It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0037] Example 1

[0038] Figure 1 FIG. 0000085 is a flowchart of a data transmission method provided according to Example 1 of the present invention. This example is applicable to the situation where a first device sends data to be transmitted to a second device. This method can be executed by a data transmission device, which can be implemented in the form of software and / or hardware and integrated in an electronic device serving as the first device. Further, the electronic device includes, but is not limited to, a computer, a laptop computer, etc.

[0039] As Figure 1 shown, the method includes:

[0040] S110. Establish a communication connection with a first local proxy server in the first device through a first client in the first device.

[0041] The first client can be a client in the first device. The client can be a running instance of an application program on the electronic device, responsible for receiving data, presenting data, and processing user input and interaction.

[0042] The first local proxy server can be a proxy server created locally in the first device. In the embodiments of the present invention, the proxy server can be understood as a computer system or software service between the client and the end actually communicating with the client. The proxy server can intercept the data transmitted by the client when the client transmits data to the end actually communicating, and transmit the intercepted data through the proxy server. Among them, the end actually communicating with the client can be a client in a device different from the first device.

[0043] In this step, the first device includes a first client and a first local proxy server. A socket (also known as a socket) can be created through the first client, and a communication connection can be established with the socket of the first local proxy server through the created socket. When establishing the communication connection, the communication address of the first local proxy server can be set to the local loopback address of the first device.

[0044] Among them, the socket can be regarded as an endpoint for communication between the first client and the first local proxy server, forming a channel for network communication. The local loopback address can be a special Internet Protocol (IP) address in a computer network, which allows the electronic device to send network data packets to itself through its own network interface without leaving the device.

[0045] S120. Transmit the data to be transmitted to the first local proxy server through the first client; wherein, the data to be transmitted includes the data that the first client in the first device needs to transmit to the second client in the second device through wireless transmission; the first device and the second device are connected through a Universal Serial Bus (USB).

[0046] The data to be transmitted can be the data that the first client in the first device needs to transmit to the second client in the second device. The second device can be an electronic device communicating with the first device, and the second client can be the client in the second device.

[0047] Universal Serial Bus (USB) can be a standard interface technology widely used between electronic devices. The first device and the second device involved in the present invention can communicate through the USB protocol.

[0048] The data to be transmitted can include the data that the first client needs to transmit to the second client through wireless transmission, specifically, it can be data related to upper-layer services, such as wireless transmission data or data involved in device mirroring. Among them, the wireless transmission method can be implemented based on Transmission Control Protocol / Internet Protocol (TCP / IP), which is not limited here. The upper-layer service can be a service or logic processing module at a relatively high level in the application layer. The upper-layer service does not directly face users, but processes complex business rules, data operations, and algorithm executions. There is a close connection between the client and the upper-layer service. For example, the client can send requests to the upper-layer service to request data or services, and the upper-layer service can also push data to the client, etc.

[0049] In the case where a network communication channel is established between the socket of the first client and the socket of the first local proxy server in S110, the data to be transmitted can be transmitted to the first local proxy server through the first client in this step.

[0050] S130. Transmit the data to be transmitted to the second local proxy server in the second device based on the USB protocol through the first local proxy server, so that the second client can obtain the data to be transmitted from the second local proxy server.

[0051] The second local proxy server can be a proxy server created locally in the second device.

[0052] In this step, when the first local proxy server obtains the data to be transmitted, synchronous USB mass writing can be performed to encapsulate the data to be transmitted into the data required to be transmitted by the USB protocol, and the data to be transmitted is transmitted from the first device to the second device through the USB protocol.

[0053] In the second device, the second local proxy server can obtain the data to be transmitted that is transmitted from the first device to the second device based on the USB protocol; the second client in the second device can establish a communication connection with the second local proxy server, and the second client can obtain the data to be transmitted from the second local proxy server; the second client then reports the obtained data to be transmitted to the upper-layer service corresponding to the second client for processing.

[0054] Through the above operations, when the first device and the second device communicate through the USB protocol, the upper-layer service can communicate through the TCP / IP protocol, thereby reducing the dependence of service developers on the USB protocol.

[0055] In the technical solution of the embodiment of the present invention, the first device includes a first client and a first local proxy server, the second device includes a second client and a second local proxy server, and the first device and the second device are connected through USB; the first client transmits the data to be transmitted that needs to be transmitted to the second client in a wireless transmission manner to the first local proxy server; the first local proxy server transmits the data to be transmitted to the second local proxy server based on the USB protocol, and the second client can obtain the data to be transmitted from the second local proxy server. This solution can simulate the USB protocol as a wireless transmission, that is, through the communication between the first client and the first local proxy server, the communication between the second client and the second local proxy server, and the communication between the first local proxy server and the second local proxy server based on the USB protocol, to simulate the wireless communication between the first client and the second client; service developers do not need to care whether the underlying is based on the USB protocol transmission or wireless transmission, and can be adapted through wireless transmission, increasing the portability and compatibility of the upper-layer service corresponding to the client; service developers do not need to understand the content of the USB protocol, reducing the development difficulty.

[0056] In one embodiment, transmitting the data to be transmitted to the first local proxy server through the first client includes:

[0057] Through the first client, call the first sending function adapted for wireless transmission, and transmit the data to be transmitted to the first local proxy server based on the socket handle of the first local proxy server.

