  • In this paper, we present the DEA (Data Envelopment Analysis) application case study to investigate the regionally distinctive telco management characteristics of the Asia-Pacific countries. This study attempts to exploit the implications of DEA for the assessments of core process capabilities of telcos. Accordingly, we extract input variables of CAPEX (capital expenditure), operating expense, marketing expense, and number of employees, each to reflect the competitiveness of the core processes such as fixed asset utilization, operation & sales efficiency, and white collar productivity. In conjunction with the input variables, the output variables are chosen as EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization), ARPU (Average Revenue per User), and number of subscribers. The computational testing results, conducted with total 37 telcos of the 12 Asia-Pacific countries, are analyzed in various ways to understand the distinctive performance characteristics across the region. The managerial implication captured from this study provides useful insight for using DEA as the international telco management purpose.

  • Due to natural oligopolistic industry characteristics and huge influences on national and home economy, Telco Industry is regarded as a regulated industry. Thus, telco companies, including CATV, prepare not only management accounting reports for internal use but also regulatory accounting reports to be submitted to the regulatory agency. For telco companies, smooth integration of these financial, managerial and regulatory reporting requirements with legacies such as billing system, network operating systems is important to achieve operational efficiency and overall competency. This research studies telco ERP cost module implementation in order to provide theoretical and practical guidance for integrated information system. Especially, case analysis focuses on cost reduction and network costing implementation that involves Building Block Costing methodologies.

  • Relational Database Management Systems have become de facto database model among most developers and users since the inception of Data Science. From IoT devices, sensors, social media and other sources, data is generated in structured, semi-structured and unstructured formats, in huge volumes, thereby the difficulty of data management greatly increases. Organizations that collect large amounts of data are increasingly turning to non relational databases - NoSQL databases. In this paper, through experiments with real field data, we demonstrate that MongoDB, a document-based NoSQL database, is a better alternative for building a Telco Subscriber Data Management System which hitherto is mainly built with Relational Database Management Systems. We compare the existing system in various phases of data flow with our proposed system powered by MongoDB. We show how various workloads at some phases of the existing system were either completely removed or significantly simplified on the new system. Based on experiment results, using MongoDB for managing telco subscriber data turned out to offer performance better than the existing system built with MSSQL Server.

  • 통신서비스의 성패를 좌우하는 다양한 선택의 문제 중 하나는 신규 서비스를 제공하는 데 있어서, 어떤 기술을 도입하고 언제 상용화할 것인가를 결정하는 것이다 이러한 결정에는 서비스를 제공하는데 수반되는 투자와 비용, 시장 규모의 예측, 경쟁사업자 동향, 기존 또는 유사 기술과의 호환성이나 경쟁 관계 등이 고려되어야 하며, 이를 위해 다양한 경제성분석 방법이 활용되어 오고 있다. 그러나, 전통적인 현금흐름할인법의 경우, 현재 획득 가능하거나 추정할 수 있는 데이터를 이용해서 의사결정을 내리는 방식을 취하고 있으며 유연한 사고를 통해 수시로 변화하는 사업환경을 동태적 입장에서 의사결정을 지원할 수 없다는 한계를 지니고 있다. 최근, 이에 대한 대안으로 실물옵션이론을 활용한 경제성분석 방법이 소개되고 있다. 이는 금융옵션의 특성에 기반을 둔 방법으로, 주변 여건의 변화에 대해 유연한 의사결정을 지원할 수 있다는 측면이 통신서비스와 같은 불확실성이 큰 사업환경에 적합한 방법이 될 것으로 판단된다. 이에 본 논문에서는 새롭게 부각되고 있는 무선 LAN 서비스의 제공을 위한 통신 사업자의 서비스 도입 전략을 실물옵션이론을 활용해서 분석해 보고자 한다. 이를 통해, 통신사업자의 관점에서 무선 LAW 서비스의 제공을 추진할 때 가능성이 높은 몇 가지 시나리오에 대한 대응 방안과 유의점에 대해 고찰한다.

  • As the core infrastructure to lead technical innovation for the fourth industrial revolution, economic value and utilizations of radiowaves are increased rapidly. The objectives of this study are to recognize the growing trend of radio stations that transmit information using radiowaves, a limited resource of the country, and to propose developed plans for the radio stations operation system in line with the changing radio technology and use environment. To be specific, the detailed implementation procedures and methods of the system were derived in accordance with the government's plan to convert the complete inspection of radio stations into a SDoC(Self Declaration of Conformity) by the telco. SDoC is a policy that grants autonomy and responsibility for radio waves interference management to existing telecom operator recognized as having radio stations operating capabilities. It has significance in that the function of radio stations inspection, which is a representative technical regulation, is efficiently distributed to the government and the private sector. This study has significance in providing reference for expediting deregulation in the radiowaves management policy.
