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.

Location Based Services, or LBS refers to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless internet, the LBS has preconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. This paper describes the open architecture for LBS platform ensuring interoperability among the wireless networks and various location-based application services and the functional requirements for the LBS platform. The LBS platform in a narrow sense provides a standard interfaces for location management and network management for location services as follows, positioning (location acquisition through network or/and handset), location managing, location based functions, profile management, authentication and security, location based billing, information roaming between carriers and the system monitoring independent to specific network or ISP/CPs(Content Providers).

According to broad spread of smart phone, interest for LBS is increasing. but the marine alert system for providing public LBS service. the practical use of LBS is weak because the range of tracking location is from 200M to 1KM in korea. This study try to research the methods for setting up LBS high definition open platform system, good operation of LBS system and improvement of public use of LBS.

The LBS(Location-Based Service), which is based on individual's mobility, is required increasingly as mobile telecommunication and various infrastructures have developed rapidly. The technologies for LBS are location determination technology, service platform technology, contents provider technology and moving object database technology generally. Among these, service platform must be interoperable with location gate-way server and provide common function of billing, authentification, protect location information, privacy control, location trigger and intelligent acquisition and so on. The TTA(Telecommunications Technology Association) published specification that defines a standard protocol for safe and simple interface between LBS client and LBS platform and the OpenLS(Open Location Service) in OGC (Open GIS Consortium) released implementation specifications for providing Location based core services. In this paper, we implemented service platform for LBS which is able to interoperable with location gateway server and contents provider and is caracterized as follows. First, it could require and response location information from different types of location gateway server with same interface. Second, it complies with the standard interfaces with OpenLS 4 contents providers for core LBS. Third, it could provide location of wired phone as well as wireless mobile terminal compling with the standard protocol. Last, it could provide trajectorH information based past location as well as current location, because it is able to interoperable with moving object DBMS. This paper contributes to the construction and practical use of LBS by providing the method of implementation of service platform for LBS.

Moving pattern is as a kind of sequential pattern, which can be extracted from the large volume of location history data. This sort of knowledge is very useful in supporting intelligence to the LBS or GIS. In this paper, we proposed the continuous moving pattern mining approach in LBS platform and LBS Miner. The location updates of moving objects affect the set of the rules maintained. In our approach, we use the validity thresholds that indicate the next time to invoke the incremental pattern mining. The mining system will play a major role in supporting the various LBS solutions.

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.

The types of service using location information are being various and extending its domain as wireless internet technology is developing and its application part is widespread, so it is prospected that LBS (Location-Based Services) will be killer application in wireless internet services. The MODB (Moving Object Database) stores and manages very large current/ past moving object data, so it is very important part in LBS platform. The performance of LBS platform is tightly depending on the performance of this MODB. The other important part is alerting engine in LBS platform, which is system to transmit various value-added information or notify emergency information to mobile phone after triggering specified events. This alert engine is supported as extended function of MODB, that is to say, the alerting function is closely related with MODB. So alert cartridge on MODB must provide not only moving point triggering about going into, going out specified geographical area but also batch alerting about nearest neighbor from specified geographical area. In this paper, we study of extended part on MODB to support the alert engine. And we design alert engine cartridge on MODB before implementing the system.

In this paper, m(mobile)-commerce system based on LBS is implemented. WIPI(Wireless Internet Platform for Interoperability) that supports COD as a mobile VM(Virtual Machine) is used. These experimental results show that the system we proposed could be very efficient for CRM(Customer Relationship Management) and target management. And also, server load and connection time is improved by this system. From now on mobile commerce system based on LBS can be usable at various areas in ubiquitous environment.
