Description

  The present invention relates to a use status management apparatus, a use status management system, a use status management method, and a use status management program for managing the use 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, the general reservation management system only manages the reservation status made based on the user's operation, and manages whether the meeting room, the reception room, etc. are actually used as the reservation. I did not.

  Therefore, even if there is a conference room reserved but not actually used, users other than those who wish to use this conference room can easily determine the availability of the conference room. There wasn't.

  As a result, even though the meeting room is available, the user who wants to use the meeting room can not use the meeting room, and the meeting room can not be used efficiently.

  Patent Literatures 1 and 2 disclose an example of a technique for promoting efficient use of a conference room in consideration of such a situation.

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

  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 device described in Patent Document 1 manages the actual room availability of the conference room by confirming the presence or absence of the response from the reservation person using the 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, this method can not accurately determine whether the user is present in the conference room if the user has left the terminal in his / her seat or the like. Therefore, according to Patent Document 2, a conference room terminal in which a sensor is mounted is further installed in a conference room, and by using the conference room terminal, whether the user is present in the conference room or not, etc. 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 a change in the environment of the conference room are mounted. Then, based on the contents of the change in the environment of the conference room detected by the sensor, each conference room terminal determines whether the user is present in the conference room.

  Furthermore, in this embodiment, it is not necessary to provide a detection unit for determining whether or not the user is present in the conference room on the telephone set installed in the conference room or the like.

  The above is the outline of the present embodiment.

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

  First, FIG. 1 is a block diagram showing the whole structure of the occupancy status management system 1 which is embodiment of this invention.

  Referring to FIG. 1, the occupancy 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 n-th conference room 40-n are called collectively or without specifying any of them, Call it 40 ".

  In addition, the first telephone 30-1, the second telephone 30-2, and the nth telephone 30-n, which are a plurality of telephones 30, are each a separate meeting room. , And 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 at the end of the code.

  Furthermore, it is assumed that each telephone set 30 is assigned a unique extension or extension telephone number. Specifically, it is assumed that a 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 a telephone number "XXn" is assigned to the nth telephone set 30-n.

  The private branch exchange 10 and the reservation management server device 20 are connected so as to communicate with each other. Furthermore, the private branch exchange 10 is connected to the telephones 30 installed in each conference room 40. Furthermore, 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 control unit 12 can be realized by, for example, an arithmetic processing unit such as a CPU (Central Processing Unit) and a storage device. 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 control unit 12 controls hardware included in the private branch exchange 10 based on the result of the arithmetic processing. That is, 10 can be realized by the cooperation of hardware and software.

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

  The sound detection unit 14 and the voice analysis unit 15 are portions for determining the use situation of the conference room 40. The sound detection unit 14 and the voice analysis unit 15 analyze the sound in the conference room listened from the microphone of the telephone set 30 managed by the private branch exchange 10, and determine the use situation of the conference room 40 based on the analysis result.

  Specifically, call control unit 11 is provided in each conference room 40 for which a reservation has been made with reference to information (details will be described later) indicating the reservation status of each conference room 40 managed by private branch exchange 10. The telephone number of each designated telephone 30 is acquired. 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. The sound detected from the microphone of the telephone set 30 is detected by the sound detection unit 14. Then, 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 considered to be human voice is included, it is determined that a person is present in the conference room 40. Also, for example, when a sound of a certain size is included, it is considered that this is a sound generated along with the operation of the person in the room. 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 the user who is present in the conference room 40 is not aware of the fact that voice is being collected by the telephone 30 for the purpose of determining the use situation of the conference room 40, and other users in the conference room 40 We have meetings as usual. Therefore, the content of the conversation may include information to be concealed outside the meeting place. 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 determine The determination result is output to the exchange control unit 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 website 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, "meeting reservation information 21-a", which is information related to reservation of a meeting room, and "timer information 21-b", which is information related to a timer used when monitoring the meeting room. The Details of these pieces of information will be described later with reference to FIGS. Further, these pieces of information are updated to the latest contents by the reservation management server apparatus side control unit 22.

  The reservation management server apparatus side control unit 22 is an arithmetic processing unit for controlling the entire private branch exchange 10. The reservation management server device side control unit 22 can be realized by, for example, an arithmetic processing unit such as a CPU (Central Processing Unit) and a storage device, as the exchange side control unit 12 does. Then, the reservation management server apparatus side control unit 22 reads software stored in the above-described database 21 or a storage unit or the like (not shown), and performs arithmetic processing based on this 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 web site generation unit 23 is a part that generates a web site for the user to view the usage status of the conference room. The website generation unit 23 generates a website based on each piece of information stored in the database 21. The web site is a site for displaying, for example, a reservation table representing each information stored in the database 21. The website also provides a user interface for the user to make a reservation, the user to change the reservation, and the user to cancel the reservation.

