요즘 작고 빠른 장치에 관한 새로운 열풍이 불고 있다. 이들은 이동 중에도 정보에 접근할 수 있고, 웹과 이동 전화기의 개념을 합쳐 놓은 장치라고 할 수 있다. 무선 애플리케이션 프로토콜 (Wireless Application Protocol : WAP)은 산업 전반적인 표준으로서 인터넷 컨텐츠와 서비스를 이동 전화기에서 접속할 수 있도록 해주는 통신 프로토콜과 애플리케이션 환경을 정의한다. 본 논문에서는 오픈소스로 진행되고 있는 Kannel WaP Gateway를 이용하는 WAP브라우저를 설계및 구현하였다. 임베디드 리눅스가 탑재된 모든 단말기에서 동작할 수 있으며 무선 인터넷을 통해 WAP사이트에 접속하고 컨텐츠를 디스플레이 할 수 있도록 해준다.

According to development and diffusion of mobile communication device, the needs to use internet service with mobile communication device has increasing. so, new services has required for mobile communication device to use internet. therefore, internet accessing technologies are researched f9r many mobile communication device and the connection that utilize U and WAP, between mobile communication device and internet is being researched. But, small display of mobile communication device has weak point to use internet. so, in this paper, we design the voice supported WML Browser to overcome the weak point.

In this research, the concept and application structure of WAP were investigated and the mathematics content of elementary schools was applied to WAP directly for its implementation. WML and WMLScript programs were made by using the editor. The, the image file that was suitable for WAP program was made by using the image converter. We directly implemented the program using WML and WML Script through the emulator of Neple and that of Phone.com. The implementation result of Neple's emulator confirmed the possibility that the educational program with a simple image and a calculation function can be implemented through WAP Phone.com's emulator did not represent the result shown by Neple's emulator. This was due to the different browser functions of the wire service companies and different input content of the headers of the WML. It showed that the implementation results of image files and programs were differently represented depending on the kinds of WAP browsers.

Due to the recent surge of wireless Internet and concurrent development of the end user terminal devices having standardized graphical user interface(GUI) and unified operation mechanism for better interactivity in information representation and ease of use, various efforts on the improvement of GUI is widely recognized as one of the key factors that will usher in the next stages of the wireless Internet for the users. Especially, improved usability along with unique visual effect are considered to be the key elements for GUI considering the rapid improvement of the resolution and color on the end user handset devices; thus, the study and research on the subject of GUI is expected to increase along with the wireless Internet using smart phones. User interface of the wires Internet end user handsets will have a definite and significant effect on the user interaction as well as productivity. Domestically, wireless Internet service providers and GUI design companies are making various efforts in producing a common GUI models for standardized operation scheme and improved graphical display capabilities of the hand phones, PDAs and smart phones. In the study, Nokia 3650 model and Microsoft Orange SPV model were chosen as test devices for usability comparison and data collection to collect directional benchmark data in developing next generation smart phone user interface integrating PDAs and phones. The mail purpose of this study is to achieve the most efficient user accessibility to WAP menu through intensive focus on developing WIPI WAP menu having most effective usability for the users in their twenties and thirties. The result of this study can also be used as the base research materials for WAP service development, VM browser development and PDA browser development. The result of this study along with the evaluation model is expected to provide effective analysis materials on the subject of user interface to the developers of the wireless Internet user devices, GUI designers and service planners while short listing key factors to consider in developing smart phones therefore serving as the GUI guideline of WIPI phones.

We suggest AKL(abstract kernel layer) to. the design and implementation of WAP on basis of multi-platform. AKL is running on the various kernel including REX, MS-DOS, MS-Windows, UNIX and LINUX. For the purpose of it, AKL makes machine-dependant features be minimized and supports a consistent interface on API(application program interface) point of views. Therefore, It makes porting times of a device be shorten and makes easy of maintenance. We validated our suggestion as a consequent of porting WAP into PalmV PDA and mobile phone with AKL.

