  Hereinafter, a network device maintenance system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment. Here, the local network is a home network provided at home, and the public wireless communication network is assumed to use a mobile phone communication network. The network equipment maintenance system includes a maintenance information terminal 100, a mobile phone communication network 200, the Internet 300, a maintenance management server 400, a wide area network (WAN) 500, and a circuit termination device (DCE). -terminating equipment) 600, a home network 700, a home network management device 800, a wireless LAN access point 900 that is a maintenance target, and a wireless LAN terminal 1000 that is also a maintenance target.

  The maintenance information terminal 100 includes a control unit 101, a mobile phone communication unit 102, an information display unit 103, a program processing unit 104, an operation unit 105, and a wireless LAN communication unit 106. The maintenance management server 400 includes a control unit 401, a maintenance information database 402, a program database 403, and a home network identification verification unit 404. The home network management apparatus includes a control unit 801, a home network management database 802, a program processing unit 803, and a home network connection authentication unit 804.

  The same applies when an office network is used as the local network and another public high-speed data communication network is used as the public wireless communication network.

  Next, the control operation of the network equipment maintenance system shown in FIG. 1 will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the network equipment maintenance system shown in FIG. First, the maintenance information terminal 100 acquires a maintenance information terminal program from the maintenance management server 400 (step S1), establishes execution of the maintenance program and connection with the home network (HNW) management device 800 (step S2), and home The network management device 800 is instructed to start maintenance work (step S3). In response to this, the home network management device 800 acquires a home network management device program from the program database 403 of the maintenance management server 400 in accordance with an instruction from the maintenance information terminal 100 (step S4), and executes the maintenance program to perform maintenance. The result is notified to the information terminal 100 (step S5). The maintenance information terminal 100 displays the maintenance work result on the information display unit 103 according to the notification result from the home network management apparatus 800 (step S6), and the worker confirms the display result.

  Next, the operation of the system shown in FIG. 1 will be described with a specific example. 3 and 4 are flowcharts showing the operation of the system shown in FIG. In the operation shown in FIG. 3 and FIG. 4 (showing the operation continued from FIG. 3), the case where the wireless LAN terminal 1000 becomes unable to connect to the wireless LAN access point 900 is taken as an example based on the control operation shown in FIG. The operation in the case of performing the maintenance work of “identifying the defective part” will be described. From the event of a wireless LAN connection failure alone, it is not known whether there is a failure on the wireless LAN access point 900 side or a failure on the wireless LAN terminal 1000 side. Therefore, the side of the problem is specified, and if the device setting is the cause of the problem and the problem can be solved automatically, the control operation for restoring the wireless LAN connection will be described.

  First, the maintenance information terminal 100 downloads the maintenance information terminal program software from the maintenance management server 400 (program database 403) (step S1-1), and activates the maintenance information terminal program software to establish a wireless LAN access point. It connects to 900 (step S2-1). Here, since the maintenance information terminal 100 includes the program processing unit 104, the program software can be easily executed.

  If the connection to the wireless LAN access point 900 (step S2-2) is successful (Yes), the connection to the home network management device 800 is established via the wireless LAN access point 900 (step S2-3). On the other hand, if the connection is not successful due to a device failure or device setting failure of the wireless LAN access point 900, authentication information such as SSID or encryption information for connection to the base station is unknown, etc. (No ) A connection to the home network management device 800 on the home network 700 is established via the mobile phone communication network 200, the Internet 300, and the wide area access network 500 (step S2-4).

  At this time, for example, information for the operator to identify the home network 700 and authentication information for permitting execution of the maintenance work via the maintenance management server 400 are input to the maintenance information terminal 100 or the network management authority is granted. Authentication for performing maintenance work in the home network 700 is performed by connecting a hardware key to be authenticated to the maintenance information terminal 100. If the control unit 401 of the maintenance management server 400 and the control unit 801 of the home network management device 800 mutually implement a remote management protocol such as CWMP (Customer Premises Equipment WAN Management Protocol), the maintenance management server 400 further A connection to the home network management device 800 can be established. As a result, the home network identification information and authentication information are sent from the control unit 101 of the maintenance information terminal 100 via the control unit 401 of the maintenance management server 400 and the control unit 801 of the home network management apparatus 800. Forwarded to 804. By executing the maintenance work authentication process in the home network connection authentication unit 804, the connection between the maintenance information terminal 100 and the home network management apparatus 800 is established, and the maintenance work can be performed via the public wireless communication network. Become.

  Next, after the connection with the home network management apparatus 800 is established, the maintenance information terminal 100 instructs the home network management apparatus 800 to start the “identify faulty part” function and start the actual maintenance work ( Step S3-1). In response to this, the home network management device 800 downloads home network diagnostic program software from the program database 403 of the maintenance management server 400 based on the instruction of the maintenance information terminal 100 in step S3-1 (step S4-1). The home network diagnostic program software is activated to search for the wireless LAN access point 900 installed in the home network 700 (step S5-1). Here, since home network management apparatus 800 includes program processing unit 803, the program software can be easily executed.