  Next, referring to FIG. 3, the telephone set 30 includes a display unit 31, a telephone function unit 32, a microphone 33, an operation receiving 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, a 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 the 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 to make 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, switching of display information, or the like. 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. The display unit 31 and the operation reception 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 accepting unit 34 may be unique to the present embodiment, but may be a speaker provided in a normal telephone so as to make a so-called hands-free call.

  Although a handset is generally connected to the telephone 30, the handset is not shown because it is considered that it is not directly related to the subject matter 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 device 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 on conference room reservations, includes "conference room", "telephone number", "reserved person", "use start date and 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 “meeting room” stores information for identifying the meeting room 40 which is the target of reservation.

  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 has made a reservation using the user terminal 50 is stored in the “reserved 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, the “use status” stores information indicating whether the meeting room 40 which is the target of the reservation is in use by the user or is not in use.

  Further, in the “non-used state continuation time”, information indicating how long the non-used state of the meeting room 40 which is the target of reservation is continued is stored.

  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 the “non-used state continuation time” are contents based on the use 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 usage condition 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 meeting room 40, “in use” is stored in the “use status” of the meeting reservation information 21-a. On the other hand, when the notification content indicates that the user is not present in the meeting room 40, the "use status" of the meeting reservation information 21-a is "unused". In this way, the reservation management server device 20 stores the latest meeting room use status in the meeting reservation information 21-a.

  In the drawing, the words “first meeting room”, “Sato”, etc. are used in the meeting reservation information 21-a for convenience of explanation, but in reality, “first meeting room” is identified An ID for performing the process or an ID for identifying "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 use 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 use status of the conference room 40 using each telephone set 30. Such determination is preferably performed periodically. Because, even if it is determined that the meeting room 40 has not been used once, if the meeting is started later, it is necessary to determine that the meeting room 40 is in use. It is.

  Therefore, in this embodiment, a predetermined period is set as the usage status confirmation interval timer value. Then, when the date and time stored in the “use start date and time” included in the meeting reservation information 21-a comes, the use 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 the present embodiment, when determining the use status of the conference room 40, the private branch exchange 10 analyzes the sound in the conference room 40 around each of the telephones 30 that each of the telephones 30 has listened 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, after the start of the listening by each of the telephones 30, the listening by each of the telephones 30 is continued until the predetermined period set as the sound analysis processing timer value elapses. Thus, after the predetermined period set as the sound analysis processing timer value has elapsed, the line is opened, and the line can be used in other applications.

  In the example shown in FIG. 6, the length of the predetermined period set as the sound analysis processing timer value is “one 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.

  It is not necessary to continue listening by each telephone 30 after detecting the voice of the user and determining that the conference room 40 is in use. Therefore, if it can be determined that the conference room 40 is in use, even if the predetermined time set as the sound analysis processing timer value has not elapsed, the listening by each telephone set 30 may be stopped. good.

  Next, with reference to the sequence diagram of FIG. 7, the operation at the time of determining the use 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 unit 22 acquires the telephone number of the first telephone set 30-1 installed in the first meeting room 40-1, which is stored in the meeting 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 and time comes, the reservation management server apparatus side control unit 22 requests the private branch exchange 10 to make a call to the telephone set 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 5-minute intervals even after the usage start date and time has come.

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

  As a result of the confirmation in step S103, if the first telephone set 30-1 is in the busy state (in a call or in a calling state) (Yes in step S103), the private branch exchange 10 enters 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 use 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 the “usage status” of the first meeting room 40-1 of the meeting 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, although the first conference room 40-1 is found to be in use, the reason for periodically performing the process of determining the use situation will be described.

  If the meeting room 40 targeted for the determination is in use, other users can not use the meeting room 40. Therefore, after that, it may be considered not to perform the process of determining the usage status. However, for example, if the meeting ends earlier than scheduled, then the meeting room 40 can be used by other users. Therefore, it is meaningful to determine that the meeting ends earlier than scheduled and the meeting room 40 is not in use. Therefore, in consideration of this point, even if it is determined that the first conference room 40-1 is being used, the process of determining the use situation is periodically performed thereafter. May be. In the case where the conference ends earlier than planned, the conference room 40 is in a state of being used once, and it 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, as a result of confirmation in step S103, if the first telephone set 30-1 is in the idle state (not in call or in call) (No in step S103), private branch exchange 10 selects the first conference room 40 It is determined that the user may not be in the room.

