M-commerce services are rapidly emerging with recent advances in mobile devices and wireless communications. Internet Shopping mall managers provide mobile phone users with their mobile shopping malls for m-commerce. However, these mobile shopping malls usually have their own sites which are not compatible with their Internet shopping malls, thus resulting in inefficiency to manage the two kinds of shopping malls. In this paper, we develop a M-commerce content provider system to effectively bring Internet shopping malls to mobile phones by extracting items only concerned to users from product documents. We then apply and evaluate the system over a specific internet shopping mall site. The results show that the system reduces considerably the amount of data transferred to user's mobile phones compared with using general web browsers.

Mobile Internet using mobile devices provides Portability to users and is Spreading throughout out lives. But Practical use of the mobile Internet is insufficient due to it's fundamental limitations. Especially, mobile resources are not sufficient because they are not closely connected under current mobile Internet services which are provided with pre-designed structure. For these reasons it will take a lot more time and effort for mobile Internet to grow as a popular service. In this paper, we are focusing to overcome the local limitation and to enhance the 'Sharing of Mobile Resources' by expanding mutual connectivity between resource objects scattered over the mobile Internet environment. To archive this, we propose the MRSS(Mobile Resources Sharing System). MRSS automatically converts single request from user to multiple instructions based on 'Context-Awareness' to search for proper information. Using MRSS, we can expect 'Mobile Ubiquitous Computing' environment which users can reach to information anywhere, anytime.

Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.

The objective of this research is to identify the factors which influence users' intention to use mobile Internet. There are lots of researches based on Technology Acceptance Model trying to identify the factors which have influence on accepting mobile Internet and its related services. These researches, however, have some limitation in the sense that they focus only on the features of mobile Internet itself while users make overall decision after the comparison of a new service channel with existing service channels in many directions. Therefore, we are going to analyze the impact of users' perception on the difference between mobile and stationary Internet toward their intention to use mobile Internet. We identified the features like ubiquitous availability, context awareness, compatibility, friendliness, and economic value from literature review and developed a structural model about the impact of users' perception on the differences of these features between mobile and stationary Internet toward their intention to use mobile Internet through mediate variables such as perceived ease of use, perceived playfulness, and perceived usefulness. After that, we conducted an experimental analysis for the model, and addressed a solution to rev up the usage of mobile Internet based on the results of the analysis.

This study is to identify quality factors having influence upon mobile internet service performance theoretically, derive the research model and the hypotheses concerning the cause and effect relationship between these factors and service performance and then analyze them empirically. In order to enhance the model's explanation power, trust and cognitive engagement as interviewing variables are included in the model. The theoretical background of this study was brought from relevant literature in the areas of the theory of reasoned action(TRA). technology acceptance model(TAM), product selection model, cognitive absorption theory and etc. The research model and hypotheses were statistically investigated and analysed through convergent and discriminant validity test, reliability test, and path analyses by means of statistical packages SPSS(12.0) and LISREL(8.72). For these empirical analyses. data were collected through the field survey of 373 users who were willing to continuously use the mobile internet services. Based on the results of the analyses, theoretical and practical significance and future study direction were suggested. The results of this study will be helpful to giving a guideline to companies such as mobile telecom, mobile contents provider and mobile handset manufactures when they have to establish the mobile Internet service marketing strategies.

Mobility changes the computing environment of computer users rapidly with the broad use of the Internet. In order to support mobility in the Internet infrastructure, IETF standardized Mobile IP With the use of Mobile IP, the Internet users can use the Internet freely without any change in the IP address configuration when they move from their home networks to foreign networks. In this paper, we implement a test bed for evaluation the performance of Mobile IP to use it in the campus network. By evaluating the effect of the use of Mobile IP on the network performance, we expect that the possible side effect of its direct use in the campus network will be reduced.

Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

As the mobile internet service market is rapidly growing, measuring and managing the service quality become a more critical issue to the service providers. Thus the purpose of this study is to compare SERVQUAL, SERVPERF, and non-difference score measures and to determine which one is superior to measure the service quality of the mobile internet service. This study also aims to analyze the structural relationship between the service quality, customer satisfaction and behavioral intentions (repurchase intention and word-of-mouth). For the purpose, survey data were gathered from the respondents who have used the mobile internet services and an empirical test was conducted. As the first research result, it was revealed that the non-difference score measure showed a much better model than other service measuring models (SERVQUAL, SERVPERF). And the second result was that two service quality factors (tangibles and empathy) among the mobile internet service quality factors significantly influenced the customer satisfaction and also the customer satisfaction had a significant effect on the repurchase and word-of-mouth.
