In addition, the caller (caller) may have been waiting indefinitely without knowing whether or not there is a person making the call. A tag is provided on the shoe sole, a reader is provided on a floor mat in a plurality of rooms, and a user wearing the shoe walks on the floor mat to monitor the user's location, and a phone near the location A technique for transferring a telephone is disclosed in Patent Document 1.
Japanese Patent Laid-Open No. 6-139490

However, with the technique described in Patent Document 1, the configuration of the user location monitoring system is extremely large.
The present invention has been made in view of the above circumstances, and its purpose is to determine whether or not there is a person to be called (a person who should make a call) near the telephone itself when an incoming call is received. The purpose is to enable confirmation with a simple configuration.

The telephone system of the invention of claim 1 is a telephone system comprising a plurality of telephones and a tag carried by a person to be called, the plurality of telephones including a first telephone that receives an incoming call from outside And a second telephone that can communicate with the first telephone through communication means. The first telephone includes a first reader that can communicate with the tag and the first telephone. First tag presence detection means for detecting whether or not the tag is present in the vicinity of the telephone by causing the first reader to communicate with the tag when an incoming call is received; Tag presence inquiry means for transmitting a tag presence inquiry to the second telephone via the communication means when the tag presence detection result by the tag presence detection means is nonexistent, and tag presence returned by the second telephone Perform processing according to the detection result Response result processing means is provided, and the second telephone has a second reader capable of communicating with the tag, and the second reader receives the tag existence inquiry from the first telephone. A second tag presence detecting means for detecting whether or not the tag is present in the vicinity of the second telephone by executing communication with the tag, and a tag presence detection result by the second tag presence detecting means The present invention is characterized in that response control means for responding to the first telephone through the communication means is provided.

In the telephone system according to the first aspect of the present invention, when an incoming call is made to the first telephone, the first tag presence detecting means of the first telephone communicates with the tag carried by the person to be called by the reader. To detect whether the tag exists in the vicinity. Thereby, it is possible to detect whether or not the person to be called is in the vicinity of the first telephone itself without using a large-scale configuration. When the first telephone itself does not detect the person to be called (when it does not exist), the tag inquiry means causes the second telephone to make a tag presence inquiry.

  Then, when the second telephone receives the tag presence arrangement, the second tag presence detection means of the telephone detects whether the tag exists in the vicinity, that is, whether the person to be called exists. Accordingly, when it is detected that there is no person to be called on the first telephone, the second telephone detects the presence of the person to be called. Thereby, the presence detection range of the person to be called can be widened. Then, the tag presence detection result (call target person presence detection result) by the second tag presence detection means is given to the first telephone by the response control means, and the first telephone that receives this result responds to the response result. Since the processing means performs processing according to the tag presence detection result, processing according to the presence / absence of the presence of the person to be called can be performed.

In this case, the processing performed by the response control means is performed by notifying the caller that there is no communication target when the tag presence detection result by the second tag presence detection means is not present, When the tag presence detection result by the detection means is present, the caller may be notified of the presence of the person to be called (invention of claim 2 ). This is convenient because it is possible to notify the caller (caller) who has called the first telephone about the presence or absence of the person to be called.

Further, it may be configured to include first presence handling processing means for performing processing according to the presence when the tag presence detection result by the first tag presence detection means is present ( claim 3) . (Invention) In this way, various processes according to the presence of a person to be called on the first telephone are possible. In this case, the processing performed by the first presence handling processing means may be processing for continuing the incoming call to the first telephone (invention of claim 4 ). It is possible to urge the person to be called who is near the first telephone to answer the call by continuing the incoming call.

Also in this case, the first tag presence detection means causes the first reader to perform communication with the tag on the condition that no call starts for a predetermined time after an incoming call is received. May be detected in the vicinity of the first telephone (invention of claim 5 ).

Further, a plurality of second telephone, the tag presence inquiry means of the first telephone, the tag presence inquiry to the plurality of second telephone may be performed according to the preset priority (claim 6 invention). In this way, for example, if the priority is set so that the person to be called takes a call frequently, and there is no person to be called in the vicinity of the first telephone, Tag inquiries can be made in descending order of probability of receiving a call.

Also, a plurality of second telephones are provided, and a tag is provided so that a plurality of persons to be called carry, and tag presence inquiry means in the first telephone is set with a priority for the plurality of tags, In addition, for each of the plurality of tags, the priority order of the tag presence inquiry is set for the plurality of second telephones, and the priority order of the corresponding second telephone is set in order of the tag presence inquiry from the highest priority tag. (Invention of claim 7 ). In this way, tag inquiries can be made in consideration of a call subject with a high priority and a second telephone with a high priority. For example, in the case where the first telephone is almost exclusively for a specific call target and another call target also uses the first telephone, and the specific call target for a plurality of second telephones. When there is a different probability of answering a call, when it is detected that there is no person to be called on the first telephone, a tag inquiry from the first telephone to the second telephone is made. The tag carried by the user (assuming that the priority is first) is set separately for the tag (priority is second) that is carried by the second telephone with the highest priority and then carried by another person to be called. It is also possible to perform the call from the second telephone with the higher priority, and when there is no person to be called near the first telephone, Efficient for the second phone It is possible to knowledge.

