Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for adjusting data transmission and a terminal device.
Background
Universal Serial Bus (USB) transmission is one of the main data transmission modes, and devices such as mobile terminals (mobile phones, PADs, notebook computers, etc.), routers, data cards, smart televisions, vehicle-mounted internet systems, etc. all adopt USB data transmission modes, thereby providing convenient data transmission experience for users. Meanwhile, the terminals or devices support a radio frequency communication function (support at least one of a global system for mobile communications GSM protocol, a code division multiple access CDMA protocol, a time division synchronous code division multiple access TD-SCDMA protocol, a wideband code division multiple access WCDMA protocol, and a long term evolution LTE protocol), so as to provide a network interconnection experience for users.
When the USB data transmission and the radio frequency communication scene exist at the same time, the USB data transmission can generate radio frequency band interference signals to interfere the radio frequency communication, the radio frequency communication quality is reduced, and meanwhile, the USB data transmission can also be interfered by the radio frequency communication signals to cause the USB data transmission rate to be reduced.
One existing method is to use USB2.0 transmission in a specific format, such as GSM protocol, CDMA protocol, TD-SCDMA protocol, or WCDMA protocol, because USB2.0 generates less radio frequency interference than USB 3.0. The transmission mode of USB3.0 is adopted for the strong signal of the LTE protocol, and the transmission mode of USB2.0 is adopted for the weak signal of the LTE protocol, so that the influence of the interference of the transmission mode of USB3.0 on the communication of the LTE protocol is avoided.
The above method has the following defects: both USB2.0 and USB3.0 data transmissions may cause interference to the radio frequency band, and even if the USB2.0 protocol is limited, it is still difficult to avoid the interference of the USB data transmissions to the radio frequency communications of GSM protocol, CDMA protocol, TD-SCDMA protocol, WCDMA protocol, and LTE protocol, but the degree of interference may be relatively reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a method for adjusting data transmission according to an embodiment of the present invention. The implementation of the method is described in detail below with reference to this figure.
It should be noted that the adjustment method for data transmission provided in the embodiment of the present invention is applied to a terminal device, and the terminal device supports simultaneous radio frequency data transmission and USU data transmission.
The method for adjusting data transmission may include the following steps:
step 101: and acquiring the strength information of the radio frequency signal under the conditions of USB data transmission and radio frequency data transmission of the universal serial bus.
The USB data transmission refers to establishing connection between the terminal device and another device (such as a computer) through a USB interface, and performing data transmission through the USB interface.
The radio frequency data transmission refers to radio frequency wireless communication transmission, for example, wireless communication transmission based on at least one of GSM protocol, CDMA protocol, TD-SCDMA protocol, WCDMA protocol and LTE protocol.
The radio frequency signal strength information includes: reference signal received power RSRP and/or signal to interference noise ratio SINR. The radio frequency signal strength information of the embodiment of the invention can reflect the communication state between the terminal equipment and the base station, and the higher radio frequency signal strength can ensure faster wireless communication transmission rate and throughput. Otherwise, the transmission rate and throughput of wireless communication may be reduced, which may affect the network experience of the terminal device.
And under the condition that the terminal equipment simultaneously performs USB data transmission and radio frequency data transmission, acquiring RSRP and/or SINR so as to judge whether the current radio frequency communication is greatly interfered by the USB communication according to the radio frequency signal strength information.
Step 102: and under the condition that the value corresponding to the radio frequency signal strength information is smaller than a first signal strength threshold value, adjusting the current USB driving capability grade until the value corresponding to the radio frequency signal strength information is larger than or equal to the first signal strength threshold value.
Here, when the value corresponding to the radio frequency signal strength information is smaller than the first signal strength threshold, it indicates that the rate of radio frequency data transmission is too low to meet the transmission requirement of the user, and the internet surfing experience of the user may be affected. Namely, the USB data transmission causes large interference to the radio frequency data transmission.
When the value corresponding to the radio frequency signal strength information is greater than or equal to the first signal strength threshold, it indicates that the rate of radio frequency data transmission can meet the transmission requirement of the user, that is, the rate of radio frequency data transmission is greater than the transmission rate required by the user, and specifically, the difference between the number of radio frequency data transmissions and the transmission rate required by the user is the first value.
In addition, in the embodiment of the present invention, the USB driving capability level may be divided into different levels according to the signal voltage amplitude, the driving current intensity, the time length between the rising edge and the falling edge, and the like.
In the embodiment of the invention, under the condition of carrying out USB data transmission and radio frequency data transmission on a universal serial bus, the strength information of a radio frequency signal is obtained; and under the condition that the value corresponding to the radio frequency signal strength information is smaller than a first signal strength threshold value, adjusting the current USB driving capability grade until the value corresponding to the radio frequency signal strength information is larger than or equal to the first signal strength threshold value. Compared with the prior art, the embodiment of the invention can further reduce the influence of USB data transmission on radio frequency data transmission by adjusting the driving capability grade of the USB, ensure certain radio frequency communication signal intensity, further ensure the transmission rate of the radio frequency communication and meet the transmission requirement of a user.
Further, the acquiring the radio frequency signal strength information includes:
acquiring target radio frequency communication information; acquiring a target USB driving capacity grade corresponding to the target radio frequency communication information; adjusting the USB driving capability level to the target USB driving capability level; and after the interval preset time, acquiring the radio frequency signal intensity information.