모바일 표준 플랫폼 WIPI(Wireless Internet Platform for Interoperability)는 하드웨어 독립적으로 설계되어 어떠한 무선단말기에도 사용가능하며 개발언어인 C와 자바를 선택적으로 사용할 수 있는 국내 무선인터넷 표준 플랫폼이고 WAP2.0(Wireless Application Protocol) 규격은 XHTML의 사용으로 유.무선 인터넷의 통합 컨텐츠 제공이 가능한 무선 응용프로토룰이다. 본 논문에서는 WIPI 표준 플랫폼에서 단말기의 무선인터넷 활용을 위해 XHTML을 마크업 언어로 채용한 WAP2.0 규격의 마이크로 브라우저 원형(Prototype)을 설계하여 구현하였고 WIPI 시뮬레이터를 사용하여 응용프로그램으로 구현된 마이크로 브라우저의 동작실험을 함으로써 WIPI 표준 플랫폼을 위한 WAP2.0마이크로 브라우저의 활용 가능성을 제시한다.

현재 세계적인 이동통신 업체들은 대부분 XHTML Basic 을 수용하여 새로운 브라우저들은 WAP 프로토콜을 배제하고 TCP/IP 기반의 통신을 지원하는 경향을 나타내고 있다. 본 논문에서는 이러한 기술 추세를 반영하여 WAP 2.0 을 지원하는 PalmOS 용 XHTML 브라우저를 개발하였다. 본 브라우저의 특성은 이식성을 높이면서 휴대용 단말기의 자원 제약을 극복하기 위하여 이미지 변환 프락시를 활용하는 방식을 채택한 점이다.

In case of implementing a complicated application like WAP (Wireless Application Protocol) in a mobile terminal with the characteristics of bare machine and versatile kernel aspects of which are control, interrupt and IPC(Inter Process Communication), a special methodology should be needed. If not, it will cause more cost and human resources, even delayed product into launching for the time-to-market. This paper suggests AKL, (Abstract Kernel Layer) for the design and implementation of WAP on basis of multi-platform. AKL is running on the various kernel including REX, MS-DOS, MS-Window, UNIX and LINUX. For the purpose of it, AKL makes machine-dependant features be minimized and supports a consistent interface on API (Application Program Interface) point of view. Therefore, it makes poring times of a device be shorten and makes easy of maintenance. We validated our suggestion as a consequent of porting WAP into PlamV PDA and mobile phone with AKL.

This paper describes technical method about remote control and monitoring of local system by use personal mobile device in anytime and anywhere. Therefore, the user don't need to stay in operation room of local system. The PC server environment for the mobile connection are constructed with Apache web server, PHP and MySQL ODBC. The mobile internet homepage for the remote mobile connection is designed by Anybuilder software and mobile simulator, Openwave SDK 6.2 is used for the development. The mobile internet program can be applicate to all of domestic communication companies LGT, SKT and KTF. We use KTF mobile contains WAP browser for the test. We used NI Labview software to control and monitoring of local system. The local system, which will be controlled remotely have constructed with analog/digital signal acquisition device, signal control board and their software. By experiments, we confirmed remote control by mobile device are possible.

WAP(Wireless Application Protocol)을 기반으로 한 무선 인터넷 분야의 발전과 더불어 엄청나게 늘어난 무선 인터넷 이용자들의 컨텐츠에 대한 요구가 다양해지고 있다. 따라서 CP(Content Provider)들은 무선 장비에 맞게 설계된 WML(Wireless Markup Language)과 WMLScipt를 무선 장비를 사용하지 않고, 실제와 비슷한 상황에서 컨텐츠(Content)를 개발할 수 있는 환경이 필요하게 되었다. 본 논문에서는 무선 웹 컨텐츠를 좀 더 쉽게 개발할 수 있도록 도와주는 WML 마이크로 브라우저의 구현에 대해 기술한다. WML 마이크로 브라우저는 WML 파싱(parsing) 모듈과 브라우징(Browsing)모들로 구성되고. 클라이언트 측 WAP 스택으로 요청한 결과로 얻은 컨텐츠를 화면에 출력한다.
