Technical Field

Background

With the evolution and innovation of the technology, the terminal devices have wider and wider applications, and the scenes of using the VOIP call are more and more common, and when the terminal performs the VOIP (voice over Internet protocol) call, the larger the transmission power is, the better the communication quality is, but correspondingly, the user is subjected to larger radiation, so that the transmission power of the terminal needs to be adjusted.

The existing method for adjusting the transmitting power of the terminal is usually based on the voice call of the CS domain and the data service scene of the PS domain, is not suitable for the VOIP call scene, and no reliable technical scheme for controlling the transmitting power of the terminal aiming at the VOIP call scene exists at present.

Disclosure of Invention

The embodiment of the application provides a transmission power adjusting method, a terminal, a storage medium and electronic equipment, which can control the transmission power of the terminal aiming at a VOIP call scene and reduce radiation during VOIP call.

In a first aspect, an embodiment of the present application provides a method for adjusting transmit power, which is applied to a terminal, and includes: when the terminal carries out VOIP conversation, if the receiver of the terminal is detected to be in an open state and the current transmitting power of the terminal is larger than a preset power threshold value, the transmitting power is reduced, so that the reduced transmitting power is smaller than or equal to the preset power threshold value.

The preset power threshold may be determined according to an SAR index, specifically, according to an SAR index of each country or region, a transmission power value that meets the SAR index is determined as the preset power threshold, and the preset power threshold may be an upper limit value of the transmission power, which is predetermined, and the like.

It can be understood that, by designing the scheme for controlling the transmission power in the VOIP call, the embodiment of the invention enables a user to adjust the transmission power of the terminal when the user uses the terminal to perform the VOIP call and the terminal is close to the head of the user, so as to reduce the electromagnetic radiation of the terminal in the scene and reduce the influence on the body and the user of the user.

With reference to the first aspect, in a possible implementation manner, before the reducing the transmission power, the method further includes:

detecting whether the terminal carries out VOIP call;

if so, detecting whether a receiver of the terminal is in an open state and detecting whether the current transmitting power of the terminal is greater than the preset power threshold value;

the detecting whether the terminal carries out the VOIP call comprises the following steps:

and when the audio mode of the audio module of the terminal is the VOIP call mode, determining that the terminal is carrying out the VOIP call, otherwise, determining that the terminal is not carrying out the VOIP call.

In one or more embodiments of the invention, the terminal may determine whether the terminal is conducting a VOIP call by detecting an audio mode of the audio module. In one example, the audio modes of the audio module include, but are not limited to: normal mode, ring mode, normal talk mode, and VOIP talk mode. The normal mode may be, for example, a mode in which the audio module is located when the terminal is in a state of music playing, standby, or the like, the ringing mode may be, for example, a mode in which the audio module is located when the terminal has incoming call reminding, WeChat voice reminding, or the like, the normal call mode is a mode in which the audio module is located when the terminal performs a normal call based on an operator, and the VOIP call mode is a mode in which the audio module is located when the terminal performs a VOIP call.

Illustratively, when the terminal is a called party and the terminal connects to the called phone, the audio mode of the audio module may have a change process from a normal mode to a ring mode and then to a normal call mode. When the terminal is a calling party and a calling phone is connected, the audio mode of the audio module can have a changing process of switching from a normal mode to a common call mode.

Illustratively, when the terminal is a called party and the terminal connects a called VOIP call, the audio mode of the audio module may have a changing process of switching from a normal mode to a ring mode and then switching to a VOIP call mode. When the terminal is a calling party and a calling VOIP call is connected, the audio mode of the audio module can have a change process of switching from a normal mode to a VOIP call mode. The audio module in the terminal can detect the VOIP call state of the terminal, when the terminal starts to carry out the VOIP call, the audio module senses whether the VOIP call is in progress or not and sets the audio mode to be the VOIP call mode, the processor monitors the audio mode of the audio module, and when the audio mode of the audio module is the VOIP call mode, the current terminal is determined to carry out the VOIP call.

When the terminal uses the loudspeaker to carry out VOIP conversation, the audio module sends the audio electric signal to the loudspeaker, the loudspeaker converts the audio electric signal into a sound signal, and the audio module informs the processor of the change of the state of the loudspeaker, so that the processor can know the working state of the loudspeaker.

