Aggregation of composite location-aware services for mobile cellular networks

Abstract

The introduction of context-aware services through service frameworks such as Open Service Access gateways in 3rd Generation networks has coincided with the increasing popularity of Business to Business (B2B) solutions such as Web Services. It is envisioned that B2B characteristics, such as service aggregation will play a part in deploying location-aware services in 3G networks. This paper examines and explores the suitability of service integration models, possible business models, the technical requirements, and suggests a framework for the aggregation and deployment of aggregated composite location-aware services. A prototype of the framework was developed and experiments involving J2EE based and Web Services/SOAP based composite services were conducted and elaborated in the paper. An analysis of the experimental results is presented at the end of the paper. © IFIP International Federation for Information Processing 2003.
