Description

  The present invention relates to a telephone connected to a telephone network, a control method therefor, a telephone system, a telephone control program, and a recording medium on which the program is recorded. In particular, the present invention relates to a telephone set used in a cordless telephone system.

  Recently, with the spread of cordless telephone systems, a plurality of telephones are installed in one house. On the other hand, since a person is a moving creature, whether or not a user using the telephone is near or does not exist varies with time. For this reason, conventionally, when there is an incoming call from the outside, all the telephones notify the incoming call.

  On the other hand, there has been proposed a technique for detecting which telephone is near the user and controlling incoming notification of each telephone based on the detection result.

  For example, the telephone set described in Patent Document 1 sends a short-range detection wave to the surroundings, and when a user ID is answered, sends a registration request to the server and sends a proximity detection notification to other telephone sets. Send out via the telephone network. In addition, when the user ID is responded to the long-distance detection wave and the proximity detection notification including the responding user ID and the telephone ID of another telephone is detected, the telephone or the like is deleted in the server. Send a request. As a result, even if a responder is detected within the reach of the long-range detection wave from the own device, if the responder is within the reach of the short-range detection wave from another phone, Will not ring and ring.

  Further, in the telephone partner search device described in Patent Document 2, the responder stores an identification code unique to the person who carries it, and the interrogator reads the identification code of the responder by radio waves. The host computer stores the number of the nearest telephone of the interrogator for each interrogator, receives the identification code output from the interrogator, and associates the identification code with the number of the nearest telephone. Every time the identification code is stored, the telephone number stored in correspondence with the identification code is updated to the latest one.

  When the private branch exchange receives the identification code of the called party (the telephone partner whose location is unknown) from the calling party telephone, the private branch exchange searches the identification code of the called party with the host computer, and When the identification code is detected, the caller side telephone is connected to the telephone having the number corresponding to the identification code, and when the identification code of the called party is not detected, the caller side telephone is called. Send a signal of unknown destination. As a result, even if the nearest telephone number of a person who has moved from a predetermined position in an office building or the like is not known, the person's nearest telephone can be called.

In the parent-child telephone device described in Patent Document 3, when a call is received, the parent device searches for a wireless tag, instructs the child device to search for a wireless tag, and based on the search results of the parent device and the child device, The output volume of each unit and slave unit is set. Accordingly, even when the user is in the vicinity of the telephone device or at a remote place, the ringtone can be sounded at a volume suitable for the user.

The call detection unit 46 notifies the notification control unit 47 that the call has been detected.

  When the notification control unit 47 receives a notification from the call detection unit 46, the notification control unit 47 controls the notification unit so as to notify the call. Specifically, when receiving a notification from the call detection unit 46, the notification control unit 47 causes the speaker 32 to output a notification sound for calling. Note that the notification control unit 47 may control other notification means such as blinking light emitting means such as LEDs.

  In the present embodiment, the notification control unit 47 refers to the detection information table 40 in the storage unit 21, and when the own device detects the wireless tag 13, the notification control unit 47 receives the notification from the call detection unit 46 immediately after receiving the notification. The speaker 32 is instructed to perform the notification. On the other hand, the notification control unit 47 refers to the detection information table 40, and when the own device does not detect the wireless tag 13, the notification control unit 47 notifies the call after a predetermined period has elapsed since the notification was received from the call detection unit 46. Instruct the speaker 32 to The predetermined period can be arbitrarily set, but is preferably about 20 seconds.

  A processing operation in the telephone T having the above configuration will be described with reference to FIG. FIG. 1 shows processing operations performed by the control unit 20 of the telephone T.

  As shown in FIG. 1, first, when the call detecting unit 46 detects an internal line call (or an external line call), the notification control unit 47 refers to the detection information table 40 in the storage unit 21 and the reader / writer 33 is wirelessly connected. It is determined whether or not the tag 13 is detected (step S10 (hereinafter sometimes abbreviated as “S10”. The same applies to other steps)).

  When the wireless tag 13 is detected (YES in S10), the notification control unit 47 causes the speaker 32 to output a notification sound for calling and starts notification (S11). Next, the notification control unit 47 stands by until a call is started or a call is ended (S12). The start of the call can be determined, for example, by the user placing the handset 28 in an off-hook state or pressing a call start button on the operation unit 31. The end of the call can be determined by the radio processing unit 29 (or the incoming call detection unit 23) receiving a call end signal from the caller.