When the terminal is inserted into the wired earphone, the level of the detection pin in the earphone interface changes to cause interruption, so that the detection pin of the earphone interface detects the insertion and extraction states of the wired earphone, and when the wired earphone is connected or extracted, the processor is informed, so that the processor can know the state of the wired earphone. When the terminal carries out VOIP conversation through the wired earphone, the audio module sends the audio electrical signal to the wired earphone, and the wired earphone converts the audio electrical signal into a sound signal.

if the terminal is still in a VOIP call state and the receiver of the terminal is still in an open state and the current transmitting power of the terminal is still larger than the preset power threshold when the first preset time length is reached after the first prompt message is generated, the transmitting power is reduced, and the reduced transmitting power is smaller than or equal to the preset power threshold.

if not, continuing to increase the transmitting power, and repeating the steps until the VOIP call quality is detected to be qualified;

if so, the increase of the transmission power is stopped.

Preferably, in order to better fit practical applications, in the embodiment of the present invention, the value of the transmit power that the terminal increases each time is the same, for example, each increase is 0.2 dBm.

It can be understood that the terminal does not stop increasing the transmission power until the VOIP call quality is detected to be qualified, so that the quality of the VOIP call can be ensured to be qualified while the transmission power is reduced as much as possible.

The transmission power adjustment method provided by the embodiment of the application can be applied to various network call scenes realized based on the VOIP protocol, for example: the method for adjusting the transmitting power can be used for carrying out VOIP voice call or VOIP video call by two users through the terminals used by the users respectively, or carrying out VOIP voice conference or VOIP video conference by a plurality of users through the terminals used by the users respectively.

Fig. 3 is a schematic diagram of two users conducting VOIP voice calls through respective terminals;

the scenario shown in fig. 3 is: the user A and the user B carry out VOIP conversation through the respective used terminals; in general, when a voice signal is transmitted through the receiver, the voice transmitted by the receiver is small and needs to be close to the ear to be heard normally, so that the terminal used by the user a for performing the VOIP call is close to the head of the user a, the user B for performing the voice signal transmission through the earphone is not close to the head of the user B.

The core thought of the transmitting power adjusting method provided by the embodiment of the invention is as follows: when the terminal detects that the terminal is currently carrying out the VOIP call, the state of a receiver of the terminal and/or the current transmitting power value of the terminal are/is acquired, and if the state of the receiver of the terminal is an open (starting) state and the current transmitting power value of the terminal does not meet the preset requirement, the terminal is determined to be close to the head of a user when carrying out the VOIP call, so that the current transmitting power of the terminal needs to be adjusted to enable the current transmitting power of the terminal to meet the preset requirement.

By the transmission power adjusting method provided by the embodiment of the invention, the terminal used by the user A for carrying out the VOIP call is close to the head of the user A, and under the normal condition, the head of the user is more sensitive to radiation relative to the body part of the user, so that under the transmission power range which can be reached by the terminal at present, if the distance between the terminal and the head of the user is too close, the body of the user is still affected, and therefore, when the terminal judges that the terminal is close to the head of the user A and the transmission power exceeds a preset value, the transmission power is reduced. The terminal used by the user B is not close to the brain of the user, so that no processing or other processing can be performed, which is not limited by the present invention.

Fig. 4 is a flow chart of a method for adjusting transmission power according to an embodiment of the present invention;

as shown in fig. 4, the method for adjusting the transmission power may include:

step S11: when the terminal carries out VOIP conversation, if the receiver of the terminal is detected to be in an open state and the current transmitting power of the terminal is larger than the preset power threshold value, the transmitting power is reduced, so that the reduced transmitting power is smaller than or equal to the preset power threshold value.

Referring to fig. 5, in one embodiment of the present invention, the terminal 100 includes: processor 110, audio module 170, speaker 170A, headphones 170B, microphone 170C, headset interface 170D, and bluetooth module 160A.

In the embodiment of the present invention, the bluetooth module 160A may be disposed in the wireless communication module 160, or may be disposed in the processor 110, or a part of the functional modules of the bluetooth module 160A is disposed in the processor 110, and a part of the functional modules is disposed in the wireless communication module 160.

In the embodiment of the present invention, the detection of whether the terminal performs the VOIP call is implemented by the audio module 170 inside the terminal 100, and the detection of the terminal performing the VOIP call is specifically to detect whether the terminal is in the VOIP call mode.

In one or more embodiments of the present invention, the terminal 100 may detect whether the terminal performs the VOIP call through the audio mode of the audio module 170. In one example, the audio modes of the audio module 170 include, but are not limited to: normal mode, ringing mode, normal talk mode and VOIP talk mode. The normal mode may be, for example, a mode in which the audio module 170 is located when the terminal 100 is in a state of music playing, standby, or the like, the ring mode may be, for example, a mode in which the audio module 170 is located when the terminal 100 has an incoming call alert, a WeChat voice alert, or the like, the normal call mode is a mode in which the audio module 170 is located when the terminal 100 performs a normal call based on an operator, and the VOIP call mode is a mode in which the audio module 170 is located when the terminal 100 performs a VOIP call.

