Wherein, the electronic device may be a mobile terminal. Wherein, the mobile terminal may be a smart phone, a tablet, a vehicle-mounted terminal, a smart wearable device, or the like.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a data transmission method provided by an embodiment of the present application. As shown in FIG. 1, a process of the data transmission method provided by the embodiment of the present application may be as follows:

In 110, when the terminal performs data transmission through the wired data transmission interface, call detection is performed on the terminal.

The following description will be given by taking an example where the execution body of the data transmission method is a data transmission device. Wherein, the data transmission device can be integrated in the mobile terminal. Specifically, the data transmission device may be integrated in an application processor (Application Processor, AP) of the mobile terminal.

Among them, driven by the needs of improving the resolution and storage performance of consumer electronic terminals, users hope to obtain faster and more stable transmission performance when connecting electronic terminals to Internet resources, so as to achieve the download, storage and sharing of resources. Purpose. In this context, the USB3.0 standard interface came into being. The USB3.0 standard interface can not only greatly improve the efficiency of data transmission, but also has the advantages of convenient transmission, support for hot swap, flexible connection and independent power supply, etc., and is more and more favored by users.

However, USB3.0 uses spread spectrum technology, which brings wide-band noise of 0-5GHz while it transmits signals at high speed. Especially in the frequency range of 2.4GHz to 2.5GHz, there is about 20dB of noise, which is enough to interfere with the normal use of wireless devices (such as wireless network cards, wireless mice, and wireless earphones). Similarly, the anti-interference performance of USB3.0 is also poor, so the grounding measures of the connector and the printed circuit board (Printed Circuit Board, PCB)/middle frame are very important. When the antenna near the connector makes a high-power call (such as the Global System for Mobile Communications (GSM)), the main wave energy radiated by the antenna will interfere with the USB3.0 transmission, causing the USB3.0 transmission to be interrupted. flow problem. In order to solve the problem that USB3.0 data transmission is interrupted and unstable data transmission caused by a call in the above situation, the present application provides a data transmission method, which can effectively improve the stability of USB3.0 during data transmission.

Specifically, when the wired data transmission interface of the terminal is connected to USB 3.0 and receives an instruction for data transmission through the connected USB 3.0, the terminal may first perform call detection to determine whether the terminal is in a call state.

In some embodiments, when the terminal performs data transmission through the wired data transmission interface, performing call detection on the terminal, including:

A. When the terminal transmits data through the wired data transmission interface, the transmission rate of the data transmission is detected;

B. When the transmission rate is lower than the target rate value, perform call detection on the terminal.

Among them, in the embodiment of the present application, when the AP receives an instruction to connect the USB3.0 through the wired data transmission interface for data transmission, it may not need to directly perform call detection on the terminal, but may first perform data transmission and transmit the current data. rate is detected. If it is detected that the current data transmission rate is greater than a preset target rate value, it can be determined that the current data transmission is not disturbed or the interference is small, and no further call control is required; on the contrary, if the current data transmission is detected When the transmission rate is less than the target rate value, it can be determined that the current data transmission is affected by signal interference, resulting in transmission drop or transmission interruption, and then the call process needs to be controlled to avoid signal interference of the current call to the data transmission. That is, when the transmission rate is less than the preset target rate value, call detection is performed on the terminal.

Wherein, in some embodiments, when the terminal performs data transmission through the wired data transmission interface, the call detection is performed on the terminal, including:

1. When it is detected that the terminal performs data transmission through the wired data transmission interface, the target broadcast is sent to the radio frequency modem of the terminal, and the target broadcast is used to control the radio frequency modem to obtain the call status information of the terminal;

2. Receive the call state information returned by the radio frequency modem, and perform call detection on the terminal based on the call state information.

