Abstract

This application discloses a data transmission method, a device, a readable storage medium, and a program product, and relates to the field of terminal technologies. In this application, when the device receives a data packet of a service of a first service type, if a QoS control function corresponding to the first service type is already set by a user to an enabled state, and a currently used APN includes a first APN allocated for the first service type, the device determines a first dedicated bearer corresponding to the first APN, and performs transmission of the data packet on the first dedicated bearer. It can be learned that, in this application, the user determines whether to perform QoS control on a service of a type. When the user determines to perform QoS control on a service of a service type, the device performs transmission of data of the service of the service type on a dedicated bearer for a dedicated APN corresponding to the service type, to guarantee quality of service of the service of the service type, achieve user-intention-based QoS guarantee, and improve user experience.

Description

This application claims priority to Chinese Patent Application No. 202410642803.0, filed with the China National Intellectual Property Administration on May 22, 2024 and entitled "DATA TRANSMISSION METHOD, DEVICE, READABLE STORAGE MEDIUM, AND PROGRAM PRODUCT", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of terminal technologies, and in particular, to a data transmission method, a device, a readable storage medium, and a program product. BACKGROUND Currently, devices such as smartphones and tablet computers may be connected to a network via customer premises equipment (customer premises equipment, CPE). A quantity of devices connected to the CPE is usually large, and requirements of services run on different devices may vary. For example, services run on some devices require low data transmission latency. For another example, services run on some devices require large transmission bandwidth. In view of this, how to guarantee a requirement of a service of a device connected to the CPE is an urgent problem to be resolved. SUMMARY This application provides a data transmission method, a device, a readable storage medium, and a program product, to achieve QoS guarantee of a service of a specified service type based on user selection, and improve user experience. To achieve the foregoing objective, this application uses the following technical solutions. According to a first aspect, a data transmission method is provided, which is applied to a device. The method includes: receiving a first data packet, where a service type of a first service to which the first data packet belongs is a first service type; if a quality of service (quality of service, QoS) control function corresponding to the first service type is in an enabled state, and a currently used access point name (access point name, APN) includes a first APN, determining a first dedicated bearer corresponding to the first APN, where the first APN is an APN allocated to a service of the first service type, and the enabled state of the QoS control function is preset by a user; and performing transmission of the first data packet on the first dedicated bearer. It should be understood that the device includes but is not limited to CPE. The first service type may be a latency-first type or a bandwidth-first type. The latency-first means that there is a high latency requirement, and the bandwidth-first means that there is a high bandwidth requirement. The latency-first type may include game, conference, real-time video, and the like. The bandwidth-first type may include video download, large file download, and the like. Correspondingly, the first service type may alternatively be any one of the foregoing latency-first types, or any one of the foregoing bandwidth-first types. Optionally, the method further includes: receiving a second data packet, where a service type of a second service to which the second data packet belongs is a second service type, and the second service type is different from the first service type; if a quality of service QoS control function corresponding to the second service type is in an enabled state, and the currently used access point name APN includes a second APN, determining a second dedicated bearer corresponding to the second APN, where the second APN is an APN allocated to a service of the second service type; and performing transmission of the second data packet on the second dedicated bearer. The second service type is different from the first service type. For example, the first service type is a latency-first type, and the second service type is a bandwidth-first type; or the first service type and the second service type are different types included in the latency-first type or the bandwidth-first type. For example, the first service type is the game, and the second service type is the conference. In this application, when a data packet of the service of the first service type is received, if the QoS control function corresponding to the first service type is already set by the user to the enabled state, and a currently used APN is the first APN allocated to the first service type, the first dedicated bearer corresponding to the first APN may be determined, and transmission of the data packet is performed on the first dedicated bearer. It can be learned that, in this embodiment of this application, the user may determine whether to perform QoS control on a service of a type. When the user determines to perform QoS control on a service of a type, transmission of data of the service of the type is performed on a dedicated bearer for a dedicated APN corresponding to the service type, to guarantee quality of service of the service of the type, achieve user-intention-based QoS guarantee, and improve user experience. Optionally, before receiving the first data packet, the method further includes: when detecting that the QoS control function corresponding to the