  When the start of the call or the end of the call is performed (YES in S12), the notification control unit 47 stops the output of the notification sound for calling to the speaker 32, and the notification is ended (S13). Thereafter, the processing operation by detecting the call is terminated.

  On the other hand, if the wireless tag 13 is not detected (NO in S10), it waits until a predetermined period elapses (S14), and if the call is completed during that time (YES in S15), no notification is made. The process ends. On the other hand, if the predetermined period has elapsed when the call continues (YES in S14), the process proceeds to step S11 and the above-described processing operation is performed.

  In this embodiment, the tag detection unit 45 periodically instructs the reader / writer 33 to detect the wireless tag 13. However, when the call detection unit 46 detects a call, the reader / writer 33 performs wireless communication. Detection of the tag 13 may be instructed. Furthermore, the tag detection unit 45 may send the detection result to the notification control unit 47, and the notification control unit 47 may perform the above-described notification control based on the received detection result. In this case, the time from the detection of the call to the start of the notification is slightly longer, but it is not necessary to store the detection information table 40 in the storage unit 21.

  In the present embodiment, the telephone T that detects the wireless tag 13 performs a call notification together with the telephone T that does not detect the wireless tag 13 even after the predetermined period has elapsed. The call notification may be terminated after the period has elapsed. In this case, the processing operation performed by the control unit 20 is shown in FIG.

  The processing operation shown in FIG. 7 differs from the processing operation shown in FIG. 1 in the processing operation when the wireless tag 13 is detected (YES in S10), and the other processing operations are the same. In addition, the same code | symbol is attached | subjected to the processing operation similar to the processing operation demonstrated in this embodiment, and the description is abbreviate | omitted.

  When the wireless tag 13 is detected (YES in S10), the notification control unit 47 causes the speaker 32 to output a notification sound for calling and starts notification (S16). Next, the notification control unit 47 waits until the start of the call or the end of the call is performed or until a predetermined period elapses (S17 and S18). Thereafter, the notification control unit 47 stops the output of the calling notification sound to the speaker 32 and ends the notification (S13). Thereafter, the processing operation by detecting the call is terminated.

  By the way, the telephone T that detects the wireless tag 13 is likely to have a user nearby. Therefore, when the wireless tag 13 is detected, the control unit 20 may immediately start a call when the call detection unit 46 detects an internal call (or an external line call). In this case, the notification control unit 47 desirably performs notification for about several seconds in steps S11 to S13, but does not need to perform notification. In the above case, it is desirable to use a speakerphone function that allows the user to talk without having the handset 28. In this case, user convenience is improved.

[Embodiment 2]
Next, another embodiment of the present invention will be described with reference to FIGS. In the cordless telephone system 10 shown in FIG. 1 to FIG. 7, the call destination telephone T controls the call notification timing. However, in the cordless telephone system 10 of the present embodiment, the call source telephone T is called. The timing is controlled.

  The telephone set T in the present embodiment is different from the telephone set T shown in FIGS. 1 to 7 in the configuration of the control unit 20, and the other configurations are the same. In addition, the same code | symbol is attached | subjected to the structure which has the function similar to the structure demonstrated in the said embodiment, and the description is abbreviate | omitted.

  FIG. 8 shows a schematic configuration of the control unit 20 of the telephone set T in the present embodiment. As shown in the figure, the control unit 20 includes a tag detection unit 50, a detection information transmission unit 51, a detection information acquisition unit (reception unit) 52, a call instruction acquisition unit 53, and a call control unit (calling unit) 54. is there.

  The tag detection unit 50 differs from the tag detection unit 45 shown in FIG. 6 in that the detection result acquired from the reader / writer 33 is sent to the detection information sending unit 51 instead of being stored in the storage unit 21. Other functions are the same.

  The detection information transmission unit 51 transmits detection information including the detection result received from the tag detection unit 50 to the wireless processing unit 29 and transmits it to another telephone T. In addition, the detection information transmission part 51 may transmit the said detection information periodically, and may transmit the said detection information only when the content of the detection result has changed. The detection information preferably includes a telephone ID for identifying the own device. The telephone ID may be the name of the telephone T such as “master unit”, “slave unit 1”, “slave unit 2”, and the like.

  The detection information acquisition unit 52 acquires detection information transmitted by another telephone T via the wireless processing unit 29. The detection information acquisition unit 52 stores the acquired detection information in the detection information table 40 of the storage unit 21 in association with the telephone ID of the telephone T that has transmitted the detection information.

