Description

  The present invention relates to a portable communication device and an incoming call control method.

  Some portable information devices have a response limiting function for rejecting incoming calls from sources other than those registered in advance. Such a response limiting function is very useful from the viewpoint of security protection, but it sometimes causes inconvenience. For example, when an emergency call is made to an emergency contact such as the police, there may be a call back from the police, but if the response limit function is enabled, the telephone number of the police, etc. will accept the incoming call Incoming calls will be rejected unless they are on the phone number list.

  Therefore, a technology has been proposed for a mobile information device having a response limiting function, which can receive incoming calls from any source by relaxing the response limit for a certain period of time when an emergency call is made to the police, etc. (For example, patent document 1). By using such a technique, even a portable information device having a response limiting function can receive an incoming call from the police after an emergency call for a certain period of time.

  Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following description. In addition, constituent elements in the following description include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range. In the following, a mobile phone will be described as an example of a mobile communication device, but the application target of the present invention is not limited to a mobile phone. For example, a PHS (Personal Handyphone System), a mobile information processing apparatus with a call function, etc. The present invention can also be applied to.

(Embodiment 1)
First, a schematic configuration of functions of the mobile communication device 10 will be described. FIG. 1 is a block diagram illustrating a schematic configuration of functions of the mobile communication device 10. The mobile communication device 10 is a mobile phone having a wireless communication function. As shown in FIG. 1, the mobile communication device 10 includes a control unit 22, a storage unit 24, a communication unit 26, an operation unit 28, a voice processing unit 30, a display unit 32, and a call recording unit 34. Have.

  The control unit 22 is a processing unit that centrally controls the overall operation of the mobile communication device 10, for example, a CPU (Central Processing Unit). That is, the communication unit 26, the display unit, and the like so that various processes of the mobile communication device 10 are executed in an appropriate procedure according to the operation of the operation unit 28 and the software stored in the storage unit 24 of the mobile communication device 10. 32 and the like are controlled. The control unit 22 executes processing based on a program (for example, an operating system program, application program, etc.) stored in the storage unit 24. The control unit 22 can execute a plurality of programs (applications, software) in parallel.

  As part of the control of the operation of the mobile communication device 10, the control unit 22 responds to the response restriction mode in which the mobile communication device 10 responds only to incoming calls from a previously permitted source, and to incoming calls from any source. Switch to one of the response limit relaxation modes that respond. For example, if the user makes an emergency call from the mobile communication device 10 to an emergency contact such as the police while the mobile communication device 10 is switched to the response restriction mode, the mobile communication device 10 is put into the response restriction relaxation mode for a certain period of time. Switch. By controlling in this way, the mobile communication device 10 can receive a return phone call from the police or the like.

  When an emergency call is made to the police or the like, a return phone call may be received not only from the destination but also from the police station in charge. In order to be able to respond to such an incoming call, the mobile communication device 10 is switched to the response restriction relaxation mode capable of responding to an incoming call from an arbitrary source, instead of simply enabling an incoming call from the destination. There is a need.

  In addition, when the mobile communication device 10 is switched to the response restriction relaxation mode, when the mobile communication device 10 receives an incoming call from a source other than that permitted in advance, the control unit 22 sends the incoming call to another communication device registered in advance. However, we will shift to a three-party call that allows listening and speaking. In this way, by enabling the listening and speaking of the contents of the call to other than the user of the mobile communication device 10, the mobile communication device 10 can be switched to the response restriction relaxation mode and can respond to an incoming call from any source. It is possible to suppress a decrease in security caused by doing so.

  The memory | storage part 24 is a memory | storage device which memorize | stores various information, for example, memorize | stores information in semiconductors, such as flash memory. The storage unit 24 stores application programs and data used for processing in the control unit 22. Specifically, an application program for sending and receiving mail, an application program for reproducing audio data, an application program for performing outgoing, incoming call, and call processing are stored as application programs. As data, image data, audio data, dictionary data for character conversion, address book data, and the like are stored.

  In addition, the storage unit 24 stores an outgoing / incoming permission list 24a, an emergency destination list 24b, a three-party call number 24c, and an emergency call history 24d as data.

  The outgoing / incoming call permission list 24a is data in which telephone numbers that are allowed to be received and sent when the mobile communication device 10 is switched to the response restriction mode are registered. An example of the outgoing / incoming permission list 24a is shown in FIG. In the outgoing / incoming call permission list 24a shown in FIG. 2, four telephone numbers are registered, and for each telephone number, a "mother", so that the owner of the communication device corresponding to the telephone number can be easily identified. The names “Father”, “Home”, and “School” are associated with each other.

  The emergency call destination list 24b is data in which telephone numbers of police, fire fighting organizations, and the like, which are contacts when an emergency occurs, are registered. Even in the response restriction mode, the mobile communication device 10 makes a call to a telephone number registered in the emergency call destination list 24b according to a user operation. Then, when a call is made to a telephone number registered in the emergency destination list 24b during the response restriction mode, the control unit 22 switches the mobile communication device 10 to the response restriction relaxation mode for a certain period of time.

  An example of the emergency destination list 24b is shown in FIG. In the emergency call destination list 24b shown in FIG. 3, three telephone numbers are registered, and each telephone number has “Police”, “Fire” so that the call destination corresponding to the telephone number can be easily identified. , The name “security company” is associated.