Illustratively, when the terminal 100 is a called party and the terminal 100 connects a called phone, the audio mode of the audio module 170 may have a change process of switching from a normal mode to a ring mode and then to a normal call mode. When the terminal 100 is a calling party and a calling phone is connected, the audio mode of the audio module 170 may have a change process of switching from the normal mode to the normal call mode.

Illustratively, when the terminal 100 is a called party and the terminal 100 connects a called VOIP call, the audio mode of the audio module 170 may have a changing process of switching from a normal mode to a ring mode and then switching to a VOIP call mode. When the terminal 100 is a calling party and a calling VOIP call is connected, the audio mode of the audio module 170 may have a changing process of switching from the normal mode to the VOIP call mode. The audio module 170 in the terminal 100 may detect whether the terminal 100 performs the VOIP call, when the terminal 100 starts performing the VOIP call, the audio module 170 may sense and set the audio mode to the VOIP call mode, and the processor 110 may determine that the terminal 100 is performing the VOIP call by monitoring the audio mode of the audio module 170, when the audio mode of the audio module 170 is the VOIP call mode.

In the embodiment of the present invention, the detection of the state of the receiver 170B by the terminal 100 is determined by the state of other audio components except the receiver 170B. Specifically, when the terminal 100 performs the VOIP call and all other audio components of the terminal 100 except the receiver 170B are in an unopened or unused state, it is determined that the receiver 170B is in an opened state; when the terminal 100 performs a VOIP call, and at least one of the other audio components of the terminal except the receiver 170B is in an on or in use state, it is determined that the receiver 170B is in an off state. In some embodiments of the present invention, the audio component of the terminal includes, but is not limited to, one or more of a speaker 170A, a receiver 170B, a wired headset and a bluetooth headset, for example, the audio component may include the speaker 170A, the receiver 170B, the wired headset and the bluetooth headset, or only include the speaker 170A and the receiver 170B; the speaker 170A and the receiver 170B are disposed inside the terminal 100 and connected to the audio module 170A, the wired headset realizes sound signal transmission with the terminal 100 through the headset interface 170D, and the bluetooth headset realizes sound signal transmission with the terminal 100 through the bluetooth module 160A.

It should be noted that, in the prior art, the terminal 100 cannot directly acquire the state of the receiver 170B based on the security considerations of the terminal 100 system, and therefore, the embodiment provides a solution for detecting the state of the receiver 170B, which has high reliability and does not have unsafe effect on the terminal system.

In conjunction with fig. 1, to further determine whether the user is approaching the terminal 100 to the face or ear, in some embodiments of the present invention, when the terminal performs a VOIP call, if it is detected that the receiver 170B of the terminal 100 is in an open state and the current transmission power of the terminal 100 is greater than a preset power threshold, the terminal 100 may detect whether the distance between the terminal 100 and the head of the user is less than a preset value through the sensor module 180, for example, by one or more of the proximity light sensor 180G, the acceleration sensor 180E and the gyro sensor 180B in the sensor module 180, whether the distance between the terminal 100 and the head of the user is smaller than a preset value is detected to determine whether the user has an operation of bringing the terminal 100 close to the face or close to the ear or whether the user has a call with the terminal 100 close to the ear. For example, a photodiode in the gyro sensor 180B may detect infrared reflected light from a nearby object, and when sufficient reflected light is detected, it may be determined that there is an object near the terminal 100. When insufficient reflected light is detected, the terminal 100 may determine that there is no object near the terminal 100 and the distance between the terminal 100 and the nearby object, and thus, the terminal 100 may detect whether the distance between the user holding the terminal 100 and the user's head is less than a preset value using the proximity light sensor 180G; for another example, the acceleration sensor 180E in the terminal 100 may detect the magnitude of acceleration of the terminal 100 in various directions (generally, three axes), and the gyro sensor 180B in the terminal 100 determines the angular velocity of the terminal 100 around three axes (i.e., x, y, and z axes), and thus, the motion attitude of the terminal 100 may be recognized by the acceleration sensor 180E or the gyro sensor 180B, so that the terminal 100 may detect whether the distance between the terminal 100 and the head of the user is less than a preset value by means of output signals of the acceleration sensor 180E and the gyro sensor 180B.

