Abstract

Mobile Location-based Services (LBS) answer three important questions: Where am I? What's around me? How do I get there? The recent convergence of Internet, wireless communications, mobile positioning and Geographic Information Systems (GIS) has given rise to a new class of location-based services. Locationbased services are complex and require the integration of many different technology components into one seamless system. The three main components required to construct a location-based service are the location service application, the location server and the device application to deploy the whole system on mobile wireless network. This thesis has provided three important components to extend the capabilities ofUser Location Service on BT's Erica application platform. Firstly, a location server simulator, which processes the location request, returns simulated positioning data to the location service application. The interface is modeled after the Mobile Location Protocol (MLP) specified in Location Interoperability Forum for Standard Location Immediate Service. The simulator enables third party providers to quickly implement an end-to-end location-based solution within their enterprise. It helps to remove the necessity for testing location applications against live and charged services. An admin website is designed for easy management of positioning data used by the simulator. Secondly, a location service application, which is aimed at providing mobile users the map of their current position. The location service application serves as 'middleman', which enables the mobile users to get the location data from the simulator. The main reason for building this service application is to confirm the reliability of the simulator when the third party providers validate their applications in a test environment prior to connecting to the real mobile network. The last component is a small software entity that runs on wireless Java MIDP mobile phones such as Motorola A835, Nokia 7 610, SonyEricssonP900 and so on. This component is called device client, which issues a location request that starts the data flow and supports map or response messages visualisations on mobile devices. This project is crucial to support of BT's launch of LBS in User Location Service on ERICA platform through supporting the testing and validation of the platform components. It has identified the most appropriate communication mechanism for delivering location data to the new generation of smart phones such as Symbian, J2ME and others. Besides that, it has also defined the issues, barriers and opportunities to the deployment of device based LBS applications.
