In this embodiment, the base station may determine the service type of the current service based on the configuration information of the current service and the preset identifier set, and the method may simply and effectively implement the type discrimination of the current service and provide data support for data distribution of different services.
Based on the result of determining the service type of the current service in the foregoing embodiment, the base station performs corresponding data operation, and in an embodiment, the service type of the current service further includes the following cases:
and under the condition that the service type of the current service is other services, performing data processing on the current service according to an enhanced mobile broadband eMBB data processing rule.
In this embodiment, the base station may invoke different data processing units to perform different data processing operations on the data of each service after offloading based on different data processing rules. For example, the base station includes a URLLC data processing unit and an eMBB data processing unit. According to one condition in step 203, the base station, when determining that the current service is the TSN service, branches the data stream corresponding to the TSN service to the URLLC data processing unit, so that the URLLC data processing unit performs data processing of each protocol layer according to the URLLC data processing rule; in another case, when the base station determines that the current service is another service, the base station branches the data stream corresponding to the service to the eMBB data processing unit, so that the eMBB data processing unit performs data processing of each protocol layer according to the eMBB data processing rule. Optionally, the data processing priority of the TSN traffic is higher than the data processing priority of other traffic.
In this embodiment, the data stream splitting processing corresponding to each of the TSN service and the other service is implemented according to the service types of the TSN service and the other service, and the corresponding data is processed according to different data processing rules, so that the data of the TSN service can be ensured to obtain better data processing quality.
In a scenario where the base station performs uplink data processing, in order to ensure the service quality of the TSN service, the base station may further reserve a certain air interface resource for the TSN service, and ensure the processing priority of the TSN service, in an embodiment, the method further includes:
and reserving air interface resources with the specified time window length for the TSN service under the condition that the current service is determined to be the TSN service.
In this embodiment, when determining that the current service is a TSN service, the base station reserves uplink and downlink air interface resources of a specified time window length for the TSN service; optionally, in the case that the current service is determined to be another service, the resource is not reserved.
Optionally, the air interface resource is released when a session deletion message or a terminal deletion message is received.
In this embodiment, correspondingly, a URLLC PDU session is established correspondingly to the TSN service, and if the base station receives a request for indicating a URLLC PDU session deletion message or for indicating a terminal initiating the TSN service to delete a message, the base station releases the reserved uplink and downlink air interface resources.
In this embodiment, the base station reserves the air interface resource in a dynamic manner, so that the waste of the resource is reduced, the air interface resource is better prevented from being occupied statically, and the utilization efficiency of the air interface resource is improved.
Optionally, in an embodiment, as shown in fig. 4, the method for determining the length of the designated time window includes:
s401, determining that the uplink data arrival time of the terminal is located at the position of the uplink scheduling window.

S402, adjusting the uplink data arrival time of the terminal to be located in the region from the position of the uplink scheduling window to the target position.
In this embodiment, corresponding adjustment is performed according to the difference that the uplink data arrival time of the terminal is located at the position of the uplink scheduling window. The uplink data arrival time of the terminal at the position of the uplink scheduling window can be divided into the following two cases:
one of them is: if the uplink data arrival time of the terminal is located at the leftmost time point of the uplink scheduling window, moving the scheduling window to the left for a preset time length until the uplink data arrival time of the terminal is located in a target time region of the uplink scheduling window; the target position area is other time areas except the leftmost time point in the uplink scheduling window.
The other one is: if the uplink data arrival time of the terminal is located at other positions of the uplink scheduling window, determining the uplink data arrival time of the terminal as the midpoint of the uplink scheduling window; the other positions are any positions in other time regions except the leftmost time point in the uplink scheduling window.
In this embodiment, the time when the base station acquires that the uplink data arrives is located at the position of the uplink scheduling window, and if the time when the uplink data arrives is located at the leftmost side of the window, it is described that the scheduling opportunity given by the maximum rate is later than the time when the terminal data requests to be sent. And the base station moves the whole scheduling window to the left by a certain distance, and judges whether the position of the uplink data reaching time in the uplink scheduling window is still positioned at the leftmost side of the window or not again, wherein the base station moves the whole scheduling window to the left by a certain distance which can be determined according to actual conditions.
In this embodiment, if the base station determines that the time of the uplink data arrival is located in any position in the other time region except the leftmost time point, in this case, because the data arrival has a certain jitter, the base station may use the arrival time as a midpoint, so as to adjust the scheduling window according to the jitter amplitude.
And S403, determining the length of the scheduled time window at the position of the uplink scheduling window based on the adjusted uplink data reaching time.
In this embodiment, the base station may determine the position of the adjusted uplink data arrival time in the uplink scheduling window, and may determine the length of the scheduling time window by using the position as a reference point.

In this embodiment, for example, the first TSN packet is a TSN packet sent by the terminal last time, the second TSN packet is a TSN packet sent by the current terminal, the base station parses the TSN packet sent by the current terminal, parses the second generation time from the payload, and obtains a second arrival time of the TSN packet sent by the current terminal. Optionally, the base station may obtain a first generation time and a first arrival time corresponding to the first TSN packet based on the historical data, which is not limited in this embodiment.
S502, determining the length of a scheduled time window according to the first generation time, the first arrival time of the base station, the second generation time, the second arrival time of the base station and the adjusted uplink data arrival time at the position of an uplink scheduling window.
In this embodiment, the base station determines the time jitter amplitude of data packet transmission based on the generation time and the arrival time of the data packets received twice in the vicinity of the base station, so as to predict the position where the next data packet arrives at the base station, and further more accurately reserve an air interface resource with a specified time window length for data transmission of the TSN service, optionally, the specific manner of determining the scheduled time window length includes, as shown in fig. 6, determining the scheduled time window length at the position of the uplink scheduling window according to the first generation time, the first arrival time at the base station, the second generation time, the second arrival time at the base station, and the adjusted uplink data arrival time, and includes:
