When provided with a, which are connected to each other via a bus 60.

  Next, an operation example at the time of incoming call in the communication apparatus 1 will be described with reference to the sequence diagram of FIG. When the caller makes a call, the telephone line 100 is inverted in polarity, and then a CAR signal, which is an activation signal in the ND service, is transmitted from the line side (switch), the master unit 2 detects the polarity inversion, and The CAR signal is detected. When the base unit 2 detects the CAR signal, the base unit 2 checks from the ID table stored in the ROM 22 whether or not there is a fax unit that can acquire the transmission number information and the like. Specify and send a caller ID information acquisition request.

  FIG. 4A shows an example of the ID table. As shown in FIG. 4A, in the ID table, the FAX slave unit 3 and the cordless slave unit 4 constituting the communication device 1 are registered, and each slave unit has its own terminal ID, Information indicating whether or not transmission number information or the like can be acquired is registered. Since the communication apparatus 1 of this example has one FAX slave unit 3 and three cordless slave units 4 (cordless slave units A, B, and C), the terminal ID and the transmission for each one of these. Information about whether or not to obtain number information is registered. With regard to the transmission number information and the like acquisition possibility information, it is registered that only the FAX slave unit 3 is “permitted” (that is, acquisition is possible).

  Therefore, in this example, after detecting the CAR signal from the line side, the master unit 2 refers to this ID table, confirms that the FAX slave unit 3 can acquire the transmission number information, etc. 3 (that is, the terminal ID of the FAX slave device 3 is used as a transmission destination), and a request for obtaining transmission number information and the like is transmitted wirelessly.

  When the FAX slave unit 3 receives the transmission number information acquisition request from the master unit 2, the FAX slave unit 3 returns a response to the transmission number information acquisition request to the master unit 2 (wireless transmission). . By receiving the transmission number information acquisition request, the FAX handset 3 can recognize that the transmission number information will be transmitted from the line side soon, and can prepare for reception of the transmission number information. Thereafter, a voice communication connection is performed between the master unit 2 and the FAX slave unit 3 to enable real-time communication of voice signals between the two. Then, base unit 2 performs line closing (so-called primary closing).

  The closing of the line by the master unit 2 is recognized as a response signal to the CAR signal on the line side (exchange), and thereby, transmission number information and the like are transmitted from the line side (specifically, a voice including the transmission number information and the like) Signal is sent). The voice signal is received by the FAX slave unit 3 via the master unit 2, and the transmission number information and the like are acquired by the FAX slave unit 3.

  When the FAX handset 3 receives (acquires) the transmission number information or the like, the FAX handset 3 transmits a voice communication disconnection request to the base unit 2, and the base unit 2 returns a response to the FAX handset 3. Thereby, the voice communication between the main | base station 2 and the FAX subunit | mobile_unit 3 is cut | disconnected, and the real-time communication of an audio | voice signal is stopped. After the voice communication is disconnected, the FAX slave unit 3 wirelessly transmits the transmission number information and the like to the master unit 2.

  When the base unit 2 receives the transmission number information from the FAX slave unit, the base unit 2 checks the control method set for the caller telephone number included in the transmission number information from the telephone directory table. FIG. 4B shows an example of the phone book table. As shown in FIG. 4B, a plurality of telephone numbers (counter telephone numbers) are registered in the telephone book table by an input operation by the user. For each telephone number, the name of the party having the telephone number and a control method to be performed when an incoming call is received from the telephone number are registered. As a control method, in this example, call target child device information indicating which cordless child device is called and ringing sound designation information for designating a ringing sound when the cordless child device 4 is ringed are registered.

  For example, when there is an incoming call from a partner whose phone number is 090-xxxx-xxxx, when the master unit 2 acquires the phone number based on the transmission number information from the FAX slave unit 3, the master unit 2 Refer to the table and confirm that the phone number is registered. And the other party name and control method which are registered with respect to the telephone number are confirmed. In this case, the partner name is “Mr. XX”, the cordless handset information in the control method is “cordless cordless handset A”, and the ringing tone designation information is “melody a”. Therefore, the base unit 2 transmits a transmission number and the like for the cordless handset A among the three cordless handset 4 (cordless handset A, B, C).

