Description

Energy-saving control method, device and system applied to FTTR Technical Field The present application relates to the field of communications, and in particular, to an energy saving control method, device and system applied to FTTR. Background With the development of communication technology, optical fiber transmission is increasingly being used in communication systems, where optical fiber to the room (fiber to the room, FTTR) is an important ring in optical networks. The FTTR system comprises a main device (MAIN DEVICE) and a sub device (sub device), wherein the main device is connected with the sub device through an optical fiber. The master device is an optical network terminal (optical network terminal, ONT), also called an optical network unit (optical network unit, ONU), in a passive optical network (passive optical network, PON) and is connected to an optical line terminal (optical LINE TERMINAL, OLT) at the operator's office by an optical fiber. In FTTR systems, there are usually multiple sub-devices, if all the sub-devices keep normal working state all the time, the overall power consumption will be larger, in practical application, the middle part of the sub-devices may be switched to the energy-saving working state in some time periods, and the overall operation of FTTR systems will not be affected. Therefore, a need exists for a way in which a master device can reasonably schedule multiple sub-devices in a power saving manner. Disclosure of Invention The embodiment of the application provides an energy-saving control method, device and system applied to a fiber-to-room (fiber to the room, FTTR). The main device can know whether each sub-device can start the energy-saving characteristic and the energy-saving capability of the sub-device with the energy-saving characteristic, and the main device can reasonably and energy-saving schedule the plurality of sub-devices according to the known information, so that the energy-saving effect can be better optimized. In a first aspect, embodiments of the present application provide a power saving control method applied to FTTR, where the master device is also referred to as a master FTTR device (Main FTTR Unit, MFU) in the FTTR system, and the slave device is also referred to as a slave FTTR device (Sub FTTR Unit, SFU) in the FTTR system. The energy-saving control method is applied to the main equipment, and specifically, the main equipment sends a first message to the first sub-equipment, wherein the first message is used for indicating the first sub-equipment to start the energy-saving characteristic. The first sub-device confirms to start the energy-saving characteristic according to the first message, and the first sub-device is used for supporting to switch to the energy-saving state, which is equivalent to supporting energy-saving scheduling of the main device. The first sub-device may acquire the power saving capability after confirming that the power saving feature is turned on. Further, the master device receives a second message sent by the first sub-device, the second message including the power saving capabilities of the first sub-device. In this embodiment, since the master device can know whether each sub-device can turn on the energy-saving characteristic and the energy-saving capability of the sub-device capable of turning on the energy-saving characteristic, the master device can reasonably perform energy-saving scheduling on the plurality of sub-devices according to the known information, so that the energy-saving effect can be better optimized. Particularly, in the FTTR system, a plurality of pieces of sub-equipment are deployed in each room of a home or office area to provide signals for the user terminal, and the characteristics that the main equipment can cooperatively manage the plurality of pieces of sub-equipment are utilized, so that better energy-saving effect can be provided for the scenes of the home or office area in the mode. In some possible implementations, after the master device sends the first message to the first sub-device, the method further includes the master device receiving a third message sent by the first sub-device, the third message being used to instruct the first sub-device to confirm that the energy saving feature is turned on. That is, the third message may be regarded as an Acknowledgement (ACK) message of the first message, so that the master device knows that the first sub-device has acknowledged the power saving feature to enable the master device to perform power saving scheduling on the first sub-device in a targeted manner. In some possible implementations, before the master device sends the first message to the first sub-device, the method further includes the master device sending a fourth message to the first sub-device to enable the first sub-device to perform energy saving configuration according to configuration parameters in the fourth message. The configuration parameters can be updated to
