Description

Method for controlling alarm information for a mobile terminal {Method for controlling a alarm information for a mobile telecommunications terminal}

The present invention relates to a method for managing alarm information for a mobile communication terminal. More specifically, in addition to the existing "alarm setting process", a series of "alarm sound repetition time setting process" is further implemented, and a series of " The alarm sound management method is described in detail in the conventional "simple key operation process" from the "simple key operation process" to the alarm information management method for the mobile communication terminal which maximizes the utility of the "repetitive alarm function".

In recent years, as the spread of mobile communication terminals has increased rapidly, these mobile communication terminals have additional functions as disclosed in, for example, Korean Patent Laid-Open Publication No. 2000-13712, "Method for generating an improved alarm sound for a mobile phone". For example, an "alarm sound generating function" is added.

If such a "alarm sound generation function" is added to any mobile communication terminal, the user may not receive a specific time, for example, appointment time, wake up time, meeting time, etc., without a separate alarm device. It's easy to see.

In recent years, as the use of mobile communication terminals has increased more rapidly, for example, Korean Patent Publication No. 2000-24439, "Alarm Clock which executes a function set by a user when setting an alarm", Korean Utility Model Publication No. 2000-197269 A series of "repetitive alarm functions" as described in "Alarm Clock with Digital Recorder Function that Outputs Sleep Message When Setting Alarm Function (Setting or Disabling an Alarm at a Set Time)". In this regard, efforts to add a new "repeat alarm function" to the existing "alarm sound generation function" have been accelerated.

If the "repeat alarm function" is implemented in the mobile communication terminal, the alarm sound that has begun to be output once is repeatedly output at a predetermined time interval unless the user takes a series of "complete release actions". In this case, for example, the user who is sleeping may be able to wake up easily from the bed only with an additional function of the mobile communication terminal without using an expensive "morning call service".

However, in the conventional " repeat alarm process " as shown in the above-mentioned 24439 patent, 197269 patent, etc., since the repetition time of the alarm sound is generally set unilaterally in advance by the manufacturer, it is necessary to purchase the product later. The user cannot adjust the "repetition time of the alarm" appropriately for his habit or life-time, and in the end, the user cannot elastically enjoy the "repeating alarm function" to his taste. do.

In addition, in the case of the conventional "repeat alarm process", since the "release action process" of the alarm sound is extremely simple, the user can easily release the "repeat alarm function" by only one or two key operations. If the user who is used to the operation is unconsciously dismissing the notification sound completely, and the notification sound cannot be repeated anymore, for example, the user who is in bed is forced to see a large frustration while using the "repeat alarm function". Therefore, the "repetitive alarm function" cannot be effectively enjoyed.

If these problems are not solved in advance, it is not possible to smoothly add a "repeat alarm function" to the mobile communication terminal. Even if the "repeat alarm function" is added to the mobile communication terminal, the mobile communication terminal has a certain level. The above quality improvement cannot be achieved.

Accordingly, an object of the present invention is to implement a series of "alarm tone repetition time setting process" in addition to the conventional "alarm setting process", thereby allowing any user to fit his habit or life-time. By allowing the user to freely adjust the repetition time of the alarm, the user can induce the user to enjoy the "repeat alarm function" flexibly according to his or her taste.

It is another object of the present invention to detail a series of "alarm release measures" from the conventional "simple key manipulation process" to "user specific information answering process", whereby the user does not completely cancel the alarm sound unconsciously. By blocking it in advance, the utility of the "repeat alarm function" is maximized.

It is still another object of the present invention to solve the above-described problems of the conventional "repeat alarm process" through the "automatic control of alarm repetition time", "detail of alarm release process", and the like. Function "is intended to be added to the mobile communication terminal without any difficulty.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In the present invention to achieve the above object in the alarm information management method of a mobile communication terminal having a series of input and output gates exposed to any user side, when a series of repetitive alarm setting event occurs from the input gate Transmitting a series of alarm repeating time setting guide messages to the output gate to receive a desired alarm repeating time; Storing alarm information when the alarm repetition time setting information corresponding to the alarm repetition time setting guide message is input from the input gate and reflecting the corresponding information in an execution routine of the repetitive alarm; Checking previously stored alarm setting details and extracting a preset alarm sound when the alarm output time arrives and outputting the corresponding alarm sound to the output gate; Determining whether alarm sound pause information for pausing the output of the alarm sound is input from the input gate; When the alarm sound pause information is transmitted from the input gate, the output of the alarm sound is suspended and the stored alarm repeat time setting information is checked to check whether a series of alarm repeat times have arrived. Steps; When the alarm repeat time arrives, the alarm information management method for a mobile communication terminal comprising a combination of the step of extracting the alarm sound again and outputs the alarm sound to the output gate is disclosed.

