Description

Universal serial bus interface mode control method and device, and storage medium

Technical field

The present invention relates to the field of communications technologies, and in particular, to a universal serial bus interface mode control method and apparatus, and a storage medium.

Background technique

The Universal Serial Bus (USB) is an external bus standard that regulates the connection and communication between computers and external devices. The USB standard has evolved over the years and is now available in multiple versions, such as USB 1.0, USB 2.0 and USB 3.0. Among them, USB3.0 is a new USB specification released by Intel and industry leaders. USB3.0 provides ten times the transmission speed and higher energy efficiency of USB2.0, and can be widely used for high-speed transmission of various terminal devices; and while achieving lower power consumption, USB3.0 has a higher protocol. Efficiency; USB3.0 also has backward compatibility, backward compatible with USB2.0/1.0 and other versions. Therefore, in the digital age, high-speed performance and reliable interconnection are required to achieve huge data volume transmission. USB3.0 can well cope with this challenge, and USB3.0 can also improve the charging efficiency of terminal devices, thereby enhancing users. The degree of experience. At present, the USB3.0 interface is mainly applied to terminal devices such as a personal computer (Personal Computer, PC), a mobile hard disk, a USB flash drive, and a card reader.

However, while USB 3.0 brings the above advantages, there are also corresponding problems. For example, the use of USB 3.0 will affect the over-the-air (OTA) performance of the terminal device, that is, affect the overall radiation performance of the device. The OTA parameters embodying the OTA performance are mainly divided into two categories: receiving parameters and transmitting parameters. The transmission parameters include Total Radiated Power (TRP), which is obtained by averaging and averaging the transmission power of the entire radiation sphere; Near Horizon Partial Radiated Power (NHPRP), which reflects The transmit power of the antenna near the H-plane of the device. Receiving parameters including isotropic sensitivity (Total Isotropic Sensitivity, TIS), this parameter is reflected in the receiving sensitivity of the entire radiation spherical device; Near Horizon Partial Isotropic Sensitivity (NHPIS) This parameter reflects the receiving sensitivity of the antenna near the H-plane. Case.

Specifically, as shown in FIG. 1A, FIG. 1A shows that in the case that the USB interface of the data card does not transmit data, the relevant standard specifies the TIS parameter standard value that the data card should reach for the wireless signals of different frequency bands (ie, FIG. 1A). The TIS parameter standard value specified in the relevant standard), the TIS parameter value of the data card obtained in the actual OTA test and working in the USB3.0 interface mode (ie, the USB3.0TIS parameter value in FIG. 1A), obtained by the actual OTA test. The value of the TIS parameter of the data card operating in the USB 2.0 interface mode (ie, the USB 2.0 TIS parameter value in FIG. 1A), and the difference between the TIS parameter standard value and the TIS parameter value obtained by the test. Also shown in FIG. 1A is the first difference, that is, the difference between the TIS parameter standard value specified by the relevant standard and the USB 2.0 TIS parameter value; and the second difference, that is, the TIS parameter standard value specified by the relevant standard and The difference between the USB3.0TIS parameter values.

Among them, the data card refers to a terminal device applied to a computer and using a mobile communication technology to access the Internet. Specifically, the data card is provided with a Subscriber Identity Module (SIM), that is, a SIM card, and the data card is connected to the Internet through the SIM card. The units of the TIS parameter standard value, the USB2.0 TIS parameter value, and the USB 3.0 TIS parameter value specified by the relevant standard shown in FIG. 1A are all decibels (dB). The above OTA test tools are: a data card with a USB 2.0 interface + a notebook computer, a data card with a USB 3.0 interface + a notebook computer; the above OTA test dark room is: a 3D dark room for OTA testing. According to the TIS parameter value shown in FIG. 1A, in the free space 3D darkroom, and the USB interface does not transmit data, the TIS of the data card operating in the USB3.0 interface mode is compared to the USB 2.0 interface. The TIS of the data card of the mode decreased by 4.5 to 9.7 dB, which did not meet the TIS standard stipulated by the relevant standards; and in the wireless signals of different frequency bands tested above, the TIS decreased in the Long Term Evolution Band 5 (LTE Band 5). Most notably, the LTE Band 5 bandwidth (BW) is 10 MHz. As can be seen from the above description, the use of the USB3.0 interface mode affects the terminal design. The performance of the receiving wireless signal is such that the OTA parameter value of the terminal device using the USB3.0 interface mode does not comply with the relevant standard.

