Description

Universal serial bus USB working mode processing method and device

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for processing a working mode of a universal serial bus USB.

Background technique

The USB 3.0 Promoter Group, which consists of IT giants such as Intel, announced on November 18, 2008 that the next-generation USB 3.0 standard that the organization is responsible for has been officially completed and released. The new specification provides ten times the transfer speed of USB 2.0 and higher energy efficiency, and can be widely used in personal computers (Personal Computer, PC for short) peripheral terminals and consumer electronics. USB 3.0 will be referred to as "USB Super Speed" in actual terminal applications, conforming to previous USB1.1Full Speed and USB 2.0 High Speed. Commercial controllers supporting the new specification were launched in the second half of 2009, and consumer products were launched in 2010.

Currently, the actual transfer rate of USB 3.0 is approximately 3.2 Gbps (ie, 320 MB/s). The theoretical maximum rate is 5.0 Gbps (ie 500 MB/s). USB 3.0 has a backward compatibility standard, is compatible with USB1.1 and USB2.0 standards, and has the ease of use and plug-and-play functionality of the traditional Universal Serial Bus (USB) technology. The goal of USB 3.0 technology is to launch products that are 10 times faster than USB 2.0, using the same architecture as wired USB. In addition to optimizing the USB 3.0 specification for lower power consumption and higher protocol efficiency, USB 3.0 ports and cables enable backward compatibility and support for future fiber transport. For backward compatibility with version 2.0, USB 3.0 features a 9-pin design with four pins and USB 2.0 in the same shape and definition, and the other five are specifically for USB 3.0.

When used, USB3.0 will add about 20dB of noise in the 2.4G band, causing radio frequency interference in the 2.4GHz Industrial Scientific Medical (ISM) band. This kind of interference will reduce the sensitivity of wireless reception, and thus reduce the range of reception, which is enough to affect the normal use of interfering wireless terminals (wireless network cards, wireless mice, wireless headsets, etc.). In fact, the spread spectrum processing of USB 3.0 causes its spectrum to cover from 0 Hz to 5 GHz. As measured by Intel, the interference power decreases with frequency, which is about -60dBm in the 2.4G band and -90dBm in the 5G band. When the RF receiver in this band is placed closer to the USB 3.0 device or connector, the interference situation becomes more apparent.

Since the noise generated by USB 3.0 high-frequency communication is a kind of broadband noise, it cannot be eliminated by filtering, and it just falls within the commonly used 2.4-2.5 GHz frequency range. Intel's proposed solution is to shield the USB 3.0 connector and peripheral devices, and the more complete and effective the better. In addition, the antenna should be placed as far as possible from the USB 3.0 connector and device. Therefore, it can be known that the interference shielding method in the related art needs to shield the USB 3.0 connector and peripheral devices, that is, additional devices need to be added for interference shielding, and devices that perform interference shielding can only interfere with specific frequency bands. Therefore, the interference shielding cost is high, and the interference shielding device is low in availability.

In view of the above problems, an effective solution has not been proposed in the related art.

Among them, USB3.0 mode means that the terminal hardware and software support USB3.0 specification, and the maximum transmission bandwidth of the terminal in high frequency (2.4G-2.5GHz) transmission is up to 5.0Gbps (500MB/s). The USB2.0 mode indicates that the terminal hardware and software support the USB3.0 specification, but only the low-frequency transmission has a maximum transmission bandwidth of 480 Mbps (ie, 60 MB/s), so the USB 2.0 mode does not interfere with the Wi-Fi 2.4G band.

Step 206: Determine whether the Wi-Fi 2.4G frequency band has client access. If not, keep the USB module default working mode. If yes, go to step 208.

If the client only supports the 2.4G band, the client uses the 2.4G band of the terminal Wi-Fi to access.

Step 208: Determine whether the terminal USB module performs high frequency data transmission. If not, the default operation mode of the USB module is maintained. If yes, step 210 is performed.

The U.S. USB module can determine whether the current terminal USB module performs high frequency data transmission by determining whether the external USB device supports the USB 3.0 working mode and whether the data is transmitted with the terminal USB module.

Step 210: Set the terminal USB module to work in the USB 2.0 mode.

Wherein, if the terminal USB module does not have high frequency data transmission, the terminal USB module is set to work in the USB3.0 mode.

In the specific embodiment of the present invention, a method for suppressing the radio interference of the USB 3.0 is also provided. In this embodiment, the terminal can only support the 2.4G frequency band and does not support the 5G frequency band. The following describes the manner in this embodiment. :

Step 1: After the terminal is powered on, the Wi-Fi module loads the 2.4G band by default.

Step 2: The USB module works in USB3.0 mode by default.

Step 3: Determine whether the Wi-Fi 2.4G band has client access. If not, keep the default operation mode of the USB module. If yes, go to step 4.

Step 4: Determine whether the terminal USB module performs high-frequency data transmission. If not, keep the default operation mode of the USB module. If yes, go to step 5.

Optionally, whether the current terminal USB module performs high frequency data transmission may be determined by determining whether the external USB device supports the USB 3.0 working mode and whether the data is performed with the terminal USB module.

Step 5: Set the terminal USB module to work in USB2.0 mode.
