[0042] As vertical industries' demand for communications continues to increase, 5G networks need to improve their service assurance capabilities. Against this backdrop, the TSN Ethernet protocol has become an important technology for solving time-sensitive scenarios through time synchronization, data scheduling, and system configuration. Figure 1 The system architecture of TSN combined with 5G in the related technology is shown, in which time synchronization and Ethernet protocol functions are achieved by adding a TSN converter, namely the network side TSN converter (NW-TT, Network TSN Translator) in the UPF network element. Figure 1 Under the system architecture, the UPF network element schedules TSN services based on different priorities, providing transmission-level guarantees for TSN services. Due to the high cost and complex operation and maintenance of UPF network elements, they are difficult to deploy in 5G networks. Therefore, when scheduling TSN services, base stations need to connect to the UPF network element located in the core network. In addition, in time-sensitive environments, the transmission delay of data packets passing through the UPF network element will increase, resulting in increased latency for TSN services.

[0043] Based on this, the service scheduling method, device, base station and storage medium provided in the embodiments of the present application are configured such that the base station receives TSN service data corresponding to each first terminal in at least one first terminal sent by the edge computing node, wherein the TSN service data corresponding to each first terminal has a first priority, and the first priority represents the priority of the corresponding TSN service parsed based on the Ethernet protocol. The first base station performs TSN service scheduling for the at least one first terminal based on the system clock and the first priority corresponding to the TSN service. That is to say, in the embodiments of the present application, the first base station implements the function of the TSN converter, thereby sinking the deployment of the TSN converter from the UPF network element to the base station, reducing the latency of the TSN service.

[0044] The present application is described in further detail below with reference to the accompanying drawings and embodiments.

[0045] Figure 2 The system architecture of TSN combined with 5G provided by the embodiment of the present application is shown. Figure 1 The NW-TT function has been integrated into the 5G base station (gNB) instead of the UPF network element, performing Ethernet-IP protocol conversion. This allows TSN services flowing through the 5G system to be synchronized with the TSN system clock, leveraging the 5G system's precise timing. Furthermore, a local scheduling module has been added to the gNB to collect TSN service priorities and implement unified queue management for packets requiring transmission, enabling early transmission of high-priority packets.

[0046] based on Figure 2 The system architecture shown in FIG. 1 is a diagram illustrating a service scheduling method applied to a first base station. Figure 3 As shown, the method includes:

[0047] Step 301: Receive TSN service data corresponding to each first terminal in at least one first terminal sent by an edge computing node.

[0048] The TSN service data corresponding to each first terminal has a first priority; the first priority represents the priority of the corresponding TSN service parsed based on the Ethernet protocol.

[0049] Here, the edge computing node is a business platform built on the edge of the network close to the terminal side, which can provide storage, computing, network and other resources to reduce the bandwidth and delay loss caused by network transmission and multi-level forwarding. In an embodiment of the present application, the edge computing node receives a TSN service request from the terminal, uses a deep parsing method to perform TSN service identification on the TSN service request, obtains TSN service data related to the TSN service request, and parses the first priority of the corresponding TSN service based on the Ethernet protocol. Afterwards, the edge computing node encapsulates the TSN service data and sends the encapsulated data packet to the first base station, wherein the encapsulated data packet carries the first priority of the corresponding TSN service.

[0050] In actual application, such as Figure 4 As shown in the figure, the Ethernet protocol defines a 3-bit priority code point (PCP), which can represent 8 different priorities. The edge computing node can determine the first priority corresponding to the TSN service by parsing the PCP code.

[0051] In actual application, the terminal accesses the first base station, and the first base station forwards the terminal's TSN service request to the edge computing node. Based on this, in one embodiment, before receiving the TSN service data corresponding to each first terminal in at least one first terminal sent by the edge computing node, the method further includes:

[0052] receiving a TSN service request sent by each first terminal of the at least one first terminal;

[0053] The received TSN service request is sent to the edge computing node, so that the edge computing node parses the corresponding TSN service data based on the TSN service request.

[0054] Here, a first terminal connected to a first base station sends a TSN service request to the first base station. The first base station sends the received TSN service request to the edge computing node. In this way, after receiving the TSN service request, the edge computing node obtains the corresponding TSN service data and the corresponding first priority based on deep analysis. In actual application, the first base station can forward TSN service requests sent by multiple first terminals separately, and the edge computing node performs deep analysis on each received TSN service request.

[0055] Step 302: Based on the system clock of the first base station and according to the corresponding first priority, perform TSN service scheduling for the at least one first terminal.

[0056] Based on the analysis result of the edge computing node, the first base station combines its own system clock to uniformly schedule the TSN services requested by each first terminal based on the corresponding first priority.

[0057] In one embodiment, the performing TSN service scheduling for the at least one first terminal based on the system clock of the first base station and according to the corresponding first priority includes:

[0058] Putting the TSN service data corresponding to each first terminal in the at least one first terminal into the corresponding sending queue; wherein the first base station creates at least two sending queues; each sending queue in the at least two sending queues corresponds to a first priority;

[0059] Based on the system clock of the first base station and the first priority corresponding to each sending queue, each sending queue is controlled to send TSN service data.