  The three-party call origination number 24c is used when there is an incoming call from a third party not registered in the outgoing / incoming permission list 24a when the mobile communication device 10 is switched to the response restriction relaxation mode. Is a data in which a telephone number to be transmitted in order to shift to a three-party call is registered. For example, when the user of the mobile communication device 10 is a child, the phone number of the parent mobile phone device or the telephone number of the home landline phone device is registered in the calling number 24c for three-party calls, so that the child During the call of a third party, the child's family can listen to and speak the content of the call.

  An example of the three-party call origination number 24c is shown in FIG. In the three-party call origination number 24c shown in FIG. 4, one telephone number is registered, and the name “house” is assigned to the telephone number so that the destination corresponding to the telephone number can be easily identified. It is associated.

  The emergency call history 24d is data in which information related to outgoing calls is recorded in time series every time a call to a telephone number registered in the emergency call destination list 24b is made from the mobile communication device 10. An example of the emergency call history 24d is shown in FIG. The emergency call history 24d shown in FIG. 5 indicates that there were two calls to the telephone numbers registered in the emergency call destination list 24b, and each call was registered in the emergency call destination list 24b. The name and telephone number of the call destination, the call date and time, and the call end date and time are recorded.

  The outgoing / incoming permission list 24a, the emergency call destination list 24b, the three-party call number 24c, and the emergency call history 24d may be created and updated by the user operating the mobile communication device 10. However, it may be possible to create and update by operating other communication devices owned by the contractor of the mobile communication device 10. For example, when the user of the mobile communication device 10 is a child, a parent who is a contractor of the mobile communication device 10 operates their mobile communication device associated with the mobile communication device 10 in advance. This data may be created and updated.

  Referring to FIG. 1 again, the communication unit 26 has an antenna 26a, establishes a radio signal line by a CDMA method or the like with the base station via a channel assigned by the base station, and communicates with the base station. Perform telephone and information communications. The operation unit 28 includes various keys. When these keys are input by a user operation, a signal corresponding to the operation content is generated. The generated signal is input to the control unit 22 as a user instruction.

  The audio processing unit 30 executes processing of an audio signal input to the microphone 15 and an audio signal output from the receiver 16. The display unit 32 includes a display panel composed of a liquid crystal display (LCD), an organic EL (Organic Electro-Luminescence) panel, and the like, and video and images corresponding to video data supplied from the control unit 22. An image corresponding to the data is displayed on the display panel. The call recording unit 34 is a storage device that stores audio data encoded in a predetermined format, and stores the audio data in a semiconductor such as a flash memory, for example. Note that the call recording unit 34 may be configured integrally with the storage unit 24.

  Next, the incoming call control in the mobile communication device 10 will be described with reference to FIG. FIG. 6 is a sequence diagram illustrating incoming call control after an emergency call.

  In the following description, the third-party communication device means a communication device whose telephone number is not registered in the outgoing / incoming call permission list 24a. The registered communication device means a communication device in which a telephone number is registered in the three-party call origination number 24c, and the emergency destination communication device has a telephone number registered in the emergency destination list 24b. Means communication equipment. In the following description, it is assumed that the user of the registered communication device 50 is the parent of the user of the mobile communication device 10.

  As shown in FIG. 6, it is assumed that an emergency call is made from the mobile communication device 10 to the emergency call destination communication device 41 in accordance with the user's operation as step S12. In this case, the control unit 22 of the mobile communication device 10 switches the mobile communication device 10 to the response restriction relaxation mode for a certain period of time because the telephone number of the call destination is registered in the emergency call destination list 24b.

  In step S13, it is assumed that there is an incoming call from the third-party communication device 40 to the mobile communication device 10 while the mobile communication device 10 is switched to the response restriction relaxation mode. In this case, the control unit 22 of the mobile communication device 10 performs a call between the third party communication device 40 and the mobile communication device 10 as a step S14, the third party communication device 40, the mobile communication device 10, and Transition to a three-party call with the registered communication device 50 is performed.

  In this way, by transferring the call to a three-party call, the parent of the user of the mobile communication device 10 has registered the content of the call exchanged between the third-party communication device 40 and the mobile communication device 10. It can be heard through the communication device 50 and can speak as needed.

  For this reason, even if a malicious third party makes an illegal invitation to the user of the mobile communication device 10, the parent of the user can confirm this through the registered communication device 50 and can immediately stop it. In addition, if a malicious third party knows that the mobile communication device 10 has such a function, it is considered that the malicious third party will not make an unauthorized call to the mobile communication device 10 thereafter. An effect is also obtained.

  Note that the process of transitioning a call between two parties to a three-party call may be realized by calling a function provided in the mobile communication device 10 or calling a function provided in the registered communication device 50. May be realized by calling a function provided by a telephone service company, or may be realized by combining these functions.

  After the transition to the three-party call, in step S15, when a disconnection operation such as an operation of placing the receiver in the registered communication device 50 or an operation of pressing the call stop button is accepted, the mobile communication device 10 and the registered communication device 50 The call between them is disconnected. Then, when the call between the mobile communication device 10 and the registered communication device 50 is disconnected, the control unit 22 immediately disconnects the call between the third-party communication device 40 and the mobile communication device 10 as step S16. Let

  As described above, when the content of the call exchanged between the third-party communication device 40 and the mobile communication device 10 is not appropriate, the registered communication device 50 performs a disconnection operation so that the third-party communication device 40 The call between the mobile communication devices 10 can be forcibly disconnected.

  In addition, when the third party communication device 40 accepts a disconnection operation and the communication between the third party communication device 40 and the mobile communication device 10 is disconnected after the transition to the three-party call, the control unit 22 Then, the call between the mobile communication device 10 and the registered communication device 50 is disconnected. In addition, when the disconnect operation is accepted by the mobile communication device 10, the control unit 22 makes a call between the third-party communication device 40 and the mobile communication device 10, and between the mobile communication device 10 and the registered communication device 50. Disconnect the call.

