Description

  The present invention relates to a private branch exchange, (PBX (Private Branch Exchange)), a private branch exchange program, a private branch exchange system, and an IP (Internet Protocol) telephone terminal, and for example, relates to a private branch exchange system having a function of simultaneously calling a plurality of extension telephones.

  In general, a private branch exchange used in a company uses a group incoming call function that can simultaneously call a plurality of extension telephones as a destination when an incoming call is made to an external number of the company. The private branch exchange is also provided with a general call function capable of making a conference call with a plurality of extension telephones by applying the group reception. These functions are utilized in a work environment where a plurality of people cooperate to perform work.

  It should be noted that recent private branch exchanges can accommodate IP extension telephones utilizing IP technology. The accommodated IP extension telephones can be used by connecting to a private company IP network and controlling connection with a private branch exchange connected to the IP network. The private branch exchange is also capable of accommodating an office cordless extension telephone (PHS (Personal Handy-phone System) extension telephone) which is a mobile extension (Patent Document 1).

  Similarly, these IP extension telephones and PHS extension telephones can use the above-described function related to group reception. Also, these various extension telephones can be used in combination.

  The IP extension telephone can be connected from any location if it can be connected on the corporate IP network such as another floor, another base, outside the company, business trip, etc., and the connection control with the private branch exchange can be realized. It is possible to do. Furthermore, IP extension telephones having a wireless interface are more utilized because of their increased mobility.

  The PHS extension telephone can be connected from another floor or another base as long as a connectable PHS base station is located nearby. The PHS base station is connected to the private branch exchange and relays connection control of the PHS extension telephone registered in the private branch exchange.

  When a group incoming call is made to an extension telephone, the following processing is performed.

  The group setting in the private branch exchange may be performed by selecting a plurality of extension telephones corresponding to the place where the call is to be received.

  In the vicinity of the extension telephone associated with the group call, a plurality of extension telephones registered in the group ring and a response is made by a person in the vicinity. As for the situation of the respondent, the response and the call situation can be identified by visual observation or the like in the surroundings, so that it can be recognized that another person responded to the group incoming response. However, conventional non-IP fixed telephones using metal wiring (hereinafter also referred to as "legacy telephones") are directly connected to the private branch exchange and are installed at fixed locations. When a group call is received, the telephone in a fixed location always rings. In other words, the location of the destination is clear.

  On the other hand, since IP extension telephones and PHS extension telephones are not always connected at fixed locations as described above, users not only respond to incoming calls at fixed locations such as their seats, but also There is a case where an incoming call is answered in an unusual place.

  For example, when a group incoming call is received while a user of an IP extension telephone or a PHS extension telephone is present at his or her desk, a plurality of surrounding telephones ring and it is possible to visually confirm who answered and so on. It is easy to disseminate the information to others and handle the hold transfer.

  However, if the user of the IP extension telephone or the PHS extension telephone answers at a place other than his / her own seat, it is well known that the other party present around his / her seat receives an incoming call and that the own extension telephone has answered ( Grasp). In other words, there has been a case where a misunderstanding such as disconnection from the caller side without any response to the incoming call has occurred.

  Also, if a person who answers in a place other than his / her own room attempts to perform a hold transfer to another extension of the person near his / her seat, the situation around his / her seat is unknown and the caller cannot be transferred. There was also a case where it was time-consuming to have them start over again.

  FIG. 16 is an explanatory diagram showing a specific example of a conventional group incoming call.

  When dialing "On-abcd-efgh" (an arbitrary number is applied to the alphabet) from an outside line (connection destination designation), the private branch exchange sets the telephone number to each extension telephone set to group A. To the group. At this time, the IP extension telephone 30-1, the IP extension telephone 30-2, and the PHS extension telephone 40 are moving from their own seats (not at their own seats on the floor 1) and receive incoming calls at another place.

  At this time, when the PHS extension telephone 40 that has moved to the floor M first answers, an incoming call from an outside line is put into a response call state by the PHS extension telephone 40. However, although ringing stops for other extensions that have received an incoming call at their own seat, nobody can visually confirm that no response has been made around the user's seat, and this makes it difficult to understand the response handling status of the incoming call.

  There is also a general paging function utilizing a group incoming call function. In this function, a plurality of extension telephones are simultaneously called by a caller, and a conference call is performed with the plurality of extension telephones. The paging function may be used as a conference call with people in a specific area such as around his / her own seat. In such a case, if an IP extension telephone or PHS extension telephone is included in the call destination, As in the case of the group incoming call, there is no need to participate in the conference call, although it is not present at the user's seat, but there was a situation where the call was received as a general call destination.

  FIG. 17 is an explanatory diagram showing a specific example of the conventional simultaneous call function.

  In order for the extension X to make a simultaneous call to the extension registered in the group A, the user dials "8-701" which is the general call number of the group A, and the IP extension telephone 30-1 moving from the floor 1 and the IP extension telephone 30-1 A call is also made to the extension telephone 30-2 and the PHS extension telephone 40. When each of them answers, a conference call is established with all the extension telephones registered in the extension X and the group A. The IP extension telephone 30-1, IP extension telephone 30-2, and PHS extension telephone 40 are not in the vicinity of their own seat, so there is no need to listen to a conference call, but unnecessary telephone responses occur.

  As described above, the setting of the group destination of the private branch exchange (including the paging function) is performed by setting the destination extension telephone fixedly, so that the connection destination such as the IP extension telephone and the PHS extension telephone described above is used. It is necessary to use an extension phone that is not fixed, but it is necessary when you are at your seat, but it is not necessary when you are not at your seat, but you may receive a call and it is not convenient for users There were challenges.

(A) less than the first embodiment, the private branch exchange according to the present invention, private branch exchange program, and the first embodiment of the PBX system will be described with reference to the drawings.

(A-1) Configuration of First Embodiment FIG. 1 is a block diagram showing the configuration of the entire private branch exchange system including the private branch exchange according to the first embodiment.

  In FIG. 1, the private branch exchange system 1 includes a private branch exchange 10, a legacy extension telephone 20 (20-1, 20-2), an IP extension telephone 30 (30-1, 30-2), a PHS extension telephone 40, and a wireless LAN access. Point (hereinafter also referred to as “wireless LAN-AP”) 50 (50-1, 50-2, 50-3) and PHS base station 60 (60-1, 60-2).

  In the following, for the sake of simplicity, if there is no need to distinguish between the IP extension telephones 30-1 and 30-2, the description will be given as the IP extension telephone 30. The same applies to the legacy extension telephones 20 (20-1, 20-2), the wireless LAN access point 50 (50-1, 50-2, 50-3), and the PHS base station 60 (60-1, 60-2). I do.

  The private branch exchange 10 accommodates legacy extension telephones 20-1 and 20-2, IP extension telephones 30-1 and 30-2, and a PHS extension telephone 40. The IP extension telephones 30-1 and 30-2 are accommodated in the private branch exchange 10 via a corporate IP network N2. Here, the accommodation means connection and identification. In other words, the private branch exchange 10 is connected to each of the legacy extension telephones 20-1 and 20-2, the IP extension telephones 30-1 and 30-2, and the PHS extension telephone 40 to identify each of them. The private branch exchange 10 also houses an external public subscriber telephone network (public network) (external line network) not shown in FIG. When accommodating, the private branch exchange 10 has a legacy (analog) accommodating I / F (interface) for accommodating the legacy extension telephone set 20, and has a corporate IP network N2 (an IP extension telephone 30 via the corporate IP network N2). ), And a PHS accommodating I / F for accommodating the PHS base station 60 (the PHS extension telephone 40 via the PHS base station 60). It has an external line accommodating I / F for accommodating a telephone network (external line network). The connection in the accommodation of the private branch exchange 10 means communication based on a predetermined communication protocol, and the identification means identification of a terminal type and a line type based on the communication protocol.

