Abstract

PURPOSE:To allow a subscriber line exchange to conduct the district regulation by providing a means transferring district congestion regulation information to a subscriber regulation ground identification device and a means assigning the said information to a tenant of the subscriber regulation ground identification device to have priority over the subscriber regulation information to a subscriber regulation controller. CONSTITUTION:When a district congestion detector 4 of a toll exchange 2 detects a district congestion, the detector 4 transmits congestion information Cn to a district regulation controller 10 via an interface controller 12 and a subscriber regulation controller 11. The controller transmits the regulation information to the subscriber regulation ground identification device 6 of plural subscriber line exchanges 3 existing in the said district and the said device 6 regulates a call of a tenant by the subscriber line exchange 3. The controller 11 regulates the district. In controlling competing tenants, the district regulation is regarded as it has priority, and when all tenants are in use, the subscriber regulated already is compelled and the district regulation is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field of the invention The present invention relates to a regional regulation system for regulating outgoing calls in a specific area when abnormal congestion occurs in a specific area in a public telephone network. be.

(2) Technical background In public telephone networks, when an earthquake disaster occurs in an area, there is an abnormally large number of calls.

As a result, instead of the switching center being in a heavy traffic state and the number of overflow calls increasing, the heavy traffic state of the switching center will spread to the higher-level offices, and calls for emergency and important subscribers will be reduced. Processing becomes unmanageable.

To this end, measures have been taken to control regional congestion, but they have not been perfect.

(3) Prior Art and Problems FIG. 1 is a relay system diagram for explaining a conventional regional congestion control system. In the figure, 1 is a toll terminating exchange, 2 is a toll originating exchange, 3 is a subscriber exchange, 4 is a local congestion detection device, 5 is a local restriction ground identification device, and 10 is a local restriction control device. First, the toll terminating exchange 1 is provided with a regional congestion detection device 4, and when it detects regional congestion, it transmits congestion information On to the regional regulation control device 10. The regional regulation control device 10 controls the regional regulation ground identification device 5 provided in the toll exchange 2 of the corresponding region in order to control call congestion in the corresponding region.
The regional restriction ground identification device 5 that has received the restriction information restricts outgoing calls at the toll exchange 2. Therefore, restrictions in congested areas do not apply to the incoming calls indicated by O, ~1, but only to the outgoing calls, CO0 to CO1. That is, in the conventional area regulation system, the lines of priority subscribers are separated at the toll exchange, and therefore the subscribers cannot be regulated. Another drawback was that network congestion between subscriber line exchanges and toll-originating exchanges was unavoidable.

(4) Purpose of the Invention In view of the above-mentioned drawbacks of the conventional art, the present invention changes the location of enforcement from the toll exchange to the subscriber line exchange, and enables regulation to be carried out before the lines of priority subscribers are separated. The purpose of the present invention is to provide a regional regulation method that allows regional regulation to be carried out at the subscriber line exchange based on the technical philosophy of preventing network congestion between the subscriber line exchange and the toll exchange. .

(5) Structure and object of the invention According to the present invention, in regional congestion regulation control in traffic control for controlling incoming call congestion, a means for transmitting regional regulation information to a regulation ground identification device for subscribers, This is achieved by providing a region regulation method characterized by providing a means for assigning region regulation information to a tenant of a subscriber regulation ground identification device in a control device with priority over subscriber regulation information.

(6) Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram for explaining one embodiment of the area regulation system according to the present invention. In the drawing, the same reference numerals as those explained in FIG. 1 indicate the same contents.

6 is a subscriber restriction ground identification device, 11 is a subscriber restriction control device, 12 is an ink face control device B113 is an interface control device A, respectively. The order of regional regulation is that when the regional congestion detection device 4 installed in the toll exchange 1 detects regional congestion, the regional congestion detection device 4 turns on the congestion information to the interface control device B12 and the subscriber regulation control device 11. It is transmitted to the regional regulation control device 10 via. The regional regulation control device 10 transmits regulation information to the subscriber regulation ground identification device 6 provided in a plurality of subscriber line exchanges 3 existing in the corresponding area, and receives the regulation information from the regional regulation ground identification device 6. Device 6
The subscriber line exchange 3 regulates outgoing calls. The subscriber regulation control device 11 regulates the area, and the regulation of subscribers is carried out by the subscriber regulation ground identification device, so it is necessary to control competing tenants.

When controlling competing tenants, ■ Consider regional regulations as a priority, and if a tenant is fully occupied, expel the already regulated subscribers and implement regional regulations.

■ Regulations with low priority when expelling subscriber regulations'f
I: Select.

Next, referring to FIG. 3, a configuration example of the regulation information tenant allocation in the area regulation system according to the present invention will be explained.

The zoning regulation information from the zoning regulation control device IO shown in FIG. 2 is transmitted to the control circuit via the zoning regulation information receiving circuit 23 and the zoning regulation information receiving buffer 24. Regional regulation tenant allocation is controlled by control circuit 27
The vacant tenant memory of the regulation information storage circuit 30 is searched, the tenant of the subscriber regulation ground identification device is determined, and the regulation information is transferred to the subsidiary via the regulation information transmission buffer 2 and the transmission circuit 29.

If all the tenants are in use, the evicted subscriber regulation determination circuit 26 is notified of this, and the evicted subscriber regulation circuit 26 stores the subscriber regulation information with the lowest regulation priority in the regulation information storage circuit 30. Compare and decide.

Control circuit 2 controls the determined tenant by area regulation and tenant allocation.
7, the control circuit 21 cancels the restriction on the subscriber determined to be kicked out, and transfers the tenant allocation to the area restriction to the affiliated area.

(η Effects of the Invention As explained in detail above, the regional regulation system of the present invention has great effects such as eliminating omissions in regional regulations and preventing network congestion between subscriber line exchanges and toll-originating exchanges. It is something.
