Description

USB connection establishing method and device

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a method and an apparatus for establishing a Universal Serial Bus (USB) connection.

Background

At present, wireless devices using Wi-Fi (wireless fidelity) technology have two operating modes: single frequency and dual frequency. The single-frequency Wi-Fi works in a 2.4GHz frequency band; the dual-frequency Wi-Fi can work in two frequency bands of 2.4GHz and 5GHz, and can be flexibly selected according to actual conditions.

The wireless device may use a USB interface while using Wi-Fi. USB is a serial bus standard for supporting the connection between USB devices and external devices, and is also a technical specification of input/output interfaces, and is widely used in information communication products such as personal computers and mobile devices. The standards related to USB include USB 1.0, USB2.0 fs (full speed), USB 3.0, USB3.1 Generation (GEN)1, and USB3.1 GEN 2. The data transmission speed specified by each standard is different. For example, the USB 1.0 maximum data transfer speed is only 1.5 Mbps; the USB2.0 FS maximum data transfer speed is 12 Mbps.

With the improvement of the requirement on the transmission speed, at present, the maximum data transmission speed of the USB3.1 GEN1 can reach 5Gbps, and the maximum data transmission speed of the USB3.1 GEN2 can reach 10 Gbps. However, when data is transmitted through the USB3.1 GEN1 standard, the reference frequency of each data line is 2.5GHz, which may interfere with signals in the 2.4GHz band of Wi-Fi. Correspondingly, when data transmission is carried out through the USB3.1 GEN2 standard, the reference frequency of each data line is 5GHz, the frequency can generate interference on signals of a Wi-Fi 5GHz frequency band, and meanwhile, because the reference frequency is wide in bandwidth and can cover signals of a Wi-Fi 2.4GHz frequency band, the reference frequency can also generate interference on signals of the Wi-Fi 2.4GHz frequency band.

As can be seen from the foregoing description, when the wireless device uses Wi-Fi, if the wireless device uses USB3.1 GEN1 or USB3.1 GEN2 to transmit data at the same time, the USB3.1 GEN1 or USB3.1 GEN2 may interfere with the Wi-Fi signal, thereby affecting the user experience.

At present, no good solution exists for reducing the interference of the signal transmitted by the USB interface to the Wi-Fi signal.

In the embodiment of the present application, the terminal may be a wireless terminal or a wired terminal, and may be, for example, a mobile phone, a computer, a tablet computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable device, an electronic book reader (e-book reader), and the like.

Based on the above discussion, as shown in fig. 3, a flow chart of a USB connection establishing method provided in an embodiment of the present application is schematically illustrated.

As shown in fig. 3, the method specifically includes the following steps:

step 301: after a terminal starts to establish a first USB connection according to a first USB standard, or after the terminal establishes the first USB connection according to the first USB standard, when a Wi-Fi module of the terminal is in a working state, determining a second USB standard according to a working frequency band supported by the Wi-Fi module and a first preset configuration strategy, or determining the second USB standard according to the current working frequency band of the Wi-Fi module and a second preset configuration strategy;

step 302: and when the terminal determines that the first USB standard is different from the second USB standard, establishing a second USB connection according to the second USB standard.

In step 301, the first USB standard may be a USB standard preset by the terminal, that is, a USB standard preferentially selected by the terminal each time a USB connection is established. The first USB standard may be any one of USB standards supported by the terminal, and for example, may be USB2.0 FS or the like.

It should be noted that, in the embodiment of the present application, the highest USB standard supported by the terminal is at least USB3.1 GEN1, and of course, the terminal may also support USB standards such as USB3.1 GEN 2. Because the USB standard has the characteristic of downward compatibility, the terminal supporting USB3.1 GEN1 can also support USB standards of versions below USB3.1 GEN1, such as USB2.0 FS, USB 1.0; the terminal supports the USB3.1 GEN2, and can also support the USB standard of the version below the USB3.1 GEN 2. For example, the terminal supports USB3.1 GEN2, then according to the USB standard from high to low, the terminal also supports the USB standards: USB3.1 GEN1, USB2.0 FS, USB 1.0, where the higher the version of the USB standard, the higher the transfer rate of the USB.