First, a first reference example will be described with reference to FIGS. FIG. 1 shows a telephone system 3 in the case of one telephone 1 and one tag 2. As shown in FIG. 2, the telephone 1 is composed of a mobile phone, for example. The tag 2 is carried by the person to be called M and is incorporated in the name tag 4. In the present invention, an IC card capable of non-contact communication with a reader is also included in the tag.

  The telephone 1 includes a telephone unit 5 and a reader 6. The telephone unit 5 includes a telephone control unit 5a, a storage unit 5b, and a telephone radio unit 5c. The telephone control unit 5a includes a CPU, a ROM, and a RAM. When a call is received from the caller to the telephone radio unit 5c via the telephone base station, a notification unit (sound output unit, (Including display means or a vibrator) and a notification operation (calling process), and the reader 6 is controlled. The telephone control unit 5a corresponds to a tag presence detection unit, a non-existence handling processing unit, and a presence handling processing unit. The storage unit 5b stores various data such as personal phone numbers and unique ID information.

  The reader 6 includes a reader control unit 6a and a reader communication unit 6b. The reader 6 performs contactless communication with the tag 2 and reads the unique ID of the tag 2. The tag 2 includes a tag control unit 2a and a tag communication unit 2b. The tag 2 is composed of an RFID tag and has a unique ID. When there is an inquiry communication (communication signal and power supply signal communication) from the reader 6, the tag 2 generates power and operates. ID information is returned.

  Now, the control contents of the telephone control unit 5a (including functions as a tag presence detection unit, a presence / absence handling processing unit, and a presence / absence handling processing unit) will be described with reference to the flowchart of FIG. This flowchart starts when an incoming call is received by the telephone 1. When there is an incoming call, the above-described calling process is executed (step P1), and if there is a call start trigger such that the call target person M turns on the call start button (“YES” in step P2), the caller (phone) The party who made the call is connected to perform a call control (step P3). As is well known, this call control is terminated when the telephone 1 or the caller performs a call stop operation (call stop button is turned on or a handset is placed).

  When a predetermined time elapses without a call start trigger in step P2 (“YES” in step P4), the reader 6 is caused to communicate with the tag 2 to detect whether the tag 2 exists in the vicinity ( Tag presence detection means). If the tag 2 is not in the vicinity of the telephone 1 at step P6 (when there is no response from the tag 2), the non-existence handling process (step P7) corresponding to the absence of the tag is executed. In this case, the caller is notified through the telephone base station that there is no person to be called.

  Further, in the tag presence detection in step P5 described above, if communication with the tag 2 is confirmed and the unique ID is authenticated, it is determined in step P6 that there is a tag (“YES” in step P6). Then, the presence corresponding process corresponding to the presence of the tag is executed in step P8. In this case, the caller is notified that there is a person to be called. Thereafter, when there is a call start trigger (step P9), call control is performed (step P10).

Thus, according to the first reference example , when an incoming call is made to the telephone 1, the telephone control unit 5a in the telephone 1 causes the reader 6 to communicate with the tag 2 carried by the person to be called. , It is detected whether the tag 2 exists in the vicinity. Thus, the telephone 1 itself can detect whether or not the person to be called is in the vicinity of the telephone 1 itself without using a large-scale configuration. Then, when the tag presence detection result indicates that there is no presence, the corresponding processing corresponding to the absence is performed, so that it is possible to perform processing according to the fact that the person to be called is not in the vicinity of the telephone 1 itself.

In this case, according to the first reference example , since the presence absence process is a process of notifying the caller that there is no call target person, the call target person is not in the vicinity of the telephone 1 itself. This is convenient because it can be notified to the caller.

Further, in the first reference example , when the tag presence detection result is present, the process corresponding to the presence is performed, so various processes according to the presence of the person to be called are possible. It becomes. In this case, the presence corresponding process is a process of notifying the caller of the presence of the person to be called, so it is convenient to notify the caller that there is a person to be called.

Further, according to the first reference example , after the incoming call is received, the reader 6 is caused to execute communication with the tag 2 on the condition that there is no call start trigger (call start) for a predetermined time or more. Since it is detected whether or not the tag 2 is present in the vicinity, the detection operation of the tag presence detection means can be started at a necessary time.

FIG. 4 shows a second reference example , and the following two points are different from the first reference example . First, after the calling process (step Q1), tag detection is immediately started (step Q2), and the presence of tag 2 is not detected even after a predetermined time has passed (steps Q3 and Q4). Is that the non-existence handling process (step Q5) is performed. Thereby, when the person to be called is in the vicinity of the telephone 1, the presence handling process can be immediately executed. The second point is present even when presence / absence is determined and presence / absence handling processing is performed (steps Q3 and Q6), but there is no call start trigger after waiting for a predetermined time (steps Q7 and Q8). The absence handling process (step Q9) is performed. This makes it possible to notify the caller of the absence by the presence / absence handling process in step Q9 when the person to be called is not available even if the person is nearby, which is convenient.

