>> Study Group 13 : Next Generation Networks
Question 10/13 – Interoperability of satellite with terrestrial and Next Generation Networks (NGNs)
(Continuation of Question 13/13)
- Motivation
Satellite networks with their global coverage should be considered as complementary to the terrestrial infrastructure. As such the Next Generation Network (NGN) architecture and interworking should consider satellites.
Satellite Network Architectures to interoperate with terrestrial and next generation networks for different scenarios such as Broadband/mobile access, Multicast, Broadcast and other services are of interest.
Satellites can be a means to bridge the digital divide and contribute to the establishment of the world information infrastructure. They are also to be considered for customers from developed countries. Global standards are required to ensure the interconnection and interoperability of satellite and terrestrial networks. Of particular interest for the satellite-terrestrial interoperability are architecture, mobility, QoS, multicast, broadcast and security.
This question will also identify existing ITU Recommendations that require improvement and revision in order to better interoperate with satellite systems. This effort will focus on ensuring established performance objectives do not preclude satellite systems.
- Question
Study items to be considered include, but are not limited to:
- Satellite-Terrestrial/Next Generation Networks (NGN) Architecture
Develop architecture and reference models that integrate satellite systems with terrestrial and next generation networks.
- In which scenarios do satellites complement the terrestrial and next generation networks?
- How is the interworking of satellite and terrestrial/next generation networks for the different scenarios?
- Hybrid Satellite-Terrestrial Next Generation Network (NGN) Performance
- How will the end-to-end QoS objectives for IP-based services be achieved when satellites participate in the communications?
- How will DiffServ and IntServ interwork with satellite networks?
- What additional information should be specified to meet the objectives in Recommendation Y.1541?
- Satellite Multicast
Specify network capabilities and functions of hybrid satellite-terrestrial networks for Multimedia Multicast environments.
- Satellite Broadcast
Specify network capabilities and functions of hybrid satellite-terrestrial networks for Multimedia Broadcasting environments.
- Security for hybrid Satellite-Terrestrial/Next Generation Networks (NGN)
Study security related issues for hybrid satellite-terrestrial/next generation networks. This question will address requirements, architecture, interfaces etc.
- Tasks
Tasks include but are not limited to:
- Finalizing Draft Recommendation on Satellite-Terrestrial Networks Architecture (Y.SatIP_arch)
