Description

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 user who can suitably respond to a call when the user does not want to receive a response when receiving a call.

[0002]

2. Description of the Related Art The ultimate goal of a telephone is to be able to make a phone call "anytime, anywhere, with anyone". To meet this goal, the development of the telephone has been promoted. The spread of mobile phones using the is remarkable. Due to the small size, light weight, and simplicity of mobile phones, users are always carrying around with them, and they enjoy making calls "anytime, anywhere, with anyone."

FIG. 2 is a block diagram showing a configuration of a conventional mobile phone capable of achieving such an ultimate goal.

In FIG. 2, an antenna 1 commonly used for transmission and reception includes a transmission filter (for example, bandpass filter) 2 and a reception filter (for example, bandpass filter).
Connected to 3. The transmission filter 2 is for the transmission signal frequency band, the reception filter 3 is for the reception signal frequency band, and is for preventing frequency collision due to sharing the antenna 1.

The weak reception signal whose band is limited by the reception filter 3 is amplified by the reception amplifier 4 and given to the mixer section 5. The mixer unit 5 includes a receiver-side VCO.
An oscillation signal having a frequency corresponding to a predetermined channel to be received is also given from the (voltage controlled oscillator) 7, and thus the reception signal of the channel to be received is taken out from the mixer section 5. The radio section microprocessor 8 controls the crystal oscillator 6 and the receiver-side VCO 7,
The original oscillation signal is supplied to the receiving side VCO 7, and the receiving side VCO performs frequency conversion or phase control to form an oscillation signal to be supplied to the mixer section 5. The reception signal of the predetermined channel output from the mixer unit 5 is
The signal is supplied to an IF (intermediate frequency processing) block 9, the frequency is reduced and converted into a baseband signal, and the modem unit 11
And to the reception baseband circuit 13. A digital signal or a voice signal obtained by modulating communication control data is transmitted to such a mobile phone, and the main microprocessor 12 determines the transmission mode from the signal from the modem unit 11, for example, and the modem unit according to the determination result. 11 and the reception baseband circuit 13 and the like.

If the baseband signal is a digital signal obtained by modulating communication control data, the modem section 11 demodulates it and is taken in as information by the main microprocessor 12. The main microprocessor 12 performs processing according to this data and displays the received data in the display unit 2.
Display it on 3. For example, if it is call data for the mobile phone, an incoming call process is performed (a ringer (not shown) is rung).

On the other hand, the baseband signal which is an audio signal is corrected by the receiving baseband circuit 13 in terms of frequency characteristics and the like, and then amplified by the reception amplifier 14 and given to the speaker 15. It is electroacoustic converted and transmitted to the human ear.

On the other hand, the voice uttered by the human mouth is captured by the microphone 16, acoustic-electrically converted, further amplified by the preamplifier 17, and then given to the transmission baseband circuit 18. The transmission baseband circuit 18 corrects the frequency characteristic of the transmission voice signal and gives it to the synthesis section 19. On the other hand, in the data transmission mode, the communication control data output from the main microprocessor 12 is modulated by the modem unit 11 and then given to the combining unit 19.

In this way, the transmission voice signal or the digital signal (data modulation signal) is sent from the synthesizing section 19 to the VCO 2 on the transmitting side.
It is output to 0. The transmitter VCO 20 forms an oscillation signal whose center is a radio frequency corresponding to a predetermined channel designated by the control of the radio microprocessor 8, and whose frequency is shifted by the signal voltage from the synthesizer 19 ( A voice signal or a digital signal is modulated) and is supplied to the transmission power amplifier 21. The power amplifier 21 amplifies a signal to a predetermined power under the control of the radio section microprocessor 8, and the transmission signal thus amplified is given to the antenna 1 through the transmission filter 2 and radiated as a radio wave into the air.

The main microprocessor 12 includes an operation section 22 in which a dial section and other function keys are housed,
A display unit 23 is provided in association with the main microprocessor 12, and the main microprocessor 12 controls the entire mobile phone according to the operation contents on the operation unit 22 and necessary contents according to the processing stage (such as dialed number and The electric field strength of the radio wave, the in-range, out-of-range information, etc.) are displayed on the display unit 23.

With the above-mentioned configuration, the calling process, the incoming process and the subsequent voice signal transfer process are performed.

