Description

  The present invention relates to a remote conference system, a remote conference method, a remote conference program, and a recording medium for performing a remote conference between a plurality of communication terminals connected to each other via a public communication network.

  In the teleconference system according to the first conventional technology, the connection source specifies the IP address or ISDN number of the connection destination, and if the connection destination can respond, communication between the connection source and the connection destination is performed. Once established, a remote conference such as a video conference is started. As long as the connected video conference system is powered on and connected to the network, the remote conference can always be started with the connection source.

  In the dial transmission / reception confirmation device according to the second prior art, the telephone number of the communication partner is stored in advance, and the telephone number of the other party is confirmed and confirmed when calling or receiving from the other party. The communication can be performed only when the phone number matches the phone number stored in advance (see Patent Document 1, for example).

  In the remote conference system according to the third conventional technology, the remote conference time zone, conference room name, conference room IP address, destination terminal IP address, etc. are reserved, and when the start time is reached, A remote conference can be started by selecting a desired conference room name from a connection destination list registered in advance.

  In the IP telephone system according to the fourth conventional technology, telephone conference registration management information including the start time of the telephone conference and the incoming number of the telephone terminal corresponding to the telephone conference participant name is generated, and the telephone conference registration management information is generated. On the basis of the above, at the conference call start time, a call can be made to the incoming number and the conference call can be automatically held (see, for example, Patent Document 2).

  In the reservation management method for a call system according to the fifth conventional technique, reservation information including a communication start time and a communication partner is registered, and when the communication start time is reached, communication with a communication terminal of a communication partner is performed according to the reservation information. Communication is started (see, for example, Patent Document 3).

  However, in the remote conference system according to the first prior art, an erroneous connection within the same segment at the connection destination or an erroneous connection to a similar ISDN number may occur. Due to this erroneous connection, there is a problem that a connection is made to the wrong destination that is not scheduled for a remote conference, or an additional connection is made during another conference.

  When the remote conference system is shared on the connection destination side, for example, by a plurality of companies having offices in the same building, there is a possibility of information leakage if the remote conference is started due to an erroneous connection. In addition, if the connection source is connected to the connection destination at a time different from the time of the remote conference scheduled by the connection source, there is a possibility of connection to another company that does not plan the remote conference.

  Since the dial transmission / reception confirmation device according to the second conventional technology can only transmit / receive to / from the other party of the telephone number stored in advance, the error in the remote conference system according to the first conventional technology described above. Unable to solve the connection problem. Moreover, in the dial transmission / reception confirmation device, it is difficult to manage the parties to be transmitted and received for each time.

  In the remote conference system according to the third conventional technique, the conference room name and the IP address assigned to the conference room are preset as the connection destination list, but the connection destination is erroneously set in the conference room name and the IP address. Judgment may result in incorrect connection to unreserved conference rooms. In the remote conference system according to the third prior art, there is a risk that the remote conference may be started by an operation by a person other than the remote conference participant, and there is a risk of information leakage due to impersonation.

  In the IP telephone system according to the fourth conventional technology, even when the other party's conference call participant is absent, the conference call is automatically generated at the conference call start time. There is a risk that information will be leaked when a conference call is started with a person.

  In the reservation management system for a call system according to the fifth conventional technology, since communication is started with the communication terminal of the other party when the communication start time comes, the identity of the operator of the communication terminal of the other party is confirmed. There is a risk that information cannot be leaked due to a call with a person other than the person who made the reservation.

  FIG. 6 is a flowchart showing processing when a conference room is reserved in the remote conference system 1. When the reservation person operates the connection destination terminal 3b to make a reservation for the remote conference, the process proceeds to step A0 and the process is started.

  In step A1, after the communication between the connection destination terminal 3b and the conference reservation device 4 is established, the reservation date, the conference start time, the conference end time, the name of the reservation person, the remote conference are set as the reservation request information. The room name, IP address or ISDN number, destination contact person name, destination IP address or destination ISDN number are input to the connection destination terminal 3b. The inputted reservation request information is transmitted from the connection destination terminal 3b to the conference reservation device 4.