  And the control part 22 returns the portable communication apparatus 10 to response restriction | limiting mode, after fixed time passes.

  Next, an incoming call control operation of the mobile communication device 10, specifically, an incoming call control operation after an emergency call will be described with reference to FIG. FIG. 7 is a flowchart showing a processing procedure of the mobile communication device 10 in the incoming call control operation after an emergency call. In the following description, it is assumed that the mobile communication device 10 is in the response limit mode.

  When the mobile communication device 10 makes an emergency call to the emergency call destination communication device 41 as step S100, the control unit 22 sets the call destination phone number, the call date and time, and the call end date and time as an emergency call history 24d as step S101. In step S102, the mobile communication device 10 is shifted to the response restriction relaxation mode.

  And control part 22 judges whether the transition period which makes portable communication equipment 10 shift to response restriction mode passed as Step S103. Whether or not the transition period has elapsed is determined, for example, by comparing the difference between the call end date and time of the last emergency call recorded in the emergency call history 24d and the current date and time with a preset transition period. Is done.

  Here, when the transition period has elapsed (step S103, Yes), the control unit 22 causes the portable communication device 10 to transition to the response restriction mode as step S114. On the other hand, if the transition period has not elapsed (No at Step S103), the control unit 22 confirms whether there is an incoming call at the communication unit 26 as Step S104. If there is no incoming call (No at Step S104), the control unit 22 re-executes Step S103 and the subsequent steps.

  When there is an incoming call (step S104, Yes), the control unit 22 determines whether there is an incoming call permission, that is, whether the telephone number of the incoming caller is registered in the outgoing / incoming call permission list 24a as step S105. Here, when the incoming call is permitted (step S105, Yes), the control unit 22 executes a normal incoming call process as step S106, and re-executes step S103 and subsequent steps after the call is completed.

  On the other hand, when there is no incoming call permission (step S105, No), the control unit 22 performs a call with the third party communication device that is the caller of the incoming call, as a step S107, Transition to a three-party call between the communication device 10 and the registered communication device.

  After the transition to the three-party call, the control unit 22 waits for the call to be disconnected by any of the communication devices as step S108. If the call is disconnected by the third party communication device (step S109, Yes), the control unit 22 disconnects the call with the registered communication device as step S110, and re-executes step S103 and subsequent steps. .

  When the call is disconnected by the registered communication device (step S109, No, step S111, Yes), the control unit 22 disconnects the call with the third-party communication device as step S112, and step S103. Then re-execute. When the disconnection operation is accepted in the mobile communication device 10 (step S109, No, step S111, No), the control unit 22 performs a call with the registered communication device and a third party communication device as step S113. The telephone call is disconnected and step S103 and subsequent steps are re-executed.

  As described above, in the first embodiment, when the mobile communication device 10 is switched to the response restriction relaxation mode, the call with the third-party communication device is shifted to the three-party call. In the relaxed mode, it is possible to suppress a decrease in security while permitting an incoming call from an arbitrary communication device.

(Embodiment 2)
In the second embodiment, an example will be described in which a method in which call connection is performed in advance with a registered communication device is used as a method for shifting a call to a three-party call. In the following description, the same parts as those already described are denoted by the same reference numerals as those already described, and redundant description will be omitted.

  In the second embodiment, the control unit 22 transmits to the registered communication device when the mobile communication device 10 is switched to the response restriction relaxation mode, and registers while the mobile communication device 10 is switched to the response restriction relaxation mode. Maintain call connection with finished communication equipment. If there is an incoming call when the mobile communication device 10 is switched to the response restriction relaxation mode, the incoming call and the call connection maintained are transferred to a three-way call.

  In this way, a technique for shifting a call to a three-way call when there is an incoming call while the call connection is maintained has already been put into practical use. For this reason, if this system is used, the function to transfer a call to a three-way call can be easily realized.

  Next, incoming call control in the mobile communication device 10 will be described with reference to FIG. FIG. 8 is a sequence diagram showing incoming call control after an emergency call.

  As shown in FIG. 8, it is assumed that an emergency call is made from the mobile communication device 10 to the emergency call destination communication device 41 in accordance with the user's operation as step S20. In this case, the control unit 22 of the mobile communication device 10 switches the mobile communication device 10 to the response restriction relaxation mode for a certain period of time because the telephone number of the call destination is registered in the emergency call destination list 24b.

  When the portable communication device 10 is switched to the response restriction relaxation mode, the control unit 22 transmits the call to the telephone number registered in the three-party calling number 24c as step S21 and makes a call connection with the registered communication device 50. To keep the call available. This call connection is maintained until the mobile communication device 10 is switched to the response restriction mode. Further, the control unit 22 prohibits the disconnection operation in the mobile communication device 10 until the mobile communication device 10 is switched to the response restriction mode in order to maintain the call connection. Note that “prohibited” here includes not only making the cutting operation impossible, but also ignoring the cutting operation even if the cutting operation is performed.

  In step S22, it is assumed that there is an incoming call from the third party communication device 40 to the mobile communication device 10 while the mobile communication device 10 is switched to the response restriction relaxation mode. In this case, the control unit 22 of the mobile communication device 10 performs a call between the mobile communication device 10 for which call connection has already been established and the registered communication device 50 as a third party communication device 40 in step S23. The three-way call between the mobile communication device 10 and the registered communication device 50 is shifted to.

