Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

Referring to FIG. 1, the illustrated system for remotely awakening network user devices according to the new embodiment of the present invention is suitable for a plurality of user devices 4, 4'that operate in a sleep mode for energy saving in a local area network, 4". For convenience of explanation, the user devices 4, 4', 4" in this embodiment are, for example, via a router 3 connected between the local area network and a wide area network (eg, the Internet) Send and receive data, but not limited to this. However, in practical applications, the system can provide remote wake-up services for user devices (not shown) in multiple different regional network domains. For example, if the local network is an internal network in an enterprise, the user devices 4, 4', 4" may be computer devices configured in the enterprise, or if the local network is a smart home In the internal network of the system, each user device 4/4'/4" can be a smart home appliance device or a computer device configured in the smart home system. The system includes, for example, a management server 1 and a wake-up server 2.

It should be particularly noted that, for convenience of description, in the present embodiment, each of the management server 1 and the wake-up server 2 is implemented as a single computer device, but not limited thereto. However, in other implementations, the management server 1 and/or the wake-up server 2 can also be implemented as a computer system with a cluster structure.

The management server 1 includes, for example, a first communication module 11 connected to the wide area network, a first storage module 12, and a first electrically connected to the first communication module 11 and the first storage module 12 Processing module 13, but not limited to this. The first storage module 12 (which can be implemented as a database, for example, but not limited to this), during the registration phase of the user devices 4, 4', 4", a plurality of pens corresponding to the user devices are stored 4, 4', 4" device management information. Each piece of device management information is related to a corresponding user device 4/4'/4", and as shown in FIG. 2, for example, contains a device identification code that uniquely represents the corresponding user device 4/4'/4" A wake-up key assigned to the corresponding user device 4/4'/4" and the latest sleep login time (it can be a preset time before starting to use).

On the other hand, in the registration stage, for each user device 4/4'/4", the first processing module 13 of the management server 1 sends the assignment to the first communication module 12 and the router 3 to The wake-up key of the user device 4/4'/4" and the connection data related to the wake-up server 2 for the user device 4/4'/4" to store the wake-up key and the connection data ( (See FIG. 1) and connect to the wake-up server 2 according to the stored connection data in later use. It should be noted that, in this embodiment, since the wake-up server 2 is a single computer device, it is stored in each The connection data of the user device 4/4'/4" includes, for example, the connection URL (ie, IP address) of the wake-up server 2 on the wide area network. If the wake-up server 2 is a computer system with a cluster structure, the link data stored in each user device 4/4′/4” includes not only the wake-up server 2 (ie, the computer system) The link URL in the WAN, and contains the port number used to connect to a computer host (ie, a computer device in the computer system) responsible for serving the user device 4/4'/4” in the wake-up server 2 . In this way, when in use, the router 3 can use the connection data stored in each user device 4/4'/4" to establish a connection with the wake-up server 2 for data transmission. Incidentally, each User device 4/4'/4" can receive the link URL of the wake-up server 2 from the management server 1 and all computer hosts which are relatively close to the user device 4/4'/4" during the registration phase The port number of one or more computer hosts, and a computer host with the shortest response time is determined as the computer host serving the user device 4/4'/4” based on the response test. .

In addition, at the registration stage, the management server 1 has a wake-up right for at least one of the user devices 4, 4', 4", and the user terminal used by each registered user (for example, the user terminal shown in FIG. 1 5), send a user device list, which contains a device identification code representing the at least one user device 4/4'/4" and a wake-up key assigned to the at least one user device for the user terminal to store the user Device list.

In this embodiment, the wake-up server 2 includes, for example, a second communication module 21 connected to the wide area network, a second storage module 22, and electrically connecting the second communication module 21 and the second storage module The second processing module 23 of the group 22. In use, the second storage module 22 (which can be implemented as a database, but not limited to this) is used to store one or more pens corresponding to one of the user devices 4, 4', 4" Or multiple sleep records of user devices 4/4'/4" previously operating in the sleep mode. As shown in FIG. 3, each sleep record includes the device identification code representing the corresponding (operating in the sleep mode) the user device 4/4'/4" and assigned to the corresponding user device 4/4'/ The wake-up key of 4", the corresponding connection data of the user device 4/4'/4", and the latest sleep login time, wherein the connection data includes a connection URL of the router 3 in the wide area network, and the router 3 is used to connect the corresponding port number of the user device 4/4'/4".

