Description

  The present invention relates to a usage status management apparatus, usage status management system, usage status management method, and usage status management program for managing usage status.

  In recent years, reservation management systems for managing rental information in predetermined places such as conference rooms and reception rooms have been widely used. In this reservation management system, information related to rental of conference rooms and reception rooms is collectively managed on the system. The user can confirm the reservation status from the reservation table generated by the system. The user can secure a reservation or cancel a reservation based on the reservation table.

  However, a general reservation management system only manages the reservation status made based on the user's operation, and manages whether conference rooms and reception rooms are actually used as reserved. I did not.

  Therefore, even if there is a conference room that has been reserved but not actually used, users other than the reservation person who wants to use this conference room can easily determine the occupancy status of the conference room. There wasn't.

  As a result, even though the conference room can be used, a user who wants to use the conference room cannot use the conference room and cannot efficiently use the conference room.

  In consideration of such a situation, Patent Literature 1 and Patent Literature 2 describe an example of a technique for promoting efficient use of a conference room.

  Patent Document 1 discloses a conference room reservation device that reflects a user's occupancy status based on a telephone response.

  When the conference room reservation device described in Patent Document 1 calls the conference room telephone when the conference room reservation start date and time is reached, and receives an input for confirming the use of the conference room from the telephone Confirm the use of the conference room. On the other hand, when an input for confirming use of the conference room is not accepted from the conference room telephone, a call is made to the reservation person's telephone or the conference room telephone, and the input relating to the reservation information is accepted from the telephone that has made the call.

  As described above, the conference room reservation apparatus described in Patent Document 1 manages the actual occupancy status of the conference room by checking the presence or absence of a response by the reservation person using a telephone.

  Patent Document 2 describes that terminal location information is acquired from a terminal carried by the user, and whether or not the user is in a conference room is determined based on the acquired location information. Yes. However, in this method, when the user forgets to place the terminal at his / her seat or the like, it cannot be accurately determined whether or not the user is in the conference room. Therefore, in Patent Document 2, a conference room terminal in which a sensor is mounted is further installed in the conference room, and by using this conference room terminal, a user's room such as whether the user is in the conference room or not is used. A conference room reservation device for managing the situation is disclosed. Here, in the conference room terminal described in Patent Document 2, a brightness sensor and a sound sensor for detecting an environmental change in the conference room are mounted. And based on the content of the environmental change of the meeting room which this sensor detected, each meeting room terminal is determining whether the user is in the meeting room.

  The above is the outline of this embodiment.

  Next, this embodiment will be described in detail with reference to the drawings.

  First, FIG. 1 is a block diagram showing the overall configuration of an occupancy status management system 1 according to an embodiment of the present invention.

  Referring to FIG. 1, the occupancy status management system 1 includes a private branch exchange 10, a reservation management server device 20, a plurality of telephones 30 (a first telephone 30-1, a second telephone 30-2, and an nth telephone 30. -N), including the user terminal 50 and the LAN 60. Further, the present room status management system 1 is installed in a building in which a plurality of conference rooms (first conference room 40-1, second conference room 40-2, and nth conference room 40-n) exist. The

  In the following description, when the first telephone 30-1, the second telephone 30-2, and the nth telephone 30-n are referred to collectively or without specifying any one, the “telephone 30” is appropriately used. Call it. Similarly, when the first conference room 40-1, the second conference room 40-2, and the nth conference room 40-n are referred to collectively or without specifying any one, the “conference room” is appropriately used. 40 ".

  The first telephone 30-1, the second telephone 30-2, and the n-th telephone 30-n, which are a plurality of telephones 30, are each a first conference room 40-1 that is a separate conference room. These are multifunctional telephones installed in the second conference room 40-2 and the n-th conference room 40-n. Here, in the present embodiment, it is assumed that the telephones 30 are installed in the same room with the numbers at the end of the symbols.

  Furthermore, it is assumed that each telephone 30 is assigned a unique extension or outside telephone number. Specifically, it is assumed that the telephone number “XX1” is assigned to the first telephone 30-1. Further, it is assumed that the telephone number “XX2” is assigned to the second telephone 30-2. Furthermore, it is assumed that the telephone number “XXn” is assigned to the n-th telephone 30-n.

  The private branch exchange 10 and the reservation management server device 20 are connected so as to communicate with each other. Further, the private branch exchange 10 is connected to each telephone 30 installed in each conference room 40. Further, the private branch exchange 10 and the reservation management server device 20 are connected to the user terminal 50 via a LAN (Local Area Network).

  Next, functional blocks included in each of these devices will be described in detail with reference to the drawings.

  First, referring to FIG. 2, the private branch exchange 10 includes a call control unit 11, a switch side control unit 12, a storage unit 13, a sound detection unit 14, and a voice analysis unit 15.

  The call control unit 11 is a part for realizing a function as a general private branch exchange. The call control unit 11 accommodates each telephone 30 and implements an extension call between the telephones 30 by performing call control. The call control unit 11 may be connected to an external line (not shown), and the call control unit 11 may realize a call between each telephone 30 and a telephone connected to the external line.