  The call instruction acquisition unit 53 acquires instruction information for extension call by the user via the operation unit 31. The call instruction acquisition unit 53 sends the acquired extension call instruction information to the call control unit 54.

  The call control unit 54 controls calls to other telephones T. Specifically, when receiving an extension call instruction from the call instruction acquisition unit 53, the call control unit 54 transmits a call signal to each telephone T via the wireless processing unit 29.

  In the present embodiment, when the call control unit 54 receives an extension call instruction from the call instruction acquisition unit 53, the call control unit 54 refers to the detection information table 40 stored in the storage unit 21 and detects the wireless tag 13. A call signal is immediately transmitted to T. On the other hand, the call control unit 54 refers to the detection information table 40 and transmits a call signal to the telephone T that has not detected the wireless tag 13 after a predetermined period of time has elapsed after receiving the extension call instruction.

  Therefore, in the cordless telephone system 10 of the present embodiment, when calling, the calling telephone first calls a telephone that detects the wireless tag 13, and then calls a telephone that does not detect the wireless tag 13. . As a result, if a telephone that has detected the wireless tag 13 starts a call before a telephone that has not detected the wireless tag 13 performs a call notification, a telephone that does not detect the wireless tag 13 does not need to perform a call notification. . As a result, call notification can be performed efficiently.

  Next, a processing operation in the telephone T having the above-described configuration will be described with reference to FIG. FIG. 9 shows an extension call processing operation performed by the control unit 20 of the telephone T.

  As shown in FIG. 9, first, when the call control unit 54 acquires an extension call instruction, the call control unit 54 reads the detection information table 40 in the storage unit 21 (S20). Next, the call control unit 54 refers to the detection information table 40 that has been read, identifies the telephone T that is detecting the wireless tag 13, and transmits a call signal to the identified telephone T, so that the telephone T Is called (S21).

  Next, the call control unit 54 waits until the start of the call or the end of the call is performed or a predetermined period elapses (S22 and S23). When the call is started or the call is ended (YES in S22), call control unit 54 ends the processing operation according to the extension call instruction. Note that the start of the call can be determined by the radio processing unit 29 receiving a call start signal from the telephone T of the call destination. The end of the call can be determined by the user placing the handset 28 in an on-hook state or pressing a call end button on the operation unit 31.

  On the other hand, when the predetermined period has elapsed without starting the call or terminating the call (NO in S22, YES in S23), the call control unit 54 reads the detection information table 40 read from the storage unit 21. Referring to the telephone T that does not detect the wireless tag 13, the telephone T is called by transmitting a calling signal to the specified telephone T (S24).

  Then, the call control unit 54 waits until the start of the call or the end of the call (S25), and thereafter ends the processing operation according to the extension call instruction.

  In this embodiment, the telephone T that detects the wireless tag 13 makes an extension call with the telephone T that does not detect the wireless tag 13 even after the predetermined period has elapsed. The extension call may be terminated after the period has elapsed. In this case, in step S24, a call end signal may be transmitted to the telephone T that detects the wireless tag 13, and a call signal may be transmitted to the telephone T that does not detect the wireless tag 13.

  In the present embodiment, the extension call has been described, but the present invention can also be applied to the case of an external call. In this case, the parent device 11 performs the above-described calling control on the child device 12. In addition, regarding parent device 11 itself, notification control as shown in FIG. 6 may be performed instead of the call control.

[Embodiment 3]
Next, another embodiment of the present invention will be described with reference to FIGS. In the cordless telephone system 10 shown in FIG. 8 and FIG. 9, a call is made without specifying the call destination, but in the cordless telephone system 10 of this embodiment, the call destination candidates are displayed and selected by the user. By doing so, the selected call destination is called.

  The telephone set T in the present embodiment is different from the telephone set T shown in FIGS. 8 and 9 in the configuration of the control unit 20 and the storage unit 21, and the other configurations are the same. In addition, the same code | symbol is attached | subjected to the structure which has the function similar to the structure demonstrated in the said embodiment, and the description is abbreviate | omitted.

  FIG. 10 shows a schematic configuration of the control unit 20 and the storage unit 21 of the telephone set T in the present embodiment. As illustrated, the control unit 20 includes a tag detection unit 60, a detection information transmission unit 61, a detection information acquisition unit 62, an instruction information acquisition unit 63, a call destination selection unit (call destination selection means) 64, a call control unit (calling unit). Means, a call control means) 65, a call detection unit (call detection means) 66, and a notification control unit 67. The storage unit 21 stores a detection information table 70 and a user / tag correspondence table 71.