[0058] The first sending function can be a function for transmitting data to be transmitted to the first local proxy server through the first client, and can be a function adapted for wireless transmission, such as the send function adapted for the TCP / IP protocol. The send function can be a function for sending data in socket communication.

[0059] The socket handle can be understood as an identifier used to uniquely identify an opened socket. The socket handle of the first local proxy server is the identifier for uniquely identifying the socket of the first local proxy server.

[0060] Among them, the first sending function can be expressed as: send(sockfd, buffer, actual_length, MSG_DONTWAIT). sockfd can be the socket handle of the first local proxy server; buffer indicates the buffer in the first client that stores the data to be transmitted; actual_length indicates the length of the data that actually needs to be sent in the above buffer, that is, the length of the data to be transmitted; MSG_DONTWAIT can be a non-blocking sending mode flag set during socket communication, and its function is to make the operation of the first sending function into a non-blocking sending mode, that is, if the sending operation cannot be completed immediately, an error-indicating message will be returned immediately.

[0061] Through the first client, by calling the first sending function, the data to be transmitted stored in the buffer of the first sending function can be transmitted to the first local proxy server indicated by sockfd through socket communication, the length of the transmitted data is the length indicated by actual_length, and the data transmission mode is the non-blocking sending mode.

[0062] In one embodiment, transmitting the data to be transmitted to the second local proxy server in the second device based on the USB protocol through the first local proxy server includes:

[0063] Through the first local proxy server, by calling the second sending function adapted for the USB protocol, the data to be transmitted is transmitted to the second local proxy server in the second device based on the USB handle of the first device and the USB handle of the second device.

[0064] The second sending function can be a function for transmitting data to be transmitted to a second local proxy server through a first local proxy server, and can be the libusb_bulk_transfer function adapted to the USB protocol. The libusb_bulk_transfer function can be an application programming interface function provided by the libusb library for handling bulk data transfer on a USB device. Libusb is a cross-platform library that allows developers to write application programs that can access USB devices.

[0065] A USB handle can be understood as an identifier used to uniquely identify an opened USB device. The USB handle of the first device is the identifier used to uniquely identify the first device as a USB device. The USB handle of the second device is the identifier used to uniquely identify the second device as a USB device.

[0066] Among them, the second sending function can be expressed as: libusb_bulk_transfer(dev_handle, endpoint, buffer, length, &actual_length, 0). dev_handle can be the USB handle of the first device, indicating the USB device being operated on; endpoint can be the USB handle of the second device, indicating the endpoint where data is sent; buffer indicates the buffer in the first local proxy server that stores the data to be transmitted. When the first local proxy server obtains the data to be transmitted, it can store it in its own buffer; length indicates the maximum length of data transfer; &actual_length indicates the length of the data that actually needs to be sent in the above buffer, that is, the length of the data to be transmitted.

[0067] Through the first local proxy server, by calling the second sending function, the data to be transmitted stored in the buffer of the second sending function can be transmitted to the second device indicated by endpoint through the first device indicated by dev_handle based on USB protocol communication, and the length of the transmitted data is the length indicated by &actual_length. Correspondingly, in the second device, the second local proxy server can obtain the data to be transmitted from the first device to the second device based on the USB protocol in a similar manner.

This method can be executed by a data transmission device, which can be implemented in the form of software and / or hardware and integrated in an electronic device serving as the second device. Further, the electronic device includes, but is not limited to, a computer, a laptop computer, etc.

[0070] It should be noted that the embodiments of the present invention are described from the perspective of the data receiver in Embodiment 1 above. Contents not described in detail in this embodiment can be referred to in Embodiment 1 above.

[0071] As Figure 2 shown, the method includes:

[0072] S210. Establish a communication connection with a second local proxy server in the second device through a second client in the second device.

[0073] The second client can be a client in the second device. The second local proxy server can be a proxy server created locally in the second device.

[0074] In this step, the second device includes a second client and a second local proxy server. A socket (also known as a socket) can be created through the second client, and a communication connection can be established with the socket of the second local proxy server through the created socket. When establishing the communication connection, the communication address of the second local proxy server can be set as the local loopback address of the second device.

Specifically, it may be data related to upper-layer services, such as wireless transmission data or data involved in device mirroring. Among them, the wireless transmission manner may be implemented based on the Transmission Control Protocol / Internet Protocol (TCP / IP), which is not limited here.

[0079] In the case where the first local proxy server encapsulates the data to be transmitted into the data to be transmitted by the USB protocol and transmits the data to be transmitted from the first device to the second device through the USB protocol, the operations in this step can be executed. In this step, through the second local proxy server, USB mass storage reading can be performed to read the data to be transmitted that the first local proxy server transmits from the first device to the second device through the USB protocol.

[0080] S230. Obtain the data to be transmitted from the second local proxy server through the second client.

[0081] In the case of establishing a network communication channel between the socket of the second client and the socket of the second local proxy server in S210, and obtaining the data to be transmitted transmitted by the first local proxy server in the first device through the second local proxy server in S220, in this step, the data to be transmitted can be read from the second local proxy server through the second client. The second client can also report the read data to be transmitted to the upper-layer service corresponding to the second client for processing.

[0082] Through the above operations, in the case where the first device and the second device communicate through the USB protocol, the upper-layer service can communicate through the TCP / IP protocol, thereby reducing the dependence of service developers on the USB protocol.