Then 5 to 8 show a third reference example, the telephone system 11 of the third reference example, in addition to the phone 1 and the tag 2 in the first reference example, another phone 12 The telephone 12 does not include a reader. In the third reference example , the control content (see FIG. 7) of the telephone 1 is different from the control content (see FIG. 3) in the first reference example in step P7 ′. That is, in the first reference example, the presence without the tag 2 is detected, but there was performs the OOO to the calling source as without the presence corresponding process, in the third reference example, the telephone 1 The other telephone set 12 is registered in advance as a transfer destination, and the incoming call is transferred to the other telephone set 12. Then, as shown in FIG. 8, the other telephone 12 performs a call process when there is a transfer (step R1), and if there is a call start trigger during a predetermined time (step R2, step R3). ), Call control is executed (step R5), and if there is no call start trigger, absence processing (step R4) is executed. In the absence process, for example, the caller is notified of the absence of the call target. According to the third reference example , when the telephone 1 detects that there is no person to be called, it is convenient to transfer the incoming call to another telephone 12.

FIG. 9 shows a first embodiment of the present invention, and the telephone system 21 shown in the first embodiment includes a first telephone set 22, a second telephone set 23, and a tag 2. .

First, when there is an incoming call from the other telephone (not shown) to the first telephone set 22, a calling process is executed as shown in FIG. 11 (step S 1), and if there is a call start trigger (“YES” in step S 2). Then, a call is connected to the caller (calling side) to control the call (step S3).

  If a predetermined time elapses without a call start trigger in step S2 ("YES" in step S4), the first reader 25 communicates with the tag 2 in step S5, and the tag 2 exists in the vicinity. Is detected (first tag presence detection means). If the tag 2 is not in the vicinity of the telephone 1 at step S6 (when there is no response from the tag 2), a tag presence inquiry is transmitted to the second telephone 23 at step S7 (tag presence inquiry means). In step S8, a response from the second telephone 23 is awaited.

  Here, if the second telephone set 23 has the above-mentioned tag assembling from the first telephone set 22 side, the second telephone set 23 in step T3 (there is no presence) in the flowchart of FIG. 12 (details will be described later). Notification) or step T4 (notification of presence) is returned.

  When there is this response (determined in step S8), based on the response result (determined in step S9), the response result corresponding process is executed in steps S10 and S11 (response result corresponding processing means). In this response result handling process, when the response result from the second telephone 23 has a tag, the incoming call is transferred to the second telephone 23 in step S10. When there is no tag, an appropriate response is made in step S11. Perform absence processing.

  If it is determined in step S6 that there is a tag, the incoming call is continued. In this case, the calling process is continued (first presence / absence handling processing means) (step S12), and if there is a call start trigger (step S13). Then, the above-described call control is performed (step S3).

  When a tag presence inquiry is transmitted to the second telephone 23 in step S7, the second telephone 23 receives the inquiry and the telephone control unit 26a executes the flowchart of FIG. In step T1, the second reader 27 communicates with the tag 2 to detect whether the tag 2 exists in the vicinity (second tag presence detection means). When the tag 2 is not in the vicinity of the telephone 1 at step T2 (when there is no response from the tag 2), the tag presence detection result is returned to the first telephone 22 at step T3 (response control means). When the tag 2 is in the vicinity of the telephone 1, the tag presence detection result is returned to the first telephone 22 in step T4 (response control means).

  After this step T4, it waits for the transfer of the incoming call from the first telephone 22 (step S10 in FIG. 11) in step T5. If there is a transfer, the call processing is performed (step T6), and there is a call start trigger. (Step T7), call control is performed (Step T8).

According to the first embodiment , when an incoming call is made to the first telephone set 22, it is detected whether or not the tag 2 exists in the vicinity of the first telephone set 22. Thereby, it is possible to detect whether or not the person to be called is in the vicinity of the first telephone 22 itself without using a large-scale configuration. When the first telephone set 22 detects that there is no call target person, the second telephone set 23 detects the presence of the call target person. it can. Further, the tag presence detection result (call target person presence detection result) at the second telephone 23 is given to the first telephone 22, and the first telephone 22 that receives this result receives the tag presence detection result. Since the corresponding processing is performed, it is possible to perform processing according to the presence or absence of the person to be called.

  In this case, as the tag presence handling process, the incoming call to the first telephone 22 is continued (calling process is continued). It is possible to prompt the user to answer the call by continuing the incoming call.

In the first embodiment , in step T3, which is a response control process, the caller is notified of the absence of the person to be called as a response content, and in step T4, which is also a response control process, the response content is issued. The caller may be notified that there is a person to be called. This is convenient because the caller (caller) calling the first telephone 22 can be notified of the presence or absence of the person to be called by the second telephone 23.

FIGS. 13 to 18 show a second embodiment of the present invention. In the second embodiment , the first embodiment is that the telephone system 31 includes a plurality of second telephones and a plurality of tags . This is different from the embodiment . In this telephone system 31, a plurality of second telephones 23A and a second telephone 23B in this case are provided for the first telephone 22, and tags 2A and 2B are provided as tags.
