Description

Method, device, access point 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, an access point, and a system for saving energy 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. As access points in WLANs increase and the functionality of access points increases, the problem of power consumption of access points becomes prominent. Therefore, there is a need to reduce the power consumption of access points. Disclosure of Invention The application provides an energy-saving method, device, access point and system for an access point, which can reduce the power consumption of the access point. The technical scheme adopted is as follows: In a first aspect, a method for saving energy of an access point is provided, which is applied to a first access point in FTTR networks, where the first access point is connected with at least one other access point in FTTR networks, and the method includes that the first access point receives energy saving statistical information sent by at least one access point, where the energy saving statistical information includes site information and/or service information, and further the first access point can make an energy saving decision according to an energy saving state of the at least one access point. In the scheme shown in the application, the first access point acquires energy-saving statistical information from at least one other access point connected with the first access point, the energy-saving statistical information is used for determining the energy-saving state of at least one other access point (such as a second access point), and then the first access point indicates the second access point to save energy according to the energy-saving state of the second access point. In this way, not only can the power consumption of the second access point be reduced, but also the energy saving state is matched with the second access point because the energy saving state is determined based on the energy saving statistical information of the second access point, thereby being capable of reducing the influence on the service. In an alternative manner, the station information includes one or more of association information of stations on at least one access point, perception information of unassociated stations by at least one access point, or traffic information of stations. The association information can reflect information such as the number of stations associated with the access point, frequency bands and the like, and in general, the more the number of stations is, the more resources are needed, so that the association information can be used as a reference condition for energy saving decision. The perceived information of the stations of the unassociated points by the at least one access point can assist in judging whether the nearby access points are unassociated, and in the case of unassociated stations, the stations may roam to the at least one access point, so that deep energy conservation may not be realized in the energy conservation decision. The traffic information of the station can reflect the data amount required to be transmitted by the station, and in general, the larger the data amount is, the more resources are required, so that the traffic information can be used as a reference condition for energy saving decision. The content of the site information is directly related to the energy-saving state, so that the energy-saving state is determined by using the site information, the proper energy-saving state can be determined, and the influence on the site is reduced. In an alternative, the site information includes air interface information for the site. Because the station and at least one access point transmit data through the air interface, the judgment of the energy-saving state by the air interface information also has an influence, so that the air interface information can be used as a reference condition for energy-saving decision, and the influence on the station is reduced. In an alternative manner, the air interface information includes one or more of dormancy information, link related information, or supported transceiving parameters for stations on at least one access point. The station can transmit a large amount of data only when the station is not dormant, so that the energy saving of the access point and the synchronization of the station dormancy can be considered, and the influence on the station is reduced. The link adopted by the station for transmitting the data may indirectly reflect the service type of the data transmitted by the station, so that th