  In the user / tag correspondence table 71, the tag ID of the wireless tag 13 is associated with the user ID, which is information for identifying the user.

  In the detection information table 70, a user ID corresponding to the detected wireless tag 13 and a telephone ID of the telephone T are associated with a detection result indicating whether or not the telephone T has detected the wireless tag 13.

  The tag detection unit 60 instructs the reader / writer 33 of its own device to detect the wireless tag 13 and acquires a detection result from the reader / writer 33. Further, when the tag detection unit 60 detects the wireless tag 13, it instructs the tag ID stored in the wireless tag 13 to be read, and acquires the tag ID from the reader / writer 33.

  Further, the tag detection unit 60 refers to the user / tag correspondence table 71 of the storage unit 21 and acquires a user ID corresponding to the tag ID. The tag detection unit 60 sends the acquired detection result and user ID to the detection information sending unit 61. When the detection information table 70 includes a detection result of the own device, the tag detection unit 60 may update the detection information table 70 with the detection result and the user ID.

  The detection information sending unit 61 sends the detection information including the detection result and the user ID received from the tag detection unit 60 to the wireless processing unit 29 as compared with the detection information sending unit 51 shown in FIG. The other functions are the same except that they are transmitted to T. Instead of including the detection result and the user ID, the detection information may include a user ID when the wireless tag 13 is detected, and may include a null character string when the wireless tag 13 is not detected.

  The detection information acquisition unit 62 acquires detection information transmitted by another telephone T via the wireless processing unit 29. The detection information acquisition unit 62 stores the acquired detection information in the detection information table 70 of the storage unit 21 including the telephone ID of the transmission source telephone T. As described above, when the detection information includes a user ID or a null character string, the detection information acquisition unit 62 indicates that the wireless tag 13 is detected when the detection information includes the user ID. While creating a detection result, when a null character string is included in the detection information, a detection result indicating that the wireless tag 13 is not detected may be created.

  The instruction information acquisition unit 63 acquires instruction information from the user via the operation unit 31. The instruction information acquisition unit 63 sends the acquired instruction information to a block corresponding to the instruction information. Specifically, when the instruction information acquisition unit 63 acquires the extension call instruction information or the call destination instruction information, the instruction information acquisition unit 63 sends the acquired instruction information to the call destination selection unit 64.

  The call destination selection unit 64 allows the user to select a call destination when an extension call is instructed by the user. The call destination selection unit 64 sends information on the selected call destination to the call control unit 65.

  Specifically, when receiving the extension call instruction information from the user via the operation unit 31 and the instruction information acquisition unit 63, the call destination selection unit 64 first reads the detection information table 70 from the storage unit 21. Next, the call destination selection unit 64 creates a call destination candidate based on the detection result and the user ID included in the read detection information table 70 and causes the display unit 30 to display the created call destination candidate.

  FIGS. 11A to 11C show examples of call destination candidates displayed on the display unit 30 of the parent device 11 when the parent device 11 calls one of the four child devices 12. In the illustrated example, only the first slave unit 12 a detects the wireless tag 13.

  In the example of FIG. 11A, for each slave unit 12, the name of the slave unit 12 (slave unit 1 to slave unit 4) is displayed, and information indicating the presence or absence of detection of the wireless tag 13 is displayed in circles. Yes. In the example of FIG. 5B, only the name of the first slave unit 12a (slave unit 1) that detects the wireless tag 13 is displayed. In the example of FIG. 5C, the name of the slave unit 12 (slave unit 1 to slave unit 4) is displayed for each slave unit 12, and the first slave unit 12a detecting the wireless tag 13 is also displayed. (Slave 1) is highlighted in bold.

  Thus, by displaying the name of the slave unit 12 based on whether or not the wireless tag 13 is detected, the user who refers to the display can grasp the slave unit 12 that is detecting the wireless tag 13. . When the call destination selection unit 64 receives the instruction information of the call destination selected by the user via the operation unit 31 and the instruction information acquisition unit 63 from the user, the call destination selection unit 64 sends the selected call destination information to the call control unit To 65.

