Description

A scheduling method and a scheduling device This application claims priority to Chinese Patent Application No. 202411564934.8, filed with the State Intellectual Property Office of China on November 4, 2024, entitled “A Scheduling Method and Scheduling Device”, the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of optical communication technology, and in particular to a scheduling method and scheduling device. Background Technology In a wireless local area network (WLAN), a control node connects to multiple network nodes. WLAN networks can reduce air interface contention between multiple network nodes (or between multiple network nodes and the control node) through time-domain coordinated transmission. Time-domain coordinated transmission refers to the coordinated air interface transmission between the control node and network nodes in the time domain. In the time-domain cooperative transmission scheme, the control node determines the air interface transmission order of different network nodes and schedules the network nodes sequentially, thereby staggering the Wi-Fi air interfaces of different network nodes in time. This can reduce conflicts and efficiency degradation caused by air interface contention between multiple network nodes (or between multiple network nodes and the control node), providing a stable and reliable connection for terminal devices. In a time-domain coordinated transmission scheme, time-domain scheduling for the next air interface (including scheduling, air interface contention, and service transmission phases) must be initiated only after the time-domain scheduling of the previous air interface is completed. If the air interface is blocked in the previous air interface due to reasons such as low service priority of network nodes or air interface congestion (e.g., scheduling, air interface contention, or service transmission processes are blocked), then the scheduling of the next air interface and even subsequent air interfaces will be delayed, affecting subsequent air interface transmission and impacting service experience. Summary of the Invention This application provides a scheduling method and scheduling device for early termination of air interface contention, thereby reducing network congestion and improving the overall network performance of the wireless network. In a first aspect, this application provides a scheduling method, the method comprising: a control node sending a first message to a first network node, wherein a first field of the first message is used to instruct the first network node to terminate air interface contention; and the control node receiving a second message from the first network node, wherein a second field of the second message is used to indicate whether the air interface contention was successfully terminated. In this embodiment, the control node sends a first message to the first network node of the current air interface to terminate the current air interface (including scheduling, air interface contention, service transmission, etc.). This scheme can promptly terminate the current air interface in cases of abnormal blocking or higher-priority service requests for air interface transmission, thereby ensuring the timely operation of the next air interface and even subsequent air interfaces. Preventing the entire network's air interface transmission queue from being blocked by the current air interface can improve the overall network transmission rate, thereby enhancing the user experience. In one possible design, if the second field indicates successful termination of air interface contention, then after receiving the second message from the first network node, the control node sends a first scheduling message, which instructs either the first network node or the second network node to transmit the second service data over the air interface. In this embodiment, the control node schedules a new air interface after the first network node successfully terminates air interface contention. This allows for the timely opening of the next air interface after terminating the current one, reducing the waiting latency for the next air interface, improving the overall network transmission rate, and thus enhancing the user experience. In one possible design, before sending the first message to the first network node, the control node sends a first scheduling message to the first network node. The first scheduling message is used to instruct the first network node to transmit first service data over the air interface. The step of the control node sending the first message to the first network node may specifically include: if the time elapsed since sending the first scheduling message exceeds a first duration, then the control node sends the first message to the first network node. In this embodiment, the timer starts when the control node sends a time allocation message to the first network no
