A business view for NGN service usage

Next generation networks are expected to deliver services tailored to all users, hence next generation services are moving toward user centric services, relying on multiple cooperating service platforms. To accomplish successfully the usage continuity between these user centric services, we need to model the link between the service as perceived by their end-users and the service platforms involved in the service implementation. Including the studies on services from ETSI and ITU-T with the concepts of the TMF, we propose a service business modeling approach to optimize NGN services architectures.