In this embodiment of the present invention, the target radio frequency information may include at least one of a communication system, a communication frequency band, and a communication channel. The communication indication comprises: at least one of GSM, CDMA, TD-SCDMA, and WCDMA.
In addition, the embodiment of the invention is pre-stored with the corresponding relation between the target radio frequency communication information and the USU driving capability level. After the target radio frequency communication information is obtained, according to the corresponding relation, the target USB driving capacity grade corresponding to the target radio frequency communication information is found, the USB driving capacity grade is adjusted to be the target USB driving capacity grade, and finally, after the preset time (target radio frequency communication information refreshing) is separated, the radio frequency signal strength information is obtained. At this time, the acquired rf signal strength information is the rf signal strength information when USB data transmission is performed at the target USB driving capability level.
Further, when the value corresponding to the rf signal strength information is smaller than the first signal strength threshold, adjusting the current USB driving capability level until the value corresponding to the rf signal strength information is greater than or equal to the first signal strength threshold, including:
reducing the driving capability level of the USB under the condition that the numerical value corresponding to the radio frequency signal strength information is smaller than a first signal strength threshold value; after a preset time interval, re-acquiring the radio frequency signal intensity information; and under the condition that the value corresponding to the radio frequency signal strength information obtained again is smaller than the first signal strength threshold value, continuously reducing the USB driving capacity level until the value corresponding to the radio frequency signal strength information is larger than or equal to the first signal strength threshold value.
Specifically, the method for reducing the driving capability level of the USB comprises at least one of reducing the voltage amplitude of the signal, reducing the driving current intensity and increasing the time between the rising edge and the falling edge of the signal.
Here, when the value corresponding to the radio frequency signal strength information is smaller than the first signal strength threshold, the USB driving capability level is reduced according to a predetermined value, for example, the predetermined value is 1, the current USB driving capability level is reduced by 1 level, from L level to L-1 level, and after a preset time after the current USB driving capability level is reduced to L-1 level, the radio frequency signal strength information is obtained again, and whether the value corresponding to the radio frequency signal strength information is smaller than the first signal strength threshold is continuously determined, if so, the value corresponding to the radio frequency signal strength information is reduced by 1 level, that is, the value is adjusted to L-2 level, and then the step of obtaining the radio frequency signal strength signal is continuously performed, so as to circulate until the value corresponding to the obtained radio frequency signal strength information is greater than or equal to the first signal strength threshold.
Wherein, the lower the USB driving capability level, the lower the interference to the radio frequency communication, and L is a positive number.
Further, after the obtaining the radio frequency signal strength information, the method further includes:
when the value corresponding to the radio frequency signal strength information is greater than or equal to a first signal strength threshold value and greater than a second signal strength threshold value, raising the USB driving capability level, wherein the second signal strength threshold value is greater than the first signal strength threshold value;
after a preset time interval, re-acquiring the radio frequency signal intensity information;
and under the condition that the value corresponding to the radio frequency signal strength information is smaller than a first signal strength threshold value, adjusting the current USB driving capability grade to enable the value corresponding to the radio frequency signal strength information to be larger than or equal to the first signal strength threshold value and smaller than or equal to a second signal strength threshold value.
In the embodiment of the present invention, when the value corresponding to the rf signal strength information is greater than or equal to the second signal strength threshold, it indicates that the rate of the rf data transmission can completely meet the transmission requirement of the user, and there is a certain margin, that is, the difference between the rate of the rf data transmission and the transmission rate required by the user is the second value, and the second value is greater than the first value, at this time, the driving capability level of the USB transmission data signal can be properly increased, so as to improve the anti-interference capability of the USB transmission data signal. That is, when the value corresponding to the rf signal strength information is greater than the second signal strength threshold, the USB driving capability level is raised, for example, by one level, and after the USB driving capability level is raised by one level and a preset time interval is elapsed, the rf signal strength information is obtained again, and when the value corresponding to the rf signal strength information is less than the first signal strength threshold, the current USB driving capability level is adjusted, so that the value corresponding to the rf signal strength information is maintained between the first signal strength threshold and the second signal strength threshold.
The method for increasing the driving capability level of the USB comprises at least one of increasing the voltage amplitude of the signal and increasing the driving current intensity.
In the embodiment of the invention, the USB driving capability grade can be adjusted to a larger extent according to the corresponding relation between the pre-stored target radio frequency communication information and the USU driving capability grade, and then the USB driving capability grade is finely adjusted according to the relation between the numerical value corresponding to the radio frequency signal strength information and the first signal strength threshold value and the second signal strength threshold value, so that the anti-interference capability of the USB transmission data signal is ensured on the premise of greatly reducing the interference of the USB data transmission on the radio frequency communication data transmission.
Further, after the obtaining the radio frequency signal strength information, the method further includes:
and under the condition that the numerical value corresponding to the radio frequency signal strength information is greater than or equal to a first signal strength threshold value and is less than or equal to a second signal strength threshold value, storing and updating the corresponding relation between the current USB driving capability grade and the target radio frequency communication information, wherein the second signal strength threshold value is greater than the first signal strength threshold value.
Here, when the value corresponding to the rf signal strength information is greater than or equal to the first signal strength threshold and less than or equal to the second signal strength threshold, the corresponding relationship between the current USB driving capability level and the target rf communication information is saved and updated, that is, the corresponding relationship between the target rf communication information and the USB driving capability level stored in advance is updated.
