Description

Technical Field

[0001] The present disclosure relates to a maintenance operation system and a maintenance operation method.

Background Art

[0002] A network such as the Internet (hereinafter, appropriately referred to as "NW") is realized by connecting various NW devices constituting the NW to each other, and the NW devices are maintained and operated by a communications carrier on a daily basis.

[0003] For example, maintenance and operation of NW devices constituting an NW (hereinafter, referred to as "service NW") that provides a service through which user data flows is performed remotely via a DCN (Data Communication Network), which is a separate NW from the service NW. The DCN is a dedicated NW for maintenance and operation of NW devices and is disclosed, for example, in Non-Patent Document 1.

[0004] Here, related art regarding maintenance and operation work on NW devices via a DCN will be described. FIG. 1 is a diagram for explaining an example image of maintenance and operation work on an NW device in related art. In FIG. 1, it is assumed that a maintenance and operation work for adding a new NW device 81T is performed on a service NW 82 composed of a plurality of NW devices 81. Also, in FIG. 1, it is assumed that the plurality of NW devices 81 constituting the service NW 82 are connected to a DCN 83, and a control and monitoring system 84 is connected to the DCN 83.

[0005] As shown in Figure 1, in the related technology, first, the worker brings a PC (Personal Computer) and enters the station building where the new NW device 81T will be installed, and connects the PC to the management port (temporary connection port for maintenance work) 810 of the NW device 81T. Next, the worker performs the settings (S101) to connect the NW device 81T to DCN83. This allows the NW device 81T to be remotely controlled from the control and monitoring system 84 of the operation center. Next, the control and monitoring system 84 remotely performs the settings (S102) to integrate the NW device 81T into the service NW82. [Prior art documents] [Non-patent literature]

[Modes for carrying out the invention]

[0013] Embodiments of this disclosure will be described below with reference to the drawings. Note that the following description and drawings have been omitted and simplified as appropriate for clarity of explanation. Furthermore, the same elements are denoted by the same reference numerals in the following drawings, and redundant explanations have been omitted where necessary. Also, the specific numerical values ​​shown below are merely examples to facilitate understanding of this disclosure and are not limiting.

[0014] <Embodiment 1> <Image of Embodiment 1> First, let's describe the image of this first embodiment. Figure 2 is a diagram illustrating an example of maintenance and operation work for network equipment in this disclosure. In Figure 2, as in Figure 1, maintenance and operation work is performed to add a new network equipment 81T to the service network 82. Also in Figure 2, as in Figure 1, the multiple network equipment 81 constituting the service network 82 are connected to the DCN 83, and the control and monitoring system 84 is connected to the DCN 83.

[0015] As shown in Figure 2, this disclosure provides a mechanism that allows the network device 81T to access the internet 15 from the management port 810 using connectivity functions such as Bluetooth®, USB (Universal Serial Bus), 4G (Generation) / 5G, and WiFi®, which are standard features of the smart device 13.

[0016] In other words, in this disclosure, the worker brings a smart device 13 into the station building and uses the connection function of the smart device 13 to make the NW device 81T accessible to the internet 15 from the management port 810. In this state, the settings (S201) for integrating the NW device 81T into the service NW 82 are performed. As a result, maintenance and operation work on the NW device 81T can be performed even when the NW device 81T is not connected to DCN 83.

[0017] <Overview of Embodiment 1> Next, an overview of this first embodiment will be described. The operation of this embodiment 1 can be broadly divided into two phases: the preparation phase shown in Figure 3 and the automated execution phase shown in Figure 4.

[0018] First, let's explain the operation of the preparation phase. Figure 3 illustrates an example of the operation of the preparation phase in this disclosure. As shown in Figure 3, in the preparation phase, the work plan manager, who is responsible for the maintenance and operation work, first inputs work information into the command generator 11, including the type of maintenance and operation work and the work parameters, which are the parameters required for that maintenance and operation work.

[0019] The command generator 11 generates control instructions, web pages, and QR (Quick Response) codes (registered trademark) that are suitable for the input maintenance and operation tasks based on the input work information. These generated products are output for each network device to be controlled. In the following, it is assumed that the network device to be controlled is network device 81T.

[0020] The control instruction sheet is an electronic file containing information about the commands to be sent to the NW device 81T according to the entered maintenance operation procedure, as well as the order in which those commands should be sent. The web page is a web page for downloading the control instruction sheet. The QR code is a two-dimensional code that encodes the URL (Uniform Resource Locator) string for unique access to that web page.

[0021] Before a worker enters a building such as a central office or data center (hereinafter referred to as DC) where the NW device 81T is installed (or where a new NW device 81T will be installed) and begins work, the control instructions and web page are stored on a server 12 on the Internet 15, and a QR code is sent to the worker entering the work area. The QR code may be an electronic image or a printed document, but in Figure 3, it is shown as being printed on a paper work procedure manual brought by the worker.

[0022] Next, we will explain how the automated execution phase works. Figure 4 illustrates an example of the operation of the automated execution phase in this disclosure. As shown in Figure 4, the automation execution phase involves performing actual maintenance and operation tasks to which this disclosure applies.

[0023] First, the worker enters a building such as a station or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual with a QR code printed on it, the smart device 13, and the control adapter 14.

[0024] Next, the worker connects the network device 81T to the control adapter 14, and then connects the control adapter 14 to the smart device 13, following the procedures outlined in the work procedure manual. This allows the network device 81T to access the internet 15 via the control adapter 14 and the smart device 13.

[0025] Furthermore, the worker proceeds with the maintenance and operation work according to the procedures outlined in the work procedure manual. During the procedure, when scanning a QR code, the worker scans the QR code printed on the work procedure manual using the camera function of the smart device 13. A URL is then displayed on the screen of the smart device 13. When the worker touches the URL, the browser on the smart device 13 launches, automatically accesses the server 12 on the internet 15, and displays the web page on the screen of the smart device 13.

[0026] The operator confirms on the browser that "the control instruction sheet will be downloaded and commands will be automatically sent to the network device," and then presses the execute button on the web page, at which point the control instruction sheet is downloaded to the control adapter 14. Subsequently, the control adapter 14 sequentially sends commands to the network device 81T according to the contents of the control instruction sheet. In other words, the control adapter 14 sends the commands contained in the control instruction sheet to the network device 81T according to the information on the order of input contained in the control instruction sheet. This completes the maintenance and operation work. The following describes Embodiment 1 in detail.

[0027] <Details of Embodiment 1> First, the configuration of this embodiment 1 will be described. Figure 5 shows an example of the configuration of the maintenance and operation system 1 related to this disclosure. As shown in Figure 5, the maintenance operation system 1 comprises a command generator 11, a server 12, a smart device 13, and a control adapter 14. The following describes the individual components that make up the maintenance and operation system 1.

[0028] First, let's explain the command generator 11. Figure 6 illustrates an example of the items of work information that are input to the command generator 11 according to this disclosure.

[0029] As shown in Figure 6, each type of maintenance and operation work has its own set of necessary work parameters. Therefore, when the work planner inputs work information into the command generator 11, they first input the type of maintenance and operation work, and then input the necessary work parameters for that work. For example, when the work planner inputs "New installation of NW equipment" as the type of maintenance and operation work, they input "Installation location," "Mounting position," "Equipment product name," "Manufacturer vendor," "Equipment name," "IP (Internet Protocol) address," and "Config file" as work parameters. One method of inputting work information into the command generator 11 is to use a GUI (Graphical User Interface). Another method is to write multiple maintenance and operation work tasks and the work parameters for each of these tasks into an electronic file in CSV (Comma Separated Values) format and import that electronic file into the command generator 11.

[0030] The command generator 11 generates and outputs three things based on the input work information: a control instruction sheet containing commands according to the input maintenance operation procedure and information on the order in which those commands should be issued; a web page for downloading the control instruction sheet; and a QR code that encodes a string of URLs for uniquely accessing the web page.

[0031] The control instructions and web pages generated by the command generator 11 are stored in the server 12 on the Internet 15. It is assumed that the control instructions and web pages are output directly from the command generator 11 to the server 12 via wireless or wired communication. However, this is not limited to this; the control instructions and web pages may also be output to a separate device and then output from that separate device to the server 12.

[0032] Meanwhile, the QR code generated by the command generator 11 is sent to the worker entering the work area. For example, the QR code is printed on the paper work procedure manual that the worker brings with them, as shown in Figure 3.

[0033] Figure 7 illustrates an example of a work procedure manual related to this disclosure. As shown in Figure 7, the work procedure manual lists the tasks that the worker will perform on the day of work, in order of execution. In the example in Figure 7, the QR code output from the command generator 11 is pasted in the supplementary section next to the task for No. 11. Note that although Figure 3 shows the work procedure manual as being on paper, it may also be an electronic file.

