Apparatus and method for automatically adjusting arrival of the bell by surrounding noise degree in wireless telecommunication terminal

The present invention relates to a method for automatically adjusting a ringing tone according to the ambient noise level in a wireless communication terminal, and more particularly, by measuring the size of the ambient noise when an incoming call is received in the wireless communication terminal, the ringing tone (received ringing volume) according to the measured size. It is automatically adjusted.

As telephones become popular, they are used in various environments. In particular, with the development of mobile communication, many people use mobile phones and the popularization of wireless phones in the home makes it possible to make calls anytime, anywhere, not only in the house. However, the etiquette of the telephone tends to become more numb as compared to the rapid popularity of the telephone.

In general, the volume control switch is attached to the wired or wireless telephone, so that the user can select the desired volume. That is, if the user sets the switch to a position corresponding to the sound volume deemed appropriate, the ringer volume of the telephone is maintained at the set volume until the user later operates the switch.

By the way, when adjusting the volume control switch, the user determines that the surrounding environment is quiet and sets the bell volume of the phone to be small. However, the surrounding environment becomes noisy, and often the user does not hear the bell volume of the phone. On the other hand, when the ring volume of the telephone is set to a high level, the surrounding environment becomes quiet, and it is often surprised to hear the ringing volume of the telephone. The user may feel uncomfortable when these cases occur.

In other words, mobile phones are used in various places (e.g. public libraries, conference venues, concert halls, churches, theaters, courts, places where quietness is required, etc.) and conditions. The bell volume can be adjusted, but it is inconvenient for the users to adjust the bell volume according to the surrounding situation. Most people fix the bell volume at a certain volume so that the bell The volume control is actually just a useless feature.

Conventionally, when the output intensity of the bell volume is set to the output level of the bell volume from the lowest to the highest sound level, the user sets the bell volume so that the bell volume is output at the lowest sound level at a place where low output is required. In places where a high output is required, the user sets the bell volume to output the highest ringing volume. Therefore, since the volume selection by vibration does not cause any noise around, it is used in places where relatively quietness is required, for example, public libraries, meeting places, and performance halls. In addition, in other places where the noise is severe, the user often does not detect the vibration and thus does not answer the incoming call. The bell volume selection is made by pressing the function key on the keypad to select the volume control, and then selecting the bell volume from the low level 1 level to the high level approximately 4 levels. It is common to choose a high volume. However, in this case, when receiving a call from public transportation, that is, a train or a city bus, the bell volume set in the portable telephone causes excessive noise, causing discomfort to the people around. Especially in places where quietness is required, such as public libraries, conference venues, performance halls, churches, theaters, courts, and educational venues, when the user comes to the phone without inadvertently setting the volume selection to vibrate, the noise is loud to those around them. Along with the damage, there was a problem that can cause concentration and discomfort.

To sum up, conventionally, the bell volume had to be fixed in advance in the terminal. Otherwise, you have to change the ringer volume during the call. Therefore, there was a problem that a predetermined bell volume sounds regardless of the ambient noise level. In addition, the bell is ringing even when he does not want to have a problem that damages others.

The present invention has been proposed to solve the above problems, by measuring the amount of ambient noise when the incoming call in the wireless communication terminal, by automatically adjusting the ringing tone (incoming ring volume) according to the measured size, the surrounding environment An object of the present invention is to provide an automatic ringing tone control device and a method thereof for coping with the problem.

In order to achieve the above object, the present invention provides a method for adjusting a ring tone in a wireless communication terminal, comprising: a first step of checking an output mode of a ring tone when an incoming call is generated; If the output of the ringing sound is set to automatic adjustment according to the result of the first step, the second step of detecting the ambient noise and measuring the magnitude of the noise, and then comparing the detected ambient noise with the reference value (reference noise) ; A third step of outputting the ringing tone with the set lower limit sound intensity according to the staged ringing tone output mode when the comparison result of the second step is less than the reference value (reference noise); A fourth step of outputting the ringing tone with a sound intensity within a set reference value range according to the staged ring tone output mode when the ambient noise is within a reference value (reference noise) range as a result of the comparison in the second step; And a fifth step of outputting the ringing tone with the set upper limit sound intensity according to the stepped ring tone output mode when the ambient noise is greater than the reference value (reference noise) as a result of the comparison of the second step.

In addition, the present invention further comprises a sixth step of outputting the ringing tone vibration according to the selection mode preset by the user, if the ambient noise is less than the reference value (reference noise) as a result of the comparison of the second step. It features.

It is done.

