Description

  The present invention relates to a telephone, a call control method, and a call control program.

  Conventionally, when a call is made using a telephone such as a mobile phone or a fixed phone, the user normally ends the call after agreeing with the call partner on the end of the call. However, even after an agreement has been reached with the other party, the user may want to continue the call in order to convey the message when he / she recalls another message.

  In such a case, the user calls the call partner to discourage the end of the call, but if the call partner has already removed his ear from the receiving speaker in order to disconnect the call, the call is sent to the call partner. In many cases, the call is disconnected without receiving. In such a case, the user has to make another call to the other party, which is troublesome.

  In order to avoid such a situation, for example, when a call disconnecting operation such as pressing the power key is performed by the user, the line is not disconnected immediately, and the line connection state is maintained for a certain period. There has been proposed a technique for outputting a voice uttered by a communication partner from a speaker.

  Hereinafter, embodiments of a telephone, a call control method, and a call control program disclosed in the present application will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  The telephone according to the present embodiment provides predetermined information when the user is away from the receiving speaker for the call disconnecting operation and it is difficult to notice the call continuation call from the other party. By informing the user, the user is made aware of the intention of the call partner to continue the call. FIG. 1 shows a configuration of a telephone according to the present embodiment. As shown in the figure, the telephone 500 according to the present embodiment includes a state determination unit 510, a voice recognition unit 520, a comparison unit 530, and a notification unit 540.

  The state determination unit 510 determines whether or not the user has removed his / her ear from the receiving speaker in a state where a telephone communication connection has been established with another telephone. A state in which a telephone communication connection is established with another telephone indicates a state in which a user of the telephone 500 and a user of the other telephone (calling partner) are talking.

  The voice recognition unit 520 recognizes the contents of a voice signal input from another telephone, that is, the utterance contents of the other party.

  When the state determination unit 510 determines that the user has removed his / her ear from the receiving speaker, the comparison unit 530 continues the call with the content of the other party's utterance recognized by the voice recognition unit 520. Compare the content with intention. Here, the “content indicating the intention to continue calling” is the content of the utterance that the other party calls to the user to continue the call after agreeing with the user on the end of the call. For example, “Hello” And "Wait a minute".

  As a result of the comparison by the comparison unit 530, the notification unit 540 notifies the user of predetermined information when the content of the other party's utterance matches a predetermined content indicating intention to continue the call.

  That is, the telephone 500 according to the present embodiment first uses the state determination unit 510 to make a state in which the user releases his / her ear from the reception speaker during a call, in other words, a call output from the reception speaker. It is determined whether or not it is difficult to notice the other party's calling voice. In addition, the telephone 500 monitors the utterance content of the other party by the voice recognition unit 520.

  Subsequently, when the state determination unit 510 determines that the user has removed his / her ear from the receiving speaker during a call, the telephone 500 determines in advance the content of the other party's utterance recognized by the voice recognition unit 520. The content indicating the intention to continue the call is compared using the comparison unit 530. Then, if the content of the other party's utterance matches the predetermined content indicating the intention to continue the call, that is, in the other party's utterance content, a call to the user such as "Hello" or "Wait a minute" When the call for continuation is included, the telephone set 500 notifies the user of predetermined information by the notification unit 540. For example, the notification unit 540 outputs an alarm sound from a notification speaker.

  As described above, in this embodiment, when the user is away from the receiving speaker during a call, if the call partner calls for continuation of the call, predetermined information is notified to the user. . As a result, the user can recognize his / her intention to continue the call even if he / she is away from the receiving speaker and it is difficult to hear the call continuation call from the other party. As a result, the call partner can continue the call without being disconnected by the user. In addition, in this embodiment, when the other party does not intend to continue the call, the line is disconnected normally by the call disconnecting operation of the user or the other party, so that no extra line usage fee is generated. .

  Next, a telephone, a call control method, and a call control program according to the second embodiment will be described. In the following description, a mobile terminal device is used as an example of a telephone. The portable terminal device includes a mobile phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant), a portable personal computer having a communication function, and the like. However, the telephone set disclosed in the present application is not limited to the portable terminal device, but may be a fixed telephone or the like.

  First, a call control method according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram for explaining the call control method according to the present embodiment. The call control method according to the present embodiment notifies predetermined information when the user is away from the receiving speaker during a call and it is difficult to notice the call from the call partner to continue the call. By doing so, the user is made aware of the intention of the call partner to continue the call.

  Specifically, as shown in FIG. 2, it is assumed that the user of the mobile terminal device 1 according to the present embodiment and the user (calling partner) of another mobile terminal device 2 are in a call. That is, it is assumed that a connection for telephone communication is established between the mobile terminal device 1 and another mobile terminal device 2.

  In such a state, the mobile terminal device 1 first detects a state in which the user removes his ear from the receiving speaker (A). Specifically, the mobile terminal device 1 determines whether or not the user has removed his / her ear from the receiving speaker based on the detection result of the contact sensor provided in the vicinity of the receiving speaker.

  Subsequently, when detecting a state in which the user removes his / her ear from the receiving speaker, the mobile terminal device 1 detects the content representing the intention to continue the call from the voices uttered by the call partner (B). Specifically, when the mobile terminal device 1 detects a state in which the user removes his / her ear from the receiving speaker, the mobile terminal device 1 starts a speech recognition process for a speech signal input from another mobile terminal device 2. Then, the mobile terminal device 1 compares the utterance content of the call partner recognized by the speech recognition process with the content representing the intention to continue the call stored in advance, and determines whether or not they match.

  Here, the “content indicating the intention to continue calling” is the content of the utterance that the other party calls to the user to continue the call after agreeing with the user on the end of the call. For example, “Hello” And "Wait a minute". The mobile terminal device 1 stores these contents in advance as verification data.

  Subsequently, the portable terminal device 1 outputs an alarm sound from the notification speaker when the content representing the intention to continue the call is detected from the voice uttered by the other party (C). As a result, the user can recognize that the call partner has called for continuation of the call even in a state where the ear is separated from the reception speaker for the call disconnection operation.

  As described above, according to the call control method according to the present embodiment, when the user releases his / her ear from the receiving speaker for the call disconnecting operation, the call partner notifies the user of the utterance indicating the intention to continue the call. By outputting an alarm sound from the speaker, it is possible to make the user recognize the intention of the call partner to continue the call.

  Furthermore, the portable terminal device 1 invalidates the call disconnection operation by the user when the content indicating the intention to continue the call is detected from the voice uttered by the call partner (D). That is, when it is detected that the other party has issued a content indicating the intention to continue calling, the mobile terminal device 1 performs a predetermined operation on the operation unit such as pressing the power key as a call disconnecting operation. Even so, the operation is invalidated and the telephone communication disconnection process is not performed. As a result, it is possible to more reliably prevent the user from disconnecting the call immediately before the end of the call without noticing the call partner's call to continue the call.

