고품질 콘텐츠 제공환경하에서 인터넷 접속료 책정방안

정충영(Choong-Young Jung) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.11

본 연구는 콘텐츠 제공자들이 자사의 콘텐츠를 보다 저렴한 비용과 높은 품질로 제공하기 위하여 이용자들이 가입되어 있는 ISP에게 직접 접속할 수 있는 다양한 기술을 적용할 경우, ISP들이 CP와 인터넷 가입자에게 망 혼잡에 따른 추가적인 접속료를 부과할 수 있다는 모형을 설정하고 분석한다. 이 경우 CP의 시장상황에 따라 ISP가 책정하는 접속료의 수준은 많이 달라질 것이다. CP가 경쟁적인 경우에는 이부제 요금을 적용하고 있는 ISP간 경쟁하에서 접속료는 CP요금과 함께 사회적 최적 상태와 동일하게 결정될 것이지만 CP가 독점적일 경우 ISP는 접속료에 대한 CP 요금 민감도에 따라 접속료 수준을 다르게 책정할 가능성이 있다. CP가 독점적인 경우 규제를 통해 사회후생의 왜곡을 치유할 수 있는데, 사회적 최적 접속료는 CP가 경쟁적인 경우보다 낮은 수준이다. 이는 CP가 독점적이므로 규제에 의해 접속료가 결정되면 그 접속료를 기반으로 CP가 한계비용보다 큰 요금을 결정하기 때문에 규제자는 접속료를 CP가 경쟁적일 때보다 낮게 책정하는 것이 사회후생을 더 증가시키게 된다. This paper analyzes internet access model between ISP, CP and end users where CP uses various technologies to provide direct access to ISP owning subscribers to consume its own contents in low cost and high quality. The level of access charge depends on the competitiveness of CP market. When CP market is perfect competitive, the level of access charge is identical to that of social optimum while when CP market is monopoly, the level of access charge is influenced by the sensitivity of the contents price to access charge for CP. The dead weight loss due to monopoly market in CP can be removed by the regulation of access charge. Socially optimal access charge in monopoly market of CP is lower than that in competitive market. This is because the regulator wants to set access price to lower level to reduce welfare loss from monopoly in CP market where CP determines the price to over marginal cost.

강지혜(Jihye Kang),최진석(Jin-Seok Choi),이주연(Ju-Yeon Lee) 한국철도학회 2015 한국철도학회 학술발표대회논문집 Vol.2015 No.10

2004년 철도구조개혁 기본계획에 따라 철도부문의 상하분리가 이루어졌으며, 철도운영자는 철도시설관리자에게 시설 이용에 대한 일정한 대가를 지불하고 있다. 현재 철도시설 중 선로는 선로 등의 사용계약을 통해 사용료를 지불하는 한편, 역사 및 차량기지는 국유재산무상사용 허가를 통해 사용권을 부여하는 방식의 이원화된 체계로 운영되고 있어 논란이 가중되어 왔다. 이에 지난 2014년 9월 철도산업위원회는 철도시설 계약대상의 불일치 및 경쟁운영체제에 부적합한 현 체계의 문제점을 해결하기 위해 철도시설 관리 및 사용체계 개편방안을 의결하였으며, 이에 따라 기존의 이원화된 사용체계를 선로 및 역시설에 대한 사용계약으로 일원화하는 방안이 추진 중이다. 이에 본 논문은 역 시설에 대한 사용계약 대상을 분류 · 규정하고 역 시설 건설비용과 이용수요를 고려하여 합리적인 사용료 산정을 위한 방안을 제안하였다.

These charge and permission system have a problem such as the conflict between facility authority and railway operator. To solve this problem the permission for use of railway change into station Station access charge. This study suggest reasonable station access charge Estimation.

A Note on the Interconnection Charge Discount

Kim, Tae-Sung 충북대학교 산업경영연구소 2002 産業과 經營 Vol.15 No.1

In this paper, we present a method for determining a reasonable discount rate for an interconnection charge by estimating additional delay clue to ' unequal access.' Costs derived from unequal access are mainly due to longer dialing time and PDD(Post Dialng Delay), low call complaetion rate, and unfair business. A composite measure which represents the delay derived from unfair access is obtained by analyzing a loss model and considering appropriate additional delay to lost calls. The measure can be presented as a lower bound for the network charge discount rate. We hope our work will shed light on negotiating access charge between an incumbent and entrants and establishing an interconnection regime.