  In step A2, the reservation control unit 51 of the conference reservation device 4 determines whether or not there is any overlap between the remote conference room name and reservation date / time in the received reservation request information and the remote conference room name and reservation date / time in the reservation information. Determine. The reservation date and time are a reservation date, a conference start time, and a conference end time. Thereby, the reservation control unit 51 can prevent the same remote conference room from being reserved twice in the same time zone of the same date in the reservation information. If the reservation control unit 51 determines that there is no overlap between the remote conference room name and the reservation date and time, the process proceeds to step A3, and if it is determined that there is an overlap between the remote conference room name and the reservation date and time, the process proceeds to step A1.

  In step A3, the reservation control unit 51 generates a reservation number for the reserved remote conference. Further, the reservation control unit 51 associates the generated reservation number with the reservation request information, and stores it in the reservation storage unit 52 as reservation information.

  In step A4, the reservation control unit 51 notifies the reservation person of the generated reservation number. Specifically, the reservation control unit 51 outputs reservation number information indicating the generated reservation number. The reservation number information is transmitted to the connection destination terminal 3b by the reservation communication unit 53.

Specifically, the reservation number information is transmitted from the connection destination terminal 3b to the connection source terminal 3a and stored in the storage unit of the connection source terminal 3a. Further, the reservation person may notify the reservation person in charge of the reservation number by e-mail, facsimile, telephone or the like without using the remote conference system 1.

  FIG. 7 is a diagram illustrating a processing procedure for starting a remote conference between the connection source terminal 3a and the connection destination terminal 3b. When the start of the remote conference reserved from the connection source terminal 3a to the connection destination terminal 3b is requested, the process proceeds to step B1 and the process is started.

  In step B1, the connection source terminal 3a receives, as a start request, the IP address or ISDN number that is identification information of the connection source terminal 3a, and the IP address or ISDN number that is identification information of the connection destination terminal 3b input by the operation. Is transmitted to the connection destination terminal 3b.

  In step B2, the connection destination terminal 3b requests the conference reservation device 4 to check the conference reservation. Specifically, the connection destination terminal 3b transmits the identification information of the connection destination terminal 3b and the connection source terminal 3a received from the connection source terminal 3a to the conference reservation device 4 as reservation specifying information. When the conference reservation device 4 receives the identification information of the connection destination terminal 3b and the connection source terminal 3a from the connection destination terminal 3b, the conference reservation device 4 stores the reservation information based on the identification information and the request date information of the connection destination terminal 3b and the connection source terminal 3a. The reservation status of the remote conference reserved between the connection destination terminal 3b and the connection source terminal 3a is extracted from the reservation information stored in the unit 52.

  The reservation status is information relating to whether or not a remote conference is reserved, and is information representing, for example, an extraction number or an NG number. The NG number is a number generated by the reservation conference device when the remote conference reserved between the connection destination terminal 3b and the connection source terminal 3a is not in the reservation information.

  In step B3, the conference reservation device 4 transmits the result of the conference reservation check to the connection destination terminal 3b. As a result of the check, the conference reservation device 4 transmits the remote conference reservation status of the connection source terminal 3a at the current time of the conference room of the connection destination terminal 3b to the connection destination terminal 3b. In step B4, the connection destination terminal 3b transmits the received reservation status to the connection source terminal 3a, and confirms whether or not to establish a communication connection between the connection source terminal 3a and the connection destination terminal 3b.

  In step B5, the terminal control unit 21 of the connection source terminal 3a, which is a determination unit, compares the reservation number stored in the terminal storage unit 22 with the extracted number received as the reservation status. The extraction number received as the reservation status and the NG number described later are extraction identification information. The terminal control unit 21 of the connection source terminal 3a uses the extraction number indicated by the extraction number information output by the reservation control unit 51 and the reservation number information output by the reservation control unit 51 when the remote conference is reserved. The numbers are compared to determine whether they match. If the terminal control unit 21 of the connection source terminal 3a determines that the reservation number and the extraction number match, the terminal control unit 21 retransmits the start request to the connection destination terminal 3b.

