Description

  The present invention provides, for example, a telephone system formed by connecting a plurality of telephone control apparatuses that can accommodate a plurality of telephones through a wide area network, a telephone control apparatus constituting the telephone system, and a system used in the telephone system. It relates to information setting method.

  In recent years, a button telephone system (business phone system) corresponding to an IP telephone capable of making a call via an IP network (IP communication network) has been provided. Here, the key telephone system means a so-called private telephone system that is formed in a premises such as a company by a main apparatus (telephone control apparatus) and a plurality of dedicated telephones. In addition, the IP telephone performs voice communication by converting voice into a packet according to the Internet protocol by VoIP technology and transmitting / receiving the packet via the IP network (mainly the Internet). Since the IP telephone uses the IP network, the communication cost can be reduced.

  A button telephone system compatible with IP telephones, for example, by connecting a telephone telephone system of a head office and a branch office that are geographically distant from each other so that an extension call can be made between the head office and the branch office. Has been done. In order to connect the button telephone systems through the IP network, it is necessary to register in advance the address data (IP address, etc.) of the main apparatus of the other button telephone system for each main apparatus of the button telephone system. is there. Conventionally, a construction worker or the like manually registers address data in the main apparatus.

  However, it would be troublesome and time consuming if the person in charge of construction registered the address data to the main device manually. In particular, as the number of button telephone systems to be connected increases, the address data of the unregistered key telephone system main unit is sent to both the newly added main unit of the key telephone system and the main unit of the existing button telephone system. It takes time because you have to register. Patent Document 1 described later as an improvement measure discloses an invention for acquiring address data of another button telephone system by out-of-band communication of a DTMF (Dual Tone Multi Frequency) signal.

  In the invention described in Patent Document 1, first, a telephone number assigned to a main apparatus of another button telephone system is registered for the main apparatus of each button telephone system. If a communication path through the IP network is not connected to another main apparatus, a DTMF (Dual Tone Multi Frequency) signal is output when a call is made to the target main apparatus. The address data assigned to the target main device is acquired by band communication. Using this acquired address data, a communication path is connected to another main apparatus through the IP network.

  As described above, in the invention described in Patent Document 1, a telephone line that is used in a fixed manner is used to make a call to the main device of the target button telephone system to connect the telephone line, and the telephone line is connected through the telephone line. The address data assigned to the main device can be obtained automatically. That is, it becomes possible to collect and register the address data of the main device of another key telephone system without bothering the person in charge of the construction work. In addition, for example, even when the address data assigned to the main device of the key telephone system changes due to the influence of a power failure or the like, it is convenient because the address data can be easily reacquired.

JP 2011-071868 A

  By the way, it is not only the address data that is necessary to connect the key telephone systems through the IP network. It is also necessary to register a numbering plan (use plan for extension numbers, etc.) for each key telephone system. If not only the numbering plan of the own system but also the numbering plan of other systems are registered in the main device of each key telephone system, a so-called extension call cannot be performed between the key telephone systems. For this reason, the number plan of the button telephone system of the other party is collected using the DTMF signal out-band communication through the telephone line connected by making a call to the other party using the technique described in Patent Document 1. Is also possible.

  However, since the out-of-band communication of the DTMF signal is voice communication, there is a problem that it takes time to transmit data such as a numbering plan. In the case of the technique described in Patent Document 1, in order to connect the button telephone systems through the IP network, first, a predetermined button telephone system is connected to another button telephone system that connects a communication path through the IP network. You need to make a phone call to get address data. As described above, a process of making a telephone call, connecting a telephone line, and acquiring address data is necessarily required, and a procedure for connecting a communication path through an IP network is somewhat complicated. Further, when the situation of making a call to the target key telephone system does not occur, the communication path cannot be connected through the IP network.

  In addition, it is desirable to adopt the closed number system rather than the open number system in order to make it possible to easily make an extension call between the respective button telephone systems that connect the communication path through the IP network. The open number method is a method of making an extension call by specifying a destination by a system number + extension number. The system number is a number for identifying a system such as “# 1, # 2,...”, And the extension number is an extension number in each button telephone system such as “1000, 1001,. In the case of the open number system, since the system number is used, the same extension number can be used in each key telephone system. That is, when the extension number “1000” is used in the key telephone system at the head office, the same extension number “1000” can be used in the button telephone system at the branch office. An invention related to a button telephone using an open number number plan is disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-266554.

  On the other hand, the closed number system uses an extension number (a non-overlapping extension number) that is unique to all the button telephone systems that connect the communication path through the IP network without using the system number. For this reason, it is possible to make an extension call by simply dialing a unique extension number without distinguishing between extension telephones in a button telephone system and extension telephones between button telephone systems. However, in the case of the closed number system, the same extension number is used in each button telephone system except for the so-called extension special number (extension special number) that is commonly used in each button telephone system in order to use an extension number unique among the button telephone systems. Cannot be used in duplicate. For this reason, when a communication path is connected between the key telephone systems through the IP network, it is necessary to be able to easily register the number plan of the closed number system in each key telephone system in addition to the address data. .

  In view of the above, the present invention provides, for example, address data required by each button telephone system and, for example, closed number number plan data, for each of a plurality of button telephone systems connected through a network such as an IP network. It is an object of the present invention to be able to properly register system information such as, and to facilitate connection between key telephone systems through a network.

In order to solve the above-mentioned problem, the telephone system according to the first aspect of the present invention provides:

Connection request means for requesting connection by providing address data of the own device to the master telephone control device specified by the address data of the master telephone control device of the master information storage means, To do.

  According to the telephone system of the first aspect of the present invention, the telephone system includes the master telephone control device and the slave telephone control device. The master telephone control device includes storage means for storing system information. Predetermined system information is provided in advance and registered in the storage means by the first registration means. When a connection request including address data is received from the slave telephone control device, the address data is registered in the storage means by the second registration means.

  Further, in the master telephone control device, the first and second distribution means function after the registration processing by the second registration means. That is, the first distribution means distributes system information about each of the plurality of telephone control devices constituting the telephone system to the slave telephone control device that is the connection request source. In addition, the second distribution means distributes system information about the slave telephone control device of the connection request source to each of the slave telephone control devices other than the connection request source.

  On the other hand, the slave telephone control device is provided with system information storage means, and predetermined system information is provided in advance and registered in the system information storage means by the registration means. Further, the registration information in the system information storage unit is updated by the updating unit based on the system information transmitted from the master telephone control apparatus through the IP network. In the slave telephone control device that is the connection request source, at least address data of the master telephone control device is held in the master information storage means. Then, the connection request means uses the address data of the master telephone control device of the master information storage means so that the master telephone control device can be provided with its own address data to request connection.

  Hereinafter, embodiments of the system, apparatus, and method of the present invention will be described with reference to the drawings. In the embodiment described below, main devices (telephone control devices) installed at geographically distant locations are connected to each other through a wide area network such as a telephone network or an IP network provided by a telephone company. An example of a telephone system will be described.

[Example of telephone system configuration]
FIG. 1 is a diagram for explaining a configuration example of a telephone system according to this embodiment, and is configured by applying one embodiment of a telephone system according to the present invention. As shown in FIG. 1, the telephone system of this embodiment includes a main apparatus installed at geographically distant locations such as a head office (Tokyo), a branch office 1 (Tohoku), a branch office 2 (Kansai), and so on. (Telephone control devices) 1A, 1B, 1C,... Are configured to be connectable by a wide area network 200 including an IP network 200A and a telephone network 200B.

  In FIG. 1, an IP network 200A means a network through which data packetized according to the Internet protocol is transmitted and received, and is mainly the Internet. The telephone network 200B is provided by a telephone company or the like such as a public switched telephone network, a mobile telephone network, an optical telephone network, and includes various communication networks for telephone communication that will be provided in the future.

  The main apparatus 1A includes telephones 2A (1), 2A (2),..., The main apparatus 1B includes telephones 2B (1), 2B (2),. ), 2C (2),... Are connected through a LAN (Local Area Network). As a result, at the head office and each branch office, a key telephone system is configured by the main apparatus and the telephone connected to the LAN.

