Description

  The present invention relates to a transmission / reception system including a portable transmission / reception device and a non-portable transmission / reception device.

  As a prior art related to a transmission / reception system including a portable transmission / reception device and a non-portable transmission / reception device, for example, there is one described in Patent Document 1.

  In this prior art, a portable transmitter / receiver (in this example, a mobile phone) is arranged in an external radio wave receivable area in a company building.

When the mobile phone receives an incoming call, the main unit notifies the corresponding non-portable handset device (button phone in this example) of the incoming call, and forms a call path connecting them. Thus, it is possible to respond to an incoming call to the mobile telephone by means of a button telephone.
JP 2000-287234 A (paragraph numbers 0006 to 0029, FIG. 1)

  The prior art has the following problems.

  In other words, there is a general recognition that portable handset devices are very strong in connection with the owner (full-time user) due to the nature of being portable.

  For this reason, a person who has made a call to a portable handset tends to have a thought that a full-time user is naturally speaking at the stage where the other party has received a response.

  However, in the case where the incoming call at the portable transmission / reception device can be answered by the non-portable transmission / reception device as in the prior art, the full-time user does not always respond.

  When an incoming call at a portable handset is notified to a non-portable handset, whether surrounding people, including full-time users, have arrived directly at the non-portable handset as usual, This is because it is impossible to distinguish whether the call is received by the portable handset device as described above.

  For this reason, there is a possibility that another person (third party) may be careful and respond to the incoming call from the non-portable transmitter / receiver while the full-time user happens to be absent.

  In such a case, since the person who made the transmission has the above-mentioned feelings, there is a concern that the full-time user will inadvertently talk about personal matters and information that other people do not want to know, Convenience was poor in terms of ensuring privacy.

  An object of the present invention is to provide a transmission / reception system capable of ensuring privacy and improving usability even when an incoming call at a portable transmission / reception device can be answered by a non-portable transmission / reception device.

The invention of claim 1 is a transmission / reception system, which is a portable transmission / reception device having a transmission / reception function via wireless communication, and a call for answering an incoming call when the portable transmission / reception device receives an incoming call. A non-portable transmitter / receiver device associated through wireless communication so as to be enabled, and the answering call to the incoming call of the portable transmitter / receiver device by the non-portable transmitter / receiver device, a predetermined specific condition A call restriction permission unit that restricts and permits the call when the condition is satisfied, the call restriction permission unit determining whether the off-hook state is established within a predetermined time range, and a determination result of the determination unit And a first call control means for controlling whether or not the answering call is possible.
When an incoming call is received by the portable transmission / reception device, the call control means controls whether or not a response call is possible according to the determination result of the determination means.
As a result, it becomes possible to make a response call when it is in an off-hook state within a predetermined time range, and to make a response call impossible otherwise.
As a result, it is possible to prevent a third party who does not enter the off-hook state within the predetermined time range from responding, and to ensure necessary privacy and improve usability .
請 Motomeko 2 invention is a handset system response, a portable handset apparatus having a handset function through the wireless communication, for that call when there is an incoming call to the portable handset device A non-portable transmitter / receiver associated through wireless communication so as to be able to make a call, and a response call for the incoming call of the portable transmitter / receiver by the non-portable transmitter / receiver. Call restriction permission means for restricting and permitting when the condition is satisfied, and the call restriction permission means includes feature information detection means for detecting feature information of the specific person, and feature information detection means And a second call control means for controlling whether or not the answering call is possible according to a detection result.

  According to the present invention, since the answering call is restricted and permitted when a specific condition preset by the call restriction permitting means is satisfied, the incoming call at the portable handset is accepted by the non-portable handset. Even when response is possible, privacy can be ensured and usability can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  This embodiment is an embodiment when the present invention is applied to a button telephone system including a so-called main device and a slave unit.

  FIG. 1 is a block diagram showing the overall configuration of a transmission / reception system (button telephone system) of this embodiment.

  In FIG. 1, this button telephone system includes a main device 1 connected to at least one telephone line 11 and a plurality of non-portable handset devices connected to the control device 1 via an extension transmission line 3. A portable transmission associated with a slave unit (button telephone) 2 via wireless communication (in this example, one-to-one) so that a responding call can be made with the slave unit 2 corresponding to the incoming call when the incoming call is received. And a mobile phone 40 as a receiver.

