Detailed ways

First, some concepts involved in this application are described.

The terms "first", "second", etc. involved in the embodiments of the present application are only used to distinguish features of the same type and cannot be understood as indicating relative importance, quantity, order, etc.

The terms "exemplary" or "for example" and the like in the embodiments of the present application are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the related concepts in a specific way.

The terms "coupling" and "connection" involved in the embodiments of the present application should be understood in a broad sense. For example, they may refer to a direct physical connection, or an indirect connection achieved through electronic devices, such as a connection achieved through resistors, inductors, capacitors or other electronic devices.

At present, electronic devices are usually equipped with USB interfaces, which can be used as data transmission interfaces. By connecting the USB interfaces of two electronic devices with a USB cable, wired data transmission between the two electronic devices can be realized. However, the installation of USB interfaces will affect the waterproof performance, dustproof performance and plug-in life of electronic devices, and will also occupy the motherboard space, which is not conducive to the ultra-thinness of electronic devices. Therefore, the removal of USB interfaces is the current trend in the development of electronic devices.

If the USB interface is removed, the data transmission function of the electronic device needs to be realized through wireless data communication. In the prior art, when two electronic devices perform wireless data communication, both electronic devices need to install an adaptive application or driver in advance, and then the user manually connects them. This method requires the user to have certain computer operation skills.

To this end, as shown in FIG1 , an embodiment of the present application provides a communication conversion system, which includes a first electronic device 20, a second electronic device 30, and a communication conversion device 10. The first electronic device 20 is an electronic device without a USB interface. The second electronic device 30 is a device for data transmission with the first electronic device 20. The communication conversion device 10 is used 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 can be used as a slave device for USB communication, and the second electronic device 30 can be used as a master 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 personal computer (PC device), a laptop, etc. Alternatively, the first electronic device 20 can also be used as a master device for USB communication, and the second electronic device 30 can be used as 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 flash drive, a USB mouse, a USB keyboard, a USB shield, etc.

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

When the first electronic device 20 acts as the master device of USB communication and the second electronic device 30 acts as the slave device of USB communication, the communication conversion device 10 notifies the first electronic device 20 to perform enumeration. During the enumeration process, the communication conversion device 10 is responsible for the communication between the first electronic device 20 and the second electronic device 30. For example, the communication conversion device 10 obtains the USB device type information of the second electronic device 30 from the second electronic device 30 through the USB communication connection, and sends it to the first electronic device 20 through the wireless communication connection. At this time, the communication conversion device 10 is mapped to the USB device indicated by the USB device type information, and is responsible for the data communication between the first electronic device 20 and the second electronic device 30.

The enumeration process of USB communication refers to that when the slave device of USB communication is connected to the master device, the master device communicates with the slave device through the enumeration process to obtain the USB device type information of the slave device, so as to know what type of USB device the slave device is and load the corresponding driver. The whole process from the connection of the slave device to the end of enumeration includes the following state changes: connection state, power supply state, default state, address state, configuration state and suspended state. During the enumeration process, the master device and the slave device negotiate to determine the function-related configuration items. All configuration items are provided in the form of descriptors, including device descriptors, configuration descriptors, string descriptors, interface descriptors, endpoint descriptors, and device-limited descriptors. After the relevant function parameters are configured, the master device and the slave device can implement relevant functions according to the specific USB device type.

The USB device types specified in the USB bus technical specification are shown in Table 1:

The first electronic device 20 acquires the wireless configuration information by scanning the QR code 105 on the communication conversion device 10 through the camera 208.

Taking the first electronic device 20 shown in FIG. 4 to FIG. 8 as a slave device of USB communication (such as a mobile phone), and the second electronic device 30 as a master device of USB communication (such as a PC device) as an example, the above wireless communication system can execute the communication conversion method shown in FIG. 9, which specifically includes steps S101 to S105:

Step S101 : After the communication conversion device 10 is powered on, the first processor 104 recognizes that the power supply comes from the first USB interface 103 .

When the first USB interface 103 of the communication conversion device 10 is connected to the second USB interface 301 of the second electronic device 30, the second electronic device 30 can supply power to the communication conversion device 10 through the second USB interface 301 and the first USB interface 103, so that the communication conversion device 10 is powered on.

Alternatively, the first electronic device 20 can obtain the wireless configuration information from the communication conversion device 10 by using the camera 208 to scan the QR code 105 as shown in FIG8.

For the communication conversion device 10 actively sending the wireless configuration information to the first electronic device 20 in a wireless manner: a button may be provided on the communication conversion device 10, and when the user presses the button, the communication conversion device 10 is triggered to send the wireless configuration information to the first electronic device 20 through the wireless charging coil shown in FIG. 4 or FIG. 5, or through the Bluetooth module shown in FIG. 7. Alternatively, the communication conversion device 10 adopts a continuous broadcasting method to send the wireless configuration information to the first electronic device 20 through the wireless charging coil shown in FIG. 4 or FIG. 5, or through the Bluetooth module shown in FIG. 7.