According to the information released by Intel, the spread spectrum processing of USB3.0 causes its spectrum to cover from 0Hz to 5GHz. After measurement, when the USB interface of the terminal device works in USB3.0 interface mode, the terminal device will Noise is added to the wireless signal in the 0 to 5 GHz band, and about 20 dB of noise is added to the wireless signal in the 2.4 GHz band, causing radio frequency interference to the wireless signal in the 2.4 GHz band, which reduces the receiving sensitivity of the terminal device, that is, Reduce the TIS of the terminal device, thereby reducing the receiving range of the terminal device, which is enough to affect the use of 2.4GHz wireless signals of the terminal device, such as the use of 2.4GHz WiFi function, the use of 2.4GHz Bluetooth function, etc.; but the interference power of USB3.0 It will decrease with the increase of the signal frequency. For example, the interference noise in the 2.4 GHz band is about 20 dB higher than the interference noise in the 5 GHz band. As can be seen from the above description, the use of the USB 3.0 interface mode affects the performance of the terminal device receiving the 2.4 GHz wireless signal, and the terminal device using the USB 3.0 interface mode may not be able to use the 2.4 GHz wireless signal.

The prior art solution to the above problem is generally to increase the absolute distance between the antenna of the terminal device and the USB 3.0 interface, or to shield the USB 3.0 interface of the terminal device to reduce the interference. However, the above method is only applicable to some terminal devices, such as PCs, which are relatively large in size, and is not applicable to terminal devices of relatively small size such as mobile phones.

In summary, the use of the USB 3.0 interface mode affects the OTA performance of the terminal device, and the prior art can only solve the above problems of some terminal devices and reduce the user experience.

The present invention will be further described in detail below with reference to the drawings and specific embodiments.

FIG. 1B is a schematic flowchart of a method for controlling a universal serial bus interface mode according to an embodiment of the present invention. As shown in FIG. 1B, the method includes:

Step 101: Acquire a determination result of whether the wireless working state of the terminal device meets the preset condition.

It should be noted that the wireless working state of the terminal device refers to the working state of the terminal device when the terminal device uses the wireless signal.

Specifically, the implementation manner of this step may be mode one, mode two, or mode three.

In the first step, the step of the terminal device may be: when the terminal device uses the mobile network signal, the terminal device acquires a determination result that the signal receiving rate of the terminal device is greater than a preset threshold.

It should be noted that, in the first method, the wireless working state of the terminal device is specifically a rate state in which the terminal device currently receives the mobile network signal when the terminal device uses the mobile network signal. The signal receiving rate of the terminal device refers to a rate at which the terminal device receives the mobile network signal.

Specifically, when the terminal device uses the mobile network signal, the terminal device obtains a step of determining whether the signal receiving rate of the terminal device is greater than a preset threshold, and the implementation process may be: When the terminal device uses the mobile network signal to perform the data service, the terminal device determines whether the signal receiving rate is greater than a preset threshold; the terminal device obtains the determination result, and the determination result is that the signal receiving rate of the terminal device is not greater than a preset threshold, or is a terminal. The signal receiving rate of the device is greater than a preset threshold. That is, when the terminal device uses the mobile network signal, the terminal device directly determines whether the signal receiving rate is greater than a preset threshold.

Specifically, when the terminal device uses the mobile network signal, the terminal device obtains a determination result that the terminal device signal receiving rate is greater than a preset threshold, and the implementation process may be: when the terminal device uses the mobile network signal to perform data service, The terminal device periodically determines whether it operates in a carrier aggregation (CA) mode; when the terminal device does not work in the carrier aggregation mode, that is, when the terminal device works in the single carrier mode, the terminal device determines that the signal receiving rate is not greater than the pre- The threshold value is set; when the terminal device works in the carrier aggregation mode, the terminal device determines whether the signal receiving rate is greater than a preset threshold; the terminal device obtains the determination result, and the determination result is that the signal receiving rate of the terminal device is not greater than a preset threshold, or The signal receiving rate of the terminal device is greater than a preset threshold. That is, the terminal device does not directly determine whether the signal receiving rate is greater than a preset threshold, but first determines whether it works in the carrier aggregation mode, so that the terminal device needs to determine the signal receiving rate when the terminal device is not working in the carrier aggregation mode. Whether it is greater than the preset threshold.

If the terminal device is a data card, the foregoing process may be: when the data card uses the mobile network signal to provide the user with the Internet service, the data card periodically determines whether it works in the carrier aggregation mode; when the data card does not work in the carrier aggregation mode, When the data card works in the single carrier mode, the data card determines that the signal receiving rate is not greater than a preset threshold; when the data card works in the carrier aggregation mode, the data card determines whether the signal receiving rate is greater than a preset threshold; the data card obtains the judgment result. The judgment result is that the signal receiving rate of the data card is not greater than a preset threshold, or the signal receiving rate of the data card is greater than a preset threshold. Of course, the terminal device can also be other devices, such as a mobile phone. The following process is specifically described by taking a data card as an example.