  The exchange-side control unit 12 is an arithmetic processing unit for controlling the private branch exchange 10 as a whole. The exchange-side controller 12 can be realized by an arithmetic processing device such as a CPU (Central Processing Unit) and a storage device, for example. Then, the exchange-side control unit 12 reads software stored in a storage unit 13 to be described later, and performs arithmetic processing based on this software. Then, the exchange side control unit 12 controls the hardware included in the private branch exchange 10 based on the result of the arithmetic processing. That is, 10 can be realized by cooperation of hardware and software.

  The storage unit 13 is a storage unit for storing various types of information. For example, software for controlling the private branch exchange 10 described above is stored in the storage unit 13.

  The sound detection unit 14 and the voice analysis unit 15 are parts for determining the usage status of the conference room 40. The sound detection unit 14 and the voice analysis unit 15 analyze the sound in the conference room heard from the microphone of the telephone 30 managed by the private branch exchange 10 and determine the usage status of the conference room 40 based on the analysis result.

  Specifically, the call control unit 11 refers to information (details will be described later) indicating the reservation status of each conference room 40 managed by the private branch exchange 10 and is provided in each conference room 40 that has been reserved. The telephone number of each telephone 30 is obtained. Then, the exchange-side control unit 12 calls each telephone 30 via the call control unit 11 based on the acquired telephone number. In response to this, each telephone 30 to which such a call arrives automatically answers. The sound heard from the microphone of the telephone 30 by the automatic response of each telephone 30 is output to the sound detector 14 via the call controller 11. Then, the sound heard from the microphone of the telephone 30 is detected by the sound detection unit 14. The detected sound is output to the voice analysis unit 15. The voice analysis unit 15 analyzes the sound input from the sound detection unit 14 and determines whether a person is present in the conference room 40 based on the analysis result. For example, when the sound input from the sound detection unit 14 is analyzed and a sound that is considered to be a human voice is included, it is determined that a person is present in the conference room 40. Further, for example, when a sound of a certain level is included, it is considered that this is a sound generated by the movement of a person who is in the room, so that a person is present in the conference room 40. It is determined that When it is determined that a person is present in the conference room 40, the conference room 40 is determined to be “in use”. On the other hand, if it is determined that no person is present in the conference room 40 for reasons such as the absence of sounds that are considered to be generated due to human voice or human movement, It is determined that 40 is “unused”.

  It should be noted that a user who is present in the conference room 40 is not aware of the voice being collected by the telephone 30 for the purpose of determining the usage status of the conference room 40, and other users in the conference room 40. We are having a regular meeting with For this reason, the content of the conversation may include information that should be kept secret outside the conference. Therefore, based on the viewpoint of enhancing the confidentiality of the conference content, the audio of the conference room is not recorded or left in the text data etc. by voice recognition etc., only whether there are people in the conference room It is good to judge. The determination result is output to the exchange-side controller 12.

  Next, referring to FIG. 3, the reservation management server device 20 includes a database 21, a reservation management server device side control unit 22, and a Web site generation unit 23.

  The database 21 is a storage device that stores various types of information as, for example, a table. The database 21 stores, for example, “conference reservation information 21-a”, which is information related to conference room reservation, and “timer information 21-b”, which is information related to a timer used when monitoring the conference room. The Details of these pieces of information will be described later with reference to FIGS. Also, these pieces of information are updated to the latest contents by the reservation management server device side control unit 22.

  The reservation management server device side control unit 22 is an arithmetic processing unit for controlling the private branch exchange 10 as a whole. The reservation management server device side control unit 22 can be realized by, for example, an arithmetic processing device such as a CPU (Central Processing Unit) and a storage device, like the exchange side control unit 12. Then, the reservation management server apparatus side control unit 22 reads the software stored in the database 21 or a storage unit (not shown) and performs arithmetic processing based on the software. And the reservation management server apparatus side control part 22 controls the hardware contained in the reservation management server apparatus 20 based on the result of this arithmetic processing. That is, the reservation management server device 20 can be realized by cooperation of hardware and software.

  The website creation unit 23 is a part that creates a website for the user to browse the usage status of the conference room. The website generation unit 23 generates a website based on each information stored in the database 21. The Web site is a site for displaying a reservation table representing each piece of information stored in the database 21, for example. This Web site also provides a user interface for the user to make a reservation, for the user to change the reservation, and for the user to cancel the reservation.

  Next, referring to FIG. 3, the telephone 30 includes a display unit 31, a telephone function unit 32, a microphone 33, an operation reception unit 34, and a speaker 35.

  The display unit 31 is a display device for displaying information transmitted from the private branch exchange 10, the current time, the dial number being input, and the like. The display unit 31 is realized by, for example, a liquid crystal display (LCD).

  The telephone function unit 32 is a part for realizing a telephone function on the telephone 30. The telephone function unit 32 performs general voice call processing and the like. The telephone function unit 32 cooperates with hardware included in the telephone 30, so that the telephone 30 functions as a telephone. The telephone function unit 32 may be realized by hardware, but may be realized by a combination of hardware and software.

  The microphone 33 is a microphone for collecting sounds around the telephone 30. The microphone 33 may be unique to the present embodiment, but may be a microphone provided in a normal telephone for making a so-called hands-free call.

