In order to facilitate understanding of the embodiments of the present invention, a communication network system on which the mobile terminal of the present invention is based is described below.

Referring to fig. 2, fig. 2 is an architecture diagram of a communication Network system according to an embodiment of the present invention, where the communication Network system is an LTE system of a universal mobile telecommunications technology, and the LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and an IP service 204 of an operator, which are in communication connection in sequence.

The E-UTRAN202 includes eNodeB2021 and other eNodeBs 2022, among others. Among them, the eNodeB2021 may be connected with other eNodeB2022 through backhaul (e.g., X2 interface), the eNodeB2021 is connected to the EPC203, and the eNodeB2021 may provide the UE201 access to the EPC 203.

Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above terminal hardware structure and communication network system, the present invention provides various embodiments of the method for outputting the prompt tone by the terminal.

The invention provides a method for outputting a prompt tone by a terminal.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for outputting a warning tone by a terminal according to a first embodiment of the present invention.

In the present embodiment, an embodiment of a method for a terminal to output an alert tone is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.

In this embodiment, the method for the terminal to output the alert tone includes:

step S10, when detecting that the mobile terminal outputs a warning tone, the mobile terminal transmits a first doppler signal through the doppler transmitting device, and receives a second doppler signal returned after the first doppler signal and the obstacle move relative to each other through the doppler receiving device.

In the mobile terminal, the output time and output volume of the current alert tone have been previously set by the user. And when the mobile terminal detects that the current time is equal to the output time, the mobile terminal outputs a prompt tone according to the preset output volume. The alert tones include, but are not limited to, an alarm, an incoming call alert tone, and a memo alert tone. It can be understood that, in the process of outputting the alert tone, the mobile terminal outputs the alert tone according to the alert tone tracks set by the user, for example, the user can set favorite music as the alert tone. And when the mobile terminal detects that the current time is equal to the output time, the mobile terminal outputs music set by the user in a prompt tone mode.

When the mobile terminal outputs the prompt tone, the mobile terminal sends a first Doppler signal through the Doppler transmitting device and receives a second Doppler signal returned after the first Doppler signal and the barrier move relatively through the Doppler receiving device. In this embodiment, in order to save the cost of the mobile terminal, the receiver of the mobile terminal may be used as the doppler transmitting device, and the microphone of the mobile terminal may be used as the doppler receiving device. Specifically, referring to fig. 4, fig. 4 is a schematic diagram of a mobile terminal transmitting a doppler signal through an earpiece and receiving the doppler signal through a microphone according to an embodiment of the present invention. In other embodiments, a doppler transmitting device dedicated to transmitting doppler signals and a doppler receiving device dedicated to receiving doppler signals may be provided in the mobile terminal. It can be understood that when the user's hand is used as an obstacle, the user's hand is continuously approaching the mobile terminal, and there is a relative motion between the mobile terminal and the obstacle, which generates a doppler effect.

In step S20, a transmission amplitude corresponding to the first doppler signal is determined, and a reception amplitude corresponding to the second doppler signal is determined.

After the mobile terminal transmits the first Doppler signal through the Doppler transmitting device, the mobile terminal records the Doppler transmitting amplitude corresponding to the first Doppler signal. And after the mobile terminal receives the second Doppler signal through the Doppler receiving device, the mobile terminal records the Doppler receiving amplitude corresponding to the second Doppler signal. It can be understood that, after the doppler transmitting device transmits the first doppler signal, if the first doppler signal encounters an obstacle moving relatively during transmission and returns, the doppler receiving device receives the second doppler signal corresponding to the first doppler signal. It should be noted that, when the first doppler signal encounters an obstacle moving relatively and returns, the transmission amplitude of the doppler signal is changed, that is, the transmission amplitude corresponding to the first doppler signal is not consistent with the reception amplitude corresponding to the second doppler signal.

In step S30, an amplitude difference between the transmission amplitude and the reception amplitude is calculated.

And step S40, if the amplitude difference is larger than the preset amplitude difference, the mobile terminal is forbidden to execute the output operation of outputting the prompt tone.

After the mobile terminal determines the transmitting amplitude and the receiving amplitude, the mobile terminal calculates an amplitude difference between the transmitting amplitude and the receiving amplitude, and compares the calculated amplitude difference with a preset amplitude difference. If the amplitude difference is larger than the preset amplitude difference, the mobile terminal prohibits executing the output operation of outputting the currently output prompt tone so as to end outputting the currently output prompt tone. It will be appreciated that the greater the received amplitude, the closer the obstacle is moving to the mobile terminal. The preset amplitude difference may be set according to a personal operation habit of a user, and is not limited herein. In this embodiment, a default amplitude difference set according to the operation habit of the general user is set in the mobile terminal. If the mobile terminal user does not set the amplitude difference, the mobile terminal will use the default amplitude difference as the preset amplitude difference to judge whether to prohibit outputting the currently output prompt.

