It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a flowchart of a first embodiment of a method for controlling a dormancy of a virtual desktop according to the present invention. The method is applied to a virtual desktop system including a server and a client, where the server runs a virtual machine connected to the client. As shown in FIG. 1, the method in this embodiment may include:

Step 101: The server receives a sleep request message sent by the client.

The server runs a virtual machine allocated to the client, and the server provides a virtual desktop service carrier. The user's desktop system (Virtual Desktop) exists in the form of a virtual machine (VM). On the server side. The client of the virtual desktop is usually called a thin client (TC), which is also called a thin terminal. The client can be in the form of a general computer, a tablet, a smart phone, etc., and the client can be connected with a display. Or an output device such as a display, and any one or more input devices such as a keyboard, a mouse, or a touch screen. The client may perform data communication with the server of the virtual machine that provides the client in the server group through the access gateway. The sleep request message may be hibernation request information sent to the server when the client detects that the input device of the client does not input the operation exceeds a preset sleep threshold. Optionally, the dormancy request message may include an identifier of the client.

Optionally, before the server device receives the sleep request message sent by the client, the server may further include:

Optionally, the server may send the dormancy threshold request message of the client to the management system to obtain a dormancy threshold of the client. The management system may be a background management system of the server. Optionally, the maintenance threshold of the client may be set by the maintenance personnel of the management system on the management system.

Optionally, the server may not send the set sleep threshold of the client to the client, where the configured sleep threshold of the client may be set by the client.

Step 102: The server determines, according to the sleep request message, whether an application of an operation-free class is run on a virtual machine connected to the client, where the application of the operation-free type refers to that the client is not required. The input device of the input device for input operations.

The application of the operation-free type may be an application such as a video player or a conference program, and the applications are prone to use for a period of time without requiring the user to input through the input device. The server may query, according to the identifier information of the client included in the sleep request message, the program information running on the virtual machine connected to the client, and then determine whether the virtual machine connected to the client is running. The application of the operation class, for example, the program name or process name of the application of the operation-free class.

Step 103: If it is determined that the application of the operation-free class is not running on the virtual machine of the client, the server sends an allow sleep indication to the client to indicate that the client enters a sleep state.

The server sends an allowable sleep indication to the client to indicate that the client enters a dormant state, which may specifically include:

Sending, by the server, an allowable sleep indication to the client, to indicate that the operating system of the client enters a sleep state, and/or,

The server sends an allowable sleep indication to the client to indicate that the display of the client enters a sleep state.

Step 104: If it is determined that the application of the operation-free class is running on the virtual machine of the client, the server sends a disable sleep indication to the client to instruct the client to prohibit entering the sleep state.

The server sends a forbidden sleep indication to the client, to indicate that the client is prohibited from entering the sleep state, and may specifically include:

Sending, by the server, an allowable sleep indication to the client, to indicate that the operating system of the client is prohibited from entering a sleep state, and/or,

The server sends an allowable sleep indication to the client to indicate that the display of the client is prohibited from entering a sleep state.

In this embodiment, the server receives the sleep request message sent by the client, and the server determines whether the virtual machine connected to the client runs the application of the operation-free class, and if the application of the operation-free class is not running, the sleep is allowed to be sent. The indication is to indicate that the client enters hibernation, and if the application with the operation-free class is running, a disable sleep indication is sent to indicate that the client is prohibited from entering hibernation, and the client is prevented from being positive. After running the software that does not need to input the operation for a period of time, the client sets the display to sleep and affects the user to use the virtual desktop service, and if the user does not run the operation-free software on the client and leaves for a long time without input operation, the client can Going to sleep saves power and reduces the loss of display life.

Further, if it is determined that the virtual machine of the client is not running the application of the operation-free class, the server sends the permission to sleep indication to the client to indicate that the client enters the sleep state, and further includes:

The image data is real-time display information of the user's desktop system, and the server converts the real-time display information of the user's desktop system into image data and sends it to the client through the remote desktop protocol. After the server device sends a display sleep response message to the client, the server may stop sending data to the client to save software resources and hardware resources on the server.

Optionally, if it is determined that the virtual machine of the client is not running an application of the operation-free class, the server sends an allowable sleep indication to the client, to indicate that the client enters a sleep state, and further includes:

The server receives the wakeup message sent by the client;

The wake-up message sent by the client is sent when the client detects that an input device such as a keyboard or a mouse has an input operation, or is sent according to a wake-up condition set by the client itself.

For example, after the client controls the client to enter the sleep state according to the allowable sleep indication, the client may continue to detect whether an input device such as a keyboard and a mouse acquires an input operation, and if the input operation is obtained, the client may The server sends a wake-up message.

Optionally, the client may further set a wakeup condition, such as a timed wakeup, and the client may wake up the client's own software to send the wakeup message to the server when the wakeup condition of the timed wakeup arrives. .