  The operation reception unit 34 is a part that receives a user operation. The user's operation is, for example, dial input of a destination telephone number or switching of display information. The operation reception unit 34 can be realized by a button such as a numeric keypad. A predetermined function may be associated with a predetermined button. Note that the display unit 31 and the operation receiving unit 34 may be integrated and realized by a touch panel.

  The speaker 35 is a speaker for outputting sounds around the telephone 30. The operation reception unit 34 may be unique to the present embodiment, but may be a speaker provided in a normal telephone for performing a so-called hands-free call.

  In general, a telephone receiver is connected to the telephone 30, but it is considered that the telephone receiver is not directly related to the gist of the present invention.

  The user terminal 50 is a terminal used by the user, and can be realized by, for example, a PC (Personal Computer) or a smartphone. As described above, the user terminal 50 can communicate with the private branch exchange 10 and the reservation management server device 20 via the LAN 60.

  A user who wants to use the conference room can check the usage status by connecting to the website created by the website creation unit 23 using a browser incorporated in the user terminal 50 or the like.

  In addition, a user connected to the website by the user terminal 50 makes a reservation, changes the reservation, or cancels the reservation by an operation using a user interface provided on the website. The content of the operation is transmitted to the reservation management server device 20. The reservation management server device 20 updates the conference reservation information 21-a based on the contents of this operation.

  Next, each information stored in the database 21 in the reservation management server apparatus 20 will be described with reference to the drawings.

  First, referring to FIG. 5, the conference reservation information 21-a, which is a table for storing information related to conference room reservation, includes “conference room”, “phone number”, “reservation person”, “use start date / time”, “ "Use end date", "Use status" and "Unused state duration" are included as attributes.

  The conference reservation information 21-a stores one line of information for one reservation.

  Here, the “conference room” stores information for identifying the conference room 40 to be reserved.

  Further, the “telephone number” stores a telephone number assigned to the telephone 30 installed in the conference room 40 to be reserved.

  Furthermore, information for identifying a user who made a reservation using the user terminal 50 is stored in the “reservation person”.

  Furthermore, the “use start date and time” stores the reservation start time, that is, the time to start using the conference room 40 that is the reservation target.

  Further, the “use end date and time” stores the end time of the reservation, that is, the time to end the use of the conference room 40 that is the target of the reservation.

  Furthermore, in “Usage status”, information indicating whether the conference room 40 to be reserved is being used by the user or in an unused state is stored.

  Further, the “unused state duration” stores information indicating how long the reserved conference room 40 has been unused.

  Among these, the contents stored in “conference room”, “telephone number”, “reservation person”, “use start date / time” and “use end date / time” are input by the user terminal 50 by the user when making a reservation. Content.

  On the other hand, the contents stored in the “usage status” and “unused state duration” are based on the usage status of the conference room 40 acquired by the private branch exchange 10.

  Specifically, the reservation management server device 20 is notified of the usage status of the conference room 40 acquired by the private branch exchange 10. The reservation management server device 20 that has received the notification updates the conference reservation information 21-a by storing the notified use status of the conference room 40 in the conference reservation information 21-a. For example, when the notification content indicates that the user is present in the conference room 40, “in use” is stored in the “usage status” of the conference reservation information 21-a. On the other hand, when the notification content indicates that the user is not present in the conference room 40, the “usage status” of the conference reservation information 21-a is “unused”. In this way, the reservation management server device 20 stores the latest conference room usage status in the conference reservation information 21-a.

  In the drawing, for convenience of explanation, words such as “first conference room” and “Sato” are used in the conference reservation information 21-a, but in actuality, “first conference room” is identified. ID for identifying or “Sato” may be stored.

  Next, the timer information 21-b will be described with reference to FIG. Here, the timer information 21-b includes a usage status confirmation interval timer value and a sound analysis processing timer value.

  First, the usage status confirmation interval timer value will be described. As described above, in the present embodiment, the private branch exchange 10 determines the usage status of the conference room 40 using each telephone 30. Such determination is preferably performed periodically. This is because, even if it is determined that the conference room 40 is not in use, it is necessary to determine that the conference room 40 has been used if the conference is started later. It is.

  Therefore, in this embodiment, a predetermined period is set as the usage status confirmation interval timer value. When the date and time stored in the “use start date and time” included in the conference reservation information 21-a is reached, the usage status of the conference room 40 is determined using each telephone 30. In addition, the private branch exchange 10 repeatedly uses the telephones 30 to determine the usage status of the conference room 40 every time a predetermined period set as the usage status confirmation interval timer value elapses.

  In the example shown in FIG. 6, the length of the predetermined period is “5 minutes”, but this is merely an example, and the length of the predetermined period set as the usage status confirmation interval timer value Can be of any length depending on the environment in which this embodiment is implemented.

  Next, the sound analysis processing timer value will be described. As described above, in this embodiment, when determining the usage status of the conference room 40, the private branch exchange 10 analyzes the sound in the conference room 40 around each telephone 30 that the telephone 30 listens to. However, it is not necessary to continue listening by each telephone 30 longer than necessary. In addition, if there is a limit on the number of lines that can be talked at the same time in the present embodiment, if the line is continuously used to determine the usage status, the number of lines will be reduced even if a call is made for other purposes. There will be a situation where there is a shortage.