법무보험의 면·부책 사례에 따른 비교법적 연구 — 독일의 2009년 보험계약법(VVG)을 중심으로 —

권효상 한국경영법률학회 2010 經營法律 Vol.21 No.1

There are a few points at issue in the legal cases of Legal Affairs Insurance(here in after LAI) in Korea. Under article 720 of the Commercial Act, the insured is entitled to be compensated for the defending charges. Under article 680 of the Commercial Act, the insured is imposed to sue and labour in order to avert and minimize the loss caused by the accident. If the accident under those article of the Commercial Act occurred, the insurer must pay the charges to the insured, even if the total sum of the defending costs and the indemnity(the charges of loss prevention) is in excess of the sum insured. But, as the legal nature of those article have two or more faces, everything turns on the judge's interpretation of the law. For the refrain from the lack of coverage under the judge's interpretation of the law, we can imagine one of the alternatives is LAI contract in Korea. If the insured didn't compensated by liability insurance because of the lack of coverage under the judge's interpretation of the law, the insured would be compensated by LAI contract. And, for bring in a bill to improve the circumstance of LAI contract, we should referred to German law(Versicherungsvertragsgesetz -VVG) that is very delicate legal structure about LAI contract that is regulated and separated from other line of insurance contract law.

김상균,원종석,편용범,조민경 한국재난정보학회 2024 한국재난정보학회 논문집 Vol.20 No.2

연구목적: 이 연구는 서울시 10개 수소충전소의 공간적 접근성 분석을 실시하고, 접근이 어려운 지역을 식 별하였다. 입지의 형평성과 안전성 측면에서 신규 입지를 추가하여 접근성을 분석을 다시 수행한 후, 개선 효과 비교를 통해 시사점을 도출하는 것을 목적으로 한다. 연구방법: ArcGIS 프로그램의 네트워크 분석 기 반의 입지배분(Location-Allocation) 모형과 이용권역(Service Area) 모형을 적용하여 접근이 취약한 지역 을 식별하였다. 입지선정 방분석 기반의 입지배분(Location-Allocation) 모형과 이용권역(Service Area) 모 형을 적용하여 접근이 취약한 지역을 식별하였다. 입지선정 방법은 부족한 수소충전소에 신속한 도착이 필요한 점을 고려하여 ‘최소시설 수로 최대수요를 확보하도록 함(Minimize Facilities)’ 방법을 적용하였다. 특정한 시간 내의 도착을 위한 한계 거리는 서울시 2022년 평균 차량통행속도(23.1km/h, 서울시 열린데이 터 광장)를 적용하여 10분 이동가능 거리인 3,850m과 5,775m(15분) 그리고 7,700m(20분)의 세 가지로 분하여 분석하였다. 신규 입지는 수소충전소 설치에 대한 갈등을 최소화하기 위하여 산업통상자원부의 특례기준1)을 적용하여 기존의 주유소, LPG/CNG 충전소 중에서 수소충전소 추가 설치가 가능한 후보지를 도출하였다. 연구결과: 분석 결과, 최종적으로 상세 현황 검토를 통해 추가 후보지 5개소가 도출되었다. 기존 10개의 수소충전소에 20분 이내 접근이 취약한 지역을 중심으로 상대적으로 안전한 기존 주유소와 LPG/CNG 충전소에 신규 수소충전소 5개소를 설치하면 접근성이 크게 개선됨을 확인할 수 있었다. 그럼에도 불구하고 여전히 접근이 어려운 지역이 있는 것으로 나타났다. 결론: 입지배분모형을 이용하여 수소충전소 접근이 어려운 지역을 식별하고, 설치의 우선순위를 부여한다면 과학적 근거 기반 수소충전소 입지 선정을 위한 의사결정을 지원할 수 있다. Purpose: This study analyzes accessibility of 10 hydrogen charging stations in Seoul and identifies areas that were difficult to access. The purpose is to re-analyze accessibility by adding a new location in terms of equity and safety of location placement, and then draw implications by comparing the improvement effects. Method: By applying the location-allocation model and the service area model based on network analysis of the ArcGIS program, areas with weak access were identified. The location selection method applied the 'Minimize Facilities' method in consideration of the need for rapid arrival to insufficient hydrogen charging stations. The limit distance for arrival within a specific time was analyzed by applying the average vehicle traffic speed(23.1km/h, Seoul Open Data Square) in 2022 to three categories: 3,850m(10minutes), 5,775m(15minutes), 7,700m(20minutes). In order to minimize conflicts over the installation of hydrogen charging stations, special standards of the Ministry of Trade, Industry and Energy applied to derive candidate sites for additional installation of hydrogen charging stations among existing gas stations and LPG/CNG charging stations. Result: As a result of the analysis, it was confirmed that accessibility was significantly improved by installing 5 new hydrogen charging stations at relatively safe gas stations and LPG/CNG charging stations in areas where access to the existing 10 hydrogen charging stations is weak within 20 minutes. Nevertheless, it was found that there are still areas where access remains difficult. Conclusion: The location allocation model is used to identify areas where access to hydrogen charging stations is difficult and prioritize installation, decision-making to select locations for hydrogen charging stations based on scientific evidence can be supported.