Due to the portability of the mobile phone, as described above, the mobile phone can respond to a call from the other party regardless of the location, time, etc. However, sometimes, there are situations in which it is unfavorable or unfavorable for social life to make a phone call because of the location. For example, if you are eating at a quiet restaurant, at a concert venue, or during an important meeting, you should refrain from using the telephone in situations where it may bother others. Of course, the call origination is not a problem because the user of the mobile phone may refrain from doing so, but the call origination problem is serious because the user cannot control it.

In the past, a user of a mobile phone has forcibly avoided an incoming call at a place or case where an incoming call is not desirable, by turning off the power of the telephone.

[0014]

However, if the power supply of the mobile telephone is cut off, the call cannot be answered naturally, and even if the call can be accepted, forget to turn on the power. There is a risk that important contacts will be lost, which is not satisfactory for users. Therefore, a mobile phone having a so-called silent incoming call display (silent call) function has already been proposed. The silent incoming call display function is the backlight for night illumination of the dial keys and the display provided on the mobile phone when the user receives an incoming call while selecting this mode with the operation keys. Is a function to call the user's attention by blinking the character indicating that there is an incoming call on the display, and preventing a person other than the user from feeling uncomfortable with a ringing sound, In addition, the user is required to know the incoming call, change the place, etc. and request a response.

However, even if the user notices the silent incoming call display, it is naturally not possible to respond depending on the situation.
Further, in many cases, the user is distracted by other business (e.g., eating or playing in the above example) and does not notice the silent incoming call display. Therefore, it is hard to say that the silent incoming call display function is effectively functioning for the user.

On the other hand, when the user cannot respond to the incoming call, the user does not respond to the incoming call regardless of whether or not the silent incoming call display function is provided. Regardless, I feel frustrated at not responding. Also, some callers repeat the call many times and cannot get in touch at all, further exacerbating frustration. Such a repeated call is not a preferable situation because many invalid calls are generated from the viewpoint of the telephone system.

The present invention has been made in consideration of the above points, and it is possible to secure the method of contacting the caller even when the user cannot answer the incoming call, and the caller is useless. It is an object of the present invention to provide an excellent mobile phone that can reduce the number of invalid calls even if the telephone system does not repeat such outgoing calls.

[0018]

In order to solve such a problem, in the mobile phone of the present invention, a response hold for holding a response from a user to an incoming call and setting and resetting a response hold mode for automatically responding The mode setting release means, the voice response means including a semiconductor storage medium that stores the message transmitted by the automatic response and outputs the message voice signal when instructed, and the response hold mode is set. When there is a call, an automatic response control means for automatically receiving an incoming call, outputting a message voice signal from the voice response means and responding to the caller is provided.

Here, the DTMF signal for receiving and analyzing the DTMF signal output when the caller pushes the push button is received.
It is preferable to further include a receiving unit and a received number display unit for displaying the number received by the DTMF receiving unit on the display unit.

Further, it is preferable that a voice recording means for recording the voice uttered by the user and captured by the microphone is provided, and the voice response means outputs the message voice signal recorded by the voice recording means.

[0021]

In the portable telephone of the present invention, when the answer hold mode setting canceling means holds the response by the user to the incoming call, and the answer hold mode for automatically answering is set, the incoming call is automatically sent. The response control means automatically receives the call and causes the caller to output the stored message voice signal from the voice response means. As a result, the caller can obtain information that the user of the mobile phone cannot answer or other information, and it is not necessary to worry about the incoming call during the period when the user cannot answer the call. The system can be expected to reduce the number of invalid calls.

Even when there is an incoming call in the response hold mode, the DTMF signal output when the caller pushes the push button is received so that the user can know the caller's telephone number and the like. It is preferable to further include DTMF receiving means for analysis and reception number display means for displaying the number received by the DTMF receiving means on the display unit.