  The main device 1 exchanges an external line interface unit 12 for terminating the telephone line 11, an internal line interface unit 13 connected to the slave unit 2 via the internal line transmission path 3, and the external line interface unit 12 and the internal line interface unit 13. The exchange processing unit 14 to be connected, the state of the telephone line 11 and the handset 2, the main control unit 15 for controlling the entire apparatus, and the main memory for storing various control information necessary for control by the main control unit 15 Device 16.

  The subunit | mobile_unit 2 decodes the audio | voice data received by the transmission interface part 21 which performs data transmission with the main apparatus 1 via the extension transmission line 3, and the transmission interface part 21 into an audio | voice signal, and is a handset or a speaker (not shown). ), A communication circuit 22 that encodes voice input from the handset into voice data and outputs the voice data to the transmission interface unit 21, a control unit 23 that controls each unit of the slave unit 2, a flash key, a hook switch, and a dial An operation input unit 24 that detects operations of various keys such as keys, a display unit 25 that displays various types of information in characters and figures, a memory 26 that stores control information used in processing of the slave unit control unit 23, and an antenna 32A And a wireless interface unit 32 that performs data communication with a mobile phone 40 that is paired by wireless communication.

  The communication circuit 22 is provided with a sound source such as a ringtone that is displayed when an incoming call is received, and is controlled by the handset controller 23 based on data with the main device 1.

  In the display unit 25, for example, an external line signal or the like is displayed in characters / designs by the slave unit control unit 23 based on data transmission with the main apparatus 1.

  The cellular phone 40 has a wireless interface unit 41 that performs data communication with the corresponding handset 2 via wireless communication via an antenna 41A, a voice call function using a speaker and a microphone (not shown), and a function for generating various notification sounds. Supplied from a predetermined charger (may be provided in the slave unit 2) via a charging terminal (not shown) and a battery 43 that stores an operating power source used in each part of the mobile phone 40. Charging unit 44 that charges the battery 43 with the power, a storage unit (memory) 46 that stores various information and programs used in processing operations by a control unit 49 (described later), and instructions received from the slave unit 2 by data communication For example, a display unit 47 that controls various LEDs and LCDs to perform various displays, a key input unit (operation input unit) 48 that detects a key operation by a user (owner), and a CPU or the like. Black has a processor, by reading and executing a program stored in the storage unit 46, and a control unit 49 that controls each unit of the mobile phone 40 in cooperation with the hardware.

  In the above configuration, the main part of the present embodiment is that the answering call for the incoming call of the mobile phone 40 by the handset 2 is limited and permitted when a specific condition set in advance is satisfied.

  The details will be described below with reference to FIG.

  FIG. 2 is an operation flow showing a control operation executed by the cooperation of the main control unit 15 of the main device 1, the child device control unit 23 of the child device 2, and the control unit 49 of the mobile phone 40.

  In FIG. 2, first, when there is an external incoming call to the mobile phone 40, an incoming call notification signal to that effect is transmitted from the mobile phone 40 to the handset 2 (step S1), and the handset 2 responds accordingly to the mobile phone 40. A ring tone indicating that there is an incoming call is generated (step S2).

  This ringing tone is different from the ringing tone at the time of an incoming call at the handset 2 via the main device 1 (via a wired telephone line). Sounds that are not changed but have different timbres (higher frequency sounds, lower frequency sounds, intermittent sounds, etc.), and at least the dedicated users of the mobile phone 40 and the slave unit 2 are connected to the mobile phone 40 It should be easy to understand that a call has arrived.

  In this case, a ring tone specific to the mobile phone 40 generated by the voice processing unit 42 of the mobile phone 40 (using this as a sound source) is sent to the handset 2 by wireless communication so that the handset 2 rings. Alternatively, sound data (for example, a known MIDI file) is generated by the sound processing unit 42 and transmitted to the child device 2, and the sound source itself is caused to ring using the communication circuit 22 of the child device 2. May be.

  Thereafter, a notification signal indicating that the child device 2 is in use is issued from the child device 2 to the main device 1 (step S3).

  In response to this, the main device 1 performs a predetermined control process (for example, blocking the connection path to the slave unit 2) as necessary.

  When the handset 2 is put into an off-hook state in response to the incoming call ringing (operation P1), a signal to that effect is transmitted to the main device 1 (step S4).

In this example, the main apparatus 1 does not perform any special control on this signal.

  Here, in this example, in the handset 2, when the mobile phone ringing as described above, if the mobile phone 2 does not perform a preset specific operation (special number operation or special key operation), the mobile phone The condition is set so that the incoming call to 40 cannot be answered.