The present invention is to continuously monitor the ambient noise through the microphone to change the intensity of the vibration or ring tone when the incoming call, and while measuring the ambient noise through the microphone, the ringing volume varies depending on the degree of ambient noise when the call comes To control the strength and intensity of the vibration, sometimes under constant noise.

That is, according to the present invention, when the bell of the terminal rings according to the incoming call, the bell volume of the terminal is automatically adjusted according to the surrounding noise level, thereby reducing the noise damage of the bell and promoting the user's convenience.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a wireless communication terminal to which the present invention is applied.

Looking at the conditions to be preceded in the practice of the present invention as follows.

In a known terminal, while the bell volume is fixed in advance by a user's manual operation and the microphone 19 is continuously used while being used only for a call, in the implementation of the present invention, ambient noise upon reception is achieved. In order to vary the ring volume according to the microphone 19 is always operated to detect the ambient noise. Therefore, the wireless communication terminal should always be in the standby state, and when the incoming call microphone 19 detects the ambient noise.

As shown in FIG. 1, a wireless communication terminal to which the present invention is applied includes an RF processor 15 for processing a wireless signal input wirelessly, a radio signal processed by the RF processor 15, and an overall input of the terminal. The controller 10 controls the operation and controls the bell volume of the terminal to be automatically adjusted according to the duration and noise intensity of the ambient sound detected through the microphone 19, and is controlled by the controller 10. It is responsible for the input of various functions and operations of the key input unit 13 for receiving a key value for the mode selection according to the sound intensity, the display unit 14 for outputting the data processed by the control unit 10, the control unit The audio processor 17 converts the digital signal processed by the digital signal into an analog signal, and converts the analog signal output from the audio processor 17 into sound pressure that can be heard by a human. The speaker 18, a microphone 19 that senses the sound intensity of ambient sounds and notifies the controller 10 through the voice processor 17, and the speaker 18 or the vibrator 20 under the control of the controller 10. It includes a ring tone generating unit 16 for generating a ring tone.

The control unit (CPU) 10 of the wireless communication terminal controls the overall operation of the terminal and at the same time controls the ring tone automatic control method according to the ambient noise level according to the present invention. Then, control of various components provided is achieved.

The voice memory 11 stores various voice data.

The memory 12 stores an operation program and a system program of the controller 10, and the operation program and the system program are usually stored in a ROM area included therein and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The memory 12 also includes RAM for temporarily storing data generated during the execution of various operating programs.

The key pad 13 includes a plurality of numeric keys, menu keys, and function keys for performing various functions, and outputs key data to the controller 10 by external operation. That is, the key input unit 13 is a conventional user information input means, and has a plurality of keys suitable for a wireless communication terminal to be applied, such as a plurality of numeric keys and function keys, and if there is an input of each of the provided keys, each of the input keys In this case, the corresponding key data is output to the control unit 10.

The display unit 14 is a display device such as a liquid crystal display (LCD). The display unit 14 displays the state of the wireless communication terminal or the progress of the program under the control of the control unit 10. That is, the overall state of the wireless communication terminal and input user information are displayed.

The RF processor 15 is controlled by the controller 10 and converts a signal output from the controller 10 into a wireless signal. In addition, the RF processor 15 converts the radio signal received through the antenna into a desired signal and outputs it.

The ring tone generator 16 generates a ring tone when the call is received through the speaker 18 or the vibrator 20 under the control of the controller 10, and generates a ring tone through the speaker 18 during a call. .

The voice processor 17 modulates the voice signal input from the microphone 19 and converts the voice signal into voice data, and converts the voice data input from the RF processor 15 and the voice data stored in the voice memory 11 into voice signals. Demodulated to output the audio through the speaker 18.

Then, the process of automatically adjusting the ring tone according to the ambient noise level will be described in more detail.

The microphone 19 for detecting the sound around the wireless communication terminal always detects the sound around the terminal, and outputs the detected signal to the voice processor 17. Then, since the signal detected by the microphone 17 is small, the voice processing unit 17 amplifies it to a predetermined size and digitally converts the amplified detection signal to be input to the control unit 10. A signal having a level value is output to the controller 10. By this operation, the controller 10 always receives a level value corresponding to the sound volume sensed around the wireless communication terminal.

On the other hand, when the incoming call is input through the RF processor 15, the control unit 10 controls the ring tone generating unit 16 according to the automatic ring tone control program according to the ambient noise level according to the present invention to the speaker 18 or the vibration unit Call 20 through the control to ring the ringing tone to notify the user. In this case, the controller 10 notifies the ringing tone when the ambient noise is smaller than the reference noise according to the program, and amplifies the ringing tone according to the difference value when the ambient noise is larger than the reference noise.