  Specifically, information that adds the partner name and ringing tone designation information to the caller's telephone number and also the terminal ID of the cordless cordless handset A to be called (see FIG. 4A) is wirelessly added. To send.

  The transmitted information is received by each slave unit, but each slave unit determines whether or not the terminal ID of the call target indicates itself, and if it does not indicate itself, The received information is discarded. On the other hand, when the terminal ID of the call target indicates itself, the received information is acquired, and when the call is received from the base unit 2 later, the caller telephone number and the other party name are displayed on the display unit 58. At the same time, the speaker 61 is caused to ring with the specified ringing sound. At that time, in the above example, only in the cordless handset A, the telephone number (090-xxxx-xxxx) and the name of the other party (Mr. XX) are displayed on the display unit 58, and the ringing sound of the melody a is transmitted from the speaker 61. Will be output.

  On the other hand, for the telephone number of 090-abcd-xxxx, the fact that the incoming call is rejected is set in the telephone book table. Therefore, when there is an incoming call from the other party with the phone number of 090-abcd-xxxx, the base unit 2 confirms that the number is a call rejection target number in the phone book table and rejects the incoming call. Specifically, neither of the cordless cordless handsets 4 is transmitted and the calling number is not transmitted. In addition, a message indicating that the incoming call is rejected is sent to the caller side. Various specific processing methods for rejecting an incoming call are conceivable. For example, the line may be simply disconnected.

  The master unit 2 confirms the control method by referring to the telephone directory table based on the transmission number information from the FAX slave unit 3 and processes according to the control method (transmission of the transmission number or the like to the cordless slave unit 4 or If the incoming call is rejected, the line is released. This line release is recognized as a signal indicating completion of reception of the transmission number information and the like on the line side (exchange). In response to the line opening, a Ring signal (calling signal) is transmitted from the line side.

  When the base unit 2 detects a Ring signal from the line, the base unit 2 performs a call by designating a cordless slave unit to be called. As a result, in the cordless cordless handset to be called, the display unit 58 displays the caller telephone number and the name of the other party, and the specified ringing sound is generated.

  For example, when there is an incoming call from the other party whose telephone number is 052-zzzz-zzzz, when the base unit 2 acquires the telephone number based on the transmission number information from the FAX handset 3, all cordless sub units In the machine 4, the telephone number and the name of the other party (Mr. ΔΔ) are displayed on the display unit 58, and a standard ringing sound (for example, a general bell sound) is output from the speaker 61.

  In the cordless cordless handset 4 that has received a call from the base unit 2 and displayed and ringing the calling number, the user then performs a call start operation such as off-hook. Then, the cordless handset 4 transmits a voice communication connection request to the base unit 2. As a result, a voice communication connection is established between the cordless slave unit 4 and the master unit 2, and real-time relay / transmission / reception of voice signals via the master unit 2 is possible between the line side and the cordless slave unit 4 It becomes. Then, base unit 2 performs line closing (so-called secondary closing).

By closing the line, the polarity is reversed on the line side, and then the voice call is started and the call is in progress. Thereafter, when the voice call by the user is finished and a predetermined call end operation (for example, on-hook) is performed in the cordless handset 4, the cordless handset 4 transmits a voice communication disconnection request to the base unit 2. As a result, the voice communication between the parent device 2 and the FAX slave device 3 is disconnected, and then the parent device 2 releases the line, whereby the processing related to the voice call in the communication device 1 ends.

  Next, processing executed by each of the master unit 2, the FAX slave unit 3, and the cordless slave unit 4 in order to realize the above-described operation at the time of incoming call will be described with reference to the flowcharts of FIGS.

  First, the base unit incoming call control process executed by the control unit 21 of the base unit 2 will be described with reference to FIG. When the polarity inversion of the telephone line 100 is detected by the incoming call and the CAR signal is subsequently detected, the control unit 21 of the parent machine 2 starts the parent machine incoming call control process shown in FIG. In FIG. 5, the content (polarity inversion / CAR signal detection) indicated by the wavy frame before S110 is a condition for starting the master incoming control process of FIG. 5 (a condition for triggering the process start). It is shown for convenience.