It should be noted that the terminal device can determine whether it works in the carrier aggregation mode by reading the carrier mode related parameters stored therein. The terminal device can determine whether the signal receiving rate is greater than a preset threshold by reading a mobile network signal receiving rate related parameter stored therein.

The preset threshold may be set according to a maximum data transmission rate of the second USB interface mode. The second USB interface mode may refer to an interface mode of USB2.0 and below, such as a USB2.0 interface mode or a USB1.0 interface mode. In this embodiment, it may specifically be a USB2.0 interface mode. If the USB interface of the terminal device works in the USB2.0 interface mode and the maximum data transmission rate of the USB interface is 320 Mbps, the preset threshold can be set to 320 Mbps. Therefore, the terminal device can know whether the current signal receiving rate is greater than the maximum data transmission rate of the USB2.0 interface mode.

The mobile network signal may be a mobile network signal using a second generation, a third generation, a fourth generation or more mobile communication technologies, that is, the mobile network signal may be a mobile network such as 2G (Generation), 3G or 4G. signal.

In the second manner, in this step, when the terminal device uses the wireless signal, the terminal device acquires whether the working frequency of the wireless signal of the terminal device is the determination result of the preset frequency band.

It should be noted that, in the second mode, the wireless working state of the terminal device is specifically a frequency state of a wireless signal currently received or transmitted by the terminal device when the terminal device uses the wireless signal. The wireless signal operating frequency of the terminal device refers to the frequency of the wireless signal currently received or transmitted by the terminal device.

Specifically, when the terminal device uses the wireless signal, the terminal device obtains the step of determining whether the working frequency of the wireless signal of the terminal device is the preset frequency band, and the implementation manner may be the mode I or the mode II.

In the mode 1, when the terminal device uses the wireless signal, the terminal device acquires the terminal device. Whether the working frequency of the wireless signal is the judgment result of the preset frequency band, when the terminal device accesses the network by using the wireless fidelity (WiFi) signal, the terminal device acquires whether the WiFi signal works in the first preset frequency band. critical result.

Specifically, when the terminal device accesses the network by using the WiFi signal, the terminal device obtains a determination result that the WiFi signal works in the first preset frequency band, and may include: when the terminal device uses the wired network through the WiFi signal, the terminal device The terminal device determines whether the WiFi signal works in the first preset frequency band; the terminal device obtains the determination result, and the determination result is that the WiFi signal of the terminal device works in the first preset frequency band, or the WiFi signal of the terminal device does not work in the first preset Set the frequency band. For example, when the mobile phone uses the wired network through the WiFi signal, the mobile phone periodically determines whether the WiFi signal works at 2.4 GHz; the mobile phone obtains the judgment result, and the judgment result is that the WiFi signal of the mobile phone works at 2.4 GHz, or the WiFi signal of the mobile phone does not work. 2.4GHz.

It should be noted that the terminal device may determine whether the WiFi signal works in the first preset frequency band by reading a WiFi signal related parameter stored therein.

The first preset frequency band may be set according to a strongest interference frequency band of the first USB interface mode. The first USB interface mode may refer to an interface mode of USB 3.0 and above, such as a USB 3.0 interface mode or a USB 3.1 interface mode. In this embodiment, it may specifically be a USB3.0 interface mode. If the first USB interface mode is USB3.0 interface mode, and the USB interface of the terminal device works in the USB3.0 interface mode through actual measurement, the wireless signal interference to the 2.4 GHz band is the strongest, thereby affecting the terminal device 2.4 GHz wireless. For the use of the signal, the first preset frequency band can be set to 2.4 GHz. Therefore, the terminal device can learn whether the WiFi signal works in the strongest interference frequency band of the first USB interface mode by using the step 101.

In the mode II, when the terminal device uses the wireless signal, the terminal device obtains the determination result of whether the working frequency of the wireless signal of the terminal device is the preset frequency band, and may be, after the terminal device registers with the mobile network signal, the terminal device acquires the mobile terminal. Whether the network signal works in the second preset frequency band.

Specifically, after the terminal device registers with the mobile network signal, the terminal device obtains a determination result of whether the mobile network signal works in the second preset frequency band, and the implementation process may be: after the terminal device registers with the mobile network signal, The terminal device determines whether the mobile network signal works in the second preset frequency band; the terminal device obtains the determination result, and the determination result is that the mobile network signal of the terminal device works in the second preset frequency band, or the mobile network signal of the terminal device does not work. In the second preset frequency band. That is, after the terminal device registers with the mobile network signal, the terminal device directly determines whether the mobile network signal works in the second preset frequency band.

