Question 6/13 - NGN mobility and fixed-mobile convergence
(New Question)
- Motivation
The origin of NGN is within fixed networks and their evolution. However, increasingly mobility
services are demanded by the user and the operators. Therefore the support of several aspects
of mobility is a feature to be provided by NGN. This shall also include “discrete mobility” which
can be offered even based on fixed line access technologies. In addition, there is the requirement
for fixed-mobile-convergence which includes convergence of the services, convergence of the basic
architecture of NGN and Mobile Networks etc. These requirements are the basis of this Question.
The NGN focus is mainly on broadband communication with mobility as an inherent feature although
it should not be confused with genuine mobile networks where all terminals access the network using
the wireless interface.
For the NGN work in ITU-T it is essential to have a clear focal point for mobility related issues
of the NGN, which is especially well connected to the mobile network standards bodies.
This should enable the ITU-T to provide value by rapidly enhancing the NGN recommendations to
provide elements of mobility and extend the mechanisms to fully suit the requirements on NGN.
- Question
Study items to be considered include, but are not limited to:
- Service convergence and interoperability between fixed and mobile networks
- Architecture convergence between fixed and mobile networks
- Nomadicity (discrete mobility) within the NGN and possible roaming between fixed and mobile networks.
Note: Wherever possible, previously defined mobility mechanisms, will be reused within course of this question.
- Tasks
Tasks include but are not limited to:
- Draft Recommendations on converged services for NGN, based on services developed for mobile networks, and a selection of mobility architectures and mechanisms and their use in NGN
- NGN Maintenance of existing mobility documents of the NGN series.
- Relationships
Close cooperation within Study Group NGN, since several questions will deal with mobility aspects, and with other ITU-T Study Groups (for services and applications) and other organization must take place
Questions: Questions dealing with mobility aspects
