Description

  The present invention relates to a private branch exchange system, and more particularly to a system for connecting a plurality of host computers to one private branch exchange.

  Conventionally, facilities that provide guest rooms such as hotels and inns, regardless of the size, install a private branch exchange in the facility and connect a host computer used for facility reservations etc. to this private branch exchange. In addition, it provides CRM (Customer Relationship Management) by the telephone system management of the guest rooms and the attendant console.

  As a connection method between such a private branch exchange and a host computer, for example, a method of connecting a private branch exchange and a host computer in a one-to-one relationship (for example, Patent Document 1), or a method of connecting in a plural-to-multiple manner (for example, Patent document 2) is generally used.

  For example, as shown in FIG. 7, the private branch exchange system 100 described in the cited document 1 includes a PBX (Private Branch eXchange) 101 having a CPU (Central Processing Unit) 110, a host computer 102, The terminal connecting device 103 accommodates and connects the telephones 104A and 104B.

  The PBX 101 is connected to the host computer 102 through a computer line 111 including a communication path 111a, a terminal control information path 111b, and a special data transmission path 111c. The PBX 101 is connected to the terminal connection apparatus 103 via the terminal line 112 including the communication path 112a and the control information path 112b.

  In the private branch exchange system 100, when the host computer 102 receives data from a terminal, the PBX 101 stores data received from the terminal via the terminal line 112 in the CPU 110. Then, the host computer 102 receives the calling terminal number from the CPU 110 of the PBX 101 via the computer line 111 and processes the information.

  Further, for example, as shown in FIG. 8, the private branch exchange system 120 described in the cited document 2 includes three nodes including a network control node (NCN) 121A, local network nodes (LN) 121B and 121C, and each node. Host computers 122A, 122B and 122C connected to 121A to 121C, a server 123 connected to all the nodes 121A to 121C via the Internet line 130, and a cabin connected to each of the nodes 121A to 121C Telephones 124A and 124B, and a relay board 125 connected to the network control node 121A.

  Each of the network control node 121A and the local network nodes 121B and 121C includes communication path switches (TDSW) 131A, 131B, and 131C and communication control units 132A, 132B, and 132C. Information necessary for controlling various service functions in the network control node 121A and the local network nodes 121B and 121C is held in a station data storage memory (not shown), and local station data (LDM) 133A is information unique to each node. 133B and 133C, and network station data (NDM) 134A, 134B and 134C common to each node.

  The server 123 includes a database 141 for deriving host computers 122A to 122C of nodes corresponding to guest rooms, and an event transfer circuit 142 for transferring various information to the host computers 122A to 122C of the nodes 121A to 121C.

  In the private branch exchange system 120, when the network control node 121A causes the host computer of another guest room to process the guest room information of each different guest room, the network control node 121A uses the detected guest room information to the database 141 connected via the Internet line 130. Search for processing nodes. The network control node 121A transfers the room information from the event transfer circuit 142 to the host computers 122A to 122C of the searched processing node.

  However, in the private branch exchange system described in the cited document 1, only a one-to-one connection between the private branch exchange and the host computer is considered. In the private branch exchange system described in the cited document 2, the private branch exchange and the host computer are considered. Is considered only in a multiple-to-multiple connection. Therefore, there has been a problem that one private branch exchange cannot be connected to a plurality of host computers.

  This is because, in a conventional private branch exchange system, normally, when using a private branch exchange, security is implemented so that calls can be made only within the own facility. For such security, different systems are applied to each facility. For example, when one private branch exchange is shared by multiple facilities, the same security is implemented using conventional technology. Difficult to do.

  Conventionally, since a host computer to which a unique communication format is applied for each facility is used, a single private branch exchange cannot handle a plurality of host computers.

  Further, in the conventional private branch exchange system, when one private branch exchange is connected to a plurality of host computers, the room information received from the host computer cannot be displayed and controlled for each facility. For example, when room information is searched when one private branch exchange is used at a plurality of hotels, room information of other hotels may be displayed as a search result. This is because room information that can be managed by one private branch exchange is fixed to only one hotel.

  In addition, in the conventional private branch exchange system, there is a one-to-one correspondence between the private branch exchange and the host computer, so it is necessary to install a private branch exchange in each facility. However, if a private branch exchange is installed in each facility, Will occupy a certain space inside. As a result, there is a problem in that the space in the facility cannot be used effectively and the cost increases.