For example, in the morning, when the user is not at bed, the mobile terminal alarm rings, and the user does not want to open eyes to turn off the alarm at this time. The user can control the mobile terminal to stop ringing by taking a hand as an obstacle under the condition of not clicking a stop button of the mobile terminal to stop ringing through the Doppler signal. Specifically, referring to fig. 5, the user does not need to slide down to turn off the alarm clock, and can turn off the alarm clock directly through doppler without contacting the mobile terminal.

Further, the method for the terminal to output the prompt tone further comprises the following steps:

step a, judging whether the amplitude difference is larger than a preset amplitude difference.

And b, if the amplitude difference is smaller than or equal to the preset amplitude difference, acquiring the transmitting time of transmitting the first Doppler signal and acquiring the receiving time of receiving the second Doppler signal.

Further, after the mobile terminal calculates the amplitude difference between the transmitting amplitude and the receiving amplitude, the calculated amplitude difference is compared with a preset amplitude difference, and whether the calculated amplitude difference is greater than the preset amplitude difference is judged. If the calculated amplitude difference is greater than or equal to the preset amplitude difference, the mobile terminal acquires the transmitting time of the Doppler transmitting device for transmitting the first Doppler signal and acquires the receiving time of the Doppler receiving device for receiving the second Doppler signal. It should be noted that, when the doppler transmitting device transmits the first doppler signal, if the doppler transmitting device can implement the timing function, the doppler transmitting device may record the transmitting time of the first doppler signal, or a timer in the mobile terminal may record the transmitting time of the first doppler signal transmitted by the doppler transmitting device. It is understood that the principle of recording the receiving time of the second doppler signal is consistent with the principle of recording the transmitting time of the first doppler signal, and the description thereof is omitted here.

And c, calculating the sum of the transmission distances of the first Doppler signal and the second Doppler signal according to the transmission time, the receiving time and the transmission rate of the Doppler signals.

And after the mobile terminal acquires the transmitting time and the receiving time, the mobile terminal calculates the time difference between the transmitting time and the receiving time, and calculates the sum of the transmission distances of the first Doppler signal and the second Doppler signal according to the calculated time difference and the transmission rate of the Doppler signals. When the Doppler signal is an ultrasonic signal, the transmission speed of the ultrasonic signal in the air is 340m/s (meters per second). The sum of the transmission distances of the first doppler signal and the second doppler signal is: l ═ C × T, where T denotes the time difference between the transmission time and the reception time, and C denotes the transmission rate of the doppler signal in the air.

And d, if the calculated transmission distance is less than or equal to the preset distance, replacing the track of the prompt tone currently output by the mobile terminal.

After calculating the sum of the transmission distances of the first doppler signal and the second doppler signal, the mobile terminal determines whether the transmission distance (which is the sum of the transmission distances of the first doppler signal and the second doppler signal) is less than or equal to a preset distance. And if the transmission distance is less than or equal to the preset distance, the mobile terminal replaces the currently output track of the prompt tone. Wherein the preset distance can be set by a user as required. And when the user does not set the preset distance, the mobile terminal adopts the default distance as the preset distance. The track of the prompt tone can be preset by the user according to hobbies. In the present embodiment, a prompt tone file library is provided in the mobile terminal, and a file that the user wants to set as a prompt tone is stored in the file library. If the file library stores A, B, C, D and E files for 5 different tracks, as shown in FIG. 6, the 5 files can be all favorite music pieces of the user. If the currently output prompt tone is the B track, when the transmission distance is less than or equal to the preset distance, the mobile terminal replaces A, C, D the currently output prompt tone from the B track and any one of the E tracks. Furthermore, the user can set the output priority of the prompt tones of different songs, and preferentially output the songs with high priority when the prompt tones are replaced and the songs are output.

Further, if the transmission distance is greater than the preset distance, the mobile terminal continues to output the current song with the current output volume.

