Convergence Services Through NGN-CTE on the Multiple Service Provider Environments in NGN

Abstract

The NGN convergence services will play an important role to consolidate the deployment of NGN at the initial phase. At the initial stage, scenario-based approach is expected to act as an efficient way to pre-design before the actual implementation of NGN, the subject for providing the convergence services to the customers. This paper first proposes a deployment model of the NGN convergence services. In this model, NGN-Service Providers (NGN-SP) interact with Service Coordination Function of NGN Service Stratum whereas NGN convergence service terminal equipments (NGN-CTE) provide convergence services to the end users after procedures in End User Service Composition Function. A service composition scenario for the convergence services will be introduced, using the model, to show the usefulness of the proposed deployment model to construct new convergence services on this scenario-based approach.