  The call control unit 65 is different from the call control unit 54 shown in FIG. 8 in that a call signal is transmitted to the call destination telephone T received from the call destination selection unit 64 via the wireless processing unit 29. Other functions are the same. Moreover, the call detection part 66 functions similarly to the call detection part 46 shown in FIG.

  When the notification control unit 67 receives a notification from the call detection unit 66 as compared with the notification control unit 47 shown in FIG. The user ID corresponding to the telephone T is acquired, and the acquired user ID and the name of the caller telephone T are displayed on the display unit 30, and the other functions are the same. As a result, the caller telephone T and the user can be grasped.

  Therefore, in the cordless telephone system 10 of this embodiment, when selecting a call destination, call destination candidates are displayed on the display unit 30 based on the detection information table 70 stored in the storage unit 21. As a result, the caller user can know whether or not the callee telephone T has detected the wireless tag 13 before the caller telephone T makes a call. Therefore, it is possible to select a call destination or whether or not to call after grasping a place where a person is estimated to exist.

  Next, a processing operation in the telephone T having the above-described configuration will be described. First, the processing operation when the wireless tag 13 is detected will be described with reference to FIGS.

  FIG. 12 shows a processing operation performed by the control unit 20 of the telephone T when the reader / writer 33 detects the wireless tag 13. As illustrated, first, the tag detection unit 60 requests a tag ID from the wireless tag 13 via the reader / writer 33 (S30).

  Next, when the tag detection unit 60 succeeds in obtaining the tag ID from the wireless tag 13 via the reader / writer 33 (YES in S31), the user tag correspondence table (device / user correspondence table) 71 The user ID corresponding to the tag ID is acquired (S32). Then, the tag detection unit 60 transmits the detection result indicating that the wireless tag 13 is detected and the user ID to the other telephone T via the detection information transmission unit 61 and the wireless processing unit 29 ( S33), the processing operation is terminated. On the other hand, if the tag detection unit 60 fails to acquire the tag ID (NO in S31), the detection result indicating that the wireless tag 13 has not been detected is sent to the detection information sending unit 61 and the wireless processing unit. 29 to the other telephone T (S34), the processing operation is terminated.

  FIG. 13 shows processing operations performed by the control unit 20 of the telephone T when data is received from another telephone T. First, the control unit 20 determines whether or not the received data includes detection information (S35). When the detection information is included (YES in S35), the detection information acquisition unit 62 updates the detection information table 70 (S36) and ends the process. On the other hand, when the detection information is not included (NO in S35), control unit 20 performs a process corresponding to the received data (S37) and ends the process.

  FIG. 14 exemplifies the flow of information in the processing operation for detecting the wireless tag 13. In the illustrated example, the first slave unit 12a detects the wireless tag 13 and transmits detection information to the master unit 11 and the second slave unit 12b. In the illustrated example, the wireless tag 13 stores a user ID together with a tag ID.

  As shown in FIG. 14, the first handset 12a periodically searches for the wireless tag 13 (S40 / S41). When the wireless tag 13 is found (S42), the user ID is detected for the wireless tag 13. Information acquisition is requested (S43). When the detection information is acquired from the wireless tag 13 (S44), the first slave unit 12a transmits data including the acquired detection information to the other units (the master unit 11 and the second slave unit 12b) (S45). Thus, when the wireless tag 13 stores the user ID, the telephone set T does not need to convert the tag ID into the user ID, and does not need to store the user / tag correspondence table 71 in the storage unit 21.

  FIG. 15 shows an example of data transmitted in step S45. In the illustrated example, the name “slave 1” of the first slave unit 12a is included in the storage area of the transmission source information, and the user name “dad” is included in the storage area of the user ID. In this way, the user ID may be a user name such as “dad”, “mother”, “Taro-kun”, or the like.

  Next, the master unit 11 and the second slave unit 12b that have received the data including the detection information update the detection information table 70 based on the acquired detection information. FIG. 16 shows an example of the updated detection information table 70. As shown in the figure, the detection information table 70 includes the name (terminal name) of the telephone T, the detection result, and the user ID for each telephone T. Further, in the illustrated example, the first slave unit (slave unit 1) 12a indicates that the wireless tag 13 corresponding to “dad” is detected.

  Next, the processing operation when the user instructs an extension call will be described with reference to FIGS. FIG. 17 shows processing operations performed by the control unit 20 of the telephone T when the user instructs an extension call through the operation unit 31.

