Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a communication control method of the present application. Specifically, the communication control method of the present application includes the steps of:
step S11: it is detected that a high-speed communication mode is entered by communication between the input-output interface and the external device.
The terminal implementing the communication control method of the present application is, for example, an intercom.
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, specifically, a Micro USB interface, a USB Type-C, and the like. The external device is, for example, an electronic device with a data transmission function, such as a computer, a mobile phone, a tablet computer, and the like. The high-speed communication mode is, for example, a communication mode in which communication is performed in the USB2.0 communication protocol and above, or a communication mode in which differential signals are utilized and the theoretical maximum transmission rate exceeds 12Mbps (1.5 MB/s).
The external device may be connected through an input-output interface of the terminal for 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 rate of data transmission, or whether the external device supports the USB2.0 communication protocol and the above version of the protocol or other high-speed communication protocols.
That is, the terminal can detect that the high-speed communication mode is entered by using the communication between the input-output interface and the external device.
Step S12: reducing the transmitting power of the radio frequency signal.
When the terminal uses the differential signal to transmit data, the differential amplitude is only 400mV, and when the terminal transmits the radio frequency signal, the power can be 4W or 5W when the terminal transmits the high power by taking an interphone as an example, and when the terminal which uses the differential signal to transmit data is communicating, the error rate of the differential data transmission of the terminal can be increased due to the influence of the radio frequency signal, even the data transmission of the differential signal can be interrupted. Therefore, when the terminal detects that the communication between the input/output interface and the external device is utilized to enter the high-speed communication mode, the terminal can reduce the transmitting power of the radio frequency signal, thereby reducing the influence on the data transmission between the input/output interface of the terminal and the external device.
Reducing the transmit power of the radio frequency signal may reduce the transmit power of the terminal to a preset value, for example, 1 watt (W). The setting of 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 and output interface and the external device, the interference on data transmission between the input and output interface of the terminal and the external device 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 flow chart 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: it is detected whether communication between the input-output interface and the external device is entered into a high-speed communication mode.
When the external device is connected with the terminal through the input-output interface of the terminal for data transmission, the terminal can detect whether the communication between the input-output interface and the external device is utilized to enter a high-speed communication mode. For example, whether to enter the high-speed communication mode is detected by judging the rate of data transmission, or whether to enter the high-speed communication mode is detected by judging the 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 is currently required to communicate using the high-speed communication mode. The external device currently needs to communicate in the high-speed communication mode, which can be understood that the external device needs to transmit data in the high-speed communication mode at the current moment, for example, real-time video data transmission, or real-time other data transmission, etc. In one embodiment, whether the external device is currently required to communicate using the high-speed communication mode may be detected by determining the type of the external device, for example, by acquiring 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 acquiring a 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 is switched to a low-speed communication mode, for example, a communication module corresponding to an input/output interface can be restarted, so that the switching of the communication modes is realized; or directly switch to a low-speed communication mode through breakpoint retransmission.
By detecting whether the external device needs to utilize 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 between the input-output interface and the external device is entered into 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: reducing the transmitting power of the radio frequency signal.
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 is used to enter 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 with an external device has been established.
In the case where it is detected that the external device does not need to utilize the high-speed communication mode at present, it means that communication between the external device and the terminal does not need to enter the high-speed communication mode or do not need to be performed at the present moment. At this time, it may be determined whether a communication connection has been established between the terminal and the external device to determine whether the terminal needs to communicate with the external device.
When no communication connection is established between the terminal and the external device, step S24 may be performed; when a 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 fact that communication connection is not established between the terminal and the external device means that data communication is not needed between the external device and the terminal at the current moment, and at the moment, the terminal can close a communication module corresponding to the input/output interface, so that power consumption of the terminal is reduced, and 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: detecting whether the data amount of the transmission data with the external device is larger than a preset data amount.
The communication connection between the terminal and the external device is already established, meaning 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 amount of the transmission data between the terminal and the external device is greater than the preset data amount, so as to adjust the data transmission rate between the terminal and the external device according to the data amount, thereby improving the data transmission efficiency. The data amount of the transmission data can be understood as the size of the transmission file, for example, 800MB or the like. The preset data amount may be set according to actual needs, for example, 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 greater than the preset data amount, step S27 and the following steps 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 the high-speed communication mode.
The amount of data of the transmission data between the terminal and the external device is not more than the preset amount of data, and it can be considered that the amount of data of the data to be transmitted is not large, and it is unnecessary to enter the high-speed communication mode, at which time the terminal can determine that the communication with the external device enters the 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 above, then the low-speed communication mode may be the USB 1.1 or USB 1.0 communication protocol.
Step S27: a high-speed communication mode is entered.
The data amount of the transmission data between the terminal and the external device is larger than the preset data amount, and in order to improve the data transmission efficiency, the terminal can enter a high-speed communication mode at this time so as 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 volume of the transmission data, and the data transmission efficiency is improved.
Step S28: reducing the transmitting power of the radio frequency signal.
Please refer to step S12, which is not described herein.
In one embodiment, after detecting that the data amount of the transmission data with the external device is greater than the preset data amount, entering the high-speed communication mode, and before reducing the transmission power of the radio frequency signal, it may also be determined whether the communication between the terminal and the external device is interrupted, to determine whether to reduce the transmission power of the radio frequency signal. The communication between the terminal and the external device is interrupted, and the communication can be understood to be completely disconnected, so that data transmission cannot be performed at the moment; or the error rate of the communication between the terminal and the external device rises to a predetermined threshold value, seriously affecting the data transmission between the terminal and the external device.
When the communication between the terminal and the external device is interrupted, step S28 of reducing the transmission power of the radio frequency signal to reduce the interference to the communication between the terminal and the external device may be performed. 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, i.e., the transmission power of the radio frequency signal is not reduced.
By determining the communication state between the terminal and the external device, the transmission power of the radio frequency signal of the terminal can be adaptively adjusted, and the transmission power of the radio frequency signal of the terminal is not reduced under the condition that too much interference is not caused to the communication between the terminal and the external device.
In one embodiment, after entering the high-speed communication mode and before determining whether 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, meaning that the terminal needs to transmit radio frequency signals at this time, interference may be caused to communication between the terminal and an external device. Therefore, the above-described step of judging whether or not the communication between the terminal and the external device is interrupted may be further performed when the push-to-talk function is triggered, thereby determining whether or not 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.
By determining whether the push-to-talk function of the terminal is triggered, it is possible to determine whether to adjust the transmit power of the radio frequency signal of the terminal.
In the above embodiment, when the terminal performs the switching 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 the switching of the communication modes.
According to the scheme, the interference on data transmission between the terminal input/output interface and the external device can be reduced by adjusting the transmitting power of the radio frequency signal of the terminal, and the stability of the data transmission is improved.

Alternatively, in the case where the communication connection detection circuit detects that no communication connection is established with the external device, 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 greater 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, the mobile communication terminal 30 further comprises 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 determine whether or not the communication with the external device is interrupted, the push-to-talk function detection circuit can determine whether or not the push-to-talk function is triggered, and in the case of triggering, the communication connection detection circuit determines whether or not 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.