Based on the above, in one implementation manner, when the terminal 100 performs the VOIP call, if all other audio components in the terminal 100 except the receiver 170B are in an unopened or unused state and the current transmission power of the terminal is greater than the preset power threshold, it is detected whether the distance between the terminal and the head of the user is smaller than the preset value through the proximity light sensor 180G and/or the acceleration sensor 180E and/or the gyroscope sensor 180B in the terminal 100, and if so, the transmission power is reduced so that the reduced transmission power is smaller than or equal to the preset power threshold. If not, the operation of reducing the transmission power is not carried out.

As shown in table one, for example, the audio component of the terminal 100 includes the speaker 170A, the receiver 170B, the wired earphone and the bluetooth earphone, if the terminal 100 performs the VOIP call, the speaker 170A of the terminal 100 is in the off state, the wired earphone is in the pull-out state, and the bluetooth earphone is in the unconnected state, it indicates that the terminal 100 is currently performing the VOIP call using the receiver 170B, and if the speaker 170A of the terminal 100 is in the on state, the earphone is in the plug-in state, or the bluetooth earphone is in the connected state, it indicates that the terminal 100 does not perform the VOIP call using the receiver 170B.

Table one:

state of the receiver	State of wired earphone	BluetoothEarphone state	Loudspeaker state
				Open	Close off	Close off	Close off
Close off	Open	Close off	Close off
				Close off	Close off	Open	Close off
Close off	Close off	Close off	Open

When the terminal 100 performs a VOIP call using the speaker, the audio module 170 converts the audio electric signal into a sound signal by transmitting the audio electric signal to the speaker 170A, and at the same time, the audio module 170 notifies the processor 110 of a change in the state of the speaker 170A, so that the processor 110 can know the operating state of the speaker 170A.

When the terminal 100 is plugged into a wired headset, the level of the detection pin in the headset interface 170D may change, causing an interruption, and therefore, the detection pin of the headset interface 170D detects the plugging and unplugging state of the wired headset, and when the wired headset is plugged in or unplugged, the processor 110 is notified, so that the processor 110 can know the state of the wired headset. When the terminal 100 performs the VOIP call through the wired headset, the audio module 170 converts the audio electrical signal into a sound signal by transmitting the audio electrical signal to the wired headset.

The bluetooth headset communicates with the bluetooth module 160A, and when the bluetooth headset is connected to or disconnected from the bluetooth module 160A, the bluetooth module 160A notifies the processor 110 of the state of the bluetooth headset, so that the processor 110 can know whether the wired headset is connected to the terminal 100. When the terminal 100 performs the VOIP call through the bluetooth headset, the audio module 170 transmits the audio signal to the bluetooth module 160A to implement a function of transmitting sound through the bluetooth headset.

It should be noted that the state of the receiver 170B/speaker 170A in the embodiment of the present invention specifically refers to whether the receiver 170B/speaker 170A is turned on or working, that is, the receiver 170B/speaker 170A has a working state and a non-working state, and does not refer to the state of the receiver 170B/speaker 170A when working or other states; similarly, the state of the wired headset in the embodiment of the present invention specifically refers to whether the terminal 100 is plugged into the wired headset, and the state of the bluetooth headset refers to whether the terminal 100 is wirelessly connected to the bluetooth headset, which is emphasized here to avoid causing ambiguity.

The preset power threshold may be determined according to an SAR index, specifically, according to an SAR index of each country or region, a transmission power value that meets the SAR index is determined as the preset power threshold, and the preset power threshold may be an upper limit value of the transmission power.

The current transmission power of the terminal 100 is the current Total Radiated Power (TRP) of the antenna of the terminal 100. Taking the terminal 100 shown in fig. 1 as an example, the terminal 100 includes an antenna 1 and an antenna 2, and then the current transmission power of the terminal 100 is the sum of the transmission powers of the antenna 1 and the antenna 2, i.e. the total radiation power.

In the scenario of this embodiment, usually, when the current transmit power is higher than a preset power threshold, the transmit power is reduced, and when the transmit power is adjusted, a preset value may be reduced, for example, 2dBm is reduced on the basis of the current transmit power; or the current transmission power is reduced to a preset value, for example, the preset power threshold is 25dBm, and when the current transmission power of the terminal 100 is 27dBm, the terminal 100 adjusts the current transmission power to 25 dBm; or dynamically adjust the current transmit power according to the current transmit power, for example, reduce the current transmit power by 5%. Of course, other adjustment manners are also possible, and the embodiment of the present invention is not limited thereto.

Further, as shown in fig. 4, the method for adjusting the transmission power may further include:

step S12: and when the terminal detects that the VOIP call is hung up or the telephone receiver is closed, restoring the adjustment of the transmitting power.

