In recent, the rapid convergence of telecommunication and broadcasting has been considered as one of the hot issues in the IT industry. This convergence will provide telecom operators with both opportunities and threatens. This is because that telecom operators can enter the broadcasting industry, whereas broadcasters will also have a chance to provide telecom services. This work aims to discuss the business strategy for telecom operators to provide a TV VOD service, one of the convergence services between telecommunication and broadcasting, through the high-speed internet which is so much served in Korea. It seems that this service will achieve two business goals, namely "to minimise an additional investment" and "to find out a new benefit source", by fully utilising a current high-speed internet infrastructure. Finally, this paper mainly contains the market overview of in telecom and broadcasting service, the definition of TV VOD service and the necessity for this service, a market forecasting and the provision strategy of major telecom operators, and key success factors and a benefit model.

Due to the convergence of voice, data, and video, today's telecom operators are facing the complexity of service and network management to offer differentiated value-added services that meet customer expectations. Without the operations support of well-developed Business Support System/Operations Support System (BSS/OSS), it is difficult to timely and effectively provide competitive services upon customer request. In this paper, a suite of NGOSS-based Telecom OSS (TOSS) is developed for the support of fulfillment and assurance operations of telecom services and IT services. Four OSS groups, TOSS-P (intelligent service provisioning), TOSS-N (integrated large-scale network management), TOSS-T (trouble handling and resolution), and TOSS-Q (end-to-end service quality management), are organized and integrated following the standard telecom operation processes (i.e., eTOM). We use IPTV and IP-VPN operation scenarios to show how these OSS groups co-work to support daily business operations with the benefits of cost reduction and revenue acceleration.

Purpose - This research primarily assesses interactive quality in the service encounters of Ethiopian Telecom from the customer and contact personnel perspectives. Research design, data, and methodology - After reviewing the literature on service encounters and interactive quality, two separate questionnaires and structured personal interviews were conducted to collect the opinions of 400 customers and 100 employees of Ethiopian Telecom. The researchers used convenience sampling; the responses, measured on a five-point Likert-type scale, were analyzed through chi-square tests conducted on SPSS 17.0. Results - Regarding the outcome expected by customers, encounter effectiveness is very low. Regarding accessibility and materiality, the corporation's personnel are freely accessible, relatively well-dressed, and have access to sophisticated office equipment and physical facilities. Finally, with regard to agent satisfaction, the telecom's contact employees are shown to gain little professional satisfaction from service encounters. Conclusion - The study clearly presents the areas in which interactive quality strongly affects both telecom customers and employees; this will help the corporation take corrective action. This is of utmost contemporary importance for both practitioners and researchers.

To compensate the loss of leased-line subscribers and the excessive increase of residential xDSL (Digital Subscriber Line) ones of KT (Korea Telecom), the paper proposes the service model by which it can reinstate the subscription ratio status through employing next generation OSS (Operations Support System) and highquality MPLS (Multiprotocol Label Switching) VPN (Virtual Private Network). It also describes diverse modules comprising NeOSS (New OSS) of KT, followed by detailed accounts regarding the service delivery process of KT VPN. Shortly visited are the primary constituents as well as configuration parameters of MPLS VPN. Finally the network topology along with a feasible service model case is presented.

We study factors that affect consumers' switching behaviors among service providers in Korean mobile telecommunications service market. For empirical analysis, quarterly time series data from the first quarter of 2004 through the second quarter of 2007 were used. We chose the number of switchers to each mobile service provider in each quarter as dependent variables. Independent variables include acquisition costs per subscriber, which play the role of subsidy to mobile handset, switching costs, time trend, structural change effect, and waiting demand effects. Through the empirical analysis, we found that each provider's churn-in customers are affected by different factors. Specifically, the number of churn-in customers into SK Telecom is explained mainly by SK Telecom's customer acquisition costs and waiting demand from KTF, while the number of customers switching into KTF is better explained by switching costs from the previous service provider and waiting demand from SK Telecom. Those who chose LG Telecom as their new provider, on the other hand, were mainly attracted by LG Telecom's high subscriber acquisition cost.