[0034] Next, I will explain server 12. Server 12 is a server located on the Internet 15 and has the function of storing control instructions and web pages output from the command generator 11. Server 12 also has the function of transferring control instructions to the control adapter 14 via the smart device 13. For example, when an operator presses an execution button on a web page displayed on the screen of the smart device 13, Server 12 transfers the control instructions to the control adapter 14.

[0035] Next, the control adapter 14 and the smart device 13 will be described. The control adapter 14 is a palm-sized, general-purpose miniature device that acts as a relay for communication between the network device 81T and the smart device 13, and also sends commands to the network device 81T according to the control instruction sheet. For example, the control adapter 14 may incorporate general-purpose software that has the function of sequentially sending commands based on the contents of the control instruction sheet.

[0036] Here, the connection protocol between the control adapter 14 and the network device 81T, as well as the commands to be sent to the network device 81T and the order in which those commands are sent, may vary depending on the vendor and product specifications. However, all of these differences are absorbed within the control instruction manual.

[0037] Smart devices 13 are general-purpose products such as smartphones and tablets that workers possess and carry with them for communication with relevant parties. Here, the smart device 13 typically has wireless connectivity to access the internet 15 via a 4G / 5G network or Wi-Fi.

[0038] Figure 8 illustrates an example of a method for connecting the smart device 13 and the control adapter 14 according to this disclosure. As shown in Figure 8, in step S301, the network device 81T and the control adapter 14 are connected. For example, the control adapter 14 is physically connected to the management port 810 that controls the network device 81T using a cable specified by the manufacturer of the network device 81T (such as an Ethernet® cable or a serial cable).

[0039] Furthermore, in step S302, the control adapter 14 and the smart device 13 are connected. For example, by pressing the Bluetooth connection button on the smart device 13, the control adapter 14 and the smart device 13 are connected via Bluetooth. However, Bluetooth connection is not suitable for sending and receiving large amounts of data. Therefore, if such transmission and reception is required, the control adapter 14 and the smart device 13 should be connected using a USB cable.

[0040] Once the connections described in steps S301 and S302 are completed, the NW device 81T will be able to access the internet 15 via the control adapter 14 and the smart device 13.

[0041] Furthermore, the smart device 13 is equipped with a camera function as standard. The camera function is used by the worker to read the QR code attached to the work procedure manual. When the QR code is read, a URL is displayed on the screen, and when the worker touches the URL, the browser is launched, accesses the server 12 on the internet 15, and a web page is displayed on the screen. When the worker presses the execute button on the web page, the control instruction manual is downloaded to the control adapter 14 via the smart device 13.

[0042] Next, the operation of this embodiment 1 will be described. First, let's explain the operation of the preparation phase. As shown in Figure 3, first, the work plan manager inputs work information into the command generator 11, including the type of maintenance operation work and the work parameters required for that maintenance operation work. The command generator 11 then generates a control instruction sheet, a web page, and a QR code based on the input work information.

[0043] Here, we will explain in detail the operation of the command generator 11. Figure 9 is a diagram illustrating an example of the operation of the command generator 11 according to this disclosure. As shown in Figure 9, the command generator 11 generates a web page and control instructions by performing conversions such as those in steps S401, S402, and S403 on the input work information. At this time, the command generator 11 generates a web page dedicated to the NW device 81T based on the information of the type of maintenance operation, installation location, and mounting position that is passed as work information. In addition, the command generator 11 generates a control instruction document dedicated to the NW device 81T, which is a string of unique commands based on the specifications of the device product, arranged in a unique input order, based on the information of the device product, manufacturer, device name, IP address, and Config file that is passed as work information. Furthermore, the command generator 11 generates a QR code by encoding a string of URLs that uniquely access a web page.

[0044] The control instructions and web pages generated by the command generator 11 are stored on the server 12 on the internet 15. Additionally, the QR code generated by the command generator 11 is sent to the worker. For example, the QR code is printed in the supplementary section next to the relevant work procedure on the paper work procedure manual that the worker brings with them.

[0045] Next, we will explain how the automated execution phase works. As shown in Figure 4, first, the worker enters a building such as a station or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual, smart device 13, and control adapter 14.

[0046] Next, the operator performs connection work to connect the network device 81T to the control adapter 14, and then connects the control adapter 14 to the smart device 13. Once these connection tasks are completed, the network device 81T will be able to access the internet 15 via the control adapter 14 and the smart device 13.

[0047] The subsequent steps will be explained using the installation of a new NW device 81T as an example, following the work procedure shown in Figure 7, Figure 10, and Figure 11. Figure 10 is a diagram illustrating an example of screen transitions for the smart device 13 according to this disclosure. Figure 11 is a diagram illustrating an example of operation of the automated execution phase by the smart device 13, server 12, and control adapter 14 according to this disclosure.

[0048] Here, the worker has completed the connection work of connecting the NW device 81T and the control adapter 14, and the connection work of connecting the control adapter 14 and the smart device 13, as described above. Therefore, it is assumed that the steps up to the work content of No. 10 in Figure 7 have been completed.

[0049] Next, the worker, following the instructions for step No. 11 in Figure 7, uses the camera function of the smart device 13 (a tablet in Figure 7) to scan the QR code attached to the supplementary section. A URL is then displayed on the screen of the smart device 13 (step S501 in Figure 10).

[0050] Next, the operator touches the URL displayed on the screen of the smart device 13, following the instructions for step No. 12 in Figure 7. The browser on the smart device 13 then launches, accesses the server 12 on the internet 15, and displays a web page on the screen of the smart device 13 (step S502 in Figure 10). At this time, since the QR code read above is an encoded string of a URL that uniquely accesses the web page dedicated to the NW device 81T, the web page displayed in step S502 in Figure 10 is the web page dedicated to the NW device 81T. Therefore, this web page dedicated to the NW device 81T displays text specific to the NW device 81T (in the example in Figure 10, "Initial files for Yokohama Station Rack:3 Shelf:2 will be installed").

[0051] Next, the worker confirms that the text written in the supplementary column to the side is displayed on the screen of the smart device 13, in accordance with the work procedure in No. 13 of Figure 7. This allows the worker to confirm that the correct process is executed on the NW device (NW device 81T) described in the work procedure in No. 9 of Figure 7.

[0052] Next, the operator presses the execute button on the web page displayed in step S502 of Figure 10, following the instructions for step No. 14 in Figure 7. Then, all subsequent command input operations to the NW device 81T are performed automatically without any operator intervention.

[0053] In practice, when the execute button on the web page displayed on the screen of the smart device 13 is pressed (step S601 in Figure 11), the process associated with this execute button, that is, the process of transferring a control instruction from the server 12 to the control adapter 14 via the smart device 13, is initiated (step S602 in Figure 11).

[0054] When the control adapter 14 receives a control instruction from the server 12, it automatically sends commands sequentially to the network device 81T according to the contents of the control instruction (step S603 in Figure 11). The progress of the automatic command sending from the control adapter 14 is displayed in real time on a web page on the smart device 13 screen (step S503 in Figure 10). Therefore, the operator can know the progress and completion of the automatic command sending. In this way, all control of maintenance and operation work for the network device 81T can be automated.

[0055] As described above, according to this embodiment 1, the command generator 11 receives work information, including the type of maintenance operation and the work parameters required for that maintenance operation. Based on the input work information, the command generator 11 generates a control instruction sheet containing information on the commands to be sent to the NW device 81T to be controlled and the order in which those commands should be sent, a web page for downloading the control instruction sheet, and a QR code that encodes the URL string for accessing the web page. The control instruction sheet and web page are stored on a server 12 on the internet 15, and the QR code is attached to the work procedure sheet. The control adapter 14 is connected to the NW device 81T and the smart device 13, enabling the NW device 81T to access the internet 15. When the operator reads the QR code attached to the work procedure sheet using the camera function of the smart device 13, the URL is displayed on the screen. When the operator touches the URL, the smart device 13 accesses the server 12 and displays the web page on the screen. When the operator presses the execute button on the web page, a control instruction sheet is downloaded from the server 12 to the control adapter 14. The control adapter 14 then sequentially sends commands to the network device 81T according to the control instruction sheet.

[0056] Therefore, according to this embodiment 1, maintenance and operation work on the NW device 81T can be performed without connecting the NW device 81T to the DCN 83. Furthermore, maintenance and operation work on the NW device 81T can be performed as long as the smart device 13 has access to the internet 15. This reduces the constraints on the work location where maintenance and operation work can be performed. In addition, if the control adapter 14 is connected to the NW device 81T and the smart device 13 can be connected to the control adapter 14, then, for example, a worker does not need to enter the station building to perform software update work on the NW device 81T, but can perform it in the office. In this case, since the worker does not need to move to the station building, maintenance and operation work can be performed very efficiently.