  In this specification, for example, a button telephone system at a head office or a button telephone system at a branch office, for example, a system related to a telephone formed on the same premises with one main device as a connection end to the wide area network 200 is buttoned. It is called a telephone system. A system related to a telephone formed over a wide area by connecting a plurality of main devices 1A, 1B, 1C,... Through the wide area network 200 is simply referred to as a telephone system.

  In the telephone system of this embodiment, the main device 1A installed at the head office is the master main device (master telephone control device), and the main devices 1B, 1C,. Slave telephone control device). When each of the main apparatuses 1A, 1B, 1C,... Accesses the telephone company ISP (Internet Service Provider) for the first time, an IP address is assigned by the ISP server, and connection to the IP network 200A is made. An environment is possible.

  In this embodiment, in order to simplify the description, the main apparatuses 1A, 1B, 1C,... Do not change even when the connection to the IP network 200A is cut off, for example, by turning off the power. It is assumed that a fixed IP address is assigned. Of course, a dynamic IP address can also be used. However, when a dynamic IP address is used, it is necessary to re-establish a connection of a communication path through the IP network 200A by making a connection request to the telephone system described later every time the dynamic IP address changes. Arise.

  And only by assigning IP addresses to the main apparatuses 1A, 1B, 1C,..., The main apparatuses cannot be connected through the IP network 200A. The main devices that connect the communication path through the IP network 200A need to know each other's IP address. This is because the communication path specifying the other party cannot be connected unless the other party is known.

  Therefore, in the telephone system of this embodiment, for the slave main unit that has not established a communication path connection with the master main unit 1A through the IP network 200A, the IP address of the master main unit 1A is set. sign up. The master main apparatus 1A is accessed (logged in) from the slave main apparatus through the IP network 200A using the IP address of the master main apparatus registered in advance, and the IP address of the slave main apparatus is provided to the master main apparatus 1A And request a connection. As a result, the master main apparatus 1A can acquire and store the IP address of the slave main apparatus that is the connection request source, and can connect a communication path between the slave main apparatus and the master main apparatus 1A. .

  Further, the master main apparatus 1A provides the IP address of another slave main apparatus that has already connected the communication path through the IP network 200A to the slave main apparatus that is the connection request source. Further, the master main apparatus 1A provides the IP address of the slave main apparatus that is the connection request source to other slave main apparatuses that are already connected to the communication path through the IP network 200A other than the connection request source. . As a result, communication paths can be mutually connected through the IP network 200A between the slave main units through the IP network 200A. In this way, communication paths can be connected between the main apparatuses through the IP network 200A so that a call can be made through the IP network 200A.

  The connection of the communication path between the slave main apparatuses may be performed by accessing the other slave main apparatus through the IP network 200A from the slave main apparatus of the current connection request source and connecting the communication paths. Of course, the slave main apparatus other than the current connection request source may access the slave main apparatus of the current connection request source through the IP network 200A and connect the communication path.

  However, if there are a plurality of slave main devices already connected to the master main device 1A through the IP network 200A, a plurality of connection requests are made to the slave main device of the current connection request source. It can also occur at the same time. Therefore, in order to prevent the connection request from being generated at the same time as the connection request source slave main unit, a method of accessing the other slave main unit from the connection request source slave main unit is proposed. Use it.

  Further, simply connecting the communication paths between the main devices through the IP network 200A, for example, from the telephone 2A (1) accommodated in the master main apparatus 1A to the telephone 2B (1) accommodated in the slave main apparatus 1B. ) Can't make an extension call. In other words, each main device cannot realize an extension call between the button telephone systems unless it knows the numbering plan for all main devices belonging to the same telephone system including its own device.

  In order to allow the user to make an extension call without distinguishing between each key telephone system, it is necessary to set a numbering plan in a closed number system. The closed number system is an extension number that does not overlap even part of the extension number used in each key telephone system, except for the so-called extension special number (extension special number) that can be commonly used in each key telephone system. Is a method for setting. An extension special number (extension special number) means a number for a different use from a normal extension number.

  Thus, in this embodiment, when the connection request source slave main unit does not have a number plan, the master main unit 1A assigns a number plan to the connection request source slave main unit. In this case, the master main device 1A notifies the other slave main devices of the assigned numbering plan so that the slave main devices can also register.

  In addition, when the connection request source slave main unit has a numbering plan, the master main unit 1A receives the provision of the numbering plan and determines whether or not it can be used in the telephone system. As a result of the determination, if the use is possible, the use of the numbering plan is permitted to the slave main apparatus that is the connection request source. The master main unit 1A also registers the number plan received from the connection requesting slave main unit and notifies the other slave main unit of the number plan. Enable registration.

  If the numbering plan provided by the slave device that requested the connection cannot be used because it overlaps with the numbering plan of other button telephone systems, the use of the numbering plan is prohibited and the master The main apparatus 1A assigns a new numbering plan to the slave main apparatus that is the connection request source. In this case, the master main apparatus 1A notifies the other slave main apparatus of the assigned new numbering plan so that it can be registered in the other slave main apparatuses.

  As described above, in the telephone system of this embodiment, the master main apparatus 1A functions as a management apparatus in the telephone system, and address data such as an IP address without bothering a construction worker or a user. Distribute necessary system information such as data and numbering plan data. As a result, not only an outside line call or an extension call in a key telephone system, but also a communication path can be connected between each main unit through the IP network 200A, and an extension call can be made between key telephone systems. Yes.

[Configuration example of main devices 1A, 1B, 1C, ...]
Next, in this embodiment, a configuration example of the main devices 1A, 1B, 1C,... Of each key telephone system connected through the wide area network 200 will be described. Each of the main devices 1A, 1B, 1C,... Has the same configuration and can be a master main device or a slave main device. Therefore, in the following, each of the main devices 1A, 1B, 1C,... Will be collectively referred to as the main device 1 unless otherwise indicated. Also, telephones 2A (1), 2A (2), ... connected to the main apparatus 1A, telephones 2B (1), 2B (2), ... connected to the main apparatus 1B, telephones connected to the main apparatus 1C 2C (1), 2C (2),... Are also collectively referred to as the telephone 2 unless otherwise indicated.

  FIG. 2 is a block diagram for explaining a configuration example of the main apparatus 1. As described above, the main device 1 connects a communication line through the IP network 200A and the telephone network 200B, and can control each of the telephones accommodated in its own device, which is a so-called SIP (Session Initiation Protocol). ) It functions as a server. As shown in FIG. 2, the main apparatus 1 includes a connection terminal 101 to the IP network 200 </ b> A, an IP network interface (hereinafter abbreviated as IP network I / F) 102, and a packet disassembly / generation unit 103. .

  The main apparatus 1 includes a telephone network interface (hereinafter abbreviated as a telephone network I / F) 104 and a connection terminal 105 to the telephone network 200B. The main device 1 also includes an address data storage unit 106, a number plan data storage unit 107, and a master information memory 108. Further, the main apparatus 1 includes a LAN interface (hereinafter abbreviated as LAN I / F) 109, a connection terminal 110 to the LAN, an external interface (hereinafter abbreviated as external I / F) 111, and an external terminal. 112 and a control unit 120.

  The control unit 120 controls each unit of the main apparatus 1, and although not shown, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a nonvolatile memory, and the like are connected through a system bus. It is a connected microprocessor. Further, the control unit 120 determines the connection status of the communication path, or determines whether the numbering plan such as the extension number from the slave main apparatus can be appropriately used, as will be described in detail later. It also functions as a part.

  The connection terminal 101 constitutes a connection end to the IP network 200A. The IP network I / F 102 receives a packet supplied through the IP network 200A, converts it into a packet in a format that can be processed by itself, and supplies the packet to the control unit 120. The IP network I / F 102 converts a packet to be transmitted supplied through the control unit 120 into a packet in a transmission format, and sends this to the IP network 200A.

