48、S 24.523 version 15.0.0 Release 154 Introduction 4.1 General modelling and relationship to NGN releases A number of different scenarios will likely exist for enabling interactions between Next-Generation Corporate Networks (NGCN) and Next Generation (public) Networks (NGN). The present document desc
49、ribes 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 emerge. 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 to NGCNs and the NGCN users at a number of differ