  Next, a specific configuration of the mobile terminal device 1 according to the present embodiment will be described. FIG. 3 is a block diagram illustrating the configuration of the mobile terminal device 1 according to the present embodiment. In the following, description will be made centering on portions closely related to the present embodiment. Other portions are the same as those of the conventional portable terminal device, and thus the description thereof will be omitted or simplified.

  As illustrated in FIG. 3, the mobile terminal device 1 includes a wireless unit 11, a microphone 12, a receiving speaker 13, a notification speaker 14, a contact sensor 15, an operation unit 16, a vibrator 17, an LCD (Liquid Crystal).

  The wireless unit 11 transmits and receives wireless signals such as audio signals via an antenna. The microphone 12 is a sound collection unit that collects a user's voice and the like during a call.

  The receiving speaker 13 outputs the other party's voice based on the voice signal received via the wireless unit 11. The notification speaker 14 outputs a ring tone when a call is received or an e-mail is received, and outputs various operation sounds, alarm sounds, and the like. In general, sound output from the reception speaker 13 cannot be recognized unless the ear is brought into contact with or close to the reception speaker 13. On the other hand, the ring tone and alarm sound output from the notification speaker 14 can be recognized even if they are separated from the mobile terminal device 1 to some extent.

  The contact sensor 15 is a detection sensor that continuously detects contact of the user with the reception speaker 13. Specifically, the contact sensor 15 detects a contact of the user with the reception speaker 13 by detecting a change in electrical characteristics generated in the sensor element when the user contacts the reception speaker. The contact sensor 15 continues to output a predetermined signal to a state determination unit 307 described later while detecting contact of the user with the reception speaker 13.

  In this embodiment, the contact sensor 15 is used. However, the present invention is not limited to this, and a pressure sensor, a temperature sensor, or the like may be used as a detection sensor. The pressure sensor detects contact of the user with the reception speaker 13 by a pressure change that occurs when the user contacts the reception speaker 13. The temperature sensor detects contact of the user with the reception speaker 13 based on a temperature change that occurs when the user contacts the reception speaker 13. Further, by using an infrared sensor, a distance measuring sensor, or the like as a detection sensor, it is possible to detect the approach of the user to the receiving speaker. The infrared sensor detects the approach of the user to the reception speaker 13 by irradiating infrared rays and detecting the reflected light. The distance measuring sensor emits ultrasonic waves, laser light, or the like, and calculates the distance between the user and the reception speaker 13 based on the time until the reflected light returns, thereby receiving the user's reception speaker. An approach to 13 is detected.

  The operation unit 16 receives various input operations from the user. The operation unit 16 includes, for example, a numeric keypad, operation keys, a rotation selector, a cursor, a cross key, a setting key, a completion key, a clear key, a power key, and the like. The vibrator 17 notifies the user by vibrating the mobile terminal device 1. The LCD 18 is a display unit that displays characters and images. Note that the display unit is not necessarily an LCD, and may be, for example, an organic EL display or an electronic paper display.

  The storage unit 20 stores data, programs, and the like necessary for executing various processes by the control unit 30. In particular, as closely related to the present embodiment, the storage unit 20 includes a collation data storage unit 201. The collation data storage unit 201 stores predetermined character data as content indicating the intention to continue the call. Specifically, the collation data storage unit 201 stores, as character data, the content of the utterance called to the user in order to continue the call after the other party has agreed with the user to end the call. For example, the collation data storage unit 201 stores character data such as “Hello”, “Wait a minute”, “Ah”, “A little bit”.

  The control unit 30 is a control unit that controls the mobile terminal device 1. In particular, as closely related to the present embodiment, the control unit 30 includes a radio control unit 301, a call control unit 302, a speaker control unit 303, an operation control unit 304, a vibrator control unit 305, and display control. Unit 306. Furthermore, the control unit 30 includes a state determination unit 307, a voice recognition unit 308, and a determination unit 309.

  The wireless control unit 301 controls transmission / reception of wireless signals in various communications such as telephone, electronic mail, and the Internet. In particular, the radio control unit 301 receives an audio signal from the other telephone via the antenna and the radio unit 11 in a state where a telephone communication connection is established with the other telephone (during a call). The voice signal acquired via the microphone 12 and the call control unit 302 is transmitted to another telephone set via the radio unit 11 and the antenna. In addition, the radio control unit 301 passes a voice signal received via the antenna and the radio unit 11 to the call control unit 302 and the voice recognition unit 308.

  The call control unit 302 performs control related to call connection such as establishment or disconnection of telephone communication with another telephone. In addition, the call control unit 302 delivers the user's voice signal acquired via the microphone 12 to the wireless control unit 301 during a call. In addition, the call control unit 302 passes the audio signal acquired from the wireless control unit 301 to the speaker control unit 303 during a call. In addition, the call control unit 302 executes a call disconnection process based on an instruction from the operation control unit 304. The call disconnect processing will be described later.

  The speaker control unit 303 controls sound output to the reception speaker 13 and the notification speaker 14. Specifically, the speaker control unit 303 causes the audio signal acquired from the call control unit 302 to be output from the reception speaker 13. In addition, the speaker control unit 303 causes the notification speaker 14 to output a predetermined alarm sound based on an instruction from the determination unit 309 described later.

  When the user performs an operation on the operation unit 16, the operation control unit 304 instructs the corresponding processing unit to execute a process corresponding to the operation. In particular, the operation control unit 304 instructs the call control unit 302 to execute a call disconnection process when a call disconnecting operation by the user is acquired from the operation unit 16. The call disconnecting operation by the user is, for example, pressing of a power key.

  Here, the operation control unit 304 according to the present embodiment shifts to a state in which the call disconnection degree operation by the user is invalidated in response to an instruction from the determination unit 309 described later. When the operation control unit 304 shifts to a call disconnection operation invalidation state, the operation control unit 304 executes the call disconnection process to the call control unit 302 even when the operation of the call disconnection degree by the user is acquired from the operation unit 16. Do not instruct.

  The vibrator control unit 305 controls the vibration of the vibrator 17. In particular, the vibrator control unit 305 vibrates the vibrator 17 in response to an instruction from a determination unit 309 described later.

  The display control unit 306 performs display control on the LCD 18. In particular, the display control unit 306 displays on the LCD 18 that the call partner has been called to continue the call in response to an instruction from the determination unit 309 described later.

  Based on the detection result of the contact sensor 15, the state determination unit 307 determines whether or not the user is away from the receiving speaker 13. Specifically, the state determination unit 307 determines that the user has not contacted the reception speaker 13 with the contact sensor 15, that is, has not acquired a predetermined signal from the contact sensor 15. Is in a state where the ear is separated from the receiving speaker 13. The state determination unit 307 inputs a predetermined signal to the determination unit 309 when it is determined that the user is in a state of releasing the ear from the reception speaker 13.

