LoL@: a UMTS location based service

UMTS is expected to offer a powerful environment for location based multimedia services. We have specified such a service, using the packet switched domain of UMTS and overlaying standards like SIP and OSA/ Parlay. LoL@ (Local Location Assistant) is a showcase for future UMTS services and their requirements. It proposes an architecture for location based multimedia services, including advanced user interface concepts with speech recognition and central user preference management. It explores the potential of the standards and shows were improvements are necessary.