Hereinafter, an alarm information management method for a mobile communication terminal according to the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the mobile communication terminal 100 in which the present invention is implemented includes a main body 101 including a series of output gates, for example, a speaker 104, a display window 106, and the like. The terminal control unit 10 embedded in the main body 101, the duplexer 60 forming a series of signal connection relationships with the terminal control unit 10, the signal transmitting unit 50, the frequency combining unit 40, the signal receiving unit ( 30) and a combination of the alarm information management module 70 and the like unique to the present invention forming another signal connection relationship with the terminal control unit 10 above.

In this case, the duplexer 60 outputs a signal received by the antenna 103 to the signal receiver 30, or outputs a signal output from the signal transmitter 50 to the outside through the antenna 103. The signal receiver 30 synthesizes a signal output from the duplexer 60 and a signal output from the frequency synthesizer 40, and then outputs the synthesized signal to the speaker 104.

In addition, the aforementioned frequency synthesizer 40 generates a separate frequency for removing a carrier frequency of a signal received by the frequency synthesizer 40, and outputs the frequency to the signal receiver 30 or transmits a separate frequency. It generates a carrier frequency, and outputs this transmission carrier frequency to the signal transmitter 50, the signal transmitter 50 is an electrical voice signal output from the microphone 102 and the previous frequency synthesizer 40 And synthesizes a transmission carrier frequency output from the digital signal, and outputs the synthesized signal to the duplexer 60.

At this time, the above-described signal transmitter 50, frequency synthesizer 40, signal receiver 30, and the like are all controlled by the aforementioned terminal controller 10, and eventually, the terminal controller 10 receives the signal transmitter. 50, the operation state of the frequency synthesizer 40, the signal receiver 30, and the like can be arbitrarily adjusted.

Here, as shown in the figure, the terminal control unit 10 is not only a signal transmitter 50, a frequency synthesizer 40, a signal receiver 30, but also a data memory 20, an input gate, for example, The key input unit 105 and the like also form a series of signal connection relationships.

In this case, the data memory unit 20 stores a program for performing the overall operation of the device, data generated by the operation of the program, and the like at once, and the key input unit 105 is a key input situation of the user. It serves to deliver to the terminal control unit 10.

On the other hand, as shown in the figure, the alarm information management module 70 unique to the present invention mentioned above is largely, the alarm information storage unit 73, the alarm repeat time storage unit 74, repeated alarm release information storage unit ( 72), the alarm sound storage unit 75, the alarm operation message storage unit 76, the alarm information output controller 71 and the like combination.

At this time, the alarm information storage unit 73 is configured by the user, for example, alarm information set by the user, such as "the alarm tone output time set by the user, the type of alarm sound set by the user, whether or not the repeat alarm set by the user ..." It stores the same information, and the alarm repeat time storage unit 74, the alarm repeat time information set by the user, for example, information such as "an alarm repeat time set by the user is 5 minutes 30 seconds ... And the repeat alarm release information storage unit 72, the information for releasing the repetitive alarm sound, for example, "Password for releasing the repetitive alarm sound, query / answer phrase for releasing the repetitive alarm sound. It stores the information such as ‥‥ ".

In addition, the alarm sound storage unit 75 stores various types of alarm sounds provided by the mobile communication terminal, for example, "alarm sound, alarm sound ....", and the like, and stores the alarm operation message storage unit 76. ) Stores various alarm operation messages required for the alarm information operation process of the alarm information output controller 71.

At this time, the alarm information output controller 71 has a series of signal connection relations with the terminal control unit 10, the alarm information storage unit 73, the alarm repeat time storage unit 74, repeated alarm release information By closely controlling the storage unit 72, the alarm sound storage unit 75, the alarm operation message storage unit 76, and the like, it plays a role of managing and executing the alarm information management process according to the present invention.

Hereinafter, the alarm information management method for a mobile communication terminal according to the present invention will be described in detail.

First, in a state where the menu message 201 as shown in FIG. 2 is displayed in the display window 106 of the main body 101, the alarm information output controller 71, as shown in FIG. By continuously checking the signal transmitted from (10), it is determined whether or not a series of alarm setting events have occurred from the key input unit 105 (step S1).

