Description

Method, device, access point and system for feeding back access point state The present application claims priority from chinese patent application with application number 202411570007.7, application number "method, apparatus, access point and system for access point status feedback" and application number 2024, 11, 29, application number 202411751484.3, application number "method, apparatus, access point and system for access point status feedback", all of which are incorporated herein by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, an access point, and a system for feeding back a state of an access point. Background Wireless local area networks (wireless local area network, WLANs) are becoming more and more popular, and WLANs include Stations (STAs) and Access Points (APs), where a master access point and a slave access point exist, and the master access point is connected to the slave access point, and the master access point may need to acquire information from the slave access point, so that a way to acquire information needs to be provided. Disclosure of Invention The application provides a method, a device, an access point and a system for feeding back the state of an access point, which can enable a master access point to acquire the state of a slave access point, thereby better controlling the slave access point. In a first aspect, a method of access point state feedback is provided, the method being applied to a first access point in a fiber-to-the-room FTTR network, the first access point being connected to at least one other access point in the FTTR network, the method comprising the first access point receiving a first state sent by a second access point in the at least one other access point, wherein the first state is an operational state, a power saving state, or a power saving ready state. The first access point performs a state synchronization operation. In the scheme shown in the application, the first access point can be used as a master access point, other access points can be used as slave access points, and the first state is a working state, an energy-saving state or an energy-saving preparation state, so that the energy-saving condition of the slave access points can be indicated. In this way, the master access point can acquire the first state of the slave access point, so that the master access point can know the energy saving condition of the slave access point and better control the energy saving of the slave access point. In an alternative manner, the first access point sends a status query request to the second access point before receiving the first status sent by the second access point in the at least one other access point, wherein the status query request is used to query the status of the second access point. In this way, the first access point may actively query the second access point for its status. In an alternative approach, the first access point determines that the second access point is brought back online after being brought offline before sending a status query request to the second access point. Or the first access point determines that the second access point does not report the state at the appointed time point. Thus, the first access point can timely acquire the state of the second access point, and further can timely perform energy-saving control on the second access point. In an alternative manner, the first access point receives a first state sent by a second access point in the at least one other access point, including the first access point receiving a first state sent by the second access point after switching states. Or the first access point receives the first state periodically transmitted by the second access point. Or the first access point receives the first state sent by the second access point after offline and online again. Therefore, under different conditions, the first access point can acquire the state of the second access point in time, and the energy-saving control is better carried out on the second access point. In an alternative approach, the first access point receives a first state transmitted by a second access point of the at least one other access point, including the first access point receiving a first state transmitted by the second access point during the synchronization phase. Thus, the first access point can also acquire the first state of the second access point in the synchronization stage of the second access point, and further the flexibility of the first access point to acquire the first state of the second access point can be increased. In an optional manner, the first access point receives a first state sent by a second access point in at least one other access point, and the first access point receives a state report message sent by the second access point, wherein the state report message comprises an identifi
