Scenarios of:

Hosted enterprise services and business trunking (application level)
Roaming
For each scenario, involved entities, emergency calls, provisioning, security, charging, and transport control
: NGN hosts com capabilities for business users directly attached to an NGN. enterprise and corporate services as IMS applications hosted in the NGN operator's network on behalf of an enterprise
architecture and procedures
Eg: break-in and break-out
: NGN hosts transit capabilities betweens NGCNs + optionally additional applications such as break-in/out and bulk rerouting
Architecture and procedures
- Subscription based approach (NGCN connected to P-CSCF, each NGCN has a service subscription to IMS with 1 entry in UPSF)
peering-based approach (NGCN connected to IBCF)
virtual leased lines (at session level): NGCN sites interconnected thru an NGN

14. ETSI TISPAN IPTV Overview
TISPAN Release 2 introduced IPTV to the NGN architecture: Broadcast TV, Content on-Demand, Network-PVR
TISPAN Release 3 adds new kinds of services by combining NGN features (voice, data, presence, messaging, community, IPTV) :
User generated content
User recommendations
Personalized channel
Personal service composition
Content personalization
Shared service control
Ongoing work: CDN, P2P
Targeted advertising
Messaging
Push CoD
Advanced PVR
IPTV Roaming / Mobility
Media Synchronization
CDN: Content Delivery Network
P2P: Peer to Peer
PVR: Personal Video Recorder 14

Triple Play bundle
Why IMS-based:
Allows integration of IPTV flows into bundled service packages to expand market and increase customer interest
Reuse well standardized IMS components to enforce IPTV control, e.g. registration & authentication, multi-user identity, session control, real-time billing, QoS, NASS/RACS.
Enable enhanced and converged services (Caller ID on screen, personalized TV, chat on view, friends TV, …)
Enables convergence, access agnostic of different type of access networks, service continuity across devices…

Integrated IPTV
Note: this is the first global approach for standardizing a CDN
ETSI TISPAN, which is working on IPTV standardisation is currently defining the Content Delivery network.
On left hand side, service provider and home network have been defined for an IPTV service.
On the right hand side, this is their current work: services requirements, functions, architecture and procedures for the CDN.
So far, the work is led by telecom operators.

18. TISPAN Study: Operator-managed P2P for IPTV
No operator involvement
Full operator involvement
Degree of network operator involvement in P2P content delivery
Pure “Over-The-Top” (OTT)
Network-Based Access Control
(NBAC)
P2P-based operator content service
Operator-internal P2P-based CDN
Deep Packet Inspection
(DPI)
Peer for peer
(P4P)
Peer-to-Peer technology can be applied in many ways, with zero or however significant operator interaction.
TISPAN is currently considering if operator-managed P2P communication could assist in efficient operations,
by keeping a lot of content re-distribution at the edge of the network.
