This change of trend influences greatly on business methods accordingly. Therefore many enterprises are trying hard to adopt mobile business in order to gain competitive edge of their products and they are in need of more effective and stable mobile solutions. However, the method of establishing optimal mobile computing environment and how to handle existing business process and use vast amount of database are still needed. Therefore this paper tries to realize a mobile middleware system as a mobile business establishment supporting tool that could link various computational resource on wired internet with wireless LAN, mobile phone network, and mobile devices. To accomplish that specific goal, this paper provides a powerful tool of mobile and wireless application data access that could expand the line of business already set up in general enterprises easily and rapidly into mobile environment. When this suggested solution is applied in the field of industry, it can economically change legacy business process into mobile environment without having to change existing logic and resources at all. 논문 14-39B-02-06 한국통신학회논문지(J-KICS) '14-02 Vol.39B No.02 http://dx.doi.org/10.7840/kics.2014.39B.2.102 102 First Author : 동원대학교 스마트IT콘텐츠과, ijlee@tw.ac.kr, 정회원 논문번호:KICS2013-11-485, 접수일자:2013년 11월 6일, 심사일자 : 2013년 12월 16일, 최종논문접수일자 : 2014년 2월 10일 논문 / 모바일 비즈니스를 위한 모바일 미들웨어 시스템 설계 및 구현
