Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a remote wake-up control method, device, electronic device, and storage medium. Background Art

[0002] Currently, host devices and USB slave devices (such as wireless communication modules) primarily communicate data and exchange commands over USB. The host device (also referred to as the host) controls the module's sleep and wakeup via the SUSPEND (suspend) and RESUME (resume a suspended process) signals specified in the USB protocol. When both the host device's USB and the wireless communication module's USB are in the SUSPEND state, if the wireless communication module has data to report to the host, the USB slave device must initiate a remote wakeup to wake the host, as per the USB specification.

[0003] The USB2.0 protocol specifies methods for enabling and disabling USB remote wakeup from a device: the host turns on remote wakeup from the USB device through SET_FEATURE(DEVICE_REMOTE_WAKEUP) and turns off remote wakeup from the USB device through CLEAR_FEATURE(DEVICE_REMOTE_WAKEUP).

[0004] Traditional USB devices are single-function devices, such as USB cameras, USB mass storage devices, USB mice and keyboards. However, with the development of wireless communication technology, USB composite devices are becoming increasingly popular. Current standard protocols cannot enable or disable the remote wakeup capability of a single interface on a composite USB slave device. For example, if the same USB slave device can simultaneously contain CDC-DATA (Communications Device Class - Data), mass storage devices, HID (Human Interface Device), AUDIO (Audio Device), and vendor-specific devices, the current USB 2.0 protocol is no longer able to provide more precise remote wakeup control.

[0053] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0055] In order to solve the technical problem of how to independently control the remote wake-up of a composite USB device interface in the prior art, the present application provides a remote wake-up control method, device, electronic device and storage medium, which can realize the remote wake-up of each interface of the composite USB device independently controlled, while also reducing the power consumption of the host.

[0056] The first embodiment of the present application provides a remote wake-up control method, which can be applied to Figure 1 The system architecture shown includes at least a host device 101 and a USB slave device 102, which establish a communication connection between the host device 101 and the USB slave device 102. The method can be applied to the host device 101 or the USB slave device 102 in the system architecture, wherein the USB slave device 102 can be a wireless communication module.

[0057] Next, based on the system architecture, the remote wake-up control method is described in detail. When applied to a host device, such as Figure 2 , the remote wake-up control method includes:

[0058] Step 201 , obtaining a remote wake-up requirement; wherein the remote wake-up requirement is used to indicate whether the target interface of the USB slave device is allowed to wake up the host device or whether the target interface of the USB slave device is prohibited to wake up the host device.

[0059] The remote wakeup requirement indicates the remote wakeup capability that the user wants the USB slave device to have. For example, the user only wants the audio interface in the wireless communication module to have remote wakeup capability, and other interfaces such as mass storage and HID cannot actively wake up the host. In this case, the remote wakeup requirement is: only the audio interface has remote wakeup function.

[0060] Step 202: Generate a control message based on the remote wakeup extension protocol and the remote wakeup requirement, and send the control message to the USB slave device to enable the USB slave device to wake up the host device through the target interface or prohibit the USB slave device from waking up the host device through the target interface.

[0061] The method can generate a control message according to the extended protocol of remote wake-up and the remote wake-up requirement, and send the control message to the USB slave device, so that the USB slave device wakes up the host device through the target interface or prohibits the USB slave device from waking up the host device through the target interface, thereby realizing independent control of the remote wake-up of each interface and reducing the power consumption of the host.

[0062] The extended protocol for remote wakeup can be pre-configured, so that when a remote wakeup request is obtained, a control message is directly generated based on the pre-configured extended protocol for remote wakeup, thereby improving the response speed. Of course, it can also be configured when there is a remote wakeup request, without restriction.

[0063] In one embodiment, the remote wakeup control method further includes: obtaining a protocol specification of a USB standard protocol; and configuring an extended protocol for remote wakeup based on the protocol specification.

[0064] In this embodiment, the extended protocol may be configured based on the protocol specification of the USB standard protocol, so that the customized extended protocol complies with the protocol specification of the USB standard protocol.

[0065] For example, the existing remote wakeup control protocols of the USB 2.0 protocol are as follows:

[0066] Table 1

[0067]

[0068] The USB control request message consists of the bmRequestType (request type), bRequest (request), wValue (value), wIndex (interface index), wLength (length), and Data (data) fields. When the bmRequestType field is 0x00 (00000000B) and the bRequest field is 0x03 (SET_FEATURE), it indicates that all interfaces of the USB slave device have remote wake-up capability. When the bmRequestType field is 0x40 (01000000B) and the bRequest field is 0x01 (CLEAR_FEATURE), it indicates that the remote wake-up capability of all interfaces of the USB slave device has been cleared.

[0069] In one embodiment, an extended protocol for remote wake-up is configured based on a protocol specification, including: configuring the request type bit in the request type field to be manufacturer-defined; configuring the receiver bit in the request type field to be an interface; and configuring the data transmission direction bit in the request type field to be from a host device to a USB slave device.