  After the transition to the three-party call, the control unit 22 receives a disconnection operation in the registered communication device 50 and disconnects the call between the mobile communication device 10 and the registered communication device 50 in step S24. In step S25, the call between the third-party communication device 40 and the portable communication device 10 is disconnected.

  Here, when the mobile communication device 10 is still switched to the response restriction relaxation mode, as a step S26, a call is made to the telephone number registered in the three-party calling number 24c, and a call to the registered communication device 50 is made. Keep the connection available for calls. This call connection is maintained until the mobile communication device 10 is switched to the response restriction mode.

  Then, after a predetermined time has elapsed, the control unit 22 returns the mobile communication device 10 to the response restriction mode, and disconnects the call with the registered communication device 50.

  As described above, when the content of the call exchanged between the third-party communication device 40 and the mobile communication device 10 is not appropriate, the registered communication device 50 performs a disconnection operation so that the third-party communication device 40 The call between the mobile communication devices 10 can be forcibly disconnected. Further, when the disconnection operation is performed in the registered communication device 50 as described above, if the mobile communication device 10 is still in the response restriction relaxation mode, the call connection with the registered communication device 50 is reestablished. When there is a new incoming call from any third party communication device, the call can be transferred to a three-way call.

  Note that the control unit 22 performs the same operation as when the disconnection operation is received by the registered communication device 50, when communication between the mobile communication device 10 and the registered communication device 50 is disconnected due to radio wave interference or the like. Also do. Thereby, even when communication between the mobile communication device 10 and the registered communication device 50 is disconnected due to a failure, the user of the mobile communication device 10 is protected.

  Further, after the transition to the three-party call, when the disconnection operation is accepted by the third party communication device 40 and the call between the third party communication device 40 and the mobile communication device 10 is disconnected, the control unit 22 Until the portable communication device 10 is switched to the response restriction mode, the call connection with the registered communication device 50 is maintained in a state in which a call can be made. By maintaining the call connection with the registered communication device 50 as described above, when a new incoming call is received from any third party communication device, the call can be shifted to a three-party call.

  Next, an incoming call control operation of the mobile communication device 10, specifically, an incoming call control operation after an emergency call will be described with reference to FIG. FIG. 9 is a flowchart showing a processing procedure of the mobile communication device 10 in the incoming call control operation after an emergency call. In the following description, it is assumed that the mobile communication device 10 is in the response limit mode.

  When the mobile communication device 10 makes an emergency call to the emergency call destination communication device 41 as step S200, the control unit 22 sets the call destination telephone number, the call date / time, and the call end date / time as an emergency call history 24d as step S201. In step S202, the mobile communication device 10 is shifted to the response restriction relaxation mode. Subsequently, the control unit 22 transmits to the registered communication device in step S203, and prohibits the disconnection operation in the mobile communication device 10 in step S204.

  And control part 22 judges whether the transition period which makes portable communication equipment 10 shift to response restriction mode passed as Step S205. Whether or not the transition period has elapsed is determined, for example, by comparing the difference between the call end date and time of the last emergency call recorded in the emergency call history 24d and the current date and time with a preset transition period. Is done.

  Here, when the transition period has elapsed (step S205, Yes), the control unit 22 disconnects the call as step S212, causes the portable communication device 10 to transition to the response restriction mode as step S213, and proceeds to step S214. As described above, the cutting operation in the mobile communication device 10 is permitted.

  On the other hand, if the transition period has not elapsed (No at Step S205), the control unit 22 confirms whether there is an incoming call at the communication unit 26 as Step S206. If there is no incoming call (No at Step S206), the control unit 22 re-executes Step S205 and the subsequent steps.

  If there is an incoming call (step S206, Yes), the control unit 22 carries out a call with the already-registered registered communication device as a step S207 with the third-party communication device that is the caller of the incoming call, Transition to a three-party call between the communication device 10 and the registered communication device.

  After the transition to the three-party call, the control unit 22 waits for the call to be disconnected by any of the communication devices in step S208. When the call is disconnected by the third party communication device (step S209, Yes), the control unit 22 re-executes step S205 and subsequent steps while maintaining the call with the registered communication device.

  When the call is disconnected by the registered communication device (No at Step S209), the control unit 22 disconnects the call with the third-party communication device as Step S210. Subsequently, in step S211, the control unit 22 transmits to the registered communication device, restarts the call with the registered communication device, and re-executes step S205 and the subsequent steps.

  As described above, in the second embodiment, since the mobile communication device 10 performs call connection with the registered communication device in advance, the transition to the three-party call is easily realized, In the response restriction alleviation mode, it is possible to prevent a decrease in security while permitting an incoming call from any communication device.

(Embodiment 3)
In the third embodiment, an example in which a method of transferring an incoming call from a third-party communication device to a registered communication device will be described as a method for shifting a call to a three-party call.

  In the third embodiment, when there is an incoming call from a third party communication device when the mobile communication device 10 is switched to the response restriction relaxation mode, the control unit 22 transfers the incoming call to the registered communication device, and the third A call is established between the person communication device and the registered communication device. Then, the control unit 22 causes the call between the third party communication device and the registered communication device to shift to a three-party call including the mobile communication device 10 by responding to an incoming call from the registered communication device.

  Such a technique for transferring an incoming call has already been put into practical use. For this reason, if this system is used, the function to transfer a call to a three-way call can be easily realized.

  Next, a schematic configuration of functions of the registered communication device 50 will be described. FIG. 10 is a block diagram illustrating a schematic configuration of functions of the registered communication device 50. The registered communication device 50 is a communication device in which a telephone number is registered in the three-party call origination number 24 c of the mobile communication device 10. The registered communication device 50 may be a mobile phone device or a fixed phone device.