[0057] Furthermore, this first embodiment also provides the following additional benefits. Other effects 1: Some related technologies involve manually inputting commands to the NW device 81T. In contrast, according to this embodiment 1, the command input process to the NW device 81T is automated. This significantly reduces the time required for maintenance and operation work. Furthermore, since the automated command input process can be performed in parallel for multiple NW devices 81T, this also contributes greatly to reducing work time.

[0058] Other effects 2: Some related technologies include a function that allows the NW device 81T itself to acquire an IP address, read control data, and process it. However, whether or not the NW device 81T has this function depends on the vendor and product specifications, so maintenance and operation work can only be performed on some of the NW devices 81T that have this function. In contrast, according to this embodiment 1, the NW device 81T does not need to have the above function, so maintenance and operation work can be performed uniformly on all NW devices 81T using the same method. Therefore, maintenance and operation work can be simplified.

[0059] Other effects 3: The maintenance and operation procedures for the NW device 81T vary depending on the product and vendor. However, according to this embodiment 1, since the work parameters input to the command generator 11 include product and vendor information, the command generator 11 can generate control instructions that are suitable for the NW device 81T's product and vendor. In other words, the command generator 11 can absorb the differences between products and vendors. Therefore, maintenance and operation procedures for the NW device 81T can be performed even if the product or vendor is different. Furthermore, even when adopting a new product or a new vendor, development costs can be reduced because only the control instruction generation logic of the command generator 11 needs to be updated.

[0060] Other effects 4: According to this embodiment 1, the preliminary connection work is extremely simple, consisting only of connecting the control adapter 14 to the NW device 81T via Bluetooth or the like, and connecting the control adapter 14 to the smart device 13 with a cable. Furthermore, all commands to be entered into the NW device 81T are expressed in the control instruction manual. Therefore, operators only need to uniformly perform the same procedure as the work content of No. 11-14 in Figure 7, regardless of the type of maintenance and operation work. This minimizes the learning cost required to train operators in advance.

[0061] Other effects 5: According to this embodiment 1, the only actions required of the worker are to read the QR code with the camera function of the smart device 13, touch the URL, and press the execute button; they do not need to input any strings or numbers. Therefore, errors in maintenance and operation work caused by worker input errors can be completely eliminated. As a result, regardless of who the worker is, equally high-quality maintenance and operation work can be performed.

[0062] Other effects 6: As mentioned above, some related technologies involve manually inputting commands to the NW device 81T. However, if an incorrect command is input to the NW device 81T, in the worst case, it could affect services running on the service NW82. Therefore, it is extremely important to input the correct command to the correct NW device 81T, and reliability is required for maintenance and operation work on the NW device 81T. In contrast, according to this embodiment 1, as explained using No. 9 and No. 13 in Figure 7 and step S502 in Figure 10, the operator can verify the processing performed on the NW device 81T. This allows the operator to verify that the correct command is input to the correct NW device 81T, thus ensuring the reliability of maintenance and operation work through the operator's observation.

[0063] Other effects 7: In the related technology shown in Figure 1, there were tasks that could only be performed by on-site workers entering the station building and tasks that could only be performed by remote workers, requiring the securing of workers both on-site and remotely. In contrast, according to this embodiment 1, all procedures of maintenance and operation work can be completed by on-site workers alone, thus optimizing the number of workers that need to be secured.

[0064] Other effects 8: According to this embodiment 1, the smart device 13 utilizes only functions that are standard on many general-purpose smart devices, such as Bluetooth connectivity, USB connectivity, a camera, a QR code reading function, and a browser function. Therefore, a general-purpose product itself can be used as the smart device 13. Furthermore, the smart device 13 is not dependent on the type of OS (Operating System) and does not require any special configuration changes. In addition, the smart device 13 does not require the installation of a dedicated application. As a result, the barrier to implementing the method disclosed herein can be lowered.

[0065] <Embodiment 2> <Image of Embodiment 2> First, let's describe the image of this second embodiment. Figure 12 is a diagram illustrating an example of maintenance and operation work for network equipment in this disclosure. In Figure 12, as in Figure 1, maintenance and operation work is performed to add a new network equipment 81T to the service network 82. Also in Figure 12, as in Figure 1, the multiple network equipment 81 constituting the service network 82 are connected to the DCN 83, and the control and monitoring system 84 is connected to the DCN 83.

[0066] As shown in Figure 12, in this disclosure, the control adapter 14 has a mechanism for holding control instructions for integrating the NW device 81T into the service NW 82. In other words, in this disclosure, the worker enters the station building with the control adapter 14 containing the control instructions. Then, the setup (S201) for integrating the NW device 81T into the service NW 82 is performed. As a result, maintenance and operation work on the NW device 81T can be performed even when the NW device 81T is not connected to the DCN 83.

[0067] <Overview of Embodiment 2> Next, we will describe the outline of this second embodiment. The operation of this second embodiment can be broadly divided into two phases: the preparation phase shown in Figure 13 and the automated execution phase shown in Figure 14.

[0068] First, let's explain the operation of the preparation phase. Figure 13 illustrates an example of the operation of the preparation phase in this disclosure. As shown in Figure 13, in the preparation phase, the work plan manager, who is responsible for the maintenance and operation work, first inputs work information into the command generator 11, including the type of maintenance and operation work and the work parameters, which are the parameters required for that maintenance and operation work.

[0069] The command generator 11 generates control instructions, web pages, and QR codes that are appropriate for the input maintenance and operation tasks based on the input work information. These generated items are output for each network device to be controlled. In the following, it is assumed that the network device to be controlled is network device 81T.

[0070] The control instruction sheet is an electronic file containing information about the commands to be sent to the NW device 81T according to the entered maintenance operation procedure, as well as the order in which those commands should be sent. The web page is the web page for executing that control instruction sheet. The QR code is a two-dimensional code that encodes the URL string for unique access to that web page.

[0071] Before a worker enters a building such as a station or data center where the NW device 81T is installed (or where a new NW device 81T will be installed) and begins work, the control instructions and web page are stored in the control adapter 14, and the QR code is sent to the worker entering the work area. The QR code may be an electronic image or a printed document, but in Figure 13, it is shown as being printed on a paper work procedure manual brought by the worker.

[0072] Next, we will explain how the automated execution phase works. Figure 14 illustrates an example of the operation of the automated execution phase in this disclosure. As shown in Figure 14, the automation execution phase involves performing actual maintenance and operation tasks to which this disclosure applies.

[0073] First, the worker enters a building such as a station or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual with a QR code printed on it, the smart device 13, and the control adapter 14.

[0074] Next, the worker connects the network device 81T to the control adapter 14, and then connects the control adapter 14 to the smart device 13, following the procedures outlined in the work procedure manual. This allows the network device 81T to access the control adapter 14.

[0075] Furthermore, the worker proceeds with the maintenance and operation work according to the procedures outlined in the work procedure manual. During the procedure, when scanning a QR code, the worker scans the QR code printed on the work procedure manual using the camera function of the smart device 13. A URL is then displayed on the screen of the smart device 13. When the worker touches the URL, the browser on the smart device 13 launches, automatically accesses the control adapter 14, and displays a web page on the screen of the smart device 13.

[0076] The operator confirms on the browser that "commands will be automatically sent to the network device" and presses the execute button on the web page. The control adapter 14 then sequentially sends commands to the network device 81T according to the contents of the control instruction document. In other words, the control adapter 14 sends the commands included in the control instruction document to the network device 81T according to the information on the order of input included in the control instruction document. This completes the maintenance and operation work. The second embodiment will now be described in detail.

[0077] <Details of Embodiment 2> First, the configuration of this second embodiment will be described. Figure 15 shows an example of the configuration of the maintenance and operation system 2 related to this disclosure. As shown in Figure 15, the maintenance operation system 2 includes a command generator 11, a smart device 13, and a control adapter 14. The following describes the individual components that make up the maintenance and operation system 2.

[0078] First, let's explain the command generator 11. As shown in Figure 6, each type of maintenance and operation work has its own set of work parameters. Therefore, when the work planner inputs work information into the command generator 11, they first input the type of maintenance and operation work, and then input the work parameters required for that work. For example, when the work planner inputs "New installation of NW equipment" as the type of maintenance and operation work, they input "Installation location," "Mounting position," "Equipment product name," "Manufacturer vendor," "Equipment name," "IP address," and "Config file" as work parameters. One method of inputting work information into the command generator 11 is to input it using the GUI. Another method is to write multiple maintenance and operation work tasks and the work parameters for each of these tasks into an electronic file in CSV format and import that electronic file into the command generator 11.