  Accordingly, the present invention has been made in view of the problems in the above-described conventional technology, and can provide existing services and security even when one private branch exchange is connected to a plurality of host computers. The aim is to provide a possible private branch exchange system.

  Another object of the present invention is to provide a private branch exchange system capable of reducing the space occupied by a private branch exchange installed in a hotel and reducing the cost.

In order to achieve the above object, the present invention provides a private branch exchange system, a host computer for processing room information relating to a guest of a guest room, and a telephone provided for each guest room for making a call with an external or other guest room. A room indicator that displays the occupancy status of the guest room is installed in each of one or a plurality of facilities, connected to the host computer, and transmission / reception of the guest room information to / from the host computer and the guest room information The one or more facilities comprising: a server for managing the telephone; a private branch exchange connected to the telephone and the server for performing telephone exchange processing; and an answering machine connected to the server and the private branch exchange for storing messages Installed in another facility different from the server, the server includes facility identification information for identifying each of the one or more facilities and the one or more facilities. And assigning an extension number number band to the telephone set, and managing the guest room information, and a database storing the facility identification information and the number band in association with each other, wherein the control unit includes the facility identification Information and the room information transmitted from the host computer are associated with each other and registered in the database, the private branch exchange is set so that only a call between the same number bands is possible, and the room indicator is The room occupancy information indicating the occupancy status of the guest room is transmitted to the server, and the server is assigned the received room occupancy information to the facility where the room indicator is installed by the control unit. In addition to registering in the database in association with the facility identification information, transmitting the cabin occupancy information to the private branch exchange, And the server sets the incoming call to the telephone set in the absent guest room to be forwarded to the answering machine when the received guest room presence information indicates the absence of the guest room, When the message is stored in the answering machine, the information indicating that the message is stored is added to the room information associated with the facility identification information and registered .

  According to the present invention, facility identification information is assigned to each facility, and one private branch exchange and a plurality of host computers are connected to control services and security in each facility based on the facility identification information. Even in this case, it is possible to provide services and security similar to those in the past.

  In addition, according to the present invention, since the host computer is installed in each facility and the private branch exchange is installed in another facility different from these facilities, the space occupied by the private branch exchange that has conventionally been installed in each facility is reduced. Can be reduced.

Furthermore, according to the present invention, when the room occupancy information indicates the absence of the guest room, the incoming call to the telephone set in the absent guest room is set to be transferred to the answering machine, and a message is stored in the answering machine. Information indicating that the message has been stored in addition to the room information associated with the facility identification information, even if one private branch exchange and a plurality of host computers are connected, In the same way as above, it is possible to properly display the occupancy status of the guest room, to store a message when there is an incoming call when there is no call, and to search for room information using the attendant console In addition, the presence or absence of the stored message can be confirmed.

  In the private branch exchange system, when a wake-up call is set by an operation on the telephone, the private branch exchange sets a wake-up call based on the operation on the telephone and setting information indicating that the wake-up call is set The server associates the received setting information with the facility identification information assigned to the facility where the telephone set with the wake-up call is installed by the control unit. And the setting information can be transmitted to the host computer of the facility to which the corresponding facility identification information is assigned. Thereby, when the guest room information is searched, it can be confirmed as a search result whether or not the wake-up call is set.

  In the private branch exchange system, when the private branch exchange executes the wake-up call, the private branch exchange transmits execution information indicating an execution result of the wake-up call to the server, and the server receives the execution received by the control unit. The information is registered in the database in association with the facility identification information assigned to the facility where the telephone on which the wake-up call is executed is installed, and the execution information is registered for the facility to which the corresponding facility identification information is assigned. It can be sent to the host computer. Thereby, when the guest room information is searched, the execution result for the wake-up call can be confirmed as the search result.

  In the private branch exchange system, a plurality of private branch exchanges are installed in the other facility, and the control unit assigns exchange identification information for identifying the plurality of private branch exchanges, and among the plurality of private branch exchanges, A private branch exchange corresponding to each of the one or more facilities can be determined, and the facility identification information and the exchange identification information assigned to the associated private branch exchange can be associated and registered in the database. . Thereby, even when a plurality of private branch exchanges are used, it is not necessary to install the private branch exchange in a facility such as a hotel, so that the space occupied by the private branch exchange can be reduced.