[0060] Here, when scheduling TSN services, the first base station sets up multiple sending queues, that is, data transmission channels, and each sending queue corresponds to a first priority. Based on the first priority, the first base station sends the TSN service data to the corresponding sending queue and controls the data output of each sending queue through the switch gate mechanism, thereby realizing TSN service scheduling. Figure 5 The on / off gate mechanism controls the on / off state of each transmit queue at each moment. TSN service data in a transmit queue can only be sent when the corresponding transmit queue opens its gate. Therefore, based on the first base station's system clock, the first base station controls the corresponding transmit queue with the highest priority to open its gate first, and the corresponding transmit queue with the lowest priority to open its gate later, thus prioritizing the transmission of high-priority TSN service data and implementing TSN service scheduling based on the highest priority.

[0061] In one embodiment, when placing the TSN service data corresponding to each first terminal in the at least one first terminal into the corresponding sending queue, the method further includes:

[0062] Based on the order in which the first base station receives the TSN service data, the TSN service data corresponding to each first terminal in the at least one first terminal is arranged and placed into a corresponding sending queue.

[0063] Here, the first base station puts the first received TSN service data into the corresponding sending queue first and the later received TSN service data into the corresponding sending queue later based on the first-come-first-served order, so as to ensure the orderly processing of TSN service data.

[0064] In addition, to ensure that high-priority TSN services are scheduled first, in one embodiment, when arranging the TSN service data corresponding to each first terminal in the at least one first terminal into the corresponding sending queue based on the order in which the first base station receives the TSN service data, the method further includes:

[0065] The TSN service data with the highest priority is directly placed into the corresponding sending queue.

[0066] That is to say, in actual application, a threshold is reserved for the TSN service data with the highest first priority. The TSN service data does not need to queue in a first-come-first-served order to enter the corresponding sending queue. When the first base station receives the corresponding TSN service data with the highest first priority, the TSN service data is directly sent to the corresponding sending queue to ensure that the corresponding TSN service can be scheduled first with the minimum delay.

[0067] In actual application, in order to ensure that high-priority TSN services can have higher data carrying capacity, the first base station will uniformly schedule TSN services and wireless side services, that is, unify the TSN service priority and the wireless side service priority. Based on this, in one embodiment, before placing the TSN service data corresponding to each first terminal in the at least one first terminal into the corresponding sending queue, the method further includes:

[0068] The first field in the TSN service data is removed.

[0069] The first field is the first field representing the corresponding first priority carried in the TSN service data sent by the edge computing node to the first base station. Here, the first base station removes the first field carried in the TSN service data before sending the TSN service data to the corresponding sending queue. In this way, in actual application, TSN services and wireless side services can be scheduled through a unified sending queue setting, realizing unified scheduling of TSN services and wireless side services.

[0070] During the entire process of TSN service scheduling by the first base station, the system clock of the first base station is used as the time reference. In order to ensure clock synchronization between the first base station and the terminal, in one embodiment, the method further includes:

[0071] Determining a first duration based on the system clock; the first duration represents a time interval between data arriving at the first base station and data being sent from the first base station;

[0072] Time synchronization is performed with the first terminal based on the first duration.

[0073] For example, the clock of a 5G base station is precisely timed by the 5G core network. By calculating the required residence time of data at the gNB from the time it arrives at the gNB to the time it is sent from the gNB, the gNB can achieve precise time synchronization with the terminal.

[0074] Figure 6 The schematic diagram of the service scheduling process provided by the application embodiment of the present application is shown. Figure 6 :

[0075] Step 1: The UE initiates a service request to the edge computing node via the eNB, and carries the TSN Ethernet protocol in the service request.

[0076] Step 2: Based on the service request, the edge computing node identifies that the UE requests a local TSN service.

[0077] Step 3: The edge computing node performs in-depth analysis based on the service request to obtain the corresponding TSN service data and the corresponding first priority.

[0078] Step 4: The edge computing node encapsulates the deep analysis results to obtain a TSN service data packet and sends it to the eNB. The TSN service data packet carries a corresponding field representing the TSN service priority that can be identified by the eNB.

[0079] Step 5: The eNB sorts the received TSN service data packets based on the field representing the TSN service priority and sends them to the corresponding sending queue.

[0080] Step 6: The eNB controls each sending queue through the switch gate mechanism to schedule TSN services.

[0081] In actual application, for example, based on the TSN service scheduling of the first base station, the 5G terminal can be connected to one or more devices outside the 5G system, such as a robotic arm, a programmable logic controller (PLC), and other devices through a terminal-side TSN converter (DS-TT) to achieve further TSN scenario applications.

[0082] The service scheduling method provided in the embodiment of the present application uses the first base station to implement the TSN converter function, thereby sinking the deployment of the TSN converter from the UPF network element to the base station, reducing the latency of TSN services. In addition, through in-depth analysis of the edge computing node, the first base station can achieve autonomous base station-side bearer triggered by TSN priority, and can provide different levels of service quality assurance for the transmission of TSN services without going through the core network.

[0083] In order to implement the method of the embodiment of the present application, the embodiment of the present application further provides a service scheduling device, which is set on the first base station, such as Figure 7 As shown, the device includes:
