A summarizing the CTO's shows a lot of commonality: in particular, focused on the need to develop and deploy the integration and interoperability of IP-based and PSTN network services and applications. Some people refer to these networks as "next generation networks" or "NGN". The NGN is by the following fundamental characteristics:

• Packet-based transfer
• Separation of control functions among bearer capabilities, call/session, a nd application/ service
• Decoupling of service provision from network, and provision of open interfaces
• Support for a wide range of services, applications and mechanisms based on service building blocks (including real time/ streaming/ non-real time services and multi-media)
• Broadband capabilities with end-to-end QoS and transparency
• Interworking with legacy networks via open interfaces
• Generalized mobility
• Unrestricted access by users to different service providers
• A variety of identification schemes which can be resolved to IP addresses for the purposes of routing in IP networks
• Unified service characteristics for the same service as perceived by the user
