This paper proposes a prepaid system promotion policy for the 3G(WCDMA) MVNO with regard to the newly included paragraphs 3, 4 and 5 of Article 32 (User Protection) and Article 38 (Provision of Wholesale Telecommunications Services) of the Telecommunication Business Act, which was revised on March 22, 2010. As of June 2011, there are only a few prepaid system subscribers to the mobile communications service due to various limitations, including prepay, interconnection, carrier selection, the MVNO policy, and number portability. However, overseas communications service regulatory agencies and service providers are increasingly presenting policies and strategies for mobile prepaid plans, in order to accommodate the various customer demands that are increasing the use of smart phones and data. This paper advances various proposals concerning promotion of the prepaid system by the 3G MVNO under the current Telecommunication Business Act, including separation of the prepaid data system and the mobile network; introduction of a monthly fixed-rate hybrid prepaid system, a top-up system and USIM system; introduction of mobile network carrier selection; differentiated retail discounts between prepaid and post-paid prices; revision of the retail discount policy for wholesale provision; increase in the number of mandatory service providers; and in-depth consideration of the introduction of a number portability policy for the prepaid and post-paid systems.

과거 사무실과 같은 실내 환경에서 무선을 이용하여 네트워크 접속을 위해 개발된 무선랜 기술이 최근 실외 공중망 서비스와 연계되며 미국을 비롯하여 유럽 등지에서 신규 통신서비스 개발이 활발히 사용되고 있다. 이러한 이동환경에 적합한 선불과금 방안은 선불제 요금제도의 필요성이 대두되면서 중요한 연구과제가 되고 있다. 본 논문에서는 무선랜 이동환경에 적합한 선불과금 모델을 제안하고 검증한다. 제안된 과금 모델은 차세대 이동통신의 이동환경에서 적용이 가능한 인터넷 IP 과금 방안을 연구하는데 기반 기술로 이용될 것이다.

이동전화 시장의 팽창으로 인하여 이동전화 사업자간 서비스 경쟁은 치열해지고 있다. 이동전화 사업자들은 시장점유율에서 우위를 유지하기 위해 다양한 요금상품과 요금차별화를 통해 가입자수를 극대화하려 한다. 이동전화 서비스의 요금에는 이부요금제와 선택요금제, 기본료가 없는 선불요금제가 있다. 요금구조는 국가별로 다양한 환경에 따라 차이를 보이고 있다. 영국 규제기관인 Oftel에 의하면, 5개국(프랑스, 독일, 이탈리아, 스웨덴, 영국)을 대상으로 요금수준을 비교한 결과 영국과 프랑스의 이동전화 요금수준은 유사한 평균 수준이였으며 독일과 스웨덴에 비해서는 4-6% 정도 비싸고 이탈리아에 비해서는 27% 정도 저렴한 것으로 나타났다.

국내의 전력 산업은 부정확한 전력수요 예측으로 전력부족과 공급과잉의 주기적 반복이 발생하여 전력 과생산, 에너지 낭비, 전력 과소비와 요금 체납 등의 문제가 발생하고 있다. 이를 해결하기 위해 본 논문에서는 LSTM 알고리즘을 사용하여 전력사용량 예측하고, 정량의 전력을 선구입 할 수 있도록 설계하였다. 제안하는 시스템은 스마트그리드 환경과 인공지능으로 정량의 전기를 구입 할 수 없는 기존의 전력 산업 문제를 보완하여 소비자의 전기요금 절감과 에너지 절약이 가능하다.

Busan city implemented 'taxi transfer discount system' since October 2017 in order to create for new demand taxis. However, due to the low transfer discount amount and limited payment method to prepaid cards, it is difficult to attain the aim. In this study, we investigated the usage status of taxi transfer discount system and the intention to use taxi transfer discount system according to the discount amount level. We established a model of intention to estimate demand of taxi transfer discount using ordinal logistic model. The results of analysis are as following. The critical reason for low usage was to limit taxi transfer discount payment methods to prepaid cards other than post-paid cards which is used for most transportation payment. It was found that the discount rate for taxi transfers was affected in order of payment method, the purpose of the travel, major transportation, frequency taxi use, age, transportation costs, and the discount of taxi transfers. Also, the taxi transfer discount could be expected to increase to 1,550 won based on the price elasticity of demand due to changes in taxi transfer discount rate.

The pre-paid nation-wide interoperable transportation card, which an pay fee of bus, subway, train, and highway with just one card, released in June. 2014. It has started and operated from Seoul, Gyeonggi, and major local metropolitan area. In this paper, after starting of service, we evaluate conformance and interoperability of nation-wide interoperable transportation card system in real situation. Through this, we check the status of its technical operation. For this, we choose 6 region included Seoul, Gyeonggi which are serviced by different transport vendors and check recognition and billing result from field of transportation card terminal. As a result, we can reach that the major nation-wide interoperable transportation card operate normally and deliver CONFIG DF query command. It means nation-wide interoperable transportation card system which use only one card stably adapt the public transport system and it can make user's public transport use convenience higher through the extension of service area.

Recently, the traffic card is gradually utilized and its several supplementary services have been significantly developed. Particularly, since it is possible to pay fees for buses, taxies, subways, parking and tollgates with only one traffic card, new payment method for economically processing has been focused. This paper presents a new receipt management system which allows possibly paying with several digital cards through PC interfacing terminals. The proposed system is mainly composed of three parts: terminals, middleware, and management servers. A terminal part includes processing module for payment/charging and credit/check/debit cards, etc and its operation is fulfilled through a middleware part. A main task of a middleware part is to connect a terminal part to managing servers through middleware applications. Additionally, processing of several receipt items and monitoring of the terminals to product statistical reports based on the processed result are carried out in the middleware. A management sever part is accomplished for collecting all of transaction histories against users and charging items over allowed province and managing statistical information. The proposed system is currently utilized in the Nam-GU district office and the Nam-GU district health center, Busan, S. Korea, respectively for testing its effectiveness. We conclude from this demonstration that the system is more useful and efficient than the previous processing method especially in that variable payment ways are provided and consumption burden is reduced.