  The private branch exchange 10 has a function of exchanging an extension call between each of the legacy extension telephone set 20, the IP extension telephone set 30, and the PHS extension telephone set 40, and a function of exchanging the legacy extension telephone set 20, the IP extension telephone set 30, and the PHS extension telephone set 40. A function of exchanging external calls between the telephone and the external public telephone network. For example, the private branch exchange 10 corresponds to an IP-PBX, a soft switch, or the like. The private branch exchange 10 may be a relay device such as a switch or a router, or may be a communication device such as a personal computer, as long as it has a function related to telephone connection.

  FIG. 2 is a block diagram showing a main internal configuration of the private branch exchange 10.

  The private branch exchange 10 includes an interface unit 11, a call processing unit 12, a destination determination unit 13 and a storage unit 14 as constituent elements.

  The private branch exchange according to the first embodiment can be configured by hardware except for the interface unit, and can also be realized by software (private exchange program) executed by the CPU and the CPU. Although it is possible, the function can be represented in FIG. 2 regardless of the method of implementation.

  The interface unit 11 is an interface for performing communication processing by connecting to a public network or an extension telephone. The interface unit 11 includes a legacy (analog) accommodating I / F, an IP network accommodating I / F, a PHS accommodating I / F, and an external line accommodating I / F, and is configured by a circuit constituting each I / F. Each I / F may be realized by configuring a circuit for each I / F on one substrate (package), or may be realized on a substrate (package) for each I / F. May be realized. Although the interface unit 11 includes the legacy (analog) accommodating I / F, the IP network accommodating I / F, the PHS accommodating I / F, and the external line accommodating I / F, the interface unit 11 according to the premises according to the first embodiment. It has a legacy extension telephone set 20, an IP extension telephone set 30, and a PHS extension telephone set 40 as in the exchange system 1, and has a configuration adapted to a mode of connecting to a public subscriber telephone network (external line network). For example, in the case of a private branch exchange system 1 having an IP extension telephone 30 and a PHS extension telephone 40 and connected to a public subscriber telephone network (external line network), the interface unit 11 includes an IP network accommodating I / F and a PHS accommodating I / F. / F and an external line accommodating I / F, and may be configured by a circuit configuring each I / F. In other words, the interface unit 11 sets one or more of the legacy (analog) accommodating I / F, the IP network accommodating I / F, the PHS accommodating I / F, and the external line accommodating I / F in accordance with the mode of the private branch exchange system 1. Including.

  The call processing unit 12 controls call processing for a connection request from a public network or an extension telephone. The call processing unit 12 controls call processing via one or more of a legacy (analog) accommodation I / F, an IP network accommodation I / F, a PHS accommodation I / F, and an outside line accommodation I / F. For example, when the private branch exchange 10 (the call processing unit 12) receives a connection request for the IP extension telephone 30-2 from a public network (a terminal on the public network side), the call processing unit 12 uses the external line accommodating I / F and the IP network. It controls call processing for establishing a call between the public network (the terminal on the public network side) and the IP extension telephone 30-2 via the accommodation I / F. For example, when the private branch exchange 10 (the call processing unit 12) receives a connection request for the IP extension telephone 30-2 from the IP extension telephone 30-1, the call processing unit 12 transmits the IP extension via the IP network accommodating I / F. It controls call processing for establishing a telephone call between the telephone 30-1 and the IP extension telephone 30-2. For example, when the private branch exchange 10 (the call processing unit 12) receives a connection request for a simultaneous call to the group A from a public network (a terminal on the public network side), the call processing unit 12 uses the external line accommodating I / F and the legacy (analog). ) Controls call processing for establishing a call between the accommodation I / F, the IP network accommodation I / F, and the PHS accommodation I / F.

  The destination determination unit 13 determines a destination telephone for a call for which a connection request has been made (destination determination processing). If the result of the dial analysis indicates that there is a specific special number (group incoming call or general call), the call destination determining unit 13 determines one or more telephones linked to the special number as the call destination.

  The storage unit 14 stores data relating to the extension telephones accommodated by the private branch exchange 10 and the location of the extension telephones, special numbers, and the like. In this embodiment, as shown in FIG. 1, the special numbers of the group A of the group A include the legacy extension telephones 20-1 and 20-2, the IP extension telephones 30-1 and 30-2, and the PHS extension telephone 40. Initially set as a phone. In addition, the legacy extension telephones 20-1 and 20-2, the IP extension telephones 30-1 and 30-2, and the PHS extension telephone 40 are located at the location where the person who uses the extension telephone normally exists (own seat position). The floor 1 is initially set as the seat position. It should be noted that whether or not to actually receive a group call is determined in consideration of the position information of the extension telephone described later.

  Here, the private branch exchange 10 stores and manages the location information corresponding to the IP address of the accommodated IP extension telephone 30 in the storage unit 14. For example, the private branch exchange 10 uses an IP extension telephone position information identification table T1 that can identify the value of the IP address registered for each extension telephone and the location information (specified by the NW address portion) of the IP address. By doing so, the position of the IP extension telephone 30 is managed.

  FIG. 3 is an explanatory diagram showing the correspondence between the IP address and the location information (IP extension telephone location information identification table T1).

  In the storage unit 14, for example, the relationship of the positional information associated with the NW address part of each IP address as shown in FIG. 3 is registered. For example, 192.168.1. The address of XX is the position information of “Office A Floor 1”, and is 192.168.99. The address of the AA is defined as location information of "outdoor".

  FIG. 4 is an explanatory diagram showing an example in which the IP address changes depending on the location (position) where the IP extension telephone 30-1 exists.

  The IP extension telephone 30-1 notifies the private branch exchange 10 of its own IP address information for terminal (telephone) information registration. If the IP address is updated when the IP extension telephone 30-1 (mobile terminal) moves, the IP address information after the update is notified to the private branch exchange 10. The private branch exchange 10 updates the IP address of each extension telephone in the storage unit 14 based on the notification.

  For example, as shown in the example of FIG. 4, the office A floor 1 is a position where the person who uses the IP extension telephone 30-1 normally exists (self-seat position), and this extension telephone exists at this location. Sometimes, the IP address of the IP extension telephone 30-1 managed by the private branch exchange 10 is 192.168.1.1.

  When the IP extension telephone 30-1 moves to the office A floor N, the IP address is re-registered in the private branch exchange 10 when the IP address changes, as in 192.168.2.30. Done. Hereinafter, even when the user moves to the office B or outdoors, the IP address is re-registered as shown in FIG.

  With respect to the table storing the relationship between the IP addresses managed by the private branch exchange 10 and the location information, in the example of FIG. 4, the private branch exchange 10 side fixes the location information name for each IP address notified by the IP extension telephone 30-1. In this case, the location information name may be appropriately reported, registered, and updated from the IP extension telephone to the private branch exchange. A detailed description of these will be given in the second embodiment section below.

  The private branch exchange 10 also manages the base station number of the accommodated PHS extension telephone 40.

  FIG. 5 is an explanatory diagram showing the correspondence between the PHS base station code and the location information (PHS extension telephone location information identification table T2).

  In the storage unit 14, the relationship of the location information associated with each PHS base station 60 is registered. For example, as shown in FIG. 5, the PHS base station code of 00001234 is the location information of the “office A floor 1”. It becomes.