  In step B6, the terminal control unit 21 of the connection destination terminal 3b that is the remote conference control unit transmits start request information when the terminal control unit 21 of the connection source terminal 3a determines that the extraction number and the reservation number match. The remote request between the connection source terminal 3a and the connection destination terminal 3b that received the start request information is allowed to start, and when it is determined that the extraction number and the reservation number do not match, the start request information is transmitted. The remote conference is prevented from starting between the connection source terminal 3a and the connection destination terminal 3b that has received the start request information. In response to the start request from the connection source terminal 3a, the connection destination terminal 3b completes the communication connection between the connection source terminal 3a and the connection destination terminal 3b, and the remote conference is started.

If the reservation control unit 31 determines that there is a start request, the process proceeds to step J2, and if it is determined that there is no start request, the process in step J1 is performed again.

  In step J2, the reservation control unit 31 receives the unique ID and the terminal identification information of the connection source terminal 103a from the connection source terminal 103a. In Step J3, the reservation control unit 31 searches for reservation information of the reservation person, that is, the operator of the connection source terminal 103a, using the received unique ID. The reservation control unit 31 searches for reservation information including the unique ID of the reservation user from one or a plurality of reservation information 116 stored in the reservation storage unit 52 using the unique ID of the reservation user as a search item. Steps J3 to J11 are search and extraction processes.

  In Step J4, the reservation control unit 31 determines whether or not the corresponding reservation information, that is, the reservation information including the unique ID of the reservation person is in the reservation storage unit 52. If the reservation control unit 31 determines that there is corresponding reservation information, the process proceeds to step J6. If it is determined that there is no corresponding reservation information, the process proceeds to step J5.

  In Step J5, the reservation control unit 31 transmits “99999999” as the NG number to the connection source terminal 103a, and proceeds to Step J14. In Step J6, the reservation control unit 31 converts the corresponding reservation information, that is, reservation information including each item associated with the unique ID of the reservation person, into one or more reservation information stored in the reservation storage unit 52. It is extracted from the inside and stored in the reservation storage unit 52.

  In step J7, the reservation control unit 51 acquires the current date and time from the date and time acquisition unit 54. The information indicating the acquired date is request date information. In Step J8, the reservation control unit 51 uses the request date information as a search item from the reservation information stored in Step J6, and the reservation includes the date and time indicated by the request date information in the date and time range indicated by the reservation time zone information. Search for information.

  In step J11, the reservation control unit 51 searches the reservation information stored in step J10 for reservation information including the identification information of the connection source terminal 103a using the identification information of the connection source terminal 103a as a search item.

  In step J12, the reservation control unit 51 determines whether there is reservation information corresponding to the search item in step J11. If the reservation control unit 51 determines that there is corresponding reservation information, the process proceeds to step J13. If it is determined that there is no corresponding reservation information, the process proceeds to step J5.

  In step J13, the reservation control unit 51 extracts the terminal identification information of the partner as extraction information from the reservation information corresponding to the search item in step J12. The reservation control unit 51 transmits the extracted terminal identification information of the other party, for example, the terminal identification information of the connection destination terminal 103b to the connection source terminal 103a.

  In step J14, the reservation control unit 51 determines whether or not information indicating disconnection of communication has been received from the connection source terminal 103a. If the reservation control unit 51 determines that the information indicating that the communication is to be disconnected has been received, the process proceeds to step J15. If it is determined that the information indicating that the communication is to be disconnected has not been received, the step J14 is performed again. The process in is performed. In step J15, the reservation control unit 51 disconnects communication with the connection source terminal 103a, proceeds to step J16, and ends the process.

  In the present embodiment, the reservation information 67 stored in the reservation storage unit 52 includes reservation specifying information and extracted reservation information, and the reservation specifying information includes a unique ID. The information may include a unique ID. In this case, as a remote conference start request, the terminal identification information of the connection destination terminal 103b is input to the connection source terminal 103a, and the conference reservation device 104 uses the terminal identification information of the connection destination terminal 103b as a search item to input the corresponding reservation information.

As a result, the connection source terminal 103a can start the remote conference after confirming that the unique ID transmitted from the conference reservation device 104 is the correct unique ID. Therefore, the connection source terminal 103a can confirm that the connection destination terminal 103b that performs communication for the remote conference is the reserved connection destination terminal 103b, and thus prevents erroneous connection between the communication terminals 103. be able to.

