Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a regulation control restart processing method, particularly an interface control device that collects congestion information sent from a plurality of exchanges and transmits it to a regulation control device;
Resume regulation control in a traffic control system comprising a regulation control device that analyzes the congestion information transmitted from the interface control device, creates necessary regulation information, and transmits it to the exchange via the interface control device. Regarding processing method.

(b) Background of the technology In the telephone network, the communication function of the telephone network is disrupted due to an abnormal concentration of incoming calls to areas affected by earthquakes, typhoons, etc., or to specific subscribers who make telephone reservations. Congestion may occur.
Attempts have been made to apply a traffic control system that detects such incoming call congestion at an early stage, eliminates the cause, and prevents disruption of the communication function of the telephone network. FIG. 1 is a diagram showing an example of the configuration of a traffic control system to which the present invention is applied. In FIG. 1, a congestion detection device 2 attached to each exchange 1 constituting the telephone network constantly monitors the operating status of each exchange 1 (for example, the total blockage rate of input registers), and at predetermined intervals The situation is transmitted as congestion information c to the interface control device 4 or 4'. In addition, the congestion detection device 2 detects a subscriber who is in a call congestion state (for example, the number of overflow calls has exceeded a predetermined value) among the accommodated subscribers, and detects the subscriber's telephone number and the degree of congestion (for example, overflow The number of calls) is included in the congestion information c and transmitted to the interface control device 4 or 4'. The interface control device 4 or 4' is commonly installed in a plurality of exchanges 1, collects congestion information c transmitted from each exchange 1 under its control, and transmits it to the regulation control device 5. The regulation control device 5 is commonly installed in a plurality of interface control devices 4 or 4', and analyzes congestion information c transmitted from each affiliated exchange 1 via each interface control device 4 or 4', and specifies the congestion information. When it is determined that incoming call congestion has occurred in a region or a specific subscriber (hereinafter collectively referred to as destination), restriction information r including telephone numbers to be restricted, restriction rate, etc. is created, and each interface control device 4 or 4' to the restriction site identification devices 3 attached to each exchange 1 within the range related to the site, thereby restricting calls to the site.

(c) Prior Art and Problems FIG. 2 is a diagram showing an example of a conventional regulatory control system, and FIG. 3 is a diagram showing an example of the information transmission process in FIG. 2. In FIG. 2, congestion information c transmitted from each interface control device 4 or 4' (not shown) to the regulation control device 5 is sequentially stored in the reception buffer 7 via the reception circuit 6. The regulation logic circuit 8 sequentially extracts the congestion information c accumulated in the reception buffer 7, analyzes it according to a predetermined logic, and creates regulation information r when it is determined that incoming congestion has occurred at the destination. . Further, the regulation logic circuit 8 selects an empty tenant memory from tenant memories that store a predetermined number of regulation information r set in the regulation information storage circuit 9, and when an empty tenant memory is captured, The registration of the regulation information r is completed by adding the tenant number assigned to the tenant memory to the created regulation information r and storing it in the captured tenant memory. The registered regulation information r is once stored in the transmission buffer 10, and then transmitted all at once to a required interface control device 4 or 4' (not shown) via the transmission circuit 11.

As is clear from the above explanation, in the conventional regulation control system, the regulation control device 5 analyzes the congestion information c transmitted from the congestion detection device 2 via the interface control device 4 or 4',
When it is determined that incoming call congestion has occurred, restriction information r is created and transmitted to the restriction ground identification device 3 attached to the required exchange 1. If the interface control device 4 is currently stopped moving, the regulation ground identification device 3 attached to each affiliated exchange 1 cannot receive the regulation information r sent from the regulation control device 5, and each exchange 1 is unable to receive the regulation information r sent from the regulation control device 5. It is in an unregulated state.
When the interface control device 4 in such a state starts operating, the regulation information r will be changed to the regulation control device 5 from now on.
Each time the information is transmitted from the affiliated exchange 1, it is transferred to the restriction ground identification device 3 attached to the affiliated exchange 1, and the necessary restrictions are implemented. Therefore, each exchange 1 under the control of the interface control device 4 that has started operating implements regulations corresponding to all the regulation information r that the regulation control device 5 is currently registering in the tenant memory in the regulation information storage circuit 9. The drawback was that it took a lot of time. In order to eliminate such drawbacks, it may be considered to manually set each exchange 1 under its control to the required regulatory state before the interface control device 4 starts operating, but such manual settings require a lot of effort. There is also the risk of setting incorrect regulations.