  As shown in FIG. 10, the registered communication device 50 includes a control unit 62, a storage unit 64, a communication unit 66, an operation unit 68, a voice processing unit 70, a display unit 72, a call recording unit 74, Have

  The memory | storage part 64 is a memory | storage device which memorize | stores various information, for example, memorize | stores information in semiconductors, such as flash memory. The storage unit 64 stores application programs and data used for processing in the control unit 62. For example, the storage unit 64 stores a three-party call target telephone number 64b as data.

  The three-party call target telephone number 64b is data in which the telephone number of the mobile communication device 10 in which the telephone number of the registered communication device 50 is registered in the three-party call transmission number 24c is registered. An example of a three-party call target telephone number 64b is shown in FIG. In the three-party call target telephone number 64b shown in FIG. 11, one telephone number is registered, and “Hanako” is included in the telephone number so that the owner of the communication device corresponding to the telephone number can be easily identified. Is associated. The three-party call target telephone number 64b is created and updated by an operation of a user of the registered communication device 50, for example.

  The control unit 62 is a processing unit, such as a CPU, that comprehensively controls the overall operation of the registered communication device 50. That is, the communication unit 66, so that various processes of the registered communication device 50 are executed in an appropriate procedure according to the operation of the operation unit 68 and the software stored in the storage unit 64 of the registered communication device 50. The operation of the display unit 72 and the like is controlled. The control unit 62 executes processing based on a program (for example, an operating system program, application program, etc.) stored in the storage unit 64. The control unit 62 can execute a plurality of programs (applications, software) in parallel.

  As a part of control of the operation of the registered communication device 50, the control unit 62 sends a call to the transfer source when a transfer is received with the phone number registered in the three-party call target phone number 64b as the transfer source. Then, the transferred call is transferred to a three-way call including the transfer source.

  The communication unit 66 performs telephone communication and information communication by wireless communication or wired communication. The operation unit 68 includes various keys, and when these keys are input by a user operation, a signal corresponding to the operation content is generated. The generated signal is input to the control unit 62 as a user instruction.

  The audio processing unit 70 performs processing of an audio signal input to the microphone 55 and an audio signal output from the receiver 56. The display unit 72 includes a display panel configured by a liquid crystal display, an organic EL panel, or the like, and displays a video corresponding to the video data supplied from the control unit 62 and an image corresponding to the image data on the display panel. The call recording unit 74 is a storage device that stores audio data encoded in a predetermined format, and stores the audio data in a semiconductor such as a flash memory, for example. Note that the call recording unit 74 may be configured integrally with the storage unit 64.

  Next, the incoming call control in the mobile communication device 10 and the registered communication device 50 will be described with reference to FIG. FIG. 12 is a sequence diagram illustrating incoming call control after an emergency call.

  As shown in FIG. 12, it is assumed that an emergency call is made from the mobile communication device 10 to the emergency call destination communication device 41 in accordance with the operation of the user as step S30. In this case, the control unit 22 of the mobile communication device 10 switches the mobile communication device 10 to the response restriction relaxation mode for a certain period of time because the telephone number of the call destination is registered in the emergency call destination list 24b.

  In step S31, it is assumed that there is an incoming call from the third-party communication device 40 to the mobile communication device 10 while the mobile communication device 10 is switched to the response restriction relaxation mode. In this case, the control unit 22 transfers the incoming call from the third party communication device 40 to the registered communication device 50 in which the telephone number is registered in the three-party call transmission number 24c as step S32. By this transfer, a call between the third party communication device 40 and the registered communication device 50 is established.

  Subsequently, since the transfer source telephone number of the incoming transfer is registered in the three-party call target telephone number 64b, the control unit 62 of the registered communication apparatus 50 determines in step S33 the mobile communication apparatus 10 that is the incoming call source. To the three-party call between the third-party communication device 40, the mobile communication device 10, and the registered communication device 50. Transition.

  In this way, by transferring the call to a three-party call, the parent of the user of the mobile communication device 10 has registered the content of the call exchanged between the third-party communication device 40 and the mobile communication device 10. It can be heard through the communication device 50 and can speak as needed.

  After the transition to the three-party call, when a disconnection operation is accepted in the registered communication device 50 as step S34, the call between the mobile communication device 10 and the registered communication device 50 is disconnected and a third-party communication device. The call between the registered communication device 50 and the registered communication device 50 is disconnected, and the call between the registered communication device 50 and the portable communication device 10 becomes impossible.

  As described above, when the content of the call exchanged between the third-party communication device 40 and the mobile communication device 10 is not appropriate, the registered communication device 50 performs a disconnection operation so that the third-party communication device 40 The call between the mobile communication devices 10 can be forcibly disconnected.

  Note that if the disconnection operation is accepted by the third-party communication device 40 or the mobile communication device 10 and the call with the registered communication device 50 is disconnected, the registered communication device 50 is the remaining communication device. The call may be continued or disconnected.

  Next, an incoming call control operation of the mobile communication device 10, specifically, an incoming call control operation after an emergency call will be described with reference to FIG. FIG. 13 is a flowchart showing a processing procedure of the mobile communication device 10 in the incoming call control operation after an emergency call. In the following description, it is assumed that the mobile communication device 10 is in the response limit mode.

  When the mobile communication device 10 makes an emergency call to the emergency call destination communication device 41 as step S300, the control unit 22 sets the call destination phone number, the call date and time, and the call end date and time as an emergency call history 24d as step S301. In step S302, the mobile communication device 10 is shifted to the response restriction relaxation mode.