[0079] The command generator 11 generates and outputs three things based on the input work information: a control instruction sheet containing commands according to the input maintenance operation procedure and information on the order in which those commands should be issued; a web page for executing the control instruction sheet; and a QR code that encodes a URL string for uniquely accessing the web page.

[0080] The control instructions and web pages generated by the command generator 11 are stored in the control adapter 14. It is assumed that the control instructions and web pages are directly output from the command generator 11 to the control adapter 14 via wireless or wired communication. However, this is not limited to this configuration; the control instructions and web pages may also be output to a separate device and then output from that separate device to the control adapter 14.

[0081] Meanwhile, the QR code generated by the command generator 11 is sent to the worker entering the work area. For example, the QR code is printed on the paper work procedure manual that the worker brings with them, as shown in Figure 13.

[0082] As shown in Figure 7, the work procedure manual lists the tasks that the worker will perform on the day of work, in order of execution. In the example in Figure 7, the QR code output from the command generator 11 is pasted in the supplementary section next to the task for No. 11. Note that although Figure 13 shows the work procedure manual as being on paper, it may also be an electronic file.

[0083] Next, the control adapter 14 and the smart device 13 will be described. The control adapter 14 is a palm-sized, general-purpose miniature device that serves to relay communication between the network device 81T and the smart device 13, store control instructions, and input commands to the network device 81T according to the control instructions. For example, the control adapter 14 may incorporate general-purpose software that has the function of sequentially inputting commands based on the contents of the control instructions.

[0084] Here, the connection protocol between the control adapter 14 and the network device 81T, as well as the commands to be sent to the network device 81T and the order in which those commands are sent, may vary depending on the vendor and product specifications. However, all of these differences are absorbed within the control instruction manual.

[0085] Smart devices 13 are general-purpose products such as smartphones and tablets that workers possess and carry with them for communication with relevant parties. The smart device 13 can access the control adapter 14 via Bluetooth or a USB cable.

[0086] Figure 16 is a diagram illustrating an example of a method for connecting the smart device 13 and the control adapter 14 according to this disclosure. As shown in Figure 16, in step S701, the network device 81T and the control adapter 14 are connected. For example, the control adapter 14 is physically connected to the management port 810 that controls the network device 81T using a cable specified by the manufacturer of the network device 81T (such as an Ethernet cable or a serial cable).

[0087] Furthermore, in step S702, the control adapter 14 and the smart device 13 are connected. For example, by pressing the Bluetooth connection button on the smart device 13, the control adapter 14 and the smart device 13 are connected via Bluetooth. However, Bluetooth connection is not suitable for sending and receiving large amounts of data. Therefore, if such transmission and reception is required, the control adapter 14 and the smart device 13 should be connected using a USB cable.

[0088] Furthermore, the smart device 13 is equipped with a camera function as standard. The camera function is used by the worker to read the QR code attached to the work procedure manual. When the QR code is read, a URL is displayed on the screen, and when the worker touches the URL, the browser is launched, accesses the control adapter 14, and a web page is displayed on the screen. When the worker presses the execute button on the web page, the control adapter 14 sequentially sends commands to the network device 81T according to the contents of the control instruction manual.

[0089] Next, the operation of this second embodiment will be described. First, let's explain the operation of the preparation phase. As shown in Figure 13, first, the work plan manager inputs work information into the command generator 11, including the type of maintenance operation work and the work parameters required for that maintenance operation work. The command generator 11 then generates a control instruction sheet, a web page, and a QR code based on the input work information.

[0090] Here, we will explain in detail the operation of the command generator 11. As shown in Figure 9, the command generator 11 generates a web page and control instructions by performing conversions such as those in steps S401, S402, and S403 on the input work information. At this time, the command generator 11 generates a web page dedicated to the NW device 81T based on the information of the type of maintenance operation, installation location, and mounting position that is passed as work information. In addition, the command generator 11 generates a control instruction document dedicated to the NW device 81T, which is a string of unique commands based on the specifications of the device product, arranged in a unique input order, based on the information of the device product, manufacturer, device name, IP address, and Config file that is passed as work information. Furthermore, the command generator 11 generates a QR code by encoding a string of URLs that uniquely access a web page.

[0091] The control instructions and web pages generated by the command generator 11 are stored in the control adapter 14. Additionally, the QR code generated by the command generator 11 is sent to the worker. For example, the QR code is printed in the supplementary section next to the relevant work item on the paper work procedure manual that the worker brings with them.

[0092] Next, we will explain how the automated execution phase works. As shown in Figure 14, first, the worker enters a building such as a station or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual, smart device 13, and control adapter 14.

[0093] Next, the operator performs connection work to connect the network device 81T to the control adapter 14, and then connects the control adapter 14 to the smart device 13. Once these connection works are completed, the smart device 13 will be able to access the network device 81T via the control adapter 14.

[0094] The subsequent steps will be explained using the installation of the new NW device 81T as an example, following the work procedure shown in Figure 7 and Figure 10. Here, the worker has completed the connection work of connecting the NW device 81T and the control adapter 14, and the connection work of connecting the control adapter 14 and the smart device 13, as described above. Therefore, it is assumed that the steps up to the work content of No. 10 in Figure 7 have been completed.

[0095] Next, the worker, following the instructions for step No. 11 in Figure 7, uses the camera function of the smart device 13 (a tablet in Figure 7) to scan the QR code attached to the supplementary section. A URL is then displayed on the screen of the smart device 13 (step S501 in Figure 10).

[0096] Next, the operator touches the URL displayed on the screen of the smart device 13, following the instructions for step No. 12 in Figure 7. The browser on the smart device 13 then launches, accesses the control adapter 14, and displays a web page on the screen of the smart device 13 (step S502 in Figure 10). At this time, since the QR code read above is an encoded string of a URL that uniquely accesses the web page dedicated to the NW device 81T, the web page displayed in step S502 in Figure 10 is the web page dedicated to the NW device 81T. Therefore, this web page dedicated to the NW device 81T displays text specific to the NW device 81T (in the example in Figure 10, "Initial files for Yokohama Station Rack:3 Shelf:2 will be installed").

[0097] Next, the worker confirms that the text written in the supplementary column to the side is displayed on the screen of the smart device 13, in accordance with the work procedure in No. 13 of Figure 7. This allows the worker to confirm that the correct process is executed on the NW device (NW device 81T) described in the work procedure in No. 9 of Figure 7.

[0098] Next, the operator presses the execute button on the web page displayed in step S502 of Figure 10, following the instructions for step No. 14 in Figure 7. Then, all subsequent command input operations to the NW device 81T are performed automatically without any operator intervention.

[0099] In practice, when the execution button on the web page displayed on the smart device 13 is pressed, the process associated with this execution button is initiated. This process involves the control adapter 14 automatically sending commands sequentially to the network device 81T according to the control instructions. The progress of the automatic command sending from the control adapter 14 is displayed in real time on the web page on the smart device 13 (step S503 in Figure 10). Therefore, the operator can know the progress and completion of the automatic command sending. In this way, all control of maintenance and operation work for the network device 81T can be automated.

[0100] As described above, according to this embodiment 2, the command generator 11 receives work information, including the type of maintenance operation and the work parameters required for that maintenance operation. Based on the input work information, the command generator 11 generates a control instruction sheet containing information on the commands to be sent to the NW device 81T to be controlled and the order in which those commands should be sent, a web page for executing the control instruction sheet, and a QR code that encodes the URL string for accessing the web page. The control instruction sheet and web page are stored in the control adapter 14, and the QR code is attached to the work procedure sheet. The control adapter 14 is connected to the NW device 81T and the smart device 13. When the operator reads the QR code attached to the work procedure sheet using the camera function of the smart device 13, the URL is displayed on the screen. When the operator touches the URL, the smart device 13 accesses the control adapter 14 and displays the web page on the screen. When the operator presses the execute button on the web page, the control adapter 14 sequentially sends commands to the network device 81T according to the control instructions.

[0101] Therefore, according to this second embodiment, maintenance and operation work on the NW device 81T can be performed without connecting the NW device 81T to the DCN83. Furthermore, if the control adapter 14 is connected to the NW device 81T and the smart device 13 and the control adapter 14 can be connected, then, for example, a worker does not need to enter the station building to perform software update work on the NW device 81T, but can perform it in the office. In this case, since the worker does not need to travel to the station building, maintenance and operation work can be performed very efficiently. Furthermore, this second embodiment also provides the same effects as the first embodiment described above (the other effects 1 to 8 described above).