  The PHS extension telephone 40 notifies the private branch exchange 10 of PHS base station information to which the PHS extension telephone belongs for terminal registration. When the PHS base station 60 to which the PHS extension telephone 40 (mobile terminal) moves has been updated, the PHS base station 60 notifies the private branch exchange 10 of the updated information. The private branch exchange 10 updates the PHS extension telephone management data in the storage unit 14 according to the notification. Note that each PHS base station 60 may report PHS base station information. In this case, when detecting the belonging of the new PHS extension telephone 40, the PHS base station 60 notifies the private branch exchange 10 of PHS base station information for terminal registration. If the PHS base station 60 does not notify the new PHS base station information of the new PHS extension phone 40 within a predetermined time after detecting the belonging of the new PHS extension phone 40, the PHS base station 60 May be notified of PHS base station information. The predetermined time is, for example, in the case of a PHS of TDMA / TDD (Time Division Multiple Access / Time Division Duplex) with four multiplexes (eight transmission / reception slots (four transmission slots + four reception slots in one frame)). A frame period in the PHS such as 5 ms, an integer multiple of the frame period in the PHS such as 10 ms, one slot in the frame period of the PHS such as 625 μs, an integer multiple of one slot in the frame period of the PHS such as 1250 μs, a PHS such as 2.5 ms (The time during which the PHS base station 60 receives a signal from the PHS extension telephone 40 (for four reception slots)).

  In the example shown in FIG. 6, in the PHS extension telephone 40, the business office A floor 1 is in a position where the user is normally located. The PHS base station code of the PHS extension telephone 40 managed by the private branch exchange 10 when it is present at this location is 00001234.

  Subsequently, when the PHS extension telephone 40 moves to the office A floor M and the belonging PHS base station changes, the private branch exchange 10 is re-registered with a new PHS base station code (000001235).

  As for the location information of the extension telephone to be used, instead of using the above-mentioned IP address and PHS base station information, the connection location of the extension telephone such as a MAC (Media Access Control) address or a GPS (Global Positioning System) is specified. Information that can be used may be used.

  The legacy extension telephone 20 is, for example, a conventional (non-IP) extension telephone connected to a private branch exchange by an analog extension telephone line or a digital multifunctional extension telephone line. Note that the analog extension telephone line is a line that transmits analog signals over metal wiring such as a two-wire analog line or a four-wire analog line. The digital multifunctional extension telephone line is a line for transmitting digital signals on a metal wiring such as a two-core wiring or a four-core wiring, and is, for example, an ISDN (Integrates Service Digital Network). The legacy (analog) accommodating I / F corresponds to a 2-wire analog line, a 4-wire analog line, and ISDN.

  The IP extension telephone 30 is an extension telephone connected by an IP network. The IP extension telephone 30 is exchanged with the private branch exchange 10 via the corporate IP network N2. When the IP extension telephone 30 accesses (remotely accesses) the in-house IP network N2 via the public IP network N1, from the viewpoint of security, for example, a virtual private network (VPN) or a firewall (FW) is used. , NAT (Network Address Translation), NAPT (Network Address Port Translation), RAS (Remote Access Service) server, and the like. In this embodiment, the public IP network N1 is assumed to be, for example, a public IP network such as 3G / LTE.

  The PHS extension telephone 40 is a business cordless extension telephone that is a mobile extension.

  The wireless LAN access point 50 is a radio repeater that accesses the corporate IP network N2 wirelessly connected by the IP extension telephone 30. For example, the wireless LAN access point 50 and the IP extension telephone 30 may perform wireless communication in a format based on IEEE 802.11 (wireless LAN).

  The PHS base station 60 is a base station wirelessly connected by the PHS extension telephone 40. For example, the PHS base station 60 and the PHS extension telephone 40 may perform wireless communication in a format compliant with RCR-STD28 (office cordless).

(A-2) Operation of First Embodiment Next, the operation of the private branch exchange system 1 according to the first embodiment (mainly the operation at the time of performing a group incoming call or a paging call) will be described with reference to the drawings. I do.

  FIG. 7 is a flowchart showing a procedure in which the private branch exchange 10 determines a destination of an extension telephone. Note that the process shown in FIG. 7 is always operating while the private branch exchange 10 is powered on, and ends when the power is turned off.

  The interface unit 11 of the private branch exchange 10 receives a connection request from an extension telephone or an external line (S101).

  Subsequently, the call processing unit 12 and the destination determination unit 13 of the private branch exchange 10 control the connection request (S102). First, the destination determination unit 13 of the private branch exchange 10 performs a dial analysis of this request. If the analyzed dial matches the special number of the group incoming call or general call stored in the storage unit 14, the position information of the extension telephone belonging to the special number is further analyzed. The analysis of the location information is obtained using the IP extension telephone location information identification table T1 or the PHS extension telephone location information identification table T2 in the storage unit 14. The destination determination unit 13 determines the destination when the location information of the telephone set to receive a call is the position information regarding the own seat. This determination of the destination is obtained by using the own position of the extension telephone in the storage unit 14. In this way, by dynamically judging from the instantaneous position information of the group incoming call, it is possible to prevent the useless incoming call to the extension telephone.

  The call processing unit 12 of the private branch exchange 10 performs call control on the destination determined by the above procedure (S103).

  If the analyzed dial does not match the special number for group incoming or paging stored in the storage unit 14, the destination determining unit 13 performs the same call control as before (S104).

  Here, the call control similar to the conventional one is control of the call processing without using the position information, which is different from the control of the call processing (S103) using the position information. For example, the extension telephone number of the IP extension telephone 30-1 is "301", the extension telephone number of the IP extension telephone 30-2 is "302", and the IP extension telephone 30-1 is connected to the IP extension telephone 30-2. This is when a request is made. When the call "302" for the IP extension telephone 30-2 is dialed in the IP extension telephone 30-1, the interface unit 11 of the private branch exchange 10 receives the connection request. Then, the destination determining unit 13 analyzes the dial, and the analyzed dial does not match the special number of the group incoming call or the general call stored in the storage unit 14, so that the call processing unit 12 performs the IP analysis via the IP network accommodating I / F. It controls call processing for establishing a call between the extension telephone 30-1 and the IP extension telephone 30-2. A call can be made between the IP extension telephone 30-1 and the IP extension telephone 30-2. That is, from the IP extension telephone 30-2, the call by “8-701” (the special number stored in the storage unit 14) and the call by “302” (the number different from the special number stored in the storage unit 14) are supported. When called by "8-701", the private branch exchange 10 (call processing unit 12) performs call processing using the location information, and when called by "302", the private branch exchange 10 (call processing unit 12). ) Performs call processing without using location information. The user of the IP extension telephone 30-2 performs a call process in accordance with the presence information (location information) in accordance with the called number of the telephone used by the user, thereby greatly increasing the convenience.

  FIG. 8 is an explanatory diagram showing a specific operation when a group call “8-701” for group A is dialed and executed.

  According to the location information of the extension telephones registered in the group A, the PHS extension telephone 40 is “office 1 floor M”, the IP extension telephone 30-1 is “outdoor”, and the IP extension telephone 30-2 is “office B”. (It does not exist at the group A's own position), the private branch exchange 10 excludes (exempts) these extension telephones from destinations.

  Then, the call to the group A for the office A floor 1 is determined to be received only at the legacy extension telephones 20-1 and 20-2, and is processed.

  Note that the destination determining unit 13 may determine the destination in further consideration of the terminal state. Specifically, the destination determining unit 13 analyzes the dial and analyzes the location information of the extension telephone to extract the destination, determines the terminal state of the extracted extension telephone as the destination, and determines that the telephone call is possible. Confirm only the extension phone as the destination. In this case, the private branch exchange 10 (storage unit 14) manages and stores terminal state information for each extension telephone to be accommodated, and the destination determination unit 13 has terminal state determination means for determining a terminal state. The terminal state information is, for example, as a state for each extension telephone, the legacy extension telephone 20-1 is “empty (waiting for incoming and outgoing calls.)”, And the legacy extension telephone 20-2 is “absent (legacy extension telephone 20-2 is on premises). The state in which call forwarding is set for the exchange 10.), the IP extension 30-1 is "vacant", the IP extension 30-2 is "vacant", and the PHS extension 40 is "calling (PHS extension). A state in which the telephone 40 is talking or a state in which the telephone 40 is on hold.) "). The terminal state determination means refers to the terminal state information for the destinations extracted by the destination determination unit 13 and determines whether the destination is “empty”. determine.

