Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
Referring to fig. 1, fig. 1 is a schematic flowchart of an embodiment of a communication control method according to the present application. Specifically, the communication control method of the present application includes the steps of:
step S11: it is detected that the high-speed communication mode is entered by communication between the input-output interface and the external device.
The terminal for implementing the communication control method is, for example, an interphone.
The input/output interface of the terminal is an interface for the terminal to communicate (data transmission) with an external device, for example, a USB interface, which may specifically be a Micro USB interface, a USB Type-C, or the like. The external device is, for example, an electronic device having a data transmission function, such as a computer, a mobile phone, and a tablet computer. The high-speed communication mode is, for example, a communication mode in which communication is performed using the USB2.0 communication protocol and the above versions, or a communication mode in which differential signals are used and the theoretical maximum transmission rate exceeds 12Mbps (1.5 MB/s).
The external device can be connected through the input/output interface of the terminal to perform data transmission. During data transmission, the terminal may detect whether communication between the input-output interface and the external device enters a high-speed communication mode. For example, whether to enter the high-speed communication mode is detected by determining the data transmission rate, or whether to support the USB2.0 communication protocol and its versions or other high-speed communication protocols.
That is, the terminal may detect that the communication with the external device using the input-output interface enters the high-speed communication mode.
Step S12: the transmission power of the radio frequency signal is reduced.
When the terminal transmits data by using differential signals, the differential amplitude is only 400mV, and when the terminal transmits radio frequency signals, taking an interphone as an example, the power can be 4W or 5W when the terminal transmits high power, when the terminal which uses the differential signals to transmit data carries out conversation, the error rate of differential data transmission of the terminal can rise due to the influence of the radio frequency signals, and even the data transmission of the differential signals can be interrupted. Therefore, when the terminal detects that the communication between the input/output interface and the external device enters the high-speed communication mode, the terminal can reduce the transmission power of the radio frequency signal, so as to reduce the influence on the data transmission between the input/output interface of the terminal and the external device.
Reducing the transmit power of the rf signal may reduce the transmit power of the terminal to a predetermined value, such as 1 watt (W). The preset value is not limited and can be adjusted according to actual needs.
Therefore, when the terminal enters a high-speed communication mode by utilizing the communication between the input/output interface and the external device, the interference on the data transmission between the input/output interface and the external device of the terminal is reduced by reducing the transmitting power of the radio frequency signal, and the stability of the data transmission is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart of another embodiment of the communication control method of the present application. Specifically, the communication control method of the present application includes the steps of:
step S21: whether communication with an external device using an input-output interface enters a high-speed communication mode is detected.
When the external device is connected to the terminal through the input/output interface of the terminal to perform data transmission, the terminal may detect whether or not the communication with the external device using the input/output interface enters a high-speed communication mode. For example, whether to enter the high-speed communication mode is detected by determining a rate of data transmission, or whether to enter the high-speed communication mode is detected by determining a USB communication protocol supported by the external device.
In one embodiment, the high-speed communication mode is entered when the terminal detects that the external device currently needs to communicate using the high-speed communication mode. The external device needs to communicate in a high-speed communication mode at present, which can be understood as that the external device needs to transmit data in the high-speed communication mode at present, such as transmitting video data in real time, or transmitting other data in real time. In one embodiment, whether the external device currently requires communication in the high-speed communication mode may be detected by determining the type of the external device, for example, by obtaining a device descriptor of the external device, for example, when the external device is a USB device, the type of the USB device may be determined by obtaining the device descriptor of the USB device. For example, when the external device is a video photographing apparatus, it can be considered that the external device currently needs to communicate using a high-speed communication mode.
When the terminal enters a high-speed communication mode, if the current communication mode is not the high-speed communication mode, the terminal switches to a low-speed communication mode, for example, a communication module corresponding to an input/output interface can be restarted, so as to realize the switching of the communication mode; or directly switching to the low-speed communication mode through breakpoint retransmission.
By detecting whether the external device needs to use the high-speed communication mode at the current moment, the transmitting power of the terminal can be correspondingly adjusted, and the influence on data transmission between the terminal and the external device is reduced.
When it is detected that the communication with the external device using the input-output interface enters the high-speed communication mode, step S22 may be performed; step S23 may be performed when it is detected that the external device does not currently need to utilize the high-speed communication mode.
