Description

Method, device, equipment and system for saving energy of access point Technical Field The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a system for energy saving of an access point. Background Wireless local area networks (wireless local area network, WLAN) are becoming more and more popular, and WLAN includes Stations (STAs) and Access Points (APs), and energy saving is focused on energy saving of the stations at present, so as to prolong the standby time of the stations. For example, the access point periodically broadcasts a beacon (beacon) frame, the beacon frame includes indication information of whether each station has downlink data, the station only needs to wake up periodically at the beacon frame time point, receives the beacon frame, judges whether the downlink data exists, if so, enters a working state, and if not, continues to sleep. As the functions of the access point are gradually increased, the power consumption problem thereof becomes prominent, and thus, how to reduce the power consumption of the access point is important. Disclosure of Invention The application provides a method, a device, equipment and a system for saving energy of an access point, which can reduce the power consumption of the access point. The technical scheme adopted is as follows: In a first aspect, the application provides a method for power saving of an access point, applied to a first access point in a fiber-to-room (Fiber to the Room, FTTR) network, the first access point being connected with at least one other access point in the FTTR network, the method comprising sending a first power saving control message to a second access point in the at least one other access point, wherein the power saving control message is used for instructing the second access point to perform a first power saving operation, receiving service state information sent by the second access point, wherein the service state information is used for adjusting the power saving operation of the second access point during power saving. In the scheme shown in the application, in FTTR networks, the first access point instructs the second access point to save energy. But also may receive traffic state information reported from the access point, which is used to adjust the power saving operation of the second access point. Therefore, the access point can save energy, and the energy-saving operation of the access point can be dynamically adjusted based on the service state information, so that the influence of energy saving on the service of the access point is reduced as much as possible. In an alternative manner, after receiving the service status information sent by the second access point, the first access point determines the energy saving operation of the second access point by using the service status information, and if the currently determined energy saving operation is different from the energy saving operation executed by the current second access point, sends an energy saving control message to the second access point to instruct the second access point to switch the energy saving operation. Thus, the first access point can dynamically adjust the energy-saving operation of the access point based on the service state information, and the influence of energy saving on the service of the access point is reduced as much as possible. In an alternative manner, the traffic state information includes one or more of a data transmission case, a data reception case, or a traffic delay. The data sending condition, the data receiving condition or the service time delay can reflect the network experience of the station, so that the energy-saving operation of the second access point is adjusted based on the information, and the influence on the service is reduced or avoided when energy is saved as much as possible. In an alternative approach, the data transmission conditions include a transmission condition of a physical layer protocol data unit (PHYSICAL LAYER protocol data unit, PPDU) and/or a transmission condition of a medium access control protocol data unit (medium access control protocol data unit, MPDU). Wherein, the PPDU is mainly used for data transmission of a physical layer, and the MPDU is mainly used by a medium access control (medium access control, MAC) layer. The transmission condition of the PPDU and the transmission condition of the MPDU directly reflect the network quality, so that the energy-saving operation of the access point is adjusted based on the transmission condition of the PPDU and the transmission condition of the MPDU, and the influence on the service is reduced or avoided as much as possible during energy saving. In an alternative manner, the transmission case of the PPDU includes a retransmission rate of the PPDU. The retransmission rate of the PPDU directly reflects the network quality, so that the energy-saving operation of the ac