  In the embodiment described above, the terminal control unit 21 executes the program stored in the terminal storage unit 22, and the reservation control unit 51 executes the program stored in the reservation storage unit 52, thereby realizing the above-described function. However, the program for realizing the above-described functions is not limited to being stored in the terminal storage unit 22 and the reservation storage unit 52, and may be recorded on a computer-readable recording medium. . The recording medium may be, for example, a recording medium that can be read by providing a program reading device as an external storage device (not shown) in the remote conference systems 1 and 101 and inserting the recording medium therein. It may be a storage device.

  Any recording medium may be used as long as the stored program is accessed from a computer and executed. Alternatively, any recording medium may be configured such that the program is read, the read program is stored in the program storage area of the storage device, and the program is executed.

The recording medium configured to be separable from the remote conference systems 1 and 101 is, for example, a tape recording medium such as a magnetic tape / cassette tape, a magnetic disk such as a flexible disk / hard disk, or a CD-ROM (Compact Disk Read Only Memory). / MO (
Magnet-type optical disks (MDs) / MDs (Mini Discs) / DVDs (Digital Versatile Disks) / CD-Rs (Compact Disk Recordables) / Blu-ray discs and other optical discs, IC (Integrated Circuit) cards (including memory cards) ) / Card-type recording media such as optical cards, or mask ROM / EPROM (Erasable Programmable)
Read Only Memory) / EEPROM (Electrically Erasable Programmable Read Only
Memory) / a recording medium that carries a fixed program including a semiconductor memory such as a flash ROM.

Further, the remote conference systems 1 and 101 may be configured to be connectable to a communication network, and the program may be supplied via the communication network. The communication network is not particularly limited. For example, the Internet, intranet, extranet, LAN (Local Area Network), ISDN (Integrated Services Digital Network), VAN (Value Added Network), CATV (Community Antenna Television) communication network. A communication network such as a virtual private network, a telephone line network, a mobile communication network, or a satellite communication network can be used. Also, the transmission medium constituting the communication network is not particularly limited. For example, IEEE1394, USB (Universal Serial Bus), power line carrier, cable TV line, telephone line, ADSL (Asymmetric Digital Subscriber)
Line (wire) lines, etc., IrDA (Infrared Data Association) or infrared light used for remote control, Bluetooth (registered trademark), 802.11 wireless, HDR (High Data Rate), mobile phone network, satellite line, terrestrial digital It can also be used wirelessly such as on the network. The present invention can also be realized in the form of a computer data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

  As described above, the remote conference systems 1 and 101 include the reservation storage unit 52 that is a reservation information storage unit and the reservation control unit 51 that is a search extraction unit. The reservation storage unit 52 stores reservation information 67 and 116 related to a reserved remote conference when information indicating that one or more remote conferences between the plurality of communication terminals 3 and 103 are reserved is input. . The plurality of communication terminals 3 and 103 are connected to be communicable with each other. The reservation information 67 and 116 includes a plurality of types of items, and is stored in association with each remote conference. When the information indicating that the reservation specifying information has been transmitted is input, the reservation control unit 51 specifies the remote conference reservation information 67 and 116 reserved for one communication terminal 3, 103 based on the reservation specifying information. To do. The reservation specifying information is transmitted from one communication terminal 3,103 among the plurality of communication terminals 3,103. The reservation specifying information is included in the remote conference reservation information 67 and 116 reserved for one communication terminal 3 and 103. The reservation specifying information is for specifying the reserved remote conference reservation information 67 and 116 from one or a plurality of remote conference reservation information 67 and 116. The reservation control unit 51 extracts items different from the reservation specifying information from the specified remote conference reservation information 67 and 116, and outputs the extracted identification information.

  As a result, the extracted identification information includes items different from the reservation specifying information, and therefore, the relevance between the extracted identification information and the reservation specifying information associated in the remote conference systems 1, 101 is indicated by the communication terminals 3, 103 or this. It can be confirmed by an operator who operates the. Therefore, the remote conference systems 1 and 101 can prevent erroneous connection between the communication terminals 3 and 103.

