METHODO FOR SPREADING AND ACCOMODATING EXCHANGE MODULES TO DISTRIBUTE LOAD APPLIED TO THE EXCHANGE MODULES}

The present invention relates to an exchange module distributed acceptance method for load balancing of an exchanger and a computer-readable recording medium having recorded thereon a program for realizing the above-described method.

With the rapid development of the information and communication field, the physical media of subscriber lines are changing from copper lines to optical lines, from telephone-oriented services to multimedia and value-added services.

The exchange collects and processes subscriber data on a module basis. The module of the exchange means the minimum unit in which the exchange balances the load, and the load balancing of the exchange consists of equalizing the preload during the new construction work and the post load balancing to solve the local overload during the operation of the exchange.

The preload equalization operation is a method of selecting one of the relatively low load modules when the machine number is selected, and the postload equalization operation is solved by exchanging a part of the low load module and the overload module when the load inequality is severe.

In the conventional method of decentralizing exchange module for load balancing of the exchange, when a new service request from the subscriber occurs, the machine number in the low load module is selected in consideration of the load module state of the exchange. When the same subscriber requests a large amount, the value for the existing low load module becomes meaningless, and when selecting a facility, the machine number in the load concentrated module may be selected.

In the case of new buildings or buildings, a new hypothesis is required under the same subscriber name, and the measurement of the load value per module of the exchange is performed on a specific day, so the load value for the same subscriber currently obtained is recalculated in real time. Since this is impossible, there is a problem in that the machine number for the new hypothesis is selected at the exchange which is substantially loaded.

The present invention has been proposed to solve the above problems, by managing the new hypothesis request coming into the same subscriber by setting the weight of each switch type, the type of subscriber and the number of selection criteria of the same module of the subscriber, it is possible to distribute and manage the load of the exchange It is an object of the present invention to provide a method for distributing an exchanger module for load balancing of an exchanger and a computer-readable recording medium recording a program for realizing the method. It can be understood by the description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

In the method of the present invention for achieving the above object, in the switch module distributed acceptance method for load balancing of the switch is applied to the subscriber telephone installation management system, receiving the hypothesis request from the outside, the hypothesis request enters the same subscriber An outer line selection step of selecting an outer line according to whether or not it is a new hypothesis; In order to allocate a port for the hypothetically requested telephone number, the information can be selected according to the weight of each exchange type and subscriber type and the number of selection criteria of the same module for the new hypothesis request of the same subscriber. An extension selection step of selecting an extension by selecting a module; A telephone number opening step of opening a corresponding telephone number for a hypothesis by performing a jumper and a circuit switch operation based on the extension selection; And a notification step of notifying the user of the opening result.

In addition, the present invention, an subscriber line installation management system having a microprocessor, an external line selection function for receiving a hypothesis request from the outside, and selecting the external line according to whether or not the hypothesis request is a new hypothesis coming into the same subscriber; In order to allocate a port for the hypothetically requested telephone number, the information can be selected according to the weight of each exchange type and subscriber type and the number of selection criteria of the same module for the new hypothesis request of the same subscriber. An extension selection function for selecting an extension by selecting a module; A telephone number opening function for opening a telephone number corresponding to a hypothesis by performing a jumper and a circuit switch operation based on the extension selection; And a computer readable recording medium having recorded thereon a program for realizing a notification function of notifying the user of the opening result.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an embodiment of the exchange module distributed accommodation system for load balancing of the exchanger to which the present invention is applied.

As shown in FIG. 1, the switch module distributed accommodation system for load balancing of an exchanger to which the present invention is applied includes a user line requesting a hypothesis and a new line receiving a hypothesis request from the user 10. Receives a request for the construction of a new line from the customer information system 11 and the customer information system, selects an external line and an extension, confirms the opening through an exchange operation, and informs the customer information system 11 of the construction work. The subscriber telephone installation management system 12, the exchange status module-specific status information 13 for storing traffic limit information, subscriber facility information, exchange port information, and traffic information of the exchange, and the exchange 14 are included.

The exchange 14 has a different number of subscribers per module according to its type, and the load group unit of the exchange is shown in the following table.

order Exchanger Load group unit Number of subscribers by load group One  NO1A  Concentrator  32, 64 2  5ESS  Line unit  256, 384, 512 3  AX-10  Line switch module  128 4  TDX1A, B  Subscriber Line Processor  1024 5  TDX10  Access Switching Processor  4096 6  S1240  Network address  128 7  TDX10A  Subscriber Line Processor  8192 8  TDX100  Subscriber Line Processor  32768

In general, when looking at the number of demand subscribers per module of the exchange, it can be seen that the capacity of the subscriber increases as a new exchange. Therefore, the distribution reference value of traffic must be managed separately for each exchange type.