  If the search for the wireless LAN access point 900 (step S5-2) is not successful (No), the home network management device 800 determines that the problem is difficult to solve further, and the wireless LAN access point 900 The maintenance information terminal 100 is notified of a connection failure or failure on the side. The maintenance information terminal 100 displays a physical connection failure or failure such as a wiring mistake on the wireless LAN access point 900 side on the information display unit 103 (step S6-1), and notifies the operator of this information. To do.

  On the other hand, when the search for the wireless LAN access point 900 is successful (Yes), the user logs in to the maintenance management manager operating in the wireless LAN access point 900 based on the information registered in the home network management database 802. (Step S5-3), information on connection terminals under the wireless LAN network, wireless LAN access point setting information, and the like are collected (Step S5-4).

  At this time, authentication information and the like for logging in to the wireless LAN access point 900 is registered in advance in the home network management database 802 when the wireless LAN access point 900 is installed, so that an operator requests information input during maintenance work. It will never be done. Of course, since the maintenance information terminal 100 includes the operation unit 105, the operator can appropriately input necessary information. It is possible to automatically log in to a maintenance management application inside the wireless LAN access point 900 and collect the wireless LAN network information.

  Next, the home network management device 800 checks whether or not the maintenance information terminal 100 is normally connected to the wireless LAN access point (step S5-5). When the connection between the maintenance information terminal 100 and the wireless LAN access point 900 has not been established (No (in the case of passing through step S2-4)), maintenance work and maintenance information for the wireless LAN access point 900 by the maintenance information terminal The terminal 100 is registered (step S5-6), and the connection with the maintenance information terminal 100 is switched via the wireless LAN access point 900 (step S5-7).

  If authentication information such as SSID or encryption information for connection to the base station is required, it can be distributed from the home network management device 800 to the maintenance information terminal 100 via the mobile phone communication network 200. is there. If the connection between the maintenance information terminal 100 and the wireless LAN access point 900 has been established (Yes), the process may go directly to step S5-8.

  Next, when it is confirmed that the connection between the maintenance information terminal 100 and the wireless LAN access point 900 has been established, the trouble solving procedure on the wireless LAN terminal 1000 side is downloaded from the maintenance information database 401 of the maintenance management server 400 (step S5-8), the problem solving procedure is executed (step S5-9). Here, since the maintenance information terminal 100 includes the wireless LAN communication unit 106, as an example of a problem solving procedure, maintenance work such as further attempting an ad hoc connection with the wireless LAN terminal 1000 is subsequently performed. You can also Even during the maintenance work, it is possible to make an inquiry to the maintenance management server 400 as needed, or to ask the worker to input information via the maintenance information terminal 100.

  After performing the problem solving procedure, it is confirmed whether or not the connection from the wireless LAN access point 900 to the wireless LAN terminal 1000 has been restored (step S5-10). If the wireless LAN connection has not been restored (No) ), The home network management device 800 determines that the problem is difficult to solve any more, and notifies the maintenance information terminal 100 of a physical connection failure or failure such as a wiring error on the wireless LAN terminal 1000 side. To do. The maintenance information terminal 100 displays on the information display unit 103 that there is a connection failure or failure on the wireless LAN terminal 1000 side (step S6-2) and notifies the operator of this information.

  Alternatively, when the wireless LAN connection is restored in step S5-10 (Yes), the home network management device 800 notifies the maintenance information terminal 100 that the problem of the wireless LAN connection has been solved. The maintenance information terminal 100 displays on the information display unit 103 that the problem of the wireless LAN connection has been resolved (step S6-3), and notifies the operator of this information.

  In the above description, the case where the “defect location” function is performed as a maintenance work when a wireless LAN connection failure occurs is described as an example. Similarly, the “initial installation of network device” function can be realized by applying the control operation shown in FIG. In addition, by applying the control operation shown in FIG. 2, it becomes possible to automate maintenance work of various network devices regardless of whether the network device is a wireless device or a wired device.

  As described above, the maintenance information terminal 100, which is carried by a maintenance worker who performs maintenance work on the network device and has the function of connecting to the mobile phone communication network 200 and the function of displaying information to the worker, In a network equipment maintenance system comprising a maintenance management server 400 that is connected via a mobile phone communication network 200 and the Internet 300 and has a function of providing maintenance-related information necessary for maintenance work to the maintenance information terminal 100 , Home network management apparatus 800 having a function of database management of maintenance setting information of network devices connected to home network 700, and a function of executing software for maintenance work of network devices, home network management apparatus 800 and maintenance management server 400 to connect to the network The maintenance management server 400 provides maintenance program software for executing maintenance work on the home network management device 800 to the home network management device 800 so that the home network management device 800 can perform maintenance work on network devices. Can be automated.