  The voice recognition unit 308 recognizes the utterance content of the other party on the basis of a voice signal input from another telephone. Specifically, the voice recognition unit 308 converts the voice signal acquired from the wireless control unit 301 into character data.

  Also, the voice recognition unit 308 compares the recognized utterance content of the other party with the content indicating the predetermined intention to continue the call. Specifically, voice recognition unit 308 compares whether or not the character data converted from the voice signal from another telephone matches the character data stored in collation data storage unit 201. For example, when the converted character data includes “Hello”, which is character data stored in the collation data storage unit 201, the speech recognition unit 308 continues the call content of the call partner and a predetermined call. It is determined that the content representing the intention matches. The voice recognition unit 308 determines a predetermined signal when it is determined that the utterance content of the other party of the call matches the predetermined content indicating the intention to continue the call, that is, when a call to continue the call by the other party is detected. Input to the unit 309.

  As described above, the voice recognition unit 308 functions as a voice recognition unit that recognizes the content of a voice signal input from another telephone, and also includes the content of the recognized voice signal and the content indicating a predetermined call continuation intention. It functions as a comparison unit that compares. In this embodiment, the voice recognition unit 308 starts or ends its operation according to an instruction from the determination unit 309 described later.

  The determination unit 309 instructs each processing unit based on an input signal from the state determination unit 307 or the voice recognition unit 308. Specifically, when the determination unit 309 acquires a signal from the state determination unit 307 that the user has detected that the user has removed his / her ear from the reception speaker 13, the determination unit 309 performs voice recognition processing on the voice recognition unit 308. Instruct the start.

  In addition, the determination unit 309 instructs the speaker control unit 303 to output a predetermined alarm sound from the notification speaker 14 when a signal indicating that a call continuation call by the other party has been detected is acquired from the voice recognition unit 308. . Further, the determination unit 309 instructs the vibrator control unit 305 to vibrate the vibrator 17 instead of the instruction to the speaker control unit 303 or together with the instruction to the speaker control unit 303 according to the setting state. Similarly, the determination unit 309 instructs the display control unit 306 to display on the LCD 18 that the call partner has been called to continue the call according to the setting status.

  As described above, the determination unit 309, the speaker control unit 303, and the reception speaker 13 correspond to an example of a notification unit that notifies the user of predetermined information. Similarly, the determination unit 309, the vibrator control unit 305, and the vibrator 17 correspond to an example of a notification unit. Similarly, the determination unit 309, the display control unit 306, and the LCD 18 correspond to an example of a notification unit.

  In addition, when the determination unit 309 obtains a signal indicating that a call continuation call by the other party has been detected from the voice recognition unit 308, the determination unit 309 instructs the operation control unit 304 to start an invalid state of the call disconnecting operation by the user. Instruct.

  Next, the operation of the mobile terminal device 1 according to the present embodiment will be described. First, the operation of the mobile terminal device 1 in the case where the user is prompted to continue the call based on the call voice from the other party will be described with reference to FIG. FIG. 4 is a sequence diagram for explaining the operation of the mobile terminal device in a case where the user is prompted to continue the call based on the call voice for continuing the call from the other party.

  As shown in FIG. 4, in a state in which a telephone communication connection is established between the mobile terminal device 1 and another mobile terminal device 2 (during a call), the user and the other party have agreed on the end of the call. Assume that the user removes his / her ear from the reception speaker 13 for the call disconnecting operation (step S01). In such a case, the mobile terminal device 1 detects a state in which the user removes his / her ear from the reception speaker 13, operates the voice recognition unit 308, and starts monitoring the calling voice for continuing the call from the other party (step). S02).

  Subsequently, it is assumed that the other party utters a call continuation voice such as “Moshimoshi” (step S03). In such a case, the other mobile terminal device 2 transmits the calling voice to the mobile terminal device 1 via the exchanges A and B. Then, when the call voice is acquired from another portable terminal device 2 during monitoring by the voice recognition unit 308, the portable terminal device 1 outputs a predetermined alarm voice from the notification speaker 14 (step S04).

  In addition, the mobile terminal device 1 starts an invalidation state of the call disconnecting operation (step S05). When the user performs a call disconnecting operation while the call disconnecting operation is invalidated (step S06), the mobile terminal device 1 invalidates the call disconnecting operation by the user (step S07). Thereby, the mobile terminal device 1 can maintain a call state with another mobile terminal device 2 even when the user accidentally presses the power key or the like.

  Subsequently, it is assumed that the user recognizes the other party's intention to continue the call using the alarm sound output from the notification speaker 14 and puts his ear on the receiving speaker 13 (step S08). As a result, the conversation between the user and the other party is resumed, so that the other party can tell the user another message or the like that was remembered immediately before the end of the call. When the user listens to the reception speaker 13, the mobile terminal device 1 stops the alarm sound (step S09), cancels the invalidation state of the call disconnection operation (step S10), and calls for continuing the call. Monitoring is terminated (step S11). As a result, the mobile terminal device 1 returns to the same state as before step S01, that is, the normal call state in which the call continuation call monitoring and the call disconnection operation are not invalidated.

  Next, the operation of the mobile terminal device 1 when the call is terminated without detecting a call continuation voice from the call partner will be described with reference to FIG. FIG. 5 is a sequence diagram for explaining the operation of the mobile terminal device 1 when the call is terminated without detecting a call continuation voice from the call partner. Note that steps S21 and S22 in FIG. 5 are the same as steps S01 and S02 in FIG.

  As shown in FIG. 5, it is assumed that the user performs a call disconnecting operation in a state where a call continuation call of the other party is being monitored (step S23). In such a case, the mobile terminal device 1 ends the monitoring of the call for continuation of the call (step S24), and starts the call disconnection process (step S25).

  When the call disconnection process is started, the mobile terminal device 1 transmits a call disconnect signal (DISCCONNECT signal: hereinafter referred to as “DISC signal”) to the exchange A to which the mobile terminal device 1 belongs. When the exchange A receives the DISC signal from the mobile terminal device 1, the exchange A transmits a release signal (RELEASE signal: hereinafter referred to as “REL signal”) to the mobile terminal device 1. Further, when the exchange A receives the DISC signal from the mobile terminal device 1, the exchange A transmits a REL signal to the exchange B to which the other mobile terminal device 2 belongs. When receiving the REL signal from the exchange A, the exchange B transmits a DISC signal to the other mobile terminal device 2. Then, when the other mobile terminal device 2 receives the DISC signal from the exchange B, it transmits a REL signal to the exchange B. Thereby, the telephone communication established between the mobile terminal device 1 and the other mobile terminal device 2 is disconnected.

  As described above, when the call disconnecting operation is performed by the user in the case where the call continuation call from the other party is not detected, the mobile terminal device 1 normally does not invalidate the operation. Execute call disconnect processing. In other words, when the other party does not intend to continue the call, the user can end the call by a normal call disconnection operation after agreeing with the other party on the end of the call.