[0102] <Embodiment 3> <Image of Embodiment 3> First, let's describe the image of this third embodiment. Figure 17 is a diagram illustrating an example of maintenance and operation work for network equipment in this disclosure. In Figure 17, as in Figure 1, maintenance and operation work is performed to add a new network equipment 81T to the service network 82. Also in Figure 17, as in Figure 1, the multiple network equipment 81 constituting the service network 82 are connected to the DCN 83, and the control and monitoring system 84 is connected to the DCN 83.

[0103] As shown in Figure 17, this disclosure provides a mechanism that allows the network device 81T to access the internet 15 from the management port 810 using connectivity functions such as Bluetooth, USB, 4G / 5G, and WiFi, which are standard features of the smart device 13.

[0104] In other words, in this disclosure, the worker brings a smart device 13 into the station building and uses the connection function of the smart device 13 to make the NW device 81T accessible to the internet 15 from the management port 810. In this state, the settings (S201) for integrating the NW device 81T into the service NW 82 are performed. As a result, maintenance and operation work on the NW device 81T can be performed even when the NW device 81T is not connected to DCN 83.

[0105] <Overview of Embodiment 3> Next, an overview of this third embodiment will be described. The operation of this third embodiment can be broadly divided into two phases: the preparation phase shown in Figure 3 and the automated execution phase shown in Figure 18.

[0106] First, let's explain the operation of the preparation phase. As shown in Figure 3, in the preparation phase, the work plan manager, who is responsible for the maintenance and operation work, first inputs work information into the command generator 11, including the type of maintenance and operation work and the work parameters, which are the parameters required for that maintenance and operation work.

[0107] The command generator 11 generates control instructions, web pages, and QR codes that are suitable for the input maintenance and operation tasks based on the input work information. These generated items are output for each network device to be controlled. In the following, it is assumed that the network device to be controlled is network device 81T.

[0108] The control instruction sheet is an electronic file containing information about the commands to be sent to the NW device 81T according to the entered maintenance operation procedure, as well as the order in which those commands should be sent. The web page is a web page for downloading the control instruction sheet. The QR code is a two-dimensional code that encodes the URL string for unique access to that web page.

[0109] Before a worker enters a building such as a station or data center where the NW device 81T is installed (or where a new NW device 81T will be installed) and begins work, the control instructions and web page are stored on a server 12 on the internet 15, and a QR code is sent to the worker entering the work area. The QR code may be an electronic image or a printed document, but in Figure 3, it is shown as being printed on a paper work procedure manual brought by the worker.

[0110] Next, we will explain how the automated execution phase works. Figure 18 illustrates an example of the operation of the automated execution phase in this disclosure. As shown in Figure 18, the automation execution phase involves performing actual maintenance and operation tasks to which this disclosure applies.

[0111] First, the worker enters the building, such as a station or data center, where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual with a QR code printed on it and the smart device 13.

[0112] Next, the worker directly connects the network device 81T and the smart device 13 according to the procedures in the work procedure manual. This allows the network device 81T to access the internet 15 via the smart device 13.

[0113] Furthermore, the worker proceeds with the maintenance and operation work according to the procedures outlined in the work procedure manual. During the procedure, when scanning a QR code, the worker scans the QR code printed on the work procedure manual using the camera function of the smart device 13. A URL is then displayed on the screen of the smart device 13. When the worker touches the URL, the browser on the smart device 13 launches, automatically accesses the server 12 on the internet 15, and displays the web page on the screen of the smart device 13.

[0114] The operator confirms on the browser that "the control instruction sheet will be downloaded and commands will be automatically sent to the network device," and then presses the execute button on the web page, at which point the control instruction sheet is downloaded to the smart device 13. Subsequently, the smart device 13 sequentially sends commands to the network device 81T according to the contents of the control instruction sheet. In other words, the smart device 13 sends the commands contained in the control instruction sheet to the network device 81T according to the command sequence information contained in the control instruction sheet. This completes the maintenance and operation work. The third embodiment will now be described in detail.

[0115] <Details of Embodiment 3> First, the configuration of this third embodiment will be described. Figure 19 shows an example of the configuration of the maintenance and operation system 3 related to this disclosure. As shown in Figure 19, the maintenance and operation system 3 comprises a command generator 11, a server 12, and a smart device 13. The following describes the individual components that make up the maintenance and operation system 3.

[0116] First, let's explain the command generator 11. As shown in Figure 6, each type of maintenance and operation work has its own set of work parameters. Therefore, when the work planner inputs work information into the command generator 11, they first input the type of maintenance and operation work, and then input the work parameters required for that work. For example, when the work planner inputs "New installation of NW equipment" as the type of maintenance and operation work, they input "Installation location," "Mounting position," "Equipment product name," "Manufacturer vendor," "Equipment name," "IP address," and "Config file" as work parameters. One method of inputting work information into the command generator 11 is to input it using the GUI. Another method is to write multiple maintenance and operation work tasks and the work parameters for each of these tasks into an electronic file in CSV format and import that electronic file into the command generator 11.

[0117] The command generator 11 generates and outputs three things based on the input work information: a control instruction sheet containing commands according to the input maintenance operation procedure and information on the order in which those commands should be issued; a web page for downloading the control instruction sheet; and a QR code that encodes a string of URLs for uniquely accessing the web page.

[0118] The control instructions and web pages generated by the command generator 11 are stored in the server 12 on the Internet 15. It is assumed that the control instructions and web pages are output directly from the command generator 11 to the server 12 via wireless or wired communication. However, this is not limited to this; the control instructions and web pages may also be output to a separate device and then output from that separate device to the server 12.

[0119] Meanwhile, the QR code generated by the command generator 11 is sent to the worker entering the work area. For example, the QR code is printed on the paper work procedure manual that the worker brings with them, as shown in Figure 3.

[0120] As shown in Figure 7, the work procedure manual lists the tasks that the worker will perform on the day of work, in order of execution. In the example in Figure 7, the QR code output from the command generator 11 is pasted in the supplementary section next to the task for No. 11. Note that although Figure 3 shows the work procedure manual as being on paper, it may also be an electronic file.

[0121] Next, I will explain server 12. Server 12 is a server located on the Internet 15 and has the function of storing control instructions and web pages output from the command generator 11. Server 12 also has the function of transferring control instructions to the smart device 13. For example, when an operator presses an execution button on a web page displayed on the screen of the smart device 13, Server 12 transfers the control instructions to the smart device 13.

[0122] Next, I will explain smart device 13. Smart devices 13 are general-purpose products such as smartphones and tablets that workers possess and carry with them for communication with relevant parties. Smart devices 13 typically have wireless connectivity to access the internet 15 via 4G / 5G networks or Wi-Fi.

[0123] Furthermore, the smart device 13 is connected to the network device 81T and sends commands to the network device 81T according to the control instructions. For example, the smart device 13 may have general-purpose software incorporated that has the function of sequentially sending commands based on the contents of the control instructions.

[0124] Here, the connection protocol between the smart device 13 and the network device 81T, as well as the commands to be sent to the network device 81T and the order in which those commands are sent, may differ depending on the vendor and product specifications. However, all of these differences are absorbed within the control instruction document.

[0125] Figure 20 is a diagram illustrating an example of a method for connecting the smart device 13 according to this disclosure. As shown in Figure 20, in step S801, the network device 81T and the smart device 13 are connected. For example, the smart device 13 is physically connected to the management port 810 that controls the network device 81T using a cable specified by the manufacturer of the network device 81T (such as an Ethernet cable or a serial cable). Once the connection in step S801 is completed, the network device 81T can access the internet 15 via the smart device 13.

[0126] Furthermore, the smart device 13 is equipped with a camera function as standard. The camera function is used by the worker to read the QR code attached to the work procedure manual. When the QR code is read, a URL is displayed on the screen, and when the worker touches the URL, the browser is launched, accesses the server 12 on the internet 15, and a web page is displayed on the screen. When the worker presses the execute button on the web page, the control instruction manual is downloaded to the smart device 13.

[0127] Next, the operation of this third embodiment will be described. First, let's explain the operation of the preparation phase. As shown in Figure 3, first, the work plan manager inputs work information into the command generator 11, including the type of maintenance operation work and the work parameters required for that maintenance operation work. The command generator 11 then generates a control instruction sheet, a web page, and a QR code based on the input work information.

[0128] Here, we will explain in detail the operation of the command generator 11. As shown in Figure 9, the command generator 11 generates a web page and control instructions by performing conversions such as those in steps S401, S402, and S403 on the input work information. At this time, the command generator 11 generates a web page dedicated to the NW device 81T based on the information of the type of maintenance operation, installation location, and mounting position that is passed as work information. In addition, the command generator 11 generates a control instruction document dedicated to the NW device 81T, which is a string of unique commands based on the specifications of the device product, arranged in a unique input order, based on the information of the device product, manufacturer, device name, IP address, and Config file that is passed as work information. Furthermore, the command generator 11 generates a QR code by encoding a string of URLs that uniquely access a web page.