[0070] In this embodiment, when configuring the extended protocol, the request type configuration bit [D6:D5] in the bmRequestType field is configured to 2, indicating that it is customized by the vendor, the receiver bit [D4:D0] is configured to 1, indicating the interface, and the data transmission direction bit is configured to 0, indicating from the host device to the USB slave device (Host-to-device), so that the extended protocol complies with the protocol specifications of the standard protocol. When generating a control message based on the extended protocol, the corresponding interface index field can be configured with the interface identifier of the target interface, so that the USB slave device can wake up the host device through the target interface or prohibit the USB slave device from waking up the host device through the target interface.

[0071] In one embodiment, when the remote wake-up requirement is to allow the target interface of the USB slave device to wake up the host device, a control message is generated based on the remote wake-up extended protocol and the remote wake-up requirement, and the control message is sent to the USB slave device, including: configuring the interface identifier of the target interface in the interface index field based on the remote wake-up extended protocol; configuring the enable identifier in the first request field based on the extended protocol to obtain the control message; wherein the enable identifier is used to enable the remote wake-up function of the target interface of the interface index field; sending the control message to the USB slave device to allow the USB slave device to wake up the host device through the target interface, and prohibiting the host device from being woken up through other interfaces of the USB slave device.

[0072] In this embodiment, when the remote wake-up requirement is to allow the target interface of the USB slave device (also referred to as the USB slave) to wake up the host device, the remote wake-up control method is as follows: Figure 3 In the USB bus wake-up state, enable the USB slave interface N to initiate remote wake-up, configure the interface identifier of the target interface in the interface index field based on the extended protocol, such as configuring interface N in the wIndex field, and configuring 0x41 in the bmRequestType field. Configure the enable identifier in the first request field based on the extended protocol, such as configuring bRequest to 0x03, obtain a control message, and send the control message to the USB slave device. For example, the host sends a control message to the slave EP0, wherein bmRequestType=0x41, bRequest=0x03, wValue=0x01, wIndex=N, wLength=0x00, and other fields such as Data are 0x00, so as to allow the USB slave device to wake up the host device through the target interface, and prohibit waking up the host device through other interfaces of the USB slave device. At this time, only interface N of the USB slave device has the remote wake-up function.

[0073] In one embodiment, when the remote wake-up requirement is to prohibit the target interface of the USB slave device from waking up the host device, a control message is generated based on the remote wake-up extended protocol and the remote wake-up requirement, and the control message is sent to the USB slave device, including: configuring the interface identifier of the target interface in the interface index field based on the remote wake-up extended protocol; configuring a clear flag in the first request field based on the extended protocol to obtain a control message; wherein the clear flag is used to clear the remote wake-up function of the target interface of the interface index field; sending the control message to the USB slave device to prohibit the USB slave device from waking up the host device through the target interface, and to allow the host device to be woken up through other interfaces of the USB slave device.

[0074] In this embodiment, when the remote wake-up requirement is to prohibit the target interface of the USB slave device from waking up the host device, the remote wake-up control method is as follows: Figure 4In the USB bus wake-up state, clear the USB slave interface N to initiate remote wake-up, configure the interface identifier of the target interface in the interface index field based on the extended protocol, such as configuring interface N in the wIndex field, and configuring 0x41 in the bmRequestType field. Configure the clear flag in the first request field based on the extended protocol, such as configuring bRequest to 0x01, obtain the control message, and send the control message to the USB slave device. For example, the host sends a control message to the slave EP0, where bmRequestType=0x41, bRequest=0x01, wValue=0x01, wIndex=N, wLength=0x00, and other fields such as Data are 0x00, so as to prohibit the USB slave device from waking up the host device through the target interface and allow the host device to be woken up through other interfaces of the USB slave device. At this time, only interface N of the USB slave device does not have the remote wake-up function, and other interfaces can be remotely woken up.

[0075] In one embodiment, before configuring the interface identifier of the target interface in the interface index field based on the extended protocol for remote wake-up, the method also includes: sending a first control message to the USB slave device based on the USB standard protocol; wherein the first control message is used to enable all interfaces of the USB slave device to allow remote wake-up of the host device.