As shown in FIG. 10 , the communication conversion device 10 sends wireless configuration information to the first electronic device 20 via the wireless charging coil shown in FIG. 4 or FIG. 5 , specifically including steps S1021-S1024:

S1021 . The wireless charging coil in the charging base A broadcasts a PING token packet to determine that the communication conversion device 10 establishes a wireless communication connection with the first electronic device 20 through the wireless charging coil.

S1022: The first electronic device 20 detects the wireless charging coil, and establishes a wireless connection with the communication conversion device 10 through the wireless charging coil.

If the first electronic device 20 is close to the charging base A, so that the wireless charging coil 205 of the first electronic device 20 is electromagnetically coupled with the wireless charging coil of the charging base A, the first electronic device 20 can detect the wireless charging coil and receive a PING token packet through the wireless charging coil 205 .

If the first electronic device 20 is ready to receive subsequent messages, an acknowledgement (ACK) message is fed back through the wireless charging coil 205 ; otherwise, a non-acknowledgement (NAK) message or a STALL message is fed back through the wireless charging coil 205 .

If the communication conversion device 10 receives an ACK message, it can be determined that the communication conversion device 10 establishes a wireless communication connection with the first electronic device 20 through the wireless charging coil, and executes S1023. If the communication conversion device 10 receives a NAK message or a STALL message, the wireless charging process is executed.

S1023 , performing a BC1.2 test on the first USB interface 103 to determine whether the communication conversion device 10 has established a USB communication connection with the second electronic device 30 through the first USB interface 103 .

S1024: The communication conversion device 10 sends wireless configuration information to the first electronic device 20 via the wireless charging coil.

The communication conversion device 10 may use a customized wireless communication protocol to send wireless configuration information to the first electronic device via the wireless charging coil.

Step S103 : the communication conversion device 10 establishes a wireless communication connection with the first electronic device 20 via the first wireless communication module 101 .

After the communication conversion device 10 completes identity authentication with the first electronic device 20 through wireless configuration information (including SSID, Wi-Fi password, MAC address and other information), the first processor 104 controls the first wireless communication module 101 to establish a wireless communication connection with the first electronic device 20.

Exemplarily, when the first wireless communication module 101 is a Wi-Fi module, identity authentication can be performed through a Wi-Fi password. After the first electronic device 20 enters the correct Wi-Fi password, the first wireless communication module 101 can 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, etc.

Step S104 : The communication conversion device 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 device 10 notifies the second electronic device 30 to perform enumeration. During the enumeration process, the communication conversion device 10 obtains the 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 it to the second electronic device 30 through the first USB interface 103. Among them, the first USB device type information indicates the device type supported by the first electronic device 20, as shown in Table 1.

Exemplarily, 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 mass storage device, which mainly includes an optical drive, a USB flash drive, a USB shield, a mobile hard disk, etc. When the second electronic device 30 accesses the Internet through the first electronic device 20, the device type supported by the first electronic device 20 may be a communications device, which mainly includes a modem.

Step S105 , the communication conversion device 10 and the second electronic device 30 perform USB data communication according to the transmission requirements of the USB device type indicated by the first USB device type information, and the communication conversion device 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 used to realize the conversion between wireless data communication and USB data communication, and forward the data to establish a data communication link between the first electronic device 20 and the second electronic device 30, so as to realize the 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 can perform control transmission, so that the second electronic device 30 obtains information and status of the first electronic device 20. Through data interaction, the second electronic device 30 can understand various device information such as how many data interfaces the first electronic device 20 has, how many available endpoints there are, etc.

When the USB device type indicated by the first USB device type information is a storage device such as a USB flash drive, the first electronic device 20 and the second electronic device 30 can perform batch transmission. Batch transmission is a one-way transmission, mainly used for the transmission of large amounts of data. This transmission method has no requirements on the data transmission time, but must ensure the accuracy of the data. When the USB bus is busy, the transmission rate is slow, and when the USB bus is idle, the transmission rate is fast.

When the USB device type indicated by the first USB device type information is a language device such as a microphone or a speaker, an imaging device such as a scanner or a digital camera, or a monitoring device such as a display, the first electronic device 20 and the second electronic device 30 can also perform isochronous transmission. The rate of isochronous transmission is constant and a large amount of data can be transmitted, but since there is no error control, it cannot guarantee that each transmission is successful, and is suitable for audio and video data transmission.

As shown in FIG. 11 , when the communication conversion device 10 is a wireless charging device, the user can select the file transfer function option in the USB connection mode in the user interface of the first electronic device 20 and use the wireless charging device to implement the USB communication function with the second electronic device.

