The method is simple and practical, and has high operability. Preferably, the network management system controls the network element to perform the corresponding power saving process according to the determined alarm type. The alarm system may notify the network element to start the power saving mode when the alarm type is an AC power failure alarm (for example, the network management system in the power saving mode) The N-band user port is set to a high-impedance state, and the broadband user port is periodically enabled and disabled or the fan speed of the network element is disabled. When the alarm type is one power-off alarm, the network management system sends the network management system to the network element. Indicates that the broadband function is disabled.

The receiving device 28 is coupled to the obtaining device 22 and configured to receive the energy information returned by the EPM device and the alarm information reported by the EPM device. Preferably, the power saving device 24 includes: a determining module 242, configured to determine, according to the energy information acquired by the obtaining device 22, whether the current battery capacity of the power source is lower than a preset threshold; and the closing module 244 is set to the current battery capacity of the power source.

Carry out the corresponding power saving process. The implementation process of the above embodiment will be described in detail below in conjunction with the preferred embodiments and the accompanying drawings. Embodiment 1 This embodiment provides a power saving method applied in an MS AG device, and uses an EPM device to monitor an intelligent power supply that supplies power to an MS AG device. The EPM device reports a power alarm at any time, and the network management system receives the EPM device. After reporting the related alarms, on the one hand, notify the relevant personnel to deal with the faults in time, and on the other hand, issue control commands to the network element (that is, the power supply network element of the intelligent power supply) to turn off some unimportant functions, thereby achieving the purpose of power saving. To save energy and reduce consumption, in the case of power outages, you can maximize the usage time of the network element system. In addition, the user can also view the analog voltage of the smart power source and the like from the EPM device by querying the command on the remote network management device at any time, thereby determining the margin of the smart power source, and remotely shutting down the network element when the smart power source is about to be emptied. Then, the network element stops the power consumption of the smart power source, and the smart power supply is prevented from being emptied and cannot be recharged. 4 is a schematic diagram of a network management system according to Embodiment 1 of the present invention. As shown in FIG. 4, the method for monitoring power supply of the network management system may include the following steps: Step 1: The EPM sends a query command to the intelligent power supply, and the intelligent power supply returns related information. Analog information and alarm information (ie, status information). Step 2: The network management system sends an inquiry analog command to the EPM through the network element, and the EPM returns the analog quantity information. At the same time, the EPM reports the alarm and alarm recovery at any time. It should be noted that although the data stream needs to be transmitted through the network element, the communication information of the network element before the network management and the EPM is actually transparently processed and is not parsed. The advantage of this approach is that there is no dependency between the EPM and the network element, which can enhance the scalability of the system. Step 3: When the network management system obtains some special alarms on the EPM or sees that the power battery capacity (for example, obtained by analog voltages such as voltage and current of the smart power source) is at a relatively low level, the control network element is correspondingly Power saving treatment. During the implementation process, the EPM can continuously send query commands to the monitored intelligent power supply in a cyclical manner, some of which obtain instant analog voltage information such as voltage and current of the intelligent power supply, and the EPM temporarily stores the analog information, when the network management system The reply is sent when the query command is issued. The other part of the command gets the alarm status of the smart power supply. When a new alarm occurs, the EPM immediately reports to the network management system and temporarily stores the current alarm. When the current temporary alarm disappears, the EPM immediately The message of the last 4 艮 alarm recovery is sent to the network management. It can be seen that the network management system in this embodiment can actively manage the power saving of the network element in the case of the power failure of the MSAG device, thereby improving the usage time of the network element as much as possible. The network management system in this embodiment can perform power saving processing according to the alarm information reported by the EPM device. For example, the alarm information can be classified into the following three types: AC power failure alarm, one power failure alarm, and secondary power failure alarm. The network management system can process different nodes for different alarm types. Specifically, it can be:

1 When the AC power failure alarm occurs on the EPM, the network management system automatically reports the network element to start the power-saving mode, but this stage still guarantees the normal operation of all services. The power saving operation performed by the network element includes: setting the unlabeled narrowband user port to a high impedance state, automatically detecting the user busy tone and entering the lockout state, automatically reducing the feed current, and periodically enabling and disabling the broadband user port. Operation to reduce power consumption, reduce power consumption by sacrificing a certain link-building time, and reduce the speed of the matching fan of the MS AG device.

2 When the EPM reports a power-off alarm, it indicates that the battery is running DC power after a period of AC power failure, and it still has not recovered. After receiving a power-off alarm, the NMS sends a command to the NE to disable the broadband function and retain only the narrowband function. This can extend the time that the network element provides voice services as much as possible while sacrificing the broadband function.

3 When the EPM reports a secondary power-off alarm, it indicates that the remaining battery capacity of the MS AG device is already very low, and can only support 4 艮 short time. After receiving the alarm of secondary power-off, the NMS remotely shuts down the NE to prevent the battery from being emptied. Since there are many kinds of communication protocols for intelligent power supplies, not all power supplies support reporting all three types of alarms. Therefore, EPM provides a supplementary processing method, that is, active management based on the queried battery capacity, and specific management. The way of the network element is the same as the above method. Preferably, the AC power supply part of some small devices may not use the smart power supply, but the power supply battery may be directly monitored by the EPM module of the network element, and other processing methods are similar. It should be noted that, although the embodiment of the present invention is based on the MSAG device in the fixed network access network, the network management system in the embodiment of the present invention monitors the power supply scheme because there is no dependency between the EPM device and the network element. It is not limited to the fixed network access network and can be extended to other communication systems. In summary, the network management system in this embodiment can perform reverse control according to the result of power monitoring (that is, power saving the network element), thereby saving energy and reducing consumption, and prolonging the use time of the power supply. Obviously, those skilled in the art should understand that the above modules or steps of the present invention can be implemented by a general-purpose computing device, which can be concentrated on a single computing device or distributed over a network composed of multiple computing devices. Alternatively, they may be implemented by program code executable by the computing device so that they may be stored in the storage device by the computing device, or they may be separately fabricated into individual integrated circuit modules, or Multiple modules or steps are made into a single integrated circuit module. Thus, the invention is not limited to any specific combination of hardware and software. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the scope of the present invention are intended to be included within the scope of the present invention.