  Therefore, the private branch exchange 10 calls the first telephone 30-1 to check whether the user is present in the first conference room 40-1 (step S105).

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

  Further, in response to the automatic response, the microphone 33 changes to a state of listening to the sound around the first telephone 30-1 different from that during the normal call (corresponding to the code 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 this, the meeting of the users who are holding a meeting in the first meeting room 40-1 will not be disturbed. Moreover, there is no need for the user who is having a conference in the first conference room 40-1 to interrupt the conference and perform some operation. Then, the sound listened to by the microphone 33 is transmitted to the private branch exchange 10 via the established communication path (corresponding to the code 201 in FIG. 7).

  On the other hand, the private branch exchange 10 acquires the sound heard by the microphone 33 via the established call path (corresponding to the code 201 in FIG. 7). Then, the sound detection unit 14 detects a sound, and the voice analysis unit 15 performs a process of analyzing whether the sound detected by the sound detection unit 14 is a human voice (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 a person in the first conference room 40-1 before 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 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 use 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 the “usage status” of the first meeting room 40-1 of the meeting 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 the voice of the person in the first conference room 40-1 is not detected while 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 time set as the sound analysis processing timer value has elapsed, 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 the “usage status” of the first meeting room 40-1 of the meeting reservation information 21-a to “unused” based on the notification (step S115). ).

  Also, as described above, the meeting reservation information 21-a includes “unused state duration” as an attribute. Then, in each periodically repeated process, a predetermined period set as a use status check interval timer value every time it is notified that the use status of the first conference room 40-1 is "unused". Is added to "unused status continuation time" 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. As a result, 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 of the conference rooms 40 refers to the conference reservation information 21-a stored in the database 21 of the reservation management server apparatus 20 at the user terminal 50, regarding 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 meeting room 40 in which the non-use state continues for a long time. Further, by referring to the conference reservation information 21-a, it is possible to specify who is the person who reserved the reservation for the conference room 40 which has not been used for a long time. Therefore, the user can check whether the conference room 40 may be used by calling the reservation person or the like.

  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 the present embodiment, the user can confirm the use situation of each conference room 40 by referring to the conference reservation information 21-a with the user terminal 50 at hand. Therefore, it is not necessary for the user to look into the meeting room or to listen to the inside of the meeting room.

  Further, in the reservation management system in Patent Document 1, it is necessary to respond to the telephone in order to reflect the use situation of the conference room in the system. As a result, users participating in the conference had to interrupt the conference. In other words, in the reservation management system described in Patent Document 1, the system positively forces people to check the sky of the conference room and the check operation in use in order for the system to perform management reliably. Then, even when there is no user who wants to use the conference room other than the reservation person, the confirmation operation has to be performed, which is not convenient for the user.

  On the other hand, in the present embodiment, the devices included in the present embodiment secretly automatically search for the usage condition of the conference room and manage the result. In other words, the user does not need a special operation for completely managing an empty meeting room, and no trouble is generated. In this embodiment, the user who searches for an empty meeting room performs an operation. Only.

  That is, in the present embodiment, there is no need to interrupt the meeting for the user who is holding the meeting to perform the operation, and it can be said that the user has excellent convenience.

  Further, in Patent Document 2, it is necessary to prepare a dedicated terminal including a sensor for detecting whether or not the user is in the room and a room detection unit. However, in the present embodiment, since a telephone set generally installed in a conference room can be used, there is no need 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 this modification, the private branch exchange 10 having checked the use status of the conference room 40 adds to the notification of the use status of the conference room 40 to the reservation management server device 20 performed in the above-described step S113. , Notify the user of the desired user phone.

  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 desiring to use can make a call to the telephone of the reserver of the conference room 40 whose current use 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 the present modification will be described with reference to FIG. Referring to FIG. 8, in the present 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 reserver telephone 80 is a telephone used by a reserver who made a reservation in any of the conference rooms 40. In the following description, as an example, it is assumed that a reserver who has made a reservation for the first conference room 40-1 uses the reserver 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 telephone number of an extension or an outside line unique to each of the use desired user telephone 70 and the reserver telephone 80 is assigned. 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 use desired user telephone 70 and the reserver telephone 80 include functional blocks equivalent to the respective telephones 30. The functional blocks included in each of the telephones 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 check whether there is an unused meeting room 40 for the use request user, the private exchange 10 is inquired of information on the unused meeting room 40 using the use request user telephone 70 (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 the inquiry, the private branch exchange 10 transmits information on the unused conference room 40 to the use desired user telephone 70 (step S119). Specifically, information such as a room number indicating at least the conference room 40 in which the use status of the conference room is "unused" is transmitted.