For example, if the terminal 100 performs the process of reducing the transmission power by 2dBm in step S11, when the terminal 100 detects that the VOIP call is hung up or the receiver 170B is turned off, the reduced 2dBm is recovered. The detection of the VOIP call state and the detection of the state of the receiver 170B are described above, and are not described in detail herein.

Fig. 6 is an exemplary working flow chart of a method for adjusting transmission power according to an embodiment of the present invention.

Referring to fig. 6, a flow of a method for adjusting transmission power in an example may be shown in fig. 6, which includes:

step S21: the terminal detects whether to connect the VOIP call, if yes, the step S22a is carried out, and if not, the terminal continues to detect whether to connect the VOIP call;

step S22 a: detecting whether the telephone receiver is opened, if so, entering the step S23a, and if not, continuously detecting whether the telephone receiver is opened;

step S26: controlling the mobile communication module to reduce the transmitting power of the antenna main frequency signal; proceeding to step S28;

step S27: judging whether the VOIP call is hung up or whether a receiver is closed, if so, entering S29, and if not, continuing to adjust the Wi-Fi signal transmitting power;

step S28: judging whether the VOIP call is hung up or whether the receiver is closed, if so, entering S30, and if not, continuing to adjust the antenna main frequency signal;

step S29: controlling the Wi-Fi module to recover the adjustment of the transmitting power of the terminal;

step S30: and controlling the mobile communication module to recover the adjustment of the transmitting power of the terminal.

In a specific implementation, with reference to fig. 1 and fig. 7, the terminal 100 includes a processor 110, a wireless communication module 160, and a mobile communication module 150, where the wireless communication module 160 includes a Wi-Fi module 160B, and a network connection mode of the terminal 100 includes a traffic data connection and a Wi-Fi connection, where the Wi-Fi connection of the terminal 100 is implemented by the Wi-Fi module 160B, and the traffic data connection of the terminal is implemented by the mobile communication module 150.

When the traffic data connection is used, the processor 110 generates a first control command to the mobile communication module 150, and finally changes the rf parameters of the mobile communication module 150, so as to achieve the purpose of changing the antenna transmission power of the terminal 100. When the Wi-Fi connection is established, the processor 110 of the terminal 100 generates a second control command to the Wi-Fi module 160B of the wireless communication module 160, and finally changes the radio frequency parameter of the Wi-Fi module 160B, so as to change the antenna transmission power of the terminal 100. The first control command and the second control command may be two different AT (attention) commands, respectively, where the AT commands are commands for performing communication inside the terminal 100, and the terminal 100 can control a plurality of behaviors of the terminal 100 through the AT commands, including dialing a number, performing key control, performing fax, performing GPRS, performing power control, and the like.

In other embodiments of the present invention, the order of detecting the state of the VOIP call, determining the state of the receiver, determining whether the transmitting power is greater than the preset power threshold, and detecting the data connection mode may be adjusted, for example, when detecting that the VOIP call is connected, it may be determined first whether the current transmitting power at the terminal 100 is greater than the preset power threshold, and if not, it may then detect whether the receiver 170B is opened and the current data connection mode; of course, the detection of the state of the VOIP call, the judgment of the state of the receiver 170B, the judgment of whether the transmission power is greater than the preset power threshold, and the detection of the data connection mode may also be performed simultaneously, which is not limited in the present invention.

Since the specific implementation process of the detection of the VOIP call state and the detection of the state of the receiver 170B are described above, reference may be made to the above corresponding contents, and in order to avoid repetition, the details are not repeated here.

Fig. 8 is a flowchart of a transmit power adjustment method according to an embodiment of the present invention.

The embodiment of the invention provides a method for adjusting transmission power, which is applied to a terminal 100 and comprises the following steps:

step S31: when a terminal carries out VOIP conversation, if a receiver of the terminal is detected to be in an open state and the current transmitting power of the terminal is greater than a preset power threshold value, first prompt information is generated;

step S32: and if the first preset time length is reached after the first prompt message is generated, the terminal is still in the VOIP conversation state, the receiver of the terminal is still in the open state, and the current transmitting power of the terminal is still larger than the preset power threshold value, the transmitting power of the terminal is reduced, so that the reduced transmitting power is smaller than or equal to the preset power threshold value.

Referring to fig. 9, in the present embodiment, the terminal 100 may include, but is not limited to, a processor 110, an audio module 170, a speaker 170A, a receiver 170B, an earphone interface 170D, a display screen 194 and a motor 191.