  For example, when dialing and executing the group call “8-701” for the group A in FIG. 8, the PHS extension telephone 40 is set to “business establishment 1 floor M” and the location information of the extension telephone registered in the group A. The IP telephone 30-1 is registered as “outdoor”, the IP telephone 30-2 is registered as “office B”, and the legacy telephone 20-2 is managed as “absent”. Are excluded (exempt) from the destinations.

  Then, the call to the group A for the office A floor 1 is determined to be received only at the legacy extension telephone 20-1, and is processed.

  Further, when this function is applied, a modified example in which a call specifying a calling place is performed is also possible.

  For example, when dialing a number for performing a group incoming call or a paging call, a special number is added to which, as additional information, a condition designation or the like outside of the user's seat is specified. Then, the caller dials according to the conditions. Then, the private branch exchange 10 can make an incoming call to the extension telephone in the designated position state. If the extension telephone does not exist at the designated position, for example, the private branch exchange 10 informs the caller by audible sound or guidance.

  FIG. 9 is an explanatory diagram showing a specific example of performing a group incoming call by designating a receiving place (presence).

  For example, suppose that the extension X dials a group call "8-701-5" (the last digit of the dial number is intended to designate a location) in which the group A designates only those who are "outdoors". Here, as for the last digit of the special number of the group incoming call, -1 is set in advance for the user's seat (floor 1), -2 is set for floor M, -3 is set for floor N, -4 is set for office B, and -5 is set for outdoor. Shall be.

  The private branch exchange 10 refers to the location information of the extension telephones registered in the group A and can identify that only the IP extension telephone 30-1 is registered outdoors. Therefore, only the IP extension telephone 30-1 is called. Is determined and processed. When the extension X dials the group call "8-701-1" in which only the person who is in the "own seat" in the group A is designated, the call destination is the same as that in FIG.

  Furthermore, by providing the private branch exchange 10 with a procedure (means) for registering and changing various states of the private telephone from each extension telephone to the private branch exchange 10, group identification based on attributes other than the location information is performed, and along with the identification group. Extensions such as incoming calls can also be made. Further, by providing a procedure (means) for publishing the contents changed in registration by a procedure (means) in which registration can be changed, it is also possible to make an extension such as notifying the sender of the registration change contents.

  For example, each extension telephone defines a special number for designating various states of its own extension telephone to the private branch exchange 10, and each extension telephone registers or changes by a special number dial according to the conditions. In addition, a caller who performs a group incoming call or a general call dials a number including the special number for specifying various conditions of a desired destination as additional information when dialing a number using these services. As described above, the private branch exchange 10 can receive an incoming call to the extension telephone set under the designated conditions. If the extension telephone does not exist at the designated position, for example, the private branch exchange 10 informs the caller of the extension by audible sound or guidance.

  For example, when a special number for designating various states of the local extension telephone is defined in the private branch exchange 10, and each extension telephone performs registration or change by a special number dial according to the conditions, the private branch exchange 10 is shown in FIG. Notify the registered or changed contents to a Web server that does not have a Web server including an HTTP server function provided in the corporate IP network N2 or a Web server including an HTTP server function provided in the public IP network N1. . The Web server forms and stores a home page including the notified registration and change contents. In response to the notification from the private branch exchange 10, the Web server uses HTML (HyperText Markup Language), XML (Extensible Markup Language), script (JavaScript (registered trademark), etc.) Form. Further, the Web server includes a Web container (Web container) function such as Apache Tomcat, and the Web server receives the notification from the private branch exchange 10 by the HTTP server function, and in response to the notification (registration or registration) (Contents of change) to the Web container function, and the Web container function may be controlled to automatically form a home page. Then, when a user (a sender who performs a group incoming call or a simultaneous call) makes a homepage browsing request using a PC or the like, the Web server receives the browsing request by the HTTP server function and returns the homepage in response to the browsing request. . Upon receiving the return from the Web server, the user can browse the home page displayed on a Web browser such as a PC. As described above, the private branch exchange 10 publishes the registered and changed contents (informs the user (caller)), and can receive a call to the extension telephone set under the specified conditions. If the extension telephone does not exist at the designated position, for example, the private branch exchange 10 informs the caller of the extension by audible sound or guidance.

  FIG. 10 is an explanatory diagram showing a state in which a special number for group reception including the attributes of extension telephones is set.

  For example, the IP extension telephone 30-2 belongs to the group A and registers "8-501-1" (8-501 is the extension telephone of the group A) in order to register that its own attribute is 1 in the private branch exchange. Attribute registration special number and the last digit of the dial number are intended for attribute designation, where -1 is attribute 1, -2 is attribute 2, -3 is attribute 3, and -4 is attribute 4. , -5 means attribute 5). Then, private branch exchange 10 registers IP extension telephone 30-2 as "attribute 1" based on the attribute information of the extension telephones registered in group A.

  The meaning of the attribute is defined by the user. For example, an attribute 1 such as -1 is "maintainable for device A", and an attribute 2 for -2 is "operable for device B".

  FIG. 11 is an explanatory diagram showing a specific example in which an attribute of an extension telephone is designated to perform a group incoming call.

  It is assumed that attribute registration as shown in FIG. 10 is set in the private branch exchange 10 in advance. In this state, for example, for the extension X, a group call “8-701-5-1” (“the second digit of the dial number is a place specification”) in which the “device A maintainable person” is designated “outdoor” for the group A is designated. The intention and the last digit are intended for attribute designation, and the meaning of "-5-1" is dialed for "outdoors" and "designation of" device A maintainable person ").

  In this case, the private branch exchange 10 checks the location information of the extension telephones registered in the group A and the state of the attribute status of the extension telephones, and only the IP extension telephone 30-2 is registered as "outdoor" and "device A". Since it has the "maintainable" attribute, it is determined that only the IP extension telephone 30-2 is to be called and processed.

  Also, "8-501-1" is dialed in the IP extension telephone 30-2, and the private branch exchange 10 sets the IP extension telephone 30-2 to "attribute 1" based on the attribute information of the extension telephone registered in the group A. If it is registered, the location information of the IP extension telephone 30-2 registered in the group A and the state of the attribute status of the extension telephone are checked, and “8-701-5-1” is extracted and registered in the Web server. And “8-701-5-1” as the content of the change. The Web server creates, stores, and publishes a home page including the notified “8-701-5-1”.

  The above usage example is for, for example, a caller searching for a serviceable person by a maintenance person outdoors to meet a need for a conference call in order to secure a maintenance person for the device A. It is.

  As described above, a telephone group having a desired attribute can be easily called only by dialing the telephone (no complicated operation), so that the convenience of the user is greatly enhanced.

  As described above, when a private branch exchange that performs call processing between terminals stores terminal location information and / or terminal attribute information and receives a call using the group called number, a ringing terminal is generated based on the terminal location information and / or terminal attribute information. Is automatically determined as a feature of the embodiment.

(A-3) Effects of First Embodiment According to the first embodiment, in a private branch exchange system in which the position of an extension telephone changes when a private branch exchange receives a group incoming call or a simultaneous call, incoming calls are not required. It is possible to avoid an incoming call to the extension telephone and efficiently communicate only with the other party that the caller wants to talk to, thereby improving user convenience.