  Subsequently, a processing procedure of the control unit 30 according to the present embodiment will be described. FIG. 6 is a flowchart illustrating the processing procedure of the control unit according to the present embodiment. In FIG. 6, only the processing procedure related to the call continuation intention notification process that causes the user who has removed his / her ear from the receiving speaker 13 to recognize the call continuation intention of the other party of the call is performed. Show.

  As illustrated in FIG. 6, when the call continuation intention notification process is started, first, the state determination unit 307 determines whether or not the user has removed his / her ear from the reception speaker 13 (step S101). Specifically, the state determination unit 307 determines whether or not the user has removed his / her ear from the reception speaker 13 depending on whether or not the contact of the user with the reception speaker 13 is detected by the contact sensor 15. Determine. In this processing, when it is determined that the user is in a state where the user has removed his / her ear from the reception speaker 13 (Yes at Step S101), the control unit 30 proceeds to Step S102.

  In step S102, the speech recognition unit 308 starts speech recognition processing based on the speech signal acquired from the wireless control unit 301. Specifically, the voice recognition unit 308 converts the voice signal acquired from the wireless control unit 301 into character data, and converts the converted character data and predetermined character data stored in the collation data storage unit 201. Compare.

  Subsequently, the voice recognition unit 308 determines whether a call continuation call voice from the call partner has been detected (step S103). Specifically, the voice recognition unit 308 determines whether or not the other party determines whether the character data converted from the voice signal from the wireless control unit 301 matches the predetermined character data stored in the collation data storage unit 201. It is determined whether or not a call continuation voice is detected. In such a process, when the calling voice from the other party is not detected (No at Step S103), the control unit 30 moves the process to Step S104.

  In step S104, the operation control unit 304 determines whether or not a call disconnecting operation by the user has been acquired. Specifically, the operation control unit 304 determines whether or not the call disconnecting operation by the user has been acquired based on whether or not the power key has been pressed by the user. In this process, when it is determined that the call disconnecting operation by the user has been acquired (Yes at Step S104), the voice recognition unit 308 ends the voice recognition process based on the voice signal acquired from the wireless control unit 301 (Step S105). . Further, the call control unit 302 starts executing the call disconnection process (step S106).

  On the other hand, when the call disconnection operation has not been acquired in step S104 (No in step S104), the state determination unit 307 determines whether or not the user is in a state of putting the ear on the reception speaker 13 (step S107). . Specifically, the state determination unit 307 determines whether or not the user has put the ear on the receiving speaker 13 depending on whether or not the contact sensor 15 has detected that the user has touched the receiving speaker 13. Determine. In such a process, when the user is not in a state of listening to the reception speaker 13 (No at Step S107), the control unit 30 proceeds to Step S103. On the other hand, when it is determined that the user is in a state where the ear is attached to the reception speaker 13 (Yes in step S107), the voice recognition unit 308 ends the voice recognition process based on the voice signal acquired from the wireless control unit 301 ( Step S108).

  When the process of step S108 is completed, or when the user is not in a state of taking the ear off the reception speaker 13 in step S101 (No in step S101), the control unit 30 shifts the process to step S101.

  On the other hand, when it is determined in step S103 that a call continuation call voice from the call partner has been detected (Yes in step S103), the speaker control unit 303 outputs an alarm sound from the notification speaker 14 (step S109). In addition, the operation control unit 304 starts an invalid state of the call disconnecting operation (step S110).

  Subsequently, the state determination unit 307 determines whether or not the user is in a state where the user listens to the reception speaker 13 (step S111). In such a process, when the user is not in a state of listening to the receiving speaker 13 (No at Step S111), the operation control unit 304 determines whether or not the call disconnecting operation by the user has been acquired (Step S112). .

  In this process, when it is determined that the call disconnecting operation by the user has been acquired (Yes at Step S112), the operation control unit 304 invalidates the acquired call disconnecting operation (Step S113). That is, if the voice recognition unit 308 detects a call continuation call voice from the other party in step S103, the operation control unit 304 may obtain a call disconnecting operation by the user from the operation unit 16. The call control unit 302 is not instructed to execute the call disconnection process. When the process of step S113 is completed, or when the call disconnecting operation by the user is not acquired in step S112 (No in step S112), the control unit 30 moves the process to step S111.

  On the other hand, when it is determined in step S111 that the user is in a state where the user listens to the reception speaker 13 (Yes in step S111), the speaker control unit 303 stops outputting the alarm sound from the notification speaker 14 (step S111). S114). Further, the operation control unit 304 cancels the invalidation state of the call disconnection operation (step S115). In addition, the voice recognition unit 308 ends the voice recognition process based on the voice signal from the wireless control unit 301 (step S116).

  When the process of step S116 is completed or when the process of step S106 is completed, the control unit 30 ends the processing procedure related to the call continuation intention notification process.

  Next, the operation of each processing unit will be described more specifically. First, the operation of each processing unit when prompting the user to continue a call based on a call continuation voice from the other party will be described. FIG. 7 is a sequence diagram for explaining the operation of each processing unit in a case where the user is prompted to continue the call based on the call voice from the call partner to continue the call.

  As illustrated in FIG. 7, when the state determination unit 307 determines that the user has removed his / her ear from the reception speaker 13 based on the detection result of the contact sensor 15 during a call (step S201), A signal indicating that the ear is separated from the reception speaker 13 is transmitted to the determination unit 309. When the determination unit 309 acquires the signal from the state determination unit 307, the determination unit 309 instructs the voice recognition unit 308 to start the operation (step S202).

  When the start of the operation is instructed from the determination unit 309, the speech recognition unit 308 starts speech recognition processing based on the speech signal from the wireless control unit 301 (step S203). Then, it is assumed that the voice recognizing unit 308 detects a call continuation voice from the other party (step S204). That is, it is assumed that the character data generated by converting the wireless signal from the wireless control unit 301 matches the predetermined character data stored in the verification data storage unit 201. In such a case, the voice recognition unit 308 transmits a signal indicating that the call continuation calling voice has been detected to the determination unit 309 (step S205).

  Subsequently, when a signal indicating that a call continuation calling voice has been detected is acquired from the voice recognition unit 308, the determination unit 309 instructs the speaker control unit 303 to output an alarm sound (step S206). Accordingly, the speaker control unit 303 that has received the instruction causes the alarm speaker 14 to output an alarm sound.

  In addition, the determination unit 309 instructs the operation control unit 304 to start a call disconnection operation invalidation state (step S207). As a result, the operation control unit 304 that has received the instruction starts an invalidation state of the call disconnection operation (step S208).

  Subsequently, when the state determination unit 307 determines that the user is in a state where the ear is attached to the reception speaker 13 (step S209), the state determination unit 307 determines a signal indicating that the user is in the state where the ear is attached to the reception speaker 13. To the unit 309. When the determination unit 309 acquires the signal from the state determination unit 307, the determination unit 309 instructs the speaker control unit 303 to stop the alarm sound (step S210). Accordingly, the speaker control unit 303 that has received the instruction stops outputting the alarm sound from the notification speaker 14.

