Operating System

This report describes the motivation, background information, experiments done and problem encountered by our group in participating in the final year project related to using GSM cell information for location-based services over Symbian operating system. The report would firstly introduce the Symbian OS, the major operating system used in mobile phone nowadays, in the aspects of highlighted features specific to mobile phones. Following is current role of location-based service, LBS in short, which is a highly demanding service in the fields of emergency, navigation and information distribution. The next step is to show different kinds of general positioning methods, including signal attenuation and time of arrival (TOA), as well as current LBS technologies. These three components would play important roles in our project. Due to the complicated network design, expensive hardware and telecom company dependency, general users would not have the initiatives to try ou

Location-based Services using GSM Cell

This project is subjected to the final year project LYU0301. The project title is “Location-based Services using GSM Cell Information over Symbian OS”. This report contains ten chapters. They include the introduction of this project, the introduction of Symbian OS, some basic GSM technologies, currently existing LBS solutions, location-based service using location area identifier (LAI) and cell identifier (CI), LBS in the 2-dimensional space, LBS in the 1-dimensional space, the middleware architecture and its component. Our final year project tries to make use of LAI and CI to provide location-based service in 2-dimensional and the 1-dimensional space using simple hardware which is going to be widely distributed in the near future- mobile phones with Symbian OS. We also created a middleware for developing location-based application using our approach in LBS. This middleware includes a set of APIs and tool kits. This report also includes two test on the middleware developed. We tried t