  Then, the control unit 22 determines whether or not a transition period for shifting the mobile communication device 10 to the response restriction mode has elapsed in step S303. Whether or not the transition period has elapsed is determined, for example, by comparing the difference between the call end date and time of the last emergency call recorded in the emergency call history 24d and the current date and time with a preset transition period. Is done.

  Here, when the transition period has elapsed (step S303, Yes), the control unit 22 causes the mobile communication device 10 to transition to the response restriction mode as step S309.

  On the other hand, if the transition period has not elapsed (No at Step S303), the control unit 22 checks whether there is an incoming call at the communication unit 26 as Step S304. When there is no incoming call (No at Step S304), the control unit 22 re-executes Step S303 and the subsequent steps.

  When there is an incoming call (step S304, Yes), the control unit 22 determines whether the incoming call source is a registered communication device as step S305. If the incoming call source is not a registered communication device (No at Step S305), the control unit 22 transfers the incoming call to the registered communication device as Step S306, and re-executes Step S303 and the subsequent steps. This transfer is performed in order to establish a call between the third party communication device and the registered communication device and to obtain a return call from the registered communication device.

  On the other hand, when the incoming call source is a registered communication device (step S305, Yes), the control unit 22 performs normal incoming call processing as step S307. If the incoming call from the registered communication device is triggered by the incoming call transfer from the mobile communication device 10, a three-way call is established by this incoming call process.

  In step S308, the control unit 22 waits for the call to be disconnected by the mobile communication device 10 or the registered communication device. If the call is disconnected (step S308, Yes), step S303 and subsequent steps are re-executed. To do.

  Next, the incoming call control operation of the registered communication device 50 will be described with reference to FIG. FIG. 14 is a flowchart showing a processing procedure in the incoming call control operation of the registered communication device 50. The control unit 62 of the registered communication device 50 repeatedly executes the processing procedure shown in FIG. 14 while the incoming call function is valid.

  The control unit 62 of the registered communication device 50 waits for an incoming call in step S320. When there is an incoming call (step S320, Yes), the control unit 62 determines whether the incoming call has been transferred as step S321. Here, if the incoming call has not been transferred (step S321, No), the control unit 62 executes a normal incoming call process as step S322.

  If the incoming call has been transferred (step S321, Yes), the control unit 62 compares the transfer source telephone number with the telephone number registered in the three-party call target telephone number 64b as step S323. If the telephone numbers do not match (step S324, No), the control unit 62 executes normal incoming processing as step S322.

  On the other hand, if the transfer source telephone number matches the telephone number registered in the three-party call target telephone number 64b (step S324, Yes), the control unit 62 executes the incoming call processing as step S325, In S326, a call is made to the transfer source to establish a three-party call.

  As described above, in the third embodiment, the mobile communication device 10 transfers the incoming call from the third party communication device to the registered communication device and receives the incoming call from the registered communication device, thereby establishing a three-party call. Therefore, it is possible to easily realize a transition to a three-party call, and to suppress a decrease in security while permitting an incoming call from any communication device in the response restriction relaxation mode.

(Embodiment 4)
In the fourth embodiment, an example will be described in which the contents of a three-party call are recorded in a registered communication device. In the following description, the method described in the second embodiment is used as a method for transferring a call to a three-party call. However, when a call is transferred to a three-party call by another method, three methods are similarly used. It is possible to record the content of a call in a person call in a registered communication device.

  In the fourth embodiment, when the mobile communication device 10 switches to the response restriction relaxation mode, the control unit 22 of the mobile communication device 10 transmits to the registered communication device, and the mobile communication device 10 switches to the response restriction relaxation mode. While connected, the call connection with the registered communication device is maintained. If there is an incoming call when the mobile communication device 10 is switched to the response restriction relaxation mode, the incoming call and the call connection maintained are transferred to a three-way call.

  In addition, when the call with the registered communication device is disconnected while switching to the response restriction relaxation mode, the control unit 22 causes the call recording unit 34 to record the content of the call with a communication device other than the registered communication device. . The content of the call recorded in the call recording unit 34 is subsequently transmitted to the registered communication device by transmission by e-mail or transmission via the server device of the telephone service company.

  In this way, when the call with the registered communication device is disconnected for some reason, the call content is recorded and transmitted to the registered communication device, so that the user of the registered communication device can postulate the call content after the disconnection. It is possible to check the security, and it is possible to suppress a decrease in security caused by switching the mobile communication device 10 to the response restriction relaxation mode so as to be able to respond to an incoming call from any source.

  In the fourth embodiment, the control unit 62 of the registered communication device 50 receives an incoming call from the phone number registered in the three-party call target phone number 64b as part of the control of the operation of the registered communication device 50. If the user does not respond to the incoming call or ringing with vibration, the incoming call is accepted and the call recording unit 74 records the call content. Further, when the call recording unit 74 runs out of capacity while the call recording unit 74 is recording the call content, the control unit 62 allows the call source recording device to take over the recording of the call content.

  Here, if the telephone number of the mobile communication device 10 is registered in the three-party call target phone number 64b, the contents of the call are recorded, so the user of the registered communication device 50 cannot respond to an incoming call for some reason. Even in this case, the contents of the call between the mobile communication device 10 and the third party communication device can be confirmed afterwards. As a result, it is possible to suppress a decrease in security caused by switching the mobile communication device 10 to the response restriction relaxation mode so as to be able to respond to incoming calls from any source.