Further, in order to increase the degree of freedom of the message given to the sender, a voice recording means for recording the voice uttered by the user and captured by the microphone is provided, and the voice response means records the message recorded by this voice recording means. It is preferable to output an audio signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) First Embodiment Hereinafter, a first embodiment of a mobile phone according to the present invention will be described in detail with reference to the drawings. Here, FIG. 1 shows a main part configuration of the first embodiment, and the same or corresponding parts as in FIG. 2 are designated by the same reference numerals. Further, FIG. 3 shows an example of storing in the message memory, FIG. 4 shows a setting process of the response hold mode in the first embodiment, FIG. 5 shows an incoming call process in the response hold mode, and FIG. 6 is a response hold mode. Shows the reset process of. Note that FIG. 5 is shown only in relation to the response hold mode.

In FIG. 1, in addition to the conventional structure shown in FIG. 2, the first embodiment is a voice response circuit for outputting a response hold message for an incoming call in a state where the response hold mode is set by voice. 24, and a synthesizing unit 35 for placing the response hold message voice on the transmission line. Further, the operation unit 22 of the first embodiment has various keys for setting and resetting the response hold mode and selecting an output message (even if existing keys are properly used in this way). Good) is provided,
The main microprocessor 12 is provided with various processing routines (FIGS. 4 to 6) relating to the response suspension mode, various fixed data, a buffer, and the like.

The voice response circuit 24 includes the message memory 2
5, a timing control circuit 28, a multiplexer 29, a voice synthesizing circuit 30, a digital / analog converter 31, a low-pass filter 33 and a voice amplifier 34, which can be integrated into one chip according to recent LSI technology. is there.

The message memory 25 is used for the sound source data section 2
6 and an address data section 27 that defines the data area thereof, and outputs the sound source data corresponding to the address to the multiplexer 29 when the address is given from the timing control circuit 28. Here, the sound source data is, for example, an ADPCM (adaptive difference PC)
M) is compression encoded.

FIG. 3 shows an example of storing sound source data. One message data is divided into a plurality of addresses and stored as a set of a plurality of sound source data.
Moreover, a plurality of message data are stored. In the case of the first embodiment, the message memory 25 storing the sound source data in this way is composed of a ROM.

The timing control circuit 28 controls the reading of the sound source data from the message memory 25 when the processing is started by the main microprocessor 12, and also controls the operation timing of the speech synthesis circuit 30 which will be described later. is there. The sound source data read from the message memory 25 under the control of the timing control circuit 28 is connected to one or more sentences (response hold message) by the multiplexer 29 to be combined with the voice synthesis circuit 30.
Given to.

Under the control of the timing control circuit 28, the voice synthesizing circuit 30 synthesizes the inputted message data to form a voice signal (digital signal) and supplies it to the digital / analog converter 31. If the above-mentioned sound source data is ADPCM-encoded data, the speech synthesis circuit 30 corresponds to an ADPCM decoding circuit.

The digital audio signal is converted into an analog signal by the digital / analog converter 31, then high frequency noise is removed through the low pass filter 33 to be smoothed, and further amplified by the audio amplifier 34. It is given to the synthesizing unit 35 as an output of the voice response circuit 24 and inserted into the transmission line.

The voice response circuit 24 having the above-mentioned configuration and performing the above-described operation operates under the control of the main microprocessor 12 when the response hold mode is set and an incoming call is received. To do.

The processing relating to the response holding mode performed by the main microprocessor 12 will be described below in the order of the response holding mode setting processing, the incoming call processing in the response holding mode, and the response holding mode reset processing. At this time, the operation of the user of the mobile phone will be made clear.

The user of the portable telephone operates the set key in the response hold mode provided in the operation unit 22 when or before the situation where the incoming call cannot be answered. When the main microprocessor 12 is given from the operation unit 22 that the set key in the response hold mode is operated,
The response holding mode setting processing routine shown in FIG. 4 is started, and first, one message data consisting of a character character code (for example, katakana and numbers) is taken out from the built-in fixed data section and the data expanded into pixels is displayed on the display section. 23 and display it (step 100). The main microprocessor 12 internally stores a character character code relating to a message having the same content as the message stored in the message memory 25. Then, after confirming that the end of message selection has not been instructed (step 101), the main microprocessor 12 determines whether or not the key for selecting the display message has been operated, and the selection key has not been operated. In that case, it is further determined whether or not the display message switching key has been operated (steps 102 and 103). When the display message switching key is operated, the process returns to step 100 and another message corresponding to the operation is displayed on the display unit 23.