(B) The following second embodiment, the private branch exchange according to the present invention, private branch exchange program, and the second embodiment of the PBX system will be described with reference to the drawings.

(B-1) Configuration, operation, and effect of the second embodiment The private branch exchange and the private branch exchange system of the second embodiment are also described with reference to FIGS. 1 to 5 similarly to the first embodiment. Can be shown. Hereinafter, the IP extension telephone 30 of the private branch exchange system 1 according to the second embodiment will be described focusing on differences from the first embodiment.

  In the first embodiment, the IP extension telephone 30 determines the current location according to the IP extension telephone location information identification table T1 shown in FIG. 3 when its own IP address changes. On the other hand, instead of this table, the IP extension telephone 30 of the second embodiment can determine the current position by transmitting necessary information. As will be described below, the private branch exchange 10 is a private branch exchange that supports the SIP (Session Initiation Protocol).

  When registering an IP address or the like in the private branch exchange 10, the IP extension telephone 30 generates a SIP protocol REGISTER message including its own IP address and extension number and transmits the message to the private branch exchange 10. The REGISTER message is repeatedly (periodically) transmitted to the private branch exchange 10. Further, as shown in FIG. 4 described above, when detecting a change in its own IP address due to movement, the IP extension telephone 30 transmits the REGISTER message to the private branch exchange 10. When the IP extension telephone 30 repeatedly (periodically) transmits the REGISTER message to the private branch exchange 10, the cycle may be changed depending on whether its own IP address is a global IP address or a private IP address. . For example, the IP extension telephone 30 has its own IP address of 10.10 based on RFC (Request for Comments) 1918. *. *. * Address, 172.16. *. * Address and 192.168. *. If it does not correspond to the address of *, it is determined that it is a global IP address, and a REGISTER message is transmitted at a period of 3600 seconds. On the other hand, if applicable, it is determined that the IP address is a private IP address, and a REGISTER message is transmitted at a cycle of 1800 seconds.

  When receiving the REGISTER message from the IP extension telephone 30, the private branch exchange 10 newly creates extension management status data of the IP extension telephone 30. If the extension management status data already exists, the extension management status data is updated.

  The private branch exchange 10 recognizes that communication with the extension telephone has been established by receiving the REGISTER message with the IP extension telephone 30. When the private branch exchange 10 cannot receive the REGISTER message from the IP extension telephone 30 for a predetermined time (for example, 10 to 3600 seconds), the private branch exchange 10 determines that communication with the IP extension telephone 30 has not been established, and changes the extension management state data. delete.

  Next, a specific example in which the IP extension telephone 30 transmits a REGISTER message will be described.

  When the IP extension telephone 30 acquires an IP address that can communicate with the private branch exchange 10 (for example, 192.168.1.1), the IP extension telephone 30 displays, for example, an initial screen as shown in FIG. FIG. 12 is a screen displayed on the IP extension telephone 30 for inputting extension management information to be registered. In the “server IP address” column of FIG. 12, the IP address of the private branch exchange 10 stored in the IP extension telephone 30 is displayed.

  In the “IP address” column of FIG. 12, the IP address of the private branch exchange 10 stored in the IP extension telephone 30 is displayed.

  In the “URI” (Uniform Resource Identifier) column of FIG. 12, the extension number of the IP extension telephone 30 itself stored in the IP extension telephone 30 is displayed.

  The “location information” field in FIG. 12 is an input field in which the user inputs the location information where the IP extension telephone 30 is located. For example, when the IP extension telephone 30 that has acquired the IP address of 192.168.40.10 exists “outdoor”, the user directly inputs “outdoor”.

  Further, in order to eliminate direct input of position information by the user, other alternative means may be implemented. For example, a selection button as shown in FIG. 13 may be implemented.

  FIG. 13A shows the initial state of the pull-down button located at the right end of the position information input field. When the user presses the pull-down button, a position information list (business establishment A floor 1, business establishment A floor N, business establishment B, outdoor) as shown in FIG. 13B is displayed.

  The list of these pieces of location information is registered in advance, but may be set, for example, when the call function (softphone) is installed in the IP extension telephone 30 or after the installation.

  When the call function (softphone) is installed in the IP extension telephone 30 or after the installation, it is checked whether or not the IP extension telephone 30 can be connected to the network. , You may download the latest list. In this case, the private branch exchange 10 previously stores the location information list (for example, the office A floor 1, the office A floor N, the office B, and the outdoors) as shown in FIG. Is downloaded to the IP extension telephone 30. Also, the private branch exchange 10 downloads the location information list from a server in the corporate IP network N2 or a server in the public IP network N1 not shown in FIG. 1, stores the location information list in the storage unit 14, You may make it download to the IP extension telephone 30. Further, the IP extension telephone 30 may repeatedly (periodically) download the latest list from the private branch exchange 10.

  When the user selects “outdoor” from the list, for example, “outdoor” is displayed (automatically input) in the position information input field as shown in FIG. 13C.

  The “OK” button in FIG. 12 is a button for confirming the contents input in each column of FIG. When the user presses the “OK” button, IP extension telephone 30 registers the input contents in private branch exchange 10. That is, the IP extension telephone 30 generates and transmits a REGISTER message including its own IP address, extension number, and location information with the server IP address as the destination. When the registration to the private branch exchange 10 is successful, the extension telephone 30 displays a call function screen (softphone screen). If the registration fails, the extension telephone 30 again displays the initial startup screen (FIG. 12) and prompts the user to register again.

  The “cancel” button in FIG. 12 is a button for canceling registration with the private branch exchange 10. That is, the IP extension telephone 30 does not transmit the REGISTER message.

  FIG. 14 is an explanatory diagram showing a specific example in which the IP extension telephone 30 registers position information and the like in the private branch exchange 10. This will be described by taking the IP extension telephone 30-1 existing outside in FIG. 4 as an example. For example, it is assumed that the IP extension telephone 30-1 has moved from its seat (facility A floor 1) to the outside. Then, IP extension telephone 30-1 transmits a REGISTER message including the acquired IP address and management information such as current location information (outdoor) to private branch exchange 10, as shown in FIG.

  The private branch exchange 10, which has received the REGISTER message, sets the location information management data stored in the storage unit 14 to the location information corresponding to the new IP address (192.168.40.10) as shown in FIG. (Outdoor) is newly added. Also, the private branch exchange 10 updates the IP address of the IP extension telephone 30-1 (extension number 2001) to a new IP address (192.168.40.10) for the extension telephone management data stored in the storage unit 14. .

  Next, an example in which the user freely updates the position information by performing a specific operation on the IP extension telephone 30 will be described. For example, there is a case where the IP address does not change even if the IP extension telephone 30 is moved (in other words, a case where a new IP address is not acquired). For example, even if the user moves from the floor 1 conference room A to the floor 1 conference room B, the access point on the floor 1 does not change, so that no new IP address is acquired. In such a case, if the user can freely update the location information of the IP extension telephone 30-1, the convenience is further improved. An example is shown below.

  For example, a “location information update” button is provided on the call function screen (softphone) of the IP extension telephone 30. When the user presses the position information update button, a position information update screen as shown in FIG. 15 is displayed on the IP extension telephone 30. When displaying the location information update screen as shown in FIG. 15, IP extension telephone 30 may download the latest list from private branch exchange 10.

  The user inputs the updated position information in the updated position information input field in FIG. 15 for the current position. Also, the pull-down button shown in FIG. 13 can be implemented in the update position information input field.

  The “OK” button in FIG. 15 is the same as the “OK” button in FIG. 12 described above, and a description thereof will be omitted.

  The “Cancel” button in FIG. 15 is the same as the “Cancel” button in FIG. However, the IP extension telephone 30 periodically transmits a REGISTER message (contents entered on the initial screen) for confirming communication with the private branch exchange 10.

