Recently, the technologies related with location-based services have been a promising and vigorously researched area in mobile telecommunication industry. LBS have obtained increasingly high attention particularly in domestic area, due to increases in various LBS services supplied by mobile telecommunication companies. LBS technologies are classified by sub-technology such as location determination technology, LBS platform technology, and LBS application services technology. In this paper, I have examined the trend of LBS technologies by analyzing the issued or published patents from 1991 to 2005. The analyzed results are very useful for avoiding overlapping efforts in developing the LBS related technologies, and searching the direction of development of technologies which are different from previous ones.

무선 인터넷 기술의 발달과 응용의 확산으로 인하여 위치 정보를 이용한 서비스 형태는 아주 다양하여 지고 있으며, LBS(Location-Based Services)라는 형태로 국내외 시장에서 급속히 확장하고 있다. LBS 플랫폼은 이러한 위치 기반 서비스를 가능하게 하는 핵심 요소이며, 위치 정보 제공 게이트웨이, 위치 응용 서버, 핵심 기능 제공 서버 등과의 상호 운용을 지원해야 하며, 개인 및 서비스에 대한 프로파일 관리, 과금 처리, 이동체 트리거 등의 기능을 제공하는 시스템이다. 즉, 모든 위치기반 서비스를 수행하려고 하는 개인 혹은 응용 서비스 제공자들은 이러한 LBS 플랫폼을 거쳐, 위치 및 다양한 핵심 기능의 조합 형태인 서비스를 제공 받게 된다. 표준화된 소프트웨어 기술인 웹서비스는 LBS 플랫폼과 타 시스템(솔루션, 핵심 기능 제공 서버, 위치 정보 제공 서버 등)과의 인터페이싱을 가능하게 하는 표준 인프라이다. LBS 플랫폼 웽 서비스는, 솔루션 서버에서 요청하는 서비스에 대한 과금 처리를 위한 자체 과금 비즈니스 모델을 포함하고 있으며, 이러한 과금에 대한 처리를 수행하면서 타 시스템과의 상호 운용은 여러 가지 형태로의 구성이 가능하다. 이에 본 논문에서는 LBS 플랫폼이 상호 운용하는 주요 시스템과의 인터페이싱을 위한 웹 서비스 구성 방법에 대한 방안을 제시하고자 한다.

As Internet usage is becoming more common worldwide and smartphone become necessity in daily life, technologies and applications related to mobile Internet are developing rapidly. The results of the Internet usage patterns of consumers around the world imply that there are many potential new business opportunities for mobile Internet technologies and applications. The location-based service (LBS) is a service based on the location information of the mobile device. LBS has recently gotten much attention among many mobile applications and various LBSs are rapidly developing in numerous categories. However, even with the development of LBS related technologies and services, there is still a lack of empirical research on the intention to use LBS. The application of previous researches is limited because they focused on the effect of one particular factor and had not shown the direct relationship on the intention to use LBS. Therefore, this study presents a research model of factors that affect the intention to use and actual use of LBS whose market is expected to grow rapidly, and tested it by conducting a questionnaire survey of 330 users. The results of data analysis showed that service customization, service quality, and personal innovativeness have a positive effect on the intention to use LBS and the intention to use LBS has a positive effect on the actual use of LBS. These results implies that LBS providers can enhance the user's intention to use LBS by offering service customization through the provision of various LBSs based on users' needs, improving information service qualities such as accuracy, timeliness, sensitivity, and reliability, and encouraging personal innovativeness. However, privacy concerns in the context of LBS are not significantly affected by service customization and personal innovativeness and privacy concerns do not significantly affect the intention to use LBS. In fact, the information related to users' location collected by LBS is less sensitive when compared with the information that is used to perform financial transactions. Therefore, such outcomes on privacy concern are revealed. In addition, the advantages of using LBS are more important than the sensitivity of privacy protection to the users who use LBS than to the users who use information systems such as electronic commerce that involves financial transactions. Therefore, LBS are recommended to be treated differently from other information systems. This study is significant in the theoretical point of contribution that it proposed factors affecting the intention to use LBS in a multi-faceted perspective, proved the proposed research model empirically, brought new insights on LBS, and broadens understanding of the intention to use and actual use of LBS. Also, the empirical results of the customization of LBS affecting the user's intention to use the LBS suggest that the provision of customized LBS services based on the usage data analysis through utilizing technologies such as artificial intelligence can enhance the user's intention to use. In a practical point of view, the results of this study are expected to help LBS providers to develop a competitive strategy for responding to LBS users effectively and lead to the LBS market grows. We expect that there will be differences in using LBSs depending on some factors such as types of LBS, whether it is free of charge or not, privacy policies related to LBS, the levels of reliability related application and technology, the frequency of use, etc. Therefore, if we can make comparative studies with those factors, it will contribute to the development of the research areas of LBS. We hope this study can inspire many researchers and initiate many great researches in LBS fields.

Location Based Service (LBS) is a service provided to the subscribers based on their (or others') geographical location. Interest in LBS has increased not only in the aspect of promoting utilization, including the public usage such as emergency rescue, but also in the aspect of protecting the personal location information of the subscribers. This study aims to suggest and classify the business models for LBS services, focusing on the flow of the personal location information. Each business model is reviewed from the perspective of protecting the location privacy of the subscribers.

Due to the advancement of mobile wireless networks, various LBS's (Location Based Service) with the knowledge of mobile station's current position are emerging. Providing LBS is very essential feature in Mobile WiMAX networks such as WiBro networks for their competitiveness. To this end, WiMAX Forum has established recently the network architecture and protocols for providing LBS and they are included in the Network working group's release 1.5 documents. Though there have been many research efforts on location determination in Wibro networks, none of them addresses the location determination mechanism complying to Forum's recent LBS standards. This paper proposes an enhanced TDOA-RTD combined location determination mechanism, which complies to the Forum's LBS architecture.