Step S22: the transmission power of the radio frequency signal is reduced.
Please refer to step S12, which is not described herein.
In one embodiment, when the terminal detects that the communication between the input/output interface and the external device enters the high-speed communication mode, it may further determine whether the communication between the terminal and the external device is already established, and if not, the terminal may restart the communication module corresponding to the input/output interface to establish communication with the external device for data transmission.
Step S23: it is determined whether a communication connection has been established with an external device.
In the case where it is detected that the external device does not currently need to use the high-speed communication mode, this means that the communication between the external device and the terminal does not need to enter the high-speed communication mode or to perform the communication at the present time. At this time, it is possible to determine whether the terminal needs to communicate with the external device by determining whether a communication connection has been established between the terminal and the external device.
When the communication connection is not established between the terminal and the external device, step S24 may be performed; when the communication connection has been established between the terminal and the external device, step S25 may be performed.
Step S24: and closing the communication module corresponding to the input/output interface.
The terminal and the external device are not in communication connection, which means that data communication is not needed between the external device and the terminal at the current moment, and the terminal can close the communication module corresponding to the input/output interface at the moment, so that the power consumption of the terminal is reduced, and the cruising ability of the terminal is improved. For example, when the input/output interface is a USB interface, the USB communication module of the terminal may be turned off.
Step S25: whether the data volume of the transmission data between the external device and the detection device is larger than a preset data volume or not is detected.
The communication connection between the terminal and the external device is already established, which means that data communication is required between the external device and the terminal to transmit data. At this time, it may be determined whether the data volume of the transmission data between the terminal and the external device is greater than the preset data volume, so as to adjust the data transmission rate between the terminal and the external device according to the size of the data volume, thereby improving the data transmission efficiency. The data size of the transfer data may be understood as the size of the transfer file, for example, 800MB or the like. The preset data amount may be set according to actual needs, for example, set to 500MB or more.
When the data amount of the transmission data between the terminal and the external device is not greater than the preset data amount, step S26 may be performed; when the data amount of the transmission data is larger than the preset data amount, the steps S27 and beyond may be performed.
Step S26: it is determined that communication with an external device enters a low-speed communication mode, wherein a transmission rate of the low-speed communication mode is smaller than a transmission rate of a high-speed communication mode.
The data volume of the transmission data between the terminal and the external device is not greater than the preset data volume, the data volume of the data needing to be transmitted is not large, and the terminal does not need to enter a high-speed communication mode, and at the moment, the terminal can determine that the communication between the terminal and the external device enters a low-speed communication mode. The transmission rate of the low-speed communication mode is smaller than that of the high-speed communication mode, and it can be understood that the theoretical maximum transmission rate of the low-speed communication mode is smaller than that of the high-speed communication mode. For example, when the high-speed communication mode is the USB2.0 communication protocol and the above versions of the protocol, the low-speed communication mode may be the USB 1.1 or the USB 1.0 communication protocol.
Step S27: a high speed communication mode is entered.
In order to improve the efficiency of data transmission, the terminal may enter a high-speed communication mode to improve the data transmission rate between the terminal and the external device. Therefore, the terminal can automatically adjust the data transmission rate according to the data size of the transmission data, and the data transmission efficiency is improved.
Step S28: the transmission power of the radio frequency signal is reduced.
Please refer to step S12, which is not described herein.
In one embodiment, after the data amount of the transmission data with the external device is detected to be larger than the preset data amount, the high-speed communication mode is entered, and before the transmission power of the radio frequency signal is reduced, whether the communication between the terminal and the external device is interrupted can be judged to determine whether to reduce the transmission power of the radio frequency signal. When the communication between the terminal and the external device is interrupted, it can be understood that the communication is completely disconnected, and data transmission cannot be performed at this time; or the error rate of the communication between the terminal and the external device rises to a predetermined threshold, which seriously affects the data transmission between the terminal and the external device.
When the communication between the terminal and the external device is interrupted, step S28 may be performed to reduce the transmission power of the radio frequency signal to reduce interference to the communication between the terminal and the external device. When the communication between the terminal and the external device is not interrupted, it may be considered that the transmission power of the signal at the time of the terminal does not cause too much interference to the communication between the terminal and the external device, and step S28 may not be performed, that is, the transmission power of the radio frequency signal is not reduced.
