Description

  The present invention relates to a network management server and a network management method having an automatic initial setting function, and in particular, a network management server capable of downloading an initial setting value for initial setting to a network terminal connected to the network, and The present invention relates to a network management method.

  With the recent development of information communication technology, a system that connects a terminal device such as a computer to a LAN, globally communicates with a terminal device or server device connected to another LAN via the Internet, and performs various information processing. Widely used. For example, not only information communication between computers but also making a computer function as an IP telephone is one of them.

  In a network system connected to a network terminal such as an IP phone, when the power of the network terminal is turned on, its own MAC (Media Access Control) address is sent as an identification ID to the network management server, and the initial network terminal There is known a network management system that makes a setting request and downloads an initial value for initial setting from a network management server to a network terminal that has requested the initial setting.

  In such a form of network management system, if the MAC address of the network terminal and the initial setting values of the network terminal (IP addresses of various servers, telephone numbers, other communication setting initial values) are registered in the network management server The network terminal can obtain the initial setting value of the network terminal from the network management server, perform its own initial setting, and perform normal operation, for example, operation as a telephone.

  The MAC address is used to identify the network terminal connected to the network, and is also called "Ethernet (registered trademark) address", "physical address", "hardware address", etc. Yes. The MAC address is a number assigned to each Ethernet (registered trademark) interface. When one network terminal has a plurality of Ethernet (registered trademark) interfaces, a different MAC address is assigned to each interface. . In general, a 48-bit address is used, and each octet is represented by a hexadecimal number separated by a colon or a hyphen. This MAC address is a “physical address”, and is a unique address assigned to each hardware, unlike an IP address that can be changed by software.

  Several methods have been proposed for initial setting of a network terminal. For example, in the following Patent Document 1 (Japanese Patent Laid-Open No. 2003-23424), communication parameters of a network device (network terminal) are relatively set. A setting method and a system for performing an initial setting easily while maintaining security are disclosed.

The system disclosed in Patent Literature 1 is a network system including a management target device connected to a network and a management device that manages the management target device, and the management device is configured to store the management target device as the management target device. A first IC card drive that stores communication parameters that enable communication on the network and enables management of the device to be managed by the management device in an IC card; A network system including a second IC card drive that reads the stored communication parameter and a management target device that sets the read communication parameter.
Japanese Unexamined Patent Publication No. 2003-23424 (FIG. 1)

  However, the network system disclosed in Patent Document 1 initializes communication parameters of a network terminal, and sends its own MAC (Media Access Control) address as an identification ID of the network terminal to the network management server. It cannot be applied to a network management system that makes an initial setting request for a network terminal and downloads an initial value for initial setting from the network management server to the requested network terminal.

  This is because, in order to download the initial value for initial setting from the network management server to the network terminal, communication parameters are set in the network terminal by a DHCP (Dynamic Host Configuration Protocol) server or the like. Although it is necessary that the network terminal is connected to the LAN and can communicate between the network management server and the network terminal, the system disclosed in Patent Document 1 sets communication parameters. This is because the network terminal is not connected to the LAN and cannot communicate.

  In order for network terminals to download their own initial settings from the network management server, even if the initial settings such as communication parameters have been completed on the network terminal and communication with the network management server is possible, the network management It is necessary that the MAC address of the network terminal is registered in the server, and an initial value for initial setting is registered for each network terminal. For this registration, the network administrator individually performs a registration operation using a GUI (Graphical User Interface, usually connected to the network management server using a web browser, etc.) provided in the network management server. be able to.

  However, this method is a convenient and convenient method for registering a small number of network terminals. However, in the case of an IP phone with a large number of network terminals or the initial setting to be set for each type of network terminal When there are many items and each setting value is different, the task of registering the MAC address of each network terminal and the setting value for each initial setting in the network management server becomes enormous. There is a problem that the burden on the person increases and it becomes extremely difficult.

  As a result of various studies to solve the above problems, the inventor of the present application reads a template file defining initial setting items and attributes for each model of the network terminal into the network management server, The present invention has been completed by paying attention to the fact that it is possible to easily create a management database for each model of network terminal by creating a management database having initial setting items as data items.

  In addition, when the management database is composed of a registered terminal database and an unregistered terminal database, and an initial setting request is received from a network terminal that is not registered in the registered terminal database, the MAC address included in the initial setting request is changed to the model name. No registration is made in the unregistered terminal database corresponding to the above, the unregistered terminal database is created and exported as a file in a data format that can be exported and imported, and a setting value for initial setting is set by a personal computer (PC). The present invention has been completed by finding that the initial setting values can be easily registered by importing the written and written file in the data format into the network management server and registering it in the registered terminal database. .