[0129] The control instructions and web pages generated by the command generator 11 are stored on the server 12 on the internet 15. Additionally, the QR code generated by the command generator 11 is sent to the worker. For example, the QR code is printed in the supplementary section next to the relevant work procedure on the paper work procedure manual that the worker brings with them.

[0130] Next, we will explain how the automated execution phase works. As shown in Figure 18, first, the worker enters a building such as a central office or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing the work procedure manual and smart device 13 with them.

[0131] Next, the operator performs connection work to connect the network device 81T and the smart device 13. Once these connection tasks are completed, the network device 81T will be able to access the internet 15 via the smart device 13.

[0132] The subsequent steps will be explained using the installation of the new NW device 81T as an example, following the work procedure shown in Figure 7 and Figure 10. Here, the worker has completed the connection work of connecting the NW device 81T and the smart device 13, as described above. Therefore, it is assumed that the steps up to the work content of No. 10 in Figure 7 have been completed.

[0133] Next, the worker, following the instructions for step No. 11 in Figure 7, uses the camera function of the smart device 13 (a tablet in Figure 7) to scan the QR code attached to the supplementary section. A URL is then displayed on the screen of the smart device 13 (step S501 in Figure 10).

[0134] Next, the operator touches the URL displayed on the screen of the smart device 13, following the instructions for step No. 12 in Figure 7. The browser on the smart device 13 then launches, accesses the server 12 on the internet 15, and displays a web page on the screen of the smart device 13 (step S502 in Figure 10). At this time, since the QR code read above is an encoded string of a URL that uniquely accesses the web page dedicated to the NW device 81T, the web page displayed in step S502 in Figure 10 is the web page dedicated to the NW device 81T. Therefore, this web page dedicated to the NW device 81T displays text specific to the NW device 81T (in the example in Figure 10, "Initial files for Yokohama Station Rack:3 Shelf:2 will be installed").

[0135] Next, the worker confirms that the text written in the supplementary column to the side is displayed on the screen of the smart device 13, in accordance with the work procedure in No. 13 of Figure 7. This allows the worker to confirm that the correct process is executed on the NW device (NW device 81T) described in the work procedure in No. 9 of Figure 7.

[0136] Next, the operator presses the execute button on the web page displayed in step S502 of Figure 10, following the instructions for step No. 14 in Figure 7. Then, all subsequent command input operations to the NW device 81T are performed automatically without any operator intervention.

[0137] In practice, when the execution button on the web page displayed on the smart device 13 screen is pressed, the process associated with this execution button, namely the process of transferring a control instruction from the server 12 to the smart device 13, is initiated. Upon receiving the control instruction from the server 12, the smart device 13 automatically sends commands sequentially to the network device 81T according to the contents of the control instruction. The progress of the automatic command sending from the smart device 13 is displayed in real time on the web page on the smart device 13 screen (step S503 in Figure 10). Therefore, the operator can know the progress and completion of the automatic command sending. In this way, all control of maintenance and operation work for the network device 81T can be automated.

[0138] As described above, according to this embodiment 3, the command generator 11 receives work information, including the type of maintenance operation and the work parameters required for that maintenance operation. Based on the input work information, the command generator 11 generates a control instruction sheet containing information on the commands to be sent to the NW device 81T to be controlled and the order in which those commands should be sent, a web page for downloading the control instruction sheet, and a QR code that encodes the URL string for accessing the web page. The control instruction sheet and web page are stored on a server 12 on the internet 15, and the QR code is attached to the work procedure sheet. The smart device 13 is connected to the NW device 81T and enables the NW device 81T to access the internet 15. When the worker reads the QR code attached to the work procedure sheet using the camera function of the smart device 13, the URL is displayed on the screen. When the worker touches the URL, the smart device 13 accesses the server 12 and displays the web page on the screen. When the operator presses the execute button on the web page, a control instruction sheet is downloaded from the server 12 to the smart device 13. The smart device 13 then sequentially sends commands to the network device 81T according to the control instruction sheet.

[0139] Therefore, according to this embodiment 3, maintenance and operation work can be performed on the NW device 81T without connecting the NW device 81T to the DCN 83. Furthermore, maintenance and operation work can be performed on the NW device 81T as long as the smart device 13 has access to the internet 15. This reduces the constraints on the work location where maintenance and operation work can be performed. Furthermore, this third embodiment also provides the same effects as the first embodiment described above (the other effects 1 to 8 described above).

[0140] <Embodiment 4> <Image of Embodiment 4> First, let's describe the image of this fourth embodiment. Figure 21 is a diagram illustrating an example of maintenance and operation work for network equipment in this disclosure. In Figure 21, as in Figure 1, maintenance and operation work is performed to add a new network equipment 81T to the service network 82. Also in Figure 21, as in Figure 1, the multiple network equipment 81 constituting the service network 82 are connected to the DCN 83, and the control and monitoring system 84 is connected to the DCN 83.

[0141] As shown in Figure 21, the present disclosure provides a mechanism in which the smart device 13 holds control instructions for integrating the NW device 81T into the service NW 82. In other words, in this disclosure, the worker enters the station building with a smart device 13 containing control instructions. Then, the settings (S201) for integrating the NW device 81T into the service NW 82 are performed. As a result, maintenance and operation work on the NW device 81T can be performed even when the NW device 81T is not connected to DCN 83.

[0142] <Overview of Embodiment 4> Next, we will describe the outline of this fourth embodiment. The operation of this embodiment 4 can be broadly divided into two phases: the preparation phase shown in Figure 22 and the automated execution phase shown in Figure 23.

[0143] First, let's explain the operation of the preparation phase. Figure 22 illustrates an example of the operation of the preparation phase in this disclosure. As shown in Figure 22, in the preparation phase, the work plan manager, who is responsible for the maintenance and operation work, first inputs work information into the command generator 11, including the type of maintenance and operation work and the work parameters, which are the parameters required for that maintenance and operation work.

[0144] The command generator 11 generates control instructions and QR codes that conform to the input maintenance and operation tasks based on the input work information. These generated items are output for each network device to be controlled. In the following, it is assumed that the network device to be controlled is network device 81T.

[0145] The control instruction sheet is an electronic file containing information about the commands to be sent to the NW device 81T according to the entered maintenance and operation procedures, as well as the order in which those commands should be sent. The QR code is a two-dimensional code used to launch the application necessary for executing the control instruction sheet.

[0146] Before a worker enters a building such as a station or data center where the NW device 81T is installed (or where a new NW device 81T will be installed) and begins work, the control instructions are stored in the smart device 13, and the QR code is sent to the worker entering the work area. The QR code can be an electronic image or a printed document, but in Figure 22, it is shown as being printed on a paper work procedure manual brought by the worker.

[0147] Next, we will explain how the automated execution phase works. Figure 23 illustrates an example of the operation of the automated execution phase in this disclosure. As shown in Figure 23, the automation execution phase involves performing actual maintenance and operation tasks to which this disclosure applies.

[0148] First, the worker enters the building, such as a station or data center, where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing with them the work procedure manual with a QR code printed on it and the smart device 13.

[0149] Next, the worker directly connects the network device 81T and the smart device 13 according to the procedures outlined in the work procedure manual. This allows the network device 81T to access the smart device 13.

[0150] Furthermore, the worker proceeds with the maintenance and operation work according to the procedures outlined in the work procedure manual. During the procedure, when scanning a QR code, the worker scans the QR code printed on the work procedure manual using the camera function of the smart device 13. Then, the application launches on the screen of the smart device 13.

[0151] The operator confirms on the application screen that "commands will be automatically sent to the network device" and presses the execute button on the application screen. The smart device 13 then sequentially sends commands to the network device 81T according to the contents of the control instruction sheet. In other words, the smart device 13 sends the commands included in the control instruction sheet to the network device 81T according to the information on the order of input included in the control instruction sheet. This completes the maintenance and operation work. The fourth embodiment will now be described in detail.

[0152] <Details of Embodiment 4> First, the configuration of this fourth embodiment will be described. Figure 24 shows an example of the configuration of the maintenance and operation system 4 related to this disclosure. As shown in Figure 24, the maintenance operation system 4 includes a command generator 11 and a smart device 13. The following describes the individual components that make up the maintenance and operation system 4.

