Telecom industry changes:
Fixed Operators
Threat
• No upside in fixed
business
• Low barrier to entry
for BB services
Strategies
• Support mobile (UMA)
• Invest in fixed broadband
• New services like IPTV
Mobile Operators
Threat
• Market maturity
• Price-based
competition
• Data consumption
Strategies
• Fixed-Mobile Substitution
• Bandwidth pricing
• Mobile Bitpipes
• Content via mobile portals
Multi service
Threat
• Combined fixed and
mobile threats
Strategies
• Fixed-Mobile Convergence
• Content ownership
• Unicast and broadcast
• Home Gateways

FMC impacts
 Fixed & Mobile Convergence includes:
• Network convergence：
Multi-mode terminal access to converged network
Reduce CAPEX
• Service convergence：
Seamless user experience over heterogeneous networks
Enhance ARPU
• Operational convergence：
Common OAM, consolidation of operational departments
Reduce OPEX
TCO reduction will be the main objection for FMC.
Driving forces for FMC
Synergy between access
• Broad variety of access technologies
• No single “perfect” broadband access
technology for all conditions
• Wireless mobility support
• Wired support for high bandwidth
Improved user experience
• Broadband services anywhere,
anytime
• Technology usability, more
“user accessible”
• Access transparent to the user
Main
Driving
Forces
Synergy between services
• Same service anywhere, anytime,
on any access
• Best service on optimal access,
according to network availability,
user subscriptions
Maximize return on network
investment
• Different services/quality for different users
• Increase utilization of data services
• Flexible bandwidth management
ALL-IP network, Mobile Internet are the key foundation for FMC.
Highlights on FMC Standards : CCSA

FMC requirements are beginning more and more stronger and clearer after the
recombination of Chinese operators in 2008. 3 operators are eager to have the
clear specifications to provide full services to customers to enhance users
experience and ARPU.

China communication standard associations (CCSA) is very active in FMC related
standard work and has done a lot of work since 2006. Some collaboration
between CCSA and 3GPP was initiated.

FMC requirements in CCSA:
Unified
account & bill
Unified
authentication
Unified
access to
PS service
CCSA active and has done a lot of work in FMC area.
Highlights on FMC Standards : CCSA

Unified IMS is the CORE service control layer for FMC, so CCSA put much
resource on this work.

A joint technical committees was built in 2007 and many specifications has been
completed in 2009, since the different technical committee focuses on fixed and
mobile areas respectively (TC3:network and switching & TC5: wireless network).
General technical requirements
The requirements of unified IMS, The functionality & architectures of unified IMS
The networking of unified IMS, The security of unified IMS
Equipment specifications
The equipment standards for each unified IMS including HSS, I-CSCF, SCSCF, MP-CSCF, FP-CSCF, SBC, MGCF, MGW...
Interfaces & protocol specifications
The Cx, Dx, Sh…interfaces and the SIP protocol, BICC interworking
with SIP.
FMC service requirements, common policy control, unified voice… are
also being studied in CCSA.
Highlights on FMC Standards : 3GPP
As a partner of 3GPP,CCSA has
submitted lots of contributions.

2007~2010
3GPP has developed a good technical foundation for FMC.
Vision become a Real technology convergence？
Current SODs status
NGMN：consider the collaboration between
SDOs.
TMF：focus on OAM work for fixed network and
3GPP SA5 focus on mobile area.
BBF：consolidate the fixed standard resource.
Femto Forum：enhance Femto feature to have
more reliabity within fixed network.


2010Q1, a FMC workshop was held by 3GPP and BBF and almost all the
Tier1 operators and vendors joined in this workshop and some agreements
were endorsed.

2009Q4, 3GPP SA5 and TMF pushed 2 OAM work items and a joint meeting
was held in 2010.5.
The Vision for network convergence is getting clear？
Or the overall convergence direction is getting clear?