  As described above, according to the present invention, existing services and security can be provided even when one private branch exchange is connected to a plurality of host computers.

  Further, according to the present invention, it is possible to reduce the occupied space by the private branch exchange installed in the hotel and reduce the cost.

  Next, an embodiment for carrying out the present invention will be described in detail with reference to the drawings. Here, a case where the private branch exchange system according to the present invention is applied to a hotel will be described as an example.

  FIG. 1 shows a first embodiment of a private branch exchange system according to the present invention. In this private branch exchange system 1, a plurality of hotels 2A, 2B and 2C and a data center 3 which is a facility different from these hotels are shown. Are connected via the Internet lines 4A and 4B.

  In the hotels 2A, 2B and 2C, telephones 11A, 11A,... Are installed in each guest room, and are used to make external calls (outside line transmission) or calls to different telephones in the same hotel (internal line transmission). 11B, 11B,... And 11C, 11C,... And the relay consoles 12A, 12B, and 12C, etc., are installed at the front desk, etc. Host computers 13A, 13B, and 13C that perform processing are installed.

  In the data center 3, a hotel server 21 and a private branch exchange 22 are installed. The telephones 11A, 11B, and 11C are connected to the private branch exchange 22 through the Internet line 4A, and the relay stations 12A, 12B, and 12C, the host computers 13A, 13B, and 13C, and the hotel server 21 are connected through the Internet line 4B. Is done.

  As shown in FIG. 2, the hotel server 21 is a host computer that controls communication between the private branch exchange communication control unit 31 that controls communication with the private branch exchange 22 and host computers 13A, 13B, and 13C installed in each hotel. The communication control unit 32, the private branch exchange communication control unit 31 and the host computer communication control unit 32 are configured by a hotel control unit 33 that controls management of various information exchanged by communication and a management database 34.

  In the management database 34, a hotel ID (IDentification), which is assigned for each hotel and is used to identify each hotel, and the extension number band used for each hotel, the room information in the hotel, etc. Registered in association. The room information associated with the hotel ID is, for example, information relating to the guest room user, such as the guest room number, the guest room user's name, and nationality.

  The private branch exchange 22 is a device for performing a telephone exchange process for connecting a source telephone line and a destination telephone line to each other. The private branch exchange 22 is set based on the notification from the hotel server 21 so that only calls using the same number band are possible, and based on the extension numbers of the caller and callee, the two extension numbers are set to the same number band. Judge whether it belongs or not. When the two extension numbers are in the same number band, the telephone lines are connected to each other.

  Moreover, the private branch exchange 22 can restrict the function of the telephone set installed in each hotel. For example, it is possible to restrict a call function from a telephone set in a guest room that is not used so that an outside line cannot be transmitted.

  Next, the operation of the private branch exchange system 1 having the above configuration will be described. Normally, a hotel ID and a number band are assigned in advance by the hotel control unit 33 of the hotel server 21 to each hotel where the private branch exchange system 1 is introduced, and the hotel ID and the number band are associated with each other in the management database. 34 and the private branch exchange 22 is set so that only calls using the same number band can be made.

  In such a state, only a call between the same number bands is possible, and a call between different number bands is impossible. Specifically, for example, a telephone call can be made between the telephone 11A of the hotel 2A, between the telephone 11B of the hotel 2B, and between the telephone 11C of the hotel 2C, and between the telephone 11A and the telephone 11B, between the telephone 11B and the telephone 11C, and the telephone. Communication between 11A and the telephone 11C becomes impossible.

  For example, a telephone 11A installed in a predetermined guest room of the hotel 2A (for example, “Guest Room # 1”) and a telephone 11A installed in another room of the hotel 2A (for example, “Guest Room # 2”) , The private branch exchange 22 belongs to each extension number based on the extension number of the telephone 11A of the caller guest room # 1 and the extension number of the telephone 11A of the callee guest room # 2. It is determined that the number bands are the same, and the telephone lines of the telephones 11A of the guest rooms # 1 and # 2 are connected.

  Here, a case where another hotel is newly added to the private branch exchange system 1 will be described. Here, for ease of explanation, a case where a hotel 2A is newly added to the private branch exchange system 1 will be described as an example.

  When a connection request is transmitted from the host computer 13A installed in the hotel 2A to the hotel server 21, the host computer communication control unit 32 of the hotel server 21 and the host computer 13A are connected via the Internet line 4B. The connection request from the host computer 13A is received by the host computer communication control unit 32 of the hotel server 21, and the host computer communication control unit 32 supplies the received connection request to the hotel control unit 33.

