Description

The present invention relates to a network failure diagnosis result presentation apparatus that identifies a cause of a failure related to network connection and presents the diagnosis result to a user, a network failure diagnosis result presentation method, and a storage medium storing a program.

  In order to connect a personal computer to the Internet, it is necessary to set the personal computer. Then, when the personal computer cannot be set up well or when the connection failure cannot be dealt with, it is possible to inquire of the call center that provides the Internet service about the setting method or the connection failure. In addition, due to the increase in beginner users, inquiries to the call center are inundated regarding setting methods or connection failures.

  Therefore, a failure diagnosis tool is known in which the system automatically determines the cause of a failure and presents a countermeasure to the user when the Internet connection setting is not successful or when a connection failure occurs (for example, see Non-Patent Document 1). In this way, a failure diagnosis tool that promotes self-solution by the user has been proposed.

The failure diagnosis tool described in Non-Patent Document 1 is a type of tool that is installed and used on a client such as a personal computer terminal. When the presence of a failure is automatically detected, failure diagnosis is started, or when the user explicitly instructs the start of diagnosis, the diagnosis is started and the result of this diagnosis is presented on the screen of the personal computer.
Yoneyama Takahisa and Yoshihara Hiroto “User Interface Visualizing Wireless Networks” Toshiba Review, vol.59, no.11, pp.31-34, 2004

  However, in the above-described conventional example, failure diagnosis does not start when a failure that cannot be detected by the failure diagnosis tool occurs or when the user explicitly instructs the start of diagnosis.

  That is, there may be a failure that cannot be detected by the conventional failure diagnosis tool. For example, when a certain kind of security software is installed, a failure occurs in which it is not possible to connect to the Internet, but this failure may not be detected by a failure diagnosis tool.

  In the above conventional example, even if the failure diagnosis tool presents the diagnosis result on the personal computer screen, the user ignores the diagnosis result, makes a telephone inquiry to the call center of the product or service provider, and the call center There is a problem of being busy.

The present invention provides a network failure diagnosis result presentation device and a network failure diagnosis result presentation that can reduce inquiries to a call center when a failure that cannot be detected by the failure diagnosis tool occurs and a user calls the call center. It is an object of the present invention to provide a storage medium storing a method and a program.

The present invention relates to a diagnostic means for diagnosing the location of a cause of failure in a network, a specific number storage means for registering a specific number, and a telephone number transmitted to a specific number stored in the specific number storage means. A transmission detection means for detecting, a failure diagnosis start control means for causing the diagnosis means to start a network failure diagnosis when the call detection means detects a call to a specific number, and presents a network failure diagnosis result by the diagnosis means And a network failure diagnosis result presentation device having a diagnosis result presentation means.

According to the present invention, when a failure that cannot be detected by the failure diagnosis tool occurs and the user calls the call center, the inquiries to the call center can be reduced.

  The best mode for carrying out the invention is the following examples.

  FIG. 1 is a system configuration diagram illustrating a network failure diagnosis result presentation apparatus 100 that is Embodiment 1 of the present invention.

  When a failure that cannot be detected by the failure diagnosis tool occurs and the user calls the call center, the network failure diagnosis result presentation device 100 starts the failure diagnosis without connecting to the call center, and displays the diagnosis result.

  The call destination storage unit 210 stores the call destination telephone number of the telephone T0 as shown in FIG. When not in a call, the callee storage unit 210 stores a specific symbol such as “null” so that it can be understood that the call is not in progress.

  The specific number transmission detection unit 300 includes a transmission detection unit 310, a specific number inspection unit 320, and a specific number DB 330.

  The transmission detection unit 310 monitors the call destination storage unit 210 and detects that the telephone set T0 has transmitted. That is, when the symbol indicating the state of the call destination stored in the storage unit 210 changes from a symbol indicating that a call is not in progress to an arbitrary phone number, it detects that the telephone set T0 has transmitted. When the transmission is detected, the fact that the transmission has been detected and the destination number are transmitted to the specific number inspection unit 320.

  The specific number inspection unit 320 determines whether or not the call destination number received from the call detection unit 310 exists in the specific number DB 330, and the call destination number received from the call detection unit 310 exists in the specific number DB 330. If it is determined that there is, a diagnosis request is output to the failure diagnosis unit 400.

  FIG. 3 is a diagram illustrating an example of specific numbers registered in the specific number DB 330.

  The specific number DB 330 registers a telephone number that the user is supposed to inquire in the event of a network failure, such as a call center telephone number, as shown in FIG. 3, and answers the reference request from the specific number inspection unit 320. .

  The failure diagnosis unit 400 includes a diagnosis result storage unit 410 and a diagnosis execution unit 420.

The specific number DB 330 is an example of specific number storage means for registering a specific number. The transmission detection unit 310 is an example of a transmission detection unit that detects that a telephone connected to the apparatus has made a call to a specific number stored in the specific number storage unit. The diagnosis execution unit 420 is an example of a failure diagnosis start control unit that causes the diagnosis unit to start a network failure diagnosis when the transmission detection unit detects a transmission to a specific number. The display unit D0 is an example of a display unit that displays a network failure diagnosis result obtained as a result of failure diagnosis by the diagnosis execution unit on a screen.

  Next, the operation of the network failure diagnosis result presentation apparatus 100 will be described.

  FIG. 5 is a flowchart showing the operation of the network failure diagnosis result presentation apparatus 100.

  The call detection unit 310 monitors the call destination storage unit 210 and determines that a call has been detected when the content stored in the call destination changes from a symbol indicating that the call is not in progress to an arbitrary phone number ( Go to S1) and S2.

  If the specific number search unit 320 determines whether or not the call destination number received from the call detection unit 310 exists in the specific number DB 330 (S2), and determines that the received call destination number exists in the specific number DB 330. , Go to S3.

  The diagnosis execution unit 420 diagnoses the cause of the failure of the network that is the diagnosis target of the network failure diagnosis result presentation device 100, and writes the diagnosis result ID for specifying the diagnosis result in the diagnosis result storage unit 410 (S3).

  According to the first embodiment, when a failure occurs in which the failure diagnosis tool cannot detect the presence or when the user ignores the diagnosis result displayed on the PC display, when the user calls the call center, the diagnosis result depends on the diagnosis result. In addition, the user can be guided to solve the failure. Therefore, self-solving by the user can be supported, and the number of inquiries to the call center can be reduced.

  Actually, if a failure occurs that cannot be detected by the failure diagnosis tool, or if the user ignores the diagnosis result displayed on the PC display, when the user calls the call center, whether the call center is talking If there is an announcement tape such as "Please wait for a while" on the other hand, if there is an announcement tape such as "Please wait a little" 100 performs failure diagnosis and displays the failure diagnosis result on the display unit D0.

  The display unit D0 is an example of a diagnosis result presentation unit that presents a network failure diagnosis result by the diagnosis unit.

  Even when a failure cannot be found at the time of failure, a normal location can be identified. Therefore, there should be a failure in a location other than the location where it has been confirmed that it is normal, the cause of the failure can be narrowed down, which is much more useful than when there is no failure information.

The network failure diagnosis result presentation device 100 may only diagnose the cause, may present the countermeasure after diagnosing the cause, and may present the diagnosis result.
