scope:

The objective of this Recommendation is to identify impacts on networks which are connected to the IPv6-based NGN, and to describe the relevant scenarios/models in order to identify the functional requirements.

NGN transport stratum functions provide a series of transport and transport control functions that support the service stratum features. In IPv6, some mechanisms have been already introduced to support both transport and transport control functions in order to perform the access to the IPv6- based NGN. Along with IPv6, the devices in network also have relevant functional requirements. This Recommendation covers:

- identification of the impact on networks which are connected to IPv6-based NGNs;

- network access scenarios specific to the NGN, including parameter configurations such as prefix, address and server configurations;

- scenarios of access network level registration in IPv6-based NGNs;

- functional requirements for networks which are connected to IPv6-based NGNs.