At this time, if the user does not proceed with the predetermined alarm setting operation, it is determined that no separate alarm setting event has occurred from the key input unit 105, the alarm information output controller 71 does not proceed to a separate step, immediately End the flow.

However, if the user selects the alarm setting item 201a of the menu message 201 and it is determined that a series of alarm setting events have occurred from the key input unit 105, the alarm information output controller 71 immediately exits the preliminary pattern. Proceed with the alarm time / alarm sound setting mode, the user receives the desired alarm time and alarm sound (step S2).

In this state, the alarm information output controller 71 continuously checks the signal transmitted from the terminal controller 10 to determine whether a series of alarm time / alarm tone setting completion events has occurred from the key input unit 105. (Step S3).

At this time, if the user has not yet completed the alarm time / alarm sound setting process, it is determined that a separate alarm time / alarm sound setting completion event has not occurred from the key input unit 105, the alarm information output controller 71 The flow advances to step S4 to maintain a series of standby states.

However, if the user completes all of the pre-patterned alarm time / alarm tone setting process and it is determined that a series of alarm time / alarm tone setting completion events has occurred from the key input unit 105, the alarm information output controller 71 Immediately, the alarm time / alarm tone setting result information selected by the user is quickly transmitted to the alarm information storage unit 73, and it is stably stored (step S5).

When the process of storing the alarm time / alarm setting result information is completed, the alarm information output controller 71 immediately utilizes the alarm operation message storage unit 76 to select whether to set the repeat alarm to the user. "A series of repetitive alarm setting inquiry messages are extracted, and the extracted repetitive alarm setting inquiry message is output to the display window 106 via the terminal control unit 10 (step S6). In this case, the repetition alarm setting inquiry message 202 as shown in FIG. 4 is displayed in the display window 106 of the main body 101.

In this state, the alarm information output controller 71 continuously checks the signal transmitted from the terminal controller 10 to determine whether a series of repetitive alarm setting events have occurred from the key input unit 105 (step S7). ).

At this time, if the user selects "No item 202b" of the repetition alarm setting inquiry message 202 and determines that no recurring alarm setting event has occurred from the key input unit 105, the alarm information output controller ( 71) immediately ends the flow without proceeding to another step.

However, if the user selects "Yes item 202a" of the repetition alarm setting inquiry message 202 and determines that a series of repetition alarm setting events have occurred from the key input unit 105, the alarm information output controller 71 Immediately, the alarm operation message storage unit 76 extracts a series of "alarm repetition time setting guide messages" to "set the desired alarm repetition time setting", and sets the "repeating alarm repetition time" when extraction is completed. The guide message "is outputted to the display window 106 via the terminal control unit (step S8). In this case, the display window 106 of the main body 101 includes a series of alarm repetition time setting guide messages (for example, "setting item 203a" and "modification item 203b") as shown in FIG. 203 is displayed.

In this state, the alarm information output controller 71 continuously checks the signal transmitted from the terminal control unit 10, thereby setting a series of alarm repetition time corresponding to the previous alarm repetition time setting guide message from the key input unit 105. It is determined whether or not information has been input (step S9).

At this time, if the user has not yet completed the alarm repeat time setting process, it is determined that the separate alarm repeat time setting information is not input from the key input unit 105, the alarm information output controller 71 proceeds to the flow to step S10. Proceed and maintain a series of standby states.

However, if the user fills in all the blanks in the alarm repeating time setting guide message 203, selects "setting item 203a", and determines that the series of alarm repeating time setting information has been transmitted from the key input unit 105, The alarm information output controller 71 immediately delivers the alarm repetition time setting information autonomously selected by the user to the alarm repetition time storage unit 74, and stably stores the alarm repetition time setting information. It can be substantially reflected in the execution routine of the recurring alarm that proceeds (step S11).

When the process of storing the alarm repetition time setting information as mentioned above is completed, the alarm information output controller 71 immediately releases the repetitive alarm required for releasing the repetitive alarm execution routine by using the alarm operation message storage unit 76. A series of "repeat alarm release setting guide messages" for receiving the key reference information are extracted, and the extracted repeat alarm release setting guide messages are output to the display window 106 via the terminal control unit 10 ( Step S12). In this case, the display window 106 of the main body 101 includes a series of repeated alarm release setting guide messages (eg, "setting item 204a" and "modification item 204b") as shown in FIG. 204 is displayed.