In the embodiment of the application, the terminal may determine whether the Wi-Fi module is in the working state when the terminal starts to establish the first USB connection according to the first USB standard, or may determine whether the Wi-Fi module is in the working state after the terminal completes to establish the first USB connection according to the first USB standard. Whether the Wi-Fi module is in the working state or not can be judged by judging whether a switch of the Wi-Fi function is turned on or not, and whether the Wi-Fi module is in the working state or not can be judged by judging whether data are transmitted in a Wi-Fi mode or not.

If the terminal determines that the Wi-Fi module of the terminal is in a closed state, a USB standard can be randomly selected from the USB standards supported by the terminal as a second USB standard; the first USB standard may also be considered as the second USB standard, i.e. the USB standard is not re-determined. Optionally, if the terminal determines that the Wi-Fi module of the terminal is in the off state, the USB standard with the highest transmission speed supported by the terminal may be accurately defined as the second USB standard. Of course, the above is only an example, and there may be other ways to determine the second USB standard, which will not be described herein again.

When the Wi-Fi module of the terminal is in a working state, the USB standard which does not conflict with the working frequency band of the current Wi-Fi module in the USB standard supported by the terminal and has the highest transmission rate can be accurately determined as the second USB standard. Certainly, the second USB standard may also be determined in other manners in this embodiment of the application, and in a first possible implementation manner, the second USB standard may be determined according to the working frequency band supported by the Wi-Fi module and the first preset configuration policy; in a second possible implementation manner, the second USB standard may be determined according to the current operating frequency band of the Wi-Fi module and a second preset configuration policy.

The first preset configuration policy or the second preset configuration policy may be stored in a configuration file, and when the terminal needs to determine the second USB standard, the terminal may read the first preset configuration policy or the second preset configuration policy through the configuration file, so as to quickly determine the first preset configuration policy or the second preset configuration policy.

In conjunction with the above description, how to determine the second USB standard when the Wi-Fi module is in the operating state is described in detail below. For convenience of description, in the following description, except for a scenario where the terminal at least supports USB3.1 GEN1, the terminal at least supports USB3.1 GEN2 is taken as an example for description, and the scenario where the terminal at least supports USB3.1 GEN2 may refer to the following description, and is not described herein again.

In a first possible implementation manner, the first preset configuration policy is:

when the working frequency band supported by the Wi-Fi module is a 2.4GHz frequency band, the USB standard adopted by the USB module of the terminal when working is any one of USB2.0 FS and USB standards of versions below USB2.0 FS; or when the working frequency band supported by the Wi-Fi module at least comprises a 5GHz frequency band, the USB standard adopted by the USB module of the terminal in working is any one of USB3.1 GEN1 and USB standards of versions below USB3.1 GEN 1.

It should be noted that the working frequency bands supported by the Wi-Fi module at least include a 5GHz frequency band, which may mean: the working frequency band supported by the Wi-Fi module is a 5GHz frequency band, or the working frequency band supported by the Wi-Fi module is a 2.4GHz frequency band and a 5GHz frequency band.

And the terminal selects one USB standard as a second USB standard according to the working frequency band supported by the Wi-Fi module according to the first preset configuration strategy. Specifically, when determining that the working frequency band supported by the Wi-Fi module is the 2.4GHz frequency band, the terminal may determine any one of USB standards of USB 2.0F and USB2.0 FS versions below as the second USB standard; when the terminal determines that the working frequency band supported by the Wi-Fi module at least comprises a 5GHz frequency band, any one USB standard of USB3.1 GEN1 and USB standards of versions below USB3.1 GEN1 can be accurately defined as a second USB standard.

Further, in this embodiment of the application, when the terminal determines the second USB standard according to the working frequency band supported by the Wi-Fi module and the first preset configuration policy, the USB standard with the highest transmission speed in the USB standards adopted by the USB module of the terminal in the first preset configuration policy may be accurately defined as the second USB standard according to the working frequency band supported by the Wi-Fi module. In combination with the foregoing description, when determining that the operating frequency band supported by the Wi-Fi module is the 2.4GHz frequency band, the terminal determines the USB2.0 FS as the second USB standard. And when the terminal determines that the working frequency bands supported by the Wi-Fi module at least comprise a 5GHz frequency band, determining the USB3.1 GEN1 as a second USB standard.