[0076] In this embodiment, since the extended protocol is the control of the interface and the USB2.0 standard protocol is the control of the device (i.e., the USB2.0 standard protocol controls all nodes of the USB slave device at the same time, and the extended protocol controls a certain interface of the USB slave device), the extended protocol can be used in addition to being used independently or in conjunction with the standard protocol. When the extended protocol and the standard protocol are used in combination, the remote wake-up control method is as follows: Figure 5In the USB bus wake-up state, the USB standard protocol is used to enable remote wake-up of the USB slave. For example, the host sends a control message to the slave EP0, where bmRequestType = 0x00, bRequest = 0x03, wValue = 0x01, wIndex = 0x00, wLength = 0x00, and other fields such as Data are 0x00. At this time, all interfaces of the USB slave have the remote wake-up capability. At this time, the ability of the USB slave interface N to initiate remote wake-up is cleared, and the interface identifier of the target interface is configured in the interface index field based on the extended protocol, such as configuring interface N in the wIndex field, and in the bmRequestType field. Configure 0x41 and configure the clear flag in the first request field based on the extended protocol. For example, configure bRequest to 0x01, that is, the host needs to send the following control message to the slave EP0: bmRequestType = 0x41, bRequest = 0x01, wValue = 0x01, wIndex = N, wLength = 0x00, and other fields such as Data are 0x00. The control message is sent to the USB slave device to prohibit the USB slave device from waking up the host device through the target interface, and to allow the host device to be woken up through other interfaces of the USB slave device. At this time, only interface N of the USB slave device does not have the remote wake-up function, and other interfaces can be remotely woken up.

[0077] In the above-mentioned embodiments of the present application, the USB 2.0 protocol cannot independently control the remote wakeup of each interface of the USB slave device. By extending the protocol, the remote wakeup of each interface can be independently controlled, achieving more flexible control and thus lowering the power consumption of the entire device. Moreover, the independent control of the remote wakeup of the USB slave device proposed in this application is fully compatible with the standard USB protocol, and can serve as a complement to each other.

[0078] When applied to USB slave devices, such as Figure 6 , the remote wake-up control method includes:

[0079] Step 601, obtain a control message sent by the host device; wherein the control message is generated based on a remote wakeup requirement and an extended protocol for remote wakeup; the remote wakeup requirement is used to indicate whether the target interface of the USB slave device is allowed to wake up the host device or whether the target interface of the USB slave device is prohibited from waking up the host device.

[0080] Step 602 : When the USB slave device has a data reporting requirement, the host device is awakened via the target interface based on a control message, or the host device is prohibited from being awakened via the target interface.

[0081] With this method, a USB slave device can obtain a control message generated by a host device based on a remote wake-up requirement and an extended protocol for remote wake-up. Thus, when the USB slave device has a data reporting requirement, the host device is awakened through a target interface based on the control message, or awakening the host device through the target interface is prohibited. This achieves independent control of remote wake-up of each interface of the USB slave device and can also reduce the power consumption of the host caused by frequent wake-up of the slave device.

[0082] In one embodiment, when the USB slave has only interface N but no remote wake-up function, the remote wake-up control method for the USB slave to wake up the host is as follows: Figure 7 In the USB bus sleep state, when the USB slave has data to report to the host, it can first determine whether it is the data of interface N. If it is the data of interface N, the USB slave does not initiate remote wake-up. If it is not the data of interface N, the USB slave can initiate USB remote wake-up.

[0083] Based on the same technical concept, the second embodiment of the present application provides a remote wake-up control device, which, when applied to a host device, Figure 8 , the device comprises:

[0084] The first acquisition module 801 is used to obtain a remote wake-up requirement; wherein the remote wake-up requirement is used to indicate whether the target interface of the USB slave device is allowed to wake up the host device or whether the target interface of the USB slave device is prohibited from waking up the host device;

[0085] The sending module 802 is used to generate a control message based on the extended protocol of remote wake-up and the remote wake-up requirement, and send the control message to the USB slave device to enable the USB slave device to wake up the host device through the target interface or prohibit the USB slave device from waking up the host device through the target interface.

[0086] The device can generate a control message according to the extended protocol of remote wake-up and the remote wake-up requirement, and send the control message to the USB slave device, so that the USB slave device wakes up the host device through the target interface or prohibits the USB slave device from waking up the host device through the target interface, thereby realizing independent control of the remote wake-up of each interface and reducing the power consumption of the host.

[0087] When applied to USB slave devices, such as Figure 9 , the device comprises:

[0088] A second acquisition module 901 is configured to acquire a control message sent by a host device; wherein the control message is generated based on a remote wakeup requirement and an extended protocol for remote wakeup; the remote wakeup requirement is used to indicate whether the target interface of the USB slave device is allowed to wake up the host device or whether the target interface of the USB slave device is prohibited from waking up the host device;

[0089] The control module 902 is configured to, when the USB slave device has a data reporting requirement, wake up the host device through the target interface based on the control message or prohibit waking up the host device through the target interface.

[0090] With this device, a USB slave device can obtain control messages generated by a host device based on remote wake-up requirements and an extended protocol for remote wake-up. Thus, when the USB slave device has a data reporting requirement, the host device can be woken up through a target interface based on the control message or be prohibited from waking up the host device through the target interface, thereby independently controlling the remote wake-up of each interface of the USB slave device and reducing the power consumption of the host caused by frequent wake-up of the slave device.
