Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information transfer method between a congestion detection device and a regulation control device.

Conventionally, equipment such as switched lines that make up telephone networks has been designed to be able to carry a certain amount of telephone traffic.

Therefore, if traffic locally exceeds a certain level due to social factors or the like, causing a state of congestion, the telephone network will be disrupted, the rate at which telephone connections can be made will deteriorate, and this will cause problems in social life.

Conventionally, there are methods for detecting the above-mentioned confusion, or in other words, abnormal failures, and taking appropriate measures for the entire telephone network.

According to this system, the exchanges (offices) that make up the network.

Then, the overload of the common device is detected and sent to the network management device.

The network management device judges the detected situation, decides on the corrective action to be taken, gives appropriate instructions to surrounding stations and lines, and takes manual or automatic action to deal with the abnormal failure.

Figure 1 is a simplified diagram of the information transfer method used to monitor and detect abnormal failures such as light chain conditions in the conventional telephone network. The device is a so-called congestion detection device, and the SRT transmits and receives the measurement results from the congestion detection device NTU to and from a regulation control device (described later) that constitutes a network management device via a dedicated line that connects the two. It is a signal transmission and reception trunk.

C0NT is a regulation control device that aggregates and analyzes measurement results received from multiple exchanges to determine the status of each exchange.

In the above configuration, the light chain detection device NTU constantly measures and monitors the efficiency of the common device of the exchange, and periodically sends a signal to the regulation control device C0 via the signal transmission/reception device SRT and the dedicated line.
The measurement results are transferred to NT.

Therefore, the regulation control device C0NT aggregates the above measurement results transferred from multiple exchanges according to a certain period, analyzes it, makes a situational judgment, and when a light chain state is detected, decides on the treatment for it and makes an incidental decision. I will be giving instructions.

However, in the above-mentioned information transfer, the measurement results from the light chain detection device NTU on the exchange side are always transferred to the regulation control device C0NT at regular intervals regardless of whether there is a change in the situation. However, as the number of exchanges (stations) in the network increases, the burden on the regulation control device C0NT becomes greater, and there is a risk that it will not be possible to obtain sufficient measurement results necessary for determining actions. .

The present invention has been made in view of these points, and the measurement results are transferred to the regulation control device depending on whether a light chain state is detected or not.

In other words, when there is no detection of the light chain state, information is transferred from the light chain detection device on the switch side, reducing the load on the regulation system control device by connecting four devices, and the light chain state is detected as follows. In the case of ``excuse'', the light chain detection device sends out information, and until it receives an information transfer stop signal from the regulation control device, it transfers information indicating the state of the station every basic cycle, and the regulation control device processes the information. It is designed so that you can get enough information to make a decision.

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 is a simplified diagram of a light chain information transfer system showing an embodiment of the present invention, in which the DET measures the busy rate of a common device such as a group of input registers at a certain time during the basic cycle and at certain intervals. This is a light chain detection device that measures and totals the information and starts sending out information when a preset detection threshold for starting light chain information sending is exceeded.

Moreover, once the device starts sending out information, the measurement results are sent to the regulation control device C at every basic cycle regardless of the light chain state.
The data is continuously transferred to 0NT.

By the way, when the regulation control device C0NT receives information, that is, measurement information, from the exchange side via the dedicated line, it judges the situation and makes a processing decision.

Here, the regulation control device C0NT continuously obtains measurement results from the light chain detection device DET on the exchange side at regular intervals, and aggregates and analyzes the measurement results to determine the situation so that the corresponding exchange can escape from the light chain state. Determine whether or not.

When it is determined that the light chain state has been released, an information transfer stop signal is sent to the light chain detection device DET of the corresponding exchange.

When the light chain detection device DET receives the information transfer stop signal, it resets the light chain detection state, stops the transfer of measurement results, continues to measure and total the busy rate of the common device, and sends preset width edge information. Whether or not the starting detection threshold is exceeded is determined by monitoring the measurement results.

As described in detail above, according to the present invention, the light chain detection device DET on the exchange (office) side does not transfer measurement results during normal call conditions, so the burden is placed on the regulation control device C0NT on the network management device side. On the other hand, when detecting a light chain state, the measurement information from the exchange side is sent at regular intervals until a stop signal is transferred from the network management equipment side, so that regulation control is possible. Since the device C0NT can collect enough information necessary to judge the situation and decide on the treatment, it is expected that the treatment will be appropriate and the burden on the maintenance personnel will be lightened.