  As described above, by providing the "location information update" button on the call function (softphone) screen of the IP extension telephone 30, it is possible to freely change the location (location) of the extension telephone, thereby providing more flexible operation. Can be made possible.

(C) the following third embodiment, private branch exchange according to the present invention, private branch exchange program, and an embodiment of a private branch exchange system will be described with reference to the drawings.

  In the first and second embodiments, in a private branch exchange system in which the position of an extension telephone changes at the time of group reception or simultaneous ringing of the private branch exchange, an incoming call to an extension telephone that does not need to be received is avoided, and An example has been described in which a call can be efficiently made only with the other party who wants to talk. On the other hand, in the third embodiment, an example is described in which an incoming call to an extension telephone that does not require an incoming call is avoided (an incoming call is transmitted to an extension telephone that requires an incoming call), and the call is rescued if a call is not established. Show. The reason why the telephone call is not established corresponds to the reason that the extension telephone rings (receives an incoming call) but does not respond, the extension telephone fails, the extension telephone is busy, and the like. Call rescue is to improve the possibility of making a call. In other words, the third embodiment is a mode in which the call blocking rate is improved as compared with the first and second embodiments.

(C-1) Configuration of Third Embodiment The configuration of the private branch exchange and the private branch exchange system of the third embodiment can be shown using FIGS. 1 to 5 as in the first embodiment. . Hereinafter, the configuration of the private branch exchange 10 according to the third embodiment will be described focusing on differences from the first embodiment.

  The destination determination unit 13 of the first embodiment determines the destination by performing dial analysis and analysis of the location information of the extension telephone. Then, the call processing unit 12 performs the call control on the destination determined by the destination determining process of the destination determining unit 13.

  On the other hand, the destination determination unit 13 of the third embodiment determines the destination by performing the dial analysis and the analysis of the location information of the extension telephone, and after the call processing unit 12 performs call control on the determined destination. If the call is not established within a predetermined time, the "call destination correction process" is performed. Here, the destination correction processing is processing for correcting the destination for a connection request to which the destination determination processing is applied. That is, when a call is not established at the destination determined in the destination determination processing, the destination determination unit 13 determines a new destination in the destination correction processing, so that the call loss rate can be improved. Although the destination determined by the destination determining process is different from the destination determined by the destination correcting process, the operation including this point will be described later.

(C-2) Operation of Third Embodiment Next, the operation of the private branch exchange system 1 according to the third embodiment having the above-described configuration will be described with reference to the drawings. Hereinafter, a specific example of the operation of the private branch exchange system 1 according to the third embodiment when the group call “8-701” for the group A is dialed and executed as in the first embodiment (FIG. 7, FIG. 8). In the private branch exchange system 1 according to the third embodiment, the conditions such as the own seat position of the extension telephone, the PHS extension telephone location information identification table T2, and the IP extension telephone location information identification table T1 are the same as those of the first embodiment. The same shall apply.

  First, when "8-701" (group call for group A) is dialed at extension X (FIG. 8), the interface unit 11 of the private branch exchange 10 receives a connection request (S101).

  The destination determination unit 13 of the private branch exchange 10 performs a dial analysis of the request, and if the analyzed dial matches the special number (group call or paging) stored in the storage unit 14 (S102), the call destination determination unit 13 further specifies the special number. The location information of the extension telephones to which the PHS extension telephones 40 belong is determined by analyzing only the legacy extension telephones 20-1 and 20-2. 1 floor M ", the IP extension 30-1 is registered as" outdoor ", and the IP extension 30-2 is registered as" office B "(not present at the group A's own seat). Is determined to be out of the target (excluded) from the destination (reception destination determination processing) (S103). Then, the call processing unit 12 controls the call processing for the determined destination. Subsequent operations are operations specific to the private branch exchange system 1 of the third embodiment.

  Here, the call processing unit 12 starts counting a predetermined time (for example, 5 seconds) after performing the call control on the destination determined in the destination determination processing.

  When the extension X makes a connection request and the call processing unit 12 controls the call processing, the legacy extension telephones 20-1 and 20-2 receive an incoming call and ring.

  When the ringing legacy extension telephone set 20-1 or 20-2 answers within a predetermined time (for example, within 1 to 5 seconds), a call is made with the extension X.

  On the other hand, if the ringing legacy extension telephone 20-1 or 20-2 does not answer and exceeds a predetermined time (for example, exceeds 5 seconds), the call processing unit 12 sends a call destination correction unit 13 to the call destination determination unit 13. Perform processing.

  The destination determining unit 13 determines a new destination in the destination correction process. Here, as the destination correction processing, the destination determining unit 13 can apply the following three processing methods.

  In the first processing method, the same call control (control of call processing without using position information) (S104) is applied as the destination correction processing.

  In this case, as described above, the destination determination unit 13 first determines that only the legacy extension telephones 20-1 and 20-2 are destinations (destination determination processing) (S103), and the call processing unit 12 is determined. The call processing is controlled for the called destination, and counting of a predetermined time is started. When the ringing legacy extension telephone 20-1 or 20-2 does not answer and exceeds the predetermined time, the call processing unit 12 determines the called destination. It causes the unit 13 to perform a destination correction process. Here, the destination determination unit 13 to which the destination correction processing of the first processing method is applied is a legacy extension telephone set 20-1, 20-2, which is an extension telephone belonging to the special number (the number dialed at the extension X). The IP extension telephones 30-1 and 30-2 and the PHS extension telephone 40 are determined as destinations (all the extension telephones registered in the group A are determined as destinations) (destination correction processing). Then, the call processing unit 12 controls the call processing for the destination determined by the destination correction processing.

  The second processing method applies call control by an automatic voice response device (IVR) as a destination correction process.

  In this case, as described above, the destination determination unit 13 first determines that only the legacy extension telephones 20-1 and 20-2 are destinations (destination determination processing) (S103), and the call processing unit 12 is determined. The call processing is controlled for the called destination, and counting of a predetermined time is started. When the ringing legacy extension telephone 20-1 or 20-2 does not answer and exceeds the predetermined time, the call processing unit 12 determines the called destination. It causes the unit 13 to perform a destination correction process. Here, the destination determining unit 13 to which the destination correction processing of the second processing method is applied is disposed in the automatic voice response apparatus (the private branch exchange 10 or the corporate IP network) not shown in FIG. ) Is determined as a destination (destination correction processing). Then, the call processing unit 12 controls the call processing for the destination determined by the destination correction processing. When the automatic voice response apparatus automatically answers, the extension (X) on the calling side is provided with guidance (for example, voice notifying that the current call cannot be answered or redialing to another number). The automatic voice response apparatus may receive and store a voice message (answering machine) from extension X.

  The third processing method is to apply call control by slide incoming as the destination correction processing.

  In this case, as described above, the destination determination unit 13 first determines that only the legacy extension telephones 20-1 and 20-2 are destinations (destination determination processing) (S103), and the call processing unit 12 is determined. The call processing is controlled for the called destination, and counting of a predetermined time is started. When the ringing legacy extension telephone 20-1 or 20-2 does not answer and exceeds the predetermined time, the call processing unit 12 determines the called destination. It causes the unit 13 to perform a destination correction process. Here, the destination determination unit 13 to which the destination correction processing of the third processing method is applied is a representative telephone (premise telephone) not shown in FIG. 1 other than the extension telephone belonging to the special number (the number dialed at the extension X). A determination is made that the representative telephone on the floor 1 stored in the exchange 10 in advance is the destination (a destination other than the currently ringing extension telephone is determined as the destination) (destination correction processing). Then, the call processing unit 12 controls the call processing for the destination determined by the destination correction processing. When the ringing representative telephone answers, a call is made with extension X.