  Also, the maintenance information terminal 100 instructs the home network management device 800 to perform maintenance work on the network device, and the home network management device 800 performs maintenance from the maintenance information terminal 100 notified via the maintenance management server 400. Software that performs maintenance work in response to the work instruction is executed, the maintenance work result is returned to the maintenance information terminal 100, the maintenance information terminal 100 displays the response result, and the maintenance worker uses the maintenance information terminal 100 to It is possible to instruct the network management device 800 to execute maintenance work, and similarly to notify the maintenance worker of the maintenance work execution result using the maintenance information terminal 100.

  Also, the maintenance information terminal 100 executes software for performing maintenance work execution instructions and maintenance work execution result notifications, and the maintenance management server 400 provides maintenance program software for instructing maintenance work from the maintenance information terminal 100. 100. A general-purpose portable electronic device such as a smartphone or a tablet terminal that can execute the maintenance work execution instruction and the maintenance work execution result notification in software can be used as the maintenance information terminal 100.

  Further, the maintenance management server 400 has a function of providing a connection to a local network (home network 700) to which a network device is connected based on the local network identification information input from the maintenance information terminal 100, and a home network management device 800 has a function of controlling the connection between the maintenance information terminal 100 and the home network management apparatus 800 based on the local network identification information, and the maintenance managed by the home network management apparatus 800 in the database using the maintenance information terminal 100 It is possible to browse the setting information or perform maintenance work of the network device using the maintenance setting information.

  Further, the maintenance information terminal 100 acquires the maintenance information terminal program software, executes the maintenance information terminal program software, establishes a connection with the home network management apparatus 800, and performs maintenance work on the home network management apparatus 800. The home network management device 800 acquires home network management device program software based on an instruction from the maintenance information terminal 100, executes the maintenance program software, and executes maintenance work on the maintenance information terminal 100. The maintenance information terminal 100 notifies the operator of the execution result notified from the home network management apparatus 800 by notifying the result, and the maintenance work of the network device can be automated.

  As described above, according to the system shown in FIG. 1, maintenance software programs are downloaded to the program processing unit 104 of the maintenance information terminal 100 and the program processing unit 803 of the local network management device 800, respectively. Therefore, the actual maintenance work can be automated, and the actual maintenance work burden on the worker can be reduced. In addition, maintenance work time can be shortened.

  Moreover, regarding the functional configuration that the maintenance information terminal 100 should have, it can be easily realized by combining program software processing with a smartphone, a tablet terminal, or the like that has been rapidly spreading for general users in recent years. Therefore, if a general user installs a network management device (for example, home network management device 800) in a local network (for example, home network 700) and contracts with a maintenance service provider having the maintenance management server 400, You can become a worker and perform maintenance work. As a result, it is possible to omit the costly dispatch of skilled maintenance workers and the like, and it is possible to perform maintenance work of network devices quickly and efficiently at a low cost.

  In addition, since an information terminal such as a smart phone or a tablet terminal on hand can be used as the maintenance information terminal 100, the user who is the installer constructs and uses the maintenance system from the time when a network device is newly installed in the local network. be able to. At this time, the system can be operated so that setting information and the like are simultaneously registered in a network management apparatus (for example, home network management apparatus 800) at the time of device installation. As a result, the home network management information can be managed in a unified manner, and when a malfunction of the network device occurs, the operator can quickly solve the problem.

  In the conventional network maintenance method, it is general that a worker is dispatched to a network where a failure has occurred and checks whether or not each device has a failure. This method requires workers to have a certain level of knowledge about network equipment and communication technology. Also, in a private network, authentication information required for connection may not be obtained, which reduces work efficiency. There is. In response to this, failure detection is performed using a wireless maintenance terminal operated by a worker and a management device connected to the maintenance target network. Specifically, the wireless maintenance terminal is provided with two or more wireless interfaces, and when the first wireless interface tries to connect to the maintenance target wireless communication device and the connection is successful, this communication line is used. To cause the management device to detect the fault location. On the other hand, when the connection fails, the management apparatus is accessed using the second wireless interface (for example, a mobile phone interface), and the failure part is detected. In this way, when it is not possible to directly connect to one wireless communication device, it is possible to always access the management apparatus by bypassing the other wireless line. In addition, when the other wireless line is detoured and connected, the wireless maintenance terminal can be connected to the wireless communication device by setting the management device so that the failure of the wireless communication device can be recovered or the wireless maintenance terminal can be connected. It becomes like this. In addition, after the wireless maintenance terminal is connected to the wireless communication device, the wireless maintenance terminal tries to connect to another wireless communication device connected to the network. With this configuration, it is possible to easily detect and recover from a maintenance target network and to recover communication between wireless stations that could not communicate with each other.
