Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0023] The embodiments of the present application describe some exemplary embodiments for the purpose of explanation. It should be understood that the present application can be implemented in other ways that are not specifically shown in the drawings.

[0024] like Figure 1 As shown, an embodiment of the present application provides an optical network unit energy saving method, which can be applied to an optical network unit energy saving device. The optical network unit energy saving device can be an optical line terminal (Optical Line Terminal, OLT). The optical network unit energy saving method may include S101-S102: S101. An optical line terminal obtains interface data of an optical network unit group reported by a virtual optical network unit.

[0025] The above interface data includes the interface uplink traffic and the number of connected wireless users.

[0026] In the FTTR network, at least one OLT is included, and each OLT includes at least one virtual domain, that is, an OLT includes one or more virtual domains, and each virtual domain manages multiple ONUs. The present application can add multiple physical ONUs under a single user's home to a virtual optical network unit (Virtual Optical Network Unit, V-ONU) to form a logically integrated V-ONU, so that the OLT only needs to indirectly manage the optical network unit group composed of multiple physical ONUs through the V-ONU domain. The V-ONU can be used to monitor the interface data of the optical network unit group, and report it to the optical line terminal regularly. That is, the intra-domain performance statistics of the V-ONU include the interface upstream traffic of the ONU and the number of connected wireless users. The V-ONU can report the statistically obtained interface upstream traffic and the number of connected wireless users to the OLT regularly.

[0027] Optionally, before obtaining the interface data of the optical network unit group reported by the virtual optical network unit, the optical line terminal can create a virtual ONU, namely V-ONU, when creating the FTTR virtual domain. Specifically, the administrator can create a new V-ONU domain on the management interface of the OLT and add multiple physical ONUs to the virtual domain. The OLT can send default parameters to the V-ONU, and the V-ONU can configure default energy-saving parameters for the optical network unit group under the domain, and the energy saving is turned off by default.

[0028] S102: When the uplink traffic of the interface is less than a first threshold and the number of wireless users is 0, the optical line terminal sends an energy-saving instruction to the virtual optical network unit.

[0029] The energy-saving instruction is used to enable the virtual optical network unit to perform an energy-saving operation.

[0030] It should be noted that the state machine of the ONU interface includes two main states: Sleeping and Running. The sleeping state is the energy-saving state, and the running state is the normal operating state when no energy-saving operation is performed.

[0031] Optionally, the OLT can determine whether each interface of the ONU in the V-ONU meets the conditions of the sleep state or the running state based on the interface data obtained. When the interface upstream traffic is less than the first threshold and the number of wireless users is 0, it means that the sleep state condition is met, and the optical line terminal can send an energy-saving instruction to the virtual optical network unit, and the state machine of the interface can switch from the running state to the sleep state based on the control of the virtual optical network unit. When the interface upstream traffic is greater than or equal to the first threshold, or the number of wireless users is greater than 0, it means that the running state condition is met, and the optical line terminal can control all interfaces through the virtual optical network unit to maintain a normal working mechanism. Specifically, if it is currently in the running state, the interface state machine can continue to maintain the running state. If it is currently in the sleep state, the optical line terminal can send an instruction to the V-ONU to control the interface state machine of the physical ONU to switch from the sleep state to the running state.

[0032] It should be noted that the setting of the first threshold can be determined based on historical network traffic data and user behavior analysis. The monitoring of the number of wireless users can be achieved through the wireless management module of the ONU in the domain.

[0033] Optionally, the energy-saving operation includes turning off a tx signal of an Ethernet interface and reducing a transmission power of a wireless interface.

[0034] Specifically, after receiving the energy-saving instruction, the V-ONU can perform the following energy-saving operations on the interfaces within the domain: turn off the tx signal of the Ethernet interface; reduce the transmission power of the wireless interface. For example, if there are no connected users under the SSID, the transmission power can be reduced by 15%; if there are connected users under the SSID, the transmission power can be reduced by 30%.

[0035] Optionally, the steps of the wireless interface of the ONU entering a low power state include: the V-ONU domain sends a power reduction command to the physical ONU; evaluates the currently used wireless channels to determine whether it is necessary to shut down some channels to further save energy; and sends a low power state notification to user devices that may be affected, prompting them of possible connection interruption.

[0036] Optionally, in a low power state, the wireless interface can take the following measures: reduce the wireless transmission power to a predetermined low level, such as 15%, to reduce energy consumption; shut down non-critical channels to reduce radio frequency occupancy and interference; continue to monitor the wireless signal quality to ensure that basic service quality requirements are still met in a low power state.

[0037] Optionally, the wireless recovery mechanism of the ONU includes: identifying the activity status of the user equipment through the user equipment status monitoring system of the V-ONU domain; immediately adjusting the wireless transmission power to a normal level upon detecting a user equipment connection request or an increase in traffic; reactivating previously dormant channels to ensure the integrity and coverage of the wireless network; and the V-ONU continuously monitors the status of interfaces within the domain.

[0038] It should be noted that through the design of this state machine and energy-saving mechanism, this application achieves the following technical effects: By real-time monitoring and intelligent analysis of network traffic and user activities, it is possible to more accurately identify when energy-saving mode can be enabled, thereby reducing unnecessary energy consumption; Compared with traditional static threshold management, this application adopts a dynamic adjustment mechanism that can adjust the energy-saving strategy based on real-time data to adapt to changing network conditions; By intelligently identifying the usage of user-side interfaces, the allocation of network resources is optimized, ensuring sufficient bandwidth when user demand is high and reducing resource usage when demand is low; By ensuring rapid switching from energy-saving to normal working state when user activity increases, the negative impact on user experience is reduced, and service continuity and stability are maintained even during high traffic periods; Automated energy-saving controls reduce the need for manual adjustments to network equipment, thereby reducing maintenance costs and operational complexity; By reducing the operating time of equipment under high load, it helps to extend the service life of equipment, reduce failure rate and improve the reliability of the entire network; Provides flexible configuration options, allowing network administrators to adjust energy-saving parameters according to specific business needs and network policies; By integrating advanced data analysis and machine learning technologies, the network's intelligence level is improved, enabling it to autonomously learn and adapt to different network usage patterns; This application is suitable for large-scale FTTR network deployment, capable of handling hundreds or thousands of ONU devices while maintaining efficient energy-saving management; The energy-saving strategy of this application is based on real-time data and historical data analysis to ensure the accuracy and effectiveness of decision-making; As the number of users and business needs grow, this application can be easily expanded to accommodate larger network sizes without requiring large-scale modifications to existing systems.

[0039] In the embodiment of the present application, since the interface data of the optical network unit group can be determined through the virtual optical network unit, and an energy-saving instruction is sent to the virtual optical network unit when the interface upstream traffic is less than the first threshold and the number of wireless users is 0, it is possible to reduce unnecessary energy consumption and reduce overall electricity costs without affecting daily use; it is also possible to centrally manage multiple optical network units within the domain, reduce the complexity of configuring and managing each individual optical network unit, and improve the efficiency of network management.