  When the special number operation or the like corresponding to this setting is performed (operation P2), the above conditions are satisfied and a line is formed through wireless communication between the handset 2 and the mobile phone 40 (step S5). To the other party can be answered from the handset 2 via the mobile phone 40.

  Thereafter, when the answering call is finished and the handset 2 is in an on-hook state (operation P3), wireless communication from the handset 2 to the mobile phone 40 is interrupted (step S6), and the mobile phone 40 is in the end state.

  Further, a signal indicating that the slave unit 2 is in an on-hook state is transmitted to the main device 1 (step S7), and the main device 1 reconnects a predetermined use canceling process (for example, a connection path to the slave unit 2 as necessary). Etc.).

  In the above operation flow, the generation of the control signal may be shared by the main control unit 15 of the main device 1, the slave unit control unit 23 of the slave unit 2, and the control unit 49 of the mobile phone 40. In addition, the generated signal may be exchanged in any way, and as a result, the above operation is sufficient.

  Then, as described above, the control performed in step S2 for ringing a ringtone different from that in the normal mode is different in volume or tone from the other cases when an incoming call is received by the portable handset. This is equivalent to sound control means for performing control so that notification from a non-portable transmitter / receiver is performed, and limited notification means for notifying a mobile phone receiver / receiver that an incoming call has been received to a specific person. Further, it corresponds to a caller restriction means for restricting a person who can answer a call to a specific person set in advance.

  Also, in a broad sense, it corresponds to a call restriction permission means for restricting and accepting a response call to an incoming call of a portable handset device by a non-portable handset device when a predetermined condition is satisfied. .

  Further, when a mobile incoming call is ringed in operation P2, an incoming call answering call cannot be made to the mobile phone 40 unless a predetermined operation (special number operation or special key operation) is performed. The condition setting control is performed in accordance with the key operation detecting means for detecting a key operation in a predetermined mode, and whether or not the answering call is possible is controlled according to the detection result of the key operation detecting means. Corresponds to the first call control means, and also corresponds to call condition limiting means for enabling a response call when a specific operation state set in advance is executed, and in a broad sense, non-portable transmission / reception This also corresponds to call restriction permission means for restricting and permitting a response call to an incoming call of the portable transmission / reception device by a device when a predetermined condition is satisfied.

  As described above, in the key telephone system of the present embodiment, when an incoming call is received at the mobile phone 40, the incoming call is received from the handset 2 using a volume or tone color that is different from the normal at step S1. Is limited to a full-time user of the handset 2.

  As a result, it is possible to prevent other than the full-time user from noticing (or not easily recognizing) that the incoming call has been received.

  Further, when a response call is made from the handset 2 to this incoming call, a response call can be made by performing a preset specific operation (special number operation or special key operation) as in operation P2. If such a specific operation is not executed, it is impossible to make a response call.

  As described above, the third party does not notice that the incoming call has arrived at the mobile phone 40 (it is difficult to notice), and even if it is noticed, it cannot respond unless a specific operation is performed. It is possible to prevent a third party other than the full-time user 40 and the slave unit 2 from inadvertently responding to an incoming call. As a result, necessary privacy can be ensured and usability can be improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described.

(1) A normal ringing tone or a special number operation or the like, which is different from the normal one. As described in the above step S2, the normal user can easily understand that the full-time user has received the mobile phone 40. When a different incoming ringing is performed, this special number operation is not necessarily required during a response call from the viewpoint of preventing an inadvertent response by a third party (it may be possible to respond by a normal operation) ). Also in this case, at least as compared with the conventional configuration in which the handset 2 has no particular difference between the mobile incoming call and the normal incoming call, an effect of preventing an inadvertent response by a third party can be obtained.

  Or, conversely, if a special number operation for responding to the mobile phone shown in the above operation 2 is necessary at the time of response, it is not always necessary to ring the mobile ringing tone in the above-described step S2, and the main device 1 is not connected. It is also possible to use the same ringing tone as that received by the normal handset 2 (via a wired telephone line). In this case as well, the effect of preventing an inadvertent response by a third party can be obtained as compared with at least the conventional configuration.

(2) Instead of sound control, another notification mode is used. That is, instead of ringing a unique ringing tone to the effect that the mobile phone 40 has received an incoming call in step S2, another mode, for example, no sound is generated. It is possible to display only a predetermined mode of incoming call display (lamp etc.) without ringing, or to perform a flashing display / color display different from a normal incoming call display (such a control mode is described in each claim). Equivalent to display control means). Alternatively, an appropriate vibration unit may be built in the slave unit 2 and the slave unit 2 itself may vibrate (such a control mode corresponds to the vibration control unit described in each claim).