After receiving the wake-up message sent by the client, the server may resume sending data to the client, so that the client can restore the display of the user's desktop in time according to the needs of the user.

2 is a flowchart of a second embodiment of a method for controlling a dormancy of a virtual desktop according to the present invention. The method is applied to a virtual desktop system including a server and a client, where the server is connected to the client. The virtual machine, as shown in FIG. 2, the method in this embodiment may include:

Step 201: The client monitors its own input device.

Step 202: The client sends a sleep request message to the server when it detects that the input device does not input the operation for more than a preset sleep threshold.

When the input device of the client does not receive an input operation for a period of time, the client should determine whether to set the display to sleep to save power and reduce unnecessary loss of the device. The client can connect an input device such as a keyboard, a mouse, a touch screen, etc. to obtain an input operation of the user. The sleep threshold may be a time period in which one of the detection input devices set on the client has no input operation. Optionally, if it is detected that the user performs an input operation through any input device within a time period corresponding to the sleep threshold, the client may restart the timer of the sleep threshold. When the client detects that the input device has no input operation for more than a preset sleep threshold, the client may send a sleep request message to the server.

Step 203: When the client receives the allowable sleep indication sent by the server, the client controls the client to enter a sleep state.

The allowed sleep indication is sent after the server receives the sleep request message according to the sleep request message, and determines that the application of the operation-free type is not running on the virtual machine of the client. The application of the operation-free type may be an application such as a video player or a conference program, and such an application is prone to a period of time during which the user does not need to perform an input operation. The server may determine whether the operation-free software is running according to the program information running on the virtual machine corresponding to the client. For example, the server may determine whether the virtual operation on the virtual machine connected to the client is running. The program name or process name of the class application.

Optionally, the controlling the client to enter a sleep state may include controlling an operating system of the client to enter a sleep state, and/or controlling a display of the client to enter a sleep state. Step 204: The client controls the client to prohibit entering the sleep state when receiving the prohibition of sleeping indication sent by the server.

The forbidden sleep indication is sent after the server receives the sleep request message according to the sleep request message, and determines that the application of the operation-free type is run on the virtual machine of the client.

Optionally, the controlling the client to prohibit entering the sleep state may include controlling the operating system of the client to prohibit entering the sleep state, and/or controlling the display of the client to prohibit entering the sleep state.

For example, if the client receives the allowable sleep indication, that is, the server determines that the operation-free application is not running on the virtual machine of the client, and the client enters the sleep state does not affect the user. Normal use; if the client receives the prohibition of sleep indication, that means the server determines that the operation-free software is running on the virtual machine of the client, the client should not enter a sleep state, the client The client should be allowed to continue to work when it receives a disable sleep indication.

In this embodiment, the client monitors its own input device, and when it detects that the input device has no input operation for more than a preset sleep threshold, sends a sleep request message to the server, and receives the permission sent by the server. The sleep indication or the prohibition of the sleep indication, the client controls the client to enter a sleep state according to the permission to sleep indication, or control the client to prohibit entering the sleep state according to the prohibition of the sleep indication. Avoiding the application running on the client without user input operation for a period of time, the client sets the display to sleep and affects the user to use the virtual desktop service, and if the application of the operation-free class is not running on the client for a long time When leaving no input operation, the client can set the client to sleep, which saves power and reduces the unnecessary loss of display life. Optionally, before the client monitors its input device, the method further includes:

The client acquires a preset sleep threshold from the server.

Optionally, the client may also set the sleep threshold information of the client locally.

Optionally, the client in the embodiment of the present invention may pre-shutdown the sleep processing setting of the power management module of the operating system of the client; or

After the client receives the forbidden sleep indication sent by the server, the method further includes:

The sleep management process of the power management module to the client may be to set the client to go to sleep or set the display of the client to go to sleep.

For example, if the client pre-shuts the sleep processing setting of the power management module of the operating system of the client, the client determines whether to control the client to enter the sleep state according to the sleep threshold, and does not need to pay attention to the operation. Corresponding processing of power management on the system; if the client does not pre-set the sleep processing setting of the power management module of the operating system itself of the client, the client may monitor the sleep processing on the operating system, if The power management module of the operating system is to set the client to enter a sleep state, and the client may disable the sleep processing of the power management module of the operating system of the client.

Optionally, if the client receives the allowed sleep indication sent by the server, the indication After the client enters the hibernation state, the method further includes:

The sending, by the client, the wake-up message to the server is sent when the client detects a keyboard or mouse operation. Optionally, the client may further set a wake-up condition, such as a timed wake-up, and the client may wake up the client's own software when the wake-up condition of the timed wake-up arrives, and send the wake-up message to the server.

In the embodiment of the present invention, the client sends a wake-up message to the server to enable the server to resume sending image data to the client, so that when the user needs to use the client, the user desktop display can be promptly replied.