2 is a flowchart illustrating an exemplary method for automatically adjusting a ringing tone according to the present invention.

As shown in FIG. 2, the method for automatically adjusting the ringing tone according to the ambient noise level according to the present invention is first set to automatic control whether the output of the ringing tone is set to manual control when the wireless communication terminal generates an incoming call 201. It is determined whether or not (202).

As a result, if the output of the ringing tone is set to manual adjustment, the ringing tone is output with the manually adjusted sound intensity (203). That is, if the user does not input a key value for automatic adjustment and the output of the ringing tone is selected as the manual adjustment, the ringing tone is output with the intensity of the ringing tone manually adjusted in the conventional manner. Of course, if the output of the ring tone is manually set to vibration, the ring tone is output by vibration.

As a result, if the user inputs a key value for auto-adjustment and the output of the ringing tone is set to auto-adjustment, the ambient noise is detected to measure the duration and intensity of the noise (204), and then the detected ambient noise and the reference value are detected. (Reference noise) is compared (205). That is, when the microphone 19 measures the ambient noise and informs the controller 10, the controller 20 calculates the sound intensity of the ambient noise and the duration of the noise. Thus, the duration and sound intensity of the ambient noise can be converted into a numerical value that can be compared with the reference value, and compared with the set reference value.

As a result of the comparison, if the ambient noise is less than the reference value (reference noise), according to the preset selection mode (206), the ringing tone is output as a vibration (207), or the ringing tone output is set to the lower limit in the mode according to the sound intensity (208) The ringing tone is output at the set lower sound level (212). Of course, the process of outputting the ringing tone with the sound intensity of the lower limit represents an example of the process of outputting the ringing tone.

As a result of the comparison, if the ambient noise is greater than or equal to the reference value (reference noise), according to the gradual ring tone output mode (209), if the detected noise is within the reference value range, the ring tone is set to the reference value range in the mode according to the sound intensity (210) The ringing tone is output with the sound intensity within the set reference value range (212). On the other hand, if the detected noise is greater than the reference value range, the ringing tone is set as the upper limit in the mode according to the sound intensity (211) and outputs the ringing tone with the sound intensity of the set upper limit (212).

In the above process, the user inputs the key value for the automatic adjustment and sets the output of the ringing tone to the automatic adjustment in advance, and sets the vibration or the bell mode in advance for the case where the ambient noise is smaller than the reference value (the reference noise). . Of course, if the vibration mode is not set in advance, the bell mode is automatically set to the operation mode.

In the preferred embodiment of the present invention, in setting the output range and reference value range of the incoming call intensity of the mode according to the sound intensity, for example, the mode according to the sound intensity may be a quiet mode (lower limit mode), an intermediate mode, In the noisy mode (upper limit mode), assuming that the output range of the speaker 18 of the wireless communication terminal is from 1 low to 9 high 9, the lower limit is about 1 to 3, the middle mode is about 4 to 6, The upper limit mode can be set between 7 and 9. The reference value range may be set to 5, or may be set to about 4 to 6 which are intermediate modes. At this time, the ring tone output degree of each mode may be set by the user in advance, and if not set in advance, it is automatically set to 2 in the lower limit mode, 5 in the middle mode, and 8 in the upper limit mode.

For example, suppose that the reference value is set to 5, the lower limit output is set to 3, and the upper limit output is set to 7 when the mode according to the sound intensity selected by the user is an intermediate mode. And, if the degree of noise is set to 0dB ~ 100dB, each noise intensity is converted to correspond to 1-9, the ring tone output range.

Thus, when the detected noise is "1 to 3", since the noise is smaller than the reference value range, the ringing tone output from the speaker 18 is output to 3, which is the lower limit. When the detected noise is “4 to 6”, the ringing tone is output to 5 as a reference value. In addition, when the detected noise is "7-9", the incoming call is output to the upper limit of 7.

As such, the present invention can reduce the noise damage of the bell by automatically adjusting the ringing tone according to the ambient noise level when the bell of the terminal according to the ringing.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above, by automatically adjusting the incoming volume according to the noise level when the incoming, reducing the noise damage according to the ring volume, especially in public places, such as when the terminal user is interrupted by a sudden ringtone for work It can reduce the noise harmfulness and can detect the fact that the call is received even when the surrounding noise is strong, thereby increasing the user's convenience.