Wherein: the first prompt message may be in the form of one or more of a vibration prompt, a sound prompt and an interface message prompt, the vibration prompt may be generated by the motor 191, and the processor 110 controls the motor 191 to operate, so as to generate vibration; the voice prompt may be generated by the receiver 170B, the processor 110 generates an audio electric signal by controlling the audio module 170, and the receiver 170B converts the audio electric signal into a sound signal; the interface information prompt may be displayed by the processor 110 controlling the display screen 194.

Generating the first reminder information may include, but is not limited to, the following:

(1) generating only a vibration prompt;

when the terminal 100 performs the VOIP call, if the receiver 170B of the terminal 100 is in the open state and the current transmission power of the terminal 100 is greater than the preset power threshold, the processor 110 of the terminal 100 controls the motor 191 to operate so as to generate vibration, so as to prompt the user, wherein the time and the vibration mode for generating the vibration can be flexibly set.

When the preset time range after the vibration starts or the preset time range after the vibration stops, if the terminal 100 is still carrying out the VOIP call, and the receiver 170B of the terminal 100 is still in the open state, and the current transmission power of the terminal 100 is still greater than the preset power threshold, the transmission power is reduced, so that the transmission power is reduced to be less than or equal to the preset power threshold.

The specific process of reducing the transmission power, which has been described above, may refer to the corresponding content above, and is not repeated here to avoid repetition.

(2) Generating only the voice prompt;

when the terminal 100 performs the VOIP call, if the receiver 170B of the terminal 100 is in an open state and the current transmission power of the terminal 100 is greater than the preset power threshold, the processor 110 of the terminal 100 controls the receiver 170B to generate an audio prompt, which may be, for example, a simple prompt sound effect, which may be, for example, "beep, beep. The present invention is directed to a method for providing a communication device, which includes "a current radiation is large, so as to avoid affecting your health, suggest that you call away from the brain", "the current radiation is large, so as to avoid affecting your health, suggest that you call with a connected earphone" and "the current radiation is large, so as to avoid affecting your health, suggest that you switch an earphone mode", and so on.

(3) Generating a vibration prompt and a sound prompt;

when the terminal 100 performs the VOIP call, if the receiver 170B of the terminal 100 is in the open state and the current transmission power of the terminal 100 is greater than the preset power threshold, the processor 110 of the terminal 100 controls the motor 191 to operate so as to generate vibration, so as to perform a vibration prompt to the user, wherein the time and the vibration mode for generating the vibration can be flexibly set.

Simultaneously or sequentially with the generation of the vibration, the terminal 100 may also generate an audible prompt through the receiver 170B, the audible prompt may be, for example, a simple prompt tone, and the prompt sound effect may be, for example, "beep, beep. The method includes that "current radiation is large, in order to avoid influencing your health, you are advised to talk away from the brain", "current radiation is large, in order to avoid influencing your health, you are advised to talk with a connected earphone" and "current radiation is large, in order to avoid influencing your health, voice prompts such as" you switch earphone mode "are proposed, and of course, the voice prompts listed above are only used as examples and should not limit the embodiment of the present invention.

(4) Generating a vibration prompt and an interface prompt;

when the terminal 100 performs the VOIP call, if the receiver 170B of the terminal 100 is in the open state and the current transmission power of the terminal 100 is greater than the preset power threshold, the processor 110 of the terminal 100 controls the motor 191 to operate so as to generate vibration, and at this time, the processor 110 controls the motor 191 to operate so as to generate vibration, so as to prompt the user to vibrate, wherein the time and the vibration mode for generating vibration can be flexibly set.

While or before the vibration is generated, the terminal 100 may display an interface prompt message through the display screen 194, where the interface prompt message may be as shown in fig. 10(a) -10 (b), and since it is difficult for the user to see the interface prompt message on the display screen 194 when the terminal 100 performs the VOIP call near the head of the user, the vibration prompt may be generated while or before the interface prompt is generated, so that the user sees the display screen 194 of the terminal 100 under the vibration prompt.

The interface prompt information may be, for example:

fig. 10(a) shows that "the current radiation is large, and for the sake of physical health, you are advised to connect a headset for conversation".

Fig. 10(b) shows that "the current radiation is large, and for the sake of physical health, it is recommended to switch the speaker call".

Of course, the above-listed interface prompts are only examples, and should not limit the embodiments of the present invention.

As shown in fig. 8, further, the method for adjusting the transmission power may further include:

step S33: and when the terminal detects that the VOIP call is hung up or the telephone receiver is closed, restoring the adjustment of the transmitting power.

