The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The present invention provides a remote wake-up method. Referring to FIG. 1, in an embodiment, the method includes: Step S101: Receive device information reported by a client terminal of each network segment, and determine, according to the device information, the client terminal In the present embodiment, the customer premise equipment (CPE) may be on the same network segment or on different network segments. Each network segment has multiple client terminals, and the server may be a network segment. Or multiple network segment services. The server receives the device information reported by the client terminal of each network segment, and the server may be an automatic configuration server (ACS). The server communicates with the client terminal through a network management protocol, and thus is not limited by the local area network or the network structure. The device information includes: registration information, status information, and type information and IP information of the client terminal. If the registration information is valid registration information, it may be determined that the current status of the corresponding client terminal is an online status. If the registration information is invalid registration information, the current status of the corresponding client terminal is an offline status. The status information also indicates the current status of the client terminal, which includes offline information, upgrade information, or shutdown information, in addition to online information or standby information. When the status information is online information, the current status of the corresponding client terminal is online; when the status information is standby information, the current status of the corresponding client terminal is the standby status. In this embodiment, the server and the client terminal can be mutually agreed, and the server sends a management policy to the client terminal, and when the client terminal executes the management policy, the state information of the change is reported to the server; or, on the client terminal, the user Performing standby, online or shutdown, etc., and the client terminal actively reports the status information of the change to the server; or, if the client terminal initiates registration with the server, and the registration information is valid, the current state of the client terminal is online, at this time, The client terminal also actively reports its status information to the server; or, the client terminal changes from the standby state to the online state during the last remote wake-up process. At this time, the client terminal also actively reports its status information to the client terminal. server. Step S102: When it is confirmed that the network segment where the client terminal in the standby state is located has a client terminal in an online state, send a wake-up command to the client terminal in the online state, so that the client terminal in the online state wakes up the client in the standby state by using a wake-up command. terminal. In this embodiment, the client terminal in the standby state is the client terminal to be woken up. If a client terminal in the online state and a client terminal in the standby state exist in a certain network segment, the client terminal in the standby state can be awake through the client terminal in the online state, that is, the client terminal in the online state is used as a relay to wake up the standby state. Client terminal. In a specific implementation process, the server may send a wake-up command to the client terminal of the online state of a certain network segment, and after receiving the wake-up command, the client terminal in the online state constructs a magic packet according to the wake-up instruction, and performs on the network segment. The broadcaster wakes up the client terminal in the standby state, and the client terminal in the standby state becomes the client terminal in the online state. Compared with the prior art, in this embodiment, the client terminal of each network segment reports its current state, and the server determines whether the current state of the client terminal is online or offline, if online exists in a certain network segment. When the client terminal in the state and the client terminal in the standby state, the server can send a wake-up command to the client terminal in the online state, and the client terminal in the online state wakes up the client terminal in the standby state, and the server and the client terminal in this embodiment pass through the network. Management protocol to communicate, the server does not need to be in the LAN, because Therefore, it is not limited by the local area network or the network structure, and can realize remote wake-up across the network segment.