Wherein, in this embodiment of the present application, the call detection is performed on the terminal, and specifically, the call detection may be performed through a radio frequency modem of the terminal, that is, a radio frequency modem. Wherein, the radio frequency modem may be integrated in a baseband processor (Baseband Processor, BP) of the terminal. In general, the terminal separates the AP and the BP, because the functions related to radio frequency control (such as signal modulation, coding, radio frequency shift, etc.) are highly time-related, and it is better to put these functions in a central processing unit (central processing unit). unit, CPU) core, and run a real-time operating system on this CPU core, so that the vulnerability of the operating system and driver on the AP core will not cause the device to send catastrophic data to the mobile network; and once the BP is blocked With good design and certification, no matter how the operating system and application software used are changed, it can correctly perform the communication function, and the designer of the mobile phone can also design the user interface and application software more freely. Specifically, the operating system, user interface and application programs all run on the AP; RF communication and control software run on the BP.

When the AP of the terminal detects that it needs to connect to the USB3.0 for data transmission through the wired data transmission interface, it can send a broadcast to the radio frequency modem in the BP, which can be called a target broadcast here. The target broadcast is used to control the radio frequency modem to acquire the radio frequency call state in the BP, that is, to control the radio frequency modem to acquire the call state information of the terminal. After the radio modem obtains the call state information of the terminal, it can return the obtained call state information to the AP, and the AP can perform call detection on the terminal according to the received call state information. The call detection may specifically include detecting whether the terminal is in a call state and further detecting what type of call state the terminal is in when the terminal is in a call state. The call state type of the terminal may specifically include a GSM call (that is, a 2G call), a 3G call (where 3G is the 3-generation, the third-generation mobile communication technology), and the voice over long-term evolution (Voice over Long-Term Evolution, VoLTE) Calls (ie, 4G calls) and New Radio (NR) calls (ie, 5G calls). The radio frequency modem can determine what type of call state the terminal is currently in by detecting the frequency band of the working voice channel.

In 120, if the terminal uses the preset frequency band to make a call, the target antenna is determined from multiple antennas of the terminal.

Wherein, when the AP determines that the terminal is currently in a call state through the call state information returned by the radio modem, it can further determine what type of call the terminal is currently in. For example, it is determined that the terminal is currently in a GSM call or a 3G call.

In this case, it can be further determined whether the call type currently described by the terminal is a preset call type. Wherein, since different call types use different frequency bands, it can be judged whether the call adopts the preset call type to conduct the call by judging the call frequency band currently used by the terminal. When it is determined that the terminal uses a preset frequency band for calls, the preset frequency band may be the frequency band that interferes with the wired data transmission interface for data transmission, for example, when the frequency band corresponding to the GSM call type, can be determined from multiple antennas of the terminal. The target antenna, where the distance between the target antenna and the wired data transmission interface is greater than the distance between the antenna used in the current call and the wired data transmission interface.

Specifically, a terminal may have multiple antennas. For example, a mobile phone has an upper antenna and a lower antenna. Generally, the upper antenna is installed at the top of the mobile phone, and the lower antenna is generally installed at the bottom of the mobile phone, close to the microphone and the wired data transmission interface or at the power interface. As shown in FIG. 2 , it is a schematic diagram of the hardware structure of the mobile phone provided by the present application. Wherein, the mobile phone 10 includes a wired data transmission interface 13, and the wired data transmission interface 13 can be used to connect USB3.0 for data transmission. In addition, the mobile phone 10 also includes an upper antenna 11 and a lower antenna 12 . When the mobile phone is on a call, the upper antenna 11 can be used for the call or the lower antenna 12 can be used for the call. The antenna used for the mobile phone call is not specifically limited. The antenna used for the mobile phone call can be based on the real-time call quality. switch. However, since the lower antenna 12 of the mobile phone is very close to the wired data transmission interface 13, if the lower antenna is used to make a call, the main wave energy radiated by the lower antenna will interfere with the data transmission of USB3. It will cause the problem of interruption of USB3.0 data transmission. Then, the upper antenna 11 of the mobile phone can be determined as the target antenna at this time. Since the upper antenna 11 of the mobile phone is farther from the wired data transmission interface 13 than the lower antenna 12, the interference of the energy generated by its radiation to the USB 3.0 will be greatly reduced, thereby ensuring that the USB 3.0 can perform data transmission stably . The mobile phone 10 further includes a radio frequency modem 14 , which is connected to the upper antenna 11 and the lower antenna 12 respectively. The radio frequency modem 14 is used to specifically control the working states of the upper antenna 11 and the lower antenna 12 .