It can be understood that, in this embodiment, when it is determined that the terminal 100 is using the receiver 170B to perform the VOIP call and the current transmission power of the terminal 100 is greater than the preset power threshold, the first prompt information is generated first, and if the first prompt information is generated, and the user is in the preset time range, the terminal 100 is still using the receiver 170B to perform the VOIP call and the current transmission power of the terminal 100 is still greater than the preset power threshold, the current transmission power of the terminal 100 is adjusted, so as to avoid suddenly reducing the transmission power, so that the communication quality is suddenly deteriorated, and the user experience is affected.

Fig. 11 is a flowchart of a transmit power adjustment method according to an embodiment of the present invention.

Referring to fig. 11, an embodiment of the present invention provides a method for adjusting transmit power, applied to a terminal, including:

step S41: when the terminal carries out VOIP conversation, if the receiver of the terminal is detected to be in an open state and the current transmitting power of the terminal is larger than a preset power threshold value, the transmitting power is reduced, and the reduced transmitting power is smaller than or equal to the preset power threshold value;

step S42: and detecting the current VOIP call quality, and generating second prompt information if the current VOIP call quality is unqualified.

Wherein: the detection of the VOIP call quality may be determined by the strength of the voice signal received by the terminal, for example, when the strength of the voice signal received by the terminal is lower than a preset strength and the duration exceeds a second preset duration, the current VOIP call quality is determined to be unqualified, and the second preset duration is, for example, 2 seconds.

Referring to fig. 9 again, in the present embodiment, the terminal 100 includes, but is not limited to, a processor 110, an audio module 170, a speaker 170A, a receiver 170B, an earphone interface 170D, a display screen 194 and a motor 191.

Wherein: the second prompt message may be in the form of one or more of a vibration prompt, a sound prompt and an interface message prompt, wherein the vibration prompt may be generated by the motor 191, and the processor 110 controls the motor 191 to operate, so as to generate vibration; the voice prompt may be generated by the receiver 170B, the processor 110 generates an audio electric signal by controlling the audio module 170, and the receiver 170B converts the audio electric signal into a sound signal; interface information prompts may be displayed via the display screen 194.

Generating the second prompting message may include, but is not limited to, the following:

(1) generating only a vibration prompt;

if the VOIP call quality is unqualified after the transmission power is reduced, a vibration prompt can be generated to prompt a user to switch an earphone or a loudspeaker for calling, wherein the time for generating vibration and the vibration mode can be flexibly set.

(2) Generating only the voice prompt;

if the VOIP quality is not acceptable after the transmit power is reduced, the processor 110 of the terminal may control the receiver 170B to generate an audio prompt, which may be, for example, a simple prompt sound effect, which may be, for example, "beep, beep. The voice prompts such as "call with a poor current signal, suggest that you connect to an earphone, call with a poor current signal, suggest that you switch an earphone mode", and the like, are provided, and of course, the voice prompts listed above are only examples, and should not limit the embodiment of the present invention.

(3) Generating a vibration prompt and a sound prompt;

Simultaneously with or after the generation of the vibration prompt, the terminal may also generate an audio prompt through the receiver 170B, the audio prompt may be, for example, a simple prompt sound, and the prompt sound may be, for example, a "beep, beep. The voice prompts such as "call with a poor current signal, suggest that you connect to an earphone, and" call with a poor current signal, suggest that you switch the earphone mode ", are provided, and of course, the voice prompts listed above are only examples, and should not limit the embodiment of the present invention.

(4) Generating a vibration prompt and an interface prompt;

if the VOIP call quality is not qualified after the transmission power is reduced, the processor 110 of the terminal controls the motor 191 to work so as to generate vibration, at the moment, the processor 110 controls the motor 191 to work so as to generate vibration to prompt a user with vibration, wherein the vibration generating time and the vibration mode can be flexibly set.

While or before the vibration is generated, the terminal may display an interface prompt message through the display screen 194, where the interface prompt message may be as shown in fig. 12(a) -12 (b), and since it is difficult for the user to see the interface prompt message on the display screen 194 when the terminal performs the VOIP call near the head of the user, the vibration prompt may be generated while or before the interface prompt is generated, so that the user may see the display screen 194 of the terminal after the vibration prompt.

The interface prompt information may be, for example:

fig. 12(a) shows that "the current signal is weak, suggesting that the headset is connected for conversation".

Fig. 12(b) "the current signal is weak, suggesting switching of the handset mode".

