Technical Field The present application relates to the field of optical communications technologies, and in particular, to a method, an apparatus, a device, and a system for synchronizing signaling messages in a communication system. Background In a wireless access scenario, a coverage area of a single Access Point (AP) is limited, and in a larger area or an area with a high requirement on network quality, a plurality of access points are typically deployed, where the plurality of access points provide a unified wireless network access service. For example, within a building, multiple sets of fiber-to-room (fiber to the room, FTTR) systems are deployed, with FTTR devices in the multiple sets FTTR providing uniform wireless network access services. However, as the demand for wireless networks increases, the number of access points in a communication system increases, and each access point periodically or suddenly transmits signaling messages (e.g., management frames, control frames, etc.). In the case of a large number of access points in the wireless network, since each access point needs to contend for the air interface to transmit the signaling message, unnecessary contention and collision may be caused. Disclosure of Invention The application provides a method, a device, equipment and a system for synchronizing signaling messages in a communication system, which are used for providing a scheme for synchronizing the signaling messages by a plurality of access points in the communication system, so that unnecessary competition and conflict can be reduced, and the waste of air interface resources is reduced. The technical scheme adopted is as follows: In a first aspect, the present application provides a method for synchronizing signaling messages in a communication system, where the communication system includes a master optical network unit and N slave optical network units, where N is a positive integer. The method comprises the steps that a master optical network unit sends networking information, wherein the networking information comprises indication information, and the indication information is used for indicating the sending time and the sending parameters of the N slave optical network units to send signaling messages. In the method, the control of the main optical network unit in the communication system can realize that a plurality of slave optical network units are synchronized to orderly send the signaling message according to the sending time and the sending parameter indicated by the main optical network unit. Compared with the mode that each slave optical network unit occupies air interface resources in a competing mode to transmit when transmitting signaling messages in each time in the related art, the method and the device can reduce unnecessary competition and conflict and reduce waste of air interface resources by synchronizing indication of the master optical network unit to the plurality of slave optical network units. In one possible manner, the communication system is a FTTR system. In one possible manner, the main optical network unit issues the indication message to the SFU in the FTTR network in advance of the Beacon period, that is, the main optical network unit issues the indication message to the SFU in the FTTR network before the Beacon period arrives, so as to instruct the SFU to send the Beacon frame according to the sending time and the corresponding sending parameters in the indication message. In one possible implementation manner, the master optical network unit sends the networking message, which includes that the master optical network uni