By determining the communication state between the terminal and the external device, the transmitting power of the radio frequency signal of the terminal can be adaptively adjusted, and the transmitting power of the radio frequency signal of the terminal is not reduced under the condition of not causing too much interference to the communication between the terminal and the external device.
In one embodiment, after entering the high-speed communication mode and before determining whether the communication with the external device is interrupted, it may also be determined whether a push to talk function (push to talk) of the terminal is triggered. When the push-to-talk function of the terminal is triggered, which means that the terminal needs to transmit a radio frequency signal at this time, interference may be caused to communication between the terminal and an external device. Therefore, when the push-to-talk function is triggered, the above-mentioned step of determining whether the communication between the terminal and the external device is interrupted may be further performed to determine whether to reduce the transmission power of the radio frequency signal. In addition, when the push-to-talk function of the terminal is not triggered, it means that the terminal does not need to transmit the radio frequency signal at this time, and the transmission power of the radio frequency signal may not be adjusted.
Whether the transmitting power of the radio frequency signal of the terminal is adjusted or not can be determined by judging whether the push-to-talk function of the terminal is triggered or not.
In the above embodiment, when the terminal switches between the high-speed communication mode and the low-speed communication mode, if the terminal is currently in the high-speed communication mode and needs to switch to the low-speed communication mode, or needs to switch from the low-speed communication mode to the high-speed communication mode, the terminal may restart the communication module corresponding to the input/output interface, so as to implement switching of the communication modes.
According to the scheme, the interference on data transmission between the input and output interfaces of the terminal and an external device can be reduced by adjusting the transmitting power of the radio frequency signal of the terminal, and the stability of data transmission is improved.
Referring to fig. 3, fig. 3 is a schematic diagram of a framework of an embodiment of the mobile communication terminal of the present application. In the present embodiment, the mobile communication terminal 30 includes a detection circuit 31 and a power adjustment circuit 32. The detection circuit 31 is used for detecting whether the communication between the input/output interface and the external device enters a high-speed communication mode, and the power adjustment circuit 32 is used for reducing the transmission power of the radio frequency signal when the detection circuit detects that the communication between the input/output interface and the external device enters the high-speed communication mode.
Optionally, the detecting circuit 31 detects that the communication with the external device using the input/output interface enters the high-speed communication mode, and includes: when detecting that the external device needs to communicate in a high-speed communication mode at present, entering the high-speed communication mode; or, if the data volume of the transmission data with the external device is detected to be larger than the preset data volume, entering a high-speed communication mode.

Optionally, the mobile communication terminal 30 further includes a communication connection detection circuit.

In the case where the communication connection with the external device is established, the detection circuit 31 may detect whether the data amount of the transmission data with the external device is larger than a preset data amount.
Alternatively, in a case where the communication connection detection circuit detects that the communication connection with the external device is not established, the mobile communication terminal 30 may turn off the communication module corresponding to the input/output interface. When the detection circuit 31 detects that the data amount of the transmission data with the external device is not more than the preset data amount, the mobile communication terminal 30 determines that the communication with the external device enters a low-speed communication mode in which the transmission rate is smaller than that of the high-speed communication mode.
Optionally, after the detection circuit 31 detects that the data amount of the transmission data with the external device is greater than the preset data amount, and after the mobile communication terminal 30 enters the high-speed communication mode, and before the power adjustment circuit 32 reduces the transmission power of the radio frequency signal, the communication connection detection circuit may further determine whether the communication with the external device is interrupted, and under the condition of interruption, the power adjustment circuit 32 reduces the transmission power of the radio frequency signal; without interruption, the power adjustment circuit 32 does not adjust the transmission power of the rf signal.
Optionally, the mobile communication terminal 30 further includes a push-to-talk function detection circuit. After the mobile communication terminal 30 enters the high-speed communication mode and before the communication connection detection circuit can also judge whether the communication with the external device is interrupted, the push-to-talk function detection circuit can judge whether the push-to-talk function is triggered, and in the case of triggering, the communication connection detection circuit judges whether the communication with the external device is interrupted; in the absence of a trigger, the power adjustment circuit 32 does not adjust the transmit power of the radio frequency signal.
