- FIG. 10 is a flowchart showing the operation of the support system according to the present embodiment.
- the terminating device (CPE) 2 uses the connection monitoring unit 26 to monitor whether connection to the IP network 3 is possible and determines whether the communication state is normal (S501 and S501). S502). Specifically, it monitors whether the DHCP is functioning properly, whether the link is normally established, and whether the response status to PING is normal. If the communication state is normal ("N" in step S502), the monitoring of step S501 is continued periodically by loop processing.
- connection monitoring unit 26 sends a DHCPDISCOVER (if the client obtains an IP address or the like to the server V) from the PC1 by the connection monitoring unit. Is determined (S503).
- step S503 If there is no DHCPDISCOVER ("N” in step S503), the process returns to step S501 to continue monitoring. If there is a DHCPDISCOVER ("Y" in step S503), the DHCP server function of the access unit 23 issues a PrivateP request. Alternatively, if the connection with PC1 is a bridge connection, the connection is switched to a router to secure communication with PC1 (S504).
- step S505 it is determined whether there is an HTTP request (access to information data on the IP network 3) from the PC 1 (S505). If there is no HTTP request ("N" in step S505), the process is put into a standby state by loop processing. If there is an HTTP request ("Y" in step S505), the program execution unit 25 is started and the address replacement unit 22 is started. To redirect to the local support page (internal page) in the storage unit 24. Here, since the DHCP is not normal, the local support page to that effect is displayed.
- step S507 chat with a character for locale support.
- the program execution unit 25 analyzes a keyword in the text input to the text box 81 by the user, searches the storage unit 24 for a response related to the keyword, and outputs it. For example, for negative keywords such as "cannot connect”, text such as "apology” and “question” is output to identify the symptom, and possible causes and status reports related to this. I do. Here, the possibility of a router failure on the network side is reported, and a notification is sent that the support center is waiting for contact!
- talk log data The history of text data input and output by such a chat is recorded in the storage unit 24 as talk log data (S508).
- the recorded talk log data is connected to the server by dial-up, uploaded to the management server 41, and used for inference to determine the cause, and the inference result is reflected on the support page 8 or is supported. It is used as a material for manned support by the center.
- step S509 the user is prompted to select whether to click the button for calling server support displayed on the support page 8 or not. If the user does not request the server support ("N" in step S509), the process returns to step S507 to perform local support or end processing. On the other hand, if the user requests server support (“Y” in step S509), the user is redirected to the server support page 41a on the management server 41 by the address replacement unit 22, and dial-up is performed by the access unit 23. Start and connect to the management server 41 via PSTN4 (S601
- the management server 41 requests the input of a user ID and password and performs an authentication process before accessing the server support page 41a. (S602) o
- the customer information database 41c is checked. Identify users. If the authentication is successful, the server support page is transmitted, and the browser software 14a displays the server support page 41a (S603 and S511).
- an input section 82a having a check box for checking a diagnostic item and a text box for inputting other symptoms is displayed, and when a diagnosis start button 82b is pressed, the input section 82a is displayed.
- the input data is transmitted to the management server 41 as a customer request (S512 and S513).
- the management server 41 the inference processing in the runs (S604- S607) o specifically by inference application, the customer request (diagnosis item, symptoms) received user force to be based, database information to be acquired And device setting information (S604) .
- the customer information database 41c and the provisioning information database 41d are searched by the database information acquisition function from the MAC address and authentication information of the accessing user, Related data is obtained (S605).
- the setting information of each device on the communication path is collected through the communication network based on the diagnostic items analyzed by the request analysis function by the device setting information acquisition function.
- the rule definition file for the location and mode of the failure that has been identified based on the event, the identified failure is isolated, diagnosis for each isolated failure, and advice according to the solution (support information ) Is generated.
- the generated support information is reflected on the server support page 41a and displayed on the browser software 14a on one side of the user.
- the fault occurrence location and current status are reported as shown in Fig. 13.
- the program execution unit 25 on the CPE2 side inquires the user as to whether the problem has been solved (S515). If the problem is solved, the support is terminated. If the problem is not solved, the support is terminated. Request an operator connection (S516), connect to the operator (S608), and start manned support (S609 and S517).
- the terminal when a failure occurs in the communication line, the terminal is redirected to the local support page stored in the terminal device 2. Even in an environment where communication connection is not possible, necessary information such as maintenance information and support information can be delivered to the user.
- the management server 41 causes the server support page 41a to input a diagnosis item related to communication, and infers support information corresponding to the type of the input diagnosis item and a combination thereof. Since the information is distributed via a web browser, the information required to identify the location of the failure can be obtained by the user's input operation, which can contribute to improving the quality of support.
- log data of chats input / output to / from the support page 8 is recorded and transmitted to the management server 41, it is possible to listen to opinions from users in an interactive manner, etc. By collecting this on the management server, support can be enhanced.
- the AI call center function when a failure occurs, local or server support can be automatically provided by the AI call center function. Self-diagnosis is possible. As a result, it is possible to avoid delays in service due to troubles such as inability to communicate through telephone inquiries, and to eliminate unevenness in the quality of responses and advice due to differences in the level of experience of operators. it can. On the service provider side, on the other hand, the number of calls to the call center can be reduced, and the labor and equipment costs required for operating the call center can be reduced. Industrial potential
- a communication line such as the Internet is constructed by connecting to each other.
- an access device such as a modem or a terminal adapter accesses information data distributed on the IP network through the communication line, it is redirected to other information under the control of the service provider. It is possible to appropriately select the timing for executing the process and the target person, and it is possible to provide various services by performing redirection according to the form of the service.
