Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly to a mobile phone that transmits and receives radio waves to and from a base station.

[0002]

2. Description of the Related Art In a telephone, when an incoming call request signal is detected, a ringing tone based on the signal is generally generated. This ringing tone is called a ringing tone and is generated by giving a signal at a constant frequency to a small speaker called a ringer provided in the telephone body.

In many cases, ringtones produced by such a ringer are prepared in several types with different frequencies. The user selects a desired sound from the ringtones prepared in advance and sets it as a ringtone. This makes it easy to recognize that the telephone used by the user has arrived.

[0004]

The ring tone prepared in advance for such a telephone is limited. In addition, such ringtones prepared in advance often have the same basic oscillating frequency, and each ringtone has only a difference in the length of transmission time and the extent to which the intermittent pattern is changed.

Therefore, it is difficult to distinguish each ring tone, and it is difficult to recognize it immediately if the telephone is not fully used. In particular, in the case of a mobile phone, a plurality of people may carry the phone at the same time while there are an unspecified number of people. In such a case, it is difficult to recognize the ring tone of the other's phone, and even if there is an incoming call to the other person's phone, you must check your own phone every time there is a ring tone. It contains the problem of not becoming.

An object of the present invention is to provide a portable telephone which allows a user to easily determine whether or not his / her own telephone has received an incoming call request signal, based on a ring tone produced when an incoming call arrives. To provide.

[0007]

A portable telephone according to the present invention comprises an incoming call detecting means, an input key section, a setting switching means,
A ring tone storage means, a ring tone generation means, and a transmission / reception means are provided. The incoming call detecting means detects an incoming call request signal from the base station. The input key unit includes a key for making a call and has a plurality of keys for each operation. The mode switching means switches between a normal operation mode and a ring tone setting mode in which a plurality of scales are assigned to the input key section to set the ring tone. The ring tone storage means stores a ring tone set based on an input from the input key unit in the ring tone setting mode. When the incoming call request signal is detected by the incoming call detecting means, the incoming call tone generating means produces a sound based on the incoming call tone stored in the incoming call tone storage means. The transmission / reception means is for transmitting / receiving a call with the other party.

When the ring tone is set, the mode switching means switches the normal operation mode to the ring tone setting mode. At this time, a predetermined sound is assigned to each of the plurality of keys of the input key section, and the user waits for key input. When the input key section is operated and a ring tone is input, this is stored in the ring tone storage means. When the incoming call request signal is detected in the normal operation mode, the incoming call tone stored in the incoming call tone storage means is called, and the incoming call tone generation means emits the incoming call tone. Therefore, the user can independently create and set a ring tone in the ring tone setting mode, and can easily recognize that the telephone set owned by the user has received a call.

The ringing tone generating means can be configured to generate the ringing tone stored in the ringing tone storing means by a speaker for preparing the ringing tone prepared in advance. In this case, the usual mobile phone is equipped with,
By using a so-called ringer, the ringtone set in the ringtone setting mode can be pronounced. The ring tone switching means is further provided, and the ring tone switching means switches the ring tone so that the ring tone generating means selects and sounds the ring tone prepared in advance and the ring tone set in the ring tone setting mode. It can be configured to perform. In this case, the ringtone to be actually pronounced can be selected from a plurality of ringtones.

The mode switching means may be configured to assign a scale to each of the plurality of keys when switching from the normal operation mode to the ring tone setting mode. In this case, the user can input an arbitrary song, and an original song can be composed and set as a ring tone. It is possible to further include a display unit that displays each scale input from the input key unit in the ring tone setting mode. In this case, when the ring tone to be set is input from the key input unit, it can be input while checking the display on the display unit.

Further, it is possible to further comprise a setting confirmation means for confirming the ringtone generated by the ringtone setting mode by the ringtone generation means. In this case, it is possible to check the read ringtone that has been set and readjust it.

Next, the operation of the mobile phone according to the embodiment of the present invention will be described. When the power switch 3 provided on the telephone body 1 is turned on, step S1 in FIG.
At, the parameters in each memory are initialized. In step S2, it is determined whether or not the operation of the ring tone setting mode has been performed. For example, function key 16
When "20" is input from the ten-key pad 14 after ("F / Small"), it is determined that the operation of the ring tone setting mode is performed, and the process proceeds to step S3. In step S3, a ring tone setting process described later is performed.

In step S4, it is determined whether or not the user has made an operation for making a call. Here, when the telephone number of the other party is input from the ten-key pad 14 after the operation of the start key 7 or the registered telephone number is called by the one-touch key 10 or the redial key 9 is operated, the user When it is determined that the calling operation has been performed, the process proceeds to step S5.

In step S5, an incoming call request signal is transmitted to the telephone number designated by the user, and when the other party receives an incoming call, the normal call mode is set. At the time of transmission, the transmission data is transmitted from the transmission unit 39 via the first antenna 37 with the antenna switch 38 set to the transmission side. Step S
At 6, it is judged whether or not an incoming request signal for the own station is detected. Here, the RSSI outputs output from the first reception system 34 and the second reception system 35 are compared, and the reception data on the side with good sensitivity is demodulated by the modulation / demodulation unit 41. When the incoming request signal to the local station is detected in the demodulated received data, the process proceeds to step S7. In step S7,
The ring tone currently selected from the ring tones stored in the EPROM 47 and the EEPROM 48 is called, the ring tone is sounded through the ringer 22, and at the same time, the ring lamp 21 blinks. If the user operates the start key 7, the line is connected and the call is started.

