Description

[Technical field]

[0001] The technology disclosed in this specification relates to a teleconferencing system. [Background technology]

[0002] JP 2018-174393 A discloses a telephone conference system capable of three or more parties calling. In this system, when a conference button provided on a first telephone is pressed while a first telephone and a second telephone are connected, a processing unit connects each of the first telephone and the second telephone to a conference trunk. As a result, the first telephone and the second telephone are connected to each other via the conference trunk. Thereafter, when a call operation is performed from the third telephone to the first telephone, the processing unit connects the third telephone to the conference trunk. As a result, the first telephone, the second telephone, and the third telephone are connected to each other via the conference trunk, making it possible to make a call between the three telephones (i.e., three parties). Summary of the Invention [Problem to be solved by the invention]

[0003] In JP 2018-174393 A, in order for a third party to participate in a call between a first telephone and a second telephone, it is necessary for the third party to perform a call operation. In other words, the two parties in a call cannot directly call the third party. Therefore, in the technology of JP 2018-174393 A, it is necessary to notify the third party in advance of the date and time of the conference call. For this reason, for example, convenience is low when an urgent conference call is to be held. In this specification, a technology with higher convenience is provided in a conference call system. [Means for solving the problem]

[0004] The telephone conference system disclosed in this specification includes a conference circuit configured to enable a plurality of registered telephones registered in advance to communicate with each other, a telephone exchange that stores the telephone numbers of the plurality of registered telephones and is configured to be able to connect the plurality of registered telephones to the conference circuit, and a selection device. When a call is made from an external telephone to a specific reception telephone that is connected in advance to the conference circuit, the telephone exchange is configured to connect the external telephone to the conference circuit and to connect a first registered telephone that is predetermined among the plurality of registered telephones to the conference circuit. The selection device is configured to allow a user of the first registered telephone to select a second registered telephone to be connected to the conference circuit from among the plurality of registered telephones. The telephone exchange is configured to connect the second registered telephone selected by the selection device to the conference circuit.

[0005] In the above telephone conference system, the user of the external telephone simply places a call to a designated reception telephone, and the external telephone and the first registered telephone are connected to the conference circuit, allowing a call between the two. Also, the user of the first registered telephone can select the second registered telephone as needed, and the telephone exchange connects the second registered telephone to the conference circuit. In this way, this telephone conference system is highly convenient, as it allows the caller to call a third party (i.e., the user of the second registered telephone) as needed. [Brief description of the drawings]

[Diagram 3] FIG. 4 is a diagram showing an example of a schedule table. [Figure 4] FIG. 4 is a flowchart showing a process executed by the telephone exchange. [Diagram 5] FIG. 13 is a diagram showing an example of a registered medical institution data screen. [Figure 6] FIG. 4 is a diagram showing a sequence of processes executed by each device when a conference call is held; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] In one embodiment of the present technology, the telephone conference system may further include a storage unit that stores speech contents of the user of the external telephone and the user of the first registered telephone as voice data, and a display unit. The telephone exchange may convert the stored voice data into text data and display a character string indicated by the text data on the display unit.

[0008] In this configuration, the contents of the speech of the user of the external telephone and the user of the first registered telephone are stored, so that the voice data (the contents of the speech) can be used later. Also, the voice data is converted into text data and displayed on the display unit as a character string, so that the contents of the speech can be visually confirmed.

[0009] In one embodiment of the present technology, the display unit may be configured to be viewable by a user of the second registered telephone set.

[0010] In such a configuration, the user of the second registered telephone can use the character string to understand the content of the conversation between the user of the external telephone and the user of the first registered telephone before the user of the second registered telephone joined the telephone conference.

[0011] In one embodiment of the present technology, the telephone exchange may generate the text data from the voice data stored in the storage unit by machine learning.

[0012] In such a configuration, more accurate text data can be generated by accumulating spoken content and conducting machine learning.

[0013] In one embodiment of the present technology, the external telephone may be installed in a first medical institution that accommodates a specific patient, the first registered telephone may be installed in a second medical institution to which an on-duty doctor belongs, and the second registered telephone may be installed in a third medical institution to which a specialist who can diagnose the specific patient belongs.