[0153] First, let's explain the command generator 11. As shown in Figure 6, each type of maintenance and operation work has its own set of work parameters. Therefore, when the work planner inputs work information into the command generator 11, they first input the type of maintenance and operation work, and then input the work parameters required for that work. For example, when the work planner inputs "New installation of NW equipment" as the type of maintenance and operation work, they input "Installation location," "Mounting position," "Equipment product name," "Manufacturer vendor," "Equipment name," "IP address," and "Config file" as work parameters. One method of inputting work information into the command generator 11 is to input it using the GUI. Another method is to write multiple maintenance and operation work tasks and the work parameters for each of these tasks into an electronic file in CSV format and import that electronic file into the command generator 11.

[0154] The command generator 11 generates and outputs two things based on the input work information: a control instruction sheet containing commands according to the work procedure of the input maintenance operation work and information on the order in which those commands should be issued, and a QR code for launching the application necessary to execute the control instruction sheet.

[0155] The control instructions generated by the command generator 11 are stored in the smart device 13. It is assumed that the control instructions are output directly from the command generator 11 to the smart device 13 via wireless or wired communication. However, this is not limited to this; the control instructions may also be output to another device and then output from that device to the smart device 13.

[0156] Meanwhile, the QR code generated by the command generator 11 is sent to the worker entering the work area. For example, the QR code is printed on the paper work procedure manual that the worker brings with them, as shown in Figure 22.

[0157] Figure 25 is a diagram illustrating an example of a work procedure manual related to this disclosure. As shown in Figure 25, the work procedure manual lists the tasks that the worker will perform on the day of work, in the order of the tasks. In the example in Figure 25, the QR code output from the command generator 11 is pasted in the supplementary column next to the task No. 11. Note that although Figure 22 shows the work procedure manual as being on paper, it may also be an electronic file.

[0158] Next, I will explain smart device 13. Smart devices 13 are general-purpose products such as smartphones and tablets that workers possess and carry with them for communication with relevant parties. The smart device 13 stores control instructions and sends commands to the network device 81T according to the control instructions. For example, the smart device 13 may incorporate general-purpose software that has the function of sequentially sending commands based on the contents of the control instructions.

[0159] Here, the connection protocol between the smart device 13 and the network device 81T, as well as the commands to be sent to the network device 81T and the order in which those commands are sent, may differ depending on the vendor and product specifications. However, all of these differences are absorbed within the control instruction document.

[0160] Figure 26 is a diagram illustrating an example of a method for connecting the smart device 13 according to this disclosure. As shown in Figure 26, in step S901, the network device 81T and the smart device 13 are connected. For example, the smart device 13 is physically connected to the management port 810 that controls the network device 81T using a cable specified by the manufacturer of the network device 81T (such as an Ethernet cable or a serial cable).

[0161] Furthermore, the smart device 13 is equipped with a camera function as standard. The camera function is used by the worker to read the QR code attached to the work procedure manual. When the QR code is read, the application is launched and the application screen is displayed. When the worker presses the execute button on the application screen, the smart device 13 sequentially sends commands to the NW device 81T according to the contents of the control instruction manual.

[0162] Next, the operation of this fourth embodiment will be described. First, let's explain the operation of the preparation phase. As shown in Figure 22, first, the work plan manager inputs work information into the command generator 11, including the type of maintenance operation work and the work parameters required for that maintenance operation work. The command generator 11 then generates a control instruction sheet and a QR code based on the input work information.

[0163] Here, we will explain in detail the operation of the command generator 11. Figure 27 is a diagram illustrating an example of the operation of the command generator 11 according to this disclosure. As shown in Figure 27, the command generator 11 generates a QR code and a control instruction sheet by performing conversions such as steps S1001, S1002, and S1003 on the input work information. At this time, the command generator 11 determines the application to be launched based on the information of the type of maintenance operation, installation location, and mounting position passed as work information, and generates a QR code specific to the NW device 81T as a code to launch the determined application. In addition, the command generator 11 generates a control instruction sheet specific to the NW device 81T, which is a string of unique commands based on the specifications of the device product, arranged in a unique input order, based on the information of the device product name, manufacturer, device name, IP address, and Config file passed as work information.

[0164] The control instructions generated by the command generator 11 are stored in the smart device 13. The QR code generated by the command generator 11 is also sent to the worker. For example, the QR code is printed in the supplementary section next to the relevant work procedure on the paper work procedure manual that the worker brings with them.

[0165] Next, we will explain how the automated execution phase works. As shown in Figure 23, first, the worker enters a building such as a central office or data center where the NW equipment 81T is installed (or where a new NW equipment 81T will be installed), bringing the work procedure manual and smart device 13 with them.

[0166] Next, the operator performs connection work to connect the network device 81T and the smart device 13. Once these connection tasks are completed, the smart device 13 will be able to access the network device 81T.

[0167] The subsequent steps will be explained using the installation of the new NW device 81T as an example, following the work procedure shown in Figure 25. Here, the worker has completed the connection work of connecting the NW device 81T and the smart device 13, as described above. Therefore, it is assumed that the steps up to the work content of No. 10 in Figure 25 have been completed.

[0168] Next, the worker, following the instructions for No. 11 in Figure 25, uses the camera function of smart device 13 (a tablet in Figure 25) to scan the QR code attached to the supplementary section. This launches an application on the screen of smart device 13. This is a web page specifically for NW device 81T. The QR code scanned at this time specifies the type of maintenance and operation work, installation location, and mounting position for NW device 81T. Therefore, the application screen displays text specific to NW device 81T (in the example in Figure 25, "Initial files for Yokohama Station Rack:3 Shelf:2 will be installed").

[0169] Next, the worker confirms that the text written in the supplementary column to the side is displayed on the application screen of the smart device 13, in accordance with the work procedure in No. 12 of Figure 25. This allows the worker to confirm that the correct process is executed on the NW device (NW device 81T) described in the work procedure in No. 9 of Figure 25.

[0170] Next, the operator presses the execute button on the application screen (corresponding to the execute button on the web page displayed in step S502 of Figure 10) according to the procedure in No. 13 of Figure 25. Then, all subsequent command input operations to the NW device 81T are performed automatically without any operator intervention.

[0171] In practice, when the execution button on the application screen of the smart device 13 is pressed, the process associated with this execution button is initiated, that is, the process by which the smart device 13 automatically sequentially sends commands to the network device 81T according to the contents of the control instruction sheet. The progress of the automatic command sending from the smart device 13 is displayed in real time on the application screen of the smart device 13 (corresponding to the web page screen displayed in step S503 of Figure 10). Therefore, the operator can know the progress and completion of the automatic command sending. In this way, all control of maintenance and operation work on the network device 81T can be automated.

[0172] As described above, according to this embodiment 4, the command generator 11 receives work information, including the type of maintenance operation and the work parameters required for that maintenance operation. Based on the input work information, the command generator 11 generates a control instruction sheet containing information on the commands to be sent to the NW device 81T to be controlled and the order in which those commands should be sent, and a QR code for launching the application required to execute the control instruction sheet. The control instruction sheet is stored in the smart device 13, and the QR code is attached to the work execution procedure sheet. The smart device 13 is connected to the NW device 81. When the operator reads the QR code attached to the work execution procedure sheet using the camera function of the smart device 13, the application is launched on the screen of the smart device 13. When the operator presses the execute button on the application screen, the smart device 13 sequentially sends commands to the NW device 81T according to the control instruction sheet.

[0173] Therefore, according to this embodiment 4, maintenance and operation work on the NW device 81T can be performed without connecting the NW device 81T to the DCN83. Furthermore, this fourth embodiment also provides the same effects as the first embodiment described above (the other effects 1 to 8 described above).

[0174] <Maintenance and operation procedures for embodiments 1-4> In the embodiments 1 to 4 described above, the maintenance and operation work was mainly explained using the work of adding a new NW device 81T as an example, but other maintenance and operation work can be handled in the same way. Examples of other maintenance and operation work will be described below.

[0175] Figure 28 illustrates an example of operation when performing a backup operation on NW device 81T1 in this disclosure. Figure 29 illustrates an example of operation when performing a restore operation on NW device 81T2 in this disclosure. Figures 28 and 29 assume that the backup and restore operations are performed by either maintenance and operation system 1 or 2.

[0176] As shown in Figure 28, if NW device 81T1 fails, the data from NW device 81T1 is saved as backup data in the control adapter 14. Also, as shown in Figure 29, once the replacement of the failed NW device 81T1 with NW device 81T2 is complete, the backup data stored in the control adapter 14 is sent to NW device 81T2 to restore NW device 81T2. Therefore, backup and restore operations can be performed as maintenance and operation work without connecting the controlled NW devices 81T1 and 81T2 to DCN83.

[0177] Note that while Figures 28 and 29 show backup data stored in the control adapter 14, this is not the only option. Backup data may also be stored in the smart device 13. In this case, the backup and restore operations shown in Figures 28 and 29 can be performed using any of the maintenance and operation systems 1 to 4.