The above mobile phone is just an example, and in some embodiments, the terminal may have a larger number of antennas, for example, three or more antennas. Then, when it is determined that the current data transmission is interfered, that is, the data transmission rate is less than the target rate value, it is determined that the current data transmission is interfered, that is, when the terminal is currently in the call state of the preset frequency band, it can be further determined that the terminal The antenna used for the current call. For example, the terminal has three antennas, namely, antenna A, antenna B, and antenna C, and the distances between the three antennas and the wired data transmission interface are from near to far. Then, if it is determined that the antenna used in the current call is antenna A, antenna B or antenna C can be determined as the target antenna; if the antenna used in the current call is antenna B, antenna C can be determined as the target antenna. If the antenna used for the current call is the antenna C, the antenna C is also determined as the target antenna. Or, in some embodiments, when the terminal has multiple antennas, the antenna with the farthest distance from the wired data transmission interface may be determined as the target antenna.

In 130, the antenna used for the current call is switched to the target antenna for the call.

Wherein, after the target antenna is determined, the antenna used for the current call can be switched to the target antenna for the call. Since the distance between the target antenna and the wired data transmission interface is farther than the distance between the antenna used for the current call and the wired data transmission interface, the main wave energy of radiation generated by the call based on the target antenna is responsible for the connection of the wired data transmission interface. The interference of USB3.0 is smaller, which can improve the stability of the wired data transmission interface using USB3.0 for data transmission.

In some embodiments, switching the antenna used for the current call to the target antenna for the call includes:

1. Generate an antenna locking command according to the target antenna;

2. Send an antenna locking command to the RF modem, so that the RF modem locks the antenna of the current call to the target antenna.

Wherein, in the embodiment of the present application, switching the antenna used for the current call to the target antenna for the call may specifically be sending an antenna lock instruction to the radio frequency modem, and the antenna lock instruction is used to control the radio frequency modem to lock the antenna of the current call to the target antenna. . Specifically, the AP may first generate an antenna locking instruction according to the determined target antenna, and then send the antenna locking instruction to the radio frequency modem, so that the radio frequency modem locks the call antenna to the target antenna. For example, when it is determined that the target antenna is the upper antenna of the mobile phone, an instruction to lock the call antenna to the upper antenna can be sent to the RF modem, so that the RF modem locks the call antenna to the upper antenna of the mobile phone.

In some embodiments, the data transmission method provided by this application may further include:

A. Obtain the data transmission rate of data transmission through the wired data transmission interface;

B. When the data transmission rate is lower than the target rate value, reduce the call power according to the preset adjustment step size until the data transmission rate reaches the target rate value.

Wherein, in the embodiment of the present application, after the antenna used for the current call is switched to the target antenna for the call, the data transmission efficiency of data transmission through the wired data transmission interface can be further obtained, that is, the AP can further obtain the USB3. 0 data transfer rate. If the data transmission rate of USB3.0 can reach the target rate after locking the call antenna to the target antenna, it means that locking the target antenna for call has improved the interference problem caused by call energy to data transmission. USB3.0 for data transfer. If the USB3.0 data transmission rate still does not reach the preset target rate after the call antenna is locked to the target antenna, the call power can be gradually reduced in accordance with the preset step size until the data transmission rate through USB3.0 The target velocity value is reached.

In some embodiments, when the data transmission rate is lower than the target rate value, the call power is reduced according to a preset adjustment step until the data transmission rate reaches the target rate value, including:

B1. When the data transmission rate is lower than the target rate value, a power adjustment instruction is generated according to the preset adjustment step size;

B2. Send a power adjustment command to the radio frequency modem of the terminal, so that the radio frequency modem reduces the call power according to the preset step size until the data transmission rate reaches the target rate value.

