Since 1999, mobile internet service has been increasing rapidly. According to the Ministry of Information and Communication (MIC) of the Republic of Korea, the size of mobile service market is forecasted to be valued at approximately 10.5 trillion won in 2007. For this reason, many mobile service providers have adopted customer-centered strategy for the successful business in the mobile internet services. Thus, this research examines the rations of service quality, user satisfaction, and additional use intentions with 88 users (male and female) of mobile internet service using structural equation model (SEM). The result shows that there is a difference between male and female using mobile internet service regarding the quality factors of mobile internet service. This study provides some guidelines for the successful strategic planning of customer-centered mobile internet services in gender.

Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.

Recently, the internet and mobile telecommunication is proliferating rapidly in the whole world. In accordance with this, people have growing desire to use the internet without the limitation of the space; as a result, the mobile internet users are incredibly increased. However, the established study about the mobile internet emphasize the technical aspects. Therefore, this studies finds the significant factors that affect the use of mobile internet service. This study suggests the enterprises getting the service direction which they will use as a strategy in the future. In order to do this, the study examines the factors which can affect the using of the mobile internet service and analyzes the established study about the quality of the information system and the internet service. The result of the survey shows that the factors affecting the use of the mobile internet service are the stability of the system, the convenience of the system, and the response of the service. It also appears that the satisfaction of the mobile internet service affects the attention of the users to using the mobile internet service. The five theories are selected from the ten creative theories, these explain that it is a little unreasonable to design the model which is related to the prior study of the information systems. It will be more deeply scrutinized to analyze the effect of the satisfaction and the utilization of the users through the quality of the information contents.

전국망 규모의 망 설계 및 QoS가 적용된 Mobile-WiMAX 시스템과 54Mbps의 광대역 서비 스가 가능한 WLAN 시스템으로 구성된 계층적 네트워크는 VoIP, VOD, 화상전화 등과 같은 실시간 서비스를 포함한 다양한 무선 인터넷 서비스를 제공한다. 그러나 실시간 서비스를 이용하는 사용자가 Mobile-WiMAX/WLAN 계층적 네트워크에서 핸드오프를 수행할 경우, 특히 Mobile-WiMAX 네트워크에서 WLAN 핫스팟 지역으로 핸드오프를 할 경우 핸드오프 지연으로 인해 사용 중인 서비스가 끊기게 된다. 본 연구는 Mobile-WiMAX(IEEE 802.16e) 규격에서 제시된 서비스 종류(ToS) 파라미터를 이용하여 vertical 핸드오프 수행 기준이 되는 vertical 핸드오프 프로세스를 제안한다. 이 프로세스를 이용하면 실시간 서비스를 사용 중인 사용자는 핸드오프 수행을 일정시간 지연하므로 실시간 서비스의 끊기는 불편함을 해소할 수 있다. 본 논문에서 제안한 프로세스를 이용할 경우 Mobile-WiMAX/WLAN 계층적 네트워크에서 vertical 핸드오프 수행 중의 실시간 서비스 이용에 제한이 없어진다. 이는 사용자 편의 중심의 서비스를 실현할 수 있게 될 것이다.

Service and technology for the future hyper-connected society, which is every information receive through the mobile internet, will be an Internet of Things. Thus, it is mandatory to derive key standardization work item and establish strategy for the global business with the standardization of device and service platform by the application service. In this study, by analyzing the domestic and international market trends, state of technical development, and standardization of technology, we identified the open platform is the stepping stone for achieving the goal which is establishing the virtuous circulation of IoT ecosystem. Also, we defined emphasized key standardization work item for achieving the open platform are network, server, access authentication, billing system, and software platform. After that, we proposed future strategy direction of standardization. This research could be contribute to the IoT service diffusion by realizing IP communication among low power wireless terminals and implementing light-weight standard internet protocol.

The widespread use of smartphones with a variety of features has enabled mobile Internet-based services. One of these is online-to-offline (O2O) based services that connects online users with offline stores to add value. Applying this O2O strategy to local information retrieval induces online users to be linked to offline regions, thereby enabling the exchange of local-based information and helps create new value. This paper proposes and illustrates the implementation of O2O-based a local information providing service that utilizes photos of the local attraction. Also, we propose a fake-free ranking method to provide reliable local information to users and suggest its application of the service.

The dynamic network state and the mobility of the terminals make the service function chain (SFC) orchestration mechanisms based on static and deterministic assumptions hard to be applied in SDN/NFV mobile edge computing networks. Designing dynamic and online SFC orchestration mechanism can greatly improve the execution efficiency of compute-intensive and resource-hungry applications in mobile edge computing networks. In order to increase the overall profit of service provider and reduce the resource cost, the system running time is divided into a sequence of time slots and a dynamic orchestration scheme based on an improved column generation algorithm is proposed in each slot. Firstly, the SFC dynamic orchestration problem is formulated as an integer linear programming (ILP) model based on layered graph. Then, in order to reduce the computation costs, a column generation model is used to simplify the ILP model. Finally, a two-stage heuristic algorithm based on greedy strategy is proposed. Four metrics are defined and the performance of the proposed algorithm is evaluated based on simulation. The results show that our proposal significantly provides more than 30% reduction of run time and about 12% improvement in service deployment success ratio compared to the Viterbi algorithm based mechanism.