  When the control unit 21 starts this master unit incoming control process by polarity reversal and CAR signal detection, first, in S110, the registration of the FAX slave unit from the ID table (see FIG. 4A) stored in the ROM 22 is performed. Check for presence. In S120, based on the confirmation result, it is determined whether or not a FAX slave device capable of acquiring transmission number information or the like is registered. Here, if the FAX slave unit that can acquire the transmission number information or the like is not registered in the ID table, the process proceeds to the call connection relay processing of S280, but the FAX slave unit that can acquire the transmission number information or the like is registered. If yes, the process proceeds to S130.

  In S130, a transmission number information acquisition request is transmitted with the terminal ID of the FAX slave that can acquire the transmission number information as a transmission destination. After transmitting the transmission number information acquisition request, it is determined in S140 whether there is a response from the FAX slave unit. At this time, even if there is no response immediately from the FAX slave unit, the response is waited until a predetermined time (for example, 6 seconds) elapses from the detection of the CAR signal (S150). If no response is received from the FAX slave unit even after a predetermined time has elapsed since the detection of the CAR signal, the process proceeds to S280. On the other hand, if there is a response from the FAX slave unit before the predetermined time has elapsed since the CAR signal was detected, the process proceeds from S140 to S160, where voice communication is connected to the FAX slave unit, and the line is closed in S170. Perform tying (primary closing).

  After the line is closed in S170, it is determined in S180 whether a voice communication disconnection request has been received from the FAX slave unit. At this time, even if the voice communication disconnection request is not immediately received from the FAX slave unit, the voice communication disconnection request is waited until a predetermined time (for example, 7 seconds) elapses after the line is closed in S170 (S190). If there is no voice communication disconnection request from the FAX slave unit even after a predetermined time has elapsed since the line was closed, the control unit 21 of the master unit 2 disconnects the voice communication with the FAX slave unit in S200, The process proceeds to S270. On the other hand, if a voice communication disconnection request is received from the FAX slave unit before a predetermined time has elapsed since the line is closed in S170, the process proceeds from S180 to S210, a response is returned to the FAX slave unit, and the fax slave unit is subsequently returned in S220. Disconnect voice communication.

  After the voice communication is disconnected in S220, it is determined in S230 whether the transmission number information or the like has been received from the FAX slave unit. At this time, even if the transmission number information or the like is not immediately received from the FAX slave unit, the transmission number information or the like is waited until a predetermined time (for example, 7 seconds) elapses after the line is closed in S170 (S240). If no transmission number information or the like is received from the FAX slave unit even after a predetermined time has elapsed since the line was closed, the process proceeds to S270.

On the other hand, if the transmission number information or the like is received from the FAX slave before the predetermined time has elapsed since the line is closed in S170, the process proceeds from S230 to S250, and the call is transmitted from the telephone directory table (see FIG. 4B). Check the control method corresponding to the caller telephone number included in the number information. And based on the confirmation result, a transmission number etc. are transmitted to a cordless cordless handset at S260. Specifically, as described above, the other party's name and ringing sound designation information are added to the caller's phone number,
Furthermore, information to which the terminal ID (see FIG. 4A) of the cordless cordless handset A to be called is added is transmitted wirelessly. However, as described above, when the caller's telephone number is registered as an incoming call rejection in the telephone directory table, the cordless handset is not called. After transmitting the transmission number and the like to the cordless handset, the line is released in S270, and the process proceeds to the call connection relay process in S280.

  FIG. 6 shows specific contents of the call connection relay process in S280. As shown in FIG. 6, when proceeding to the call connection relay process in S280, first, in S310, a RING signal from the line side is detected, and then in S315, the cordless slave unit is called. As described above, this call is performed by designating a cordless child device to be called based on the telephone directory table.

  After calling the cordless handset, it is determined in S320 whether a voice communication connection request has been received from the cordless handset to be called. If no voice communication connection request has been received from the cordless slave unit, it is determined in step S325 whether or not a RING signal is still received from the line side. When the RING signal is not received, the master unit incoming control process is terminated. However, while the RING signal is received, a voice communication connection request from the cordless slave unit is awaited.

  When a voice communication connection request is received from the cordless slave unit, the voice communication connection is established with the cordless slave unit in S330, and the line is closed (secondary closure) in S335. Thereby, the voice call by the cordless slave unit is started.

