As well as the development of the measurement of service quality, various kinds of service measurements are also being developed. Especially the mobile telecommunication service being representative to the mobile telecommunication company would be the mostly developed area. Its development can be understood along with the development of the telecommunication companies as well as cellular companies, not only the service alone. It is a differentiated phenomenon in the current research, such as the organic influence between the service quality and product. Of course there are such products placed on sale and enjoyed the common service, but at present there is another case that the product is on the market exclusively with the mobile company in here. This article is to estimate service efficiency for Mobile Communication and Cellular company. In this paper, We tried to measure the service quality and overall satisfaction by using Data Envelopment Analysis(DEA), degree of combination and top2box which is a little bit different methodology from traditional ones. This paper uses CCR model in DEA to measure service efficiency in the Mobile Communication.

Consumer needs becomes various in a mature mobile telecommunication market, while service differentiation is hard to achieve. The competition among telecommunication service providers is getting fierce in order to maintain and obtain customers. Moreover, HSDPA caused the intense marketing activity for the move to the next generation customers. Under these circumstances, brand equity can be a key to a long-term competitive edge for mobile phone service providers. In this study, we identified the factors influencing mobile telecommunication brand equity, and its influence on the HSDPA service subscription behavior.

The Korean mobile telecommunication service market is faced with a tremendous competitive period, in which the market is entering into the maturity stage with launching of the 3rd generation service and with introduction of mobile number portability. In general, it is more important to sustain the old customers than to attracting new customers, as the life cycle of an industry is entering the maturity stage in which the growth rate of new customers is decreasing gradually or becoming stagnant. Until now, many researches had tested whether the customer satisfaction and loyalty were the core factors of sustaining customers or not. Also service quality and switching cost were given a remarkable attention for their possibility of exogenous factors, which could exercise effects to customer satisfaction and loyalty. In the same context, mobile telecommunication business has to seek a way to maintain the existing customers instead of promoting new customers. So this study investigates whether the service quality and switching barrier of mobile telecommunication could have effects on the customer satisfaction and loyalty, which are recognized as an efficient means to sustain the current customers. In order to test the hypothesis on the effects of service quality and switching barrier of mobile telecommunication to customer satisfaction and loyalty in Korean telecommunication industry, this study collected the questionnaire response data of students including middle and high school students and undergraduates, who are regarded as the major customers in that mobile telecommunication industry.

Economists have advocated that the privatization and market competitiveness improve the firm's productivity and eventually its service quality. However, the previous researches did not provide the empirical results enough to prove that the privatization and competitiveness do improve the service quality. In this paper, we conducted an empirical research to find whether the privatization and competition induces the quality of service. The mobile telecommunication industry was chosen since it went through bringing the privatization and increasing the competition along with a high attention. We found that the privatization and competition itself does not guarantee the quality of mobile telecommunication service. It is the intensity of competition that improves the mobile telecommunication service quality. The service quality depends mainly on the competitor's competence, i.e. the intensity of competition rather than the competition itself. In sum, when we want to improve the service quality as well as the productivity, we had better increase the intensity of competition by allowing many new strong entries.

The mobile telecommunication service industry plays major role of the realization to the perfect information society in the 21st century and has a great influence in society and culture. The government has enticed the mobile company to keep up to make the mobile service fee low. In this situation, this paper estimates consumer surplus and price elasticity with on-line survey data from the consumer of mobile service. The total estimated consumer surplus of the market is reached to 6.43trillion won. The consumer surplus from SKT is estimated to 4.98trillion won and 1.66trillion won and 0.67trillion won was made by KTF and LGT respectively. The result also shows that consumer surplus is expected to be increased by the increase of the mobile service demand and the sales.

본 연구에서는 국가 간 이동통신서비스의 확산과정에서 국가 간 영향에 의해 한 국가에서의 확산성과가 다른 국가의 확산에 주는 영향을 분석하였다. 그동안 대부분의 이동통신서비스 확산에 대한 국가 간 비교연구들은 주로 국가별로 추정된 확산과정에 대해 사후적인 비교 분석이 일반적인 것에 반하여, 본 연구에서는 최근의 이동통신서비스의 확산이 국경을 넘어 영향을 미치고 있는 현실을 보다 적절히 설명할 수 있다. 본 연구에서는 이를 위하여 다국가 확산모형을 이용하여 한국과 중국, 미국, 일본, 홍콩 등 5개국에서의 이동통신서비스의 확산 과정을 분석하였다. 분석 결과 중국의 이동통신서비스의 확산은 한국, 미국, 일본, 홍콩 등 주변 국가들에서의 이동통신서비스의 확산에 유의한 영향을 받은 것으로 밝혀졌다.

As the wireless mobile telecommunication system has been developed with astonishment, its offering service has also widely been expanded including various data service. Currently, the wireless mobile telecommunication network presents voice service that covers for the most part of the whole service areas. For this reason, the availability of the switching capacity in the mobile switching center(MSC) is manipulated by the required volume of voice service. However, considering the increase of data service, it is desirable for the current switching method to be modified for more efficiency. In this Paper, we analyze the data traffic caused by providing data service in the wireless mobile telecommunication network. For this, we are firstly going to review the result of the analysis in the feature of the data traffic. Secondly, based on the review, we are also going to perform analyzing the other feature of the data traffic normally generated in the wireless mobile telecommunication network. We expect that this paper would be utilized as an elementary source for the feature of the SMS data .traffic and it will be an honour for ourselves to work on it.
