Current Trends
Transition to all-IP Infrastructure Heterogeneous access:
Wireline: Cable, xDSL, PONs Wireless: WiFi, 3G, Bluetooth, 802.16, Flarion/Qualcomm Trend: Give customers greater bandwidth
Heterogeneous devices: Computers / Laptops / PDAs / Cell phones… Trend: More computing/processing resources (Moore’s Law)
Search for New services & Applications Voice revenues in decline Lack of control of Internet applications Trend: Media-rich, Personalized, Context-Aware

Q&A
Master of Engineering in Telecommunications14
October 6, 2005
What is IMS?
Stands for IP Multimedia Subsystem defined by 3GPP
3GPP’s Service Control Architecture empowered by IETF’s Session Initiation Protocol (SIP) Is not service, but acts as telecom service enabler over IP-based
infrastructure Mandates support of IPv6 (IPv4 optional)
Access-Network agnostic
Enable Fixed-Mobile Convergence and Quadruple-play
Standardized on interfaces and capabilities, not applications
Master of Engineering in Telecommunications15
October 6, 2005
The Needs for IMS
Unpredictable acceptance of new services Quick actions required
Develop and deploy promising services quickly Add resources to successful services on demand Reduce resources for unsuccessful services or remove them entirely on demand
Vertical vs Horizontal solution
Master of Engineering in Telecommunications16
October 6, 2005
The Needs for IMS (2)
Vertical solutions Current solutions of Service providers Issues: Interworking, CAPEX & OPEX, and so on.
Horizontal solutions Generic architecture for diverse applications IMS + IP offer modular, flexible service delivery, and speedy time-to-market
of services
IMS is the answer!!IMS is the answer!!
Master of Engineering in Telecommunications17
October 6, 2005
What IMS Provides to Operators
A common platform with reusable components which provides quick and easy service development
Decreased deployment and management costs
Combinations of the functionalities of each solution
Standardized, open interfaces for 3rd party developers
Value chain control
Master of Engineering in Telecommunications18
October 6, 2005
What IMS Provides to Users
Controllability of a plethora of available IP services
Personalized communications
Single public identity
Consistency of services across operators and access networks (roaming and interworking)
Master of Engineering in Telecommunications19
October 6, 2005
The Evolution of IMS
Early 3GPP Releases (up to Release 4) Only basic IP connectivity
IMS was introduced in 3GPP Release 5
Real-time services mainly after Release 6 IMS Stage 2 WLAN-Mobile Interworking IPv4/6 Migration
Release 7 is work-in-progress IMS Stage 3 IETF Protocol Alignment System Enhancements for fixed broadband access to IMS

IMS Control Layer
CSCF Call Session Control Function
Proxy CSCF (P-CSCF) Acts as the point of entry
Interrogating CSCF (I-CSCF) Acts as Information, topology hiding
gateway Serving CSCF (S-CSCF)
Authorizes each session request by querying HSS
Communicates with AS to perform service control accordingly
Forwards each session request to the terminating network

Conferencing using IMS
1. MRFC & AS act as Conference Focus 2. MRFP acts as Media Mixer
3. Participants & the Focus control the session using SIP
4. All media are mixed at MRFP
5. Mixed Media is multicast or unicast to each participant

IMS Project (Part II) Motivation Network Model for Applicability Analysis Applicability Models of SIP & IGMP/MLD Assessment and Recommendation
Q&A
Master of Engineering in Telecommunications26
October 6, 2005
Motivations IMS Service Control for Video Broadcast and non-SIP
services IGMP/MLD has long been used to trigger multicast
services at Network layer. Internet Group Management Protocol (IGMP) for IPv4 systems Multicast Listener Discovery (MLD) for IPv6 systems
As a step towards the Fixed-Mobile Convergence SIP should be able to do the same thing and more but at
Application layer. To unravel the applicability of SIP & IGMP/MLD focusing
at PEP, e.g. BRAS. Should SIP be used instead of IGMP/MLD? Should SIP still trigger IGMP/MLD? If else, what should we do?

The Model #5
SIP triggers IGMP/MLD to perform its functions at Network layer.
The exception is no IGMP/MLD message is sent.
SIP ACK and its description will be sent to IMS domain as usual.
PEP intercepts and extracts multicast information from SIP ACK and its description.
PEP forwards the SIP message to IMS domain
Master of Engineering in Telecommunications33
October 6, 2005
Recommendations
SIP should be used instead of IGMP/MLD by PEP (e.g. BRAS, GGSN, CMTS)
All intelligence are put within PEP to intercept and retrieve necessary information from SIP messages.
No complicated upgrade mandated for hosts or P-CSCF/PDF.
Master of Engineering in Telecommunications34

Benefits
Reduce redundancy of request
Reduce traffic of signals going into the network (40 bytes/user/time for IGMP and 76 bytes/user/time for MLD)
Improve operators’ controllability of Video broadcast and multicast services
Ease deployment and acceptance process

worldwide as they begin deploying IPTV services and competing
against satellite and cable pay-TV alternatives. ” -- TelecomWeb
“ PCCW represents one of the most exciting success stories in the
global IPTV market and serves as a great role model for other
operators that are considering IPTV services. ” -- LightReading
“ With the world's largest and fastest growing installed base of TV over
DSL subscribers, PCCW's success confirms the business case for
Telco TV .” – BusinessWeek

However... Something is missing !
Re-exam its market entry strategy – Huge customer base doesn’t mean revenue !
Only 58% of the subscribers are paying for the service No installation fee, No compulsory monthly subscription fee A la carte model allows customers to pay for channel by channel , pay-per-view, or
month by monthIt is likely for subscribers pay for only a small amount fee
42% are watching free channels only Free STB and Free channels from PCCW No TV revenue at all !!!
At least 50% revenue is given to content providers
PCCW IS LOSING MONEY !

One of the most open telecom markets in Europe Broadband industry is dominated by DSL Satellite TV companies are the major competitors Free TV channels offered by Freeview and
Free-to-view digital satellite Geographic size is small relative to North
America which enable efficient access network

BT Group – Background
Largest incumbent service provider in the UK BT have over 30 millions exchange lines and
serve over 4 million broadband customers Offer both retail and wholesale services
BT only serves 24% of the broadband consumers in the UK
To launch IPTV service after a full-scale trial that starts in next March
Also announced to use Microsoft TV IPTV edition platform

Observations
The largest telco in the country may not be in the best position to offer IPTV services
BT might deploy IPTV services faster than most North America telcos due to its 21CN network schedule
IPTV deployment is a slow process

Observations on IPTV Equipment Market
IPTV Equipment Market is in Infancy but it is Important for Vendors to be in ILEC’s Suppliers List
Alcatel (Access, Transport and System Integration) and Microsoft (Middleware) Stand out among Vendors
Most of the Incumbent Telecom Vendors can only Play their Traditional Role in Transport and Access
Cable and Satellite Video Head-end, VoD Servers, Set-Top Box Vendors are Entering IPTV Telecom Network
IPTV also Provides Opportunities for New Entrants Targeting Asia Pacific and European Markets First
