Facility cost calculation system and method for each communication service {SYSTEM AND METHOD FOR CALCULATING THE COST OF EQUIPMENT EACH SERVICE}

The present invention relates to a system cost calculation system and method for each communication service, and more particularly, a communication facility that is used redundantly to provide various communication services such as a public switched telephone network (PSTN) phone, the Internet, an Internet phone, an Internet TV, and the like. The present invention relates to a facility cost calculation system and method for each communication service that can calculate accurate facility costs even in an environment in which there exists.

The telecommunications industry is a large-scale equipment industry, and at the same time, has a characteristic of providing service products directly to end consumers. Therefore, there are the following features in terms of equipment cost of the telecommunications industry.

First, the telecom industry has a large share of equipment costs. Second, due to the emergence of various convergence / combination services that use telecommunications facilities in common, the indirect cost is higher than the direct cost. In other words, the indirect cost is large due to a general-purpose facility such as Multi Service Provisioning Platform (MSPP) that can transmit / process various types of services such as PSTN (TDM), Internet, and leased line through one optical transmission equipment. Third, since network equipment is composed of a complicated layer (OSI 7 Layer) to provide one communication service, there is a limit in estimating the cost by a simple allocation method.

Such telecommunications industry has a large proportion of equipment costs among the total costs, and despite the importance of equipment cost information, accurate cost estimation is difficult due to the above-mentioned characteristics.

Conventional equipment cost calculation is by simply assigning the cost of the equipment after creating a service product using the equipment for each equipment. There is a problem that can not calculate the equipment cost.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, It can be easily carried out. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. 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 a facility cost calculation system for each communication service according to the present invention.

As shown in FIG. 1, the facility cost calculation system for each communication service according to the present invention includes basic data collection including a depreciation cost collector 11, a cost list generator 12, and a basic information collector 13. The apparatus 10 includes an apparatus cost calculating device 20 having a block generating unit 21, a distribution processing unit 22, and a cost calculating unit 23.

Here, the basic data collection device 10 collects the cost of each group by grouping the same type of equipment and then summing the depreciation cost of each equipment in the group.

The facility cost calculator 20 classifies each group into hierarchical blocks according to function, hierarchy, use / service / media, and calculates the distribution ratio between hierarchical blocks based on cost driver information to calculate facility costs for each service. Calculate.

Hereinafter, the detailed components of the basic data collection device 10 will be described.

First, the depreciation cost collecting unit 11 calculates the cost of the communication equipment as the depreciation cost among various cost factors such as labor cost, marketing cost, repair maintenance cost, expense, depreciation cost, etc.

Depreciation means depreciation of an asset over time, and from an accounting perspective, depreciation is the process of distributing the value of an acquired asset as a cost over its useful life. Therefore, rather than calculating all costs in the year of purchase and construction of a telecommunications facility, the acquisition cost of the facility is calculated by allocating it during the period of use. Depreciation cost calculation methods include fixed-rate, fixed-rate, water supply, and output-proportional methods.

The telecommunications facility, which is a fixed asset of a telecommunications company, is registered in the fixed asset management system (ERP_FA) on a construction basis at the time of initial construction after purchase, and asset management begins. Since it is calculating, the depreciation cost collection part 11 collects depreciation cost in connection with a fixed asset management system.

On the other hand, the fixed asset management system manages assets on a construction basis, and therefore manages a list of fixed assets such as hundreds of thousands of equipment, tracks, and servers in the fixed asset account book. Therefore, the fixed asset list is too large to calculate costs, and needs to be grouped into hundreds of network asset groups, grouped in units suitable for cost distribution.

Therefore, the cost list generating unit 12 generates a Cost Object Pool (COP), which is the basis for calculating network equipment costs by tying equipment of the same type from the asset book of the fixed asset management system.

That is, the cost list generation unit 12 combines equipment of the same type, for example, various types of tracks into an item of 'track', calculates the cost for the 'track' by adding the depreciation cost of each track, and matches them. Create a list of recorded costs. This list of costs includes information on all telecommunications facilities, such as exchanges, transmissions, power sources, as well as lines.

In addition, the cost list generation unit 12 easily classifies the cost list in various perspectives and assigns an asset classification code to easily calculate equipment costs for each service.

As shown in FIG. 2, the asset classification code system is largely classified into a layer (layer), a function, a hierarchy, a use / service / medium, and a collection structure. BB1), telecommunication equipment (BB2) classified according to hierarchy, telecommunication equipment (BB3) classified according to use / service / media, and service (Commercial Product). It is classified into the functions of seven areas such as exchange, transmission, server, line, power, and others.In terms of hierarchy, it is classified into six classes, such as subscriber, downtown, intercity, international, intracity, and core. Are classified into TYPE1 and TYPE2 according to the equipment supporting a specific service or the joint equipment supporting various services.

The asset classification code system can be used to classify and aggregate costs from a multidimensional perspective. For example, the cost of the power sector may add up the costs of all the codes with 'AB' value of 'PW', and the cost of the line sector should sum all the costs of the code with 'AB' value of 'LN'. .