  Next, the incoming call control in the mobile communication device 10 and the registered communication device 50 will be described with reference to FIG. FIG. 15 is a sequence diagram illustrating incoming call control after an emergency call.

  As shown in FIG. 15, it is assumed that an emergency call is made from the mobile communication device 10 to the emergency call destination communication device 41 in accordance with the user's operation as step S40. In this case, the control unit 22 of the mobile communication device 10 switches the mobile communication device 10 to the response restriction relaxation mode for a certain period of time because the telephone number of the call destination is registered in the emergency call destination list 24b.

  When the portable communication device 10 is switched to the response restriction relaxation mode, the control unit 22 transmits the call to the telephone number registered in the three-party call number 24c as step S41, and makes a call connection with the registered communication device 50. To keep the call available. This call connection is maintained until the mobile communication device 10 is switched to the response restriction mode. Further, the control unit 22 prohibits the disconnection operation in the mobile communication device 10 until the mobile communication device 10 is switched to the response restriction mode in order to maintain the call connection.

  On the other hand, if the user does not respond to the incoming call of the mobile communication device 10 whose telephone number is registered in the three-party call target phone number 64b, the control unit 62 of the registered communication device 50 receives the incoming call as step S42. The call content is received and recorded in the call recording unit 74.

  In step S43, it is assumed that there is an incoming call from the third party communication device 40 to the mobile communication device 10 while the mobile communication device 10 is switched to the response restriction relaxation mode. In this case, the control unit 22 of the mobile communication device 10 performs a call between the mobile communication device 10 for which call connection has already been established and the registered communication device 50 as a third party communication device 40 in step S44. The three-way call between the mobile communication device 10 and the registered communication device 50 is shifted to.

  In this way, by transferring the call to a three-party call, the content of the call exchanged between the third party communication device 40 and the portable communication device 10 by the parent of the user of the portable communication device 10 has been registered. It is recorded in the call recording unit 74 of the communication device 50.

  After the transition to the three-party call, when the disconnect operation is accepted by the third party communication device 40 and the call between the third party communication device 40 and the mobile communication device 10 is disconnected, the control unit 22 Until the device 10 switches to the response restriction mode, the call connection with the registered communication device 50 is maintained in a state in which a call can be made. By maintaining the call connection with the registered communication device 50 as described above, when a new incoming call is received from any third party communication device, the call can be shifted to a three-party call.

  Then, after a predetermined time has elapsed, the control unit 22 returns the mobile communication device 10 to the response restriction mode, and disconnects the call with the registered communication device 50. When the call is disconnected, the control unit 62 of the registered communication device 50 ends the call content recording.

  If the capacity of the call recording unit 74 is insufficient during recording of the call content, the control unit 62 of the registered communication device 50 stops the call content recording and disconnects the call as shown in FIG. When the communication with the registered communication device 50 is disconnected while the control unit 22 of the mobile communication device 10 is switched to the response restriction relaxation mode, the content of the call with the third-party communication device 40 is called as step S45. Recording is performed in the recording unit 34.

  When the recording of the call content is stopped, the control unit 62 transmits a predetermined signal to the mobile communication device 10 and explicitly requests the mobile communication device 10 to take over the call content recording. Also good.

  Thereafter, while the mobile communication device 10 is switched to the response restriction relaxation mode, the disconnect operation is accepted by the third party communication device 40 and the call between the third party communication device 40 and the mobile communication device 10 is disconnected. Shall be. In this case, the control unit 22 ends the recording of the call content. After that, the control unit 22 may switch the mobile communication device 10 to the response restriction mode, or allow incoming calls from a third party communication device and record the call contents until a certain time elapses. It is good also as making the part 34 record.

  Next, an incoming call control operation of the mobile communication device 10, specifically, an incoming call control operation after an emergency call will be described with reference to FIG. FIG. 16 is a flowchart showing a processing procedure of the mobile communication device 10 in the incoming call control operation after an emergency call. In the following description, it is assumed that the mobile communication device 10 is in the response limit mode.

  When the mobile communication device 10 makes an emergency call to the emergency call destination communication device 41 as step S400, the control unit 22 sets the call destination telephone number, the call date and time, and the call end date and time as an emergency call history 24d as step S401. In step S402, the mobile communication device 10 is shifted to the response restriction relaxation mode. Subsequently, the control unit 22 transmits to the registered communication device in step S403, and prohibits the disconnection operation in the mobile communication device 10 in step S404.

  And control part 22 judges whether the transition period which shifts portable communication apparatus 10 to response restriction mode passed as Step S405. Whether or not the transition period has elapsed is determined, for example, by comparing the difference between the call end date and time of the last emergency call recorded in the emergency call history 24d and the current date and time with a preset transition period. Is done.

  If the transition period has elapsed (step S405, Yes), the control unit 22 determines whether the call content is being recorded as step S415. And if it is during recording (step S415, Yes), the control part 22 will end recording as step S412, will make the portable communication apparatus 10 transfer to response restriction | limiting mode as step S413, and will perform portable communication as step S414. The cutting operation at the device 10 is permitted. If recording is not in progress (No at Step S415), the control unit 22 disconnects the call at Step S416, shifts the mobile communication device 10 to the response restriction mode at Step S413, and moves the mobile communication device 10 to Step S414. Allows disconnection operation at.

  On the other hand, if the transition period has not elapsed (step S405, No), as step S406, the control unit 22 confirms whether the communication unit 26 has an incoming call. If there is no incoming call (No at Step S406), the control unit 22 re-executes Step S405 and the subsequent steps.