  As shown in FIG. 17, first, when the instruction information acquisition unit 63 acquires an extension call instruction, the call destination selection unit 64 creates a call destination candidate based on the detection information table 70 in the storage unit 21 and creates the call destination candidate. The called party candidate is displayed on the display unit 30 (S50). Next, it waits until a user determines a call destination (S51). Thereafter, when the user determines the call destination and the instruction information acquisition unit 63 acquires the call destination instruction information from the user via the operation unit 31 (YES in S51), the call control unit 65 causes the radio processing unit 29 to The call destination determined by the user is called by transmitting a call signal to the call destination via (step S52).

  In step S52, when the tag ID of the wireless tag 13 corresponding to the call destination telephone T is received from another telephone T, it is desirable to change the other telephone T as the call destination. In this case, even if the user moves near another telephone T, the telephone can be called. In addition, when calling the telephone T that detects the wireless tag 13, the telephone call may be started immediately using a speakerphone or the like. In this case, a call can be performed efficiently.

  Next, the call control unit 65 waits until the start of the call or the end of the call is performed (S53). Thereafter, when the call is started or the call is ended (YES in S53), call control unit 65 ends the processing operation according to the extension call instruction.

  FIG. 18 shows a processing operation performed by the control unit 20 of the telephone T when an extension call is detected from another telephone T. As shown in the figure, first, the notification control unit 67 acquires caller information included in the call signal (S60), and whether or not the user ID corresponding to the acquired caller telephone T exists in the detection information table 70. It is determined whether or not (S61).

  When the user ID exists in the detection information table 70 (YES in S61), the notification control unit 67 notifies the display unit 30 by displaying the user ID and the name of the caller telephone T ( S62). On the other hand, when the user ID does not exist in the detection information table 70 (NO in S61), the notification control unit 67 notifies the display unit 30 by displaying only the name of the caller telephone T (S63). .

  Next, the notification control unit 67 starts other notifications such as causing the speaker 32 to output a notification sound for calling (S64), and waits until the start of the call or termination of the call is performed (S65). When the call is started or the call is ended (YES in S65), notification control unit 47 ends all notifications (S66). Thereafter, the processing operation by detecting the call is terminated. In addition, you may perform the process of step S64 before the process of step S60.

  FIG. 19 exemplifies the flow of information in the processing operation related to extension call. In the illustrated example, an extension call is made from the parent device 11 to the first child device 12a. FIG. 20 shows an example of the detection information table 70 stored in the storage unit 21. As illustrated, the base unit 11 detects the wireless tag 13 with the tag ID corresponding to “dad”, and the first handset 12a detects the wireless tag 13 with the tag ID corresponding to “Taro-kun”. On the other hand, it is assumed that the second slave unit 12b has not detected the wireless tag 13. Further, it is assumed that each telephone set T stores a detection information table 70 shown in FIG.

  As shown in FIG. 19, when the base unit 11 starts an extension call based on an instruction from the user (S70), based on the detection information table 70 shown in FIG. Is displayed (S71).

  FIG. 21 shows call destination candidates displayed on the display unit 30. As shown in the figure, each of the first handset 12a and the second handset 12b which are other telephones T of the base unit 11 is displayed as a call destination candidate. Regarding the first slave unit 12a, the name of the first slave unit 12a is displayed in the name column of the telephone T, and the first slave unit 12a is detected in the user ID column. “Taro-kun” which is the user ID corresponding to the tag ID of the wireless tag 13 is displayed. On the other hand, regarding the second slave unit 12b, since the wireless tag 13 is not detected by the second slave unit 12b, the name of the second slave unit 12b is displayed in both the name column of the telephone T and the user ID column. “Slave 2” is displayed.

  Next, when the call destination is determined according to an instruction from the user (S72), base unit 11 transmits an extension call signal to the determined call destination and transmits call destination information. On the other hand, when receiving the extension call signal and the call destination information, the first slave unit 12a notifies the extension call (S73) and displays the user ID of the call destination on the display unit 30 of the own device (S73). S74).

  FIG. 22 shows an example of a notification screen displayed on the display unit 30 of the first slave unit 12a. As shown in the figure, the notification screen includes the fact that the extension is being called and the user ID “dad” corresponding to the tag ID of the wireless tag 13 detected by the parent device 11 that is the calling source. Yes.

  In addition, in this embodiment, although user ID is transmitted, you may transmit tag ID. In this case, conversion from the tag ID to the user ID is performed at the transmission destination.