  Thereafter, in S340, it is determined whether a voice communication disconnection request has been received from the cordless slave unit. If no voice communication disconnection request has been received from the cordless slave unit, a disconnection request is received from the line side in S345. Judge whether or not. When a voice communication disconnection request is received from the cordless slave unit, the process proceeds from S340 to S355. If a disconnection request is received from the line side without receiving a voice communication disconnection request from the cordless handset, the process proceeds from S345 to S350, a disconnection request is transmitted to the cordless handset, and the process proceeds to S355. When the process proceeds to S355, the voice communication with the cordless slave unit is disconnected, the line is opened in the subsequent S360, and the master unit incoming control process is terminated.

  Next, facsimile slave unit communication processing executed by the control unit 31 of the FAX slave unit 3 will be described with reference to FIG. When receiving the transmission number information acquisition request from the parent device 2, the control unit 31 of the FAX child device 3 starts the facsimile child device communication process shown in FIG. In FIG. 7, the content indicated by the wavy line before S410 (reception of the transmission number information acquisition request) is a condition for starting the facsimile slave unit communication process of FIG. 7 (a condition for triggering the process start). Is shown for convenience.

  When the facsimile slave unit communication process is started by receiving the transmission number information acquisition request from the master unit 2, the control unit 31 of the FAX slave unit 3 first sends a response to the transmission number information acquisition request in step S410. In step S420, voice communication is connected to the base unit 2, and in step S430, transmission number information and the like are received from the base unit 2. Specifically, a voice signal including transmission number information and the like is received, and transmission number information and the like are extracted from the received voice signal.

  After receiving the transmission number information and the like, a request for disconnecting voice communication is issued to the parent device 2 in S440, and a response from the parent device 2 is waited in S450. At this time, even if there is no response immediately from the base unit 2, the response is waited until a predetermined time (for example, 7 seconds) elapses from reception of the transmission number information or the like (S460). If no response is received from the base unit 2 even after a predetermined time has elapsed since the reception of the transmission number information, etc., the voice communication with the base unit 2 is disconnected in S470, and then the facsimile slave unit communication process is terminated. .

  On the other hand, if there is a response from base unit 2 before a predetermined time has elapsed since the reception of the transmission number information, etc., the process proceeds from S450 to S480, the voice communication with base unit 2 is disconnected, and in step S490, base unit 2 The transmission number information and the like are transmitted to the terminal, and the facsimile slave unit communication process is terminated.

  Next, cordless handset call connection processing executed by the control unit 51 of the cordless handset 4 will be described with reference to FIG. When the control unit 51 of the cordless handset 4 receives a calling number or the like designated as a call target from the base unit 2, it starts the cordless handset call connection process shown in FIG. In FIG. 8, the contents indicated by the wavy frame before S610 (reception of the transmission number, etc.) are convenient for the condition for starting the cordless handset call connection process of FIG. 8 (the condition for triggering the process start). This is schematically illustrated.

  When the control unit 51 of the cordless handset 4 starts this cordless handset call connection process by receiving the caller number etc. from the base unit 2, it first receives the call signal from the base unit 2 in S610, and in S620 The transmission number received from the base unit 2 is displayed. Specifically, as described above, the caller telephone number and the partner name are displayed on the display unit 58. At this time, the speaker 61 is also sounded with the designated sound.

  In step S630, it is determined whether a user has started a call start operation. Here, if the call start operation is not performed by the user, it is determined whether or not the call is still being called from the parent device 2 in S640. When the call from the master unit 2 is terminated, the cordless slave unit call connection process is terminated. However, while the call signal is received from the master unit 2, a call start operation by the user is awaited.

  Then, when the user performs a call start operation, the process proceeds from S630 to S650, where a voice communication connection request is transmitted to the master unit 2, and voice communication is connected to the master unit 2 in subsequent S660. Thereby, a voice call is started.

  After that, in S670, it is determined whether or not a call end operation has been performed by the user. If the call end operation is not performed by the user in S670, it is determined in S680 whether a voice communication disconnection request has been received from the parent device 2. While the voice communication disconnection request is not received from the parent device 2, the user waits for the call termination operation (S670), but the voice communication disconnection request is issued from the parent device 2 in S680 without performing the call termination operation by the user. If it is determined that the voice communication is received, the voice communication with the base unit 2 is disconnected at S700, and the cordless handset call connection process is terminated.