  Hereinafter, in the description of the operation of the third embodiment, the destination correction processing to which the first processing method is applied will be described in further detail.

  The destination deciding unit 13 uses the legacy extension telephones 20-1 and 20-2, the IP extension telephones 30-1 and 30-2, and the PHS extension telephone 40 (registered in the group A) as new destinations in the destination correction processing. Are determined to be destinations.

  The call processing unit 12 controls call processing for the determined destination. Here, the call processing unit 12 does not count the predetermined time after performing the call control on the destination determined in the destination correction process.

  When the extension X makes a connection request and the call processing unit 12 controls the call processing, the legacy extensions 20-1, 20-2, the IP extensions 30-1, 30-2, and the PHS extension 40 are connected. Incoming and ringing.

  The destination determination unit 13 may determine the destination by the destination correction process when the destination cannot be determined in the destination determination process. When the destination is not determined in the destination determining process, the destination determining unit 13 analyzes the dial and analyzes the location information of the extension telephone, and when the destination cannot be determined, the destination determining unit 13 performs the dial analysis and the extension. The location information of the telephone is analyzed to extract the destination, the terminal state of the extension telephone extracted as the destination is determined, and the extension telephone determined to be callable cannot be determined as the destination.

  For example, in FIG. 8, in the situation where the legacy extension telephones 20-1 and 20-2 are removed due to a failure (the private branch exchange 10 does not accommodate the legacy extension telephones 20-1 and 20-2), the office A floor When a call is made to the group A for the callee 1, the destination determination unit 13 analyzes the dial and analyzes the location information of the extension telephone and cannot determine the destination. It operates so that can be determined. In this case, the destination determining unit 13 determines that the IP extensions 30-1 and 30-2 and the PHS extension 40 that are the extension telephones belonging to the special number in the destination correction processing of the first processing method are the destinations (legacy extensions). All the extension telephones registered in the group A except for the telephones 20-1 and 20-2 are determined as the destinations), or the automatic voice response apparatus is determined as the destination by the destination correction processing of the second processing method. Alternatively, the representative telephone is determined to be the destination in the destination correction process of the third processing method.

  For example, in FIG. 8, when a call is made to the group A targeting the office A floor 1 in a situation where the legacy extension telephones 20-1 and 20-2 are in a call, the destination determination unit 13 When the destination is extracted by analyzing the dial and analyzing the location information of the extension phone, the terminal status determination means determines that the call is not possible and the destination cannot be determined. Works to be able to. In this case, the destination determining unit 13 determines that the IP extensions 30-1 and 30-2 and the PHS extension 40 that are the extension telephones belonging to the special number in the destination correction processing of the first processing method are the destinations (legacy extensions). All the extension telephones registered in the group A except for the telephones 20-1 and 20-2 are determined as the destinations), or the automatic voice response apparatus is determined as the destination by the destination correction processing of the second processing method. Alternatively, the representative telephone is determined to be the destination in the destination correction process of the third processing method.

  As described above, the destination determining unit 13 performs the destination determining process and the destination correcting process, so that the incoming call to the extension telephone that does not need to be received can be avoided (the incoming call can be received to the extension telephone that needs to be received). If the call is not established, the call can be rescued.

(C-3) Effects of Third Embodiment According to the third embodiment, in addition to the effects of the first embodiment, when the other party who wants to call does not answer, the callee is automatically changed and the call is terminated. It is possible to improve the possibility of performing, and it can be expected to improve the convenience of the user.

(D) Other Modified Embodiments In addition to the above-described embodiments, the following modified embodiments can be further exemplified.

  (D-1) As a mode different from the mode of applying the call processing using the location information to the telephone connection request as in the first embodiment, the location information corresponding to the IM (Instant Messaging) transmission request is transmitted. The technical idea of the present invention can be applied to the used transmission processing. The IM exchanges (transmits and receives) messages between terminals. For example, assuming that the private branch exchange system 1 in FIG. 1 is an IM compatible system, the IP extension telephone 30-1 transmits a message (character string, moving image, audible sound, etc.) and a transmission destination (extension telephone number of the IP extension telephone 30-2). When the IM transmission request including “302”) is sent, the private branch exchange 10 receives the IM transmission request and transfers the message to the transmission destination, and the IP extension telephone 30-2 receives the message from the private branch exchange 10.

  In this case, the call processing unit 12 controls transmission processing for an IM transmission request from a public network or an extension telephone. Further, the destination determining unit 13 determines a message transfer destination based on the IM transmission request. As a result of analyzing the destination in the IM transmission request, if the destination is a specific destination, the destination determining unit 13 associates the destination with the specific destination by taking into account the location information of the extension telephone of the destination. One or more attached telephones are determined as message transfer destinations. In addition, the storage unit 14 stores the extension telephones accommodated by the private branch exchange 10 and their own seat positions (for example, the IP extension telephones 30-1 and 30-2 have their own positions on the office A floor 1) and a specific transmission destination (for example, Data such as “301” and “302”), IP extension telephone location information identification table T1 (FIG. 3), and PHS extension telephone location information identification table T2 (FIG. 5) are stored.

  Hereinafter, the operation of the IM-compatible private branch exchange system 1 will be described with reference to the flowchart of FIG. 7 described above.

  When the IP extension telephone 30-1 sends an IM transmission request including a message and a destination ("302"), the interface unit 11 of the private branch exchange 10 receives the IM transmission request from the extension telephone or an external line (S101).

  Subsequently, the call processing unit 12 and the destination determination unit 13 of the private branch exchange 10 control the IM transmission request (S102). First, the destination determining unit 13 of the private branch exchange 10 analyzes the destination of this request. When the analyzed transmission destination matches the specific transmission destination stored in the storage unit 14, the location information of the extension telephone (the IP extension telephone 30-2 corresponding to “302”) further belonging to the specific transmission destination is displayed. Perform analysis. The analysis of the location information is obtained using the IP extension telephone location information identification table T1 or the PHS extension telephone location information identification table T2 in the storage unit 14. The destination determination unit 13 determines the transfer destination when the location information of the extension telephone to be received is, for example, the location information relating to the user's own seat (the location information of the IP extension telephone 30-2 is the same as that of the IP extension telephone 30-2). If it is the office A floor 1 which is the seat position, it is determined as the transfer destination).

  The call processing unit 12 controls transmission processing for the determined transfer destination (S103). If the destination determined by the destination determining unit 13 does not match the specific destination stored in the storage unit 14, the control of the transmission process (the destination ("302")) is performed in the same manner as in the related art. Is performed (S104). In addition, the location information of the extension telephone to be received by the destination determination unit 13 is not the location information on the own seat (the location information of the IP extension phone 30-2 is the office where the IP extension phone 30-2 is the own seat). If it is determined that the extension telephone is not (A floor 1), the call processing unit 12 does not perform transmission processing (transfer) for the extension telephone. In this way, by dynamically determining the IM based on the instantaneous position information, it is possible to prevent unnecessary IM to the extension telephone.

  (D-2) As a mode different from the mode of applying the call processing using the position information to the telephone connection request as in the first embodiment, the position information for the presence information distribution request in the presence management system is different. The technical idea of the present invention can also be applied to a distribution process using. The presence management system exchanges (transmits and receives) presence information between terminals. For example, assuming that the private branch exchange system 1 in FIG. 1 is a presence management compatible system, the extension X is the presence information (for example, the situation of the user of the IP extension telephone 30-1 such as during a conference, busy, or calling) and the distribution destination. (For example, “XYZ”), the private branch exchange 10 receives the presence information distribution request, transfers the presence information to the extension telephone corresponding to the distribution destination, and the private branch exchange 10 transmits the presence information from the private branch exchange 10. It receives information.