통신기술의 발달에 따라 기존의 통신망은 TP 기반의 NGN 구조로 통합이 추진되고 있으며, 서비스 형태도 음성주도형 서비스에서 음성과 데이터가 혼합된 멀티미디어형 서비스로 전환되는 추세이다. 또한 기존 PSTN 서비스를 인터넷기반으로 대체하는 인터넷전화 서비스가 출현하게 되었다. 인터넷전화 서비스는 VoIP 관련 번호 제도가 체계적으로 도입되고 사업자 역무가 구체화될 경우 본격적인 활성화 단계에 진입할 것으로 예상된다. 기업측면에서는 통신 요금을 절감하고 음성과 데이터를 통합하여 사용할 수 있는 사설망 구축을 적극적으로 도입하거나 활용을 검토하고 있는 추세이며 개인 고객들도 향후 IP 기반의 유무선 인터넷전화 서비스를 많이 활용하게 될 것이다. 결국 ITSP와 사설기업망이 많이 생겨나게 되고, 이러한 환경에서는 ITSP(Internet Telephony Service Provider)와 사설 기업망 가입자들은 모든 타사업자 (ITSP, 무선통신사업자. PSTN 사업자, 사설 기업망 등)들간 통신을 위하여 협약을 체결하고, 호 라우팅을 위한 정보를 유지하고 과금 정산 기능을 지원하여야 하는 문제점이 있다. 이를 위한 방안으로서 사업자간 정산 시스템을 중심으로 ITSP와 사설기업망 가입자를 연동하도록 구성할 수 있다. 프로토콜로서는 ETSI 표준 프로토콜 OSP을 사용하도록 한다. 본 고에서는 사업자간 정산 시스템(OSPs : OSP 서버)을 통한 ITSP와 사설 VoIP 망들간의 호 서비스 연동 방안을 제시하였다.

The telecommunication service industry plays a major role in the realization of the perfect information society in the 21st century and, has a great influence in society and culture. Using the Calculable General Equilibrium Model, we analyze the telecommunication service's economic effects on other industries as well as on the national economy. In 2001, the 8 percent increase in the telecom sales caused the 5 billion dollar increase in the GDP, which seems to continue to bring about no less than 5 billion dollar GDP increase each year until 2030. The telecom sales increase has been evaluated to have disproportionately positive effect on transmission device and audio equipment industries. In summary, the telecom sales have a positive net enぉ on the GDP and on most of the industries with a few exceptions.

In this paper, we describe ubiquitous environments and the trend of convergence that is an evolution path of. current telecommunication, and show the concept of broadband convergence network, service feature and evolution path. In order to converge wire and wireless communication, telecommunication and broadcasting, voice and data efficiently, broadband convergence network divides a network into service layer, control layer, transport layer, ubiquitous access and terminal layer. Broadband convergence network will be a network that can provide and control broadband multimedia services with QoS and security of different and customized level. Then we depict characteristics and types of broadband multimedia service, and describe the characteristic of broadband convergence network. Finally, we show ubiquitous network based on the broadband convert- gence network to provide ubiquitous service which is a future telecommunication service. We also describe requirements of ubiquitous network such as an intelligent and context based platform, convergence terminals, ubi- quitous computing devices, etc.

Marketing is said to be a zero sum game i.e. each gain of customer for a firm is always at the expense of some other firm's customers. Therefore in a marketplace churn is a natural occurrence. Churn in Indian telecom market is among the highest in growing telecom markets. By using binary logistics regression analysis based models based covering a sample of 822 Indian telecom subscribers; this paper attempts to examine the determinants of churn. The future churn is found to be dependent on satisfaction level of the customer with the service provider, attitude and loyalty of the customer variables, intended churn (i.e. intention to churn) and current loyalty (defined as intention to recommend) and distraction (i.e. intention to experiment).