  In addition, the determination unit 309 instructs the operation control unit 304 to cancel the invalidation state of the call disconnection operation (step S211). Thereby, the operation control unit 304 cancels the invalidation state of the call disconnection operation (step S212).

  Further, the determination unit 309 instructs the voice recognition unit 308 to end the operation (step S213). When the end of the operation is instructed from the determination unit 309, the voice recognition unit 308 ends the voice recognition process based on the voice signal from the wireless control unit 301 (step S214).

  Next, the operation of each processing unit when a call is terminated without detecting a call continuation voice from a call partner will be described. FIG. 8 is a sequence diagram for explaining the operation of each processing unit when the call is terminated without detecting a call continuation voice from the call partner. Note that the processing in steps S301 to S303 in FIG. 8 is the same as the processing in steps S201 to S203 in FIG.

  As shown in FIG. 8, it is assumed that the operation control unit 304 acquires a call disconnecting operation by the user in a state where the voice recognition unit 308 is operating (step S304). In such a case, the operation control unit 304 transmits a signal indicating that the call disconnecting operation has been performed to the determination unit 309. Then, the determination unit 309 that has acquired the signal instructs the voice recognition unit 308 to end the operation (step S305). When the end of the operation is instructed from the determination unit 309, the voice recognition unit 308 ends the voice recognition process based on the voice signal from the wireless control unit 301 (step S306).

  Next, the operation of each processing unit when the user listens to the receiving speaker without detecting the call continuation voice from the call partner will be described. FIG. 9 is a sequence diagram for explaining the operation of each processing unit when the user listens to the receiving speaker without detecting the call continuation voice from the call partner. Note that the processing in steps S401 to S403 in FIG. 9 is the same as the processing in steps S201 to S203 in FIG.

  As illustrated in FIG. 9, it is assumed that the state determination unit 309 determines that the user is in a state of wearing the earpiece on the reception speaker 13 in a state where the voice recognition unit 308 is operating (step S404). In such a case, the state determination unit 309 transmits a signal to the determination unit 309 that the user is in a state where the user listens to the reception speaker 13. Then, the determination unit 309 that has acquired the signal instructs the voice recognition unit 308 to end the operation (step S405). When the end of the operation is instructed from the determination unit 309, the voice recognition unit 308 ends the voice recognition process based on the voice signal from the wireless control unit 301 (step S406).

  As described above, in this embodiment, when the user releases his / her ear from the receiving speaker 13 for the call disconnecting operation and the utterance indicating the intention to continue the call is made from the other party, the alarm speaker 14 gives an alarm. By outputting the sound, the user is made aware of the intention of the call partner to continue the call. Thereby, the other party can continue the call without being disconnected by the user. In addition, in this embodiment, when the other party does not intend to continue the call, the line is disconnected normally by the call disconnecting operation of the user or the other party, so that no extra line usage fee is generated. .

  Also, in this embodiment, after the user releases his / her ear from the receiving speaker 13 for the call disconnecting operation, the call disconnecting operation by the user is invalidated when an utterance indicating the intention to continue the call is made from the other party. To do. As a result, it is possible to more reliably prevent the user from disconnecting the call immediately before the end of the call without noticing the call partner's call to continue the call.

  In the above-described second embodiment, in order to make the user recognize the call just before the end of the call from the call partner, after the user removes his ear from the receiving speaker 13 for the call disconnect operation, the call partner intends to continue the call. When an utterance indicating is made, an alarm sound is output.

  By the way, when a calling state continues from a certain telephone to another telephone for a long time, the user may determine that the other party is absent and perform a call disconnecting operation. In such a case, when the user removes his / her ear from the receiving speaker for the call disconnecting operation, even when the other party answers the call from the user, the answer from the other party is not received. There is a case where the call is disconnected without noticing that there was.

  Therefore, in this embodiment, after the state determination unit 307 detects a state in which the user removes his / her ear from the receiving speaker 13, when a telephone communication connection is established, an alarm sound is output from the notification speaker 14. The user is made aware that the other party has answered the call.

  First, a call control method according to the present embodiment (hereinafter referred to as “call response notification method”) will be described with reference to FIG. FIG. 10 is a diagram for explaining the call response notification method according to the present embodiment.

  As shown in FIG. 10, the mobile terminal device 1 ′ according to the present embodiment is still in a call state to another mobile terminal device 2, that is, a telephone communication connection is established with the other mobile terminal device 2. Suppose you are not in a state. In such a state, the mobile terminal device 1 ′ first detects a state in which the user removes his / her ear from the receiving speaker using the contact sensor 15 and the state determination unit 307 (A).

  Subsequently, when the user detects a state in which his / her ear is removed from the reception speaker 13, it is assumed that the other party responds to a call from the mobile terminal device 1 ′ and a telephone communication connection is established. In such a case, the mobile terminal device 1 ′ detects that a telephone communication connection has been established with another mobile terminal device 2. That is, the mobile terminal device 1 ′ detects a line connection with another mobile terminal device 2 (B).

  When detecting a line connection with another mobile terminal device 2, the mobile terminal device 1 'outputs an alarm sound from the notification speaker (C).

  As described above, according to the call response notification method according to the present embodiment, the alarm sound is output from the notification speaker when the connection of the telephone communication is established after the user removes the ear from the reception speaker for the call disconnection operation. , It is possible to make the user recognize that there is a response to the telephone call from the other party.

  Further, as in the second embodiment, the mobile terminal device 1 ′ disables the call disconnecting operation by the user when the connection of the telephone communication is established when the user detects the state where the user removes his / her ear from the receiving speaker 13. (D). That is, even when the user performs a predetermined operation on the operation unit 16 such as pressing the power key as a call disconnection operation, the mobile terminal device 1 ′ invalidates the operation and performs a call disconnection process. Absent. As a result, it is possible to more reliably prevent a situation where the user disconnects the call despite a response from the call partner.

  Next, the configuration of the mobile terminal device 1 ′ according to the present embodiment will be described. FIG. 11 is a block diagram of the configuration of the mobile terminal device according to the third embodiment. In addition, the same code | symbol is attached | subjected about the same thing as the already demonstrated structure, and the description is abbreviate | omitted.

  In the mobile terminal device 1 ′ according to the present embodiment, the wireless control unit 301 ′ determines whether or not a telephone communication connection has been established with another telephone in addition to the functions described in the second embodiment. Functions as a connection state determination unit. When the radio control unit 301 ′ determines that a telephone communication connection has been established with another telephone, the radio control unit 301 ′ transmits a predetermined signal to the determination unit 309 ′.

