Abstract

PURPOSE:To suppress the transmission of fault information from a user whose monitoring is unnecessary by making it unnecessary to send information from a user terminal during a period except the time of operation between operation start time and operation end time even when the user terminal sets up a communication bus capable of having input access. CONSTITUTION:A time band allowed to drive a user's terminal 1 is strictly specified from a certain time up to another fixed time every day. Prior to the start of system operation, the terminal 1 registers user information in a packet exchange 22 in a network 2. The exchange 22 sets up the state of 'within or out of operation time' and controls the set state by the information of 'operation start time' and 'operation end time'. At the time of detecting a fault, the state of 'within or out of the operation time' is judged, and in the case of the state of 'out of the operation time', fault information is not outputted. If within the operation time, user's fault information is outputted only when a communication bus state is set up. Thereby only original fault/fault recovery generated within the time band to be operated can be monitored and redundant information can be excluded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user fault monitoring control system, and more particularly to a network including a packet switch, user terminals connected to this network, and network management for monitoring these networks and user terminals. The present invention relates to a user fault monitoring control method for performing control to eliminate redundancy in fault monitoring for a user terminal of a large-scale system including a center.

[0002]

2. Description of the Related Art A conventional large-scale system of this type is, for example, a cash dispenser system of a bank. A user uses a cash dispenser as a user terminal to perform deposit / withdrawal processing, and a network having a packet switch performs input / output of each user terminal using packet processing. The entire system is placed under the control of the network management center, and the failure monitoring of the user terminal is performed based on the setting of the user failure monitoring state by the packet switch.

The packet switch has a function of constantly monitoring and detecting a failure of a user terminal. However, this function is regarded as failure detection even if the power is simply cut off on the user terminal side. A failure of the user terminal including this kind of failure is notified to the network management center as a user failure notification. The maintainer of the network management center is supposed to deal with the user terminal targeted for the fault notification. Therefore, if a failure detection / recovery detection by simply turning on / off the power of the user terminal is notified to the network management center as a notification, the maintenance person cannot handle it. Against such a background, it has become necessary to devise such that the failure notification of the user terminal is notified only when the user terminal is actually operating and performing a service.

Conventionally, the time zone in which the user terminal operates and provides services has been the time zone in which the communication path for the user terminal is set. Therefore, the "user failure monitoring state" set by the packet switch is such that the state in which the communication path is set is "monitoring" and the state in which the communication path is disconnected is "non-monitoring". Are doing. By this control, the failure detected on the packet switch side is unconditionally notified to the network management center as a failure notification if the communication path is set at that time.

[0005]

In this conventional user fault monitoring control system, whether or not the fault monitoring state is determined is based only on the presence or absence of the setting state of the communication path in the packet switch. However, in actual operation, the power of the user terminal may be turned on later than when the communication path is set. In addition, the power of the user at the end of the service may be turned off before the communication path is turned off. Therefore, “communication path setting time = user operating time” is not always satisfied. For this reason, there is a problem in that determining the fault monitoring state based only on the communication path setting state causes a fault notification of a user who does not need monitoring to be output.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a user failure monitoring control method that suppresses the output of failure notifications of users who do not need monitoring.

[0007]

A system of the present invention is a network including a packet switch, a user terminal connected to the network, and a network management center for monitoring the network and the user terminal. A user failure monitoring control method for monitoring a failure of the user terminal in a large-scale system that provides a predetermined service in response to a user request input from the user terminal, the network comprising: When the packet switch detects a failure of the user terminal, it notifies the network management center of this as a failure notification and sets the user failure monitoring state to perform failure monitoring. Input access is possible for the user terminal outside the operating hours between the operation start time and operation end time registered in the exchange. Even if the communication path is being set, it is not necessary to generate the failure notification due to a difference between the timing of setting and disconnecting the communication path for the user terminal and the timing of turning on and off the power of the user terminal. It has a configuration to suppress.

Further, in the system of the present invention, the packet switch is used for the two states of the user terminal, that is, the operating time and the operating time, based on the operation start time, the operation end time, and the current time. The packet switch is configured to be set for each personal terminal, and the packet switch autonomously performs control such that the failure monitoring state is set to non-monitoring even during the communication path setting outside the operating time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
In this embodiment, a cash dispenser system of a bank is taken as an example of a large-scale system, and a user terminal 1 having a plurality of cash dispensers 11, 12, ..., 1n, a network 2 including a packet switch 22, a network management center 3 Equipped with. The network 2 detects a failure of each cash dispenser of the user terminal 1 and notifies the network management center 3 of the packet switch 22.
And a telephone network or a leased line network that connects the user terminal 1 and the packet switch 22, the telephone network 21 in this embodiment.
And a data processing unit 23 that processes the data packet-processed by the packet switch 2.