Wherein, in this embodiment of the present application, the call power may also be adjusted by using a radio frequency modem. Specifically, when the AP detects that the data transmission rate of USB 3.0 still fails to reach the preset target rate value after the call is made by binding the call antenna to the target antenna, it can adjust the step size according to the preset value to generate Power adjustment command, the power adjustment command is used to adjust the call power. Then, the AP sends the generated power adjustment instruction to the radio frequency modem, so that the radio frequency modem uses the preset adjustment step to reduce the call power of the current call. Among them, when the terminal adopts USB3.0 to transmit data through the wired data transmission interface, if the terminal is also in a call state, the factor that affects the stability of USB3.0 data transmission is more likely to be the antenna radiation during the call. At this time, by controlling Keeping the call antenna away from the wired data transmission interface can reduce antenna radiation near the wired data transmission interface, thereby reducing the impact on USB3.0 data transmission. If the transmission rate of USB3.0 still fails to reach the preset target rate value after controlling the call antenna away from the wired data transmission interface, the radiation intensity at the USB3.0 interface can be further reduced by reducing the call power. Reduce the interference to the data transmission of USB3.0. Among them, the reduction of the call power can be gradually reduced according to a certain adjustment step, so as to avoid the reduction of the call quality caused by too much reduction.

In some embodiments, in a terminal with multiple antennas, when the call antenna is locked on the target antenna and the data transmission rate of USB 3.0 still fails to reach the target rate value, it can be further determined whether there is a distance cable in the terminal The distance between the data transmission interface is greater than the distance between the target antenna and the wired data transmission interface. If there is a better antenna, the call antenna can be further locked to the better antenna to make a call to further reduce the radiation intensity at the USB3.0 interface. Thereby, the interference to USB3.0 data transmission is further reduced, and the stability of USB3.0 data transmission is improved.

In some embodiments, the data transmission method provided by this application further includes:

When it is detected that the data transmission ends, a lock release instruction is sent to the radio frequency modem of the terminal, and the lock release instruction is used to release the lock of the talking antenna.

Wherein, in the embodiment of the present application, after the talking antenna is locked on the target antenna, the data transmission process can be monitored in real time. If it is detected that the data transmission ends, in order to ensure the quality of the call, the antenna locking operation of locking the call antenna to the target antenna can be released. Specifically, after locking the call antenna to the target antenna, the AP can monitor the data transmission in real time. After monitoring the end of the data transmission, the AP can further send a lock release instruction to the radio modem, and the radio modem receives the lock release instruction after receiving the lock release instruction. After that, further unlock the call antenna.

In some embodiments, if the call power reduction control is also performed during the call control process, after the data transmission is completed, the call power reduction operation can be further canceled, so that the call power is restored to the initial value, thereby ensuring conversation quality.

Wherein, in the data transmission method provided by this application, when the terminal adopts USB3.0 for data transmission, if it is detected that the terminal is also conducting a call in a preset frequency band at the same time, the call antenna of the terminal can be locked at a distance from the USB3.0 data transmission. on an antenna with a farther interface. The method reduces the influence of the energy radiated by the call on the USB3.0 data transmission, thereby ensuring the stability of the USB3.0 data transmission. At the same time, since USB3.0 will also bring noise during data transmission, it will also interfere with the call quality during the call. Therefore, locking the call antenna on the antenna farther away from the USB3.0 interface can further improve the call. the quality of.

According to the above description, in the data transmission method provided by the present application, when the terminal performs data transmission through the wired data transmission interface, the terminal performs call detection; if the terminal uses the preset frequency band for the call, the target is determined from multiple antennas of the terminal Antenna, the preset frequency band is the frequency band that interferes with the wired data transmission interface for data transmission, and the distance between the target antenna and the wired data transmission interface is greater than the distance between the antenna used for the current call and the wired data transmission interface; switch the antenna used for the current call to the target antenna Make a call. Through this method, when the terminal performs data transmission through the wired data transmission interface, the antenna used for the call can be switched to the antenna farther away from the wired data transmission interface, thereby reducing the interference of the call frequency band signal on the data transmission, thereby improving the data transmission efficiency. stability.

Please refer to FIG. 3 , which is another schematic flowchart of a data transmission method provided by an embodiment of the present application. As shown in FIG. 3 , the process of the data transmission method provided by the embodiment of the present application may be as follows:

In 210, when the AP of the mobile terminal receives the instruction of using USB3.0 for data transmission, it sends a broadcast to the radio frequency modem of the mobile terminal.