[0014] In this configuration, for example, when the first medical institution does not have a doctor who can examine the condition of a patient transported to the first medical institution, a conference call can be held with the second registered phone installed at the third medical institution, where a specialist doctor is located, via the doctor on duty by calling a specified reception phone. Therefore, this is particularly useful when the condition of a specific patient requires emergency care.

[0015] (Example) Hereinafter, a telephone conference system 10 (hereinafter, simply referred to as the system 10) according to an embodiment will be described with reference to the drawings. The system 10 is a system that allows a plurality of people to hold a telephone conference via a conference circuit 20. More specifically, the system 10 is a system for doctors belonging to a medical institution to hold a telephone conference with a specialist who can diagnose a patient when, for example, a child patient or a seriously ill patient is brought to the medical institution and there is no doctor who can diagnose the patient. As shown in FIG. 1, the system 10 includes a conference circuit 20, telephones 30, 40, 50, 60, 70, PCs (abbreviation of personal computer) 80, 90, 130, and a telephone exchange 100. The public network 6 is a communication network owned by a communication carrier and accommodates the telephones 30 to 70. The telephones 30 to 70 are, for example, fixed telephones, mobile phones, etc. The PCs 80, 90, 130 and the telephone exchange 100 can communicate with each other via the Internet 4.

[0016] The conference circuit 20 is configured to enable a call to be made between a plurality of telephones connected to the conference circuit 20. For example, when the registered telephones 40, 50, and 60 described later are connected to the conference circuit 20, the conference circuit 20 outputs a signal obtained by synthesizing the voice signals input from the voice input units (not shown) of the registered telephones 50 and 60 to the voice output unit (not shown) of the registered telephone 40. The conference circuit 20 also outputs a signal obtained by synthesizing the voice signals input from the voice input units of the registered telephones 40 and 60 to the voice output unit of the registered telephone 50. The conference circuit 20 also outputs a signal obtained by synthesizing the voice signals input from the voice input units of the registered telephones 40 and 50 to the voice output unit of the registered telephone 60.

[0017] Each of the registered telephones 40 to 60 is installed in a medical institution. The registered telephone 40 is installed in a medical institution A, the registered telephone 50 is installed in a medical institution B, and the registered telephone 60 is installed in a medical institution C. Although details will be described later, the telephone numbers of each of the registered telephones 40 to 60 are stored in advance in the memory 112 of the telephone exchange 100. Note that each of the registered telephones 40 to 60 may be a mobile terminal owned by a doctor belonging to each of the medical institutions A to C. Also, although three registered telephones 40 to 60 are illustrated in FIG. 1, in the system 10, telephone numbers of more than three telephones may be registered in the memory 112 of the telephone exchange 100.

[0018] The external telephone 70 is installed in a medical institution different from the medical institutions A to C. The telephone number of the external telephone 70 is not stored in the memory 112 of the telephone exchange 100. The external telephone 70 may be a mobile terminal owned by a doctor belonging to the medical institution.

[0019] The receiving telephone 30 is installed to receive calls from an external telephone 70. Although not shown, the receiving telephone 30 is configured to be connectable to the Internet 4. The telephone number of the receiving telephone 30 is made known by an administrator of the system 10 or the like via media such as the Internet or advertisements. When a call is made from an external telephone 70, the receiving telephone 30 transmits information indicating that the call has been received, together with the telephone number of the external telephone 70, to the telephone exchange 100 via a communication interface (not shown).

[0020] PCs 80, 90, 130 may be stationary devices such as a desktop PC, or portable devices such as a notebook PC or tablet PC. PC 80 is installed in medical institution A, PC 90 is installed in medical institution B, and PC 130 is installed in medical institution C. PC 80 may be a terminal owned by a doctor affiliated with medical institution A. The same applies to PCs 90, 130. PC 80 includes an operation unit 82, a display unit 84, a wireless interface 86 (hereinafter, interface will be referred to as "I / F"), and a control unit 88.

[0021] The operation unit 82 includes a plurality of keys. A user can input various instructions to the PC 80 by operating the operation unit 82. The display unit 84 is a display for displaying various information.