  Upon receiving a connection request from the host computer 13A, the hotel control unit 33 assigns a hotel ID to the host computer 13A, determines a number band used in the hotel 2A, and assigns a hotel ID assigned to the hotel 2A. And the number band are registered in the management database 34 in association with each other.

  Next, the private branch exchange communication control unit 31 and the private branch exchange 22 are connected, and the hotel control unit 33 enables a call between the number bands assigned to the hotel 2A, and at the same hotel as the number band. The private branch exchange 22 is notified so that the telephone call between the assigned number band and the number cannot be made.

  The private branch exchange 22 sets a connection line based on the notification received from the hotel server 21. As a result, a telephone call between the telephone 11A of the hotel 2A and the telephone 11B of the hotel 2B, a telephone call between the telephone 11B of the telephone 11B and the hotel 2C, and a telephone call between the telephone 11A and the telephone 11C are disabled. Calls between each other are possible.

  Next, an operation when a guest room user checks in and checks out will be described. Here, a case where a guest room user of the hotel 2A checks in will be described as an example.

  When a guest room user of the hotel 2A checks in and guest room information is input to the front host computer 13A, the host computer 13A sends the hotel ID and a check-in text indicating the guest room information via the Internet line 4B to the hotel server. To 21.

  The hotel ID and check-in text transmitted from the host computer 13A are received by the host computer communication control unit 32 of the hotel server 21. The host computer communication control unit 32 receives the received hotel ID and check-in text in the hotel control unit 33. To supply.

  The hotel control unit 33 analyzes the contents of the check-in text received via the host computer communication control unit 32. Thereby, the hotel control unit 33 obtains the guest room information such as the guest room number, the guest user's name and nationality. Then, the received hotel ID is compared with the hotel ID registered in the management database 34, and the room information obtained by the analysis is registered in the management database 34 in association with the corresponding hotel ID.

  Further, the hotel control unit 33 sends the check-in information indicating that the check-in text has been received from the host computer 13A, that is, the guest room user of the hotel 2A, through the private branch exchange communication control unit 31. Transmit to the switch 22. Based on the check-in information received from the hotel server 21, the private branch exchange 22 releases the restriction on the function of the telephone 11 </ b> A installed in the target guest room, for example, and sets the function such as outgoing line transmission to be usable. .

  When the guest room user of the hotel 2A checks out, the host computer 13A transmits the hotel ID and checkout information indicating the checkout to the hotel server 21. Upon receiving the hotel ID and checkout information via the host computer communication control unit 32, the hotel control unit 33 deletes the room information associated with the corresponding hotel ID from the management database 34. The hotel control unit 33 also transmits checkout information for the guest room user of the hotel 2A to the private branch exchange 22 via the private branch exchange communication control unit 31.

  Based on the check-out information received from the hotel server 21, the private branch exchange 22 limits the function of the telephone 11 </ b> A installed in the target guest room and sets the function such as outside line transmission to be unusable.

  Here, the guest room information and the number band are registered in the management database 34 in association with the hotel ID. The room information registered in the management database 34 is used, for example, when searching for room information from the relay board. For example, when the room information search is performed from the relay board 12A installed in the hotel 2A, the hotel control unit 33, based on the hotel ID of the relay board 12A that has searched, the room information associated with the corresponding hotel ID. Is transmitted from the management database 34 and transmitted to the relay console 12A.

  Thus, in this Embodiment, since room information is managed by hotel ID, appropriate room information can be obtained without reading out room information of different hotels as a search result when searching for room information.

  Next, the operation when executing a wake-up call will be described. Here, a case where a guest room user of the hotel 2B executes a wake-up call will be described as an example.

  When a guest room user of the hotel 2B operates the telephone 11B to set a wake-up call, information indicating the setting of the wake-up call corresponding to the operation is transmitted to the private branch exchange 22 via the Internet line 4A. The private branch exchange 22 sets a wake-up call for the telephone 11B based on the received information. The private branch exchange 22 transmits wake-up call setting information indicating that a wake-up call has been set for the telephone 11B to the hotel server 21.

