This short paper is aimed to discuss the challenges for location-based services and proposes our framework, which makes it possible to obtain information from heterogeneous sources, and further set up the collaboration between Data Repositories and derived Top Hits Repository to improve the request-response efficiency. In our framework, the Data Handler, Profile Manager, Data Repository and TOP...

Location awareness is one of the fundamental problems in tomorrow’s wireless networks. With the advent of GPS, LBS have found applications in many different fields. Most of the LBS applications offered by wireless carriers as of today are mainly relied on the GPS technology. In areas where there is a clear LOS to GPS satellites, this technique provides a good estimate of the user’s location on ...

Location-based applications and services will get increasingly important for mobile users of the future. They take into account a mobile user's current location and provide a location-dependent output. Often, location-based applications have to deal with raw location data of specific positioning systems (e.g. GPS) and perform further processing to get an appropriate representation. In this pape...

One of the most obvious technologies behind Location Based Services (LBS) is positioning, with the most widely recognized system being the Global Positioning System (GPS). There are, however, other means of positioning in addition to GPS. These other technologies are network based positioning and typically rely on various means of triangulation of the signal from cell sites serving a mobile pho...

As the new communications era aims to provide mobile users with advanced and customised services, it becomes apparent that the requirement for intelligent charging and customised billing of service access emerges bravely. In that scope, the enrichment of mobile services with attributes related to user profiles, context, location, presence and other elements providing customization, affects also...

Traditional location-based services (LBSs) determine the current location of a given person or a given set of persons in order to process location-dependent information. That use does not cover the full range that is conceivable for these services. This PhD proposal introduces socalled Zone Services as a new sub-category of LBSs. In contrast to traditional LBSs, Zone Services collect informatio...

Location-Based Services are emerging fast and the problems with privacy are growing with them. While a platform for Location-Based Services can provide the user with high-quality Location-Based Service browsing and powerful mechanisms to reduce the amount of location data transmitted such a platform is dangerous as it has to manage the location data of the users and the actual service usage. Th...

Geographical Information System (GIS) and Global Positioning System (GPS) technologies are expanding their traditional applications to embrace a stream of consumer-focused, location-based applications. Through an integration with handheld devices capable of wireless communication and mobile computing, a wide range of what might be generically referred to as "Location-Based Services" (LBS) may b...

Location-based services for users on the move provide a convenient means of filtering information based on current geographical position. However users also often want to retrieve or capture information associated with past or future locations. We show how new technologies for interactive paper can be used to augment conventional paper maps with location-based services using a combination of us...