In order to avoid interference, in this embodiment of the present application, if the current working frequency band of the Wi-Fi module of the terminal is a 2.4GHz frequency band, and the working frequency band supported by the Wi-Fi module of the terminal at least includes a 5GHz frequency band, the terminal needs to adjust the working frequency band of the Wi-Fi module of the terminal to the 5GHz frequency band while establishing the second USB connection according to the USB3.1 GEN 1. Specifically, when the terminal determines the USB3.1 GEN1 as the second USB standard, the terminal determines whether the current working frequency band of the Wi-Fi module is the 2.4GHz frequency band, and if the current working frequency band of the Wi-Fi module is the 2.4GHz frequency band, the terminal closes the Wi-Fi connection of the current 2.4GHz frequency band and starts to establish the Wi-Fi connection of the 5GHz frequency band. It should be noted that the wireless local area network standard adopted by the terminal to establish the Wi-Fi connection in the 5GHz band may be determined according to an actual situation, and is not described herein again.

In the method, when the terminal determines the second USB standard, whether the current working frequency band of the Wi-Fi module is 2.4GHz or 5GHz, the terminal may need to adjust the current working frequency band of the Wi-Fi module after finally determining the second USB standard, so as to avoid the selected second USB standard from interfering with the current working frequency band of the Wi-Fi module.

In a second possible implementation manner, the second USB standard may be determined according to the current operating frequency band of the Wi-Fi module.

Specifically, in a second possible implementation manner, the second preset configuration policy may be:

when the working frequency band of the Wi-Fi module is 2.4GHz, the USB standard adopted by the USB module of the terminal when working is any one of USB2.0 FS and USB standards of versions below USB2.0 FS; or when the working frequency band of the Wi-Fi module is 5GHz, the USB standard adopted by the USB module of the terminal when working is any one of USB3.1 GEN1 and USB standards of versions below USB3.1 GEN 1.

And the terminal selects one USB standard as a second USB standard according to the second preset configuration strategy and the working frequency band of the Wi-Fi module. Specifically, when the terminal determines that the working frequency band in which the Wi-Fi module works is the 2.4GHz frequency band, the terminal may determine any one of USB standards of USB 2.0F and USB2.0 FS versions below as the second USB standard; when the working frequency band of the Wi-Fi module is determined to be the 5GHz frequency band, the terminal can accurately calibrate any one USB standard of USB3.1 GEN1 and USB standards of versions below the USB3.1 GEN1 to be the second USB standard.

Further, in this embodiment of the application, the terminal may accurately specify, as the second USB standard, a USB standard with a highest transmission speed in the USB standards adopted by the USB module of the terminal in the second preset configuration policy according to the working frequency band supported by the Wi-Fi module. With reference to the foregoing description, if the current working frequency band of the Wi-Fi module of the terminal is the 2.4GHz frequency band, determining the USB2.0 FS as the second USB standard; and if the current working frequency band of the Wi-Fi module of the terminal is a 5GHz frequency band, determining the USB3.1 GEN1 as a second USB standard.

Finally, in step 302, the terminal re-establishes the second USB connection according to the second USB standard after determining that the first USB standard is different from the second USB standard. Specifically, when the terminal is starting to establish a first USB connection, the terminal terminates the establishment of the first USB connection, and establishes a second USB connection according to the second USB standard; when the terminal has established the first USB connection, the terminal disconnects the first USB connection and reestablishes the second USB connection according to the second USB standard.

Correspondingly, if the terminal determines that the first USB standard is the same as the second USB standard, the terminal continues to work with the first USB connection as the standard.

The above method is described in detail below with reference to specific examples.

Fig. 4 is a flowchart of a USB connection establishment method according to an embodiment of the present application.

Step 401: after the terminal starts to establish a first USB connection according to a first USB standard, or after the terminal establishes the first USB connection according to the first USB standard, judging whether a Wi-Fi module of the terminal is in a working state, if not, namely the Wi-Fi module of the terminal is not in the working state, turning to step 402; if yes, that is, the Wi-Fi module of the terminal is in a working state, go to step 403.

Step 403: judging whether the working frequency band supported by the Wi-Fi module of the terminal at least comprises a 5GHz frequency band, if so, turning to step 404; otherwise go to step 405.

Step 404: USB3.1 GEN1 is determined as the second USB standard.

