Description

Energy-saving state control method, device, equipment, system and medium Technical Field The present application relates to the field of optical communications technologies, and in particular, to a method, an apparatus, a device, a system, and a medium for controlling an energy saving state. Background In an optical access network, the problem of power consumption of optical communication devices is receiving a great deal of attention. In the related art, some energy-saving management policies are formulated for ONUs in a PON (passive optical network, PON) system. In case the optical line terminal (optical LINE TERMINAL, OLT) allows the optical network unit (optical network unit, ONU) to enter the power saving state, if the ONU needs to enter the power saving state, a sleep request message is sent to the OLT to enter the power saving state. And in the energy-saving state, the ONU is circularly switched between an awake state and a low-power-consumption state, wherein in the low-power-consumption state, part of modules of the ONU are fixedly closed, and part of modules are periodically opened, so that the power consumption of the ONU is reduced. However, since the time at which each ONU enters the power saving state is different, the duration of the awake state and the duration of the low power consumption state may also be different, and thus the power saving states of the respective ONUs are unsynchronized. Disclosure of Invention The application provides a control method, a device, equipment, a system and a medium for energy-saving states, which can realize the synchronization of the energy-saving states of a plurality of ONUs. In a first aspect, the present application provides a method for controlling an energy saving state. The control method of the power saving state is performed by the OLT. The control method of the energy-saving state comprises the steps that an OLT determines that at least two ONUs in the energy-saving state exist in a plurality of ONUs connected with the OLT, and sends energy-saving indication information to the at least two ONUs in the energy-saving state, wherein the energy-saving indication information is used for indicating the ONUs to set the energy-saving state based on energy-saving configuration information, and the energy-saving configuration information comprises duration of a low-power-consumption state and duration of a wake-up state. In the application, after at least two ONUs in the energy-saving state receive the energy-saving indication message, the energy-saving state is set based on the energy-saving configuration information, so that the synchronization of the energy-saving states of the at least two ONUs can be realized. That is, the OLT may control at least some ONUs connected to the OLT to achieve synchronization of the power saving state through the power saving instruction message. Optionally, the power saving state of the ONU includes a low power consumption state and an awake state. In the low power consumption state, at least part of modules of the ONU are closed so as to reduce the power consumption of the ONU. When the ONU is in a low power consumption state, the OLT needs to store downlink data of the ONU, and the downlink data is sent to the ONU after the ONU enters an awake state. Therefore, when the duration of the low power consumption state is long and the energy saving states of the ONUs are not synchronous, if the downstream data of the ONUs need to be queued for transmission, the ONU corresponding to the downstream data received first cannot transmit because the ONU corresponding to the downstream data is in the low power consumption state, and therefore the downstream data received later cannot transmit to the corresponding ONU. The downstream data transmission of the ONUs is blocked, so that the OLT needs to store a large amount of data, and the OLT has a high requirement on the storage capacity. The application can send the downlink data of each ONU in the wake-up state by synchronizing the energy-saving states of the ONUs, thereby avoiding the situation of downlink data blocking and further reducing the requirement on the storage capacity of the OLT. Optionally, the energy saving indication message is a sleep permission message. The energy-saving indication message can be obtained by expanding the sleep permission message, and the existing message format is multiplexed, so that the realization is convenient. In some examples, the power saving indication message is used to force the ONU into a power saving state. Wherein, forcing the slave device into the power saving state means forcing the slave device to break the current state of the slave device and forcing the slave device into the power saving state, and when the plurality of slave devices each receive the power saving indication message, synchronization of the power saving states of the plurality of slave devices can be achieved. In a first possible implementation, each ONU needs to