  Connection terminal 105 constitutes a connection end to telephone network 200B. The telephone network I / F 104 receives data (information) supplied through the telephone network 200 </ b> B, converts it into data in a format that can be processed by itself, and supplies the data to the control unit 120. In addition, the telephone network I / F 104 converts data to be transmitted supplied through the control unit 120 into data in a transmission format, and transmits the data to the telephone network 200B.

  The connection terminal 110 constitutes a connection end to the LAN. The LAN I / F 109 receives a packet supplied through the LAN, converts it into a packet in a format that can be processed by the own device, and supplies the packet to the control unit 120. Also, the LAN I / F 109 converts a packet to be transmitted supplied through the control unit 120 into a packet in a transmission format, and sends this to the LAN.

  The external terminal 112 constitutes a connection end with an external device such as a PC (Personal Computer). The external I / F 111 receives data from an external device such as a PC connected to the external terminal 112, converts it into data in a format that can be processed by the own device, and supplies the data to the control unit 120. In addition, the external I / F 111 converts data to be transmitted to an external device connected to the external terminal 112 supplied through the control unit 120 into data in a format for transmission, and transmits this to the external device.

  The packet decomposition / generation unit 103 performs packet decomposition and generation. Specifically, a packet to be transmitted from the telephone set 2 connected to the main apparatus 1 through the LAN to the terminal apparatus connected to the telephone network 200B is received by the control unit 120 through the connection terminal 110 and the LAN I / F 109. . The packet is supplied from the control unit 120 to the packet decomposition / generation unit 103, where the packet is decomposed and then sent to the telephone network 200B through the control unit 120, the telephone network I / F 104, and the connection terminal 105. Sent to the other party.

  Data from the terminal device connected to the telephone network 200B to the telephone 2 connected to the main device 1 through the LAN is received by the control unit 120 through the connection terminal 105 and the telephone network I / F 104. The data is supplied from the control unit 120 to the packet disassembly / generation unit 103, where the packet is converted into a packet of a predetermined format, and then sent to the LAN through the control unit 120, the LAN I / F 109, and the connection terminal 110, and Is transmitted to the telephone 2 to be operated.

  Packets are transmitted and received between the terminal connected to the IP network 200A and the telephone set 2 connected to the main apparatus 1 through the LAN. For this reason, the packet decomposition / generation unit 103 does not perform packet decomposition or generation, and the IP network I / F 102 and the LAN I / F 109 transmit and receive the packet as it is. Similarly, packets are transmitted and received between the telephones 2 in the same button telephone system connected to the main apparatus 1 through the LAN. Therefore, also in this case, the packet decomposition / generation unit 103 does not perform packet decomposition or generation, and transmits / receives packets through the LAN I / F 109.

  The address data storage unit 106 is connected to the IP network 200A in order to realize the registrar server function, and stores and holds address data about the own device and other main devices that may be called through the own device. FIG. 3 is a diagram for explaining an example of stored data (address data) stored in the address data storage unit 106. As shown in FIG. 3, the address data storage unit 106 stores data of group ID, password, IP address, system number, system name, and priority order.

  The group ID and password are for the telephone system of this embodiment configured by connecting a plurality of main devices 1. The group ID is for enabling a plurality of telephone systems configured by connecting a plurality of main apparatuses 1 to be managed separately. The password is used for authentication as to whether or not the accessing external device is accessible to the telephone system. These group IDs and passwords are input through a PC connected through the external I / F 111 and the external terminal 112 of the main apparatus 1 and written in the corresponding area of the address data storage unit 106.

  The IP address, system number, system name, and priority data are a series of address data for the main device 1 and the main device 1 that has transmitted a connection request to the own device. The IP address is information indicating the location of the own device on the IP network 200A, and the system number and the system name are information for distinguishing each of the key telephone systems. The priority order indicates the order in which each main device becomes the master main device. The main device having the highest priority at this time is the master main device, and the other main devices are slave main devices. .

  The first registered IP address, system number, system name, and priority in the address data storage unit 106 relate to the own device. Among them, the IP address is the ISP address when the telephone server ISP server provided on the IP network 200A is first accessed through the IP network I / F 102 and the connection terminal 101 under the control of the control unit 120. It is given from the server.

  The system number, the system name, and the priority order are basically assigned to the main device belonging to the same telephone system, including the master device. For this reason, in the master main apparatus, the system number, the system name, and the priority order inputted through the PC connected through the external I / F 111 and the external terminal 112 are registered and used.

  The IP address, the system number, the system name, and the priority order registered in the second and subsequent addresses in the address data storage unit 106 relate to other main devices belonging to the same telephone system. For example, when the main apparatus 1 is a master main apparatus, when a connection request (registration request) is received from another main apparatus via the IP network I / F 102, the IP address included in the connection request is stored in the address data storage unit. 106 is registered.

  Furthermore, the control unit 120 of the master main device 1 assigns a system number, a system name, and a priority order to the main device that is the connection request source, and this is stored in the address data storage unit 106 of the main device that is the connection request source. be registered. When the main device 1 is a slave main device, the IP address, system number, system name, and priority of another main device provided from the master main device via the IP network I / F 102 are address data. Registered in the storage unit 106.

  In this way, the information registered and managed in the address data storage unit 106 is referred to, and the button telephone system of the other party requested from the telephone connected to the own machine through the LAN can be specified. To be done. Then, the main apparatus 1 can realize a function as a proxy server that transfers information (packet data) to be transmitted to the specified partner.

  The numbering plan data storage unit 107 stores numbering plan data of extension numbers assigned to each key telephone system. The numbering plan data can also be set independently in each key telephone system. However, as described above, in the telephone system of this embodiment, the numbering plan of each button telephone system adopts a closed number system in which extension numbers do not overlap even in a part of them except for extension special numbers. . For this reason, the numbering plan data is stored and managed in the master main unit by storing the numbering plan data that has already been distributed and the numbering plan data that can be distributed.

  FIG. 4 is a diagram for explaining an example of data stored in the numbering plan data storage unit 107. As shown in FIG. 4, the data stored in the numbering plan data storage unit 107 (numbering plan data) includes a system number, a numbering plan, and a distributed flag (denoted as FLG in FIG. 4). In the case of the example shown in FIG. 4, an extension number in the 1000s and a number in the 9000s are assigned as special numbers to the button telephone system with the system number “001” as a numbering plan.

  In addition, the extension number of 2000 series and the number of 9000 series are assigned as a special number to the button telephone system with the system number “002” as a numbering plan. Further, an extension number of the 3000 series is assigned as a numbering plan and a number of the 9000 series is assigned as a special number to the button telephone system having the system number “003”. In the case of the numbering plan data shown in FIG. 4, the numbering plan data for the button telephone systems with the system numbers “001” and “002” has already been distributed, and the button numbering system with the system number “003”. It is managed that the numbering plan data is not distributed.

  Note that, as shown by being surrounded by a dotted line in FIG. 2, the address data storage unit 106 and the numbering plan data storage unit 107 constitute a system information storage unit. That is, the address data stored in the address data storage unit 106 and the number plan data stored in the number plan data storage unit 107 constitute system information, and between the button telephone systems based on these system information. Communication is made possible.

  When the main device 1 is a slave main device, the master information memory 108 stores master information including an IP address and a password of the master main device. This is because the slave main apparatus accesses the master main apparatus through the IP network 200A and connects the communication path. The IP address and password of the master main device stored in the master information memory 108 are provided from a PC connected through the external I / F 111 and the external terminal 112, or a maintenance person through an operation unit (not shown) of the main device 1 It is input by.

  The registration processing unit 131, the distribution processing unit 132, and the connection state notification processing unit 133 shown in FIG. 2 are the main units for realizing the present invention. The registration processing unit 131 includes first to fourth registration units 131A, 131B, 131C, and 131D. The first and second registration units 131A and 131B function when the main device 1 is used as a master main device. The third and fourth registration units 131C and 131D function when the main device 1 is used as a slave main device.

  When the main device functions as a master main device, the first registration unit 131A receives provision of system information determined in advance, and stores this information as an address data storage unit 106 or number plan data storage as a system information storage unit. Registered in the unit 107. In this case, the predetermined system information includes address data including the IP address, system number, system name, and priority of the own device, and number plan data of the own button telephone system and other button telephone systems that are preliminarily registered. It is.