  That is, the present invention aims to solve the above problems, and provides a network management server and a network management method capable of easily registering the MAC address of each network terminal and each initial setting value. For the purpose.

  The present invention is to solve such problems, and a network management server having an automatic initial setting function according to claim 1 is composed of a network management server connected to a network and a plurality of network terminals.

And a file output processing unit that creates and exports the data as a file having a different data format.

  A network management method having an automatic initial setting function according to claim 3 comprises a network management server connected to a network and a plurality of network terminals, wherein the network management server is an initial for initial setting of each network terminal. A management database for storing setting values is provided. Based on an initial setting request including a MAC address and a model name transmitted from a network terminal, an initial setting value of the network terminal corresponding to the MAC address is read from the management database and A network management method for transmitting to a network terminal, wherein the management database includes, for each model of the network terminal, a registered terminal database and an unregistered terminal database having a MAC address and the initial setting item as data items, Registration end When receiving an initial setting request from a network terminal not registered in the database, it includes a process of registering in an unregistered terminal database of the corresponding model based on the MAC address and model name included in the initial setting request. .

  A network management method having an automatic initial setting function according to claim 4 is a network management method having an automatic initial setting function according to claim 3, wherein the network management method further exports the unregistered terminal database. And a process of creating and exporting the file as an importable data format file, and a process of importing the data format file in which the setting value for initial setting is written and registering it in the registration terminal database. It is characterized by.

  In the invention according to claim 1, when an initial setting request is received from a network terminal that is not registered in the registered terminal database, the MAC address included in the initial setting request is registered in the unregistered terminal database corresponding to the model name. An initial setting request processing unit is provided. According to such a configuration, the MAC address of the network terminal that is not registered in the management database can be registered in the unregistered database of the corresponding model very easily, and the work of the network administrator can be reduced.

  In the invention according to claim 2, the network management server has a file output processing unit for creating and exporting an unregistered terminal database as a file in a data format that can be exported and imported. According to such a configuration, the contents of the unregistered terminal database can be easily exported to a PC or the like and used.

  In the invention according to claim 3, the management database has a registered terminal database and an unregistered terminal database in which the MAC address and the initial setting item are data items for each model of the network terminal, and is registered in the registered terminal database. In the case where an initial setting request is received from a network terminal that does not exist, a process of registering in the unregistered terminal database of the corresponding model based on the MAC address and model name included in the initial setting request is included. With this configuration, when an initial setting request is received from an unregistered terminal, the network management server reads the MAC address and model name of the unregistered terminal, and automatically reads the read MAC address in the unregistered terminal database of the model name. Since registration is possible, it is not necessary to input a MAC address using a keyboard or the like, and the work of the network administrator can be reduced.

The burden can be greatly reduced.

  As described above, according to the network management server and the network management method of the present invention, the network management server creates and adds a registered terminal database and an unregistered terminal database for each model by reading the template file for each model. Therefore, the management database can be easily created, and even if the number of terminals increases, it is possible to cope with the creation of the template file alone.

  In addition, when the network management server receives an initial setting request from an unregistered terminal, it can read the MAC address and model name of the unregistered terminal, and can automatically register the read MAC address in the unregistered terminal database of the model name. This eliminates the need to input the MAC address using a network, etc., and reduces the work of the network administrator.

  In addition, the unregistered terminal database can be exported and imported as a CSV file, for example, and can be input / output to / from the personal computer. There is an effect that the set value can be input and the efficiency of registration of the terminal can be increased.

  Furthermore, according to the network management method of the present invention, it is possible to efficiently create a management database for managing the initial setting values of a huge number of network terminals and register the initial setting values in the management database. It is possible to greatly reduce the work burden on the network administrator.

  Hereinafter, a network management server and a network management method according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing a configuration of a network system to which a network management method according to the present invention is applied. This network system includes a plurality of network terminals 2 to 5 connected to a LAN (Local Area Network), and a network management server 1 for automatically performing initial settings of these network terminals 2 to 5. Yes. Further, a personal computer (PC) 6 used by a network administrator and various servers 7 such as a file server and a WEB server are connected to the LAN.

  In the following description, the case where the network terminals 2 to 5 are IP telephones will be described as a specific example, but it goes without saying that the network terminals may be network terminals other than IP telephones.

