Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to incoming call regulation for telephone exchanges, and more particularly to a representative group of incoming call regulation methods and devices.

[0002]

2. Description of the Related Art Conventionally, in this type of representative group incoming call restriction method, is the number of calls exceeding the maximum allowable number of calls for each representative group in the incoming call analysis processing shown in Japanese Patent Laid-Open No. 134953? It was done by judging whether it was.

[0003]

In the above-mentioned conventional representative group incoming call regulation method, according to the incoming call analysis processing, the implementation confirmation is performed before it is determined that a large number of calls are concentrated in one representative group. However, the processing time per incoming call becomes extra, and when a large number of incoming calls are concentrated in a large representative group, the load on the exchange significantly increases.

Further, even if the incoming call restriction is not applied, if the calls are concentrated in one representative group, they are processed as busy in the incoming call analysis process, and there is a problem that the processing time is further increased.

An object of the present invention is to periodically integrate the number of incoming calls without judging whether or not the maximum allowable number of calls in the representative group is exceeded by the incoming call analysis processing, and perform incoming call restriction at any time according to the result. An object of the present invention is to provide a representative group incoming call control method and apparatus.

[0006]

According to the representative group incoming call control method of the present invention, a telephone call is made by analyzing the vacant state of the called party to determine whether or not the maximum allowable number of calls for each representative group is exceeded. In the method of restricting incoming call of the representative group to the incoming call congestion of the representative number subscriber in the exchange method, a step of assigning a shortened special number to the representative number subscriber and integrating the incoming calls at a predetermined cycle for each of the special numbers And a step of restricting the incoming call based on the result of integration of the incoming calls, and a step of converting a special number into a representative subscriber number for a call that is not processed as a lost call due to the incoming call restriction.

Further, the step of restricting the incoming call sets the ratio of the incoming call to be processed as a lost call by the ratio of the integrated value for every predetermined period to the maximum allowable number of calls preset for each representative number subscriber. Further, the ratio of the incoming call to be processed as the lost call is obtained by subtracting 1 from the integer value of the ratio of the integrated value of the previous cycle and the maximum allowable number of calls as the denominator. What is set as a ratio using an integer value as a numerator is also included in the present invention.

A representative group of incoming call control devices of the present invention is
In the incoming call control device for the incoming call congestion of the representative number subscriber in the telephone exchange method, which was performed by analyzing the idle state of the called party to determine whether the maximum allowable number of calls for each representative group was exceeded, the representative number subscriber Each time a shortened special number assigned to is received, a step of accumulating incoming calls in a predetermined cycle for each special number, and an incoming call regulation corresponding to the result of the integration of the incoming calls based on the result of integrating the incoming calls. Means to do
There is provided means for converting a special number into a representative subscriber number for a call that has not been processed as a lost call due to the incoming call regulation and transferring the call to a call connection process.

Further, the means for restricting the incoming call calculates the ratio of the previous integrated value for each predetermined period to the maximum allowable number of calls preset for each representative number subscriber, and the restriction corresponding to the calculation result. The ratio of incoming calls to be processed as lost calls is set by the ratio, and the ratio of incoming calls to be processed as lost calls is a denominator of the integer value of the ratio of the integrated value of the previous cycle and the maximum allowable number of calls. In the present invention, the ratio is set as the numerator of an integer value obtained by subtracting 1 from the integer value.

[0010]

The representative number subscriber is given a special number with a small number of digits, the number of incoming calls by the special number is integrated in a predetermined cycle, the ratio of the integrated value to the maximum allowable number of calls is calculated, and the calculated value is calculated. Since the incoming call restriction is performed with reference to a predetermined restriction value corresponding to, incoming call restriction corresponding to the number of incoming calls is performed at any time without analyzing the incoming call.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a flow chart of an embodiment of the incoming call regulation method of the representative group of the present invention, FIG. 2 is a flow chart of updating the regulation table shown in FIG. 1, and FIG.
0, FIG. 3 (b) is a diagram showing the restriction rate table 21, FIG. 3 (c) is a diagram showing the maximum acceptable value table 22, and FIG. 4 is a block diagram of an embodiment of the incoming call regulation device of the representative group of the present invention. .

A special number with a small number of digits is given to each representative number subscriber.

The incoming call restriction device 10 of the representative group of the present invention inputs the incoming call when it judges that the call is assigned to the special number as a result of analysis of the dialed digits of the incoming call of the special number connection section 1. In addition, the incoming call regulation device 10 of the representative group calculates a counter 20 and a regulation rate table 21 provided for each special number, a maximum acceptable call count table 22, a regulation unit 2 that implements regulation, and a regulation rate. The restriction rate calculation unit 3 and the number conversion unit 4 for converting the special number into the representative number are included. The counter 20 is a counter that integrates the calls dialed to the special number within a predetermined cycle. The integrated value is extracted in a predetermined cycle and divided by the maximum number of calls that can be accepted by the restriction value calculation unit 3 to calculate the restriction value. When it is done, it is cleared to 0. The maximum acceptable call number table is a table in which the maximum acceptable call number for each special number is described. The regulation rate calculation unit 3 sequentially extracts all the counters 20 at a predetermined cycle, divides them by the corresponding maximum number of acceptable calls, and writes the value in the regulation rate table, and then clears the counter 20 to zero. When the special number has an incoming call, the restriction unit 2 refers to the restriction rate table 21 to execute the restriction. Number converter 4
Converts a special number into an original representative number and outputs an incoming call that exceeds the regulation. The call processing transfer control unit transfers the output call of the number conversion unit to the call processing unit.

Next, the operation of the incoming call restriction device of the representative group of this embodiment will be described.

Now, when the exchange recognizes that it is a special number at the stage of numerical analysis of the dial sent from the subscriber, the numerical value of the counter 20 of the special number is 1
Is added (step 11). Next, the regulation rate table (21) is read (step 12). When the restriction rate is 1 (Yes in step 13), the incoming call is converted into a representative number (step 15) and transferred to call connection. When the restriction rate is 2 or more, the incoming call for each displayed integer value is converted to the representative number (Yes in step 13) and transferred to the call connection (step 15), and the other incoming calls are lost calls. As a result, the busy tone is transmitted (step 14).

Further, the update of the restriction table 21 is always processed in a predetermined cycle for all special numbers (step 3).
1) For each special number, the value of the counter is divided by the value of the maximum number of calls accepted table 22 to obtain a value (step 3).
2). It is determined whether or not this calculated value is larger than 1 (step 33), and if it is 1 or less, it is set to 1 (step 3
4) When the calculated value exceeds 1, the regulation rate table 21 is written up to two digits after the decimal point (step 35). After that, the counter 20 is cleared to 0 (step 36).

The maximum number of calls that can be accepted table 22 is changeable. When no restriction is applied or when a special number is processed, it can be realized by setting the value of the maximum number of calls that can be accepted table 22 to zero. In this case, the calculated value of the regulation rate is 1
Becomes

[0019]

As described above, according to the present invention, a special number is given to a representative group, and incoming control is performed at the stage of receiving a special number before regular incoming call processing by the representative number. Even if a large number of calls are temporarily concentrated in the area, the load on the exchange can be suppressed.
