2 is a diagram for explaining a connection relationship between a circuit management apparatus and a switch according to the present invention, and FIG. 3 is a detailed configuration diagram of the circuit management apparatus shown in FIG.

First, as shown in Fig. 2, the line management device 20 of the present invention is connected to the MPs 140-1 to 140-x of each exchange, collecting line information for each MP of each exchange, If there is a request for expansion or reduction, select an MP to extend or reduce the line. In addition, when the operator wants to read the line information for each MP, it converts it to a format that can be output and displays it.

A detailed description with reference to FIG. 3 is as follows.

The circuit management apparatus 20 according to the present invention includes an interface 220 for performing protocol conversion for transmitting and receiving data and / or control signals with a control unit 210, an exchange, or an external access terminal for controlling overall operations, and MP information for each exchange. And a database 230 in which line information for each MP is stored, an exchange manager 240 for collecting and storing MP information for each exchange at a specified cycle, and collecting and storing line information for each MP at a specified cycle. The line information collection unit 250 stored in the database 230, an increase / decrease processing unit 260 for selecting an optimal MP to increase or decrease a line according to a line extension or reduction request of an operator, and the operator to select line information for each MP. The data processing unit 270 converts the line status information for each MP into a format that can be output as requested.

More specifically, the information collected by the exchange manager 240 and the circuit information collector 250 may be managed as shown in FIG. 4, for example.

4 is a view for explaining management information for each switch managed by the line management device of the present invention.

As shown in the drawing, each exchange ID collects and stores an incoming / outgoing call point, an originating call company, an originating call route, and an incoming call route name. In addition, it collects and stores available lines, unavailable lines, idle lines (idle ports), load rates, and total number of lines for each MP ID included in each exchange. Here, an available line means a line currently in use, and an unavailable line means a line that is not available. In addition, the idle line is available but is currently in use, and the load factor refers to the processing capacity of each MP. And, the total number of lines means the total number of lines assigned to each exchange.

On the other hand, when the operator requests the line extension or reduction for a specific exchange, the increase / decrease processing unit 260 considers the load and resource utilization of the exchange by referring to line information (available line, idle line) for each MP of the exchange. By adding or reducing circuits, the basic principle is to select additional MPs with the most free ports and to add additional circuits.

However, if additional lines are added or reduced only by considering the number of spare ports, load may be concentrated on a specific port. Therefore, each MP may be expanded or reduced by considering the number of lines to be added or reduced and the current port usage status of each MP. It is preferable to distribute the number of reduced lines, and a detailed method thereof will be described later.

5 is a flowchart illustrating a line management method according to the present invention.

For each exchange, in a state in which line information of each MP included in each exchange is collected (S10), and when a specific event occurs by an operator (S20), the controller 210 adds the corresponding event to a specific exchange. Determine whether it is a request event or a reduction request event.

Then, in the case of an extension request event, the expansion algorithm is performed by the increase / decrease processing unit 260 to select a line from an optimal MP (S30), and in the case of the reduction request event, the reduction algorithm is performed by the increase / decrease processing unit 260. It is to be performed to select the line from the optimal MP (S40).

6 is a detailed flowchart of the line extension algorithm shown in FIG. 5.

First, the increase / decrease processing unit 260 receives the number of extension lines input by the operator (S301), and checks whether the number of extension lines received is greater than the total number of MPs of the corresponding exchange (S303).

As a result of checking in step S303, if the number of extension lines is larger than the total number of MPs, it is checked whether the number of extension lines is larger than a preset reference value (S305). Here, the reference value is preferably set to twice the average number of available lines for all the MPs.

As a result of the check in step S305, if the number of extension lines is larger than the reference value, it is checked whether the number of extension lines is at least the number of available lines of the MP with the minimum number of available lines (S307), and the number of extension lines is larger than the number of available lines of the MP with the minimum number of available lines. In the case where the number of available lines is the minimum number of available lines, the line is expanded to the MP with the largest number of idle ports (S309), and it is checked whether there are remaining lines to be added (S311).

If the line to be extended remains as a result of checking in step S311, the process returns to step S303, and if not, the extension algorithm is terminated.

On the other hand, as a result of checking in step S305, when the number of extension lines is less than or equal to the reference value, it is checked whether there are a plurality of MPs with the minimum number of available lines (S313), and when there are a plurality of MPs with the minimum number of available lines, and the confirmation result of step S307 is expanded. If the number of lines is less than the number of available lines of the MP with the minimum number of available lines, the number of idle ports of each MP is checked, and lines are added to the MP with the largest number of idle ports (S315).

In addition, when the number of lines to be added is less than or equal to the total number of MPs, as a result of checking in step S303, it is checked whether there are a plurality of MPs having the minimum number of available lines (S317). When there are a plurality of MPs with the minimum number of available lines, a line is added to an MP with the largest number of idle lines among the MPs with the minimum number of available lines (S319).

If there is only one MP with the minimum number of available lines as a result of checking in step S319, and if there is only one MP with the minimum number of available lines as a result of checking in step S313, the MP, that is, one MP with the minimum number of available lines is present. The line is expanded (S321).

FIG. 7 is a detailed flowchart of the line reduction algorithm shown in FIG. 5.

First, the increase / decrease processing unit 260 receives the number of reduced lines input by the operator (S401), and checks whether the number of received reduced lines is less than the total number of MPs of the corresponding exchange (S403).

As a result of the check, if the number of reduced lines is less than the total number of MPs, the number of available lines of the MP having the minimum available line is less than or equal to the number of reduced lines (S405). In step S407, a plurality of MPs having the least idle ports are present.

When there are a plurality of MPs having the minimum idle port as a result of checking in step S407, one line is reduced for each MP having the minimum idle port (S409), and the line to be reduced still exists (S411) to be reduced. If the line remains, the process returns to step S403; otherwise, the reduction algorithm ends.

On the other hand, if the number of available lines is more than the total number of MPs as a result of the check in step S403, and if the number of available lines of the MP with the minimum number of available lines is greater than the number of reduced lines, the MP with the most available lines is Check whether there is a plurality (S415).

As a result of checking in step S415, if there is only one MP with the most available lines, or if there is only one MP with the lowest idle port as a result of checking in step S407, the MP idle port with the most available lines is the minimum. The line is reduced in the MP (S413).

In addition, when there are a plurality of MPs with the most available lines as a result of checking in step S412, the line is reduced from the MP with the least idle port among the MPs with the most available lines (S417).

In the above, a preferred embodiment of the line extension and reduction method has been described. If the line extension and reduction method adds a line to the MP having the largest idle port and reduces the line to the MP with the minimum idle port, It can be changed in any form.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

According to the present invention, the circuit information of the exchange is collected in real time, and when the circuit expansion or reduction is necessary, the idle port allocated to each main processor provided in each exchange is checked, and the circuit is expanded to the main processor having the largest idle port. By reducing the line from the MP with the least idle port, it is possible to prevent load concentration on a specific main processor and to allocate resources efficiently.
