Phone Receipt Mode Conversion Apparatus and Method for Switching to Bell Mode using Mode Change Authentication Information}

The present invention relates to an apparatus and method for converting a reception mode of a telephone terminal in wired / wireless communication, and particularly, when a call reception mode is set to a silent / etiquette mode such as silence or vibration in a destination terminal. When the calling terminal transmits authentication information for mode change to the called terminal for emergency call with the called terminal, if the corresponding authentication information matches the password, family name and caller number managed by the called terminal, the silent mode is recognized as a ringing mode. By switching to easy-to-receive mode, the user who knows the authentication information can efficiently make an emergency call if necessary even with the other party who does not recognize the call reception of the called terminal set to silent mode. High tones from low volume until rejection or call confirmation without switching to ringtone The present invention relates to an apparatus and method for converting a reception mode of a telephone terminal, by which a counterpart of an area where an etiquette is required, such as a public place, can be eliminated by increasing the ring tone level in an amount that can be solved regardless of an intention.

Today, many people around the world are using mobile phone terminals to provide mobile communication services in accordance with mobile communication protocols such as (W) CDMA and GSM. The user can conveniently receive various mobile communication services such as voice call, text message, wireless internet, packet data service, etc. anytime and anywhere using the mobile phone terminal.

In public places where etiquette is required, such as conference rooms, offices, subways, and lecture rooms, users often set the mobile terminal to silent mode (etiquette mode) such as silence or vibration so that others do not interfere with the ringing. However, when a call is received by the terminal set to the silent mode as described above, there is a case where the LED which is flickered when vibrating or silent is not recognized. You can do it. If you're walking around with a lot of ambient noise, or if you're walking around with your device in your pocket or bag, you're more likely not to notice the silent mode.

Even in such a silent mode, a technology for improving the recognition ability of a call request by a ringtone when a call is received by allowing a caller to be switched to a ringtone mode is specifically required.

For example, according to Republic of Korea Patent Application No. 10-2003-27191, if the incoming call attempt from the other party within a predetermined time more than a certain number of times, the terminal outputs a ringtone by automatically switching the reception mode from the vibration mode to the ring mode to the user A configuration is disclosed that enables a user to better recognize call reception. However, in the method of automatically switching the reception mode, the mode is switched only by the number of incoming attempts regardless of the intention of the receiver, so that a call request from an unspecified number of people may be unexpected. There is a problem that can be embarrassed while responding to phone calls in public places where etiquette is required, such as offices, subways, and lecture rooms.

And, according to the Republic of Korea Patent Application No. 10-2004-75994 discloses a configuration to output the ringtone by assigning the caller to the terminal and automatically switching the reception mode from the vibration mode to the ringtone mode when a call request from the caller. However, in such a method of automatic switching of the reception mode, when the transmission is made through a terminal not registered to the destination terminal such as a public telephone or another terminal due to caller circumstances, switching of the reception mode cannot be utilized, so that an emergency call is connected to the other party. There is a problem that is reduced.

In the above automatic reception mode switching method, there is a problem in that the counterpart of the area where etiquette is required has to suffer an inconvenience regardless of the intention by the ringtone, and in the case where the receiver is far from the called terminal or in a noisy area There is also a problem that does not recognize the ringtone easily.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a system 100 in which wired and wireless communication is performed between a calling terminal and a called terminal according to an embodiment of the present invention.

Referring to FIG. 1, in the present invention, as well as voice or video telephone calls between the calling terminal 120 and the called terminal 130 using the wired / wireless communication network 110, a text message, a messenger service, or data available between each other. Services can be supported.

Here, the wired / wireless communication network 110 may be a mobile communication network such as (W) CDMA (Wideband) Code Division Multiple Access (GDMA), Global System for Mobile Telecommunication (GSM), or a line public network such as a public switched telephone network (PSTN). If necessary, it may be extended to the case of a portable Internet network or a satellite network.

The calling terminal 120 and the called terminal 130 mean all terminals capable of wired and wireless communication, and are not only wired telephones but also cellular telephones and PCS phones as wireless communication terminals. phone, synchronous / asynchronous IMT-2000 (International Mobile Telecommunication-2000), and in addition, in some cases, notebook PC, desktop PC, Palm Personal Computer (PDA), Personal Digital Assistant (PDA) , A smartphone, a WAP phone (WAP phone: wireless application protocol phone), mobile play-station (mobile play-station), etc. means all the terminals that can function as a comprehensive.

In the present invention, the originating terminal 120 transmits the authentication information for mode change for the emergency call with the called terminal 130 to the called terminal 130, the corresponding authentication information is managed by the called terminal 130, If the matching information list, such as family name and caller ID, is matched, the call reception mode of silent mode (etiquette mode) such as silent, vibration, LED lamp on / off, etc. is switched to another reception mode such as ringing mode. Family, friends, colleagues, relatives, etc., regardless of the reception mode setting of the destination terminal 130, it was possible to efficiently make an emergency call when necessary. Here, the authentication information may be in the form of a password, a family name, a caller's number, etc. consisting of numbers, letters, and other symbols. When switching from the reception mode to the ring mode, the other party in an area where etiquette is required, such as a public place, is gradually increased from low to high volume until rejection or call confirmation without switching to a loud ringtone from the beginning. Regardless of the intention by this ringtone may be to solve the inconvenience, the emergency call can be made smoothly by allowing the receiver to recognize the ringtone even in a far away or noisy area.