There are two types of subscribers that can be divided into two categories: home and business (for public phones). Even a group of physically connected subscribers does not create a load on the switchboard when the telephone is not used. In the case of business subscribers, it is generally used more than home.

Traffic numbers are displayed as fish, which is 0.053 fish for home and 0.091 fish for business.

If a large number of subscribers issue a new order with the same name, the subscriber's facility will be skewed from the side of the Main Distributed Frame (MDF), which connects the subscriber's facility and the exchange facility to the telephone lab. In this case, the facility number of the exchanger is preferably located in the peripheral position because the facility is selected in the direction of reducing the jumper length of the horizontal board in the main board in the facility management of the subscriber main board. Choosing a facility in a nearby location can cause traffic distribution problems. In particular, a large number of subscribers are likely to be for business, and in the case of an exchange, a large amount of local traffic is generated, which affects the stable operation of the system.

The present invention provides information for storing subscriber names inputted by new hypothesis at one-day intervals in a system that performs one-variable hypothesis work, information for recording information on which a particular subscriber selects a specific module for each exchange type, information on selection of the same subscriber for each exchange type, Routines to determine whether a new subscriber is a new subscriber within a day and the number of subscribers per module are additionally used when the number of the same subscriber is exceeded in the module of the selected exchange port when a new subscriber occurs. Do not select a machine number.

Figure 2 is an exemplary view showing an information table for selecting the distribution of facilities in the exchange module distributed acceptance method according to the present invention. As shown in Figure 2, the information table for selecting the distribution of facilities, telephone number, Subscriber facility information that manages the subscriber's address information, such as address, service type information and facility type code, and termination and transfer subscribers for facility recycling such as phone number, address, service type information and facility type code of termination and transfer subscribers Construction order such as exchange port information, construction order, progress status and facility information that manages the status information of the port of each exchange type such as the port number, status information and port type information of the exchange Such as business process information, exchange type, module unit and traffic information that manages the information of business process status by each and exchange type It includes the same subscriber traffic threshold information used to manage the exchange type modular traffic limits, such as traffic information and exchange type, the module unit and the traffic threshold information for managing the module-specific traffic values of the group.

The operation process of the exchange module distributed accommodation method for load equalization of the exchanger having the structure as described above will be described in detail with reference to FIGS. 3 and 4 as follows.

Figure 3 is an embodiment processing flow diagram for a method for distributed exchange module exchange for load balancing of the exchange according to the present invention.

As shown in FIG. 3, first, the customer management system 11 receives a hypothesis complaint from the user 10 (100), and requests a hypothesis from the subscriber telephone installation management system 12 (110).

Accordingly, the subscriber telephone installation management system 12 receiving the hypothesis request from the customer management system 11 checks whether the hypothesis request is a new hypothesis, selects the external line of the subscriber's house and the main wiring board (120), and installs the facility. An extension for the corresponding external line is selected using the information for the dispersion selection (130).

After determining the position of the main wiring board, registering the new subscriber information with the switch 14, changing the port to an available state (140), and performing a jumper operation and a circuit switch operation (150).

Next, by changing the current status information for each switch module (160), and transmits the opening confirmation and construction order completion notification to the customer management system 11 (170), the customer management system 11 is the user 10 Notify the completion (180).

4 is a detailed flowchart of one embodiment of a subroutine for performing the extension selection in FIG. 3. As shown in FIG. 4, an input telephone number for which a hypothesis is requested is confirmed (131), and a corresponding phone number is shown. After selecting a new module of the exchange (132), the number of the same subscriber of the module is counted (133), and the count is set to the number of the same subscriber of the module (134).

Next, it is determined whether the count exceeds a reference value of the corresponding module (135).

In the determination result 135, if the count exceeds the reference value of the corresponding module, it is determined whether the current module is the last available module (136).

As a result of determination 135, if the count is less than the reference value of the module, the available port in the module is selected as the port of the request input telephone (138).

On the other hand, the determination result 136, if the last module is set to the acceptance limit by adding the set value to the same subscriber acceptance limit of the exchange, and then proceeds to step 135 to determine whether the count exceeds the reference value of the module.

As a result of the determination 136, if not the last module, the process proceeds to a process 132 of selecting a new module of the exchange corresponding to the telephone number.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since the process can be easily carried out by those of ordinary skill in the art to which the present invention pertains, it will not be described in detail any further. The present invention described above is intended to be carried out by those skilled in the art to which the present invention pertains. It is not limited to the above-described embodiment and the accompanying drawings as various substitutions, modifications and changes are possible within the scope without departing from the spirit of the present invention.

The present invention as described above, when the number of the standard number of the exchange is exceeded by selecting the port in the other module, there is an effect that the exchange can be stably operated through load balancing of the exchange.