  The IP phones of the network terminals 2 to 4 have the model A, and the MAC addresses are assigned MAC1, MAC2, and MAC3, respectively. The IP phone of the network terminal 5 has the model B and the MAC address is assigned MAC4. The initial setting of the communication parameters has been completed, and communication with the network management server 1 is possible.

  In order for the network terminals 2 to 5 to function as IP telephones, initial setting is required. The initial setting items include, for example, a telephone number, a user ID for logging in to the network management server 1, a password, a display name to be displayed at the destination, an outside line, an extension ringtone, a ringtone, and the like. If the phone model is different, it is necessary to set an initial value for each function of the corresponding model.

  As described above, this initial setting value is registered in the network management server 1, and when the network terminals 2 to 5 are powered on, the network terminal 2-5 logs in to the network management server 1 and downloads the initial setting value. Thus, the initial settings of the network terminals 2 to 5 are automatically performed. The initial setting request transmitted from the network terminals 2 to 5 to the network management server 1 includes a MAC address, and the network management server 1 transmits the initial setting value of the corresponding network terminal using the MAC address as an identification ID.

  In order to perform such an automatic initial setting function, it is necessary to register the initial setting value in the network management server 1 for each of the network terminals 2 to 5. Although this registration work is enormous when the number of network terminals is large, the network management server 1 according to the present invention is configured to easily perform this registration work. FIG. 2 is a block diagram showing the configuration of this network management server.

  The network management server 1 includes a network control unit 9 that communicates with network terminals 2 to 5 and the like connected to a LAN, a template processing unit 10, a file output processing unit 11, and a file input processing unit connected to the network control unit 9. 12 and an initial setting request processing unit 13. The network management server 1 also includes a database management unit 14 and a management database 16 for storing initial setting values of each network terminal.

  As will be described later, the management database 16 manages the registered network terminals, manages the registered terminal database for storing the initial setting values, the unregistered network terminals, and stores the initial setting values. In order to register, an unregistered terminal database operated by a procedure described later is created. Each of the above units is controlled by a main control unit 15 comprising a microprocessor.

  The template input processing unit 10 reads a template file that defines initial setting items and attributes for each network terminal model, extracts initial setting item names and attribute information, and sends them to the database management unit 14. The database management unit 14 creates a registered terminal database and an unregistered terminal database for each model using the MAC address item and the initial setting item as data items in the management database 16 based on the initial setting item name and attribute information of the template file. To do.

  As shown in FIG. 3, the template is a tabular file that defines initial item names and item attributes (data formats such as text and numerical values) for each model of network terminal. FIG. 3 shows models A and B as examples, but a similar template file is prepared for each model. This description rule is general and is described by item name = attribute. For example, “telephone number = numerical value [10 digits], essential item” is described.

  FIG. 4 is a diagram showing the configuration of the database 16 and includes a registered terminal database and an unregistered terminal database created for each model of network terminal. As shown in FIG. 4, the registered terminal database and the unregistered terminal database related to the model A have the same configuration, and the MAC address item and the initial setting item defined in the template file are used as data items. The same applies to the model B.

  Next, a case where the network administrator registers the initial setting value of the network terminal 2 (MAC address MAC1) of the model A in the database 14 will be described. The network administrator logs in to the network management server 1, operates the GUI provided in the network management server 1, and inputs the model name, MAC address (MAC1), and the values (a, b, c) of each initial setting item. Then, the input content is stored in the registered terminal database. FIG. 5 is a diagram showing a registered terminal database of the model A in this state.

  On the other hand, a case where the network management server 1 receives an initial setting request from the network terminals 3 and 4 not registered in the registered terminal database will be described. The initial setting request from the network terminals 3, 4 includes the MAC address (MAC 2, MAC 3) and model name (model A) of the network terminals 3, 4, and the initial setting processing unit 13 receives the network from the initial setting request. The MAC addresses and model names of the terminals 3 and 4 are extracted, and the MAC addresses MAC2 and MAC3 are automatically registered in the MAC address item of the unregistered terminal database of the model A.

  The same processing is performed on the unregistered database for each model for network terminals of other models. That is, when there is an initial setting request from an unregistered network terminal (MAC4) of model B, the MAC address MAC4 is automatically registered in the MAC address item of the model B unregistered terminal database.

  FIG. 6 is a diagram showing the unregistered terminal database in this state, and the values of the initial setting items other than the MAC address are blank.

  This unregistered terminal database can be exported from the network management server 1 by the network administrator, written with the setting values of the initial setting items other than the MAC address, re-imported into the network management server 1 and registered in the registered terminal database. it can. This procedure will be described below.

