Abstract

PURPOSE:To execute no unnecessary control by constituting a titled system so that a control device sends out control information of a specified subscriber to a regulating device corresponding to the switching device concerned based on a repeating pattern determined in advance, by congestion information of the specified subscriber received from an extracting device. CONSTITUTION:When a release of a congestion extracting device DETi of a switchboard is detected, a control unit CU releases a relay Ri of an incoming trunk, and waits for a reception from other congention extracting device DET. On the other hand, with respect to the received congestion information, the control unit CU refers to a repeating pattern by a extracting device DET number (i). Based on this repeating pattern, for instance, regulation control relays F0-Fm in outgoing trunks OGT0-OGTm corresponding to a regulating device number are driven. When it has been ended to send out the control information, the relays F1, F2...Fi and Fm which have been driven are released, and it is ended to repeat and sent out the control information.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a subscriber regulation system for regulating subscriber calls in a telephone exchange network. , The intruder's call in the area conversation order appears as a busy connection on the switching device. When abnormal traffic occurs to a particular subscriber, the switching equipment will have multiple busy connections to that subscriber, thus deteriorating connections to other subscribers. Sometimes this can lead to a situation where the exchange equipment goes down. Furthermore, if abnormal traffic occurs to multiple subscribers of the same switching device, the transmutation device itself becomes congested, which deteriorates the connection to other subscribers. Therefore, if abnormal traffic to a particular subscriber is detected, it is necessary to restrict connections (calls) to the subscriber or the switching equipment as soon as possible and at the entrance to the switching network. Various types of regulations are being considered for such regulations. For example, as shown in Fig. 1, in a general switching system, one control device (,'(extraction device 1 connected to JNT) H'l'j is installed in the switching device SWj, and the switching device SWj is Equipment S~V
The busy connection status and corresponding subscriber number at Tj are detected, and when abnormal traffic occurs for a specific subscriber, the extraction device 17 h: Tj sends the subscriber number to the control device C0 to 1. Send out. Having received such information, the controller device C (J N 'l' will all control the outgoing connection operation to the subscriber under 4 in the respective communication devices (IA devices SW0 to SWm). ``I agree.

In the event of Q-person congestion, control was provided to restrict outgoing calls to the switching equipment. However, in such a system, the control device C (all control devices under the JNT military) will be uniformly enforced, and the group of subscribers accommodated by a certain exchange device d will be different from the group of subscribers accommodated by that exchange device. In general, there is a drawback that restrictions are imposed unnecessarily even when there is little economic connection and the traffic between sub-switching devices is significantly lower than that of other switching devices.

The purpose of the present invention is to eliminate such drawbacks, and the control device does not send regulation information to the regulation device for the exchange device in which the 4-stroke is occurring and the switching device with low traffic rate. Controls outgoing connections to specific subscribers (switching equipment) by sending control information only to switching equipment.1ttl
It provides the Udaishaki+111 method for J.

The subscriber restriction system of the present invention is provided with an extraction device for detecting abnormal traffic for 10 subscribers and a restriction device for restricting outgoing calls to specific subscribers in a fault recovery switching device, and each of the extraction device and restriction device is 1 1iilJ connected
A control device is provided, and based on the width information of a specific subscriber received from the extraction device! The control device 7 is characterized in that it sends regulation information to the corresponding regulation device according to a predetermined relay pattern.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

Figure 2 is a diagram of a general relay system.The medium-speed pattern created by the control device C (Circuit diagram showing details of JNT, Figure 3 is 1iIl shown in Figure 2) in Figure 1 is shown in Figure 2. FIG.

In FIG. 2, ICTo and lcTm are the incoming trunk circuits (J
T 6 %-m is an outgoing trunk circuit corresponding to the regulating device RC shown in FIG. 1, and shows the communication path section and the control section separately. This control section is directly connected to the control unit (UU) which sends out the difficult pattern.

Further, a communication path section in which multiple human trunks ICTo-1cTm are connected is connected to the control unit CU via multi-frequency signal receivers MFkLk and C. Further out the trunk (
The communication path section of the JGT is a transmitter that transmits a frequency fo%f. This is used, for example, in 2-out-of-6 signaling.

In the 4 system diagram in Figure i1, in the exchange - MinatojQsWoj, 4 regular traffic occurs to a subscriber whose (area code) + (city code) + (subscriber number) is 56321-2222'. Then, the extraction device IJE'l'j sends the good news of subscriber number 56321-2222' to the control device U (JNT).

directly (not particularly shown). The method of determining the regulation rate is not directly related to the present invention, so it will be omitted. That is, since the restriction information (restricted subscriber number, restriction rate) is not sent to the switching device (8W (1t 8 Wm'...)), the restriction is exercised only in the switching device based on the relay pattern.

If the abnormal breadth of people with specific power in the area occurs more than 5 subscribers (for example, 5 subscribers), the pattern of exchange and Minato foundation, for example, the area code It should be easy to understand that the control is such that the data (number) is transmitted according to the relay pattern.

Father, even if regulations are implemented according to such a relay pattern (including tightening of the restriction rate), flattery and flattery will not end, in which case it will be necessary to ignore the relay pattern and regulate all exchange devices. However, this method is also easy to understand. Such an intermediate conduction pattern can be increased in advance depending on the amount of traffic between exchange devices.9 The method for creating it is easy and will therefore be omitted.

As explained above, the present invention can be expected to have the effect of not implementing unnecessary regulations by sending regulation information to a regulation device using a predetermined central pattern when spy information is received.