In this state, the alarm information output controller 71 continuously checks the signal transmitted from the terminal control unit 10, thereby repeating a series of repetitions corresponding to the preceding repeated alarm release setting guide message 204 from the key input unit 105. It is determined whether the alarm release key reference information has been input (step S13).

At this time, if the user has not yet completed the "repeating alarm release key reference information input process", and it is determined that no separate repeated alarm release key reference information is input from the key input unit 105, the alarm information output controller 71 The flow advances the flow to step S14 to maintain a series of standby states.

However, the user fills in, for example, the "password input field, query input field, answer phrase input field", and the like of the repeating alarm release setting guide message 204, and selects the setting item 204a, and the key input unit 105 If it is determined that a series of "repeat alarm release key reference information" has been transmitted, the alarm information output controller 71 immediately sends the repeat alarm release key reference information selected autonomously to the repeat alarm release information storage unit 72. By promptly delivering and stably storing it, the repetition alarm release key reference information can be substantially reflected in the subsequent repetition alarm release routine (step S15).

As described above, in the case of the present invention, in addition to the "alarm setting process", a series of "alarm sound repetition time setting processes" are additionally implemented, so that any user can repeat the "alarm repetition" to suit his habit or life-time. Time "can be freely adjusted, and, in the end, the user can enjoy the" repeat alarm function "flexibly according to his or her taste.

When the present invention is implemented, since "autonomous adjustment of alarm repetition time" is enabled, the mobile communication terminal can be pre-received the basic problems of the conventional "repetitive alarm process", and eventually, a series of " The repeat alarm function "can be added to your processing routine without any difficulty.

On the other hand, through the above-described process, the set alarm repeat time information, repeated alarm release key reference information, etc. is substantially utilized through another embodiment of the present invention as shown in FIG. This will be described in detail.

First, the alarm information output controller 71 continuously checks the alarm setting contents previously stored in the alarm information storage unit 73 to determine whether a series of alarm output times has arrived (step S21). .

At this time, if it is determined that the alarm output time has not yet arrived, the alarm information output controller 71 advances the flow to step S22 to maintain a series of standby states.

However, if it is determined that a series of alarm output times previously designated by the user has arrived, the alarm information output controller 71 immediately utilizes the alarm sound storage unit 75 to generate a predetermined alarm sound, for example, by the user. , And extracts the alarm sound, alarm sound, and the like, and outputs the extracted alarm sound to the speaker 104 via the terminal controller 10 (step S23). According to the output of the alarm sound, the user can easily grasp that the specific time designated by the user, for example, the wake-up time, has arrived.

In this state, the alarm information output controller 71 continuously checks the terminal control unit 10, so that the alarm sound pause information is input from the key input unit 105 to "pause the output of the alarm sound". (Step S24).

At this time, if it is determined that the user does not take any action and the separate alarm sound pause information is not input from the key input unit 105, the alarm information output controller 71 proceeds to the flow in step S25, and a series of alarms is performed. The sound output is maintained continuously.

However, if the user randomly presses any key arranged in the key input unit 105, for example, and it is determined that a series of alarm sound pause information is input from the key input unit 105, the alarm information output controller 71 Immediately, the output of the alarm sound is suspended (step S26).

In this state, the alarm information output controller 71 checks the alarm repetition time setting information previously stored in the alarm repetition time storage unit 74 to determine whether a series of alarm repetition time has arrived (step S27). ).

At this time, if it is determined that the alarm repetition time has not yet arrived, the alarm information output controller 71 returns the flow to the previous step S26 to maintain a series of "alarm sound output stop states".

However, if it is determined by the user that the preset alarm repetition time has arrived, the alarm information output controller 71 immediately utilizes the alarm sound storage unit 75, and the alarm sound, alarm sound, etc. previously designated by the user. Is extracted again and the extracted alarm sound is repeatedly outputted to the speaker 104 via the terminal control unit 10 (step S28). According to the repetitive output of the alarm sound, the user may once again be reminded that the alarm time specified by the user has arrived. In this case, the alarm output message 301 as shown in FIG. 8 is displayed in the display window 106 of the main body 101.

In this state, the alarm information output controller 71 continuously checks the terminal control unit 10 to determine whether a series of repeated alarm release events have occurred from the key input unit 105 in order to release the previous " repeat alarm sound ". It is judged whether or not (step S29).

At this time, if it is determined that the user does not take any action and the repetition alarm release event does not occur from the key input unit 105, the alarm information output controller 71 proceeds to the flow in step S30, and a series of alarm sounds Maintain output status continuously.

