Description

Energy-saving control method, device, equipment and system of access point The present application claims priority from chinese patent application with application number 202411570010.9, application name "energy saving control method, apparatus, device and system for access point", whose application number is 2024, 11, 04, and the entire contents of this patent application are incorporated herein by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to an energy saving control method, apparatus, device, and system for 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. The number of access points in WLAN is gradually increased, and the functions of the access points are also gradually increased, so that the problem of power consumption of the access points becomes prominent. Accordingly, there is a need to provide a solution that reduces access point power consumption. Disclosure of Invention The application provides an energy-saving control method, device, equipment and system of an access point, and provides a scheme for reducing power consumption of the access point. The technical scheme adopted is as follows: In a first aspect, the present application provides a method of power saving control of an access point for a first access point in a fibre-to-room (fiber to the room, FTTR) network, the first access point being connected to at least one access point in the FTTR network, the method comprising sending a power saving control message to a second access point of the at least one access point to cause the second access point to perform a power saving operation, wherein the power saving control message comprises one or more of a number of spatial streams, a turn-off capability or a bandwidth of the second access point. In the scheme shown in the application, the first access point instructs the second access point to perform energy-saving operation, and the energy-saving control message includes one or more of the number of spatial streams, the turn-off capability or the bandwidth of the second access point. In this way, the second access point can be instructed on how to perform power saving operation, reducing power consumption. And under the condition of limited flow and same air interface transmitting power, the smaller the number of the space flows is, the lower the power consumption is. The bandwidth is also called bandwidth, and indicates the bandwidth occupied by transmitting data, and in the case of a certain traffic size, the smaller the occupied bandwidth is, the lower the power consumption is. The shutdown capability indicates whether to shutdown the power save object of the second access point. In this way, since the power consumption can be reduced after the energy saving object is turned off, energy can be saved by turning off the energy saving object. In an alternative way, the energy saving control message further comprises an indication identifier for indicating whether the low power listening capability is provided. The low-power interception capability refers to the capability of intercepting with low power. When the low-power interception capability is provided, the power consumption is lower, and when the low-power interception capability is not provided, the power consumption is higher, so that the power consumption can be reduced by indicating whether the low-power interception capability is provided. In an alternative, the power saving control message further includes a time period required to switch from the low power listening mode to the normal operating state. Therefore, the energy-saving object can be restored to the normal working state in time, and the influence on the service is reduced. In an alternative way, the energy saving control message further comprises a null transmit power and/or a modulation and coding scheme. The air interface transmitting power refers to the power when air interface transmitting is adopted, and the smaller the air interface transmitting power is, the lower the power consumption is. The lower the complexity of the modulation and coding scheme, the lower the power consumption under a certain traffic size. Thus, different energy saving magnitudes can be achieved by adjusting these parameters. In an alternative, the power saving control message f