(d) Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of the conventional regulation control system as described above, and to enable each switch under the control of an interface control device that has started operation to regulations based on regulatory information,
The goal is to realize means that can be implemented quickly and appropriately.

(e) Structure of the Invention The object of the present invention is to provide an interface control device that collects congestion information periodically transmitted from a plurality of affiliated exchanges, indicating the operating status of the exchange, and transmits the information to a regulation control device; Analyzes congestion information transmitted from the control device, and when it is detected that it is necessary to regulate an exchange, creates and registers regulation information indicating the content of the restriction, and transmits it to each affiliated exchange via the interface control device. In a traffic control system having a regulation control device, when the interface control device starts operation, it transmits operation start information indicating that the operation has started to the regulation control device, and the regulation control device When receiving the start-of-operation information transmitted from the device, it creates comprehensive regulation information that includes all the currently registered regulation information, and sends it to each affiliated exchange via the interface device that transmitted the start-of-operation information. This is achieved by transmitting the information and setting each exchange to a regulated state corresponding to the regulated control information registered in the regulated control device.

(f) Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings. FIG. 4 is a diagram showing a regulatory control restart processing method according to an embodiment of the present invention, and FIG. 5 is a diagram showing an example of the information transmission process in FIG. 4. Note that the same reference numerals indicate the same objects throughout the figures.
In FIG. 4, an information identification circuit 12 and a restart control circuit 13 are provided within the regulation control device 5. Congestion information c transmitted from an interface control device 4 or 4' (not shown) is transmitted to an information identification circuit 12 via a receiving circuit 6. The information identification circuit 12 congests the received information with information c
When it is identified as such, it is stored in the reception buffer 2. Thereafter, the regulation control device 5 processes the congestion information c in the same manner as in FIG. 2. Next, when the interface control device 4, which has been stopped in operation, starts operating, it transmits the operation start information o to the regulation control device 5 (FIG. 5). The operation start information o transmitted from the interface control device 4 is transmitted to the information identification circuit 12 via the receiving circuit 6.
When the information identification circuit 12 identifies the received information as operation start information o, it transmits it to the restart control circuit 13. The restart control circuit 13 that received the operation start information o
extracts all the regulation information r being registered from the regulation information storage circuit 9, edits the comprehensive regulation information R including the regulation information r, and stores it in the transmission buffer 10. The comprehensive regulation information R is transmitted via the transmission circuit 11 to the interface control device 4 that has started operating. The interface control device 4 transmits the received general regulation information R to the regulation ground identification device 3 attached to each affiliated exchange 1. Each restriction ground identification device 3 implements restrictions corresponding to all the restriction information r included in the received comprehensive restriction information R to the corresponding exchange 1. As a result, each exchange 1 implements regulations regarding all the regulation information r currently registered by the regulation control device 5. Meanwhile, the interface control device 4', which had continued to operate until then,
The congestion information c transmitted from the controller is processed in the same process as described above, and when the restriction information r is created, it is also transmitted to the interface control device 4 as necessary and attached to the affiliated exchange 1. It is also transmitted to the restricted ground identification device 3.

As is clear from the above description, according to the present embodiment, the interface control device 4 that has started operating transmits the operation start information o to the regulation control device 5, so that all of the information currently registered from the regulation control device 5 can be transmitted. It is possible to receive the comprehensive regulation information R including the regulation information r, and to have each affiliated exchange 1 immediately implement regulations corresponding to all the regulation information r.

Note that FIGS. 4 and 5 are only one embodiment of the present invention, and the configuration of the regulation control device 5, for example, is not limited to that shown in the figures, and many other modifications may be considered. However, the effects of the present invention remain the same in either case. Furthermore, the configuration of the traffic control system to which the present invention is applied is not limited to that shown in the drawings; for example, the interface control device 4 is not limited to being provided in plurality for the regulation control device 5. , it is also contemplated that one interface control device is provided for the regulation control device 5 .

In such a traffic control system, if each switch 1 under its control is manually regulated while the interface control device 4 is out of operation, the regulation state of each switch 1 will be the same as that of the regulation control device 5. Registration information r that is being registered will no longer be supported.

Therefore, when the interface control device 4 starts operating, by applying the present invention, each switching equipment 1 under its control can be quickly put into the regulation state corresponding to the regulation information r currently registered in the regulation control device 5. Can be set.

(g) Effects of the Invention As described above, according to the present invention, in the traffic control system, the regulation control device transmits comprehensive regulation information indicating all regulation states currently registered to the interface control device that has started operation. , each exchange under the umbrella will be immediately set to the latest regulatory state, making it possible to implement prompt and appropriate regulations.
