In the recent a mobile internet makes a change in internet business. The mobile internet service is resulting in M-commerce. Even if M-commerce provides only information service, there will be much possibilities to make applications in various areas such as, delivery service, trading service, banking service etc. in the near future. Delivery service requires many steps in processing, originally. This study is designed to implement a mobile system which makes short in delivery process. It includes that a delivery man receives a signature on a paper and input data at the delivered place by using PDA at hand. The mobile system will be contributed to shorten delivery speed. It is proposed to implement the mobile office system for improving service efficiency in the business of delivery service.

Recently the wireless-internet has been spreading extensively. People are spending a large part of their time gaining access to information using a mobile device. With the rapid growth of on-line Electronic Commerce, the use of mobile devices creates a new paradigm that provides users with location-independent real time service. Although this new paradigm does have some advantages, limited process speed, low bandwidth, the low battery capacity of mobile devices, and a high rate of wireless network errors causes many overhead expenses during service time with the server. In this paper, we suggest an autonomous service delivery system, which provides mobile agent capability to users that cannot maintain a connection. We have developed the system based on java mobile agent technology. Using this system, we can provide more effective service to users when the user is sending requirements for service through a mobile device that has limited resources. Furthermore we can manage the contact server dynamically when new services are added.

It is expected that the next generation mobile communication system will be a service-driven developed system capable to realize the human-centric mobile convergence services. and it is different from the technology-driven development approach of the second and the third generation mobile communication systems. As a preliminary research work on such service-driven system development approach for the next generation mobile communication system. we developed the scenario based service analysis process (2SAP) framework to derive core service technologies and functionalities. In this paper. we propose the next generation mobile convergence service business model creation methodology based on research results of the 2SAP framework. To achieve this goal, we first establish a service model contains several components such as infrastructures. operations. and provision of services that are indispensible for providing next generation mobile services. Then, the next generation mobile services and its corresponding business models can be created by adding service and value flows to the developed service model after defining necessary components of business model including actors, their relationships, and roles.

Mobile service is highly becoming in the limelight on information society by offering infringement problem about individual privacy or information by political and scientific interest This study is focusing on primary LBS application Mobile service that emphasize position confirmation, especially, looking for friends. The aim at this study grasps user productivity factor of LBS application Mobile service, and analyses whether some have relations with value and action determination of LBS application Mobile service. According to result, Mobile service applying position service is supported with usefulness and system quality, adaptedness. On the other hand, Usability and social effect, privacy weren't embossed by leading person. Mobile service applying position service is changed with a person who have experience looking for friend. This study has systematically analysed about LBS application service by leading person

Recently MVNO has been adopted to reform the monopoly structure of mobile telecommunication industry in Korea. MVNO is expected to not only enable mobile telecommunication industry more free, but also provide various welfare service with customers, in particular mobile payment system service. Based on TAM, this paper is to investigate the affecting factors of intention to use of mobile payment system service in MVNO environment. The results indicate that all system quality factors are significantly related to both perceived usefulness and perceived easy of use, but only stability of service quality factor is significantly related to the perceived usefulness. Perceived easy of use was found to be siginificantly related to the intention to use of mobile payment system in MVNO environment, but percevied usefulness was not.

Interference scenarios and methodologies between a terrestrial mobile service (MS) system and mobile-satellite service (MSS) system in a co-channel environment are established. Taking into account a practical deployment situation for both systems, we perform computational simulation of interference in terms of carrier-to-interference ratio (C/I) and interference-to-noise ratio (I/N) to evaluate the cofrequency interference from an MS system into an MSS system, and from an MSS system into an MS system, respectively. The methodology and results can be used as a guide when planning the deployment of MSS and MS systems with no unacceptable interference impact between them.
