Description

Scheduling method and scheduling device The present application claims priority from chinese patent application with application number 202411563183.8, application number "a scheduling method and scheduling apparatus", whose entire contents are incorporated herein by reference, on application day 2024, 11/04. Technical Field The embodiment of the application relates to the technical field of optical communication, in particular to a scheduling method and a scheduling device. Background In a wireless local area network (wireless local area network, WLAN), a control node is connected to a plurality of network nodes. The WLAN network may reduce air interface contention between multiple network nodes (or between multiple network nodes and a control node) through time domain cooperative transmission. And the time domain cooperative transmission refers to the air interface transmission cooperation of the control node and the network node in the time domain. In the time domain cooperative transmission scheme, a control node determines the air interface transmission sequence of different network nodes and sequentially schedules the network nodes, so that Wi-Fi air interfaces of the different network nodes are staggered in time. Collisions and efficiency degradation caused by air interface competition among a plurality of network nodes (or between a plurality of network nodes and a control node) can be reduced, and stable and reliable connection is provided for terminal equipment. In the time domain cooperative transmission scheme, time domain scheduling of the next air interface (including scheduling, air interface competition, service transmission and other stages) needs to be started after time domain scheduling of the last air interface is completed. If the air interface is blocked (e.g., scheduling, air interface contention, traffic transmission, etc. are blocked) due to the low traffic priority of the network node and the busy air interface. The scheduling of the next air interface and even the subsequent air interface will be delayed, affecting the subsequent air interface transmission and affecting the service experience. Disclosure of Invention The embodiment of the application provides a scheduling method and a scheduling device, which are used for terminating a current air interface in advance, so that the blocking in a network is reduced, and the whole network performance of a wireless network is improved. In a first aspect, the present application provides a scheduling method, where a first network node receives a first message, and switches from a scheduled state to a null interface contention decision state according to a first field of the first message, where the scheduled state is a state in which the first network node is scheduled to transmit first service data through a null interface, the null interface contention decision state is a state in which the first network node decides whether to terminate null interface contention, the first field of the first message is used to indicate the first network node to terminate null interface contention, and if the null interface contention is successfully terminated by the first network node, the first network node switches from the null interface contention decision state to a state to be scheduled, and the state to be scheduled is a ready state in which the first network node performs null interface transmission, and if the null interface contention is failed by the first network node, the first network node switches from the null interface contention decision state to the scheduled state. In the embodiment of the application, the first network node terminates the current air interface (including the stages of scheduling, air interface competition, service transmission and the like) in advance according to the first message. According to the scheme, the current air interface can be terminated in time under the conditions that the current air interface is blocked due to abnormality, the transmission of the air interface is requested by the service with higher priority, and the like, so that the next air interface and even more subsequent air interfaces can be guaranteed to run in time. The air interface transmission queue of the whole network is prevented from being blocked by the current air interface, so that the transmission rate of the whole network can be improved, and the user experience is improved. In one possible design, the scheduled states include a scheduling and air interface contention state and a traffic transmission state, where the scheduling and air interface contention state is a state in which the first network node performs scheduling and air interface contention, and the traffic transmission state is a state in which the first network node transmits the first traffic data through an air interface. In the embodiment of the application, the scheduled states of the first network node comprise a scheduling and air interface competition