[0022] The wireless I / F 86 is an interface for executing Wi-Fi communication, which is wireless communication conforming to the Wi-Fi standard. The Wi-Fi standard is a wireless communication standard based on the IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.11 standard and standards equivalent thereto (e.g., 802.11a, 11b, 11g, 11n, etc.).

[0023] The control unit 88 includes a CPU, a memory (not shown), etc. The CPU executes various processes according to a program (not shown) stored in the memory.

[0024] The PCs 90 and 130 have the same configuration as the PC 80. Note that the operation unit and the like described above are not shown for the PC 130 in FIG.

[0025] The telephone exchange 100 is a device having a telephone switching function. In other words, the telephone exchange 100 interconnects telephone lines to form a telephone network. The telephone exchange 100 is also configured to be able to connect the registered telephones 40-60 and the external telephone 70 to the conference circuit 20. The telephone exchange 100 is installed, for example, by an administrator of the system 10. The telephone exchange 100 includes an office line I / F 102, a network I / F 104, and a control unit 106. The office line I / F 102 is an interface for executing communication with the public network 6. The network I / F 104 is an interface for executing communication with the Internet 4.

[0026] The control unit 106 includes a CPU 110 and a memory 112. The memory 112 is configured from a volatile memory, a non-volatile memory, etc. The CPU 110 executes various processes in accordance with a program 114 stored in the memory 112. In addition to the program 114, the memory 112 stores a registration table 116 and a schedule table 118.

[0027] As shown in FIG. 2, the registration table 116 stores medical institution information, telephone numbers, email addresses, and medical department information in association with each other. The medical institution information is information indicating the names of medical institutions (medical institutions A to C) registered in the registration table 116. The telephone numbers are telephone numbers of registered telephones 40 to 60 installed in the medical institutions A to C (or owned by doctors belonging to the medical institutions A to C) indicated by the medical institution information. The email addresses are email addresses of PCs 80, 90, and 130 installed in each of the medical institutions A to C (or owned by doctors belonging to the medical institutions A to C). The medical department information is information indicating the specialty division of doctors belonging to each of the medical institutions A to C. Specifically, for example, as shown in FIG. 2, the registration table 116 stores medical institution information "medical institution A", telephone number "052-XXX-XXXX", email address "ABC@ZZZ", and medical department information "internal medicine, surgery" in association with each other.

[0028] In the schedule table 118, as shown in Fig. 3, a calendar and on-duty doctor information are stored in association with each other. The on-duty doctor information is information indicating the medical institutions A to C (i.e., the doctor on duty for that day) in which the registered telephone that the telephone exchange 100 should connect to the conference circuit 20 is installed when a call is made from the external telephone 70 to the reception telephone 30, as described later. In other words, the on-duty doctor information is information indicating the medical institution that will be the contact point when a call is made from the external telephone 70 to the reception telephone 30. Specifically, for example, as shown in Fig. 3, the schedule table 118 stores that the medical institution A in which the registered telephone 40 is installed is the contact point on May 17, the medical institution B in which the registered telephone 50 is installed is the contact point on May 18, and the medical institution A in which the registered telephone 60 is installed is the contact point on May 19.

[0029] The memory 112 further includes an utterance content storage area 120. The utterance content storage area 120 stores, as voice data, the contents of the utterance between the external telephone 70 and a registered telephone installed at the medical institution that serves as the reception desk. In other words, the utterance content storage area 120 is an area for storing voice data input from a voice input unit (not shown) of each of the telephones 40 to 70. The CPU 110 can also convert the voice data stored in the utterance content storage area 120 into text data. The CPU 110 may generate text data from the voice data by machine learning.

[0030] Next, referring to Fig. 4, a process executed by the CPU 110 of the telephone exchange 100 when a telephone conference is held by the system 10 will be described. In the following, the description will be continued assuming that the process of Fig. 4 and Fig. 6 described later is executed on May 17 (see Fig. 3).

