As the spread of LBS(Location Based Service), MDT(Mobile Data Terminal) and PDA (Personal Digital Assistant) services using mobile terminals, various systems are under development to to manage the performance of these services. This paper describes a mobile performance management system which is implemented to test the performance of mobility between the user and the terminal or between the terminal and the mobile server automatically in the mobile-user field. The system has four modules: scenario management module, MDT monitoring, LBS monitoring, and PDA monitoring. The scenario management module manages the performance by monitoring all modules. The LBS monitoring module monitors LBS call attempt stage, call connecting stage, and LBS test for established connection. Thus, the LBS monitoring module manages the performance for every stage of the call. The MDT monitoring module monitors the performance according to the input command and the PDA monitoring module monitors according to the input from the set up and the execution menu.

The location based service means the service using the location information and the service used based on the location information comes into the spotlight as the critical information of the future mode townsman ubiquitous-City construction. LBS settles down as the core element of ITS or the telematics as the cutting edge technology appearing according to the power generation of the mobile communication technology and recently gradually broadens a range to the public safety service including the distribution management, the asset management, a children and old and the weak protection means, the disaster preparation rescue service like the E-911 of U.S. In the national, the technical regulations about the ground wave LBS was established at November 2005 for the first time in the country. but it actually operated and problems were deduced. Therefore, in this paper, domestic and foreign LBS usage trend and technical standards case try to be analyzed for the revision of the technical regulations of the ground wave LBS serviced in the national and the national technical standards bill for the revision tries to be prepared based on this.

Rendering maps is an essential feature of the user interface component of a location based service (LBS) system. However, a developer may not too much worry about implementing the rendering maps part of his or her system because there are quite a few publicly available libraries that provide all kinds of functions of manipulating maps. Google Maps, Yahoo Map, Naver Map, Daum Map, and so on are example sites that provide those libraries. Rendering drawings is to indoor LBS as rendering maps is to LBS. However, there is no such thing as Google Maps that provides libraries for rendering drawings. This paper introduces a few web services and a library that is useful in developing user interfaces of indoor LBS systems.

This paper describes the LBS Terminal Standard Platform based on WIPI. The LBS Terminal Standard Platform based on WIPI is API for obtaining the location information in the mobile standard platform providing the environment which is mounted on the mobile communications terminal and can platform an application. The mobile Platform consists of HAL API, C API and Java API that it is able to process Location Information data among wireless network. It is defined and developed at the HAL sections and C sections based on Generic I/O, and It describes in details in this paper. This standard Platform is expected to be utilized as the base specification in developing the LBS Terminal development technology and standard method to LBS application developers.

유비퀴토스 환경에서 차세대 LBS(Location-Based Service) 서비스를 위한 콘텐츠를 제공하기 위해 각 단말기와 환경 및 사용자의 취향에 맞게 콘텐츠를 리퍼포징(Repurposing)해야 한다. 콘텐츠 리퍼포징이란 유비퀴토스 환경 구축에 필수적인 핵심 기술로서, 하나의 원본 콘텐츠를 사용자의 선호도, 단말기 특성, 네트워크 특성 등에 따라 최적의 상태로 적응/변환하여 제공함을 말한다. 본 논문에서는 다양한 사용자에게 차세대 LBS 서비스를 위해 콘텐츠의 사용자 정보와 콘텐츠 관련 환경 정보 등을 분석, 전달하기 위한 방법론을 제안하고, 또한 리퍼포징된 콘텐츠의 다양한 정보 분석 방법을 제공하기 위한 미들웨어 아키텍처를 설계한다. 이는 학문적으로 새로운 최첨단의 이론과 기술을 창출하고 이를 기반으로 차세대 LBS 서비스 분야에 혁신적인 역할을 할 것으로 기대된다.

According to proliferation of smartphones and extension of various services utilizing location information, markets of Location Based Service(LBS) have been activating all over the world. However, as the privacy violations of personal location information have been continuously increased, interests in the deregulation have been grown as well. While the regulations of location information can protect personal information and privacy, it causes some negative affect in terms of development of diverse services and industry activation. In particular, Korea is the only country that has applied strict restrictions of LBS by making location information related independent 'Location Information Protection Act'. As a result of this, the issues that LBS industry has no longer developed in Korea and it is necessary for us to relax the regulations have been consistently raised. Thus, this study confirmed that there was the negative(-) relationship between the regulations and the market activation of LBS by comparing and analyzing the correlation between the market growth rate of LBS and relevant regulations at home and abroad; the regulations are strengthened, restrictions in market entry and the business performance can occur. In other words, LBS business will be able to be activated if the regulations which have not directly related to the privacy have been relaxed.

LBS(Location-Based Service) is one of the smartphone application services which has been receiving great attention recently. Various applications of smartphone use LBS to provide innovative services. However, use of LBS raises privacy concerns because the location information of users is constantly exposed. Privacy calculus perspective attempts to understand the characteristics of the user's privacy. It is based on the risk-benefit analysis in the economics' perspective. That is, when the benefit expected through personal information disclosure is higher than risk, we are willing to provide personal information. This research suggested a research model based on the privacy calculus perspective to clarify the effect of information disclosure intention of smartphone LBS application users. Based on the main factors of privacy calculus, perception of privacy risk and privacy benefit, the relationship of the perceived value and the information disclosure intention was empirically analyzed by utilizing structural equation modeling(SEM) methodology. According to the results of the empirical analysis, it was found that all relations have statistically significant explanatory power except the relation between privacy concern and information disclosure intention. This study showed a strong evidence of antecedent factors based on privacy calculus of personal information disclosure in smartphone LBS applications.

There are wireless location acquisition technique, LBS platform technique, and LBS application technique in the important technical elements of the LBS. In this paper, we design a location data management system which is the core base technique of the important technical elements of the LBS. The proposed system consist of an application interface of LBS, a query processor of application. service, a location estimator of the moving objects, a location information manager, a real-time data receiver, and a database of location data. This system manages efficiently the location change information of the moving objects using the database technique, suggests some useful inform to the users of LBS, and supports operation and facility of location estimation to process continuous location data of the moving objects. On the basis of location data triggering, this system supplements the problem of the related location data management systems to complement the loss of location data in the environment of real-time.

This service uses beacon with BLE technology, and USER APP has priority with Anchor IPS which secures location and device. Since then, it has been linked with character beacons that can be used in various places. The character beacon which is recognized as a service is able to confirm the user's location through API key of the LBS CMS server, and receives various contents services of the UESR CMS server. The service network consists of character beacon, Anchor IPS, USER APP, LBS CMS server, and USER CMS server. The purpose of the service is to promote local tourism and local culture to tourists through local unique characters.