FIG. 2 is an explanatory diagram of an operating state of the embodiment shown in FIG. The operation of this embodiment will be described below with reference to FIG.

Conventionally, the communication path state 101, which indicates whether or not the communication path that makes the user terminal 1 accessible to the network 2, is set, corresponds to the user failure monitoring state 103 as it is. That is, communication path status 101
In the setting of, the packet switch 22 sets the user failure monitoring state 1
03 is "monitoring" and the user failure monitoring state 103 is "stopped" when the communication path status 101 is not set.
The user terminal 1 normally performs power-on 106 immediately before the time zone in which it should operate and power-off 109 immediately after the time zone in which it should operate. On the other hand, the communication path state 101 is also "set" immediately before the operating time zone and "non-set" immediately thereafter. The problem here is that the power-on / off of the user terminal 1 and the setting / cut-off of the communication path are not always synchronized, and the power-on of the user terminal 1 106
May be after the trigger for setting the communication path state 101. In addition, power off 109 of the user terminal 1
May occur before the trigger of non-setting (disconnection) of the communication path state 101. From the viewpoint of the maintenance person, these power-on 1
The output of the notification by 06 / power off 109 is not required. What the maintenance person needs is the output of the notification regarding the failure occurrence 107 and the failure recovery 108 in the time zone in which the user should operate. In the conventional method, it is not possible to perform control to output only the notification required by the maintenance personnel, and a failure occurs 10
7. In addition to fault recovery 108, power on of user terminal 1 1
In the case of 06 and power off 109, a notification is output.
The present invention improves the redundancy of this unwanted notification.

The time zone in which the user terminal 1 should operate is strictly specified every day from a fixed time to a fixed time. The user terminal 1 is connected to the network 2 before the system starts operation.
The user information is registered in the packet switch 22. The registration of the user information is registration of information on the “operation start time” and the “operation end time” for each cash dispenser. The packet switch sets the in / out time state 102. This state management is controlled by the information of "operation start time" and "operation end time". Control that causes the packet switch 22 to autonomously make a state transition every day, such as “outside operating hours” → “inside operating hours” at the start time of the user terminal 1 and “inside operating hours” → “outside operating hours” at the operating end time. I do.
When a failure is detected, the inside / outside operating state 102 is determined. If it is outside the operating hours, the failure notification is not output. If it is within the operating time, the communication path status 101 is determined. Only when this judgment is set, the user failure notification is output. That is, the user failure monitoring state 103 is "monitoring"
Only when the communication path state 101 is “set” and the in-operation time / outside state 102 is “in operation time”, all other states are “stopped”. In this way, the user failure monitoring state 103 at the time of turning on the power supply 106 is "stopped" and no notification is output. Also, at the time of power-off 109, similarly, the status is "stopped" and no notification is output. The notification is output only in the case of failure occurrence 107 and failure recovery 108. Therefore, it is possible to monitor only the original failure / failure recovery that occurs within the operating time zone, and it is possible to eliminate redundant notification.

FIG. 3 is a flow chart of the operation of the present invention. When a user failure detection indicating a malfunction of the user terminal 1 is performed (step 201), it is determined whether the failure detection is within the operating time (step 202), and if YES, the communication path state 101 is set. It is judged whether it is set or not (step 203), and if NO, no failure notification is output (step 204). The judgment in step 203 is Y
If it is ES, a fault report output is issued (step 20).
5) If NO, no fault report output is made (step 206). The packet switch 22 determines whether or not to output the fault notification, and when the fault notification is output, it is sent to the network management center 3.

In this way, unnecessary failure notification can be fundamentally suppressed.

[0016]

As described above, according to the present invention, a network including a packet switch, a user terminal connected to the network, and a network management center for monitoring the whole are input from the user terminal. When a failure of a user terminal in a large-scale system that provides services in response to a user's request is detected and the network side notifies the network management center of the failure, In addition, by setting two states, "within operation time" and "outside operation time", and performing user failure monitoring control only during "operation time", only the necessary failure notification is output and failure monitoring is not required. This has the effect of suppressing trouble reports and significantly reducing the maintenance work of maintenance personnel.
