Core NGN Subsystems
ATIS does not specify that the NGN must support all access technologies
Network service enablers were defined as network-based communications services that bring value to consumer applications
Key capabilities for Release 1 NGN
endorses the IETF Presence model
Personal profiles & Personal Information Mgmt complement Presence, to link services and enable end-user centric model
Ability to link and unify various identities is a foundation for many other NGN services
End-user centric model will enable significant new service opportunities
ATIS Security Focus Group has completed a detailed gap analysis and prepared a work plan to address these gaps. Topics addressed include:
Significant revenue generation and cost savings opportunities must justify the substantial investment required to build the NGN.
The NGN must facilitate running a business with the efficiency of WalmartTM and the brand differentiation of Coca-ColaTM.
Service delivery complicated by increased number
of sophisticated interfaces.
User-specific, location-agnostic services
differentiate product offering.
Focus of NGN is converged user-centric Voice & Data services, irrespective of the access & transport technologies used or deployed
Objective is to support high-quality ETE revenue generating service — securely and seamlessly — to the customers, e.g., a handoff for a wireless handset roaming between a wireless and wireline infrastructure without degradation of quality