  The hotel control unit 33 receives the wake-up call setting information via the private branch exchange communication control unit 31, and adds the wake-up call setting information to the room information associated with the corresponding hotel ID in the management database 34. Thereby, when the guest room information is searched using the relay console 12B of the hotel 2B, it can be confirmed whether or not each guest room user has set a wake-up call.

  When executing the wake-up call, the private branch exchange 22 executes the wake-up call to the telephone set 11B on which the wake-up call is set. Then, the private branch exchange 22 transmits to the hotel server 21 wake-up call execution information indicating execution results such as whether or not there is a response to the wake-up call.

  The hotel control unit 33 receives the wake-up call execution information via the private branch exchange communication control unit 31, and adds the wake-up call execution information to the room information associated with the corresponding hotel ID in the management database 34. The hotel control unit 33 transmits wake-up call execution information to the host computer 13B having the corresponding hotel ID via the host computer communication control unit 32. Thereby, at the front of the hotel 2B, the execution result of the set wake-up call can be confirmed. For example, when the response is not made, it is possible to take measures such as manually executing the wake-up call again.

  As described above, according to the first embodiment, a hotel ID is assigned to each hotel, and a private branch exchange and a plurality of host computers are used to control calls and various services at each hotel based on the hotel ID. Existing services and security can be provided even when connected to.

  Moreover, since the private branch exchange shared by each hotel is installed outside the hotel, the occupied space by the private branch exchange that has been conventionally installed in each hotel can be reduced, and the cost can be reduced.

  Next, a second embodiment of the private branch exchange system according to the present invention will be described. FIG. 3 shows a second embodiment of the private branch exchange system according to the present invention. In the example shown in FIG. 3, only the hotel 2A is shown as a hotel connected to the data center 3 through the Internet lines 4A and 4B in order to prevent the explanation from being complicated, and the other hotels 2B and 2C are shown in the figure. Although not described, the hotels 2B and 2C are assumed to be connected to the data center 3 as in the first embodiment.

  The private branch exchange system 40 includes a room indicator 14 in the hotel 2A and a guest room answering phone 42 in the data center 3 in addition to the configuration of the private branch exchange system 1 according to the first embodiment. A message can be stored by forwarding an incoming call received when the user is absent to the guest room answering machine 42.

  The room indicator 14 is installed at the front or the like, and displays information indicating the occupancy state (occupied or absent) of each guest room. The room indicator 14 is connected to the hotel server 41 in the data center 3 via the Internet line 4B, and transmits the room occupancy information indicating the occupancy state of the guest room to the hotel server 41.

  For example, the telephone 11 </ b> A is provided with a display unit that indicates whether there is a message due to an incoming call when there is no call. For example, when there is an incoming call when the guest of the guest room is absent and a message is stored in the guest room answering machine 42, the display unit displays that the message has been stored.

  In the data center 3, a hotel server 41, a guest room answering machine 42, and a private branch exchange 22 are installed. As shown in FIG. 4, the hotel server 41 includes a private branch exchange communication control unit 31, a hotel control unit 33, a management database 34, and a room indicator communication control unit 43 that controls communication with the room indicator 14. Although not shown, the hotel server 41 also includes a host computer communication control unit 32 as in the first embodiment.

  The guest room answering machine 42 is a telephone having a function of storing a message from a caller, and is connected to the hotel server 41 and the private branch exchange 22. For example, when there is an incoming call to a telephone in a guest room that is absent, the incoming call to the telephone in the guest room is transferred to the answering machine 42 under the control of the private branch exchange 22 and is automatically answered to the caller. And memorize the message. When the message is stored, the guest room answering machine 42 transmits message information indicating that the message has been stored to the hotel server 41 and the private branch exchange 22.

  Next, the operation of the private branch exchange system 40 having the above configuration will be described. First, the occupancy state of the guest room is set by the guest room user. Various methods are conceivable as a method for setting the occupancy state of the guest room. For example, in each guest room, a device (not shown) connected to the room indicator 14 for setting the occupancy state is installed. When the guest room user operates this device, the occupancy state of the guest room is set. The room indicator 14 displays the occupancy state of the guest room according to the operation on the device.

  When the occupancy state of the guest room is set by the guest room user, the room indicator 14 transmits the hotel ID and the guest room occupancy information to the hotel server 41 via the Internet line 4B. The hotel ID and the guest room occupancy information transmitted from the room indicator 14 are received by the room indicator communication control unit 43 of the hotel server 41, and the room indicator communication control unit 43 controls the received hotel ID and guest room occupancy information as a hotel. To the unit 33.