  Therefore, in this embodiment, a predetermined period is set as the sound analysis processing timer value. Then, the listening by each telephone 30 is continued from the start of listening by each telephone 30 until the elapse of a predetermined period set as the sound analysis processing timer value. Thereby, after the elapse of a predetermined period set as the sound analysis processing timer value, the line is released, and the line can be used for other purposes.

  In the example shown in FIG. 6, the length of the predetermined period set as the sound analysis processing timer value is “1 minute”, but this is merely an example, and the length of the predetermined period is The length can be set arbitrarily according to the environment in which the present embodiment is mounted.

  After detecting the user's voice and determining that the conference room 40 is in use, it is not necessary to continue listening by each telephone 30. Therefore, if it can be determined that the conference room 40 is in use, listening to each telephone 30 may be canceled even before a predetermined period set as the sound analysis processing timer value has elapsed. good.

  Next, with reference to the sequence diagram of FIG. 7, an operation for determining the usage status of the conference room 40 reserved in the present embodiment will be described. In the following description, it is assumed that a reservation is made for the first conference room 40-1. Therefore, in the following description, in order to determine the usage status of the first conference room 40-1, processing is performed on the first telephone 30-1 installed in the first conference room 40-1. . The contents of the processing are the same when processing is performed on the other telephones 30.

  The reservation management server device side control unit 22 of the reservation management server device 20 refers to the conference reservation information 21-a stored in the database 21 and confirms whether or not there is a conference room 40 that has been reserved. As described above, a reservation is made for the first conference room 40-1. Therefore, the reservation management server apparatus side control part 22 acquires the telephone number of the 1st telephone 30-1 installed in the 1st conference room 40-1 stored in the conference reservation information 21-a. In this example, the telephone number “XX1” is acquired. Furthermore, the reservation management server apparatus side control part 22 waits until the use start date in the reservation about the 1st conference room 40-1.

  Then, when the use start date / time is reached, the reservation management server side control unit 22 makes a call request to the private branch exchange 10 to the telephone 30 to which the telephone number “XX1” is assigned (step S101). Note that this time, the processing when the use start date and time is reached is described. However, in the present embodiment, the same processing is periodically performed based not only on the use start date and time but also on the use status confirmation interval timer value. For example, if the predetermined period set as the usage status confirmation interval timer value is 5 minutes, the same processing is performed at intervals of 5 minutes even after the usage start date and time is reached.

  Next, the private branch exchange 10 confirms the state of the first telephone 30-1 that is the telephone 30 to which the telephone number “XX1” is assigned (step S103).

  As a result of the confirmation in step S103, when the first telephone 30-1 is busy (in a call or in a state of calling) (Yes in step S103), the private branch exchange 10 is in the first conference room 40-1. It is determined that the user is in the room. Then, the private branch exchange 10 notifies the reservation management server device 20 that the usage status of the first conference room 40-1 is “in use” (step S113).

  The reservation management server device 20 that has received the notification updates the content of “usage status” for the first conference room 40-1 of the conference reservation information 21-a to “in use” based on the notification (step S115). ).

  This ends the current process. However, as described above, the same processing is periodically performed based on the usage status confirmation interval timer value thereafter.

  Here, the reason why the first meeting room 40-1 is periodically used in spite of the fact that the first meeting room 40-1 is being used will be described.

  If the conference room 40 to be determined is being used, other users cannot use the conference room 40. Therefore, after that, it may be considered not to perform the process of determining the usage status. However, for example, when the conference ends earlier than scheduled, the conference room 40 can be used by another user thereafter. Therefore, it is meaningful to determine that the conference has ended earlier than scheduled and the conference room 40 has not been used. Therefore, in consideration of this point, even if it is found that the first conference room 40-1 is being used, the process for determining the usage status is periodically performed thereafter. May be. It should be noted that the case where the conference ends earlier than scheduled is a state where the conference room 40 has been used once, and is not strictly “unused”. Therefore, the conference room 40 whose “use status” is no longer in use due to the meeting being ended earlier than scheduled may be managed as being “used” instead of “unused”.

  On the other hand, if the result of the confirmation in step S103 is that the first telephone 30-1 is in an idle state (a state in which neither a call nor a call is being made) (No in step S103), the private branch exchange 10 has the first conference room 40- It is determined that the user may not be in the room.

  Therefore, the private branch exchange 10 makes a call to the first telephone 30-1 to confirm whether or not the user is present in the first conference room 40-1 (step S105).

  The telephone function unit 32 of the first telephone 30-1 automatically responds to this call (step S107). Thereby, a call path is established between the private branch exchange 10 and the microphone 33 of the first telephone 30-1 (corresponding to reference numeral 201 in FIG. 7).

  In addition, accompanying the automatic response, the microphone 33 transitions to a state in which the sound around the first telephone 30-1 is different from that during a normal call (corresponding to reference numeral 202 in FIG. 7). For example, while listening to sound from the microphone 33 using a function that is in a so-called hands-free mode, the function of the speaker 35 is turned off, so that the output from the speaker is not performed. By doing so, the user's meeting in the first meeting room 40-1 is not hindered. In addition, it is not necessary for the user who has a meeting in the first meeting room 40-1 to interrupt the meeting and perform some operation. Then, the sound heard by the microphone 33 is transmitted to the private branch exchange 10 through the established call path (corresponding to reference numeral 201 in FIG. 7).