[0031] First, in S10, the CPU 110 judges whether or not a call has been made from the external telephone 70 to the receiving telephone 30. Specifically, when the CPU 110 receives call information indicating that a call has been made from the external telephone 70 from the receiving telephone 30 via the network I / F 104 (YES in S10), the CPU 110 proceeds to S12.

[0032] Next, in S12, the CPU 110 extracts the doctor on duty for May 17th. That is, the CPU 110 refers to the schedule table 118 and extracts medical institution A stored in association with May 17th. Then, in S14, the CPU 110 refers to the registration table 116 and extracts the telephone number "052-XXX-XXXX" of the registered telephone 40 stored in association with the medical institution A and the email address "ABC@ZZZ" of the PC 80 stored in association with the medical institution A.

[0033] In S16, the CPU 110 sends an e-mail including a viewing URL (short for Uniform Resource Locator) to the extracted e-mail address as the destination. The viewing URL is information indicating the location of the registered medical institution data in the memory 112 of the telephone exchange 100. The registered medical institution data includes medical institution information and medical department information in the registration table 116. In other words, the medical institution data does not include a telephone number or an e-mail address. When an operation to select the viewing URL displayed on the display unit 84 of the PC 80 is input, a registered medical institution data screen 122 indicating the registered medical institution data specified by the viewing URL is displayed on the display unit 84 of the PC 80 of the doctor on duty, as shown in FIG. 5. This allows the doctor on duty to know the medical institutions registered in the system 10 and their specialty classifications.

[0034] In S18, the CPU 110 connects the external telephone 70 and the registered telephone 40 to the conference circuit 20. In S14, the CPU 110 extracts the telephone number of the registered telephone 40. In addition, in S10, the CPU 110 receives the telephone number of the external telephone 70 from the receiving telephone 30 together with the call information from the external telephone 70. Therefore, based on these telephone numbers, the CPU 110 can connect the telephone line of the external telephone 70 and the telephone line of the registered telephone 40 to the conference circuit 20. This enables a call between the external telephone 70 and the registered telephone 40.

[0035] In S20, the CPU 110 stores the voice data input to the voice input units of the external telephone 70 and the registered telephone 40 in the speech content storage area 120. Here, each voice data may be stored separately so that the voice data input from the voice input units of each of the telephones 40 and 70 can be identified.

[0036] Thereafter, in S22, the CPU 110 determines whether or not connection request information has been received. The connection request information is information that requests that one of the registered telephones 50 and 60 other than the registered telephone 40 be connected to the conference circuit 20. The registered medical institution data screen 122 shown in FIG. 5 includes a plurality of connection buttons 124 corresponding to each medical institution. When the doctor on duty inputs an operation to select one of the connection buttons 124, the CPU 110 receives the connection request information via the network I / F 104.

[0037] When the CPU 110 receives the connection request information (YES in S22), in S24, it connects the registered telephone set installed in the medical institution included in the connection request information to the conference circuit 20. In the following, the explanation will be continued assuming that the connection button 124 corresponding to the medical institution B is selected. That is, in S24, the CPU 110 connects the registered telephone set 50 to the conference circuit 20.

[0038] In S26, CPU 110 converts the voice data stored in utterance content storage area 120 into text data. That is, the voice data input from external telephone 70 and registered telephone 40 is converted into text data. At this time, summary data that summarizes the generated text data may be created. Then, in S28, CPU 110 transmits the text data (or the summary data) to the email address of PC 90 installed in medical institution B as the destination, and returns to S22.

[0039] On the other hand, if the CPU 110 does not receive connection request information (NO in S22), it determines in S30 whether or not it has received call end information from any of the telephones connected to the conference circuit 20. For example, when a call end operation is executed in one telephone connected to the conference circuit 20, the CPU 110 receives the call end information from that one telephone via the network I / F 104. When the CPU 110 receives the call end information (YES in S30), it disconnects all telephones connected to the conference circuit 20 from the conference circuit 20 in S32. After executing S32, the CPU 110 ends the series of processes.

[0040] Next, a specific case realized by the process of FIG. 4 will be described with reference to FIG. 6. In FIG. 6, a situation is assumed in which a medical institution to which a pediatric patient is admitted does not have a doctor who can diagnose the patient. The external telephone 70 is a telephone installed in the medical institution to which the pediatric patient is admitted. In T110, a doctor belonging to the medical institution in which the external telephone 70 is installed makes a call to the reception telephone 30.