In particular, each sleep record stored in the second storage module 22 is obtained by executing a management process. In this embodiment, a specific network card (not shown) installed on each user device 4/4'/4" enters sleep mode from the working mode on the user device 4/4'/4", or on the user The device 4/4'/4" continues to operate. When the sleep mode reaches a predetermined time (for example, 15 seconds), a sleep packet is sent to the wake-up server 2 via the router 3. The sleep packet includes, for example, The device identification code of the user device 4/4'/4", the wake-up key stored in the user device 4/4'/4", and the specific network card installed on the user device 4/4'/4" Provided link data, where the link data includes a link URL (ie, IP address) of the router 3 in the wide area network, and a port number for the router 3 to connect to the user device 4/4'/4" .

Hereinafter, referring to FIG. 1 and FIG. 4, an exemplary description will be given of how this embodiment performs the management procedure related to a user device operating in a sleep mode, such as the user device 4'. In this case, the user device 4'sends a sleep packet to the wake-up server 2 via the router 3. The management program includes the following steps S41 to S46.

When the second processing module 23 of the wake-up server 2 receives the sleep packet from the user device 4'via the second communication module 31 (step S41), the second processing module 23 according to the sleep The device identification code contained in the packet determines whether there is a sleep record corresponding to the user device 4'in the sleep record(s) stored by the second storage module 22 (step S42). When the judgment result is negative, the second processing module 23 stores a newly added sleep record corresponding to the user device 4'in the second storage module according to the sleep packet and the reception time of the sleep packet 22. The newly added sleep record includes the device identification code, the wake-up password and the connection data contained in the sleep packet, and the reception time of the sleep packet as the latest sleep registration time (step S43). When the determination result is affirmative, the second processing module 23 updates the latest sleep login time included in the sleep record corresponding to the user device 4'stored in the second storage module 22 to the received time ( Step S44). Following in step S45 following step S43 and step S44, the second processing module 23 sends a sleep notification including the reception time and the device identification code and the wake-up key contained in the sleep packet to the management server器1.

Then, in step S46, when the first processing module 13 of the management server 1 receives the sleep notification from the wake-up server 2 through the first communication module 11 group, the first processing module 13 In response to the sleep notification, one of the pen device management information stored in the first storage module 12 contains device management information of the device identification code and the wake-up key contained in the sleep notification (ie, corresponding to the The latest sleep registration time included in the device management information of the user device 4'is updated to the received time included in the sleep notification. So far, the management program for the user device 4'has been executed.

Hereinafter, referring to FIG. 1 and FIG. 5, an example will be described to illustrate how when a registered user wants to wake up a user device to be awakened remotely, for example, the user device 4 ″, this embodiment performs a remote wakeup on the user device 4 ″ program. In this case, the registered user can use a usage terminal 5 (for example, a mobile device), and after appropriate operations, for example, execute an application pre-installed on the usage terminal 5 and related to the remote wake-up service A program (which can be provided by an organization that sets up the system, but not limited thereto), so that the user terminal 5 sends a wake-up request to the management server 1 via the wide area network. In this embodiment, the wake-up request includes, for example, a device identification code representing the user device 4" and a wake-up key assigned to the user device 4". The remote wake-up procedure includes the following steps S51-S57.

First, in step S51, the first processing module 13 of the management server 1 receives the wake-up request related to the user device 4" from the user terminal 5 via the first communication module 11.