[0178] Figure 30 illustrates an example of operation when performing data acquisition work on the NW device 81T in this disclosure. Note that Figure 30 assumes that the data acquisition work is performed by the maintenance and operation system 1.

[0179] As shown in Figure 30, the server 12 on the internet 15 collects data from the network device 81T via the control adapter 14 and smart device 13. Therefore, data collection can be performed as part of maintenance and operation work even without connecting the network device 81T to DCN83.

[0180] In Figure 30, server 12 collects data from network device 81T via control adapter 14 and smart device 13, but this is not the only way. Server 12 may also collect data via smart device 13. In this case, the data collection operation shown in Figure 30 can be implemented in either maintenance and operation system 1 or 3.

[0181] Figure 31 illustrates an example of operation when performing data acquisition work on the NW device 81T in this disclosure. Note that Figure 31 assumes that the data acquisition work is performed by either the maintenance and operation system 1 or 2.

[0182] As shown in Figure 31, the control adapter 14 collects data from the network device 81T. Therefore, data collection can be performed as part of maintenance and operation work even without connecting the network device 81T to be controlled to the DCN83.

[0183] In Figure 31, the control adapter 14 collects data from the network device 81T, but this is not the only way. The smart device 13 may also collect data directly from the network device 81T. In this case, the data collection operation shown in Figure 31 can be implemented in any of the maintenance and operation systems 1 to 4.

[0184] Figure 32 illustrates an example of operation when performing data upload work to the NW device 81T in this disclosure. Note that Figure 31 assumes that the data upload work is performed by the maintenance operation system 1. Furthermore, it is assumed that the control adapter 14 has already collected data from the NW device 81T.

[0185] As shown in Figure 32, the control adapter 14 uploads the data collected from the NW device 81T to the server 12 on the internet 15. Therefore, data upload operations can be performed as part of maintenance and operation work even without connecting the NW device 81T to DCN83.

[0186] In Figure 32, the control adapter 14 uploads data collected from the network device 81T to the server 12, but this is not the only option. The smart device 13 may upload data collected from the network device 81T directly or via the control adapter 14 to the server 12. In this case, the data upload operation shown in Figure 32 can be performed by either the maintenance and operation system 1 or 3.

[0187] <Embodiment 5> This fifth embodiment corresponds to an embodiment that expands upon the above-described embodiments 1 to 4. Figure 33 is a diagram showing an example configuration of the maintenance and operation system 5 related to this disclosure. As shown in Figure 33, the maintenance operation system 5 comprises a generation unit 21, a storage unit 22, and a input unit 23.

[0188] The generation unit 21 receives input of work information, including the type of maintenance operation and the work parameters required for that maintenance operation. Based on the work information, the generation unit 21 generates a control instruction sheet that includes information on the commands to be sent to the NW device to be controlled and the order in which those commands should be sent.

[0189] The storage unit 22 stores control instructions. The input unit 23 inputs commands to the controlled network device in the order in which the commands are input, based on the control instruction sheet.

[0190] Therefore, according to this embodiment 5, maintenance and operation work can be performed on the controlled network device without connecting the controlled network device to the DCN83.

[0191] The maintenance and operation system 5 may also include a smart device. In this case, the storage unit 22 may be a server on the internet. The input unit 23 may be a control adapter connected wirelessly or wired to the smart device and wired to the network device to be controlled. The generation unit 21 may also generate a web page for downloading control instructions. The server may also store the web page. The smart device may access the server on the internet using its wireless connection function and display the web page on its screen. The server may also transfer the control instructions to the control adapter via the smart device when a specific button on the web page displayed on the smart device's screen is pressed. The control adapter may also input commands to the network device to be controlled in the order they are entered, based on the control instructions. The generation unit 21 may also generate a two-dimensional code that encodes the URL for accessing the web page. Furthermore, the smart device may, when a QR code is scanned using its camera function, display a URL on its screen, and when the URL is touched, access a server on the internet using its wireless connectivity function to display a web page on the screen. The control adapter may also be portable.

[0192] Alternatively, the maintenance and operation system 5 may further include a smart device. In this case, the storage unit 22 and the input unit 23 may be a control adapter that is wirelessly or wiredly connected to the smart device and wiredly connected to the NW device to be controlled. The generation unit 21 may further generate a web page for executing the control instruction. The control adapter may further store the web page. The smart device may access the control adapter using its wireless connection function and display the web page on its screen. When a specific button on the web page displayed on the smart device's screen is pressed, the control adapter may input commands to the NW device to be controlled in the order of command input based on the control instruction. The generation unit 21 may further generate a two-dimensional code that encodes the URL for accessing the web page. When the two-dimensional code is read by the smart device using its camera function, the URL may be displayed on the screen, and when the URL is touched, the smart device may access the control adapter using its wireless connection function and display the web page on its screen. The control adapter may also be portable.

[0193] Alternatively, the storage unit 22 may be a server on the Internet. The input unit 23 may be a smart device connected via a wired connection to the NW device to be controlled. The generation unit 21 may further generate a web page for downloading the control instructions. The server may further store the web page. The smart device may access the server on the Internet using its wireless connection function and display the web page on its screen. The server may transfer the control instructions to the smart device when a specific button on the web page displayed on the smart device's screen is pressed. The smart device may also input commands to the NW device to be controlled in the order in which the commands are input, based on the control instructions. The generation unit 21 may further generate a two-dimensional code that encodes the URL for accessing the web page. The smart device may display the URL on its screen when the two-dimensional code is read using its camera function, and when the URL is touched, it may access the server on the Internet using its wireless connection function and display the web page on its screen.

[0194] Alternatively, the storage unit 22 and the input unit 23 may be smart devices connected via wire to the network device to be controlled. The generation unit 21 may also generate a two-dimensional code for launching an application necessary for executing the control instruction. Furthermore, when the two-dimensional code is read using the camera function of the smart device, the application may be launched, and when a specific button on the application screen is pressed, the commands may be sent to the network device to be controlled in the order in which the commands are entered, based on the control instruction.

[0195] Additionally, the two-dimensional code may be affixed to the work procedure manual that specifies the steps for maintenance and operation work. Furthermore, the work procedure manual may be on paper. In this case, the QR code may be attached to the work procedure manual as a printed document. Alternatively, the work procedure manual may be an electronic file. In this case, the QR code may be attached to the work procedure manual as an electronic image.

[0196] However, the configuration of this disclosure is not limited thereto. This disclosure may also include a receiving unit that receives input of work information including the type of maintenance operation and the work parameters required for the maintenance operation, and a generating unit that generates a control instruction sheet including information on commands to be sent to the network device to be controlled and the order in which those commands are sent, based on the work information.

[0197] <Hardware configuration of components constituting the maintenance and operation system> Figure 34 is a block diagram showing an example of the hardware configuration of a computer 90 that implements some or all of the functions of each component that constitutes the maintenance and operation systems 1 to 5 related to this disclosure.

[0198] As shown in Figure 34, the computer 90 includes a processor 91, memory 92, storage 93, input / output interface (I / F) 94, and communication interface (Communication I / F) 95. The processor 91, memory 92, storage 93, input / output interface 94, and communication interface 95 are connected to each other by data transmission paths for sending and receiving data.

[0199] The processor 91 is a processing unit such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The memory 92 is a type of memory such as RAM (Random Access Memory) or ROM (Read Only Memory). The storage 93 is a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or memory card. The storage 93 may also be a type of memory such as RAM or ROM.

[0200] A program is stored in the storage 93. This program includes a set of instructions (or software code) that, when loaded into a computer, causes the computer 90 to perform some or all of the functions of each component constituting the maintenance and operation systems 1 to 5. Some or all of the functions of each component constituting the maintenance and operation systems 1 to 5 may also be realized by the processor 91 loading and executing the program stored in the storage 93. Furthermore, the storage function in each component constituting the maintenance and operation systems 1 to 5 may be realized by memory 92 or storage 93.

[0201] Furthermore, the programs described above may be stored on non-temporary computer-readable media or tangible storage media. Examples, but not limited to, include RAM, ROM, flash memory, SSD or other memory technologies, CD (Compact Disc)-ROM, DVD (Digital Versatile Disc), Blu-ray® disc or other optical disc storage, magnetic cassettes, magnetic tapes, magnetic disk storage or other magnetic storage devices. The programs may also be transmitted over temporary computer-readable media or communication media. Examples, but not limited to, include electrical, optical, acoustic or other forms of propagating signals.

[0202] The input / output interface 94 is connected to a display device 941, an input device 942, a sound output device 943, and the like. The display device 941 is a device that displays a screen corresponding to the drawing data processed by the processor 91, such as an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube) display, or a monitor.