In the embodiment, after the mobile terminal is detected to output the prompt tone, the first Doppler signal is transmitted through the Doppler transmitting device, and the second Doppler signal returned after the first Doppler signal and the barrier move relatively is received through the Doppler receiving device; determining a transmitting amplitude corresponding to the first Doppler signal and determining a receiving amplitude corresponding to the second Doppler signal; calculating an amplitude difference between the transmit amplitude and the receive amplitude; and if the amplitude difference is larger than the preset amplitude difference, prohibiting the mobile terminal from executing the output operation of outputting the prompt tone. When the user is inconvenient to control the mobile terminal to finish outputting the prompt tone before the output time is reached by clicking the stop button corresponding to the prompt tone in the mobile terminal, the user can use the hand as an obstacle to control the mobile terminal to finish the output operation of outputting the prompt tone before the output time of the prompt tone is reached through the Doppler signal under the condition of not contacting the mobile terminal.

Further, a second embodiment of the method for outputting the alert tone by the terminal of the present invention is proposed based on the first embodiment. The second embodiment of the method for the terminal to output the alert tone is different from the first embodiment of the method for the terminal to output the alert tone in that, referring to fig. 7, the step S40 includes:

in step S41, if the amplitude difference is greater than the preset amplitude difference, the transmitting frequency corresponding to the first doppler signal is obtained, and the receiving frequency corresponding to the second doppler signal is obtained.

If the calculated amplitude difference is larger than the preset amplitude difference, the mobile terminal acquires the transmitting frequency corresponding to the first Doppler signal and acquires the receiving frequency corresponding to the second Doppler signal. Specifically, when the doppler transmitting device transmits a first doppler signal, the mobile terminal controls the doppler transmitting device to record a transmitting frequency corresponding to the first doppler signal; when the doppler receiving device receives the second doppler signal, the mobile terminal controls the doppler receiving device to record the receiving frequency corresponding to the second doppler signal.

In step S42, a frequency difference between the transmission frequency and the reception frequency is calculated.

In step S43, if the frequency difference is greater than the preset frequency difference, the mobile terminal is prohibited from performing an output operation for outputting a prompt tone.

After the mobile terminal acquires the transmitting frequency and the receiving frequency, the mobile terminal calculates a frequency difference between the transmitting frequency and the receiving frequency, and compares the calculated frequency difference with a preset frequency difference. And if the frequency difference is larger than the preset frequency difference, the mobile terminal prohibits executing the output operation of outputting the prompt tone. The preset frequency difference may be set by the user according to specific needs. If the user does not set the preset frequency difference, the mobile terminal adopts the prestored default frequency difference as the preset frequency difference.

and e, judging whether the frequency difference is larger than the preset frequency difference.

And f, if the frequency difference is less than or equal to the preset frequency difference, reducing the output time of the mobile terminal for outputting the prompt tone.

And after the mobile terminal calculates and obtains the frequency difference between the transmitting frequency and the receiving frequency, the mobile terminal judges whether the frequency difference is greater than the preset frequency difference. If the frequency difference is smaller than or equal to the preset frequency difference, the mobile terminal reduces the output time of the output prompt tone. It should be noted that the amplitude of the output time reduction of the mobile terminal may be set according to the total output time of the alert tone, for example, the output time of the alert tone is reduced to half of the total output time, or the output time of the alert tone is reduced to three-quarters of the total output time, and the specific output time reduction amplitude is not limited in this embodiment.

In the embodiment, after the amplitude difference is greater than the preset amplitude difference, the frequency difference between the receiving frequency and the sending frequency is determined, only when the frequency difference is also greater than the preset frequency difference, the mobile terminal is prohibited from executing the output operation of the output prompt tone, and whether the mobile terminal is prohibited from executing the output operation of the output prompt tone is determined by the amplitude and the frequency, so that the accuracy of the output prompt tone of the terminal is improved.

Further, a third embodiment of the method for outputting the alert tone by the terminal of the present invention is provided. The third embodiment of the method for the terminal to output the alert tone is different from the first and/or second embodiment of the method for the terminal to output the alert tone in that, referring to fig. 8, the method for the terminal to output the alert tone further includes:

in step S50, it is determined whether the amplitude difference is greater than a predetermined amplitude difference.

In step S60, if the amplitude difference is smaller than or equal to the preset amplitude difference, the transmitting time for transmitting the first doppler signal is obtained, and the receiving time for receiving the second doppler signal is obtained.

Step S70, calculating the sum of the transmission distances of the first doppler signal and the second doppler signal according to the transmission time, the reception time, and the transmission rate of the doppler signal.

In step S80, if the calculated transmission distance is less than or equal to the preset distance, the output volume of the mobile terminal for outputting the alert tone is decreased.