  When the main device functions as a master main device, the second registration unit 131B receives system information transmitted from the slave main device through the IP network 200A, and stores this as address data storage as a system information storage unit. Registered in the unit 106 and the number plan data storage unit 107. The system information from the slave main unit in this case is an IP address or numbering plan data as address data of the slave main unit.

  When the main device functions as a slave main device, the third registration unit 131C receives provision of system information determined in advance among the system information, and uses this as the system data storage unit 106. And registration in the number plan data storage unit 107. In this case, the predetermined system information includes an IP address as the address data of the own device, number plan data of the own button telephone system, and the like.

  When the main device functions as a slave main device, the fourth registration unit 131D transmits the system information transmitted from the master main device through the IP network 200A to the address data storage unit 106 or the number as the system information storage unit. Register in the plan data storage unit 107. In this case, the system information transmitted from the master main unit includes the IP address of the other main unit, the address data such as the system number, the system name, the priority order of the own unit and the other main unit, and the own button telephone. Information such as numbering plan data for systems and other key telephone systems.

  The distribution processing unit 132 includes first and second distribution units 132A and 132B, and functions when the main device functions as a master main device. The first distribution unit 132A registers the system information from the connection request source slave main unit in the system information storage unit by the second registration unit 131B, and then sends the telephone request to the connection request source slave main unit. Distribute system information for each of the other main devices that make up the system. The system information distributed here is address data including the IP address, system number, system name, and priority of another main apparatus, and number plan data of another button telephone system.

  After the second registration unit 132B registers the system information from the slave main device of the connection request source in the system information storage unit by the second registration unit 131B, each of the other main devices other than the connection request source. System information about the main device of the connection request source is distributed. The system information distributed here includes address data including the IP address, system number, system name, and priority of the main device of the connection request source, and number plan data of the button telephone system to which the main device of the connection request source belongs. It is.

  The connection state notification processing unit 133 functions when the main device functions as a master main device. The connection status notification processing unit 133 checks the login status (connection status) and communication status of each main device with the login (logging) from the slave main device to the master main device and logoff from the master main device (trigger). Then, this is notified to each connected slave main unit. As a result, each slave main device can appropriately determine the main device capable of communication at this time and the main device incapable of communication, and notify the user.

  In the telephone system of this embodiment configured by using the main apparatus 1 having such a configuration, it is possible to easily connect the button telephone systems using the main apparatus as a connection end to the wide area network 200. I can do it. In addition, in a telephone system configured by connecting a plurality of main devices through the wide area network 200, extension numbers are appropriately set by a closed number system so that extension calls between button telephone systems can be easily performed. Yes. In the following, a connection process between the button telephone systems performed when the telephone system of this embodiment is constructed will be specifically described.

[Communication path connection operation between button telephone systems (connection processing)]
First, the basic connection operation of the communication path between the button telephone systems will be described. Here, a case where a connection is requested from the slave main apparatus 1B installed in the branch office 1 (Tohoku) to the master main apparatus 1A installed in the head office (Tokyo) will be described. FIG. 5 is a sequence diagram for explaining an operation when a communication path is connected between the master main apparatus 1A and the slave main apparatus 1B through the IP network 200A.

  In a PC (Personal Computer) connected through the external I / F 111 and the external terminal 112 of the main apparatus 1A, predetermined system information is created in advance (step S1). Here, the system information includes group ID used in the telephone system, common data such as a password, address data such as a system number and system name and priority assigned to each button telephone system, and number plan data assigned to each button telephone system. Etc.

  When the main apparatus 1A is installed at the head office, the PC transfers the created system information to the main apparatus 1A (step S2). The first registration unit 131A of the registration processing unit 131 of the main apparatus 1A registers common data and address data in the corresponding area of the address data storage unit 106, and number plan data is registered in the corresponding area of the number plan data storage unit 107. (Step S3). That is, in step S3, an update process is performed to update common data, address data, and numbering plan data, which are predetermined system information, to the system information storage unit.

  Then, through the processing of Steps S1 to S3 described above, the address data storage unit 106 of the main device 1A has a group ID and a password, and a system number assigned to each of the main devices that constitute the telephone system, The system name and priority are registered. In addition, through the processes in steps S1 to S3 described above, the numbering plan data assigned to each button telephone system constituting the telephone system is registered in the numbering plan data storage unit 107 of the main apparatus 1A.

  In this embodiment, as shown in FIG. 3, “GP001” is registered as the group ID and “PWabc...” Is registered as the password in the address data storage unit 106. In the example shown in FIG. 3, the system numbers are “001”, “002”, “003”, the system names are “system 1”, “system 2”, “system 3”, and the priority is “first place”. ”,“ Second place ”, and“ third place ”are registered. As shown in FIG. 4, the numbering plan data storage unit 107 stores numbering plan data for the button telephone systems having system numbers “001”, “002”, and “003”.

  When the main apparatus 1A is physically connected to the IP network 200A or the telephone network 200B, the IP network I / F 102 functions in the main apparatus 1A under the control of the control unit 120, and the ISP on the telephone company side. Access the server. The main apparatus 1A receives an IP address assigned from the ISP server, and the first registration unit 131A of the registration processing unit 131 functions and registers it in the address data storage unit 106 under the control of the control unit 120 ( Step S4). In this example, it is assumed that the IP address assigned to the main apparatus 1A is “XXX.XXX.XXX.XXX”.

  Then, through the processing of step S1 to step S4, in the main apparatus 1A, address data for the own device is recorded in the address data storage unit 106. That is, in the main apparatus 1A, as shown in FIG. 3, the IP address assigned to the main apparatus 1A is “XXX.XXX.XXX.XXX”, the system number of the main apparatus 1A is “001”, and the system name Is registered as “system 1” and the priority is “first”.

  Since the priority order is “first” among the address data of the main apparatus 1A, the main apparatus 1A is selected as the master main apparatus. Further, since the system number is “001”, each of the telephones 2A (1), 2A (2),... Of the key telephone system having the master main device 1A as the connection end to the wide area network 200 has 1000 numbers. An extension number is assigned.

  On the other hand, when the main device 1B installed in the branch office 1 is physically connected to the IP network 200A or the telephone network 200B, the IP network I / F 102 functions in the main device 1B under the control of the control unit 120. Then, the ISP server on the telephone company side is accessed. Then, the main apparatus 1B receives an IP address assignment from the ISP server, and registers it in the address data storage unit 106 under the control of the control unit 120 by the third registration unit 131C of the registration processing unit 131 (see FIG. Step S5). In this example, it is assumed that the IP address assigned to the main apparatus 1B is “YYY.YYY.YYY.YY1”.

  In the process of step S5, only the address “YYY.YYY.YYY.YY1”, which is the IP address of the own device, is registered in the address data storage unit 106 of the main apparatus 1B. Therefore, since the priority order that should have been set for the master main apparatus is not set, the main apparatus 1B functions as a slave main apparatus.

  The main apparatus 1B installed in the branch office 1 is supplied with the IP address and password of the master main apparatus 1A through the PC connected through the external I / F 111 and the external terminal 112, and this is supplied to the control unit. 120 records in the master information memory 108 (step S6). As a result, “XXX.XXX.XXX.XXX” that is the IP address of the master main device 1A and “PWabc12...” That is the password are registered in the master information memory 108 of the main device 1B. As described above, in FIG. 5, the processes in steps S1 to S6 are preparation processes for connecting the communication path between the master main apparatus 1A and the slave main apparatus 1B through the IP network 200A.

  In the slave main apparatus 1B, the control unit 120 uses the IP address and password of the master main apparatus 1A in the master information memory 108 and controls the IP network I / F 102 to access the master main apparatus 1A. The connection request is transmitted (step S7). In step S7, the slave main apparatus 1B logs in to the master main apparatus 1A in order to register the button telephone system having the slave main apparatus 1B as the connection end to the network 200 in the telephone system formed in a wide area. It becomes processing.