  When there is an incoming call (step S406, Yes), the control unit 22 carries out a call with the already-registered registered communication device as a step S407 with a third-party communication device that is the source of the incoming call, Transition to a three-party call between the communication device 10 and the registered communication device.

  After the transition to the three-party call, the control unit 22 waits for the call to be disconnected by any of the communication devices in step S408. When the call is disconnected by the registered communication device (step S409, Yes), the control unit 22 starts recording the call content as step S410, and re-executes step S408 and subsequent steps.

  When the call is disconnected by the third party communication device (No at Step S409), the control unit 22 determines whether the call content is being recorded as Step S411. Here, if recording is in progress (step S411, Yes), since the call with the already registered communication device has been disconnected, the control unit 22 ends the recording as step S412, and the portable communication as step S413. The device 10 is shifted to the response restriction mode, and disconnection operation in the mobile communication device 10 is permitted as step S414.

  On the other hand, if the recording is not in progress (step S411, No), since the call with the registered communication device is maintained, the control unit 22 re-executes step S405 and the subsequent steps.

  Next, the incoming call control operation of the registered communication device 50 will be described with reference to FIG. FIG. 17 is a flowchart showing the processing procedure of the incoming call control operation of the registered communication device 50. The control unit 62 of the registered communication device 50 repeatedly executes the processing procedure shown in FIG. 17 while the incoming call function is valid.

  The control unit 62 of the registered communication device 50 waits for an incoming call in step S420. When there is an incoming call (step S420, Yes), the control unit 62 compares the telephone number of the incoming call source with the telephone number registered in the three-party call target telephone number 64b as step S421. If the telephone numbers do not match (step S422, No), the control unit 62 executes normal incoming call processing as step S423.

  On the other hand, when the telephone number of the incoming call and the telephone number registered in the three-party call target telephone number 64b match (Yes in step S422), the control unit 62 determines whether the user has received a ringtone, vibration, or the like as step S424. And ask to answer incoming calls. If a response to the incoming call is made (step S425, Yes), the control unit 62 executes a normal incoming call process as step S423.

  When the response to the incoming call is not made (step S425, No), the control unit 62 performs an incoming call process to accept the incoming call as step S426, and starts recording the content of the call as step S427. Then, in step S428 and step S430, the control unit 62 waits until the call is disconnected or the capacity of the call recording unit 74 is full.

  When the call is disconnected (step S428, Yes), the control unit 62 ends the recording of the call content as step S429. When the capacity of the call recording unit 74 becomes full (step S430, Yes), the control unit 62 disconnects the call as step S431.

  As described above, in the fourth embodiment, since the registered communication device 50 and the mobile communication device 10 record the call contents, the user of the registered communication device 50 cannot respond to the incoming call. However, in the response restriction alleviation mode, it is possible to prevent a decrease in security while permitting an incoming call from any communication device.

(Other embodiments)
The configuration of the various communication devices in each of the above embodiments can be variously changed without departing from the gist. For example, if a call is disconnected by a registered communication device during a three-way call, the mobile communication device will change the phone number of the third-party communication device to a list of phone numbers that will be rejected even in response restriction relaxation mode. It may be registered. With this configuration, it is not necessary to deal with incoming calls from malicious third parties many times.

  In the first to fourth embodiments, the mobile communication device is switched from the response restriction mode to the response restriction relaxation mode for a certain period of time in response to an emergency call. The mobile communication device may be switched from the response restriction mode to the response restriction mitigation mode for a certain period of time when a call is made to a telephone number that is not registered.

  In Embodiments 1 to 4, when the mobile communication device is switched from the response restriction mode to the response restriction relaxation mode in response to an emergency call, the call with the third party communication device is shifted to a three-party call. Even when the mobile communication device is switched from the response restriction mode to the response restriction relaxation mode by the user's operation, the call with the third party communication device may be shifted to the three-party call.

  In the second embodiment, the registered communication device disconnects the call during the three-party call in order to end the three-party call from the registered communication device side. When it is necessary to terminate a person's call, a specific signal is transmitted from the registered communication device to the mobile communication device, and when the mobile communication device receives the specific signal, the call with the registered communication device is maintained. It is also possible to disconnect only the call with the third-party communication device.

  Further, in the second embodiment, when a registered communication device disconnects a call during a three-party call, the mobile communication device disconnects the call with the third-party communication device, and then transmits again to the registered communication device. However, if a registered communication device disconnects the call during a three-party call, the mobile communication device must disconnect the call with the third-party communication device and then make a call to the registered communication device. It is also possible to shift to the response limit mode.

  In the third embodiment, when there is a transfer from a telephone number registered in advance, the registered communication device automatically makes a call to the transfer source. However, the transfer from the telephone number registered in advance is performed. If there is, the registered communication device displays a screen asking whether or not to execute the call to the transfer source, and if the user selects to execute the call, the call is made to the transfer source. Also good. With this configuration, a user of a registered communication device can determine whether or not a three-party call is necessary after confirming the requirements for incoming calls from a third-party communication device.

  In the fourth embodiment, when the user does not respond to an incoming call from a specific telephone number, the registered communication device accepts the incoming call and starts recording the content of the call. Even in this case, the content of the call may be recorded constantly or only for the period instructed by the user. When recording the content of a call, recording may be stopped in the silent section. With this configuration, the capacity of recorded data can be saved.

  As described above, the mobile communication device and the incoming call control method according to the present invention are useful when receiving an incoming call from an arbitrary source, and in particular, receiving an incoming call from an arbitrary source. It is suitable when it is necessary to suppress a decrease in security.
