Description

TECHNICAL FIELD This application relates to the field of communication technologies, and in particular, to a task processing method and an apparatus. BACKGROUND In new radio (new radio, NR), a terminal device has three different radio resource control (radio resource control, RRC) states: an idle (idle) state, an inactive (inactive) state, and a connected (connected) state. In a future-oriented intelligent inclusive scenario, a cloud (for example, a central node of cloud computing), an edge (for example, an edge device of cloud computing), a device (for example, a terminal device), and the like of a network need to collaborate to perform task processing. However, existing task processing usually requires the terminal device to be in the connected state. Therefore, a terminal device in the inactive state needs to switch to the connected state to complete task processing. Frequent state switching causes problems such as a long delay, high signaling overheads, and high energy consumption. Therefore, how to reduce a delay, signaling overheads, and energy consumption of performing task processing by the terminal device is a problem that needs to be considered. SUMMARY This application provides a task processing method and an apparatus, to support a terminal device in performing task processing in an inactive state, and reduce a delay, signaling overheads, and energy consumption of performing task processing by the terminal device. According to a first aspect, an embodiment of this application provides a task processing method. The method includes: A first communication apparatus receives a task, where the task is a non-session task, and the first communication apparatus or a second communication apparatus that participates in the task is in an inactive state; the first communication apparatus obtains first task data obtained by executing the task; and when sending of the first task data meets a first condition, the first communication apparatus sends the first task data to the second communication apparatus based on a small data transmission mechanism. In the foregoing task processing method, the first communication apparatus may be a terminal device, a component (for example, a processor, a chip, or a chip system) of a terminal device, or an apparatus used in combination with a terminal device; and the second communication apparatus may be a network device, a component (for example, a processor, a chip, or a chip system) of a network device, or an apparatus used in combination with a network device. Alternatively, the first communication apparatus may be a network device, a component (for example, a processor, a chip, or a chip system) of a network device, or an apparatus used in combination with a network device; and the second communication apparatus may be a terminal device, a component (for example, a processor, a chip, or a chip system) of a terminal device, an apparatus used in combination with a terminal device, or the like. A communication apparatus corresponding to the terminal device, the component (for example, the processor, the chip, or the chip system) of the terminal device, or the apparatus used in combination with the terminal device is in the inactive state. According to the foregoing method, the terminal device in the inactive state is enabled to complete the task based on the small data transmission mechanism. In comparison with a case in which the terminal device needs to switch to a connected state to perform task processing, a quantity of switching times of the terminal device between the inactive state and the connected state can be effectively reduced, thereby reducing the delay, the signaling overheads, and the energy consumption of the terminal device during task processing. In a possible design, that sending of the first task data meets the first condition includes: a data volume of the first task data is less than or equal to a first threshold. It may be understood that, when the first communication apparatus receives a plurality of tasks, and the first communication apparatus executes the plurality of tasks to obtain a plurality of pieces of first task data, if the first communication apparatus sends the plurality of pieces of first task data together based on the small data transmission mechanism, a total data volume of the plurality of pieces of first task data should be less than or equal to the first threshold; or if the first communication apparatus separately sends the plurality of pieces of first task data based on the small data transmission mechanism, a data volume of each first task in the plurality of pieces of first task data should be less than or equal to the first threshold. According to the foregoing design, it can be ensured that the task data sent based on the small data transmission mechanism meets a transmission data volume threshold of the small data transmission mechanism, and reliability of task data transmission is ensured. In a possible design, the first th
