A study of Location-Based Services including design and implementation of an enhanced Friend Finder Client with mapping capabilities

Abstract [sv]

Detta arbete behandlar mobilpositionering och relaterade tjänster, så kallade location-based services. Syftet med arbetet är att undersöka hur mobilpositionering kommer att utvecklas i takt med att nya mobilsystem tillåter mer avancerade mobila tjänster. En applikation, Finder Client har utvecklats för att kunna visa vänners positioner på en handdators karta. Kartorna som används finns i färdiga ruttplaneringsprodukter som installeras på handdatorn. Positioneringen sker via en GSM-telefon och SMS. Syftet är även att visa att man kan spara data på handdatorn för att göra intelligentare applikationer. Utvecklingen har gjorts i OPL för en Psion 5mx handdator. OPL är inbyggt i Psion och liknar språk som Pascal och Basic. Slutsatsen är att det går bra att utveckla en Finder klient för handdatorer men det vore mer användarvänligt att utveckla den för en kombinerad handator och mobiltelefon, en så kallad Smart Phone. Man kan också tänka sig att GSM-positionering blir en del av ett ruttplaneringsprogram precis som GPS-positionering är idag. En marknadsundersökning har utförts i examensarbetet. Det kan konstateras att en kombination av GSM- och GPS-positionering kommer troligen att vara lyckosammast i framtiden. De drivande krafterna inom mobilpositionering är den amerikanska statens påbud att alla mobiltelefoner ska kunna positioneras vid alarmsamtal (E911) samt att mobiltelefonoperatörerna ser tjänsterna som en ny potentiell inkomstkälla. Det är mycket svårt att säga vilka tjänster som kommer att bli populära i framtiden. Lösningar som riktar sig till ungdomar, underhållningsbranchen och mot att navigera/spåra fordon ser dock mycket intressanta ut. Det är troligt att positionering kommer att utgöra en liten del i många framtida mobila tjänster. ABSTRACT This work deals with the aspects of location-based services. The aim is to investigate how mobile positioning is going to develop in relation to the fact that new mobile system allows more advanced mobile services. An application, an enhanced Finder Client is developed. It uses maps to display friends’ positions on a handheld computer (PDA). The maps are off-the-shelf route planning products that are installed on the PDA. The positioning is made using a GSM mobile phone and SMS as a means for communication. The aim is also to show that it is possible to store large amounts of data on the PDA to make more intelligent applications. The development is performed in OPL on a Psion 5mx handheld computer. OPL is Psion’s built-in programming language, quite similar to languages like Pascal and Basic. The conclusion is that it is possible to develop a Finder Client for handheld computers but it would be more user-friendly to develop the client on a combined mobile phone and a PDA: a Smart Phone. It can also be possible to incorporate GSM positioning into the map software just as GPS positioning is a part of them today. A market overview has also been performed. The conclusion is that a combination of GSM and GPS positioning is probably the most successful solution for the future. The driving force is the Federal Communications Commissions, FCCs E911 decree, which regulates that all emergency calls from a mobile phone must be able to be positioned. Another aspect is that the mobile operators consider location-based services to be a new source for income. It is difficult to estimate which solutions that are going to be popular in the future. Services focusing on the youth, entertainment and vehicle navigation/tracking seems however to be the most interesting. It is likely to believe that mobile positioning is going to be a small part in many mobile services in the future.