Specifically, after the terminal device registers with the mobile network signal, the terminal device obtains a determination result of whether the mobile network signal works in the second preset frequency band, and the implementation process may be, after the terminal device registers with the mobile network signal, The terminal device periodically monitors whether the registered mobile network signal belongs to the mobile network signal of 3G or above; when the registered mobile network signal does not belong to the mobile network signal of 3G or above, the terminal device determines that the mobile network signal does not work in the second The preset frequency band; when the registered mobile network signal belongs to the mobile network signal of 3G or above, the terminal device determines whether the mobile network signal works in the second preset frequency band; the terminal device obtains the determination result, and the determination result is the movement of the terminal device The network signal works in the second preset frequency band, or the mobile network signal of the terminal device does not work in the second preset frequency band.

For example, after the terminal device registers with the mobile network signal, the terminal device periodically monitors whether the registered mobile network signal belongs to the mobile network signal of 3G or above; when the registered mobile network signal does not belong to the mobile network signal of 3G or above, the terminal The device determines that its mobile network signal is not working in the 2.3 GHz to 2.5 GHz frequency band; when the registered mobile network signal belongs to the mobile network signal of 3G and above, the terminal device determines whether its mobile network signal operates in the 2.3 GHz to 2.5 GHz frequency band; The device obtains a judgment result, which is that the mobile network signal of the terminal device operates in the 2.3 GHz to 2.5 GHz frequency band, or the mobile network signal of the terminal device does not operate in the 2.3 GHz to 2.5 GHz frequency band.

The second preset frequency band may be according to a strongest interference frequency band of the first USB interface mode. And the mobile network signal working frequency band is set. If the first USB interface mode is USB3.0 interface mode, and the terminal device works in the USB3.0 interface mode through actual measurement, the wireless signal interference in the 2.4 GHz band is the strongest, thereby affecting the use of the 2.4 GHz wireless signal of the terminal device. And the working frequency band of the mobile network signal includes: 2.3GHz to 2.5GHz frequency band, the working frequency band covers 2.4GHz, then the second preset frequency band can be set to 2.3GHz to 2.5GHz. Therefore, the terminal device can know whether the working frequency band of the mobile network signal covers the strongest interference frequency band of the first USB interface mode.

It should be noted that, the method for obtaining, by the terminal device, whether the working frequency of the wireless signal of the terminal device is the determination result of the preset frequency band, in addition to the mode I or the mode II described above, or other manners, such as The terminal device obtains whether its Bluetooth signal operating frequency is 2.4 GHz.

The third method may include: when the terminal device uses the mobile network signal, the terminal device acquires a determination result that the signal receiving rate of the terminal device is greater than a preset threshold; and when the determining result is that the signal receiving rate is greater than a preset threshold, the terminal device Obtaining a determination result of whether the mobile network signal of the terminal device works in the second preset frequency band.

The setting process of the preset threshold is the same as the setting process of the preset threshold in the mode 1. The setting process of the second preset frequency band described herein is the same as the setting process of the second preset frequency band in the second mode. Therefore, the terminal device can learn whether the signal receiving rate is greater than the maximum data transmission rate of the second USB interface mode and whether the working frequency band of the mobile network signal covers the strongest interference frequency band of the first USB interface mode.

Specifically, the terminal device obtains a result that the signal receiving rate of the terminal device is not greater than a preset threshold; or the signal receiving rate of the terminal device is greater than a preset threshold, and the mobile network signal does not work in the second preset. The frequency band; or, the signal receiving rate of the terminal device is greater than a preset threshold, and the mobile network signal operates in the second preset frequency band.

Step 102: Control the USB interface of the terminal device to work on the first USB interface according to the determination result. Port mode or second USB interface mode.

Specifically, the step may be that the terminal device controls the USB interface of the terminal device to operate in the first USB interface mode or the second USB interface mode according to the determination result obtained in step 101. In this way, according to the wireless working state of the terminal device, the working mode of the terminal device USB interface is controlled, and the influence of the use of the high-speed USB interface mode on the performance of the terminal device OTA can be realized, so that the OTA parameters of the terminal device configured with the high-speed USB interface comply with relevant standards. And the terminal device configured with the high-speed USB interface can use the 2.4 GHz wireless signal, thereby improving the user experience.