(3) Time Limit Substituting for Special Number Operation In other words, in the above embodiment, the portable unit 2 and the portable unit 2 are carried on condition that the special number operation or the like is performed in step S5 on the condition that the special number operation or the like is performed on the operation P2. A line via wireless communication with the telephone 40 has been formed, but as an operation state to be realized instead, it is off-hook within a predetermined time limit range (for example, within a few seconds after the ringing of the mobile phone ringing in Step S2). Is a condition. In this case, the control subject relating to time measurement (the main control unit 15 of the main device 1, the child device control unit 23 of the child device 2, or the control unit 49 of the mobile phone 40) includes a timer and counts the time condition. The control subject relating to the judgment (which may be the same as the control subject relating to the case measurement) determines whether or not the off-hook timing satisfies the time condition.

  In this modified example, a determination unit is configured to determine whether or not the control subject relating to the determination is in an off-hook state within a predetermined time range. Then, when this determination is satisfied, it is determined that a line via wireless communication between the handset 2 and the mobile phone 40 is formed on condition that a special number operation or the like is performed as in step S5. This corresponds to a second call control means for controlling the availability of a response call according to the determination result.

  In this modification, for example, by setting the time limit range relatively short, if a full-time user is present at a desk where the handset 2 is present, it is possible to quickly go off-hook within the time range. In this case, the answering call is possible, and if the full-time user is vacant, the answering call cannot be made because it is already out of the above time range when the third party goes off-hook to answer. As a result, similar to the above embodiment, it is possible to prevent a third party from responding, and to ensure necessary privacy and improve usability.

(4) Automatically recognizing that the user is a full-time user, that is, the normal ringing is not performed in step S2 instead of the normal ringing tone, and the operation of the special number or the operation within the time limit is also performed in the operation P2. However, the handset 2 directly recognizes that the person who is going to answer the call is a full-time user, and wireless communication between the handset 2 and the mobile phone 40 in step S5 is performed on the condition. In this case, a line is formed through the network.

  In this case, as an identification means for identifying that the user is a full-time user, a method for identifying a fingerprint obtained through a known fingerprint sensor by comparing it with a fingerprint of a full-time user registered in advance, an image obtained by a camera, etc. A method of identifying by comparing with a part of the body of a dedicated user registered in advance (face, figure of the whole body, etc.), a method of identifying a voice acquired by a microphone etc. by comparing with a voice of a dedicated user registered in advance ( In this case, if it is determined that the user is not a full-time user by identifying with the first voice after being off-hooked, the subsequent call may not be continued). These fingerprints, facial images, real voices, and the like constitute characteristic information included in specific persons described in each claim, and a fingerprint sensor, a camera, a microphone, and the like constitute characteristic information detection means for detecting the characteristic information.

  In addition, as a means for indirectly identifying a full-time user, identification information (ID number, etc.) indicating that the full-time user is stored in a contact / non-contact type storage means possessed by the full-time user is read. You may make it identify. Specifically, for example, a method of reading a known wireless tag, IC card, barcode or the like by an identification information detecting means such as a scanner or a reader can be considered.

  According to the identification of the full-time user, in step S5, a line is formed through wireless communication between the handset 2 and the mobile phone 40 on condition of a special number operation or the like. This corresponds to the third call control means for controlling the availability of the answering call according to the identification result of the means.

  According to this modification, a third party is formed in the same manner as in the above embodiment by forming a line between the handset 2 and the mobile phone 40 via wireless communication in step S5 only after being identified as a full-time user. Can be prevented, and necessary privacy can be secured to improve usability.

  The automatic recognition and the above-mentioned special number operation and the time limit described in (3) above may be combined to enable answering calls. Alternatively, the automatic recognition and the above-mentioned limited notification to the full-time user may be combined. Also good. Furthermore, all of these, that is, limited notifications to full-time users, automatic recognition of full-time users who want to respond by receiving notifications, and only when the full-time user performs special number operation or off-hook within the time, etc. It may be possible.

(5) Applying to a transmission / reception system other than a button telephone As described above, the transmission / reception system of the present invention includes a main apparatus 1 and a button telephone system including a plurality of slave units 2 connected to the main apparatus 1 via a wired communication line. However, the present invention may be applied to other transmission / reception systems. A home telephone system comprising a wired telephone connected to a wired communication line (so-called home phone master unit) and a wireless telephone connected to the present invention via wireless communication (so-called home phone slave unit) 3 and 4 will be described by taking the case of applying to the above as an example.