[0041] In T112, the reception telephone 30 transmits call information indicating that a call has been made from the external telephone 70 and the telephone number of the external telephone 70 to the telephone exchange 100 via the communication I / F.

[0042] When the telephone exchange 100 receives the call information from the reception telephone 30 (YES in S10 of FIG. 4), in T114, it refers to the schedule table 118 and extracts medical institution A stored in association with May 17th (S12). That is, it extracts the doctor on duty for May 17th. Then, in T116, the telephone exchange 100 refers to the registration table 116 and extracts the telephone number "052-XXX-XXXX" and the email address "ABC@ZZZ" stored in association with medical institution A (S14). In T118, the telephone exchange 100 sends an email including a viewing URL to the extracted email address "ABC@ZZZ" as the destination (S16).

[0043] In T120, the telephone exchange 100 uses the telephone number of the external telephone 70 received in T112 and the telephone number of the registered telephone 40 extracted in T116 to connect the external telephone 70 and the registered telephone 40 to the conference circuit 20 (S18). This enables a call between the external telephone 70 and the registered telephone 40 via the conference circuit 20.

[0044] When a call is started between the external telephone 70 and the registered telephone 40, the telephone exchange 100 stores the voice data input to the voice input units of the external telephone 70 and the registered telephone 40 in the utterance content storage area 120 in T122 (S20).

[0045] Here, as described above, the patient brought into the medical institution where the external telephone 70 is installed is a pediatric patient, whereas the medical institution A, which is the doctor on duty, has a specialty classification of internal medicine or surgery, as shown in FIG. 2. For this reason, the medical institution A cannot diagnose the pediatric patient in detail. In such a case, the PC 80 accepts, in T123, an operation to select the URL for viewing included in the email received in T118 from the doctor (i.e., the doctor on duty) who responded to the call on the registered telephone 40. This allows the doctor to view the registered medical institution data screen 122 (see FIG. 5) displayed on the display unit 84, and understands that the medical institution B, which specializes in pediatrics, is present among the registered medical institutions. Then, in T124, the PC 80 accepts an operation input to select the connection button 124 corresponding to the medical institution B from the doctor on duty. Then, in T126, the PC 80 transmits connection request information including information indicating the medical institution B to the telephone exchange 100.

[0046] When the telephone exchange 100 receives the connection request information via the network I / F 104 in T126 (YES in S22), in T128, it refers to the registration table 116 and connects the registered telephone 50 installed in the medical institution B included in the connection request information to the conference circuit 20 (S24). This enables a three-way call between the external telephone 70, the registered telephone 40, and the registered telephone 50 via the conference circuit 20.

[0047] At T130, the telephone exchange 100 converts the voice data stored in the speech content storage area 120 into text data (S26). Then, at T132, the telephone exchange 100 refers to the registration table 116 and transmits the generated text data to the email address of the PC 90 installed in the medical institution B (S28).

[0048] In T133, the PC 90 displays the character string indicated by the text data received in T132 on the display unit 94. This allows the doctor belonging to medical institution B to understand the content of the telephone call between the doctor of the medical institution to which the pediatric patient was admitted and the doctor belonging to medical institution A before the doctor belonging to medical institution B joined the telephone conference.

[0049] Thereafter, when the three-way telephone conference ends, in T134, the external telephone 70 accepts input of a call-end operation. The call-end operation is, for example, pressing an end-call button provided on the external telephone 70. Note that the call-end operation input in T134 may be performed on the registered telephone 40 or the registered telephone 50. Then, in T136, the external telephone 70 transmits call-end information indicating that the call has ended to the telephone exchange 100.

[0050] When the telephone exchange 100 receives the call-end information at T136 (YES at S30), it disconnects all telephone sets connected to the conference circuit 20 from the conference circuit 20 at T138 (S32).

