e-Market 플레이스에서 타 업체와 차별화하는 가장 중요한 전략적 수단으로 e-Service가 강조되고 있다. 본 고에서는 이러한 e-Business 환경변화와 맥을 같이하여, 서비스 마케팅의 기본 개념이라 할 수 있는 서비스 특성을 살펴보고, 이어 e-Service의 정의와 범위를 알아 본 후, 현재 제기되고 있는 e-Service 운영에 있어서의 몇 가지 전략 유형을 살펴봄으로써 향후 e-Service에 대한 활발한 논의가 이루어지는 단초를 제공하고자 한다.

Purpose - This paper analyzes the effect of the handset subsidy and the Mobile Number Portability subscriber subsidy regulation, which are the main regulation adopted in "Law on the Improvement of the Mobile Terminal Distribution System" (Mobile Terminal Distribution Act), on the social surplus, the consumer surplus and profits of telecommunications carriers. We focus our analysis on whether the service charge competition is stimulated enough so that it can compensate for the loss of subsidies. Research design, data, and methodology - We use simple economic model to assess the impact of the handset subsidy and the Mobile Number Portability subscriber subsidy regulation. Unlike the former researches on this topic, we depart from using Hotelling model, and instead use the switching cost model, which uses switching cost as a parameter of market powers of telecommunications carriers. We also study the effect of the two different regulations when they are adopted both independently and concurrently. Results - If the market powers of telecommunications carriers are over certain threshold, contrary to the regulatory agency's assertion, the service charge competition would not be stimulated enough to compensate for the deduction in the subsidies, and thus the consumer surplus is compromised. Number Portability subsidy, especially, undermines the rival's market power and thus reduces the service charge. On the other hand, the regulations will also increase the profits of telecommunications carriers. However, social surplus is maximized when both of the regulations are present because the regulations reduces the frequency of switching handsets inefficiently. Conclusions - In enacting the Mobile Terminal Distribution Act, the telecommunications regulatory agency asserted that the regulation on subsidies will stimulate service charge competition, and in the long run, enhance the consumer surplus. However, contrary to the regulatory agency's assertion, subsidy regulation, especially the regulation on Number Portability subsidy, reduces consumer surplus. On the other hand, the Mobile Terminal Distribution Act can also increase the profits of telecommunications carriers because it decreases competition among the telecommunications carriers. However, the Mobile Terminal Distribution Act can increase the social surplus because it reduces inefficient switching of handsets.

This paper analyzes how the international callback services affect on the international telecommunications market. We present a simple game-theoretic model to compare the equilibrium outcomes before and after the arrival of callback operator. We find that the callback service arises from the inefficiencies in the national telecommunications market and the accounting rate system between international telecommunications carriers. Also, we identify the conflicting interests among the governments and carriers, by examining how the callback service affects the collection rate, quantities demanded, carrier's profit and social welfare of each country.

This study focuses on the ongoing immersive Giga Media service platform technology developed by the Electronics and Telecommunications Research Institute(ETRI) for various projects of the Giga KOREA Foundation[1] to achieve a smart ICT environment including wireless-based Giga service by 2020. This technology enables an immersive realistic Tele-Experience service that supports immersive real-world interaction as if sharing one's surroundings in a particular location through a high-speed network among remote users. It is expected to contribute greatly to the activation of smart ICT.

In Korea, we witness vivid evidences of changing trend in communication that insist the emergence of new networking architecture. To accommodate the changing trend and to hold current strong position in global IT industry, Korea have launched broadband convergence network (BcN) initiative. BcN vision for Korea is to be the first in the world to realize converged network infrastructure and ubiquitous service environment. In this paper, we have introduced the concept and the vision of BcN with a viewpoint of a new paradigm to prepare future-proof communication environment. And then, we have disclosed BcN research and development (R&D) activities including R&D philosophy, R&D phases, and key technologies required. Also, we have discussed current development issues in three technology branches including service and control technology, unified transport technology, and next-generation access technology.

Recent development of communication technology and evolution of telecommunications services, various needs of users are giving Telecom operators difficulties in discovering new services and its promotion strategies. In addition, at the launching of new services, if carriers does not consider complementary and substitution relationships with competing services or self-encroachment problem with the existing service profitability is reduced or lost in the current market. In this study, by analyzing usage pattern of telecommunications services respect to changes in supply and demand environment, the complementarity/substitutability analysis and systematic analytical framework is proposed. This study proposes approaches to establish mobile operators' business strategies and to identify new services demand.
