Description

Optical network communication method and communication device The present application claims priority from chinese patent application filed 11.04.2024, filed 11.04 with chinese national intellectual property office, application number 202411569873.4, application name "an optical network communication method and communication device", the entire contents of which are incorporated herein by reference. Technical Field The embodiment of the application relates to the field of optical communication, in particular to an optical network communication method and a communication device. Background Fiber-to-room (fiber to the room, FTTR) refers to a technique of providing fiber medium access to a room downstream of an optical network device (e.g., an optical network terminal (optical network terminal, ONT)) with fiber instead of a network cable. The fiber optic network in this FTTR scenario includes a master device and one or more slave devices (also referred to as sub-devices). The master device and the slave device can establish a management channel, so that the master device can send a message related to management or control to the slave device through the management channel, and the management or control of partial functions of the slave device by the master device is realized. For example, a management channel can be established WMCI between the master device and the slave device based on a wireless local area network management and control interface (WLAN MANAGEMENT control interface, WMCI) protocol, so that messages can be interacted WMCI between the master device and the slave device through the WMCI management channel, thereby realizing management or control of wireless local area network (wireless local area network, WLAN) functions. In the current standard, the format of WMCI messages is not well defined, which is detrimental to the efficient management of slave devices by the master device. Disclosure of Invention The application provides an optical network communication method and a communication device, which are beneficial to improving the management and control efficiency of a master device and a slave device by defining indication information to indicate WMCI the operation type of a message. In a first aspect, the present application provides an optical network communication method applied to an optical fiber network, where the optical fiber network includes a master device and at least one slave device, and the at least one slave device includes a first slave device. The optical network communication method provided in the present aspect may be executed by a host device in the optical fiber network, or may be executed by a part of functional modules or chips in the host device. Taking the execution of the master device as an example, the master device sends a first message to the first slave device, where the first message is a message of the WLAN management control interface WMCI, the first message is used to manage or control the WLAN function of the first slave device, and the first message includes first indication information, where the first indication information is used to indicate the operation type of the first message. In this aspect, the first message sent by the master device to the first slave device carries the first indication information, where the first indication information indicates the operation type of the first message, so that it is beneficial for the first slave device to quickly decide whether to generate the response message of the first message based on the first indication information, thereby improving the communication efficiency between the master device and the slave device, and further improving the management and control efficiency of the master device on the slave device. In a possible embodiment, the operation type of the first message includes a parameter request type, i.e. the first indication information indicates that the operation type of the first message is a parameter request type. The parameter request type indicates that the master device requests the first slave device to transmit the parameter of the first slave device to the master device, i.e., the parameter requiring the first slave device to transmit the first slave device to the master device. It will be appreciated that a parameter request type message (e.g., a first message) is a message that requests a receiving end (e.g., a first slave device) to report one or more parameters, and thus requires the receiving end (e.g., the first slave device) to send the parameter requested by the first message to an originating end (e.g., a master device). The foregoing parameter may be an intrinsic parameter of the first slave device, or a parameter configured by the master device for the first slave device, which is not limited herein. In this embodiment, the operation type of the first message sent by the master device to the first slave device is a parameter request type, so as to enable the first slav