[0051] As described above, in the telephone conference system 10 of this embodiment, the user of the external telephone 70 simply makes a call to the reception telephone 30, and the external telephone 70 and the registered telephone 40 (i.e., the telephone installed at the medical institution A to which the on-duty doctor belongs) are connected to the conference circuit 20, and a call can be made between them. Also, the doctor who answers the call at the registered telephone 40 can select the medical institution B to which the pediatric specialist belongs, as necessary, and the telephone exchange 100 connects the registered telephone 50 to the conference circuit. In this way, in this telephone conference system 10, the caller can invite a third party (i.e., a specialist doctor belonging to the medical institution B to which the registered telephone 50 is installed) to participate in the telephone conference as necessary, which is highly convenient.

[0052] In addition, in the above-described system 10, the voice data input from the external telephone 70 and the registered telephone 40 is stored in the speech content storage area 120 of the telephone exchange 100, so that the voice data (speech content) can be used later. Also, the voice data is converted into text data and displayed as a character string on the display unit 84 of the PC 80 installed in the medical institution B, so that the specialist at the medical institution B can understand the content of the conversation between the external telephone 70 and the registered telephone 40 up until the specialist joined the telephone conference. Therefore, the specialist who joined the telephone conference later can quickly understand the content of the telephone conference.

[0053] Furthermore, in the above-described system 10, a telephone conference can be held without disclosing the telephone numbers and email addresses of each user (i.e., the users of the external telephone 70 and the registered telephones 40 to 60). This ensures confidentiality for each user of the system 10, which is also useful from the viewpoint of privacy protection.

[0054] (Correspondence) The registered telephones 40 and 50 are examples of a "first registered telephone" and a "second registered telephone", respectively. The PC 80 is an example of a "selection device". The speech content memory area 120 is an example of a "memory unit". The display unit 94 of the PC 90 is an example of a "display unit". Medical institutions A, B, and C are examples of a "first medical institution", a "second medical institution", and a "third medical institution", respectively.

[0055] Although specific examples of the technology disclosed in this specification have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and variations of the specific examples exemplified above. Modifications of the above-mentioned embodiments are listed below.

[0056] (Modification) In the above-mentioned embodiment, an example of using the system 10 in the medical field has been described. However, the application of the technology disclosed in this specification is not limited to the medical field. For example, the technology disclosed in this specification may be appropriately applied to other fields such as the legal field (lawyers, etc.) and the financial field (banks, etc.).

[0057] In the above-described embodiment, the registered telephone 40 and the PC 80 are installed in the medical institution A. However, the registered telephone 40 and the PC 80 may be integrated. That is, a single device having the functions of both the registered telephone 40 and the PC 80 may be installed in the medical institution A. For example, the registered telephone 40 may be equipped with a display unit, a wireless I / F connectable to the Internet 4, etc.

[0058] In the above embodiment, a three-party telephone conference has been described, but a four-party telephone conference is also possible. The system 10 may be configured to be able to simultaneously execute multiple telephone conferences. For example, two different medical institutions serving as contact points may be stored on the same day in the schedule table 118. In such a configuration, if a call is made to the reception telephone 30 from another external telephone while a certain telephone conference is in progress, the second medical institution will respond, allowing two telephone conferences to be executed simultaneously.

[0059] In addition, the external telephone 70 does not have to be installed in the medical institution. For example, it may be a mobile terminal owned by the family of the injured person or an ambulance staff member, and a telephone conference with the doctor on duty or a specialist may be held by calling the reception telephone 30 from the mobile terminal.

[0060] (Reference example) In the above-described embodiment, the doctor on duty conducts a three-way telephone conference by selecting the medical institutions that should participate in the telephone conference from the registered medical institution data screen 122. However, for example, a telephone number input field may be provided on the registered medical institution data screen 122. In this case, the doctor on duty may directly input a telephone number into the input field, and the telephone exchange 100 may connect the telephone line indicated by the telephone number to the conference circuit 20. This configuration is useful, for example, in a situation where the doctor on duty wants the patient's family or the like to participate in the telephone conference.

[0061] In addition, the technical elements described in this specification or drawings exert technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technologies exemplified in this specification or drawings achieve multiple objectives simultaneously, and achieving one of those objectives is itself technically useful.