  On the other hand, if the user performs a call termination operation before receiving the voice communication disconnection request from the parent device 2, the process proceeds from S670 to S690, and the voice communication disconnection request is transmitted to the parent device 2. In step S700, the voice communication with the base unit 2 is disconnected, and the cordless handset call connection process is terminated.

  As described above, in the communication device 1 of the present embodiment, the base unit 2 itself does not have a function of directly acquiring the transmission number information from the voice signal input from the line side, and receives / receives the transmission number information and the like. The acquisition is performed by the FAX modem 37 of the FAX slave unit 3. Then, the FAX slave unit 3 acquires the transmission number information and the like from the audio signal received via the base unit 2 and wirelessly transmits the transmission number information and the like to the base unit 2.

Therefore, the base unit 2 can execute a desired process based on the transmission number information transmitted from the FAX handset 3.
In the above embodiment, various processes mainly for the cordless slave unit 4 are illustrated as desired processing based on the transmission number information acquired from the FAX slave unit 3 in the master unit 2.

  Specifically, when the base unit 2 receives the transmission number information from the FAX handset 3, the base unit 2 transmits the caller telephone number included in the transmission number information to the cordless handset 4, and the cordless handset 4 Displays the caller telephone number. By transmitting the caller telephone number to the cordless handset 4 in this way, the user of the cordless handset 4 can know the caller telephone number. In addition to the caller telephone number, the base unit 2 also transmits various information related to the caller telephone number, such as the name of the caller and ringing tone designation information, to the cordless handset 4. Therefore, the user of the cordless handset 4 can also know various information related to the caller.

  Further, the base unit 2 can designate the cordless cordless handset 4 to be called or reject the incoming call for a specific telephone number based on a control method set for each telephone number of the caller. Therefore, the communication device 1 that is convenient for the user is realized.

  Further, when receiving the CAR signal, the base unit 2 transmits a request for obtaining transmission number information and the like to the FAX slave unit 3. Thereby, the FAX slave device 3 can know in advance that the transmission number information and the like will be transmitted soon, and can prepare for the acquisition of the transmission number information and the like. Therefore, the FAX slave device 3 can reliably acquire the transmission number information and the like.

[Modification]
Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the above-described embodiment, the base unit 2 is configured to transmit a transmission number information acquisition request to the FAX slave unit 3 when receiving a CAR signal, but this transmission number information acquisition request is not necessarily required. That is, the FAX slave unit 3 is configured to extract the transmission number information and the like from the audio signal received via the base unit 2 without receiving the transmission number information acquisition request from the base unit 2. May be.

  In the above-described embodiment, when an incoming call is received, polarity inversion and CAR signal transmission are first performed on the line side. On the other hand, after the base unit 2 performs line closing (primary closing), Although the transmission number information and the like have been described as being transmitted, such a connection procedure is merely an example.

  That is, as a connection procedure at the time of incoming call, in addition to the sequence shown in FIG. 3, for example, when the transmission number information is transmitted immediately after the polarity inversion, or the direct transmission number without polarity inversion and CAR signal transmission The case where information etc. are transmitted is also considered. In addition, for example, it may be considered that the line closing (primary closing) is not performed by the master unit 2 after the CAR signal is transmitted, and the transmission number information is transmitted from the line side at a predetermined timing after the CAR signal is transmitted. When the primary closing by the parent device 2 is not performed, the line opening by the parent device 2 before the RING signal is transmitted from the line side becomes unnecessary. As described above, there are various connection procedures when an incoming call is received, but the present invention is widely applicable to such various connection procedures.

  In the above embodiment, the master unit 2 detects the CAR signal from the line side, and then transmits the transmission number information acquisition request to the FAX slave unit 3. However, this is merely an example. For example, a request for obtaining transmission number information or the like may be transmitted when polarity reversal is detected (before the CAR signal is detected).

In the above embodiment, the detection of the CAR signal from the line side is performed by the parent device 2, but this is not essential, and the parent device 2 only transfers the CAR signal to the FAX slave device 3. The FAX slave unit 3 may detect the CAR signal.

  Moreover, in the said embodiment, although the display by the display part 58 was mentioned as an example as an alerting | reporting method of the sender | caller telephone number and the other party name by the cordless cordless handset 4, this is an example to the last, for example from the speaker 61 by voice Various notification methods such as notification of a caller telephone number and a partner name can be adopted.