  When the master main apparatus 1A receives a connection request from the slave main apparatus 1B, the master main apparatus 1B first authenticates whether the slave main apparatus 1B can be connected to its own device. Processing for registration in the telephone system is performed (step S8). That is, in step S8, first, the control unit 120 of the master main apparatus 1A checks whether or not the password included in the connection request is the same as the password stored in the address data storage unit 106. If so, the slave main device 1B is authenticated. If they are not the same, the slave main apparatus 1B is notified of connection refusal, and the subsequent processing is not performed.

  When authenticating the slave main device 1B, the control unit 120 of the master main device 1A controls the second registration unit 131B of the registration processing unit 131, and uses the IP address of the slave main device 1B included in the connection request as address data. Register in the storage unit 106. In this case, the second registration unit 131B searches in order from the first in the address data storage unit 106, and registers the IP address from the slave main device 1B in the IP address column of the address data where the IP address is not registered. To do.

  Through this authentication / registration process in step S8, in this example, as shown in FIG. 3, the IP address “YYY.Y” of the slave main apparatus 1B is displayed in the IP address column of the second data in the address data storage unit 106. YYY.YYY.YY1 "is registered (updated). Accordingly, the system number “002”, the system name “system 2”, and the priority “second place” are assigned to the slave main apparatus 1B.

  Next, the master main apparatus 1A distributes system information to the slave main apparatus 1B that is the connection request source (step S9). In this case, the control unit 120 of the master main device 1A controls the first distribution unit 132A of the distribution processing unit 132 to distribute system information to the slave main device 1B that is the connection request source. The system information distributed here includes common data including a group ID and a password, predetermined address data, and predetermined numbering plan data.

  The address data distributed in step S9 is the system number, system name and priority for the slave main apparatus 1B stored in the address data storage unit 106, and the IP address, system number and system name of the master main apparatus 1A. , Is priority. The numbering plan data distributed in step S9 is numbering plan data with the system number “001” and numbering plan data with the system number “002” stored in the numbering plan data storage unit 107. The numbering plan data with the system number “001” is for the master main unit 1A, and the numbering plan data with the system number “002” is for the slave main unit 1B.

  In the slave main apparatus 1B, the control unit 120 controls the fourth registration unit 131D of the registration processing unit, and records the system information provided in step S9 in the system information storage unit (step S10). That is, in step S10, the registration unit 131D registers common data and address data from the master main unit 1A in the address data storage unit 106, and number plan data from the master main unit 1A in the number plan data storage unit 107.

  In this way, the processing from step S7 to step S10 becomes the login processing from the slave main device 1B to the master main device 1A. By this series of processing, the IP network is connected between the master main device 1A and the slave main device 1B. Communication paths are connected to each other through 200A. Thus, between the telephones 2A (1), 2A (2),... LAN connected to the master main apparatus 1A and the telephones 2B (1), 2B (2),. Thus, an extension call using the extension number can be performed.

  Then, the master main apparatus 1A communicates with each other the main apparatuses that are connected to each other via the IP network 200A and their connection states (results of health check), etc., when the slave main apparatus 1B logs in. The main device connected to the road is notified (step S11). In the case of this example, only the master main device 1A and the slave main device 1B are connected to each other through the IP network 200A, so that the connection state and the like are changed from the master main device 1A to the slave main device. 1B is notified.

  Thereby, the slave main apparatus 1B can grasp the current connection status of the telephone system formed in a wide area to which the self-button telephone system belongs. Therefore, it is possible to grasp whether or not communication is possible according to the connection state without the user performing an erroneous operation such as making an extension call to the unconnected button telephone system.

  In the case of the example described with reference to FIG. 5, the numbering plan data has been described as being provided from the master main unit 1A from the beginning. However, the numbering plan data may or may not have the slave main unit from the beginning, or the slave main unit may have its own numbering plan data. In the case of the example described with reference to FIG. 5, the communication path has already been connected to the master main apparatus 1A through the IP network 200A, and no other slave main apparatus exists. For this reason, the second distribution unit 132B of the distribution processing unit 132 of the master main apparatus 1A is not used.

  Therefore, in the following, the slave main apparatus 1B is already connected to the master main apparatus 1A through the IP network 200A, and the main apparatus 1C is newly connected to the master main apparatus 1A. The operation at the time of connection will be described taking the case of requesting connection as an example. In addition, the operation at the time of connection is concretely divided into three cases: a case where the main apparatus 1C does not have a numbering plan, a case where a numbering plan is permitted, and a case where a numbering plan is prohibited. I will explain it.

[Operation (Process) when the Main Device 1C as the Connection Request Source does not have its own number plan]
FIG. 6 is a sequence diagram for explaining the operation of the telephone system when the main apparatus 1C installed in the branch office 2 is the connection request source and the main apparatus 1C has no own number plan. In FIG. 6, the main apparatus 1 </ b> B has been registered as a slave main apparatus with respect to the master main apparatus 1 </ b> A by the series of processes described with reference to FIG. It is assumed that a communication path is connected to 1A through the IP network 200A.

  When the main apparatus 1C to be newly connected to the telephone system is physically connected to the IP network 200A or the telephone network 200B, the IP network I / F 102 functions under the control of the control unit 120, and the telephone company side Access to the ISP server. Then, the main apparatus 1C receives an IP address assignment from the ISP server, and under the control of the control unit 120, the third registration unit 131C of the registration processing unit 131 functions and registers it in the address data storage unit 106 ( Step S21). In this example, it is assumed that the IP address assigned to the main apparatus 1C is “YYY.YYY.YYY.YY2”.

  In the process of step S21, the address data storage unit 106 of the main apparatus 1C is in a state where only its own IP address, for example, “YYY.YYY.YYY.YY2” is registered. Accordingly, since priority is not set for the main apparatus 1C in this state, it functions as a slave main apparatus.

  Then, the main device 1C installed in the branch office 2 is supplied with the IP address and password of the master main device 1A through the PC connected through the external I / F 111 and the external terminal 112, and this is supplied to the control unit. 120 records in the master information memory 108 (step S22). As a result, “XXX.XXX.XXX.XXX” that is the IP address of the master main device 1A and “PWabc12...” That is the password are registered in the master information memory 108 of the main device 1C.

  Thereafter, in the slave main apparatus 1C, the control unit 120 uses the IP address and password of the master main apparatus 1A in the master information memory 108 and controls the IP network I / F 102 to access the master main apparatus 1A. Then, a connection request is transmitted (step S23). In step S23, the slave main apparatus 1C logs in to the master main apparatus 1A in order to register the button telephone system having the slave main apparatus 1C as a connection end to the network 200 in a telephone system formed in a wide area. It becomes processing. Then, in the slave main apparatus 1C, the control unit 120 controls the IP network I / F 102 to notify the master main apparatus 1A that the own apparatus does not have a numbering plan (step S24).

  In the master main apparatus 1A, the control unit 120 first performs authentication based on the password from the slave main apparatus 1C. If the authentication is obtained, the IP address included in the connection request from the slave main apparatus 1C is converted into the address data storage unit. 106 (step S25). In step S25, the IP address of the slave main apparatus 1C is searched in order from the first in the address data storage unit 106, and is registered in the IP address column of data for which no IP address is registered.

  In the case of this example, as shown in FIG. 3, since the IP address field of the third data in the address data storage unit 106 is blank, the IP address “YYY.YYY.YYY. YY2 "is registered. Thus, the system number “003”, the system name “system 3”, and the priority “third place” are assigned to the slave main apparatus 1C. Then, the control unit 120 of the master main apparatus 1A forms an “OK” notification indicating that a notification indicating that there is no numbering plan has been received, and sends it back to the slave main apparatus 1C via the IP network I / F 102 (step). S26).

  Thereafter, in the master main device 1A, the first distribution unit 132A of the distribution processing unit 132 functions under the control of the control unit 120, and distributes system information to the slave main device 1C that is the connection request source (step S27). ). In this case, the system information includes common data including a group ID and a password, address data, and numbering plan data. The address data includes the system number, system name, and priority of the slave main apparatus 1C, and the IP addresses, system numbers, system names, and priorities of the master main apparatus 1A and slave main apparatus 1B that already configure the telephone system. It is. The numbering plan data is numbering plan data for each of the master main unit 1A, the slave main unit 1B, and the slave main unit 1C. More specifically, the numbering plan data with the system number “001”, the numbering plan data with the system number “002”, and the numbering plan data with the system number “003” are sent to the slave main unit 1C. Distributed.

