VoIP(Voice over IP)는 패킷교환망을 통해 음성통신을 제공하는 기술이다. 초기의 VoIP에서는 사용상 제약조건과 불편함 때문에 사업모델이 성립하지 못하였다. 무선 광대역통신이 가능해지고, 멀티미디어 서비스에 적합하게 진화함에 따라 VoIP에서 무선접속기술을 이용한 Mobile VoIP서비스를 제공하고 있다. Mobile VoIP의 편리성으로 인하여 VoIP에서 새로운 사업모델이 창출되었고, 웹 2.0과 Mobile 인터넷전화의 결합에 의해 SNS(Social Network Service)으로 서비스가 확장되었다. 이로 인해 많은 서비스 제공자가 발생하였고, 이 서비스 제공 사업자는 크게 이동통신사업자, 소프트웨어 서비스 사업자, 가상이동통신사업자, 그리고 별정 사업자로 분류된다. 4가지의 서비스 제공 사업자는 각각 사업모델이 차별화 되어 있다. 본 논문에서는 Mobile 인터넷전화 기술동향을 살펴보고 서비스 동향을 분석한다. 그리고 Mobile 인터넷전화의 서비스 제공사업자의 차별화된 사업모델을 분석한다.

Mobile GUI design is changing from an existing design that emphasizes intuitive cognitive effects to an affordance design that naturally triggers users' behaviors. However, in the GUI design, the current affordance only uses some partial design elements and cannot achieve effective design, and the concept of affordance design still has confusion and uncertainty. For this reason, this paper redefines affordance by examining the concepts and types of it in the pre-research. In addition, through questioning the type of affordance, a questionnaire was designed for the GUI elements of social software. According to the results of the survey, the evaluation of the affordance of the GUI design elements was derived, and the GUI design of the social software was compared and analyzed. Then according to the deep interviews, a GUI design proposal that can effectively use affordance was proposed.