  On the other hand, the private branch exchange 10 obtains the sound heard by the microphone 33 through the established call path (corresponding to reference numeral 201 in FIG. 7). Then, the sound detection unit 14 detects a sound, and the sound analysis unit 15 transitions to a state in which processing for analyzing whether the sound detected by the sound detection unit 14 is a human voice (in FIG. 7). Equivalent to reference numeral 203).

  The sound detection unit 14 and the voice analysis unit 15 of the private branch exchange 10 are in such a state (reference numeral 203 in FIG. 7) until the period set as the sound analysis processing timer value included in the timer information 21-b elapses. Equivalent). For example, if 1 minute is set as the sound analysis processing timer value as shown in FIG. 6, this state is kept for 1 minute after the transition to this state (corresponding to reference numeral 203 in FIG. 7). (Corresponding to reference numeral 203 in FIG. 7) is continued.

  When the voice analysis unit 15 analyzes and detects the voice of the person in the first conference room 40-1 until the period set as the sound analysis processing timer value elapses, the first It can be determined that the conference room 40-1 is in use. In this case, it is not necessary to listen to the sound of the first conference room 40-1 or to analyze the sound. Therefore, in this case, the call is disconnected without waiting for the period set as the sound analysis processing timer value to elapse (step S11). Then, the private branch exchange 10 notifies the reservation management server device 20 that the usage status of the first conference room 40-1 is “in use” (step S113).

  The reservation management server device 20 that has received the notification updates the content of “usage status” for the first conference room 40-1 of the conference reservation information 21-a to “in use” based on the notification (step S115). ).

  This ends the current process. However, as described above, the same processing is periodically performed based on the usage status confirmation interval timer value thereafter.

  On the other hand, when the voice analysis unit 15 analyzes and does not detect the voice of the person in the first conference room 40-1 until the period set as the sound analysis processing timer value elapses It can be determined that the first conference room 40-1 is unused. In this case, when the period set as the sound analysis processing timer value elapses, the call is disconnected (step S111). Then, the private branch exchange 10 notifies the reservation management server device 20 that the usage status of the first conference room 40-1 is “unused” (step S113).

  The reservation management server device 20 that has received the notification updates the content of “usage status” for the first conference room 40-1 of the conference reservation information 21-a to “unused” based on the notification (step S115). ).

  In addition, as described above, the conference reservation information 21-a includes “unused state duration” as an attribute. In each of the periodically repeated processes, a predetermined period set as a usage status confirmation interval timer value every time notification that the usage status of the first conference room 40-1 is “unused” Is added to the “unused state duration” for 5 minutes. For example, as shown in FIG. 6, when the usage status confirmation interval timer value is 5 minutes, when the first conference room 40-1 is received “not used” six times, one conference room 40 “30 minutes” is stored in the “unused state duration” for -1.

  This ends the current process. However, as described above, the same processing is periodically performed based on the usage status confirmation interval timer value thereafter.

  The operation described above is performed for all reservations. Thereby, the conference reservation information 21-a stored in the database 21 of the reservation management server device 20 indicates the latest usage status of each conference room 40.

  Thereby, the user who wants to use any one of the conference rooms 40 refers to the conference reservation information 21-a stored in the database 21 of the reservation management server device 20 at the user terminal 50 for the usage status of each conference room 40. The effect that it becomes possible to confirm by this is produced. Specifically, it is possible to check not only whether each conference room 40 is being used or unused, but also how long it has been unused if not used.

  Thereby, the user can specify the conference room 40 in which the unused state continues for a long time. Further, by referring to the conference reservation information 21-a, it is possible to specify who is the reservation person who reserved the conference room 40 that has been unused for a long time. Therefore, the user can confirm whether or not the conference room 40 can be used by calling the reservation person.

  The present embodiment has been described above.

  Here, if this embodiment is not used, when a user wants to find and use an empty conference room, the user goes to the conference room and listens carefully from outside the conference room to see the inside of the conference room. Therefore, it is necessary for the user to determine whether or not it is free.

  However, in this embodiment, the user can confirm the usage status of each conference room 40 by referring to the conference reservation information 21-a at the user terminal 50 at hand. Therefore, it is not necessary for the user to go to the conference room or listen to the inside of the conference room.

  Further, in the reservation management system disclosed in Patent Document 1, it is necessary to respond to the telephone in order to reflect the use status of the conference room in the system. As a result, users participating in the conference had to interrupt the conference. In other words, the reservation management system described in Patent Document 1 is a mechanism in which the system positively enforces a confirmation operation when a conference room is empty or in use, in order for the system to reliably perform management. Further, the confirmation operation must be performed even when there is no user who wants to use the conference room other than the reservation person, which is inconvenient for the user.

  On the other hand, in the present embodiment, the devices included in the present embodiment secretly and automatically search for the usage status of the conference room and manage the results. That is, the user does not need a special operation for completely managing the vacant conference room, and does not cause trouble. In this embodiment, the user performs the operation to search for a vacant conference room. Only.

