Abstract

PURPOSE:To attain the real-time monitor and to secure the maximum traffic understanding capacity by using the stored data to produce and display the data used for maintenance and control of the service quality. CONSTITUTION:Data collectors 2-1-2-n collect data from communication network forming devices 1-1-1-n and then transfer them to centers 3-1-3-m after storage and conversion. Then the centers 3-1-3-m send the data collected by the collectors 2-1-2-n to a data base device 8 directly or via a data transmission network 11. The device 8 sorts the received data and converts them into a desired form by data processors 9-1-9-q after conversion of type. These converted data are transmitted. The processors 9-1-9-q use these data to perform the calculation of the number of equipments and various types of statistic processing for maintain and control of the quality of a communication network.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a communication network management/control system, and in particular to a switching system,
Transmission line 1 Automatically collects and stores online the data (traffic data, etc.) necessary for the maintenance and operation of the communication network consisting of communication processing equipment, etc., monitors and controls the communication network, and furthermore designs equipment. Communication network management/control that comprehensively manages and controls communication networks by providing data used for communication as needed.
How to control.

It is related to the formula.

[Prior art]

Conventionally, communication network monitoring and control, for example, involves collecting and displaying limited data for monitoring switching equipment online, and using the displayed information, network managers can grasp the congestion status of the communication network and take regulatory measures. If this was determined to be the case, this was accomplished by instructing switch maintenance personnel to control the switch. moreover,
In particular, for congestion in specific areas with a high frequency of congestion and congestion for specific subscribers, data for detecting congestion is collected online from the communication network, and when congestion is detected, the communication network is controlled to prevent the spread of congestion. The traffic control system that avoids this was dealt with. (Refer to the literature ``Telephone network traffic control - Operations Research 19 s 4.'', March issue) In addition, regarding the collection and processing of data used for equipment design, etc. Data accumulated by each device or an observation device attached externally to each device is transferred to magnetic tape by manually inputting commands to each device.

This was accomplished by manually collecting data on a communication network scale by outputting it on paper tape, etc., and inputting it into an offline processing computer that executes equipment design, etc. In this way, conventional manual monitoring of communication networks In control,
It is necessary to anticipate congestion patterns of all kinds of communication networks in advance and consider countermeasures to deal with them.This requires a huge amount of work, and the utilization rate of countermeasures is low.

Furthermore, there is a lack of promptness in taking measures. In addition, traffic control systems that automate the monitoring and control of communication networks,
It is not possible to adequately evaluate the effectiveness of the control because it can only respond to specific congestion patterns and cannot grasp the operating state of the entire communication network when traffic control is in effect.

In the manual collection of data used for equipment design, etc.
In order to reduce the amount of collection work as much as possible, we limited the collected data and sampled the collection days.
This method had the disadvantage that it could not be reflected sufficiently in traffic forecasts, and it was not possible to fully understand regionally specific traffic characteristics.

[Purpose of the invention]