  Furthermore, the remote conference system 1 further includes a reservation control unit 51 which is a reservation identification information generation unit. The reservation control unit 51 generates reservation identification information that is unique identification information associated with each reserved remote conference, and outputs the generated reservation identification information. At least one of the reservation specifying information and the extracted identification information includes reservation identification information of a reserved remote conference for one communication terminal.

  Thus, the reserved remote conference for one communication terminal 3 can be confirmed using the reservation identification information. Therefore, the remote conference system 1 can reliably prevent erroneous connection between the communication terminals 3.

  Further, in the remote conference system 1, the reservation information 67 includes reservation identification information. The reservation control unit 51 requests the start of a remote conference to at least one communication terminal 3 among the remaining communication terminals 3 excluding one communication terminal 3 from one communication terminal 3 among the plurality of communication terminals 3. When the information indicating that the start request information to be transmitted is input, the reservation specifying information is transmitted, and the communication terminal 3 that has transmitted the start request information from one or a plurality of reservation information stored in the reservation storage unit 52 And reservation information related to the remote conference between the communication terminal 3 that has received the start request information is searched based on reservation specifying information representing a predetermined search item different from the reservation identification information in the reservation information. Reservation identification information is extracted from the reserved information and output as extracted identification information.

  As a result, the reservation control unit 51 searches for reservation information based on a predetermined search item different from the reservation identification information, for example, identification information of the communication terminal 3. The remote conference reservation identification information can be estimated and output as extracted identification information. Therefore, for example, the operator or the computer of the remote conference system 1 compares the reservation identification information with the extracted identification information, and if the reservation identification information does not match the extracted identification information, a remote conference start request is made. It can be determined that at least one of the communication terminals 3 is not the reserved communication terminal 3 of the remote conference. Thereby, in the remote conference system 1, it is possible to prevent erroneous connection by the communication terminal 3 different from each communication terminal 3 of the reserved remote conference. Accordingly, the remote conference system 1 prevents the remote conference from being started with the communication terminal 3 different from the reserved remote conference communication terminal 3 and prevents information leakage to the different communication terminal 3. Can do.

  Furthermore, the remote conference system 1 further includes a terminal control unit 21 of the connection source terminal 3a that is a determination unit and a terminal control unit 21 of the connection destination terminal 3b that is a remote conference control unit. The terminal control unit 21 of the connection source terminal 3a compares the extracted identification information output by the reservation control unit 51 with the reservation identification information output by the reservation control unit 51 when the remote conference is reserved. It is determined whether or not to do. When the terminal control unit 21 of the connection source terminal 3a determines that the extracted identification information and the reservation identification information match, the terminal control unit 21 of the connection destination terminal 3b and the communication terminal 3 that transmitted the start request information and the start request information Is permitted to start a remote conference with the communication terminal 3 that has received the request, and when it is determined that the extracted identification information and the reservation identification information do not match, the communication terminal 3 that has transmitted the start request information and the start request information are The start of the remote conference with the received communication terminal 3 is blocked.

  As a result, the remote conference system 1 compares the reservation identification information with the extracted identification information, and if the reservation identification information does not match the extracted identification information, each communication terminal 3 for which a remote conference start request has been made. It can be determined that at least one of the communication terminals 3 of the reserved remote conference is not. Therefore, in the remote conference system 1, erroneous connection by the communication terminal 3 different from each communication terminal 3 of the reserved remote conference can be automatically prevented by a series of processes. Thus, the remote conference system 1 prevents the remote conference from being started with the communication terminal 3 different from the reserved remote conference communication terminal 3, and prevents information leakage to the different communication terminals 3. be able to.

  Furthermore, the reservation information stored in the reservation storage unit 52 includes reservation terminal information related to at least one communication terminal 3 among the communication terminals 3 of the reserved remote conference. As the predetermined search item, request terminal information related to at least one communication terminal 3 among the communication terminal 3 that has transmitted the start request information and the communication terminal 3 that has received the start request information is used. The reservation control unit 51 searches for reservation information in which at least a part of the reservation terminal information matches at least a part of the requested terminal information from one or a plurality of reservation information, and extracts reservation identification information from the searched reservation information And output as extraction identification information.

