47、tion Corporate Networks (NGCN) and Next Generation (public) Networks (NGN). The present document describes a sub-set of these scenarios and the architectural and functional requirements that arise from the support of these scenarios. Future releases may document other scenarios as requirements emerg
48、e. 4.2 Levels of service provision The development of different interaction scenarios based upon the distribution of the hosting of private network capabilities in the enterprise operator and/or in the public NGN operator leads to the concept of the public NGN operator being able to offer services t
49、o NGCNs and the NGCN users at a number of different levels. This concept is further described in ETSI TR 102 478 8. The most basic level of service provision is IP connectivity. Differentiation from the Internet can be in the form of improved or guaranteed quality of service or security. For the purposes of the present document an NGN that provides this level of service acts as a Transport Service Provider (TSP). A second level of service provision is in session establishment and control of communication sessions, e.g. voice, multimedia,
