Some concepts related to the present application will be described first.

The terms "first," "second," and the like in the embodiments of the present application are used for the purpose of distinguishing between similar features and not necessarily for the purpose of indicating a relative importance, quantity, order, or the like.

The terms "exemplary" or "such as" and the like, as used in connection with embodiments of the present application, are intended to be exemplary, or descriptive. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The terms "coupled" and "connected" in connection with embodiments of the present application are to be construed broadly, and may refer, for example, to a physical direct connection, or to an indirect connection via electronic devices, such as, for example, a connection via electrical resistance, inductance, capacitance, or other electronic devices.

At present, the electronic equipment is generally provided with a USB interface, the USB interface can be used as a data transmission interface, the USB interfaces of the two electronic equipment are connected through a USB cable, and wired data transmission between the two electronic equipment can be realized. However, setting the USB interface may affect the waterproof performance, the dustproof performance and the plugging life of the electronic device, and may also occupy the motherboard space, which is not beneficial to the ultrathin electronic device, so canceling the USB interface is a trend of developing the current electronic device.

If the USB interface is canceled, the data transmission function of the electronic equipment is required to be realized in a wireless data communication mode. In the prior art, when two electronic devices perform wireless data communication, the two electronic devices are required to be installed with an adaptive application program or driver in advance and then connected manually by a user.

To this end, as shown in fig. 1, the embodiment of the present application provides a communication conversion system including a first electronic device 20, a second electronic device 30, and a communication conversion apparatus 10. The first electronic device 20 is an electronic device that cancels the USB interface. The second electronic device 30 is a device that performs data transmission with the first electronic device 20. The communication conversion apparatus 10 is configured to establish a wireless communication connection with the first electronic device 20 and a USB communication connection with the second electronic device 30.

The first electronic device 20 may act as a slave to USB communication and the second electronic device 30 as a master to USB communication. For example, the first electronic device 20 is a mobile phone, a tablet, a smart watch, etc., and the second electronic device 30 is a personal computer (PC device), a notebook computer, etc. Alternatively, the first electronic device 20 may be a master device for USB communication, and the second electronic device 30 may be a slave device (or OTG device) for USB communication. For example, the first electronic device 20 is a mobile phone, a tablet, a smart watch, etc., and the second electronic device 30 is a USB disk, a USB mouse, a USB keyboard, a U shield, etc.

When the first electronic device 20 is used as a slave device of USB communication and the second electronic device 30 is used as a master device of USB communication, the communication conversion device 10 notifies the second electronic device 30 to perform enumeration, and during the enumeration process, the communication conversion device 10 is responsible for communication between the first electronic device 20 and the second electronic device 30. For example, the communication conversion apparatus 10 acquires USB device type information of the first electronic device 20 from the first electronic device 20 through a wireless communication connection, and transmits to the second electronic device 30 through a USB communication connection. At this time, the communication conversion apparatus 10 is mapped to the USB device indicated by the USB device type information, and is responsible for data communication between the first electronic device 20 and the second electronic device 30.

When the first electronic device 20 is used as a master device for USB communication and the second electronic device 30 is used as a slave device for USB communication, the communication conversion device 10 notifies the first electronic device 20 to perform enumeration, and during the enumeration process, the communication conversion device 10 is responsible for communication between the first electronic device 20 and the second electronic device 30. For example, the communication conversion apparatus 10 acquires USB device type information of the second electronic device 30 from the second electronic device 30 through a USB communication connection, and transmits to the first electronic device 20 through a wireless communication connection. At this time, the communication conversion apparatus 10 is mapped to the USB device indicated by the USB device type information, and is responsible for data communication between the first electronic device 20 and the second electronic device 30.

The enumeration process of the USB communication means that, after the slave device of the USB communication is connected to the master device, the master device communicates with the slave device through the enumeration process to obtain USB device type information of the slave device, thereby knowing what type of USB device the slave device is, and loading a corresponding driver. The entire process from the connection of the slave device to the master device to the end of enumeration includes the following state changes: connection state, power supply state, default state, address state, configuration state, and suspend state. During the enumeration process, the master and slave negotiate to determine functionally relevant configuration items, all of which are provided in the form of descriptors, including device descriptors, configuration descriptors, string descriptors, interface descriptors, endpoint descriptors, device definition descriptors. When the relevant function parameters are configured, the master device and the slave device can realize relevant functions according to specific USB device types.

When the first electronic device 20 inputs the correct Wi-Fi password, the first wireless communication module 101 may establish a Wi-Fi communication connection with the third wireless communication module 203 in the first electronic device 20, for transmitting a large amount of wireless communication data including files, pictures, audio, and the like.