  File format that allows the network administrator to log in to the network management server 1, operate the GUI provided in the network management server 1, and export the unregistered terminal database of the model A and model B in which only the MAC address shown in FIG. 6 is recorded For example, when an instruction to output in a file format such as CSV format is given, the file output processing unit 11 converts the contents of the unregistered terminal database into a CSV (Comma Separated Value) format file format and is connected to the LAN. Download to the network administrator's personal computer (PC) 6.

  The network administrator opens the CSV file exported (downloaded) from the network management server 1 on the personal computer 6, and writes the initial setting values in the locations of the initial setting items of the network terminals 3 and 4. For example, the initial setting values of the network terminal 3 are d, e, and f in the order of the item names, and the initial setting values of the network terminal 4 are g, h, and i in the order of the item names.

  The table in which the initial set values are written is as shown in FIG. Thereafter, the file is converted into a CSV format file, and when the network management server 1 is input (imported) and uploaded, the file input processing unit 12 sends the uploaded CSV format file data to the database management unit 14 for database management. The unit 14 adds this data to the registered terminal database of the model A and the model B, and adds (registers) the initial setting values of the network terminals 2 to 4. FIG. 8 shows a registered terminal database and an unregistered terminal database in this state.

  Then, for the portion where the MAC address described in the CSV file exists in the unregistered terminal database, the database management unit 14 deletes the corresponding data from the unregistered terminal database of model A or model B. This completes the registration operation. A registered terminal database and an unregistered terminal database in this state are shown in FIG.

  FIG. 10 is a flowchart showing the above processing procedure. (A) is a procedure for creating a registered database and an unregistered database, (b) is a processing procedure for an initial setting request for a network terminal, and (c) is an initial procedure for a network terminal. It is a flowchart which shows each procedure which registers a setting value.

  In the flowchart of FIG. 10A, first, in step S10, the network administrator causes the network management server 1 to read a template file (see FIG. 3) defining initial setting items and attributes for each model of the network terminal. . The template input processing unit 10 extracts the initial setting item name and attribute information from the template file read in step S11 and sends it to the database management unit 14. The database management unit 14 is based on the initial setting item name and attribute information of the template file. Then, a registration terminal database for each model using the MAC address item and the initial setting item as data items is created in the management database 16 (see FIG. 4). In step S12, the database management unit 14 creates an unregistered terminal database in the management database in the same manner as in step S11 (see FIG. 4). In step S13, the process ends when the processing of the templates of all models is completed, and if not, the process returns to step S10.

  In the flowchart of FIG. 10B, when the network management server 1 receives an initial setting request (including the MAC address and model name) from the network terminal in step S20, the initial setting request processing unit 13 makes an initial setting request in step S21. Based on the included MAC address, it is checked whether the network terminal is registered in the registered terminal database via the database management unit 14, and if it is unregistered, the MAC address item in the unregistered database of the corresponding model is displayed in the MAC address field. The address is registered (see FIG. 6), and the process ends. If registered, the initial setting request processing unit 13 obtains the initial setting value of the corresponding network terminal from the registered terminal database (see FIG. 5) via the database management unit 14 in step S23 based on the MAC address and the model name. The data is read and transmitted to the corresponding network terminal via the network control unit 9 and the LAN, and the process ends.

  In the flowchart of FIG. 10C, first, the network administrator logs in to the network management server 1, operates the GUI provided in the network management server 1 in step S30, and is unregistered for each model in which only the MAC address is registered. An instruction to output the terminal database (see FIG. 6) in an exportable file format (such as CSV format) is issued. The file output processing unit 11 converts the contents of the unregistered terminal database into a CSV file format and downloads it to the personal computer (PC) 6 of the network administrator connected to the LAN.

Next, in step S31, the network administrator opens the CSV file exported (downloaded) from the network management server 1 on the personal computer 6 and writes the initial setting values of each network terminal (see FIG. 7). Then, the table in which the initial setting values are written is converted into a CSV format file in step S32, and the network management server 1 is input (imported) and uploaded. Then, the file input processing unit 12 sends the uploaded CSV file data to the database management unit 14, and the database management unit 14 adds this data to the registered terminal database for each model, and the network terminals 2-4. Add initial settings (see Figure 8)
In step S33, the file input processing unit 12 deletes the MAC address of the network terminal whose initial setting value is registered in the registered terminal database from the unregistered terminal database (see FIG. 9). If the processing of unregistered terminals of all models is not completed in step S34, the process returns to step S30, and if completed, the process ends. Of course, the above processing can also process unregistered terminal databases of all models at once, in which case the processing of step S34 can be skipped.