Optionally, when the second USB standard is USB3.1 GEN1, the terminal determines whether the Wi-Fi module of the terminal operates at 2.4Ghz, if so, the current operating frequency band of the Wi-Fi module needs to be adjusted to a 5Ghz frequency band, otherwise, the Wi-Fi module continues to operate at the 5Ghz frequency band.

Step 405: the USB2.0 FS is determined as the second USB standard.

Namely, when the working frequency band supported by the Wi-Fi module of the terminal is only the 2.4GHz frequency band, the USB2.0 FS is determined as the second USB standard

Step 406: judging whether the first USB standard is the same as the second USB standard, if not, namely the first USB standard is different from the second USB standard, turning to step 407; otherwise, namely the first USB standard is the same as the second USB standard, the whole process is ended.

Step 407: and establishing a second USB connection according to the second USB standard.

Step 501: after the terminal starts to establish a first USB connection according to a first USB standard, or after the terminal establishes the first USB connection according to the first USB standard, whether a Wi-Fi module of the terminal is in a working state is judged, if not, namely the Wi-Fi module of the terminal is not in the working state, the process goes to step 502; otherwise, the Wi-Fi module of the terminal is in the working state, and go to step 503.

Step 502: and accurately setting the USB standard with the highest transmission speed supported by the terminal as a second USB standard.

Step 503: judging whether the current working frequency band of the terminal is a 5GHz frequency band, if so, turning to step 504; otherwise go to step 505.

Step 504: USB3.1 GEN1 is determined as the second USB standard.

Step 505: the USB2.0 FS is determined as the second USB standard.

Step 506: and judging whether the first USB standard is the same as the second USB standard, if not, turning to the step 507, otherwise, ending the whole process.

Step 507: and establishing a second USB connection according to the second USB standard.

step 602: and when the terminal determines that the first USB standard is different from the second USB standard, establishing a second USB connection according to the second USB standard.

In step 601, when the terminal determines that the Wi-Fi module is in the off state, the USB standard with the highest transmission speed supported by the terminal is accurately defined as the second USB standard.

In order to avoid interference, in this embodiment of the present application, if the current working frequency band of the Wi-Fi module of the terminal is a 2.4GHz frequency band, and the working frequency band supported by the Wi-Fi module of the terminal at least includes a 5GHz frequency band, the terminal needs to adjust the working frequency band of the Wi-Fi module of the terminal to the 5GHz frequency band while establishing the second USB connection according to the USB3.1 GEN 1.

For other contents in step 601, reference may be made to the description in step 301, and details are not repeated here.

In step 602, after determining that the first USB standard is different from the second USB standard, the terminal re-establishes the second USB connection according to the second USB standard.

Correspondingly, when the terminal determines that the first USB standard is the same as the second USB standard, the terminal continues to work with the first USB connection as the standard.

Based on the above discussion, as shown in fig. 7, a flow chart of a USB connection establishment method provided in the third embodiment of the present application is schematically illustrated.

In the embodiment of the application, after the terminal determines that the USB cable is accessed to the USB interface, before the USB is established, the terminal may also determine the working state of the Wi-Fi module. When the terminal determines that the Wi-Fi module is in the working state, the terminal can directly determine the USB standard adopted in the final working process, so that the switching of USB connection is avoided, and the efficiency is improved. As described in detail below.

It should be noted that, other contents related to step 801 and step 802 may refer to the foregoing description, and are not described herein again.

According to the method provided by the embodiment of the application, before the terminal establishes the USB connection, when the Wi-Fi module of the terminal is determined to be in the working state, the USB standard can be determined according to the working frequency band supported by the Wi-Fi module and the first preset configuration strategy, or the USB standard can be determined according to the current working frequency band of the Wi-Fi module and the second preset configuration strategy, so that the required USB standard can be rapidly determined, and the USB connection can be established according to the determined USB standard. The determined USB standard is the USB standard which is not in conflict with the working frequency band of the Wi-Fi module according to the first preset configuration strategy and the second preset configuration strategy, so that interference of signals transmitted by the USB interface on Wi-Fi signals of the Wi-Fi module is reduced. Specifically, the method in the fourth embodiment may be executed when the terminal detects that the USB cable is inserted into the USB port, or further, determines that a USB cable connected to a peer device is inserted into the USB port of the terminal.