  Then, in the slave main device 1C as the connection request source, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120, and registers the system information from the master main device 1A in the system information storage. (Step S28). In this case, of the system information, common data and address data are registered in the address data storage unit 106, and number plan data is registered in the number plan data storage unit 107, respectively.

  In addition, the master main device 1A is connected to all slave main devices that already constitute the telephone system other than the connection request source (in this case, to the slave main device 1B). System information about the main apparatus 1C is distributed (step S29). In step S29, the master main apparatus 1A operates under the control of the control unit 120, the second distribution unit 132B of the distribution processing unit 132 functions, and the slave main apparatus 1C that is the address data registered in the address data storage unit 106. The IP address, system number, system name, and priority are distributed to the slave main apparatus 1B. In addition, the master main device 1A functions as the second distribution unit 132B of the distribution processing unit 132 under the control of the control unit 120, and the number plan for the slave main device 1C registered in the number plan data storage unit 107. That is, the numbering plan with the system number “003” is distributed to the slave main apparatus 1B.

  In the slave main device 1B that is already one of the components of the telephone system, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120, and the slave main device 1C System information is registered in the system information storage unit (step S30). As a result, the address data is registered in the address data storage unit 106 and the number plan data is registered in the number plan data storage unit 107 (step S30).

  In this way, the system information of the master main device 1A and slave main devices 1B and 1C constituting the telephone system is registered in the master main device 1A and slave main devices 1B and 1C, respectively, and the connection environment is prepared. Although not shown in FIG. 6, for example, the slave main device 1C and the slave main device 1C are accessed by using the IP address and password of the slave main device 1B from the slave main device 1C. A communication path is also connected to 1B through the IP network 200A. As a result, the main apparatuses 1A, 1B, and 1C are connected to each other through the IP network 200A and can perform extension calls with each other.

[Operation when the use of the numbering plan in the main device 1C of the connection request source is permitted (processing)]
FIG. 7 shows the case of the telephone system in the case where the main device 1C installed in the branch office 2 becomes the connection request source, and the number plan data exists in the main device 1C and the use of the number plan data is permitted. It is a sequence diagram for demonstrating operation | movement. In the sequence diagram shown in FIG. 7 as well, as shown by being surrounded by a double line, the main apparatus 1B has been registered as a slave main apparatus with respect to the master main apparatus 1A by the series of processes described with reference to FIG. It is assumed that a communication path is connected to the master main apparatus 1A through the IP network 200A.

  In FIG. 7, the processing from step S31 to step S33 is performed in the same manner as the processing from step S21 to step S23 shown in FIG. That is, in the process of step S31, the slave main apparatus 1C acquires, for example, “YYY.YYY.YYY.YY2”, which is the IP address for its own device, and the third registration unit 131C of the registration processing unit 131 acquires this. Functions and registers in the address data storage unit 106. In the process of step S32, the control unit 120 registers “XXX.XXX.XXX.XXX” that is the IP address of the master main device 1A and “PWabc12...” That is the password in the master information memory 108 of the main device 1C. To do. In step S33, the slave main apparatus 1C logs in to the master main apparatus 1A using the registration information in the master information memory 108.

  The slave main unit 1C in this example holds numbering plan data (own numbering plan data). Therefore, the control unit 120 of the slave main apparatus 1C reads out its own number plan data from the number plan data storage unit 107 and notifies the master main apparatus 1A through the IP network I / F 102 (step S34). In this example, the numbering plan data notified from the slave main unit 1C to the master main unit 1A uses the 3000 series as the extension number and the 9000 series as the special number as shown in FIG. .

  In the master main apparatus 1A, the control unit 120 performs authentication based on the password. If the authentication is successful, the IP address included in the connection request from the slave main apparatus 1C is registered in the address data storage unit 106 and further provided. It is determined whether the numbering plan data thus obtained is available (step S35). In this way, the control unit 120 executes a series of processes of the authentication process, the registration process, and the determination process in the process of step S35.

  In the IP address registration process in step S35, as described with reference to FIG. 3, the IP address column of the third data from the top of the address data storage unit 106 is registered, and the slave main apparatus 1C includes the system A number “003”, a system name “system 3”, and a priority “third” are assigned. Further, in the discrimination processing in step S35, the number plan data provided from the slave main unit 1C is matched with each number plan data registered in the number plan data storage unit 107, and provided from the slave main unit 1C. It is determined whether the numbering plan data is available.

  Note that the determination as to whether the numbering plan data provided from the slave main apparatus 1C is available in step S35 is performed from several viewpoints. First, when the number plan data that matches the transmitted number plan data does not exist in the number plan data storage unit 107, it is determined that the transmitted number plan data can be used. In this case, since the numbering plan data of the master main unit 1A does not exist in the numbering plan data storage unit 107, the control unit 120 controls the second registration unit 132B of the registration processing unit 131 to control the slave main unit. The number plan data from 1C is also registered in the number plan data storage unit 107 as number plan data from the slave main unit 1C (number plan data with the system number “003”).

  When the number plan data that matches the transmitted number plan data exists in the number plan data storage unit 107, the number plan data in the number plan data storage unit 107 is the source of the number plan data ( In the case of this example, it is determined whether or not it is assigned to the slave main unit 1C). Here, when it is determined that the number plan data in the number plan data storage unit 107 is assigned to the number plan data transmission source, the transmitted number plan data can be used. Determine.

  In other cases, that is, number plan data that matches the transmitted number plan data exists in the number plan data storage unit 107, and the number plan data in the number plan data storage unit 107 is number plan data. When it is determined that the number is not assigned to the transmission source, it is determined that the number plan data transmitted cannot be used.

  Assume that it is determined in the determination process performed in step S35 that the numbering plan data transmitted from the slave main apparatus 1C can be used as it is as the numbering plan data of the slave main apparatus 1C. In this case, the control unit 120 of the master main apparatus 1A forms a message indicating permission to use the numbering plan data and transmits it to the slave main apparatus 1C as the transmission source (step S36).

  Thereafter, in the master main apparatus 1A, the first distribution unit 132A of the distribution processing unit 132 functions under the control of the control unit 120, and system information including common data, address data, and numbering plan data is transmitted to the connection request source. Distributed to the slave main unit 1C (step S37). In this case, the address data includes the system number, system name, and priority of the slave main apparatus 1C, and the IP addresses, system numbers, system names, and priorities of the master main apparatus 1A and slave main apparatus 1B that already configure the telephone system. It is rank. The numbering plan data in this case is the numbering plan data of each of the master main device 1A and the slave main device 1B. The numbering plan data for the slave main unit 1C can be used as it is as it is already held by the slave main unit 1C, so that the numbering plan for the slave main unit 1C is not provided.

  Then, in the slave main apparatus 1C as the connection request source, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120, and the common data and address data are stored in the address data storage unit 106 in the number plan. The data is registered in the numbering plan data storage unit 107 (step S38). Since the number plan data for the own device is not provided from the master main unit 1A, the number plan data stored in the number plan data storage unit 107 is continuously used.

  In addition, the master main apparatus 1A is connected to the slave main apparatus that already configures the telephone system other than the connection request source, and in this case, to the slave main apparatus 1B, the slave main apparatus 1C that is the connection request source. System information about is distributed (step S39). Specifically, the master main device 1A is the address data for the slave main device 1C registered in the address data storage unit 106, under the control of the control unit 120, in which the second distribution unit 132B of the distribution processing unit 132 functions. A certain IP address, system number, system name, and priority are distributed to the slave main apparatus 1B. In addition, the master main device 1A functions as the second distribution unit 132B of the distribution processing unit 132 under the control of the control unit 120, and the number plan for the slave main device 1C registered in the number plan data storage unit 107. That is, the numbering plan with the system number “003” is distributed to the slave main apparatus 1B.

