein, the CTAP header at least includes the terminal ID of the terminal, the task ID of the first computing task in the terminal, and the computing QoS ID of the first computing task; the terminal ID and the task ID are used to uniquely identify the first computing task;

[0116] In the above embodiments, by introducing a computing bearer into the system architecture and allocating a computing bearer for a computing task based on the computing QoS requirements of the computing task, such that the computing tasks executed by the same computing bearer all have the same computing QoS requirements. Thus, it is possible to better achieve the reasonable scheduling of computing tasks and ensure the computing QoS of computing tasks. In addition, since the computing tasks with the same computing QoS requirements are placed on the same computing bearer for execution, the guarantee of communication QoS is decoupled from the guarantee of computing QoS, and the number of radio bearers and computing bearers can be correspondingly reduced, saving network resources. Moreover, by calculating the transmission delay according to the timestamp in the CTAP header and the current system time, and subtracting the calculated transmission delay from the total computing task time in the computing QoS requirements of the computing task to obtain the computing task execution time, the QoS of the computing task is ensured in the case of changes in the wireless environment.
