Abstract

PURPOSE:To distribute call according to a fixed distribution rate and to generate the call to the all outgoing line groups at random by registering the call distribution rate, simultaneously, referring to a random number table, determining the sequence of outgoing line group selection for the plural outgoing line groups, and registering its result. CONSTITUTION:When a first call is generated, an exchange 1 reads the outgoing line group number in a pair with a random number 1 out of an outgoing line group selective sequence table 12, connects the call to the line of the designated outgoing line group, and the designation to know the outgoing line group to be next used is set at a random number 2. In the same way as above, the random numbers are successively increased by one at every call, the outgoing line group is designated, when the random number goes to 100, it returns to the random number 1 again, and the designation is repeated. Thus, for the outgoing line group to have received the distribution rate of 60%, 60 pieces of the call are distributed out of the 100 pieces of the call, and the call is generated at random.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a departure group selection system, and more particularly to a departure group selection system that allocates calls according to a predetermined allocation ratio. In cases where there are multiple telecommunications carriers in the country, each with their own international call lines, calls from other countries to the United States will be made by that carrier according to the allocation ratio agreed between the carriers in the United States. It was necessary to select a group of outgoing lines that corresponded to the above. In this case, a first example of the outgoing line group selection method is to set a value corresponding to the call allocation rate in a subtraction counting circuit provided for each outgoing line group, and then select the outgoing line group every time a call occurs. The calls are distributed in a predetermined order, and each time the value of the subtraction counting circuit is decremented by 1, and when the value of the subtraction counting circuit of all outgoing lines becomes "0", the initial state is returned. In the second example, as in the first example, a value corresponding to the call distribution rate is set in the subtraction counting circuit provided for each outgoing line group, and a call is generated. Then, the value of the subtraction counter circuit for the first outgoing line group is rQJ
, and then similarly supply calls to the second outgoing line group until the value of the subtraction counting circuit becomes "0", and in the same way, the subtraction counting circuit of all outgoing line groups If the value of
”, the system would return to the initial state.

[Problem to be solved by the invention]

In the first example, in the conventional outgoing line group selection method described above, the number of outgoing line group selections is predetermined for each outgoing line group each time a call occurs until the value of the subtraction counting circuit provided for each outgoing line group reaches rQJ. Since the calls are distributed in the order in which the initial value is set, the outgoing line group with the small initial setting value will immediately become rQJ, and thereafter, calls will not be generated until all other outgoing line groups become "0", so the generation of calls will be time-dependent. In the second example, calls are generated in a concentrated manner for each outgoing line group.In either method, there is a problem in that the calls for each outgoing line group are not random. .

An object of the present invention is to provide an outgoing line group selection method that allocates calls to each outgoing line group according to a predetermined distribution rate, and at the same time, generates calls for all outgoing line groups at random. be.

[Means to solve the problem]

The outgoing line group selection method of the present invention is an outgoing line group selection method for a transit exchange that has a plurality of outgoing line groups on the same route. An allocation rate registration chifur, a random number table corresponding to a unit for specifying the allocation rate of the call, and at the same time as registering the allocation rate of the call, refer to the random number table to select the outgoing line group for the plurality of outgoing line groups. This configuration includes an outgoing line group selection order table that determines the order and registers the result.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a connection diagram of a group of outgoing lines for explaining one embodiment of the present invention.

The exchange 1 in country A includes outgoing line groups 5 and 6.7, which connect to the exchanges 2 and 3.4 in country B, respectively, and outgoing line group 9, which connects to the exchange 8 in country 0. Regarding the allocation of calls from country A to country B, discussions have already taken place among the three telecommunications carriers in the eight countries, with 60%, 30%, and 10% allocated to exchanges 2 and 3.4, respectively. It is assumed that the amount is to be distributed. Regarding calls from country A to country 0, since there is only one telecommunications carrier in country C, there is only one outgoing line tf9.

FIG. 2 is a flowchart showing the table configuration and the flow of information therebetween according to an embodiment of the present invention.

In a call distribution rate registration table 10 that registers call distribution rates specified for each of a plurality of outgoing line groups, allocation rates determined in correspondence with outgoing line group numbers are registered. Random number table 11 is
The unit for specifying the call allocation rate (in this example, 1
%), the whole is set as 100, and the range is 1 to 100.
It is a sequence of random numbers up to . The outgoing line group selection order table 12 is configured to allocate each outgoing line group in the allocation rate registration table 10 into groups according to the distribution ratio, starting from the first random number in the random number table 11, and then to create groups based on the random numbers. They are rearranged in ascending order of numbers. The state of change during that time is expressed like a flow chart.

The outgoing line group selection order table 12 is created every time the call distribution rate registration table 10 and the unit for specifying the call distribution rate are specified, and is always kept as the latest information.

Next, a method of using this outgoing line group selection order full 12 will be explained.

When the first call occurs, the exchange 1 reads the outgoing group number paired with the random number number 1 from the outgoing group selection order table 12, and transfers the call to the line of the specified outgoing group. Connect. At the same time, the random number number 2 is specified to know the outgoing line group to be used next. In the following order, each time a call is made, the random number is incremented by 1 and the outgoing line group is designated.

When the random number reaches 100, it returns to random number 1 again.
Repeat specification.

By doing this, if there are 100 calls, the outgoing line group that received a 60% allocation rate will receive 60 of the 100 calls.
calls are distributed, and the occurrence of those calls is random.

〔Effect of the invention〕

As explained above, the present invention has the effect of allocating calls to each outgoing line group according to a predetermined distribution rate, and at the same time, making it possible to randomly generate calls for all outgoing line groups.
