Description

Methods, devices, access points, and systems for access point status feedback This application claims priority to Chinese patent applications filed on November 4, 2024, with application number 202411570007.7 and entitled "Method, Apparatus, Access Point and System for Access Point Status Feedback", and filed on November 29, 2024, with application number 202411751484.3 and entitled "Method, Apparatus, Access Point and System for Access Point Status Feedback", and filed on January 9, 2025, with application number 202510041002.3 and entitled "Method, Apparatus, Access Point and System for Access Point Status Feedback", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of communication technology, and in particular to a method, apparatus, access point, and system for access point status feedback. Background Technology Wireless local area networks (WLANs) are becoming increasingly popular. WLANs include stations (STAs) and access points (APs). Among the access points, there are master access points and slave access points. The master access point is connected to the slave access point. The master access point may need to obtain information from the slave access point, so a way to obtain information is needed. Summary of the Invention This application provides a method, apparatus, access point, and system for access point status feedback, which enables the master access point to obtain the status of the slave access point, thereby enabling better control of the slave access point. In a first aspect, a method for access point status feedback is provided. This method is 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 includes: the first access point receiving a first status sent by a second access point among the at least one other access point, wherein the first status is an operational status, an energy-saving status, or an energy-saving preparation status. The first access point then performs a status synchronization operation. In the scheme shown in this application, the first access point can be used as the master access point, and the other access points can be used as slave access points. The first state is either working state, energy-saving state, or energy-saving preparation state, which can indicate the energy-saving status of the slave access points. In this way, since the master access point can obtain the first state of the slave access points, the master access point can understand the energy-saving status of the slave access points and better control the energy saving of the slave access points. In one alternative approach, before receiving a first status from a second access point (at least one other access point), the first access point sends a status query request to the second 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 can proactively query the second access point for its status. In one alternative approach, before sending a status query request to the second access point, the first access point determines that the second access point has come back online after being offline. Alternatively, the first access point determines that the second access point has not reported its status at a specified time. This allows the first access point to obtain the status of the second access point promptly, enabling it to implement energy-saving control measures accordingly. In one alternative approach, the first access point receives a first status sent by a second access point among at least one other access point, including: the first access point receiving the first status sent by the second access point after a state switch; or, the first access point receiving the first status sent periodically by the second access point; or, the first access point receiving the first status sent by the second access point after it has gone offline and come back online. In this way, the first access point can obtain the status of the second access point in a timely manner under different circumstances, enabling better energy-saving control of the second access point. In one alternative approach, the first access point receives a first state sent by a second access point among at least one other access point, including: the first access point receiving the first state sent by the second access point during a synchronization phase. This allows the first access point to also acquire the first state of the second access point during the synchronization phase, thereby increasing the flexibility of the first access point in acquiring the first state of the second access point. In one alternative approach, the first access point receives a first status sent by at least one second access point, including: the first access point receiving a