  That is, in this embodiment, it is not necessary for the user who is holding the conference to interrupt the conference and perform the operation, and it can be said that the user is excellent in convenience.

  Further, in Patent Document 2, it is necessary to prepare a dedicated terminal including a sensor for detecting whether a user is present or not and a presence detection unit. However, in this embodiment, since a telephone set generally installed in a conference room can be used, it is not necessary to prepare such a dedicated terminal. That is, the embodiment can be realized at low cost by using existing equipment.

<Modification>
Next, two modified examples obtained by modifying the above-described embodiment will be described.

  First, a first modification will be described. As described above, according to the present embodiment, if the conference room 40 is vacant, a user who uses the conference room 40 (hereinafter referred to as “user who wants to use”) makes a conference reservation at the user terminal 50 at hand. The use status of each conference room 40 can be confirmed by referring to the information 21-a.

  However, even if the reservation person who made the reservation does not currently use the conference room and the current use status is “unused”, the reservation person can use the conference room 40 that has been reserved after that. There is sex. Therefore, even if the current usage status is “unused”, the user who wants to use makes a call to the reservation person by telephone, and the current usage status is “unused” in a call using the telephone. It is desirable to confirm whether or not the conference room 40 can be used.

  Therefore, in the present modification, the private branch exchange 10 that has confirmed the usage status of the conference room 40, in addition to the notification of the usage status of the conference room 40 to the reservation management server device 20 performed in step S113 described above. Then, notification is made to the telephone of the user who wants to use.

  Then, the user who wants to use can check the notification contents on the display unit of the phone of the user who wants to use. Furthermore, the user who wishes to use can make a call to the telephone of the reservation person in the conference room 40 whose current usage status is “unused” based on the notification content.

  That is, the user who wants to use can perform a series of operations such as confirmation on the display of the telephone and a call for confirmation from the telephone with a single telephone at his / her desk. In this modification, the user convenience can be improved in this way.

  First, the configuration of this modification will be described with reference to FIG. Referring to FIG. 8, in this modification, in addition to the configuration shown in FIG.

  Here, the user-desired user telephone 70 is a telephone used by a user who wishes to use. On the other hand, the reservation person telephone 80 is a telephone used by a reservation person who has made a reservation for any conference room 40. In the following description, as an example, it is assumed that the reservation person who made a reservation for the first conference room 40-1 uses the reservation person telephone 80.

  The user telephone 70 and the subscriber telephone 80 that are desired to use can communicate with each other via the private branch exchange 10. Further, the user telephone 70 and the reservation person telephone 80 that are desired to use can communicate with each telephone 30 via the private branch exchange 10.

  It is assumed that a unique extension telephone number and an external telephone number are assigned to the user telephone 70 and the reservation telephone 80, respectively. Specifically, it is assumed that the telephone number “X70” is assigned to the user telephone 70 that desires use. In addition, it is assumed that the telephone number “X80” is assigned to the reservation person telephone 80.

  Furthermore, it is assumed that the user telephone 70 and the reservation person telephone 80 that are desired to use include the same functional blocks as the telephones 30. Note that the functional blocks included in each telephone 30 have been described above with reference to FIG.

  In addition, since each device other than the use-desired user telephone 70 and the reservation subscriber telephone 80 is the same as that in the above-described embodiment, the re-explanation for these devices is also omitted.

  Next, the operation of this modification will be described with reference to the flowchart of FIG.

  First, the processing from step S101 to step S115 is executed. Since this processing is the same as that described above with reference to FIG. 7, the description thereof will be omitted.

  Next, in order to confirm whether or not there is an unused conference room 40 by the user who wants to use, information about the unused conference room 40 is inquired to the private branch exchange 10 using the user phone 70 that wants to use (Step). S117). For the inquiry, for example, a button such as “inquiry for unused conference room” is provided on the user telephone 70 that desires use. Then, the user-desired user telephone 70 makes an inquiry in step S117 to the private branch exchange 10 when the user-desired user presses the button.

  In response to this inquiry, the private branch exchange 10 transmits information related to the unused conference room 40 to the user telephone 70 that desires use (step S119). Specifically, information such as a room number representing the conference room 40 in which the usage status of the conference room is “unused” is transmitted.

  Note that information equivalent to the conference reservation information 21-a shown in FIG. 5 is stored in the private branch exchange 10 for transmission. Or, when the private branch exchange 10 accepts the inquiry in step S117, the reservation management server apparatus 20 is inquired about the contents of the conference reservation information 21-a shown in FIG.

  The user-desired user telephone 70 that has received the information representing the conference room 40 whose usage status of the conference room is “unused” outputs the contents of the information so that the user who wants to use can grasp it. For example, the content of the information is displayed on the display unit of the user telephone 70 that desires use (step S121).

  The user who wishes to refer to this can grasp which conference room 40 is at least the conference room 40 in which the usage status of the conference room is “unused”.

  Next, the subsequent operation will be described with reference to FIG. The user who wishes to use referring to the display in step S121 confirms the sound of the conference room 40 in which the conference room usage status is “unused”, so that the conference room usage status is “unused”. An outgoing call operation is performed on the conference room 40. For example, a button such as “listen” is provided on the user telephone 70 that desires use. Then, the user-desired user telephone 70 makes a call to the telephone 30 installed in the conference room 40 in which the utilization status of the conference room is “unused” in response to the user pressing the button. This is performed (step S131).