Hereinafter, a method of converting a reception mode of a telephone terminal according to an embodiment of the present invention will be described in more detail with reference to FIG. 2.

First, the user of the called terminal may set the receiving mode of the called terminal to a silent mode (etiquette mode) such as silence, vibration, LED lamp on / off, etc. in a public place where etiquette is required such as a conference room, office, subway, lecture room, etc. S211). Here, the description will be mainly given that the reception mode of the called terminal is the silent mode. However, in some cases, the user may set the reception mode of the called terminal to a mode in which sound is output, such as a ringing mode.

Regardless of which mode the reception mode is set (although mainly in silent mode), when the called terminal is in the standby state (S211), the calling terminal may attempt an emergency call (S220). For example, the user of the calling terminal may enter a telephone number of the called terminal, press a call button, and then use a specific key for attempting an emergency call (for example, a key for selecting an emergency call menu that appears on the screen while listening to a dial tone). , Or press a predetermined key such as *, #, etc.) to make an emergency call, or enter an incoming phone number and press an emergency call button on a terminal prepared separately for an emergency call. It may be.

At this time, although it is optional, when there is an emergency call attempt as described above, the called terminal may determine the reception mode state of the current terminal and notify the calling terminal (S221, S222). For example, depending on the current receiving mode of the called terminal, the calling terminal is "The called terminal is currently in silent mode (silent, vibration, LED lamp on / off, etc.)." Or "The called terminal is currently in ring mode." And the like, and the calling terminal receives the information on whether the current mode of the called terminal is the silent mode or the ringing mode and displays the information on the screen during the call attempt, so that the user of the calling terminal can change the mode. It can help you judge.

On the other hand, when there is an emergency call attempt as described above, that is, when pressing the emergency call button on the calling terminal or pressing a specific key during the call attempt, the authentication information input window may be displayed on the screen of the calling terminal (S230). In this case, the user of the calling terminal may input a password, a family name, a calling party number (telephone terminal number), etc. consisting of numbers, letters, and other symbols as authentication information in the authentication information input window (S231).

The authentication information input as described above may be transmitted to the called terminal by pressing a transmission key at the calling terminal (S240). Accordingly, the called terminal may perform authentication on the authentication information received from the calling terminal (S250). For example, the called terminal can manage a comparison information list (e.g., password, family name, caller ID, etc.) for the conversion of the reception mode to predetermined storage means, and authentication received from the calling terminal in such a list. It may be determined whether the information is included, and if the determination result list does not include the matching information, it may be notified to the calling terminal that the mode change is impossible as an authentication failure message (S251), and match the determination result list. If the information is included, the receiving mode may be automatically changed to another receiving mode that can be easily recognized by the user, such as a ringing mode (S252). For example, the called terminal is changed from the silent mode such as the silent, vibration, LED lamp on / off mode to the ring mode, so that the called terminal notifies the call reception state with the preset ring tone. At this time, the volume level may allow the called terminal to output a ringtone at a preset volume level lower than the maximum volume or lower (S260). In addition, in step S240, the called terminal may receive the volume level set value from the calling terminal together with the authentication information (for example, a method of inputting the volume level in step S231), and accordingly to the received volume level set value Therefore, you can control to output the ringtone at the maximum volume or a lower volume.

In the above, an example in which the reception mode is changed from the silent mode such as the silent mode, the vibration mode, the LED lamp on / off mode, etc. to the ring mode has been described, but the present invention is not limited thereto. It is also possible to change from one of the previously set reception modes of the silent mode, the vibration mode, or the LED lamp on / off mode to the other reception mode of the vibration mode, the LED lamp on / off mode, or the ringtone mode. For example, it is possible to change the reception mode from the silent mode to the LED lamp on / off mode or the ring mode.

Meanwhile, even when the called terminal is notified of the ring mode in step S222, according to the determination result in step S250, the called terminal may be in the ring mode at the request of the calling terminal even when the current mode is already in the ring mode. It is also possible to change. This is for the purpose of gradually increasing the volume or outputting an alarm signal, as described below.

That is, the called terminal switches to the ring mode and starts to notify the call by outputting a specific ring tone at a certain level, and at this time, the time since the time when the ring mode is changed and the dial tone during the call attempt can be counted. There is (S260). Based on the time count value obtained in this manner or the dial tone count value during the call attempt, the called terminal gradually increases the ringer volume level from the initial volume level to the maximum volume level at the time when the call is changed to the ringing mode at the request of the calling terminal. It is possible. Such an increase in the ringer volume level may be continuously performed until the receiving terminal rejects the call or until the call is confirmed. In particular, even if the ringer volume level is increased to the maximum volume level, the reception or rejection of the ringing terminal is increased. If not, the receiving terminal may switch the reception mode to the alarm mode. In alarm mode, a predetermined alarm signal (e.g., a decibel may be higher than the ringtone, a beep sound that makes you feel different from the ringtone, such as a non-musical beep), an alarm lamp on / off (e.g. Periodic on / off of a predetermined LED lamp on a screen, or lighting of a display window (for example, periodic on / off of a display screen).