  Note that, for transmission, information equivalent to the conference reservation information 21-a shown in FIG. 5 is stored inside the private branch exchange 10. 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 use desired user telephone 70 makes a call to the telephone 30 installed in the conference room 40 in which the use situation of the meeting room is "unused", triggered by the use desired 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 having received such a call may call the telephone set 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. Then, it is preferable that the use desired user telephone 70 transmit the telephone number and the private branch exchange 10 receiving the telephone number makes 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 the call from the use desired user telephone 70 calls 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 processing for establishing a call path, whereby a call path is established for the user telephone 70 desired for use and the first telephone 30-1 (corresponding to reference numeral 201 in FIG. 7).

  In addition, with the automatic response, the first telephone set 30-1 transitions to a state of listening to sounds around the first telephone set 30-1 different from during a normal call. For example, a sound is heard from the microphone 33 using a function of a so-called hands-free mode. By doing this, the meeting of the users who are holding a meeting in the first meeting room 40-1 will not be disturbed. Also, there is no need for the user who is having a conference in the first conference room 40-1 to interrupt the conference and perform any operation. The sound heard by the microphone 33 is the established communication path (see FIG. 7 (corresponding to reference numeral 201 in FIG. 7) is transmitted to the user telephone 70 that desires use (step S137). By outputting the transmitted sound from the speaker of the user phone 70 for use request and the handset connected to the user phone 70 for use user, the user wanting to use a conference is held 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. Therefore, the content of the conversation may include information to be concealed outside the meeting place. 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. This can prevent the user desiring to use from listening to the specific content of the conversation in the meeting 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 use desired user telephone 70 transmits the voice of the use desired user to the first telephone 30-1 to the private branch exchange 10 triggered by the use desired user pressing 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 use desired user can directly call the person in the first conference room 40-1 from the use desired user telephone 70. In addition, if there is a person in the first conference room 40-1, it is preferable that the first telephone 30-1 can make a response to the call request to the use desired user telephone 70. 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. To that end, as a premise, when the reservation management server device 20 receives a reservation from the reservation person, the telephone number of the reservation person's telephone 80 used by the reservation person is accepted. 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, the use wishing user telephone 70 is triggered by the use wishing user who refers to the information representing the meeting room 40 whose use state of the meeting room is "unused" in step S121 presses 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. Also, instead of doing so, the telephone number of the reserver telephone 80 of the reserver who made the reservation for the conference room 40 whose use status of the conference room is "unused" is transmitted in step S119. Then, the user telephone 70 may request that the user telephone 70 transmit the telephone number, and the private branch exchange 10 receiving the telephone number may make a call to the subscriber telephone 80 corresponding to the telephone number. Since the operation of each device when the private branch exchange 10 accepting the call origination of the use desired user telephone 70 makes a call to the reserver telephone 80 is a general process, the sequence diagram was 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, the user who wants to use can operate the user desired user telephone 70 to perform a series of processes. 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 embodiment described above, the private branch exchange 10 has performed a series of processes for confirming the use status of the conference room 40 for which the reservation has been made, in response to the transmission request (step S101) from the reservation management server device 20. (Corresponding to the processing after step S103).

  However, in this modification, instead of this, the telephone number of the conference room 40 is registered in advance in the private branch exchange 10. Then, the private branch exchange 10 voluntarily performs the processing after step S103 without asking whether 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, in step S117, when there is a request from the user phone 70 for which the user wishes to use, the private branch exchange 10 uses the information about the conference room 40 whose usage 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 so, in the present modification, even if the reservation management server device 20 and the private branch exchange 10 do not cooperate with each other in signal level, it is possible to obtain the same effect as the above embodiment.

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

  For example, after the call path is established in step S107, the user of the conference room 40 may use the telephone set 30 installed in the conference room 40 while listening to the sound with the microphone 33. For example, it is conceivable to make a call to another telephone using the telephone 30. In this case, the listening by the telephone set 30 is canceled and the private branch exchange 10 makes a call to another telephone set. 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.

  Moreover, although the case where only one user terminal 50 is shown is shown in FIG. 1 or 8, 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 of the devices included in the above room availability 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 programs can be stored and provided to a computer using various types of non-transitory computer readable media. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media are magnetic recording media (eg flexible disk, magnetic tape, hard disk drive), magneto-optical recording media (eg magneto-optical disk), CD-ROM (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 provided in the conference room automatically responds, and by listening to the voice of the conference room with the microphone, it can be determined whether the user is present in the conference room or not, and 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 by using the existing private branch exchange and telephone, it becomes unnecessary to newly prepare a sensor or the like. 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.
