Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection regulation information verification system for long-distance/international automatic instant calls or relay calls at a telephone office with a relay stand.

Recently, much progress has been made in making long-distance calls and international calls automatic and instant, but due to the serviceability for Canadians or connection restrictions (for example, for subscribers who have not paid their bills), it is difficult to make waiting calls or instant relay calls difficult. It may be necessary to use it in combination with table handling.

In this case, the conventional connection regulation information verification method prepares file memories of connection regulation information for all applicable subscribers of the central telephone office separately for the automatic instant connection system and relay board connection system, and independently verifies the connection regulations for each system. was going there.

Therefore, the dual management is complicated and the file memory is uneconomical.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connection regulation information matching method that eliminates the drawbacks of the prior art described above, makes file memory economical, and facilitates information management.

A feature of the present invention is that the connection regulation information is integrated and stored only in either the file memory of the automatic instant connection system or the file memory of the relay board connection system, and the file memory is not accessed from the processing device of the other system. The connection regulation information matching method is capable of making a verification request for the connection regulation information and performing connection regulation.

In detail, each processing device proceeds with the connection in accordance with the request of the calling subscriber, completes the verification of connection restriction information during the calling subscriber's call connection, and When a subscriber is identified as a subscriber subject to regulation, desired connection regulation is carried out in real time by forcibly restoring the calling connection.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a relay system diagram of an embodiment of the connection restriction information matching method according to the present invention, and FIG. 2 is a state transition diagram thereof.

Here, ICT is incoming trunk, OGT is outgoing trunk, IR is incoming register, OS is outgoing sender,
OPT is the operator's trunk, NW is the communication path network, CPU is the processing unit for automatic instant connection and other necessary connections, MCHC is the multiplexer channel, FMC is the same file memory, CBD
is an attendant console, POSC is an attendant console controller,
POP is a processing device related to relay board connection, MCHP is
The multiplexer channel, FMP is the file memory, and IFC is the information control device between the processing unit CPU and POP.

Below, connection restriction information (for example, blacklist BL of unpaid subscribers) is stored in the file memory FMP.
The following explanation assumes that it is stored in .

First, the case of automatic instant connection outside the city and internationally will be explained.

Number information from the local station is sent to the incoming trunk.
It is received at the input register IR through the ICT and communication path network NW (state in Figure 2).

The above number information is received in the order of first the called subscriber number and then the calling subscriber number, as is known in the art.
Read by the processing unit CPU.

As is well known, the processing unit CPU analyzes this, selects and captures the outgoing trunk OGT to the other party's station related to the called subscriber number, and connects the outgoing sender OS to the communication path network while holding the incoming trunk ICT. Connect to the corresponding outgoing trunk OGT via the work NW, and have the outgoing sender OS send a predetermined called subscriber number to the other party (state).

On the other hand, the processing unit CPU transfers the called subscriber number to the multiplexer channel MCHC, the information control unit
It is sent to the processing unit POP via IFC, but the time required for this is extremely short compared to the time required to send the called subscriber number (usually about 50 ms or less).

Processing device POP multiplexer channel
The file memory FMP is accessed through the MCHP, and based on the received calling subscriber number, it is read out whether or not the subscriber is recorded in the blacklist BL of the file memory FMP as a subject of connection restriction.

For example, if this black list BL is configured as a sequential file in which one bit corresponds to one subscriber, it can be read only once, and the time required for reading it is short (usually about
50ms or less).

The processing device POP checks the read result and returns the presence or absence of regulatory information regarding the calling subscriber to the processing device CPU, but the time required for this is similar to the above (usually about 50ms). be.

As a result, if the calling subscriber is not subject to connection restrictions, the processing unit CPU connects the incoming trunk ICT to the outgoing trunk OGT via the communication path network NW after the outgoing sender OS completes sending digits, and Forces subscriber calling operation (state).

If it is subject to connection restrictions, you can immediately enter trunk ICT.
is placed in a forced recovery state, and the desired connection of the calling subscriber is not made.

This can be done in a short time after the processing device CPU is started (the total time involved in the operation of checking the connection regulation information, for example, about 150 ms or less according to the above example).

Therefore, since it usually takes at least one second to send out the numbers, either connection progress or forced recovery can be performed at a sufficiently early stage before the number sending is completed.

In the unlikely event that the return of the check result of the blacklist BL is delayed for some reason, if the same check result is returned after the number transmission is completed, the same check result will be obtained even if the status remains as it is. There is no practical problem in terms of exchange processing or service even if the state is changed from 1 to 1 or forced to be restored.

Next, in the case of a relay stand connection using the relay stand CBD, the operator must connect the incoming trunk ICT, call path network
NW accepts the connection request from the calling subscriber via the operator trunk OPT, and based on the operator's operation, from the relay station CBD to the relay controller POSC,
A connection regulation information verification request is sent to the processing device POP via the multiplexer channel MCHP.

Processing device POP multiplexer channel
The file memory FMP is accessed via the MCHP, and the presence or absence of regulatory information regarding the subscriber is sent back to the relay station CBD in the same manner as described above, and this is displayed.

Based on the results, the operator performs the connection operation desired by the calling subscriber, or notifies the calling subscriber that the connection is restricted without performing the desired connection operation, as is well known.

Note that, as in the case of automatic instant connection, the desired connection operation may be performed immediately after receiving the connection request, and the connection operation may be completed or canceled depending on the connection regulation information collation result.

In the above embodiment, the blacklist BL related to connection restriction information is not the file memory FMP, but
It may be stored in the file memory FMC.

In this case, the operation of checking the connection regulation information will be in the same reverse direction as the one described above, but the detailed operation can be easily inferred from the above explanation.
The explanation will be omitted.

As described above in detail, according to the present invention, connection regulation information can be converted into a file source, so that in a telephone office where a relay stand is installed, etc., the file memory can be saved more economically by reducing the memory capacity, and the information A remarkable effect can be obtained in facilitating management.