  Based on the received hotel ID, the hotel control unit 33 adds the occupancy state based on the occupancy information to the occupancy information associated with the corresponding hotel ID in the management database 34. Thereby, when searching for room information using the relay stand 12A of the hotel 2A, it is possible to check the occupancy state of each guest room user.

  In addition, the hotel control unit 33 transmits cabin occupancy information to the private branch exchange 22 via the private branch exchange communication control unit 31. The private branch exchange 22 sets the incoming call to the telephone 11 </ b> A to the guest room answering machine 42 based on the guest room occupancy information received from the hotel server 41.

  When there is an incoming call from the outside or the like to the telephone 11A, the private branch exchange 22 transfers the incoming call to the telephone 11A to the guest room answering machine 42. The room answering machine 42 automatically responds to incoming calls and stores the message. When the message is stored, the guest room answering machine 42 transmits the message information to the hotel server 41 and the private branch exchange 22.

  When the hotel control unit 33 of the hotel server 41 receives the message information from the guest room answering machine 42, the hotel information stored in the guest room answering machine 42 is stored in the guest room information associated with the corresponding hotel ID in the management database 34. Add information to indicate. Thereby, when the guest room information is searched using the relay board 12A of the hotel 2A, the presence or absence of the stored message can be confirmed.

  Further, when the private branch exchange 22 receives the message information from the guest room answering machine 42, it notifies the forwarding telephone 11A that the message has been stored in the guest room answering machine 42. Thereby, a notification indicating that the message has been stored in the guest room answering machine 42 is displayed on the display unit provided in the telephone 11A.

  When a message is reproduced using the telephone 11A, the guest room answering machine 42 determines the hotel from the hotel ID and extension number of the telephone 11A, and the message stored in the guest room answering telephone 42 is reproduced. Perform playback.

  Note that the method of setting the occupancy state of the guest room is not limited to the above example, and for example, the occupancy state can also be set by operating the telephone 11A by the user of the guest room. In this case, the private branch exchange 22 transmits the hotel ID and the room occupancy information to the hotel server 41 based on the setting from the telephone 11A.

  The hotel ID and guest room occupancy information transmitted from the private branch exchange 22 are received by the private branch exchange communication control unit 31 of the hotel server 41, and the private branch exchange communication control unit 31 performs hotel control on the received hotel ID and guest room occupancy information. To the unit 33. Based on the received hotel ID, the hotel control unit 33 adds the occupancy state based on the occupancy information to the occupancy information associated with the corresponding hotel ID in the management database 34.

  In addition, the hotel control unit 33 transmits the room presence information to the room indicator 14 via the room indicator communication control unit 43. The room indicator 14 displays the occupancy status of the guest room based on the occupancy information received from the hotel server 41.

  As described above, according to the second embodiment, as in the first embodiment, a hotel ID is assigned to each hotel, and the occupancy status display control or absence of each guest room at each hotel is based on the hotel ID. Since an answering machine is set at the time, even when one private branch exchange is connected to a plurality of host computers, an existing service can be provided.

  Next, a third embodiment of the private branch exchange system according to the present invention will be described. FIG. 5 shows a third embodiment of the private branch exchange system according to the present invention. In the example shown in FIG. 5, only the hotels 2A and 2B are shown as the hotels connected to the data center 3 through the Internet lines 4A and 4B in order to prevent the explanation from being complicated, and the other hotels 2C are shown. Although not described here, it is assumed that the hotel 2C is connected to the data center 3 as in the first embodiment.

  In this private branch exchange system 50, a plurality of private branch exchanges 22A and 22B are provided in the data center 3 with respect to the configuration of the private branch exchange system 1 according to the first embodiment. The private branch exchanges 22A and 22B are private branch exchanges having the same functions as the private branch exchange 22 shown in FIGS. The private branch exchanges 22A and 22B are connected to telephones 11A and 11B installed in guest rooms of the hotels 2A and 2B via Internet lines 51A and 51B, respectively. Also, the private branch exchanges 22A and 22B are pre-assigned with an exchange ID for identifying each private branch exchange.

  For example, the telephone set installed in each hotel is connected to the same private branch exchange for each hotel, and the correspondence between the telephone and the private branch exchange is fixed. In the example shown in FIG. 5, for example, the telephones 11A, 11A,... Installed in the hotel 2A are connected to the private branch exchange 22A via the Internet line 51A, and the telephones 11B, 11B,. Is connected to the private branch exchange 22B via the Internet line 51B.