And after the mobile terminal calculates and obtains the amplitude difference between the receiving amplitude and the transmitting amplitude, the mobile terminal judges whether the amplitude difference is larger than a preset amplitude difference. If the calculated amplitude difference is larger than the preset amplitude difference, the mobile terminal acquires the transmitting time for transmitting the first Doppler signal and acquires the receiving time for receiving the second Doppler signal. And the mobile terminal calculates the sum of the transmission distances of the first Doppler signal and the second Doppler signal according to the acquired transmission time, the acquired reception time and the acquired transmission rate of the Doppler signals. And when the calculated Doppler transmission distance is smaller than or equal to the preset distance, the mobile terminal reduces the output volume of the output prompt tone. Specifically, the amplitude of the mobile terminal for reducing the output volume may be set according to specific needs, for example, the mobile terminal may be set to reduce the volume of one unit based on the original output volume, or reduce the volume of two units.

and g, judging whether the transmission distance is greater than a preset distance.

And h, if the transmission distance is greater than the preset distance, controlling the mobile terminal to output a prompt tone at the current output volume.

Further, after the mobile terminal calculates the transmission distance, the mobile terminal determines whether the transmission distance is greater than a preset distance. If the transmission distance is greater than the preset distance, the mobile terminal controls the mobile terminal to continue outputting the prompt tone at the current output volume.

According to the embodiment, when the amplitude difference is determined to be smaller than or equal to the preset amplitude difference and the transmission distance of the first Doppler signal is smaller than or equal to the preset distance, the output volume of the mobile terminal for outputting the prompt tone is reduced, and the output volume of the intelligent terminal for outputting the prompt tone is realized under the condition that the intelligent terminal is not in contact with the mobile terminal.

Further, a fourth embodiment of the method for outputting the alert tone by the terminal of the present invention is provided. The fourth embodiment of the method for the terminal to output the alert tone is different from the first, second and/or third embodiment of the method for the terminal to output the alert tone in that, referring to fig. 9, the method for the terminal to output the alert tone further includes:

step S90, calculating the number of times of prohibiting the mobile terminal from performing the output operation, and obtaining the output time and output volume of each output operation.

The mobile terminal calculates the number of times of forbidding the execution of the output prompt tone output operation through the Doppler signal, and correspondingly acquires the output time and the output volume of each output operation, namely acquires the output time and the output volume corresponding to the prompt tone when the output of the prompt tone through the Doppler signal is finished. If a plurality of output volumes exist before the prompt tone is output at a certain time, the output volume acquired by the mobile terminal is the average output volume of the plurality of output volumes.

In step S110, if the prohibited number is greater than or equal to the preset number, a default output time of the alert tone is set according to the output time, and a default output volume of the alert tone is set according to the output volume.

After the mobile terminal obtains the prohibited times, the mobile terminal judges whether the obtained prohibited times are larger than or equal to the preset times. If the forbidden times are larger than or equal to the preset times, the mobile terminal sets the default output time of the prompt tone according to the acquired output time and sets the default output volume of the prompt tone according to the output volume. The preset times can be set according to specific needs, for example, can be set to 50 times, or 60 times, etc.

Further, if the prohibited number is less than the preset number, the mobile terminal continues to calculate the prohibited number for prohibiting execution of the output operation.

Further, step S110 includes:

and i, if the forbidden times are greater than or equal to the preset times, calculating the average output time within the forbidden times according to the output time, and calculating the average output volume within the forbidden times according to the output volume.

And j, setting the average output time as the default output time of the warning tone, and setting the average output volume as the default output volume of the warning tone.

Further, if the number of times of prohibition is greater than or equal to the preset number of times, the mobile terminal calculates an average output time within the number of times of prohibition according to the obtained number of times of output, and calculates an average output volume within the number of times of prohibition according to the output volume. And after the average output time and the average output volume are calculated by the mobile terminal, setting the average output time as the default output time of the prompt tone and setting the average output volume as the default output volume of the output prompt tone by moving. If the number of times of prohibition recorded by the mobile terminal is 50 times and the preset number of times is also set to 50 times, the mobile terminal obtains the output time and the output volume corresponding to the 50 prompt tones, calculates the average output time of the 50 output times, sets the average output time corresponding to the 50 output times as the default output time of the prompt tone, calculates the average output volume of the 50 output volumes, and sets the average output volume corresponding to the 50 output volumes as the default output volume of the prompt tone.

According to the embodiment, the default output volume and the default output time corresponding to the prompt tone are set according to the operation habit of the user for outputting the prompt tone through the Doppler terminal, so that the default output time and the default output volume of the mobile terminal for outputting the prompt tone are more in line with the operation habit of the user.