In step S104, the communication conversion apparatus 10 obtains the first USB device type information of the first electronic device 20 through the first wireless communication module 101, and sends the first USB device type information to the second electronic device 30 through the first USB interface 103.

As shown in S1041 of fig. 10, the communication conversion apparatus 10 notifies the second electronic device 30 to perform enumeration. In the enumeration process, the communication conversion apparatus 10 acquires USB device type information of the first electronic device 20 from the first electronic device 20 through the wireless communication connection of the first wireless communication module 101, and sends the USB device type information to the second electronic device 30 through the first USB interface 103. Wherein the first USB device type information indicates the device types supported by the first electronic device 20, with specific reference to the table 1.

For example, when the first electronic device 20 and the second electronic device 30 perform data transmission, the device type supported by the first electronic device 20 may be a storage device (mass storage device), where the storage device mainly includes an optical drive, a usb disk, a U-shield, a removable hard disk, and so on. When the second electronic device 30 is surfing the internet through the first electronic device 20, the device type supported by the first electronic device 20 may be a communication device (communications device) mainly including a modem (modem).

In step S105, the communication conversion apparatus 10 and the second electronic device 30 perform USB data communication in accordance with the transmission requirement of the USB device type indicated by the first USB device type information, and the communication conversion apparatus 10 performs wireless data communication with the first electronic device 20 through the wireless communication connection of the first wireless communication module 101.

The communication conversion device 10 is configured to convert wireless data communication and USB data communication, and forward data to establish a data communication link between the first electronic device 20 and the second electronic device 30, so as to realize data communication between the first electronic device 20 and the second electronic device 30.

Regardless of the USB device type indicated by the first USB device type information, the first electronic device 20 and the second electronic device 30 may perform control transmission, so that the second electronic device 30 obtains information and status of the first electronic device 20. Through the data interaction, the second electronic device 30 can learn various device information such as how many data interfaces the first electronic device 20 has and how many available endpoints.

When the USB device type indicated by the first USB device type information is a storage device such as a USB disk, the first electronic device 20 and the second electronic device 30 may perform batch transmission. The batch transmission is unidirectional transmission and is mainly used for transmitting a large amount of data, the transmission mode has no requirement on data transmission time, but the accuracy of the data must be ensured, when the USB bus is busy, the transmission rate is slower, and when the USB bus is idle, the transmission rate is faster.

When the USB device type indicated by the first USB device type information is a language device such as a microphone, a sound box, or an image device such as a scanner, a digital camera, or a monitor device such as a display, the first electronic device 20 and the second electronic device 30 may also perform isochronous transmission. The speed of isochronous transmission is constant, and a large amount of data can be transmitted, but the success of each transmission can not be ensured because of no error control, and the method is suitable for the data transmission of audio and video.

As shown in fig. 11, when the communication conversion apparatus 10 is a wireless charging apparatus, a user may implement a USB communication function with a second electronic device using the wireless charging apparatus by selecting a function option of a transmission file in a USB connection manner at a user interface of the first electronic device 20.

As shown in fig. 12 and 13, taking the first electronic device 20 as a master device (e.g., a mobile phone) for USB communication and the second electronic device 30 as a slave device (e.g., an OTG device) for USB communication as an example, the communication conversion apparatus 10 may be a wireless charging apparatus. Wherein, as shown in fig. 12, in one possible implementation, the USB cable B may be a dedicated cable, and in this implementation, the first wireless communication module 101, the first USB interface 103, and the first processor 104 may be integrated on the USB connector C.

In another possible embodiment, as shown in fig. 14, when the communication conversion device 10 is not a wireless charging device, or the first electronic apparatus 20 and the wireless charging device do not support wireless reverse charging, other power sources may also be used to supply power to the communication conversion device 10.

Otherwise, the communication conversion apparatus 10 supplies power to the outside using the power supplied from the first electronic device 20.

S2022, the communication conversion apparatus 10 transmits the wireless configuration information to the first electronic device 20 through the wireless charging coil.

In step S203, the communication conversion apparatus 10 establishes a wireless communication connection with the first electronic device 20 through the first wireless communication module 101.

The second USB device type information indicates a device type supported by the second electronic device 30, where the device type supported by the second electronic device 30 may be a storage device such as a USB disk, a U shield, a mobile hard disk, or may be a man-machine interaction device such as a USB mouse, a USB keyboard, or the like.

In step S205, the communication conversion apparatus 10 and the second electronic device 30 perform USB data communication according to the transmission requirement of the USB device type indicated by the second USB device type information, and the communication conversion apparatus 10 performs wireless data communication with the first electronic device 20 through the wireless communication connection of the first wireless communication module 101.