  As shown in FIG. 6, the hotel server 21 includes a private branch exchange communication control unit 31, a host computer communication control unit 32, a hotel control unit 33, and a management database 34. For example, when a hotel is newly added to the private branch exchange system 50, the hotel control unit 33 determines a private branch exchange to be connected to a telephone installed in the hotel. In this case, in order to prevent the load from being concentrated on some private branch exchanges, for example, each time a new hotel is added to the private branch exchange system 50, a decision is made to associate a plurality of private branch exchanges in order. It is preferable.

  In the management database 34, a hotel ID for identifying a hotel, an exchange ID for identifying a private branch exchange associated with the hotel, an extension number assigned to the hotel, and room information related to a guest room user are mutually stored. Registered in association.

  Next, the operation of the private branch exchange system 50 having the above configuration will be described. Normally, a hotel ID and a number band are assigned in advance by the hotel control unit 33 of the hotel server 21 to each hotel where the private branch exchange system 50 is introduced, and an exchange ID is assigned in advance to each private branch exchange. It is done.

  In the management database 34, a hotel ID, an exchange ID, and a number band are associated and registered. The private branch exchanges 22A and 22B are set such that only calls using the same number band are possible. In such a state, only a call between the same number bands is possible, and a call between different number bands is impossible.

  Next, a case where another hotel is newly added to the private branch exchange system 50 will be described. Here, for ease of explanation, a case where a hotel 2A is newly added to the private branch exchange system 50 will be described as an example.

  When a connection request is transmitted from the host computer 13A installed in the hotel 2A to the hotel server 21, the host computer communication control unit 32 of the hotel server 21 and the host computer 13A are connected via the Internet line 4B. The connection request from the host computer 13A is received by the host computer communication control unit 32 of the hotel server 21, and the host computer communication control unit 32 supplies the received connection request to the hotel control unit 33.

  Upon receiving a connection request from the host computer 13A, the hotel control unit 33 assigns a hotel ID to the host computer 13A and determines a number band used in the hotel 2A. The hotel control unit 33 determines a private branch exchange to be connected to the telephone 11A installed in the hotel 2A. In this example, the telephone 11A and the private branch exchange 22A are connected. Then, the hotel control unit 33 registers the hotel ID and number band assigned to the hotel 2A and the exchange ID of the private branch exchange 22A in the management database 34 in association with each other.

  Next, the private branch exchange communication control unit 31 and the private branch exchange 22A are connected, and the hotel control unit 33 enables a telephone call between the number bands assigned to the hotel 2A, and at the same time as this hotel. The private branch exchange 22A corresponding to the exchange ID registered in the management database 34 in association with the hotel ID of the hotel 2A is notified so as to make a call between the number band assigned to the hotel 2A impossible.

  The private branch exchange 22A sets a connection line based on the notification received from the hotel server 21. As a result, only the telephone call between the telephones 11A of the hotel 2A becomes possible, and the telephone call between the telephone 11A and the telephone of another hotel connected to the private branch exchange 22A becomes impossible.

  Thus, by identifying a plurality of private branch exchanges using the exchange ID, for example, when transmitting data from the host computer in the hotel to the private branch exchange via the hotel server, the destination private branch exchange is mistaken. And data can be transmitted appropriately.

  As described above, according to the third embodiment, a switch ID is assigned to a plurality of private branch exchanges, and a private branch exchange corresponding to each hotel telephone is determined based on the switch ID. Existing services and security can be provided while connecting to the host computer.

  Moreover, since a plurality of private branch exchanges are installed outside the hotel, the space occupied by the private branch exchanges conventionally installed in each hotel can be reduced, as in the first and second embodiments, and the cost can be reduced. Can be reduced.

  The first, second, and third embodiments of the present invention have been described above. However, the present invention is not limited to the above-described first, second, and third embodiments of the present invention, and the present invention is not limited thereto. Various modifications and applications are possible without departing from the scope of the invention. For example, in the above-mentioned example, the case where the private branch exchange system is applied to a hotel has been described. However, the present invention is not limited to this, and this is also applicable to facilities such as inns and training centers that provide guest rooms and private rooms to users. A private branch exchange system can be applied.