Network Effects and Incentive to Attract Competition

김종민(Chongmin Kim),왕규호(Gyu Ho Wang) 한국계량경제학회 2005 JOURNAL OF ECONOMIC THEORY AND ECONOMETRICS Vol.16 No.1

본 논문은 망외부성이 존재할 경우, 기존 기업이 자신이 가지고 있는 필수설비를 잠재적 경쟁기업에게 제공할 유인을 분석하고 있다. 망외부성이 없으면 기존 기업은 접속료를 매우 높이 책정하여 진입을 봉쇄할 유인을 가진다. 반면에 망외부성이 존재하면, 기존 기업은 진입을 촉진할 유인을 가진다. 또한 진입 비용이 존재할 경우, 기존 기업은 접속료를 낮게 책정하여 진입 기업에게 암묵적으로 보조금을 지불하고자 하는 유인을 가진다. 마지막으로 망외부성이 증가하면, 접속료의 크기는 한계비용으로 수렴한다. In this paper, we study the incumbent’s incentives to share its essential facility when there exist network effects. We show that without network effects, the incumbent will charge the access fee high enough to deter the entrant. With network effects, however, the incumbent always has an incentive to attract competition. We also show that if the potential entrant has to pay the entry costs, then the incumbent has an incentive to subsidize the entrant with a low access charge. When the network effects become large, the incumbent is willing to lower the access fee to the marginal cost.

FSO as backhaul and energizer for drone-assisted mobile access networks

Nirwan Ansari,Di Wu,Xiang Sun 한국통신학회 2020 ICT Express Vol.6 No.2

Drone mounted base stations (DBSs) can be flexibly deployed over some areas (such as hotspots and disaster struck areas) to speed up the communication between terrestrial base stations (TBSs) and users. In order to increase the capacity of the backhaul link between a DBS and its TBS, free space optical (FSO) communications is applied as the backhaul solution. However, the DBS and its TBS should be in line-of-sight (LoS). Thus, a new DBS placement method is introduced to maximize the number of served users while guaranteeing the LoS between the DBS and its TBS. In addition, in order to prolong the hovering time of a DBS, we propose to deploy an optical beam to facilitate simultaneous communications and charging. That is, an optical beam transmitted from a TBS to its DBS carries not only data but also energy. The DBS mounted with a solar panel and an FSO receiver receives both the data and energy carried by the optical beam simultaneously. Numerical results demonstrate that using an optical beam to charge and communicate with a DBS can gain 25% extra hovering time of the DBS and achieve high network throughput.

Due to rapid developments of IT technologies, convergence services like IPTV (Internet protocol television) are shown up. Even though expert and customer had great expectations for this innovative service, commercialization was delayed for years by the legal dispute between industry players. One of the biggest problems was that whether internet backbone providers have to share their internet network backbone with IPTV service providers (which don’t have network backbone) or not. As other countries, Korean government set the rules that ISP have to offer indiscriminate access to other IPTV service provider. At the same time, internet backbone providers can charge access charge based on cost by way of compensation. Thus access charge is very critical to the IPTV industry players. The objective of this paper is to provide model that can calculate the reasonable access charge by system dynamics, based upon real data in Korean telecommunication industry.

Determination of the Optimal Access Charge for the Mobile Virtual Network Operator System

김병운,Sung Uk Park 한국전자통신연구원 2004 ETRI Journal Vol.26 No.6

ABSTRACT⎯The introduction of a mobile virtual network operator (MVNO) system is expected to increase consumer benefits, boost competition in the mobile market, utilize idle bandwidth, and expedite mobile-fixed line convergence and growth in the mobile Internet market. This research endeavors to study the optimal access charge for an MVNO system, which is expected to be introduced to the Korean mobile communications market. We found that the optimal access charge is higher in the interdependent model than in the independent model if demand for mobile phone service is based on a substitution relationship. We also found that the optimal access charge is higher than the marginal cost.