FIG. 6 shows a flowchart of the ring tone setting processing in step S3. In step S11,
A message indicating that the ring tone setting mode is set is displayed on the display 6, and a cursor indicating the position where the sound is input is displayed. For example, as shown in FIG. 8A, "sound setting" is displayed in the mode display area 61 of the display 6, and the cursor 62 is made to blink at the position where the set sound is input. In step S12, it is determined whether or not there is a key input for setting the ring tone. For example, in this ring tone setting mode, if the "1" key of the numeric keypad 14 is assigned to "do", the "2" key is assigned to "re", and the "3" key is assigned to "mi", then "1", When either of the "2" and "3" keys is operated, it is determined that there is a key input for setting the ring tone, and the process proceeds to step S13. Step S1
In 3, the display of the sound corresponding to the key input is displayed on the display 6. For example, it is assumed that the display corresponding to "do" is set to be displayed on the bottom bar, the display corresponding to "re" is displayed on the middle bar, and the display corresponding to "mi" is set to be displayed on the top bar. Now, when the key "1" is operated, FIG.
As shown in (b), the set sound display 64 consisting of a bar indicating the sound of "do" is displayed at the bottom of the input position 63. At the same time, the cursor 62 is moved to the next input position 65. Further, at this time, the corresponding sound is generated by the ringer 20. Further, this sound data is stored in the work area of the RAM 49.

In step S14, it is determined whether or not a correction input has been made. Here, the cursor 62 is moved to the input position on the display 6 where the input has already been completed,
When any one of the "1", "2", and "3" keys is newly operated or when the clear key 15 is operated, it is determined that the correction input is made, and the process proceeds to step S15. In step S15, the display of the input position where the cursor 62 is located is changed in accordance with the newly input sound, and at the same time the corresponding sound is output from the ringer 22 and the RAM 49 is generated.
Change the sound data in. At the same time, the cursor 62 is moved to the next input position to wait for new input or correction input.

In step S14, the clear key 15
When is operated, the display of the input position where the cursor 62 is located is cleared, and the sound data in the RAM 49 is also erased. In step S16, it is determined whether or not a confirmation input for confirming the set ringing tone has been made. For example, when the memory call key 11 is operated, it is determined that a confirmation input has been made, and the process proceeds to step S17. In step S17, the ring tone that is currently being input is called from the work area of the RAM 49 and sounded through the ringer 22.

In step S18, it is determined whether or not there is an input to finish the setting input of the ring tone. Here, for example, when the memory key 12 is operated, it is determined that there is an input to finish the setting input of the ring tone, the process proceeds to step S19, and when it is determined that there is no such input, the process proceeds to step S12. . In step S19, RA
EEP the set ringtone stored in the work area of M49
It is stored in the ringtone storage area of the ROM 48.

The ring tone set by repeating steps S12 to S18 is set as tone data of the scale "Doremi Doremi" as shown in FIG. 8C, and stored in the EEPROM 48 in step S19. It will be. In step S20, it is determined whether a ringtone selection input has been made. For example, when "21" is input subsequently to the function key 16 ("F / small"), it is determined that the ring tone selection input has been made, and the process proceeds to step S21.

In step S21, the prepared ringing tones are "# 1", "# 2", "#" according to their types.
3 "or the like is displayed, and the set ringtone stored in step S19 is displayed as, for example,"# 4 ".
The system waits for the user's input and sets which ringtone is to be generated based on the input from the ten-key pad 14. Step S7
The incoming call processing will be described with reference to FIG.

In step S31, it is determined which ring tone is selected, and the EPROM 47 or EEPRO is selected.
The ringtone data stored in M48 is read. In step S32, the ringer 22 produces a sound based on the ringing tone read in step S31. Step S3
At 3, it is determined whether the start key 7 or the end key 8 has been operated. When it is determined that the start key 7 or the end key 8 is not operated, the process proceeds to step S34. In step S34, the variable k is incremented. This variable k counts the number of times the ringing tone is sounded based on the incoming call request signal. In step S35, the variable k and the constant n are compared. The constant n is a preset number, and when the number of times the ringtone is pronounced reaches this constant n,
It is set to activate the answering machine. In step S35, if the variable k is smaller than the constant n, the process proceeds to step S32, and if the variable k is equal to or larger than the constant n, the process proceeds to step S36.

In step S36, the other party is informed that the user is in a state where the user cannot talk, such as being away. After this, the process proceeds to step S39. If it is determined in step S33 that the start key 7 or the end key 8 has been operated, the process proceeds to step S37. In step S37, a process corresponding to the key operated in step S33 is performed. For example, if the start key 7 is operated in step S33, the normal call mode is started, and if the end key 8 is operated, the user is informed that the user cannot talk, and the call is made. Put on hold.

In step S38, it is determined whether or not a termination operation has been performed. Here, the process proceeds to step S37 until the end key 8 is operated, and when the end key 8 is operated, it is considered that the operation by the user is performed and the step S37 is performed.
Move to 39. In step S39, the communication is terminated and the variable k is reset. Other Embodiments (A) The display of the set sound in the ring tone setting mode is shown in FIG.