When the user wants to send the displayed message to the other party at the time of an incoming call, the user operates the select key. At this time, the main microprocessor 12 causes the sound source data corresponding to the displayed message to be displayed. The transmission message information consisting of the start address and end address of the message memory 26 in which is stored is stored in the built-in transmission message buffer (step 104). afterwards,
The main microprocessor 12 proceeds to a determination step 103 for determining whether or not the display message switching key has been operated.

When the user finishes selecting all the messages he / she wants to send to the other party by the automatic response at the time of an incoming call, by operating the display message switching key and the selection key,
Operate the selection end key. As a result, the main microprocessor 12 obtains a positive result in step 101. Therefore, at the time of receiving a call, after the call processing routine in the response hold mode shown in FIG. 5 is executed or the display is erased. , The number of incoming calls parameter N is set to an initial value 0, and a series of setting processing is completed (steps 105, 10).
6).

As described above, when the control data provided from the modem section 11 (see FIG. 2) indicates an incoming call in the state where the response hold mode is set, the main microprocessor 12 normally operates. 5, the incoming call processing routine in the response hold mode shown in FIG. 5 is started.

First, the main microprocessor 1
2 performs automatic incoming call processing, then transfers the transmission message information (all sets of start address and end address in the message memory 25) stored in the transmission message buffer to the timing control circuit 28, and then the timing The control circuit 28 is activated to start the message transmission process, and then the incoming call number parameter N is incremented to display the number on the display unit 23 (step 1
20-124). As a result, the voice response circuit 24 outputs the voice signal of the message selected by the user and transmits it to the other party.

After that, the processing for disconnecting is performed and the processing at the time of the incoming call is ended (step 125). For example, waiting for the other party to disconnect, or the timing control circuit 28
It monitors the elapsed time from the time it is started and automatically disconnects when it reaches a predetermined time.

When the user returns to the state of being able to answer the incoming call, he operates the reset key in the answer hold mode. At this time, the main microprocessor 12 starts the reset processing routine in the response hold mode shown in FIG. First, the contents of the built-in transmission message buffer and the number N of incoming calls are cleared, and then the normal incoming call processing routine is switched so as to be activated at the time of an incoming call, and a series of processing is terminated (steps 130 and 131). ).

Next, an example of a method of using the response hold mode described above will be described. For example, when a user participates in a conference that does not respond to an incoming call, a response hold mode is set in advance, and at that time, a message to be automatically answered is selected. For example, if you know the end time of the meeting,
Select the message "I can't answer the phone right now""3o'clock""Please call me". In this state, the user enters the conference without turning off the power of the telephone. When there is an incoming call during the conference, the ring tone does not sound under the control of the main microprocessor 12, and an automatic incoming call is made and the message data from the message memory 25 "I cannot answer the phone right now""3o'clock""Callme" Please output ”, is converted into a voice signal and is transmitted to the other party. By selecting the response hold mode in this way, the minimum information can be given to the other party if there is an incoming call even during the conference.

Therefore, according to the above-described first embodiment, even when the user cannot answer the incoming call, it is possible to give the caller no answer or the time information for which the redial is valid. From the point of view, you can feel secure that you will be able to get in touch with them later, and from the perspective of the caller, there is no need to repeat useless call operations and the other party cannot respond because there is an automatic response. You can feel relieved by knowing that the phone function is enhanced. There is also an advantage that the number of invalid calls can be reduced from the viewpoint of the telephone communication system.

Further, the user can recognize the presence or absence of an incoming call based on the number of incoming calls, and in this respect also the user's sense of security can be enhanced.

Here, as the recording medium for the response message, a tape-shaped or disk-shaped recording medium is conceivable. However, in this case, since a mechanism is required, it is practical because of the size limitation of the portable telephone. is not.

Further, in the car telephone system, in consideration of safe driving, when the user operates the car telephone and selects the response hold mode, the switching system side automatically gives a message indicating that the caller cannot respond. Although there is one that is returned as a response, in this case, the content of the response is a fixed type, and various responses cannot be made. In this car telephone system, the user cannot confirm the existence of an incoming call that was within the response hold period.