  Initial setting items of the template file include a telephone number, a user ID for logging in to the network management server 1, a password, a display name to be displayed at the destination, an outside line, an extension ringtone, a ringtone, etc. There are various setting items for the network with the network terminal, and if the IP phone model that is the network terminal is different, there are initial setting items for each function that the corresponding model has, and there are different initial setting items depending on the model. To do. Therefore, the network administrator's input work is divided by dividing the initial setting items into a common item that sets common contents that are not related to the network terminal, and a specific item that sets individual contents by the network terminal. In this case, input of common items can be performed in units of models, and input of specific items can be performed in units of terminals, so that input operations for common items can be performed efficiently without duplication.

  FIG. 11 is a diagram showing an item structure of the template file. Common items are items to which “common” is attached, and other items are specific items. This template file configuration shows a part of the setting items of the network terminal when a SIP (Session Initiation Protocol) server is used as the call control server. Common items include, for example, the domain name and proxy of the SIP server and its port number, and specific items include, for example, the primary line, external line number, user ID, password, and the like. Therefore, if “common” is input as flag information, the setting item can be set as a common item, and the network environment can be flexibly dealt with.

  This template file can be edited by the network administrator logging in to the network management server using WEB browser software, specifying the model to be edited and the template file name, and displaying the corresponding template file. FIG. 12 is a work selection screen displayed after login. On this screen, operations such as model name registration, common item input, specific item input, CSV output, backup, restore, MAC reading, logout, etc. are selected.

  When model name registration is selected, a registration screen shown in FIG. 13 is displayed, and a template file (see FIG. 11) of the corresponding model is registered by inputting the model name and operating the “Add” button. At the time of registration, default values are set for each item in the template file, and the template file name is assigned. (No.) is added. The file name can be referred to by operating the “reference” button, and the “update” button is operated when updating.

  When common item input is selected on the work item selection screen of FIG. 12, the common item setting screen of FIG. 14 is displayed. When the model name is selected by scrolling the “model name selection” field, only common items for the corresponding model are displayed. An input field in which is laid out is displayed. The network administrator inputs necessary setting items in the setting field of this screen. FIG. 14 shows a state where the input to the setting column is completed. This input screen is provided with a flag field indicating “valid” and “invalid” for each setting item, and the set item can be made “valid” by performing a check input in this flag field. Therefore, when changing the settings, it is possible to easily change from valid to invalid and invalid to valid by simply rewriting the valid / invalid flag information without having to input the setting contents consisting of multiple characters each time. Become.

  When the specific item input is selected on the work item selection screen of FIG. 12, the specific item setting screen of FIG. 15 is displayed. When the model name is selected by scrolling the “model name selection” field, the specific item setting of the corresponding model is set. Fields and input lines (input fields) are displayed. Specific items include the MAC address, telephone number (Primary), group, and IP address of the network terminal. In FIG. 15, these setting values are input to the input line. When the “add” button is operated, the setting value input to the input line is added to the specific item setting field.

  When updating the setting of a specific item for a desired network terminal, select the terminal displayed in the specific item setting field, enter the setting value to be updated in the input line, and operate the “Update” button By doing. By operating the “Export” button, the specific item setting data in which the initial value is set can be exported to another computer for work. The data format at this time is, for example, a CSV file format. In addition, the CSV file that has been exported to another computer and entered can be imported by operating the “Import” button. Also, by specifying the search target, setting the search condition in the input field, and operating the “Search” button, the specific item setting value of the desired network terminal is searched and displayed in the specific item setting field, and updated or deleted. Etc. can also be performed.

  FIG. 16 is a block diagram showing a configuration of a network management server that displays the above-described work screen. The network management server in FIG. 16 has basically the same configuration as the network management server in FIG. 2, but a display unit 17 not shown in the network management server in FIG. Can log in to the network management server using the WEB browser software, specify the model to be edited and the template file name, and display the corresponding template file on the display unit 17 for editing.

  The display processing unit 18 performs processing for displaying a registration screen and an input screen corresponding to the work selected on the work item selection screen displayed on the display unit 17. When the common item input or specific item input operation is selected, the display processing unit 18 displays the display unit as separate input screens as shown in the common item input screen of FIG. 14 and the specific item input screen of FIG. 18 is displayed. Therefore, the network administrator can visually recognize only the setting items to be worked on the screen, and the complexity of input can be reduced and input errors can be reduced. The template output processing unit 19 is a processing unit that exports a template.