Specifically, the implementation manner of this step may be the first mode, the second mode, the third mode, or the fourth mode.

In the first step, the step may include: when the judgment result is that the signal receiving rate of the terminal device is greater than a preset threshold, the terminal device controls the USB interface of the terminal device to work in the first USB interface mode; and the result of the determination is the signal receiving rate of the terminal device. When the threshold is not greater than the preset threshold, the terminal device controls the USB interface of the terminal device to work in the second USB interface mode. That is, when the maximum data transmission rate of the second USB interface mode does not satisfy the signal receiving rate of the terminal device, the terminal device controls its USB interface to operate in the first USB interface mode; the maximum data transmission rate in the second USB interface mode satisfies When the terminal device receives the signal, the terminal device controls its USB interface to operate in the second USB interface mode. Therefore, the terminal device can be in the high-speed USB interface mode in real time, and the influence of the use of the high-speed USB interface mode on the performance of the terminal device OTA is controlled, so that the OTA parameters of the terminal device configured with the high-speed USB interface comply with relevant standards; The use of the high-speed USB interface mode by the terminal device and the requirements of the relevant standard for the OTA parameters of the terminal device.

For example, in the case of a data card, the maximum data transmission rate in the USB2.0 interface mode does not satisfy the number. According to the signal receiving rate of the card, the data card can control its USB interface to work in the USB3.0 interface mode; when the maximum data transmission rate in the USB2.0 interface mode satisfies the signal receiving rate of the data card, the data card can be controlled. Its USB interface works in USB2.0 interface mode. Therefore, the data card can be in the USB3.0 interface mode in real time, and the influence of the use of the USB3.0 interface mode on the performance of the data card OTA is controlled, so that the OTA parameters of the data card configured with the USB3.0 interface comply with relevant standards; To a certain extent, the use of the data card to the USB3.0 interface mode and the requirements of the relevant standards for the OTA parameters of the terminal device are taken into account.

In the second method, the step may include: when the judgment result is that the WiFi signal of the terminal device is not working in the first preset frequency band, the terminal device controls the USB interface of the terminal device to work in the first USB interface mode; When the WiFi signal works in the first preset frequency band, the terminal device controls the USB interface of the terminal device to work in the second USB interface mode. That is, when the WiFi signal of the terminal device does not work in the strongest interference band of the first USB interface mode, the terminal device controls its USB interface to work in the first USB interface mode; the WiFi signal of the terminal device works in the first USB interface mode. In the strongest interference band, the terminal device controls its USB interface to work in the second USB interface mode. Therefore, the terminal device can be in the high-speed USB interface mode in real time, and the influence of the use of the high-speed USB interface mode on the performance of the terminal device OTA is controlled, so that the terminal device configured with the high-speed USB interface can use the WiFi signal of the 2.4 GHz band; The use of the terminal device for the high-speed USB interface mode and the WiFi signal for the 2.4 GHz band is taken into account.

For example, in the case of a mobile phone, when the WiFi signal of the mobile phone does not work in the 2.4 GHz band, the mobile phone can control its USB interface to work in the USB 3.0 interface mode; when the WiFi signal of the mobile phone works in the 2.4 GHz band, the mobile phone can be controlled. Its USB interface works in USB2.0 interface mode. Therefore, the mobile phone can be in the USB3.0 interface mode in real time, and the influence of the use of the USB3.0 interface mode on the performance of the mobile phone OTA is controlled, so that the mobile phone configured with the USB3.0 interface can use the WiFi signal of the 2.4 GHz band; Take care of the phone to USB3.0 interface mode and Use of WiFi signals in the 2.4 GHz band.

In the third method, the step may include: when the mobile network signal of the terminal device is not working in the second preset frequency band, the terminal device controls the USB interface of the terminal device to work in the first USB interface mode; When the mobile network signal works in the second preset frequency band, the terminal device controls the USB interface of the terminal device to work in the second USB interface mode. That is, when the working frequency band of the mobile network signal of the terminal device does not cover the strongest interference frequency band of the first USB interface mode, the terminal device controls its USB interface to work in the first USB interface mode; the working frequency band of the mobile network signal of the terminal device When covering the strongest interference band of the first USB interface mode, the terminal device controls its USB interface to operate in the second USB interface mode. Therefore, the terminal device can be in the high-speed USB interface mode in real time, and control the influence of the use of the high-speed USB interface mode on the performance of the terminal device OTA, so that the terminal device configured with the high-speed USB interface can use the mobile network signal of the 2.4 GHz band; To a certain extent, the use of terminal equipment for high-speed USB interface mode and mobile network signals for the 2.4 GHz band is considered.