  When the state determination unit 307 determines that the user has removed his / her ear from the reception speaker 13, the determination unit 309 ′ notifies an alarm sound when a predetermined signal is acquired from the wireless control unit 301 ′. The speaker control unit 303 is instructed to output from the speaker 14. Accordingly, the speaker control unit 303 that has received the instruction outputs an alarm sound from the notification speaker 14. As described above, the determination unit 309 ′, the speaker control unit 303, and the notification speaker 14 correspond to an example of a notification unit.

  Next, operation | movement of portable terminal device 1 'concerning a present Example is demonstrated. First, a case where there is no response from the call partner and the user ends the call will be described. FIG. 12 is a sequence diagram for explaining a case where the user ends the call without a response from the other party.

  As shown in FIG. 12, it is assumed that the user performs an outgoing call operation to another mobile terminal device 2 (step S31). In such a case, the mobile terminal device 1 ′ transmits a call setting signal (SETUP signal) to the exchange A. Upon receiving the SETUP signal from the mobile terminal device 1 ′, the exchange A transmits a call setup acceptance signal (CALL PROCEDING signal: hereinafter referred to as “CALLPROC signal”) to the mobile terminal device 1 ′ as a response. . Further, when the exchange A receives the SETUP signal from the mobile terminal device 1 ′, the exchange A transmits an INITIAL ADDRESS MESSAGE signal (hereinafter referred to as “IAM signal”) to the exchange B.

  When the exchange B receives the IAM signal from the exchange A, it transmits a SETUP signal to the other mobile terminal device 2. When the other portable terminal device 2 receives the SETUP signal from the exchange B, as the calling operation, for example, it rings a ring tone or vibrates the vibrator. Further, when the other mobile terminal device 2 receives the SETUP signal from the exchange B, it transmits a calling signal (ALERTING signal: hereinafter referred to as “ALERT signal”) to the exchange B.

  When the exchange B receives the ALERT signal from the other mobile terminal device 2, the exchange B transmits an ADDRESS COMPLETE MESSAGE signal (hereinafter referred to as “ACM signal”) to the exchange A. When the exchange A receives the ACM signal from the exchange B, the exchange A transmits an ALERT signal to the mobile terminal device 1 ′. When receiving the ALERT signal from the exchange A, the portable terminal device 1 ′ outputs, for example, a ringing tone (ringback tone) from the reception speaker 13 as a calling operation. Thereby, portable terminal device 1 'will be in the calling state with respect to the other portable terminal device 2. FIG.

  Subsequently, for example, when the calling state continues for a long time, it is assumed that the user determines that the other party is absent and releases his / her ear from the receiving speaker 13 for the call disconnecting operation (step S32). In such a case, the mobile terminal device 1 ′ starts a line connection establishment waiting state (step S33). Specifically, the mobile terminal device 1 ′ starts a process of determining whether or not a connection for telephone communication with another mobile terminal device 2 has been established by the wireless control unit 301 ′.

  Subsequently, it is assumed that the user disconnects the call without connecting the line (step S34). In such a case, the mobile terminal device 1 ′ ends the line connection establishment waiting state (step S35), and starts executing the call disconnection process (step S36).

  Specifically, when the mobile terminal device 1 ′ starts the call disconnection process, the mobile terminal device 1 ′ transmits a DISC signal to the exchange A to which the mobile device 1 ′ belongs. When the exchange A receives the DISC signal from the mobile terminal device 1 ′, the exchange A transmits a REL signal to the mobile terminal device 1 ′. Further, when the exchange A receives the DISC signal from the mobile terminal device 1 ′, the exchange A transmits a REL signal to the exchange B to which the other mobile terminal device 2 belongs. When receiving the REL signal from the exchange A, the exchange B transmits a DISC signal to the other mobile terminal device 2. Then, when the other mobile terminal device 2 receives the DISC signal from the exchange B, it transmits a REL signal to the exchange B. Thereby, the call with respect to the portable terminal device 2 of portable terminal device 1 'is complete | finished.

  As described above, when the mobile terminal device 1 ′ is in a call of the other mobile terminal device 2 and the line connection with the other mobile terminal device 2 is established, the call disconnecting operation is performed by the user. The call disconnection process is executed as usual.

  Next, the operation of the mobile terminal device 1 ′ when notifying the user that there has been a response from the other party based on the establishment of the line connection will be described. FIG. 13 is a sequence diagram for explaining the operation of the mobile terminal device when notifying the user that there has been a response from the calling party based on the establishment of the line connection. Note that the processing in steps S41 to S43 in FIG. 13 is the same as the processing in steps S31 to S33 in FIG.

  As shown in FIG. 13, it is assumed that the call partner performs an on-hook operation to respond to a call from the mobile terminal device 1 ′ while the mobile terminal device 1 ′ is waiting for establishment of a line connection (step S44). In such a case, the other portable terminal device 2 transmits a CONNECT signal to the exchange B. When the exchange B receives the CONNECT signal from the other mobile terminal device 2, the exchange B transmits an ANSWER MESSAGE signal (hereinafter referred to as an ANM signal) to the exchange A. When the ANM signal is received from the exchange B, the exchange A transmits a CONNECT signal to the mobile terminal device 1 ′. Thereby, the line between the mobile terminal device 1 ′ and the other mobile terminal device 2 is connected, that is, the connection of the telephone communication between the mobile terminal device 1 ′ and the other mobile terminal device 2 is established.

  In a state where the user removes his / her ear from the reception speaker 13, when a line with another mobile terminal device 2 is connected, the mobile terminal device 1 ′ outputs an alarm sound from the notification speaker 14 (step S45). Further, the mobile terminal device 1 ′ starts an invalid state of the call disconnecting operation (step S46). When the user performs a call disconnecting operation while the call disconnecting operation is invalidated (step S47), the mobile terminal device 1 ′ disables the call disconnecting operation (step S48). That is, the mobile terminal device 1 ′ does not execute the call disconnection process even when the call disconnection operation is acquired from the user in the call disconnection operation invalid state.

  On the other hand, it is assumed that the user notices that the other party has responded to the call by the alarm sound output in step S45 and listens to the reception speaker 13 (step S49). Thereby, the conversation between the user and the other party is started. When the user listens to the reception speaker 13, the portable terminal device 1 ′ stops the alarm sound (step S50), cancels the invalidation state of the call disconnection operation (step S51), and waits for establishment of a line connection. The state is terminated (step S52).

  Next, the processing procedure of the control unit 30 ′ according to the present embodiment will be described. FIG. 14 is a flowchart illustrating the processing procedure of the control unit 30 ′ according to the present embodiment. In FIG. 14, in the processing procedure executed by the control unit 30 ′, when the other mobile terminal device 2 is in a calling state, the other party of the user who is away from the receiving speaker 13 is called the other party. Only the processing procedure relating to the call response notification process for recognizing that the call has been answered is shown.

