Embodiment 1

[0042] figure 1 and figure 2 It is a schematic diagram of the implementation flow of the method for supporting different network interfaces provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes:

[0043]Step 110: The USB device provides MBIM configuration and MODEM configuration at the same time.

[0044] In the embodiment of the present invention, the USB device provides two sets of different configurations, one of which is the MBIM configuration and the other is the MODEM configuration. Different operating systems can only support a different configuration, for example, open source LINUX system and Apple's MAC system support MODEM configuration.

[0045] In another case, the operating system can theoretically support two configurations, but in the end only one of them can be selected for support. For example, the current open source LINUX system supports the MODEM configuration in the same way as the MAC system, and MBIM c...

Embodiment 2

[0068] In order to further illustrate the enumeration and interaction process of the MBIM configuration and MODEM configuration by the terminal operating system, Embodiment 2 of the present invention provides a method for supporting MBIM by taking the WIN8 system as an example. It should be noted that currently Microsoft has integrated related applications such as MBIM driver and MBIM dial-up setting on the WIN8 system.

[0069] Figure 4 The terminal operating system provided for Embodiment 2 of the present invention is a schematic flow diagram of a method for supporting MBIM of the WIN8 system, as shown in Figure 4 As shown, the method includes:

[0070] Step 310: The USB device is inserted into the terminal running the WIN8 system.

[0071] Step 320: WIN8 system selects configuration 0.

[0072] In step 320, firstly, the WIN8 system performs an enumeration process, and after recognizing that the USB device has two sets of configurations, it recognizes configuration 0, t...

Embodiment 3

[0077] In order to further illustrate the enumeration and interaction process between the MBIM and the MODEM by the terminal operating system, Embodiment 3 of the present invention provides a method for supporting the MODEM by taking the MAC system as an example. It should be noted that because MBIM is a virtual network card protocol developed by Microsoft and other manufacturers, Apple does not participate in it. Therefore, based on related conventions, Apple cannot integrate related drivers and applications in the MAC operating system. Therefore, all MAC operating systems do not support network card devices in the form of MBIM. The MODEM protocol has been supported as early as MAC10.4, so the drivers and applications in the MAC operating system can stably support the MODEM protocol.

[0078] Figure 5 The terminal operating system provided for Embodiment 3 of the present invention is a schematic diagram of the implementation flow of the method for supporting the MODEM of th...

Abstract

The invention discloses a method for supporting various network interfaces. The method of the invention comprises: a general serial bus (USB) device simultaneously provides a mobile broadband interface model (MBIM) configuration and a modulator-demodulator (MODEM); the USB device reports MBIM configuration information and the MODEM configuration information to a terminal operation system; and the terminal operation system chooses the corresponding MBIM configuration or the MODEM configuration according to the support condition of the terminal operation system. The invention also discloses an USB device and a system for supporting various network interfaces.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to a method for supporting different network interfaces, Universal Serial Bus (USB, Universal Serial Bus) equipment and a system. Background technique [0002] With the development of technology, the application of USB-based network adapters is becoming more and more common. A network device based on a USB modem (MODEM, Modulator-demodulator) is the most widely used network adapter. Here, the broad definition of MODEM is a device that converts a digital signal into an analog signal through modulation at the sending end, and converts the analog signal into a digital signal through demodulation at the receiving end. USB MODEM is only the end part of MODEM data transmission, and all digital signals are transmitted inside. Early MODEM transmission rates were only 14.4K, 28.8K and 33.6K. With the development of hardware and software technology, the transmission rate of MODEM has alr...