  As a result, the reservation control unit 51 extracts the extracted identification information using the requested terminal information as a search item different from the reservation identification information. Therefore, if the extracted identification information and the reservation identification information do not match, It can be determined that at least one of the communication terminals 3 for which the start request has been made is not the reserved communication terminal 3 of the remote conference. Therefore, the remote conference system 1 accurately determines whether or not each communication terminal 3 for which a remote conference start request is made is each reserved remote conference communication terminal 3 using the requested terminal information. can do.

  Furthermore, the remote conference system 1 further includes a date and time acquisition unit 54 that acquires the date and time when the start request is made and outputs request date information representing the acquired date and time. The reservation information stored in the reservation storage unit 52 includes reservation time zone information related to the date and time range of the reserved remote conference. As the predetermined search item, the date and time indicated by the request date information output by the date and time acquisition unit 54 is used. The reservation control unit 51 searches for reservation information that includes the date and time indicated by the request date information within the date and time range indicated by the reservation time zone information from one or a plurality of reservation information, and sets reservation identification information from the searched reservation information. Extract and output as extraction identification information.

  As a result, the reservation control unit 51 extracts the extracted identification information using the request date information as a search item different from the reservation identification information. Therefore, if the extracted identification information and the reservation identification information do not match, It can be determined that the date when the start request is made is not within the date range of the reserved remote conference. Therefore, the remote conference system 1 can detect an error in the date and time of the remote conference when the communication terminal 3 makes a remote conference start request. In addition, the remote conference system 1 can prevent an erroneous connection due to an error in the date and time when the start request is made even when each communication terminal 3 is shared by a plurality of operators. Therefore, the remote conference system 1 can prevent a person other than the reserved remote conference participant from holding the remote conference by mistake.

  Furthermore, the remote conference system 1 further includes a conference reservation device connected to at least one communication terminal 3 among the plurality of communication terminals 3. The conference reservation apparatus includes a reservation control unit 51, a reservation storage unit 52, and a reservation control unit 51.

  Thereby, in the remote conference system 1, the remote conference reservation device 4 different from the communication terminal 3 is separately provided, thereby reducing the processing load on each communication terminal 3 and smoothing the remote conference between the communication terminals 3. Can be done. In the remote conference system 1, the remote conference reservation device 4 can be shared by a plurality of communication terminals 3. Therefore, in the remote conference system 1, all remote conferences between the communication terminals 3 can be centrally managed by the remote conference reservation device 4.

  Furthermore, the communication terminal 3 that transmitted the start request information is configured to include the terminal control unit 21 of the connection source terminal 3a. The communication terminal 3 that has received the start request information includes the terminal control unit 21 of the connection destination terminal 3b. The reservation identification information compared by the terminal control unit 21 of the connection source terminal 3a is the communication terminal 3 that has received the start request information from the reservation control unit 51 when a remote conference is reserved by the communication terminal 3 that has received the start request information. Is sent to the communication terminal 3 that transmitted the start request information. The extracted identification information compared by the terminal control unit 21 of the connection source terminal 3a transmits the start request information via the communication terminal 3 that has received the start request information from the reservation control unit 51 when the start request information is transmitted. It is sent to the communication terminal 3.

  Thereby, in the remote conference system 1, after one communication terminal 3 makes a start request, the reservation identification information and the extracted identification information can be compared in one communication terminal 3. Therefore, the remote conference system 1 can prevent one communication terminal 3 that is a connection source from being erroneously connected to the other communication terminal 3 that is a connection destination. In addition, when one communication terminal 3 that is a connection source starts a remote conference with the other communication terminal 3 that is a connection destination, it can confirm that the connection destination is not impersonating. Therefore, the remote conference system 1 can prevent impersonation in the remote conference and prevent information leakage.

  Furthermore, at least one of the reservation specifying information and the extracted identification information is authentication data for personally authenticating a reservation person who has reserved a remote conference for one communication terminal 103, or a reservation person corresponding to authentication data individually. A unique ID that is identification information is included.

  This makes it possible to determine whether or not the operator who transmitted the reservation specifying information matches the reservation person who reserved the remote conference. Therefore, erroneous connection can be prevented, and further, the start of the remote conference by a person different from the reservation person who reserved the remote conference can be prevented.