  As shown in FIG. 14, when the call response notification process is started, first, the state determination unit 307 determines whether or not the user has removed his / her ear from the reception speaker 13 (step S501). Specifically, the state determination unit 307 determines whether or not the user has removed his / her ear from the reception speaker 13 depending on whether or not the contact of the user with the reception speaker 13 is detected by the contact sensor 15. Determine. In this process, when it is determined that the user has removed his / her ear from the reception speaker 13 (Yes at Step S501), the control unit 30 ′ moves the process to Step S502.

  In step S502, the radio control unit 301 ′ starts a line connection establishment waiting state. Subsequently, the radio control unit 301 ′ determines whether or not a line connection has been established, that is, whether or not a telephone communication connection has been established with another mobile terminal device 2 (step S503). In such a process, when a telephone communication connection is not established with another mobile terminal device 2 (No at Step S503), that is, when the other mobile terminal device 2 is still in a calling state, the control unit 30 ′ Shifts the processing to step S504.

  In step S504, the operation control unit 304 determines whether or not a call disconnecting operation by the user has been acquired. Specifically, the operation control unit 304 determines whether or not the call disconnecting operation by the user has been acquired based on whether or not the power key has been pressed by the user. In this process, when it is determined that the call disconnecting operation by the user has been acquired (Yes at Step S504), the radio control unit 301 ′ ends the line connection waiting state (Step S505). In addition, the call control unit 302 starts executing the call disconnection process (step S506).

  On the other hand, if the call disconnection operation has not been acquired in step S504 (No in step S504), the state determination unit 307 determines whether or not the user is in a state where the user has listened to the reception speaker 13 (step S507). . Specifically, the state determination unit 307 determines whether or not the user has put the ear on the receiving speaker 13 depending on whether or not the contact sensor 15 has detected that the user has touched the receiving speaker 13. Determine. In this process, if the user is not in a state of listening to the receiving speaker 13 in step S507 (No in step S507), the control unit 30 moves the process to step S503. On the other hand, when it is determined that the user is in a state where the user has listened to the receiving speaker 13 (Yes at Step S507), the voice recognition unit 308 ends the line connection waiting state (Step S508).

  When the process of step S508 is completed, or when the user is not in a state of releasing the ear from the reception speaker 13 in step S501 (No in step S501), the control unit 30 ′ shifts the process to step S501.

  On the other hand, when it determines with line connection having been established in step S503 (step S503 affirmation), the speaker control part 303 outputs an alarm sound from the notification speaker 14 (step S509). In addition, the operation control unit 304 starts an invalid state of the call disconnecting operation (step S510).

  Subsequently, the state determination unit 307 determines whether or not the user is in a state of putting the ear on the reception speaker 13 (step S511). In such a process, when the user is not in a state of listening to the receiving speaker 13 (No at Step S511), the operation control unit 304 determines whether or not the call disconnecting operation by the user has been acquired (Step S512). .

  In this process, when it is determined that the call disconnecting operation by the user has been acquired (Yes at Step S512), the operation control unit 304 invalidates the acquired call disconnecting operation (Step S513). In other words, when it is detected in step S503 that the line is connected, the operation control unit 304 calls execution of the telephone communication disconnection process even when the call disconnecting operation by the user is acquired from the operation unit 16. The controller 302 is not instructed. When the process of step S513 is completed, or when the call disconnecting operation by the user is not acquired in step S512 (No in step S512), the control unit 30 ′ shifts the process to step S511.

  On the other hand, when it is determined in step S511 that the user is in a state where the user has listened to the reception speaker 13 (Yes in step S511), the speaker control unit 303 stops outputting the alarm sound from the notification speaker 14 (step S511). S514). Further, the operation control unit 304 cancels the invalidation state of the call disconnection operation (step S515). Further, the radio control unit 301 ′ ends the line connection establishment waiting state (step S516).

  When the process of step S516 is completed or when the process of step S506 is completed, the control unit 30 ′ ends the processing procedure related to the call response notification process.

  Next, the operation of each processing unit will be described more specifically. The operation of each processing unit when notifying the user that there has been a response from the other party based on the establishment of the line connection will be described. FIG. 15 is a sequence diagram for explaining the operation of each processing unit when notifying the user that there has been a response from the other party based on establishment of the line connection.

  As shown in FIG. 15, when the state determination unit 307 first determines that the user has removed his / her ear from the reception speaker 13 based on the detection result of the contact sensor 15 (step S601), the user receives the call. A signal indicating that the ear is away from the speaker 13 is transmitted to the determination unit 309 ′. When the determination unit 309 ′ acquires the signal from the state determination unit 307, the determination unit 309 ′ instructs the wireless control unit 301 ′ to start a line connection establishment waiting state (step S602).

  When the determination unit 309 ′ instructs the start of a line connection establishment waiting state, the radio control unit 301 ′ starts the line connection establishment wait state (step S603). Then, it is assumed that the radio control unit 301 ′ detects establishment of a line connection (step S604). Specifically, when the radio control unit 301 ′ receives a CONNECT signal from the exchange A, the radio control unit 301 ′ detects the CONNECT signal, thereby performing telephone communication between the mobile terminal device 1 ′ and another mobile terminal device 2. It is determined that a connection has been established. In such a case, the radio control unit 301 ′ transmits a signal indicating that the establishment of the line connection has been detected to the determination unit 309 ′ (step S605).

  Subsequently, when a signal indicating that the establishment of the line connection has been detected is acquired from the wireless control unit 301 ′, the determination unit 309 ′ instructs the speaker control unit 303 to output an alarm sound (step S606). Accordingly, the speaker control unit 303 that has received the instruction causes the alarm speaker 14 to output an alarm sound.

  Also, the determination unit 309 ′ instructs the operation control unit 304 to start a call disconnection operation invalidation state (step S607). As a result, the operation control unit 304 that has received the instruction starts an invalidation state of the call disconnection operation (step S608).

  Subsequently, when the state determination unit 307 determines that the user is in a state where the ear is attached to the reception speaker 13 (step S609), the state determination unit 307 determines a signal that the user is in a state where the ear is attached to the reception speaker 13. To the unit 309 ′. When the determination unit 309 ′ acquires the signal from the state determination unit 307, the determination unit 309 ′ instructs the speaker control unit 303 to stop the alarm sound (step S610). Accordingly, the speaker control unit 303 that has received the instruction stops outputting the alarm sound from the notification speaker 14.

  Further, the determination unit 309 ′ instructs the operation control unit 304 to cancel the invalidation state of the call disconnection operation (step S611). Thereby, the operation control unit 304 cancels the invalidation state of the call disconnection operation (step S612).

  In addition, the determination unit 309 ′ instructs the radio control unit 301 ′ to end the line connection establishment waiting state (step S613). If the determination unit 309 ′ instructs the end of the line connection establishment waiting state, the radio control unit 301 ′ ends the line connection establishment waiting state (step S614).