It can be understood that, in the embodiment, when the terminal is used for carrying out the VOIP call and the terminal is close to the head of the user, the transmission power of the terminal is reduced to reduce the electromagnetic radiation of the terminal in the scene, and simultaneously, after the transmission power of the terminal is reduced, the VOIP call quality is detected, and when the VOIP call quality is unqualified, a prompt is generated for the user, for example, the user is prompted to carry out the VOIP call through an earphone or in a switched earphone mode, so that the use experience of the user can be greatly improved, and the practicability of a terminal product is increased.

As shown in fig. 11, further, the method for adjusting the transmission power may further include:

step S43: and when the terminal detects that the VOIP call is hung up or the telephone receiver is closed, restoring the adjustment of the transmitting power.

It can be understood that, in the embodiment of the present invention, after the transmission power of the terminal 100 is reduced, the VOIP call quality is detected, when the current VOIP call quality is detected to be unqualified, the second prompt information is generated, and after receiving the second prompt information, the user switches to the earphone or the speaker 170A to continue the VOIP call, and at this time, the transmission power is recovered, which can ensure that the radiation does not affect the human body, and also ensure that the VOIP call quality is not affected, and the reliability is strong, and the practicability is high.

In some scenarios, for example, in a scenario where the user must use the receiver 170B currently, if the user does not carry an earphone and is inconvenient to turn on the speaker 170A, the user may not respond to the second prompt message of the terminal 100 and continue to use the receiver 170B for the VOIP call, based on the foregoing, in one possible implementation manner, the transmit power adjustment method may further include:

step S44: if the terminal does not detect that the VOIP call is hung up or the receiver is closed within a third preset time after the second prompt message is generated, and the VOIP call quality is not qualified when the third preset time is reached, increasing the transmitting power, and detecting whether the VOIP call quality is qualified again;

step S45: if not, continuing to increase the transmission power, and repeating the steps until the VOIP call quality is detected to be qualified, or until the increased transmission power accumulation reaches a first set threshold, or until the transmission power of the terminal reaches a second set threshold, or until the times of increasing the transmission power reaches a third preset threshold;

step S46: if so, the increase of the transmission power is stopped.

Preferably, in order to better fit practical applications, in the embodiment of the present invention, the value of the transmit power increased by each time of the terminal is the same, for example, the transmit power increased by each time is increased by 0.2dBm, and generally, the transmit power increased by each time is much smaller than the transmit power decreased in step S41.

It should be noted that, assuming that the terminal increases the transmission power N times (N is a natural number greater than or equal to 1) in steps S44 and S45, the cumulative value of the increased transmission power N times is generally smaller than the transmission power decreased in step S41, and therefore, the cumulative value of the increased transmission power is limited by the above first set threshold or the second set threshold or the transmission power reached after the increase is limited, so that the quality of the VOIP conversation is guaranteed as much as possible on the premise of reducing the radiation. Of course, in the case where it is necessary to ensure that the quality of the VOIP call is qualified, the cumulative value of the transmission power increased in steps S44 and S45 may also be greater than or equal to the transmission power decreased in step S41, and the terminal 100 does not stop increasing the transmission power until the VOIP call quality is detected to be qualified, so that the quality of the VOIP call can be ensured to be qualified while avoiding the transmission power from being excessively large.

In another possible implementation manner of the present invention, in step S42, it may be unnecessary to generate the second prompt message, in step S42, if the current VOIP call quality is not qualified, the second prompt message may not be generated, and the processing of increasing the transmission power is directly performed, and after increasing the transmission power, whether the VOIP call quality is qualified is detected again; and if the call quality is unqualified, continuing to increase the transmission power, and repeating the steps until the call quality is detected to be qualified, or until the accumulated increased transmission power reaches a first set threshold, or until the transmission power of the terminal reaches a second set threshold, or until the times of increasing the transmission power reaches a third preset threshold. If qualified, the increase of the transmission power is stopped, so as to reduce the transmission power (reduce radiation) as much as possible under the condition of ensuring that the quality of the VOIP call is qualified.

Fig. 13 is a schematic structural diagram of a terminal according to an embodiment of the present invention.

The embodiment of the present application also discloses a terminal 400, and it should be understood that the terminal 400 can perform various steps in the transmission power adjustment method, and details are not described here to avoid repetition. As shown in fig. 13, the terminal 400 includes:

It can be understood that, by designing the above scheme for controlling the transmission power in the VOIP call, when the user uses the terminal 400 to perform the VOIP call and the terminal 400 is close to the head of the user, the transmission power of the terminal 400 is adjusted to reduce the electromagnetic radiation of the terminal 400 in this scenario, and reduce the influence on the body of the user.