However, if the user selects the repetitive alarm release item 301a of the alarm output message 301 and determines that a series of repetitive alarm release events have occurred from the key input unit 105, the alarm information output controller 71 immediately proceeds. By using the alarm operation message storage unit, a series of "repeat alarm release key information input request message" for receiving a predetermined "repeat alarm release key information" required for output of the repeated alarm is extracted, and the extraction is completed. The release key information input request message is outputted to the display window 106 via the terminal control unit 10 (step S31). In this case, the repeated alarm release key information input request messages 302 and 303 as shown in FIG. 9 or 10 are displayed in the display window 106 of the main body 101.

In this state, the alarm information output controller 71 continuously checks the signal transmitted from the terminal control unit 10, so that the sequence corresponding to the previous repeated alarm release key information input request message 302,303 from the key input unit 105 is received. It is judged whether or not the repetitive alarm release key information has been input (step S32).

At this time, if the user has not yet completed the "repeating alarm release key information input process" and it is determined that no separate repeated alarm release key information is input from the key input unit 105, the alarm information output controller 71 flows. Proceed to step S33 to maintain a series of standby states.

However, the user fills all of the repeated alarm release key information input request messages 302 and 303, for example, the password input field 302a and the answer input field 303a, selects the confirmation items 302b and 303b, and then enters the key input unit 105. If it is determined that a series of repetitive alarm release key information is inputted from the alarm information output controller 71, the alarm information output controller 71 immediately extracts " repeat alarm release key reference information " stored in the repetitive alarm release information storage unit 72. The "repeat alarm release key reference information" and the currently input "repeat alarm release key information" are compared with each other, whereby the "repeat alarm release key reference information" and "repeat alarm release key information" match with each other. It is judged whether or not to do so (step S34).

At this time, when the "repeat alarm release key information" input by the user does not match the previously stored "repeat alarm release key reference information", the alarm information output controller 71 immediately proceeds to step S35, In addition to outputting a series of error messages to the display window 106 of the main body, the process proceeds to step S30 again to maintain a series of alarm sound output states.

However, when the " repeat alarm release key reference information " input by the user coincides with the previously stored " repeat alarm release key reference information ", the alarm information output controller 71 immediately releases the output of the repeat alarm. Then, the series of alarm output processes according to the present invention is completed (step S36).

As described above, in the case of the present invention, since the " alarm tone release action process " is detailed in the conventional " simple key operation process " as the " user unique information question and answer process " Can not be released, after all, the user can easily obtain the effect of maximizing the effectiveness of the "repeat alarm function".

When the present invention is implemented, since the "detail of the alarm sound release process" is achieved, the mobile communication terminal can be pre-determined the basic problems of the conventional "repeat alarm process", and eventually, a series of "repeats". "Alarm function" can be added to your processing routine without any difficulty.

Thereafter, whenever the alarm output time arrives, the alarm information output controller 71 continuously repeats each of the aforementioned steps, so that the user can effectively enjoy a series of "repeat alarm functions".

As described in detail above, in the present invention, in addition to the existing "alarm setting process", a series of "alarm tone repetition time setting processes" are further implemented. In the "Simple key operation process", the details are referred to as "user unique information question and answer process".

In this case, any user can freely adjust the "alarm repetition time" to suit his habit or life-time, so that the user can enjoy the "repetitive alarm function" flexibly to his taste. Since the alarm sound cannot be released in the unconscious state, the effect of maximizing the utility of the "repeat alarm function" can be easily obtained.

When the present invention is implemented, since the "autonomous adjustment of alarm repetition time" is enabled, and the "detail of the alarm release process" is achieved, the mobile communication terminal has a conventional "repeat alarm process". Basic problems can be pre-empted, and eventually, a series of "repeat alarms" can be added to your processing routine without any difficulty.

The present invention is not limited to the above-described mobile communication terminal, but has an overall useful effect in various electronic devices employing an alarm function.

This invention can be variously modified depending on the situation.

For example, in the present invention, the previous alarm sound may be replaced by vibration, and the repeated alarm release information may be arbitrarily set at the initial production point of the mobile communication terminal without user involvement, and the set repeat alarm release information may be used by the user. You can also provide it separately.

While specific embodiments of the invention have been described and illustrated above, it will be apparent that the invention may be embodied in various modifications by those skilled in the art. Such modified embodiments should not be understood individually from the technical spirit or point of view of the present invention and such modified embodiments should fall within the scope of the appended claims of the present invention.