  As described above, in this embodiment, when a call is established to another mobile terminal device 2 and the user establishes a connection for telephone communication after releasing the ear from the receiving speaker for the call disconnection operation. By outputting an alarm sound from the notification speaker, the user can recognize that there has been a response to the telephone call from the other party.

  Further, the mobile terminal device 1 ′ is used when a telephone communication connection is established after the user removes his / her ear from the receiving speaker for a call disconnection operation during a call to another mobile terminal device 2. The call disconnection action by the user is disabled. As a result, it is possible to more reliably prevent a situation where the user disconnects the call despite a response from the call partner.

  By the way, the function equivalent to the portable terminal device 1 can also be realized by implementing the function of the portable terminal device 1 in the second embodiment as software and executing the software on the telephone. Below, an example of the telephone which performs the telephone call control program which mounted the function of the portable terminal device 1 as software is shown. FIG. 16 is a block diagram illustrating a telephone that executes a call control program.

  As shown in FIG. 16, the telephone 600 includes a wireless unit 601, a microphone 602, a receiving speaker 603, a notification speaker 604, a contact sensor 605, an operation unit 606, a vibrator 607, and an LCD 608. These correspond to the wireless unit 11, the microphone 12, the reception speaker 13, the notification speaker 14, the contact sensor 15, the operation unit 16, the vibrator 17, and the LCD 18 shown in FIG. The telephone 600 includes a central processing unit (CPU) 610 that executes various arithmetic processes, a non-volatile memory 620 that stores various information, and a random access memory (RAM) 630. In addition, the telephone 600 connects them to each other via a bus 640.

  The nonvolatile memory 620 stores a call control program that exhibits the same function as in the present embodiment, that is, a state determination program 621, a voice recognition program 622, a comparison program 623, and a notification program 624.

  Then, the CPU 610 reads the state determination program 621, the voice recognition program 622, the comparison program 623, and the notification program 624 from the nonvolatile memory 620 and expands them in the RAM 630, so that each of the programs 621 to 624 includes the state determination process 631 and the voice, respectively. It functions as a recognition process 632, a comparison process 633, and a notification process 634. Thus, the CPU 610 corresponds to the control unit 30 shown in FIG.

  In addition, the nonvolatile memory 620 includes a verification data storage unit 625. The CPU 610 reads out information stored in the collation data storage unit 625 and stores it in the RAM 630, and the processes 631 to 634 execute various processes using the data stored in the RAM 630.

  Similarly to the above, by implementing the function of the mobile terminal device 1 ′ in the third embodiment as software and executing the software on the telephone, it is possible to realize a function equivalent to the mobile terminal device 1 ′.

  As described above, some of the embodiments of the present invention have been described in detail with reference to the drawings. However, these are merely examples, and various embodiments can be made based on the knowledge of those skilled in the art including the aspects described in the section of the disclosure of the invention. The present invention can be implemented in other forms that have been modified or improved.

  For example, in the second embodiment, it is determined whether or not the call partner is calling to continue the call by comparing the utterance content of the call partner with a predetermined utterance content stored in the verification data storage unit 201. But it is not limited to this. For example, the voice recognizing unit 308 may determine that a call to continue the call from the call partner has been made when a certain utterance from the call partner is recognized. Specifically, when the voice signal input from another telephone is converted into character data, the voice recognition unit 308 determines that a call to continue the call from the other party is detected, and determines a predetermined signal. 309.

  In the second embodiment, the presence / absence of the call partner's intention to continue the call is determined based on the utterance of the call partner. However, the present invention is not limited to this. For example, when the mobile terminal device 1 is in a call with another telephone and is notified from the other telephone that a predetermined operation to the operation unit has been performed by the other party, the mobile terminal device 1 intends to continue the call. You may judge that there is. Thereby, for example, when the other party recalls another message immediately before the end of the call, the user can indicate the intention to continue the call to the user by long pressing a predetermined key.

  In the second embodiment and the third embodiment, the operation control unit 304 maintains the call disconnection operation invalidated state until the determination units 309 and 309 ′ instruct to cancel the call disconnection operation invalidated state. However, it is not limited to this. For example, the operation control unit 304 may cancel the invalidation state of the call disconnection operation when a predetermined time has elapsed after the call disconnection operation is started. In such a case, the duration of the call disconnection operation invalidation state may be arbitrarily changed by setting.

  Further, in the third embodiment, the mobile terminal device 1 ′ detects the state in which the user releases his / her ear from the reception speaker 13 by the state determination unit 307 during a call to another mobile terminal device 2, and then performs telephone communication. When the connection is established, the call disconnecting operation by the user is invalidated. However, when the other mobile terminal device 2 is equipped with a so-called answering machine function, the other mobile terminal device 2 automatically responds to a call from the mobile terminal device 1 ′, and the other mobile terminal device 1 ′ and the others. In some cases, a line is connected to the mobile terminal device 2. In such a case, the portable terminal device 1 ′ outputs an alarm sound from the notification speaker 14, so that the user who wants to leave a message for the other party has the answering function of the other portable terminal device 2. It can be recognized that it is operating.

  On the other hand, the user may think that it is not necessary to leave a message for the other party. In such a case, since the call disconnecting operation is invalidated even if the user tries to end the call, the line connection state may be maintained unnecessarily. In order to avoid such a situation, for example, the voice recognition unit 308 can be used.

  Specifically, when a signal indicating that the establishment of the line connection is detected is acquired in step S605 in FIG. 15, the determination unit 309 ′ instructs the voice recognition unit 308 to start the operation. Subsequently, the voice recognizing unit 308 recognizes the contents of the voice signal input from the other portable terminal device 2 to determine whether or not the contents of the voice signal are messages that flow during the operation of the voice recording function. judge. When the voice recognition unit 308 determines that the content of the voice signal input from the other mobile terminal device 2 is a message that flows during the operation of the answering machine function, the determination unit 309 ′ disables the call disconnection operation. The operation control unit 304 is instructed to release the activated state. As a result, it is possible to avoid a situation where the user cannot disconnect even if he / she wants to disconnect the line. In such a case, the collation data storage unit 201 stores character data corresponding to a message that flows when the answering machine function operates.

  Also, when a telephone communication connection is established with another mobile terminal device 2, whether the other party responds to the call, or whether the other mobile terminal device 2 responds automatically by the answering machine function It may be determined whether or not a call disconnection operation invalidation state is to be started. Specifically, for example, information that identifies whether the CONNECT signal transmitted from the other portable terminal device 2 to the exchange B is responded by the on-hook operation of the other party or by the answering function is included. Make it. When the wireless control unit 301 ′ obtains a CONNECT signal from the switching center A, the wireless control unit 301 ′ refers to the information to determine whether the response is due to the call partner's on-hook operation or the answering function. To do. If it is determined that the response is due to the answering function, the determination unit 309 ′ does not instruct the operation control unit 304 to start the invalidation state of the call disconnection operation. This also avoids a situation where the user cannot disconnect the line even if he wants to disconnect it.