As shown in Figures 12 and 13, taking the first electronic device 20 as a USB communication master device (such as a mobile phone) and the second electronic device 30 as a USB communication slave device (such as an OTG device) as an example, the communication conversion device 10 can be a wireless charging device. As shown in Figure 12, in a possible implementation, the USB cable B can be a dedicated cable. In this implementation, the first wireless communication module 101, the first USB interface 103 and the first processor 104 can be integrated on the USB connector C. As shown in Figure 13, in another possible implementation, the first wireless communication module 101, the first USB interface 103 and the first processor 104 can be integrated on the charging base A.

As shown in FIG. 14 , taking the first electronic device 20 as a USB communication master device (such as a mobile phone) and the second electronic device 30 as a USB communication slave device (such as an OTG device) as an example, the communication conversion device 10 may not be a wireless charging device.

Taking the first electronic device 20 shown in FIGS. 12 to 14 as a USB communication master device (such as a mobile phone) and the second electronic device 30 as a USB communication slave device (such as an OTG device) as an example, the above wireless communication system can execute the communication conversion method shown in FIG. 15, which specifically includes steps S201 to S205:

Step S201 : After the communication conversion device 10 is powered on, the first processor 104 recognizes that the power supply does not come from the first USB interface 103 .

Since the OTG device needs to be powered by an external device, as shown in Figures 12 and 13, in a possible implementation, when the communication conversion device 10 is a wireless charging device, and the first electronic device 20 and the wireless charging device support wireless reverse charging (the first electronic device 20 charges the wireless charging device), as shown in S2011 of Figure 16, the user sets the first electronic device 20 to the wireless reverse charging mode. At this time, the first electronic device 20 can power the communication conversion device 10 through the wireless charging coil, so that the communication conversion device 10 is powered on. At this time, the first processor 104 in the communication conversion device 10 can recognize that the power comes from the wireless charging coil.

As shown in FIG. 14 , in another possible implementation, when the communication conversion device 10 is not a wireless charging device, or the first electronic device 20 and the wireless charging device do not support wireless reverse charging, other power sources may also be used to power the communication conversion device 10 .

Step S202: The first electronic device 20 obtains wireless configuration information.

The first electronic device 20 can actively obtain wireless configuration information from the communication conversion device 10 in a wireless manner. For example, as shown in Figure 14, the first electronic device 20 can use the near field communication module 206 as an information acquisition module to obtain wireless configuration information from the communication conversion device 10 by identifying the NFC tag of the near field communication module in the communication conversion device 10.

The communication conversion device 10 can actively send wireless configuration information to the first electronic device 20 in a wireless manner. For example, as shown in FIG. 16 , the communication conversion device 10 sends the wireless configuration information to the first electronic device 20 through the wireless charging coil shown in FIG. 12 and FIG. 13 , specifically including steps S2021-S2022:

S2021, the communication conversion device 10 detects whether an OTG device is connected.

When the OTG device is connected to the communication conversion device 10 through the second USB interface 301 and the first USB interface 103, the first processor 104 in the communication conversion device 10 can detect the access of the OTG device and execute S2022. Otherwise, the communication conversion device 10 uses the power provided by the first electronic device 20 to supply power externally.

S2022: The communication conversion device 10 sends wireless configuration information to the first electronic device 20 via the wireless charging coil.

Step S203 : The communication conversion device 10 establishes a wireless communication connection with the first electronic device 20 through the first wireless communication module 101 .

Step S204 : The communication conversion device 10 obtains the second USB device type information of the second electronic device 30 through the first USB interface 103 , and sends the second USB device type information to the first electronic device 30 through the first wireless communication module 101 .

As shown in S2041 of FIG. 16 , the communication conversion device 10 notifies the first electronic device 20 to perform enumeration. During the enumeration process, the communication conversion device 10 obtains the USB device type information of the second electronic device 30 from the second electronic device 30 through the USB communication connection of the first USB interface 103, and sends it to the first electronic device 20 through the first wireless communication module 101. Among them, the second USB device type information indicates the device type supported by the second electronic device 30. The device type supported by the second electronic device 30 can be a storage device such as a USB flash drive, a USB shield, a mobile hard disk, or a human-computer interaction device such as a USB mouse and a USB keyboard.

Regardless of the USB device type indicated by the second USB device type information, the first electronic device 20 and the second electronic device 30 must perform control transmission so that the first electronic device 20 obtains the information and status of the second electronic device 30 .

When the USB device type indicated by the second USB device type information is a storage device such as a USB flash drive, the first electronic device 20 and the second electronic device 30 can perform batch transmission.

When the USB device type indicated by the second USB device type information is a human-computer interaction device such as a USB keyboard or a USB mouse, the first electronic device 20 and the second electronic device 30 can perform interrupt transmission. The amount of data received and sent in interrupt transmission is small, and it is usually periodic transmission.