In addition, the '789' value of the asset classification code is a service-related code, and the VoIP-related service cost can be obtained by summing all codes having a '789' value of '326'. In addition, the code in which both function and hierarchy are summed into one service shows 'ABC' as 'ZZZ' so that it can be easily identified as the sum of one service. For example, a code that adds all functions and ranks to a VoIP service has a value of 'ABC789' as 'ZZZ326'.

On the other hand, the cost is distributed to BB1, BBk, BB3, etc. step by step to finally calculate the equipment cost for each service, at this time based on the drivers that cause the cost. This is called cost driver, and cost drivers for communication facilities include call number, call volume, number of subscriber lines, equivalent athlete, and traffic volume.

The basic information collecting unit 13 collects cost driver information in association with an operating management system (OSS) and a billing system.

Hereinafter, detailed components of the facility cost calculating device 10 will be described.

In order to allocate the cost of complex network equipment by service, it is necessary to convert the physical equipment into logical communication service. Therefore, in order to accurately allocate the cost of communication facilities by services, we define a logical network component (Building Block, BB), which is similar to Activity, by applying Activity Based Costing (ABC) calculation method. .

Logical network components represent meaningful intermediate cost objects in the process of converting from physical facilities to logical services. The conceptual design for the logical network component is as shown in FIG.

Therefore, the block generation unit 21 classifies the communication facilities on the cost list using the asset classification code into hierarchical blocks according to function, hierarchy, use / service / medium.

Then, the distribution processing unit 22 calculates the distribution ratio between hierarchical blocks based on the cost driver information collected by the basic information collecting unit 13.

That is, as shown in FIG. 4, the amount of calls is distributed as a cost driver when distributing the costs aggregated in a block, which is a logical network component of a city exchange, to a local product, a 114 number guide, a general telephone LM, and a public phone. To distribute the cost of a city exchange to a service based on the percentage of money in each service product.

As shown in FIG. 5, when distributing the costs aggregated into a block, which is a logical network component called the Internet backbone, to an Internet service, a leased line service, etc., each of which uses the Internet backbone, only the number of subscribers is used. Rather, considering the traffic volume, which causes the investment in the Internet backbone, the traffic occupied by one Internet service line is assumed to be 1, and the relative traffic share of each service is multiplied by the number of users.

On the other hand, since telecommunications companies have hundreds of blocks and need to manage and calculate all allocation logic between blocks, manual calculations are inefficient and use databases such as DB and SQL for fast and automated calculation of network equipment costs.

Defining and managing these blocks and cost drivers directly in the SQL language is inconvenient for the user interface, so defining and modifying a large amount of data in Excel and saving them back to SQL DB using SQL Excel, SQL DB Block and cost allocation logic is also converted to Excel for download.

6 is an exemplary view illustrating a process of calculating equipment cost for each communication service according to the present invention.

As shown in FIG. 6, the aggregated amount for each cost list and the distribution ratio between blocks are expressed in a matrix, and then multiplied to calculate facility costs for each communication service.

Here, A, B, C, and D represent the amounts aggregated by cost list, E, F, G, and H represent facility costs for each service, and a, b, c, and d are 0 < satisfies a, b, c, d <1.

Usually, the larger the dimension of the matrix, the less efficient the calculation will be, but the cost allocation logic calculates the actual value because most elements are O and only a few elements are non-O when expressed as a matrix. Doing so greatly improves computational performance when not using matrices.

The present invention additionally includes a web report generating device (30) further analyzes the profitability analysis report that can be analyzed in two dimensions, such as goods and branches (regions), and through comparison between the region / product of various driver information or cost Provide internal benchmarking reports.

For example, we provide a report on the overall profitability of each product, such as ADSL, landline, and leased line, as well as the total profit report for each branch and the product cost report provided for each branch. At this time, the sales data required for profitability analysis utilizes data collected by the basic information collecting unit 13.

In addition, the present invention provides a summary report of driver information derived in the cost estimation process to analyze the efficiency of the network equipment.

In addition, the present invention provides a variety of comparative analysis reports, such as by product / region / equipment to induce continuous facility efficiency. The various cost data required at this time utilizes the data collected by the basic information collecting unit (13).

7 is a diagram illustrating an embodiment of a method for calculating facility cost for each communication service according to the present invention.

As shown in FIG. 7, the communication service is decomposed step by step to classify the building blocks, which are logical network components, in a hierarchical manner. Calculate facility cost by service.

8 is a flowchart illustrating a method for calculating facility cost for each communication service according to the present invention.

First, after grouping equipments of the same type, the depreciation ratios of the equipments in the group are added together to collect the costs for each group (801).

Subsequently, the collected groups are classified into hierarchical blocks, and equipment cost for each service is calculated by calculating a distribution ratio between the hierarchical blocks based on cost driver information (802).

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium may include any type of computer readable recording medium.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