When the data transmission interface of the mobile terminal is connected to USB3.0, and then the user initiates data transmission, the AP of the mobile terminal will send a broadcast to the RF modem in the BP of the mobile terminal after receiving the data transmission instruction. It is used to control the radio frequency modem to perform call detection on the mobile terminal.

In 220, the radio frequency modem of the mobile terminal detects whether the mobile terminal is currently in a call state.

After receiving the broadcast sent by the AP, the radio frequency modem of the mobile terminal detects the call state of the mobile terminal to determine whether the mobile terminal is in the call state. If the mobile terminal is not in a call state, step 280 may be performed, that is, data transmission of USB 3.0 may be performed.

In 230, the radio frequency modem of the mobile terminal detects whether the mobile terminal is in a GSM call state.

When the radio frequency modem of the mobile terminal detects that the mobile terminal is in a call state, it can further detect whether the mobile terminal is in a GSM call state. In general, when the mobile terminal is in a 3G, 4G or 5G call, the radiation energy generated by it is small, and the interference to USB3.0 data transmission is small. If it is detected that the mobile terminal uses 3G, 4G or 5G to make calls, step 280 may be performed, that is, data transmission of USB 3.0 may be performed. If it is detected that the mobile terminal is in a GSM call state, step 240 may be executed.

In 240, the radio frequency modem of the mobile terminal locks the GSM call to the upper antenna.

When it is determined that the mobile terminal adopts the GSM call, the antenna of the GSM call can be locked to the upper antenna of the mobile terminal. Wherein, in general, the lower antenna of the mobile terminal is arranged at the data transmission interface, and the upper antenna is arranged at the top of the mobile terminal and is far away from the data transmission interface. Therefore, when the upper antenna of the mobile terminal is used to make a call, the radiation generated by the antenna has less influence on the USB3.0 interface. At the same time, the interference of the noise generated by USB3.0 to the call will also be reduced, which not only ensures the stability of data transmission but also improves the call quality of the call.

In 250, the AP of the mobile terminal detects whether the transmission rate of the USB 3.0 is lower than the preset rate value.

After locking the call antenna to the upper antenna of the mobile terminal, the AP of the mobile terminal can further detect whether the data transmission rate of the USB 3.0 is lower than a preset rate value. The preset rate value can be set to 480Mbps. If locking the call antenna to the upper antenna still cannot guarantee the data transmission rate of the USB3.0 interface, further call control is required.

In 260, the AP of the mobile terminal sends a power reduction instruction to the radio modem.

Specifically, if the data transmission rate of USB 3.0 cannot be guaranteed even after locking the call antenna of the mobile terminal to the upper antenna, the call power can be further reduced. Specifically, for example, the call power of a GSM call can be reduced by 3dB. At this time, the AP of the mobile terminal may send a power reduction instruction to the radio frequency modem, so that the radio frequency modem performs power reduction processing on the current GSM call.

In 270, the radio frequency modem of the mobile terminal reduces the call power.

After the radio frequency modem of the mobile terminal receives the power reduction instruction sent by the AP of the mobile terminal, it can reduce the power of the current GSM call by 3 dB according to the instruction. Alternatively, in some embodiments, a small power reduction step size can be set, and the RF modem gradually reduces the power of the GSM call according to the step size and monitors the change of the data transmission rate of the USB3.0 interface in real time during the power reduction process. When the data transmission rate of the .0 interface reaches the preset transmission rate value, the power reduction operation can be stopped and data transmission can be continued.

In 280, the AP of the mobile terminal performs USB 3.0 data transmission.

After the power reduction processing is performed on the GSM call, the USB3.0 data transmission task can be continued. When the mobile terminal is not in the call state or the mobile terminal is in the call state but not in the GSM call state, the data transmission task of USB3.0 can also be continued.

In 290, when it is detected that the USB 3.0 data transmission is stopped, the radio frequency modem executes an instruction to release the locked antenna and reduce power.

Among them, in the process of executing the USB3.0 data transmission task, the data transmission status can also be detected in real time. When the end of the data transmission is monitored, the AP of the mobile terminal sends a release instruction to the radio frequency modem of the mobile terminal. The release instruction The command for releasing the antenna and reducing the power, that is, the command for contacting the aforementioned locked antenna to make a call and reducing the power of the call.