  FIG. 3 is a functional block diagram showing the overall configuration of the transmission / reception system (home telephone system) of the present modification, and corresponds to FIG. 1 described above. Components equivalent to those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  In FIG. 3, this home telephone system is capable of answering a call with the master unit 2 'as a non-mobile-side transmitter / receiver connected to the telephone line 11 and when the incoming call is received, the master unit 2' responds to the incoming call. And a wireless handset 40 'as a portable handset that is associated via wireless communication (one-to-one in this example).

  The base unit 2 'includes an external line interface unit 12 equivalent to the main device 1 of the above embodiment, a communication circuit 22, a control unit 23, an operation input unit 24, a display unit 25, a memory 26, and a wireless unit equivalent to the slave unit 2. And an interface unit 32.

  The communication circuit 22 decodes the audio data received by the external line interface unit 12 into an audio signal and outputs the audio signal from a handset or a speaker (not shown), encodes the audio input from the handset into audio data, and outputs the external line interface. To the unit 12. The wireless interface unit 32 performs data communication with the slave unit 40 'that is paired by wireless communication via the antenna 32A.

  In addition to the above, the parent device 2 ′ has a power feeding unit 37 that supplies electric power for charging a battery 43 (described later) of the child device 40 ′ electrically connected via the charging terminal 37 </ b> A.

  On the other hand, the wireless slave device 40 ′ is equivalent to the mobile phone 40 of the above embodiment, and includes a wireless interface unit 41, a voice processing unit 42, a battery 43, a charging unit 44, a storage unit 46, and a display unit 47. , A key input unit 48 and a control unit 49.

  The interface unit 41 performs data communication with the corresponding parent device 2 ′ by wireless communication via the antenna 41 </ b> A. Charging unit 44 charges battery 43 with the power supplied from charging terminal 37A of base unit 2 ′ via charging terminal 44A.

  FIG. 4 is an operation flow showing a control operation executed by the cooperation of the control unit 23 and the child device 40 ′ of the parent device 2 ′, and corresponds to the above-described FIG. The same steps as those in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  In FIG. 4, first, when there is an external incoming call to the slave unit 40 ', an incoming notification signal indicating that is sent from the slave unit 40' to the master unit 2 '(step S1), and the master unit 2' responds accordingly. An incoming call sound indicating that there has been an incoming call is generated in the slave unit 40 '(step S2).

  Similar to FIG. 2, this ringing tone is different from the ringing tone at the time of incoming call at the normal base unit 2 '(via a wired telephone line), and at least a dedicated user of the secondary unit 40'. It is assumed that the user can easily understand that the call has arrived at the child device 40 '.

  Thereafter, base unit 2 'is set in an off-hook state in response to the incoming call ringing (operation P1). At this time, in the case where there is such a slave unit ringing in the master unit 2 ', as in FIG. 2, a preset specific operation (special number operation or special key operation) must be performed. Conditions are set so that incoming call answering calls cannot be made to the slave unit 40 '. When the special number operation or the like corresponding to this setting is performed (operation P2), the above conditions are satisfied, and a line is formed through wireless communication between the parent device 2 'and the child device 40' (step S5). The other party can make a response call from the master unit 2 'via the slave unit 40'.

  Thereafter, when the answering call is finished and the base unit 2 'is in an on-hook state (operation P3), wireless communication from the base unit 2' to the handset 40 'is interrupted (step S6), and the handset 40' is in the end state. It becomes.

  In the operation flow described above, the control signal may be generated in any way by the control unit 23 of the master unit 2 'and the control unit 49 of the slave unit 40'. As long as the above operation is realized as a result, it is sufficient.

  Also in this modified example, the third party (a person other than the full-time user of the slave unit 40 ′) did not notice that the incoming call was received by the slave unit 40 ′, as in the above embodiment, and further noticed. However, since a response cannot be made unless a specific operation is executed, it is possible to prevent a third party other than the full-time user of the slave unit 40 'from responding to an incoming call inadvertently. As a result, necessary privacy can be ensured and usability can be improved.

  Further, the present invention provides a portable telephone set and a telephone system other than the home telephone system as long as it is a transmission / reception system including a portable transmission / reception apparatus and a non-portable transmission / reception apparatus linked to the portable telephone transmission system.