  Furthermore, the remote conference system 101 further includes a terminal control unit 21 of the connection source terminal 103a which is a determination unit. The reservation information 116 includes a unique ID which is reservation person identification information. The terminal control unit 21 of the connection source terminal 103a determines whether or not the authentication data input by the operator of the communication terminal 103 that transmitted the reservation specifying information corresponds to the unique ID.

  As a result, the reservation information 116 does not include authentication data that tends to have a large amount of information, and data corresponding to the authentication data can be stored as a unique ID having a smaller information amount than the authentication data. In addition, since the determination unit is included, erroneous connection can be prevented, and further, the start of the remote conference by a person different from the reservation person who reserved the remote conference can be prevented.

  Furthermore, a reservation person identification information generating unit that generates different unique IDs corresponding to a plurality of authentication data based on authentication data input by the reservation person and the operator is further included.

  As a result, it is possible to provide a common reservation person identification information generation unit that individually generates a unique ID from input authentication data for both the reservation person and the operator. Therefore, there is no need to transmit authentication data that tends to have a large amount of information between the reservation person identification information generation unit and other parts other than this. Therefore, it is possible to speed up the processing compared to the case where authentication data needs to be transmitted.

  Furthermore, the reservation specifying information includes a unique ID generated based on the operator authentication data by the reservation person identification information generation unit.

  As a result, the operator can transmit the reservation specifying information for the reserved remote conference as the start request only by inputting the authentication data. If the operator does not match the reservation person, a unique ID that matches the unique ID included in the reservation information 116 cannot be included in the reservation specifying information. Therefore, only when the operator matches the reservation person, A start request can be made for a reserved remote conference. Therefore, it is possible to determine whether or not the requested remote conference is a reserved remote conference and to start the reserved remote conference only by inputting authentication data. As a result, the procedure necessary for starting the reserved remote conference can be simplified as much as possible, and the convenience can be enhanced.

  Furthermore, the remote conference system 101 further includes a remote conference control unit. The reservation information 116 includes terminal identification information of another communication terminal 103b for which a remote conference is reserved with one communication terminal 103a. When the reservation control unit 51 outputs the terminal identification information of the other communication terminal 103b as the extracted identification information, the remote conference control unit starts a remote conference between the one communication terminal 103a and the other communication terminal 103b. Is acceptable.

  Thereby, the participant of the remote conference can start a remote conference with another reserved communication terminal only by inputting authentication data into one communication terminal. Therefore, the remote conference system 101 can prevent a third party who has not reserved the remote conference from starting the remote conference, and can simplify the start operation of the remote conference as much as possible to improve convenience. it can.

  Further, the remote conference method includes steps A3 and F3 which are reservation information storing steps, and steps E3 to E11 and J3 to J11 which are search extracting steps. In the reservation information storage step, when information indicating that one or more remote conferences between the plurality of communication terminals 3 and 103 are reserved, reservation information 67 and 116 relating to the reserved remote conference is stored. . The plurality of communication terminals 3 and 103 are connected to be communicable with each other. The reservation information 67 and 116 includes a plurality of types of items, and is stored in association with each remote conference. In the search and extraction process, when information indicating that the reservation specifying information has been transmitted is input, the remote conference reservation information 67 and 116 reserved for one communication terminal 3, 103 is specified based on the reservation specifying information. . The reservation specifying information is transmitted from one communication terminal 3,103 among the plurality of communication terminals 3,103. The reservation specifying information is included in the remote conference reservation information 67 and 116 reserved for one communication terminal 3 and 103. The reservation specifying information is for specifying the reserved remote conference reservation information 67 and 116 from one or a plurality of remote conference reservation information 67 and 116. In the search and extraction step, an item different from the reservation specifying information is extracted from the specified remote conference reservation information 67 and 116 and output as extracted identification information.

  As a result, the extracted identification information includes items different from the reservation specifying information, so that the relevance between the extracted identification information associated with the reservation information storing step and the reservation specifying information can be determined by operating the communication terminals 3, 103 or this. It can be confirmed by the operator who performs the operation. Therefore, in the remote conference method, an erroneous connection between the communication terminals 3 and 103 can be prevented.

  Further, the remote conference program causes the computer to function as the remote conference system 1,101.