  Such a call may be realized, for example, by specifying the room number of the conference room 40 that is the call destination based on information such as the room number transmitted in step S119. Then, the private branch exchange 10 that has received such a call may make a call to the telephone 30 installed in the conference room 40 corresponding to the specified room number. Instead, in step S119, the telephone number of the telephone set 30 installed in the conference room 40 in which the conference room usage status is “unused” is transmitted. The user-desired user telephone 70 transmits the telephone number, and the private branch exchange 10 that has received the telephone number may make a call to the telephone 30 corresponding to the telephone number.

  This time, it is assumed that a call is made to the first telephone 30-1 installed in the first conference room 40-1.

  When there are a plurality of conference rooms 40 in which the usage status of the conference room is “unused”, a desired call destination conference room 40 can be selected with an up / down button or the like.

  The private branch exchange 10 that has received a call from the user telephone 70 that wants to use makes a call to the first telephone 30-1 (step S133).

  The telephone function unit 32 of the first telephone 30-1 automatically responds to this call (step S135). Thereafter, the private branch exchange 10 performs a process for establishing a call path, whereby a call path is established between the user telephone 70 and the first telephone 30-1 that are desired to use (corresponding to reference numeral 201 in FIG. 7).

  In addition, with the automatic response, the first telephone 30-1 transitions to a state in which sound around the first telephone 30-1 that is different from that during a normal call is heard. For example, a sound is heard from the microphone 33 using a function of a so-called hands-free mode. By doing so, the user's meeting in the first meeting room 40-1 is not hindered. In addition, it is not necessary for the user who is conducting the conference in the first conference room 40-1 to interrupt the conference and perform any operation, and the sound heard by the microphone 33 is the established call path (see FIG. 7 (corresponding to reference numeral 201 in FIG. 7) is transmitted to the user telephone 70 that desires use (step S137). The transmitted sound is output from the speaker of the user telephone 70 desired to be used or the handset connected to the user telephone 70 desired to be used, so that the user who wishes to use has a meeting in the first conference room 40-1. It is possible to determine whether or not a person is present in the first conference room 40-1.

  As described above, the user in the conference room 40 is not aware that the telephone 30 collects sound for the purpose of determining the usage status of the conference room 40, and the conference room 40 You have a regular meeting with other users in the group. For this reason, the content of the conversation may include information that should be kept secret outside the conference. Therefore, processing such as applying a predetermined filter to the sound heard by the microphone 33 may be performed based on the viewpoint of enhancing the confidentiality of the conference content. Thereby, it is possible to prevent a user who wishes to use from hearing the specific content of the conversation in the conference room 40.

  It is also possible to allow the user who wants to use the voice to the first telephone 30-1 for confirmation.

  For example, a button such as “Voice” is provided on the user telephone 70 that desires use. Then, the user-desired user telephone 70 transmits the user-desired user's voice to the private branch exchange 10 to the first telephone 30-1 when the user-desired user presses the button (step S139). .

  Then, the received first telephone 30-1 may output the voice received from the user telephone 70 that desires use using a speaker, for example, using a hands-free call function. That is, it is preferable that the user who wants to use can directly talk to the person in the first conference room 40-1 from the user telephone 70 that wants to use. Further, if there is a person in the first conference room 40-1, it is preferable that the first telephone 30-1 can make a reply to the user wishing use telephone 70 about the voice call. As a result, the user who wishes to use can check the usage status of the conference room 40 more reliably.

  Further, the user who wants to use the user who refers to the display in step S121 makes a call to the reservation person telephone 80 used by the reservation person who made a reservation for the meeting room 40 in which the use state of the meeting room is “unused”. It is good to be able to do. For this purpose, as a premise, the reservation management server device 20 accepts the telephone number of the reservation person telephone 80 used by the reservation person when receiving the reservation from the reservation person. Then, the telephone number of the accepted reservation person telephone 80 is included in the conference reservation information 21-a. By doing in this way, the private branch exchange 10 and the reservation management server device 20 can grasp the telephone number of the reservation person telephone 80 used by the reservation person who made each reservation.

  Further, for example, a button such as “call to reservation person” is provided on the user telephone 70 that desires use. Then, in step S121, the use-desired user telephone 70 is triggered by the use-desiring user who has referred to the information representing the conference room 40 in which the use status of the conference room is “unused” pressing the button. A call is made to the reservation telephone 80 via the private branch exchange 10.

  Such a call may be realized, for example, by specifying the room number of the conference room 40 that is the call destination based on information such as the room number transmitted in step S119. Then, the private branch exchange 10 that has received such a call may make a call to the reservation person telephone 80 of the reservation person who has made a reservation for the conference room 40 corresponding to the specified room number. Instead, in step S119, the telephone number of the reservation person telephone 80 of the reservation person who made a reservation for the meeting room 40 whose utilization state of the meeting room is “unused” is transmitted. Then, the user telephone 70 desiring to use transmits the telephone number, and the private branch exchange 10 that has received the telephone number may make a call to the reservation telephone 80 corresponding to the telephone number. Note that the operation of each device when the private branch exchange 10 accepting a call from the user telephone 70 that wants to use makes a call to the reservation subscriber telephone 80 is a general process, so the sequence diagram is referred to. Description is omitted.