As a modification of the first embodiment, a message to be executed without displaying the message contents on the display unit 23 at the time of selecting a transmission message, or a voice response circuit 24 at the time of selecting a transmission message is used. An example is one that is operated so that a voice signal is generated from the receiving speaker 15 to confirm the message content. Further, the time when the call is received may be recorded and displayed. Furthermore, it is also possible to omit the number of incoming calls in the response hold mode. Furthermore, it is also possible to always send a fixed message voice in the response hold mode without having a message selection function.

(B) Second Embodiment Next, a second embodiment of the mobile phone according to the present invention will be described in detail with reference to the drawings. Here, FIG. 7 shows a main part configuration of the second embodiment, and the same or corresponding parts as in FIG. 1 are designated by the same reference numerals. 8 shows the response holding mode setting process in the second embodiment, FIG. 9 shows the incoming call process in the response holding mode, and FIG. 10 shows the response holding mode reset process.

In the second embodiment, as is apparent from the comparison between FIGS. 1 and 7, the DTMF (dual ton) present in the baseband signal output from the reception baseband circuit 13 is present.
e multiple frequency) A DTMF receiver 36 for receiving and analyzing a signal is provided, and the D detected by the DTMF receiver 36
Instruction content of the TMF signal (also called PB signal) (1,
2, 3, 4, 5, 6, 7, 8, 9, 0, etc.) is provided to the main microprocessor 12 in terms of hardware from the first embodiment.

Hereinafter, the processing relating to the response holding mode performed by the main microprocessor 12 of the second embodiment will be described in the order of the response holding mode setting processing, the call receiving processing in the response holding mode, and the response holding mode reset processing. To do.
At this time, the operation of the user of the mobile phone will be made clear.

The user of the portable telephone of this embodiment also operates the set key in the response hold mode when or before the situation in which the incoming call cannot be answered. When the main microprocessor 12 is given from the operation unit 22 that the set key in the response holding mode is operated, the response holding mode shown in FIG. 8 which is the same as that in FIG. The set processing routine of is started. In the case of the second embodiment, the display message data is provided with a flag indicating whether or not the message is a message for requesting the other party's telephone number.

The set processing routine of the second embodiment started as described above differs from the set processing routine of the first embodiment in processing when a display message is selected.
That is, when the display message is selected, it is determined whether or not the selected message is a message for requesting the telephone number of the other party (step 107). If you get a negative result,
After storing the transmission message information including the start address and the end address of the message memory 26 in which the sound source data corresponding to the selected message is stored in the built-in transmission message buffer (step 104), the display message switching determination step 103 is performed. move on. On the other hand, if an affirmative result is obtained, it means that the send message information consisting of the start address and end address is stored in the built-in send message buffer, and the other party's telephone number is obtained.
Set the TMF signal reception flag (step 108),
Furthermore, after setting the partner number storage area parameter P to the initial value (step 109), the process proceeds to the display message switching determination step 103. Other processes are the same as those in the first embodiment.

As described above, when the control data provided from the modem section 11 (see FIG. 2) represents an incoming call in the state where the response hold mode is set, the main microprocessor 12 normally operates. The incoming call processing routine in the response hold mode shown in FIG. 9 in which the same reference numerals as those in FIG.

In this second embodiment, as is clear from the comparison between FIGS. 5 and 9, the step 124 of displaying the number of incoming calls is shown.
And the cutting processing step 125, the following processing steps are provided.

That is, based on the DTMF signal reception flag, it is judged whether or not the transmitted message includes a message for requesting the telephone number of the other party (step 12).
6). If not included, disconnect immediately Step 12
If it is included, the numerical information (destination telephone number) from the DTMF receiver 36 is fetched and stored in the area designated by the destination number storage area parameter P, and the number is called. It is displayed on the display unit 23 in parallel with the number of times, and after the partner number storage area parameter P is further incremented by 1, the process proceeds to the disconnection step 125 (steps 127 and 128).

In this way, the other party number of the latest incoming call and the number of incoming calls are displayed, and the telephone numbers of all the other incoming calls during the response hold mode period are stored.