  In the existing slave main device 1B, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120. Address data for the slave main device 1C is stored in the address data storage unit 106 as a number. The plan data is registered in the number plan data storage unit 107 (step S40).

  Thereby, the common data and the numbering plan of the master main apparatus 1A and slave main apparatuses 1B and 1C constituting the telephone system are registered in the master main apparatus 1A and slave main apparatuses 1B and 1C, respectively, and the connection environment is prepared. Although not shown in FIG. 7, for example, the slave main apparatus 1C and the slave main apparatus are accessed by accessing the slave main apparatus 1B using the IP address and password of the slave main apparatus 1B. A communication path is also connected to 1B through the IP network 200A. As a result, the main apparatuses 1A, 1B, and 1C are connected to each other through the IP network 200A and can perform extension calls with each other.

[Operation (Processing) when Use of Own Number Plan in Main Device 1C of Connection Request Source is Prohibited]
FIG. 8 shows a case of the telephone system in the case where the main device 1C installed in the branch office 2 is the connection request source, and the number plan data exists in the main device 1C and the use of the number plan data is prohibited. It is a sequence diagram for demonstrating operation | movement. In the sequence diagram shown in FIG. 8 as well, the main apparatus 1B has been registered as a slave main apparatus with respect to the master main apparatus 1A by the series of processes described with reference to FIG. It is assumed that a communication path is connected to the master main apparatus 1A through the IP network 200A.

  In FIG. 8, the processing from step S41 to step S43 is performed in the same manner as the processing from step S21 to step S23 shown in FIG. That is, in the process of step S41, the slave main apparatus 1C acquires, for example, “YYY.YYY.YYY.YY2”, which is the IP address for its own device, and the third registration unit 131C of the registration processing unit 131 acquires this. Functions and registers in the address data storage unit 106. In the process of step S42, the control unit 120 registers “XXX.XXX.XXX.XXX” that is the IP address of the master main device 1A and “PWabc12...” That is the password in the master information memory 108 of the main device 1C. To do. In the process of step S43, the slave main apparatus 1C logs in to the master main apparatus 1A using the registration information in the master information memory 108.

  The slave main unit 1C in this example holds numbering plan data (own numbering plan data). For this reason, the control unit 120 of the slave main apparatus 1C reads out its own number plan data from the number plan data storage unit 107, and notifies the master main apparatus 1A through the IP network I / F 102 (step S44). In this example, the numbering plan data notified from the slave main apparatus 1C to the master main apparatus 1A uses the 2000 series as the extension number and the 9000 series as the special number as shown in FIG. . That is, the self-number plan data held by the slave main apparatus 1C is already assigned to the slave main apparatus 1B having the system number “002” as described with reference to FIG.

  In the master main apparatus 1A, each process of authentication, registration, and determination is performed (step S45) in the same manner as the process of step S35 shown in FIG. That is, the control unit 120 of the master main apparatus 1A first performs authentication based on the password. Here, if the authentication is obtained, the IP address included in the connection request from the slave main apparatus 1C is registered in the address data storage unit 106. In this registration, as described with reference to FIG. 3, it is registered in the IP address column of the third data from the top of the address data storage unit 106, and the slave main apparatus 1 C has a system number “003”, a system name “ System 3 ”and priority“ third ”are assigned.

  Further, the control unit 120 matches the number plan data provided from the slave main unit 1C with each number plan data registered in the number plan data storage unit 107, and the number provided from the slave main unit 1C. Determine whether plan data is available. As described above, in this example, the numbering plan from the slave main apparatus 1C cannot be used because the 2000 series is already used as the extension number assigned to the slave main apparatus 1B.

  For this reason, it is determined in the determination process in step S45 that the number plan data transmitted from the slave main apparatus 1C cannot be used as it is as the number plan data of the slave main apparatus 1C. In this case, the control unit 120 of the master main apparatus 1A forms a message indicating the prohibition of use of the numbering plan data and transmits it to the transmission source slave main apparatus 1C (step S46).

  Thereafter, in the master main device 1A, the first distribution unit 132A of the distribution processing unit 132 functions under the control of the control unit 120, and distributes system information to the slave main device 1C that is the connection request source (step S47). ). In this step S47, system information consisting of common data consisting of group ID and password, address data and numbering plan data is distributed from the master main unit 1A to the slave main unit 1C. In this case, the address data includes the system number, system name, and priority of the slave main apparatus 1C, and the IP addresses, system numbers, system names, and priorities of the master main apparatus 1A and slave main apparatus 1B that already configure the telephone system. It is rank.

  The numbering plan data in this case is the numbering plan data of the master main device 1A, the slave main device 1B, and the slave main device 1C. The number plan data of the slave main device 1C cannot be used as it is already held by the slave main device 1C. Therefore, the master main unit 1A sends the number plan data having the system number “003”, which is the number plan data for the slave main unit 1C in the number plan data storage unit 107, to the slave main unit 1C and the number for the slave main unit 1C. Provide as planning data.

  Then, in the slave main device 1C as the connection request source, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120, and the common data and the address data are stored in the address data storage unit 106. The numbering plan data is registered in the numbering plan data storage unit 107 (step S48).

  In this case, the numbering plan data of the master main unit 1A and the slave main unit 1B is additionally recorded in the numbering plan data storage unit 107 of the slave main unit 1C. Then, the self-number plan data (number plan data with extension numbers in the 2000s and special numbers in the 9000s) held by the slave main unit 1C is discarded, and the system number provided by the master main unit 1A is “003”. Overwrite the numbering plan data. As a result, in the slave main apparatus 1C, the numbering plan data distributed from the master main apparatus 1A in the 3000 series and the special number in the 9000 series is used as the own number planning data.

  In addition, the master main apparatus 1A is connected to the slave main apparatus that already configures the telephone system other than the connection request source, and in this case, to the slave main apparatus 1B, the slave main apparatus 1C that is the connection request source. System information about is distributed (step S49). Specifically, the master main device 1A is the address data for the slave main device 1C registered in the address data storage unit 106, under the control of the control unit 120, in which the second distribution unit 132B of the distribution processing unit 132 functions. A certain IP address, system number, system name, and priority are distributed to the slave main apparatus 1B. In addition, the master main device 1A functions as the second distribution unit 132B of the distribution processing unit 132 under the control of the control unit 120, and the number plan for the slave main device 1C registered in the number plan data storage unit 107. Data, that is, numbering plan data with the system number “003” is distributed to the slave main apparatus 1B.

  In the existing slave main device 1B, the fourth registration unit 131D of the registration processing unit 131 functions under the control of the control unit 120. Address data for the slave main device 1C is stored in the address data storage unit 106 as a number. The plan data is registered in the number plan data storage unit 107 (step S50).

  As a result, the system information of the master main device 1A and slave main devices 1B and 1C constituting the telephone system is registered in the master main device 1A and slave main devices 1B and 1C, respectively, and the connection environment is prepared. Although not shown in FIG. 8, for example, the slave main device 1C accesses the slave main device 1B using the IP address and password of the slave main device 1B, so that the slave main device 1C and the slave main device are connected. A communication path is also connected to 1B through the IP network 200A. As a result, the main apparatuses 1A, 1B, and 1C are connected to each other through the IP network 200A and can perform extension calls with each other.

  As described with reference to FIGS. 5 to 8, in the telephone system of this embodiment, one main device is a master main device, and the other main devices are slave main devices. Then, by accessing the master main unit from the slave main unit and sending a connection request, system information necessary for the master main unit to form the telephone system is transferred to the slave main unit that has made the connection request and the telephone system already Distribute to the configured slave main unit. As a result, the construction manager and other personnel do not need to set detailed system information for each main unit, but the master main unit provides information necessary for configuring the telephone system to each slave main unit. Since it is distributed, the telephone system can be configured almost automatically.

[Extension phone processing]
In the telephone system of this embodiment configured as described above, an operation (process) when an extension telephone is placed from a telephone of one button telephone system to a telephone of another button telephone system will be described. FIG. 9 is a sequence for explaining the operation (processing) when placing an extension call from the telephone 2A (1) connected to the master main apparatus 1A via the LAN to the telephone 2B (1) connected via LAN to the slave main apparatus 1B. FIG.

