WIPI is developed by KWISF(Korea Wireless Internet Standardization Forum) and a wireless internet standard platform adopted by TTA. It needs the certification Process for standard specification in order to confirm interoperability. The WIPI is composed of the HAL, the Runtime Engine, and APIs(WIPI-C, WIPI-Java). nl applications are implemented through WIPI APIs that can be finished by themselves or provided essential functions from runtime engine or HAL. Therefore it needs to certify where the problems occur when errors occurred in a application. In this paper we propose the PCT that certifies a WIPI platform's functionality and APIs and the HCT that certifies HAL APIs. Because the PCT reports the final certification results for the platform it is impossible to know where the problems occur when it fails to certify platform. So, it needs to certify the HAL regardless of platform certification.

We developed the CNU nt emulator which is an development environment for WIPI applications, wireless Internet applications for cellular phones with the WIPI software platform. The CNU WIPI emulator provides stable memory management and ability of installing, executing, deleting or managing WIPI applications. WIPI WAM provides quick execution of applications and convenient debugging function. In this paper, we describe the design, implementation issues of the CNU WIPI emulator and show its correctness of executing and performance improvement over $25\%$ by comparing it with other WIPI emulators.

Mobile Internet has different platform cause interrupt activation of mobile internet because contents providers have each different development environment. To use of WIPI(Wireless Internet Platform for Interoperability) developer by KWISF(Korea Wireless Internet Standard Forum) founded to solve this problem guarantee independence of hardware and interpretation of mobile application. In this paper, we research method to activate WIPI which is standard platform to develop applications easily and efficiently in mobile environment and we implement WIPI application to show the excellent of WIPI in mobile development environment.

As the wireless internet applications are spreading more fast and the mobile devices are being used increasingly, it has recently been activated to develop a variety of contents for mobile service. Mobile services can be enjoyable whenever and wherever on would like to. They became so universal that they might reach all the area where the wire has never approached before. This study is to suggest a mobile game system based on the technology called WIPI(Wireless Internet Platform for Interoperability), which can be easily available to anyone who would like to enjoy it. Game contents to use WIPI can allow the mobile carriers to provide users to download the common mobile application throughout the wireless web by sharing the internet platform. This can eventually lead to the generalization of transforming west game contents into WIPI-based. Therefore, the market of WIPI-based game contents will be expected to grow at high speed and its significance deserves to be considered for commercialization.

For avoiding the waste of costs for building each mobile platform according to each mobile communication vender, KWISF proposed WIPI platform standard. Already the venders are providing mobile map services which are adapted on their own platforms. Because the integration of various mobile platform was performed to WIPI standard, the changes of platform and component API may cause the environment changes of mobile nap services. This study shows the design and implementation results of mobile map services adapted to WPI environments.

모바일 표준 플랫폼 WIPI(Wireless Internet Platform for interoperability)는 모바일 단말기에 탑재되어 응용프로그램을 실행할 수 있는 실행환경을 제공하는 국내 모바일 표준 플랫폼이다. 2002년부터 개발이 시작되어 현재 WIPI 2.0 규격을 탑재한 모바일 단말기가 출시된 상황이다. WIPI 2.0 규격은 PC연결 등의 표준 입출력, 폰카메라, 위치알림 기능, 보안통신 등의 서비스까지 규격화하고 있으며, 차기 버전에서는 휴대폰은 물론 휴대인터넷이나 위성 디지털멀티미디어방송(DMB) 단말기 플랫폼으로의 확장도 모색되는 등 발전가능성이 크다. 그러나 WIPI가 고려되지 않고 설계된 현재의 운영체제상에서 구현된 표준 플랫폼은 설계상 제한이 있으며, 미들웨어의 성격이 강하기 때문에 특정하드웨어와 운영체제에서의 WIPI 지원여부에 따라 응용 분야에 제약이 가해진다. 본 논문에서는 모바일 디바이스를 위한 연구개발을 목적으로 개발된 오픈소스기반 운영체제인 OpenOS의 커널수준에서 WIPI 표준 플랫폼의 HAL(Handset Adaptation Layer)과 WIPI-C 필수 API를 구현하여 성능의 개선과 표준 플랫폼을 위한 운영체제로의 발전 및 활용 가능성을 제시한다.

The present study analyzes the social equilibrium of wireless internet platform market before and after the adoption of WIPI(Wireless Internet Platform for Interoperability). When market prevails operator ownership, as opposed to manufacturer ownership, with heterogenous platforms becomes a more likely and desirable solution. After the adoption of WIPI, social equilibrium is achieved only if operators perceive that the cost reduction and the interoperability effects from investing in WIPI fully offset the appropriation effect from investing in heterogenous platforms.

In this paper, we propose a specification-based intrusion detection system for WIPI(Wireless Internet Platform for Interoperability). In proposing the system, we focused on providing lightweight code, supporting multiple languages and hardware independence. The proposed system is based on an algorithm which detects an intrusion to main API of WIPI-HAL(Handset Adaptation Layer) and defines the prototype of mIDS(mobile IDS) API group that it can be added on the HAL. Moreover, we prove apply possibility through a WIPI emulator using java library.

At present, Authoring tools, which are used to develop the WIPI applications are less convenient to be coded. Usually, the programming tools only focus on the grammar while scarcity of visualization. Developer forced directly codes all times during the development by this cause. As a procedure for rapid WIPI Application Development, in this paper, WIPI API High Level Component is first visualized, in order words, graphic control is developed. Second this control is used in designing the mobile layout. Then UI Markup Language and source code can be generated automatically. With this view, we propose the JIML(Jlet Interface Markup Language) with UI Markup Language based XML of WIPI Jlet Platform and also present the transformable rule for generation to the WIPI code about WIPI Jlet UI from offered JIML. Also we implement the WIPI Jlet Generation System to make the generation to JIML, WIPI code. The Implemented System provides efficiency when developing WIPI Business Application, and helps to enable rapid development.