When the user returns to the state of being able to respond to the incoming call, he operates the reset key in the response hold mode. At this time, the main microprocessor 12 starts the reset processing routine of the response hold mode shown in FIG. 10 in which the same steps as those in FIG. Then, first, the contents of the built-in transmission message buffer and the parameter of the number of incoming calls are cleared (however, the number of incoming calls is continuously displayed), and then it is determined whether or not there is a received telephone number of the other party (steps 130 and 132). If not, the process immediately proceeds to step 131 described later. On the other hand, if there is, it is determined whether or not the change key of the displayed partner number has been operated (step 133). If operated, the other party's number storage area parameter P is decremented by 1 to display the other party's telephone number in the area on the display unit 23 (step 134). If not operated, is the display clear key further operated? It is determined whether or not (step 135). When the display clear key is operated, the display is cleared and the partner number storage area parameter P
After clearing (step 136), a normal incoming call processing routine is switched so as to be activated at the time of incoming call, and a series of processing is ended (step 131). When the display clear key is not operated, the processing returns to step 132. .

Therefore, according to the second embodiment, the same effect as that of the first embodiment can be obtained, and the user can know the caller's telephone number and can return to the state of being able to respond. After that, it is possible to surely contact the caller, and it is also possible to obtain the effect that the caller does not have to be strongly aware of another call.

As a modified example of the second embodiment, the same modified example as the first embodiment can be mentioned. Further, the DTMF signal may be used for purposes other than fetching the other party's telephone number. For example, the caller may give the expected outgoing time to the user as a DTMF signal to the mobile phone and display it. Further, a message requesting the telephone number of the other party may be transmitted at all times.

(B) Third Embodiment Next, a second embodiment of the mobile phone according to the present invention will be described in detail with reference to the drawings. Here, FIG. 11 shows the configuration of the main part of the third embodiment, and the same or corresponding parts as in FIG. 7 are designated by the same reference numerals. Further, FIG. 12 shows a setting process in the response hold mode in the third embodiment.

The third embodiment differs from the second embodiment in terms of hardware in the detailed configuration of the voice response circuit 24, as is apparent from the comparison between FIGS. 7 and 11.

That is, the voice recording circuit 38 is provided in the voice response circuit 24. The voice recording circuit 38 is composed of an analog / digital converter 39, a voice analysis circuit 40, a buffer circuit 41 and a second message memory 42, and the respective units 39 to 42 are controlled by the timing control circuit 28. It is done like this.

The microphone 16 captures the preamplifier 1
The voice signal, which is amplified by 7 and becomes a message to the caller, is converted into a digital signal by the analog / digital converter 39 and is given to the voice analysis circuit 40.
The voice analysis circuit 40 analyzes the input digital voice signal, compresses and encodes it, and the buffer circuit 41 subjects the coded signal to address space processing for storage in the memory 42. It is stored in the message memory 42.

The speech analysis circuit 40 performs the reverse processing of the speech synthesis circuit 30, and when the speech synthesis circuit 30 is composed of, for example, an ADPCM decoding circuit, the speech analysis circuit 30 is an ADPCM coding circuit. Is applicable.

The above-mentioned second message memory 42 is also connected to the multiplexer 29, and when the timing control circuit 28 instructs the reading, the stored sound source data is output to the multiplexer 29. There is.

Here, it is conceivable that the voice recording circuit 38 is constructed by using a tape-shaped or disk-shaped recording medium, but if this is done, a mechanism portion is required, and therefore the size of the mobile phone is restricted. From not practical.

Incidentally, even the voice response circuit 24 having the voice recording circuit 38 can be realized by a small number of IC chips due to the recent development of LSI technology, and can be easily mounted on a mobile phone.

By providing such a voice recording circuit 38, when the call is received in the response hold mode, not the message stored in the message memory 26 built into the telephone but the user's arbitrary message is transmitted to the caller. can do.

Hereinafter, the processing relating to the response holding mode performed by the main microprocessor 12 of the third embodiment will be described in the order of the response holding mode setting processing, the incoming call processing in the response holding mode, and the response holding mode reset processing. To do.

The user of the mobile phone of this embodiment also operates the set key in the response hold mode when or immediately before the situation where the call cannot be answered. When the main microprocessor 12 is given that the set key in the response hold mode is operated from the operation unit 22, the same as in FIG.
Corresponding steps are designated by the same reference numerals, and the response hold mode set processing routine shown in FIG. 12 is started. In addition,
In the case of the second embodiment, the display message data includes
A flag indicating whether or not the message is a message requesting the other party's telephone number is added.

