DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for restricting the transmission of a local line, and more particularly to a system for restricting the transmission of a local line in a private branch exchange by using charging data of a transmission extension terminal.

[0002]

2. Description of the Related Art In a conventional call control system based on billing data in an automatic exchange, it is set that a call extension is determined from a call extension terminal, and a maximum billing index for call connection (a unit charge corresponding to a call-to-ground region). (Eg 1
The maximum value of the charging index table that specifies the number of seconds that can be talked at 0 yen) is set in advance.

When the calling extension terminal performs a calling operation, the charging index table is searched, and the charging index of the destination to which the call is transmitted by the calling operation is compared with the maximum charging index set in the charging index table. By doing so, it was determined whether outgoing connection restriction was possible.

[0004] For example, in the connection regulation system described in Japanese Patent Application Laid-Open No. 3-278658, a charging index, which changes every hour when a subscriber calls, is compared with an upper limit charging index registered in advance by the subscriber. When the former charging index exceeds the latter charging index, the call connection is regulated.

[0005]

In the connection control system based on the conventional charging data, the subscriber of the transmitting terminal determines whether or not to perform the restriction determination, and the maximum charging information that can be transmitted is also set in the transmitting terminal. , It was not possible to strictly regulate outgoing calls to areas with high call rates. Therefore, there is a problem that it is not so effective in reducing the call charge.

SUMMARY OF THE INVENTION It is an object of the present invention to restrict the outgoing call to a high-charge area by judging whether or not the call can be restricted based on the charging index set for the extension class data when the extension calls the local line. An object of the present invention is to provide a local line transmission regulation system that reduces fees.

[0007]

According to the present invention, in a private automatic exchange, when an extension terminal originates an office line, charging index data corresponding to the extension class of the originating extension terminal and charging index data corresponding to the originating call number are provided. A decision is made as to whether or not line transmission is possible based on the data. If the result of this decision indicates that line transmission is not possible, a means for automatically restricting line transmission is provided .

[0008] Also, extension class data corresponding to the extension terminal, office line transmission route data corresponding to the selected number dialed by the transmission extension terminal, and charging corresponding to the extension class for each office line transmission route. Registering means for registering the index data and the charging index data corresponding to the calling station number; and transmitting the line transmission restriction data from the charging index data corresponding to the line transmitting route and the extension class data corresponding to the extension terminal. Determining means for determining whether or not the line transmission can be performed, and when performing the line transmission restriction, the determination means searches the charging index data and the extension class data for all the detour routes and searches for the detour. It is possible to obtain a local line transmission control method characterized by determining whether or not a local line can be transmitted to a route.

Furthermore, the registration means, and extension class data memory for storing the extension class data corresponding to the extension terminal, the charging index data memory for storing billing index data corresponding to the calling Other ID, the originating extension outgoing route that the terminal stores the public line outgoing route data memory for storing the office line outgoing route data corresponding to the selected number dialed, the charging index data corresponding to the extension class for each of the office line outgoing route A station circuit comprising: a storage circuit having a regulated data memory; and a maintenance terminal for performing an operation of registering the various data in the storage circuit.

FIG. 3 is a flowchart showing the flow of the local line transmission receiving process in FIG.

Referring to FIG. 1, a private branch exchange in this embodiment includes a plurality of extension terminals (EXT) 11, 12,.
.., A communication path switch (SW) 20 accommodating 1 m;
A plurality of local line transmission routes (RT) 31, accommodated in W20,
, 3n, a central processing unit (CPU) 50 for controlling all sequences in the private branch exchange, a maintenance terminal (MAT) 40 connected to the CPU 50 through an input / output interface (INF) 41, and a storage device. (ME
M) 60.

As shown in FIG. 2, the MEM 60 stores an extension class data memory (CLSM) 62 for storing extension class data (CLS) corresponding to an extension terminal (EXT), and charging index data corresponding to an originating call number (YY). A charging index data memory (CHGM) 64 for storing, and a line transmission route data memory (RTD) for storing the line transmission route data (RT) corresponding to the selection number (XX) dialed by the calling extension terminal.
M) 61 and an outgoing route regulation data memory (RTRM) 63 for storing charging index data corresponding to the extension class (CLS) for each office line outgoing route (RT).

The maintenance person performs a registration operation from the MAT 40 and registers various data in the MEM 60 in advance.

That is, the MAT is operated by the registration operation of the maintenance person.
Various data input from 40 are INF41, CPU5
0 is stored in the MEM 60.

Thus, the route information (eg, RT31, RT32,..., RT corresponding to the dialed selection number "XX") can be transmitted to the RTDM 61 in accordance with the selection number.
3n) is set.

EXT compatible extension class data (for example, CLS "1" for EXT11,
CLS "2" for EXT12 and CL for EXT1m
S “3” ) is set.

Further, the transmission route (R

Next, the operation of this embodiment will be described with reference to FIGS. 1, 2 and 3.

For example, assuming that the EXT 11 has dialed the selection number "XX" for local line transmission, the CPU 12 searches the RTDM 61 with the selection number "XX" by a known method and reads out the RT 31 (step S1).

Next, the CPU 50 searches the CLSM 62 with the EXT 11 of the calling extension terminal, and retrieves the CLS of the calling extension class.

Next, the CPU 50 searches the CHGM 64 with the originating game number "YY" to read the charging index "5", and further searches the RTRM 63 with the RT31 and CLS "1" to read the maximum charging index "6".

Then, the CPU 50 compares the charging index "5" with the maximum charging index "6" to determine whether or not the EXT 11 can transmit a local line (S3, S4).

Here, if the charging index is "5"<the maximum charging index is "6", the CPU 50 determines that the local line can be transmitted from the EXT 11 (NO in S4), and performs a known local line transmitting connection process. (S5) The process ends.

If the charging index "5"> the maximum charging index "6", the CPU 50 determines that the local line transmission from the EXT 11 is not possible (YES in S4) and accesses the RTDM 61 to access the next transmission route. Is read (S6).
It is determined whether a detour to the RT 32 is possible (S7).

The YES at S 7, i.e. bypassing possible to RT32, performs processing to S6 returns to S3, bypassing possible outgoing route disappears (becomes NO at S7) until the process is repeated.

If NO in S7, that is, if there are no more detourable outgoing routes, a known connection restriction process is performed (S7).
8) The process ends.