  The reservation person who uses the reservation person telephone 80 that has accepted the call from the user telephone 70 that wants to use can respond to the call and can have a conversation with the user who wants to use the telephone. As a result, the user who wishes to use can directly confirm with the reservation person whether or not the conference room 40 is actually used, so that it becomes possible to more reliably search for a vacant conference room 40.

  In the present modification described above, a user who wishes to use can perform a series of processes by operating the user wishing user telephone 70. Thereby, it becomes possible to improve a user's convenience. That is, in this modification, it is possible to search for a vacant room with a minimum telephone operation without causing trouble to the person in the meeting.

  Next, a second modified example obtained by modifying the above-described embodiment will be described. In the above-described embodiment, the private branch exchange 10 performs a series of processes for confirming the usage status of the conference room 40 for which a reservation has been made, in response to a transmission request from the reservation management server device 20 (step S101). (Corresponding to the processing after step S103).

  However, in this modification, the telephone number of the conference room 40 is registered in advance in the private branch exchange 10 instead of doing this. Then, the private branch exchange 10 spontaneously performs the processes after step S103 without questioning whether or not there is a transmission request from the reservation management server device 20. In this case, step S113 and step S115 may be omitted.

  Then, as described with reference to FIG. 9, when there is a request from the user telephone 70 that desires use in step S117, the private branch exchange 10 stores information on the conference room 40 whose use status is “unused”. The message is transmitted to the user telephone 70 that desires use (step S119).

  The user-desired user telephone 70 that has received the information representing the conference room 40 whose usage status of the conference room is “unused” outputs the contents of the information so that the user who wants to use can grasp it. For example, the content of the information is displayed on the display unit of the user telephone 70 that desires use (step S121).

  The user who wishes to refer to this can grasp which conference room 40 is at least the conference room 40 in which the usage status of the conference room is “unused”.

  By doing in this way, in this modification, it becomes possible to show the same effect as the above-mentioned embodiment, even if the reservation management server device 20 and the private branch exchange 10 do not cooperate with the signal level.

  In addition, the above-described embodiment and each modification are preferred embodiments and each modification of the present invention, but the scope of the present invention is not limited to the above-described embodiment and each modification. Implementation in various forms without departing from the gist is possible.

  For example, it is conceivable that the user of the conference room 40 uses the telephone 30 installed in the conference room 40 while listening to sound with the microphone 33 after establishing the call path in step S107. For example, it is conceivable to make a call to another telephone using the telephone 30. In this case, listening to the telephone 30 is stopped, and the private branch exchange 10 makes a call to another telephone. At the same time, the private branch exchange 10 determines that the usage status of the conference room 40 in which the telephone 30 is installed is “in use”, and transmits that fact to the reservation management server device 20. Then, the reservation management server device 20 reflects the usage status in the conference reservation information 21-a. As a result, the conference reservation information 21-a can be updated to the latest state, and the user of the conference room 40 can use the telephone 30 installed in the conference room 40.

  1 and 8 show a case where there is only one user terminal 50, a plurality of user terminals 50 may be provided. Thereby, the user can make a reservation for a conference room using an arbitrary user terminal 50. Furthermore, the number of the conference room 40 in which the reservation management server device 20 manages reservations and the number of telephones 30 installed in the conference room 40 can be set to an arbitrary number.

  Further, the user terminal 50 may be installed in any conference room 40. The user terminal 50 may be a wireless terminal that is carried by the user.

  Moreover, although it demonstrated using the wording of the meeting room 40 in the above, a meeting room is only an example and there is no limitation in particular in the use of each room. Instead of a conference room, it may be a room for other purposes. Further, it may be a predetermined area instead of a room. That is, it may be a predetermined place where the telephone 30 is installed.

  Each device included in the occupancy status management system can be realized by hardware, software, or a combination thereof. The occupancy status management method performed by each device included in the occupancy status management system can also be realized by hardware, software, or a combination thereof. Here, “realized by software” means realized by a computer reading and executing a program.

  The program may be stored using various types of non-transitory computer readable media and supplied to the computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD- R, CD-R / W, and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)).

  The embodiment of the present invention described above has many effects as described below.

  The first effect is that telephone operations during the conference can be eliminated. The reason is that the telephone set in the conference room automatically answers and listens to the audio of the conference room with a microphone, so that it can be determined whether or not the user is in the conference room. This is because the user who wants to use can easily determine the usage status of the conference room.

  The second effect is that the conference room reservation management function can be provided at low cost. The reason is that it is not necessary to prepare a new sensor or the like by using an existing private branch exchange and a telephone. Furthermore, a system can be constructed at a lower cost by integrating the private branch exchange and the reservation management server device.

  The third effect is that an area that is not managed by the reservation management server device (for example, free space) or occupancy management when a conference room is used without making a reservation is also possible. The reason is that it is possible to determine whether or not the user is present if a telephone is provided even in an area where there is no reservation management server device.