In the set processing routine of the third embodiment started as described above, first, based on the operation key information from the operation section 22, whether the user has instructed to select the message built in the telephone set or not. It is determined whether the user has instructed to select an arbitrary message to be uttered (step 110).

Here, when an instruction to select a message built in the telephone is instructed, the same processing as the set processing routine (steps 100 to 109) of the second embodiment is performed.

On the other hand, when an instruction to select an arbitrary message is given, the user is instructed to sound through the display section 23 and the timing control circuit 28 is instructed to perform a voice recording process (step 111). . After that, the fact that an arbitrary message has been selected as the message to be output at the time of an incoming call is stored in the transmission message buffer and the DTMF signal reception flag indicating that the other party's telephone number is requested is set (step 111), and the other party's number storage area is set. After setting the parameter P to the initial value (step 112),
Go to step 105. As described above, when the arbitrary message is transmitted, the receiving function of the DTMF signal is automatically enabled.

When the voice recording process is instructed, the timing control circuit 28 controls the voice recording circuit 38 to store the sound source data related to the voice signal uttered by the user in the second message memory 42.

As described above, when the control data provided from the modem section 11 (see FIG. 2) represents an incoming call in the state where the response hold mode is set, the main microprocessor 12 normally operates. The incoming call processing routine in the response hold mode is started instead of the incoming call processing routine.

The incoming call processing routine in the response hold mode of the third embodiment is almost the same as the incoming call processing routine in the response hold mode of the second embodiment, and its illustration is omitted. The different point is that the transmission message information given to the timing control circuit 28 in step 121 (see FIG. 9) indicates an arbitrary message when the arbitrary message is selected in the above-mentioned set processing, and is included in the telephone. When a message is selected, it is the set information of the start address and end address of the message memory 26.

After the transmission message information indicating the arbitrary message is given, the timing control circuit 28 which is activated to transmit the sound source data relating to the arbitrary message from the second message memory 42 in the voice recording circuit 38. Output and send an arbitrary message voice signal to the caller.

When the user returns to the state of being able to answer the incoming call, the user operates the reset key in the answer hold mode. At this time, the main microprocessor 12 starts the reset processing routine in the response hold mode.

The reset processing routine in the response holding mode of the third embodiment is almost the same as the reset processing routine in the response holding mode of the second embodiment, and its illustration and description are omitted.

Therefore, according to the third embodiment, the same effect as the third embodiment can be obtained, and the user can give an arbitrary message to the sender.
It is also possible to obtain the effect that a more detailed automatic response can be performed.

In the case of the first and second embodiments, it is impossible to inform the caller of the situation in which only the prepared message can be answered. However, for example, a user of a mobile phone uses the Shinkansen from Osaka to Tokyo. Even if you can't answer the phone in the car while moving to, let's record the message "I am moving to Osaka by Shinkansen now. When I arrive in Osaka, I will call you back, so please send your phone number with a push button" It is possible to make detailed automatic responses.

As a modified example of the third embodiment, there may be mentioned one in which the transmission structure of the built-in message is omitted and only the arbitrary message is transmitted. In addition, the process of capturing the arbitrary message voice may be a process separated from the process of setting the response hold mode. further,
An example is one in which the voice recording circuit 38 is connected to the receiving line and the timing control circuit 28 is instructed to record at a predetermined timing to record the voice of the caller.

(D) Other Embodiments In the above embodiments, the stored sound source data is A
Although the DPCM coded one is shown, it may be one based on another coding method, or may be simply PCM processed.

Further, the portable telephone which is the object of the present invention is
The present invention is not limited to mobile phones using the cellular car phone system.

Further, a dial pulse receiver may be provided in addition to the DTMF receiver.

As described above, according to the present invention, the response holding mode setting canceling means for holding the response from the user to the incoming call and setting and resetting the response holding mode for automatically responding, and the automatic response. When a call is received in a state where the response hold mode is set, a voice response means including a semiconductor storage medium that stores the message transmitted by Equipped with automatic response control means that receives a call and outputs a message voice signal from the voice response means to respond to the caller, ensuring a method of contacting the caller even if the user cannot answer the call. Moreover, it is possible to reduce the number of invalid calls as a telephone communication system without the caller repeating unnecessary calls.
