Description

Scheduling method and scheduling device 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 air interface competition 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 application provides a scheduling method, which comprises the steps that a control node sends a first message to a first network node, a first field of the first message is used for indicating the first network node to terminate air interface competition, and the control node receives a second message from the first network node, and a second field of the second message is used for indicating whether the air interface competition is successfully terminated or not. In the embodiment of the application, the control node sends the first message to the first network node of the current air interface, and the termination of the current air interface (including the stages of scheduling, air interface competition, service transmission and the like) is realized. 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, if the second field indicates that termination of the air interface contention is successful, the control node sends a first scheduling message after the receiving of the second message from the first network node, where the first scheduling message is used to instruct the first network node or the second network node to transmit second service data on the air interface. In the embodiment of the application, the control node schedules a new air interface under the condition that the first network node successfully terminates the air interface competition. The next air interface can be opened in time after the current air interface is terminated. Therefore, the waiting time delay of the next air interface is reduced, the transmission rate of the whole network can be improved, and the user experience is improved. In one possible design, before the first message is sent to the first network node, the control node sends a first scheduling message to the first network node, where the first scheduling message is used to instruct the first network node to transmit first service data on an air interface, and the step of sending the first message to the first network node by the control node may specifically include sending the first message to the first network node if the time from the sending of the first scheduling message exceeds a first time length. In the embodiment of the application, the t