  In the address data storage unit 106 of the master main apparatus 1A, as shown in FIG. 3, common data (group ID, password) and address data (IP address, system) of each main apparatus constituting the telephone system of this embodiment are stored. Number, system name, priority). Further, as shown in FIG. 4, the numbering plan data of each main unit constituting the telephone system of this embodiment is registered in the numbering plan data storage unit 107 of the master main unit 1A.

  The common data and the address data stored in the address data storage unit 106 of the master main apparatus 1A are also registered in the address data storage units 106 of the slave main apparatuses 1B and 1C. However, the address data registration order is such that its own address data is located at the top. Also, the same numbering plan data as the numbering plan data storage unit 107 of the master main unit 1A is registered in the numbering plan data storage unit 107 of the slave main units 1B and 1C.

  In this case, it is assumed that “2000” is dialed in the telephone 2A (1) with the extension number 1000 connected to the master main apparatus 1A by LAN, and an extension call is made to the telephone with the extension number 2000. To do. In this case, the calling telephone 2A (1) forms a calling message for the extension 2000 and transmits it to the main device 1A of the own key telephone system through the LAN (step S51). The main apparatus 1A that has received the calling message identifies which key telephone system telephone the extension number 2000 has (step S52).

  In step S52, the control unit 120 of the main apparatus 1A refers to each number plan data in the number plan data storage unit 107, and identifies the system number of the key telephone system to which the extension number 2000 is connected. Then, the main apparatus 1A of the caller makes a call with the caller as the telephone with the extension number 1000 of the system number “001” and the callee as the telephone with the extension number 2000 of the system number “002”. A request is formed and transmitted to the main apparatus 1B through the communication path connected through the IP network 200A (step S53).

  When receiving a call request from the main apparatus 1B, the control unit 120 of the main apparatus 1B that receives the call forms a call message for calling the telephone with the extension number 2000 and transmits it to the telephone with the extension number 2000 through the LAN. (Step S54). In the telephone 2B (1) having the extension number of 2000 that has received the call message, in response to the call message, an indication that an incoming call from the extension number of 1000 has occurred is displayed on the display unit, and a ring tone is also sent. It is made to ring (step S55).

  Thereafter, when a response operation (off-hook operation) is performed on the telephone 2B (1) having the extension number 2000, the telephone 2B (1) forms a response notification message for the telephone having the extension number 1000, and through the LAN. It transmits to the main apparatus 1B (step S56). The control unit 120 of the main apparatus 1B transmits the response notification message to the main apparatus 1A through the communication path connected through the IP network 200A (step S57).

  The main device 1A notifies the response notification message from the main device 1B to the caller telephone set 2A (1) through the LAN (step S58). As a result, a telephone line is connected through the LAN and IP network 200A between the caller telephone 2A (1) and the callee telephone 2B (1) so that a telephone call can be made (step). S59).

  Thereafter, for example, when a telephone call end operation (on-hook operation) is performed on the telephone 2A (1) having the extension number 1000, the telephone 2A (1) forms a disconnection notification message for the telephone having the extension number 2000. Then, the data is transmitted to the main apparatus 1A through the LAN (step S60). The control unit 120 of the main apparatus 1A transmits the disconnection notification message to the main apparatus 1B to which the communication path is connected through the IP network 200A (step S61).

  The main apparatus 1B notifies the disconnection notification message from the main apparatus 1A to the destination telephone 2B (1) through the LAN (step S62). Thereafter, the main apparatus 1B forms a call line release notification message and transmits it to the main apparatus 1A (step S63). The main apparatus 1A transmits the release notification message to the caller telephone 2A (2) through the LAN (step S64). As a result, the telephone line connected between the caller telephone 2A (1) and the callee telephone 2B (1) is released.

  As described above, in the telephone system of this embodiment, the numbering scheme of the closed number system is appropriately distributed to each slave main apparatus by the master main apparatus 1A. It is possible to make an extension call by simply inputting an extension number to a telephone of another button telephone system.

[Effect of the embodiment]
According to the telephone system of this embodiment, system information about the master main apparatus and each slave main apparatus constituting the telephone system can be provided and registered to each slave main apparatus with the master main apparatus 1A as the center. I am doing so. As a result, system information consisting of common data, address data, numbering plan data, etc., can be almost automatically registered for each slave main unit without manual registration directly by construction personnel or telephone system users. Register and configure your phone system easily and properly.

  In other words, address data required by each button telephone system and system information such as closed number number plan data are appropriately applied to each of a plurality of button telephone system main apparatuses connected through the IP network 200A. And can easily connect to the key telephone system through the IP network 200A.

[Variations]
In the above-described embodiment, the main apparatus 1A is the master main apparatus and the main apparatuses 1B and 1C are slave main apparatuses. However, the present invention is not limited to this. The main devices 1B and 1C also have a function of becoming a master main device. Further, the number of main devices constituting the telephone system is not particularly limited. In addition, when the master main unit and slave main unit are fixedly defined, the main unit that is the master main unit is equipped with only the function as the master main unit, and the main unit that is the slave main unit It is also possible to configure so that only the function as the slave main device is mounted. In the case of providing a function only as a master main apparatus, the first and second registration units 131A and 131B of the registration processing unit 131 and the distribution processing unit 132 may be provided. In addition, when a function only as a slave main device is provided, the third and fourth registration units 131C and 131D of the registration processing unit 131 may be provided.

  In the above-described embodiment, the system information set in advance for the master main apparatus 1A has been described as being registered through the PC connected through the external I / F 111 and the external terminal 112. However, the present invention is not limited to this. is not. For example, system information may be prepared in a predetermined server device provided on the IP network 200A, and the master main device 1A may access the server device to download predetermined system information. Similarly, information related to the master main device such as the IP address and password of the master main device registered in each slave main device is also prepared in a predetermined server device on the IP network 200A. Then, each slave main device may access the server device and download information on the prepared master main device. In this case, software for downloading data may be installed in the master main device or the slave main device, and this may be executed as necessary.

  In the embodiment described above, the telephone system is described as comprising the main device 1A of the head office (Tokyo), the main device 1B of the branch office 1 (Tohoku), and the main device 1C of the branch office 2 (Kansai). . However, it is not limited to this. For example, each of the Kanto region, the Tohoku region, and the Kansai region has a plurality of branches, and main devices are installed in these branches, and the main devices installed in the branches also connect communication paths through the IP network 200A. To build a telephone system.

  In this case, the group ID included in the common data is also used. That is, a group ID indicating the Kanto region is assigned to a main apparatus located in the head office, branch office, or branch located in the Kanto region. In addition, a group ID indicating the Tohoku region is assigned to a main apparatus located in the head office, branch office, or branch located in the Tohoku region. In addition, a group ID indicating the Kansai region is assigned to the main apparatus located in the head office, branch office, or branch located in the Kansai region.

  In this way, in the telephone system, when making an extension call between the button telephone systems, the group ID of the group to which the destination telephone belongs and the button telephone system based on the inputted extension number of the destination. Specify the system number. As a result, it is possible to appropriately grasp which group of which key telephone system the incoming callee belongs to, and to control to quickly connect the communication path. In this case, the address data storage unit 106 may store address data for each group ID.

  In the above-described embodiment, the priority order for becoming the master main device is set. For this reason, in the case of the above-described embodiment, when the main apparatus 1A installed in the head office becomes unmovable for some reason, the main apparatus 1B having the “second rank” wired order is the master. By becoming the main device, it is possible to avoid the disadvantage that the newly installed main device is not added to the telephone system.

  In the above-described embodiment, the case where the main apparatus is connected through the IP network 200A to construct a wide-area telephone system has been described as an example. However, for example, through a network other than the IP network 200A such as a dedicated line. The present invention can also be applied to a case where a telephone system is constructed by connecting main apparatuses. In this case, the address data includes identification information that can identify the main device such as a representative telephone number.