Then, in step S52, after authenticating the identity of the registered user, the first processing module 13 contains one of the pen device management information stored in the first storage module 12 according to the reception time of the wake-up request and The device identification code and the device management information of the wake-up key included in the wake-up request (ie, device management information corresponding to the user device 4") determine whether the user device 4" is operating in the sleep mode. In this embodiment, the first processing module 13 determines the time between the latest sleep registration time and the reception time of the wake-up request contained in the pen device management information stored by the first storage module 12 Whether the period is not longer than a predetermined time period (for example, but not limited to 15 seconds) to determine whether the user device to be woken up is operating in the sleep mode. More specifically, if the first processing module 13 determines that the time period is not longer than the predetermined time period, it determines that the user device 4" is operating in the sleep mode (ie, the determination result of step S52 is affirmative) and The process proceeds to step S53. On the contrary, if the first processing module 13 determines that the time period is longer than the predetermined time period, it determines that the user device 4" is not operating in the sleep mode (ie, the determination result of step S52 is No) and the flow proceeds to step S54.

In step S53, the first processing module 13 of the management server 1 uses the first communication module 11 to convert a reception time including the wake-up request, and the device identification code and the device identification code included in the wake-up request. The wake-up notification of the wake-up key is transmitted to the wake-up server.

In step S54, the first processing module 13 of the management server 1 sends a reply indicating that the user device 4" has been woken up to the user terminal 5 through the first communication module 11.

Following step S53 following step S53, when the second processing module 23 of the wake-up server 2 receives the wake-up notification from the management server 1 via the second communication module 21, the second processing The module 23 according to the reception time included in the wake-up notification and all the pen sleep records stored in the second storage module 22, one of which contains the device identification code and the wake-up key included in the wake-up notification and serves as the target sleep The recorded sleep record determines whether the user device 4" is operating in the sleep mode. In this embodiment, similar to the determination method of the first processing module 13 in step S52, the second processing module 23 determines by Whether the time period between the latest sleep login time included in the target sleep record stored in the second storage module 22 and the reception time included in the wake-up notification is not longer than the predetermined time period to determine the user device 4" Whether to operate in this sleep mode. More specifically, if the second processing module 23 determines that the time period is not longer than the predetermined time period, it is determined that the user device 4" is operating in the sleep mode (ie, the determination result of step S55 is affirmative) and The process proceeds to step S56. Conversely, if the second processing module 23 determines that the time period is longer than the predetermined time period, it determines that the user device 4" is not operating in the sleep mode (ie, the determination result of step S55 No) and the flow proceeds to step S57.

In step S56, the second processing module 23 of the wake-up server 2 uses the second communication module 21 to notify the wake-up key contained in the wake-up key according to the connection data included in the target sleep record And a wake-up command is sent to the user device 4". Then, the flow proceeds to step S57. In particular, the second processing module 23 causes the second communication module 21 to first according to the link contained in the link data The web address establishes a connection between the wide area network and the router 3, and then transmits the port number included in the connection data, the wake-up key and the wake-up command included in the wake-up notification to the second communication module 21 to the The router 3, so that the router 3 transmits the wake-up key and the wake-up command received from the wake-up server 2 to the user device 4" according to the port number. Therefore, after successfully confirming the wake-up key, the user device 4" receives the wake-up instruction and is woken up.

Finally, in step S57, the second processing module 23 of the wake-up server 2 deletes the target sleep record from the second storage module 22. In other words, when the wake-up server 2 determines that the user device 4" is not operating in sleep mode or sends the wake-up key and the wake-up command for waking up the user device 4", it means that the user device 4" has Being woken up or to be woken up, in this case, the wake-up server 2 no longer needs to keep the target sleep record, thereby effectively maintaining and managing the sleep record of each user device that is indeed operating in the sleep mode. , The remote wakeup sequence is completed.

In summary, since the management server 1 effectively stores and manages device management information corresponding to all user devices 4, 4', 4" and the wake-up server 2 effectively stores and manages and operates each in sleep mode A user device's 4/4'/4" related sleep records, so when a registered user who has been granted the right to wake up wants to wake up a user device 4/4'/4", the user terminal used by the registered user When the management server 1 sends a wake-up request containing a device identification code representing the user device 4/4'/4" and a wake-up key assigned to the user device 4/4'/4", the management server 1 and the wake-up server 2 both determine that the user device is operating in the sleep mode, the wake-up server 2 sends the wake-up key and wake-up command to the user device 4/4'/4 via the wide area network In order to achieve the purpose of effective and safe remote wakeup through the wide area network. Therefore, it can really achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