  In this case, the call processing unit 12 controls distribution processing for a presence information distribution request from a public network or an extension telephone. The destination determining unit 13 determines a destination of the presence information based on the presence information distribution request. As a result of analyzing the distribution destination in the presence information distribution request, if the destination is a specific distribution destination, the destination determination unit 13 considers the location information of the extension telephone of the distribution destination, and One or more associated telephones are determined as the presence information distribution destinations. Further, the storage unit 14 stores the extension telephones accommodated by the private branch exchange 10 and their own seat positions (for example, the IP extension telephones 30-1 and 30-2 locate themselves on the office A floor 1) and a specific distribution destination (for example, "XYZ"), IP extension telephone location information identification table T1 (FIG. 3), PHS extension telephone location information identification table T2 (FIG. 5), and the like. Note that, for the specific distribution destination “XYZ”, the IP extension telephones 30-1 “301” and 30-2 “302” are initially set as distribution destination telephones, and the presence information including the presence information and the distribution destination “XYZ” is included. By transmitting the information distribution request, the presence information is distributed to the IP extension telephones 30-1 and 30-2.

  Hereinafter, the operation of the private information exchange system 1 corresponding to the presence information will be described with reference to the flowchart of FIG.

  When the extension X sends a presence information distribution request including the presence information and the specific distribution destination ("XYZ"), the interface unit 11 of the private branch exchange 10 receives the presence information distribution request from the extension telephone or an external line (S101).

  Subsequently, the call processing unit 12 and the destination determination unit 13 of the private branch exchange 10 control the presence information distribution request (S102). First, the destination determining unit 13 of the private branch exchange 10 analyzes the distribution destination of this request. If the analyzed distribution destination matches the specific distribution destination stored in the storage unit 14, the distribution destinations further extend to the extension telephones (IP extension telephones 30-1 and 302 corresponding to "301") belonging to the specific distribution destination. The location information of the corresponding IP extension telephone 30-2) is analyzed. The analysis of the location information is obtained using the IP extension telephone location information identification table T1 or the PHS extension telephone location information identification table T2 in the storage unit 14. When the location information of the extension telephone to be received is the location information relating to the user's own seat, the destination determination unit 13 determines the transfer destination (the location information of the IP extension telephones 30-1 and 30-2 is the IP extension telephone). If it is the office A floor 1 that is the own seat position of 30-1 and 30-2, it is determined to be the distribution destination).

  The call processing unit 12 controls distribution processing for the determined distribution destination (S103). If the transmission destination analyzed by the destination determination unit 13 does not match the specific transmission destination stored in the storage unit 14, control of distribution processing similar to that of the related art (distribution destinations ("301", "302 )) Is performed (S104). Further, the location information of the extension telephone to be received by the destination determination unit 13 is not the location information on the own seat (the location information of the IP extension phone 30-1 is the location of the IP extension phone 30-1 where the own seat is located). When it is determined that the extension telephone is not (A floor 1), the call processing unit 12 does not perform the distribution process (delivery) for the extension telephone. As described above, by dynamically determining the presence information based on the instantaneous position information, it is possible to prevent the presence information from being delivered to unnecessary extension telephones.

  (D-3) As a mode different from the mode in which the call processing unit 12 controls call processing for a connection request from a public network or an extension telephone as in the first embodiment, the call processing unit 12 A modification in which call processing control is performed only for a connection request from the (outside line network) is conceivable. Since the inside of the office A and the public network side (external line network side) are physically separated, it is difficult for the public network side (external line network side) to know the state and the state of the floor 1 and the like in the office A. is there. Therefore, there is a possibility that a connection request from the public network side (external line network side) may increase the number of incoming calls to an unnecessary extension telephone.

  In this case, the private branch exchange 10 has a filter means, and determines whether to perform a group incoming call or a paging call for a line identification for each I / F and a connection request flowing in for each I / F. Hereinafter, the operation of the private branch exchange system 1 in which the private branch exchange 10 has the filter means will be described with reference to the flowchart of FIG. 7 described above.

  For example, the private branch exchange 10 (the call processing unit 12) determines that a group incoming call or a paging call is to be performed when the filter unit determines that the connection request has flowed in through the external line accommodating I / F.

  The private branch exchange 10 (the call processing unit 12) flows into the filter means via another I / F (any of a legacy (analog) accommodation I / F, an IP network accommodation I / F, and a PHS accommodation I / F). If it is determined that the connection request has been made, it is determined that the group incoming call or the simultaneous call is not performed.

  Then, the private branch exchange 10 (the call processing unit 12) performs the call processing (S103) using the position information for the connection request flowing through the external line accommodating I / F.

  On the other hand, call control similar to the conventional one is performed for a connection request flowing through any of the legacy (analog) accommodation I / F, the IP network accommodation I / F, and the PHS accommodation I / F (S104).

  In other words, the private branch exchange 10 applies the call processing (S103) using the position information only to the connection request from the public network (external network side), and the other I / F (legacy (analog) accommodating I / F). F, one of the IP network accommodating I / F and the PHS accommodating I / F), the same call control (S104) as in the related art is applied to the connection request that flows in.

  (D-4) As a mode different from the mode of the first embodiment in which the call processing unit 12 controls call processing for a connection request from a public network or an extension telephone, the call processing unit 12 is authenticated. A modified example in which call processing is controlled only for a connection request relating to a caller who has made a call is considered.

  In this case, the private branch exchange 10 has an authentication unit, authenticates a connection request flowing in for each I / F, and determines whether to perform a group incoming call or a paging call. Hereinafter, the operation of the private branch exchange system 1 in which the private branch exchange 10 has an authentication unit will be described with reference to the flowchart of FIG. 7 described above.

  When performing control (S102) in the call processing unit 12 and the destination determination unit 13 of the private branch exchange 10, authentication is performed by an authentication unit. First, the destination determination unit 13 of the private branch exchange 10 performs a dial analysis of this request. If the analyzed dial matches the special number of the group incoming call or general call stored in the storage unit 14, the sender is authenticated by the authentication means, and if the authentication succeeds, the location information of the extension telephone belonging to the special number is further obtained. Perform analysis. On the other hand, if the authentication is performed and the authentication is failed and the authentication fails, the private branch exchange 10 (call processing unit 12) terminates the call (disconnects the connection request and shifts to a request reception (S101) wait). When the caller authentication fails in the authentication means, the call may be terminated after notifying the caller that the private branch exchange 10 cannot process the message with guidance or the like.

  Here, as the authentication means, either a caller number authentication process for authenticating with a caller number or a password authentication process for authenticating with a password can be applied. When the caller number authentication process is applied, the storage unit 14 stores the caller number list, the destination determination unit 13 analyzes and obtains the caller number in accordance with the dial analysis of the request, and the authentication unit sets the caller number list. And the caller ID. If the caller ID is not included in the caller ID list, the authentication is determined to be successful.If the caller ID is not included in the caller ID list, the authentication is determined to have failed. (Caller ID authentication processing). When the password authentication processing is applied, the storage unit 14 stores a password list, and the destination determination unit 13 prompts the input with guidance or the like separately from the connection request in accordance with the dial analysis of the request, and prompts the caller to input the password. (Password specification)) is analyzed and obtained, and the authentication means checks the password list against the password. If the password is included in the password list, it is determined that the authentication is successful. If the password is not included in the password list, the authentication is successful. Judge that authentication failed (password authentication process).

  (D-5) As described above, the PBX that performs the call processing between the terminals stores the terminal location information and / or the terminal attribute information, and performs the transmission, the IM transmission, and the presence distribution by the specific transmission destination (including the group reception number). A feature of the present application is that when a request is received, a called terminal is automatically determined based on terminal location information and / or terminal attribute information, and when a terminal cannot be answered, a call rescue process is performed.
