Telecom industry changes
Fixed Operators

• Strategies
• Support mobile (UMA)
• Invest in fixed broadband
• New services like IPTV

• Threat
• No upside in fixed business
• Low barrier to entry for BB services

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

Rapid growth of mobile broadband
Enhanced terminal
Succesful Business model
User experience
???????? 20072013 ABI Research

• Web2.0,P2P,UGC technology caused increases of
  internet traffic

• Widget technology enhanced user experience
  improving mobiles interactivity

• Smart-phone with buildtin web browser
• Laptop with built-in HSDPA

Traffic growth is not linear with revenue

FMC impacts

• Fixed Mobile Convergence includes
• Network convergenceMulti-mode terminal access
  to converged network Reduce CAPEX
• Service convergenceSeamless user experience
  over heterogeneous networks Enhance ARPU
• Operational convergenceCommon 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
Synergy between services
Main Driving Forces

• Broadband services anywhere, anytime
• Technology usability, more user accessible
• Access transparent to the user

• 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 access to PS service
Unified account bill
Unified authentication
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
  (TC3network 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, S-CSCF, MP-CSCF, FP-CSCF,
SBC, MGCF, MGW...
Interfaces protocol specifications
The Cx, Dx, Shinterfaces 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.

• Rel9/10
• SAE 23.402 covers many access based on bear layer
• BBF access interworking will be an important WID
  in Rel10-11.

• Rel7/8
• Many RATs access to IMS
• Including xDSL?PON?Cable
• Common IMS is being considered.

• Rel6
• Start to study interworking between 3G and WLAN
• I-WLAN/WLAN mobility
• IMS was studied

• Rel4/5
• Initial standard specification works for mobile
  network.
• Including UE, RAN and CN.

2000-2003
20032005
20072010
20052007
3GPP has developed a good technical foundation
for FMC.

Vision become a Real technology convergence?
Key technology
Current SODs status
NGMNconsider the collaboration between
SDOs. TMFfocus on OAM work for fixed network and
3GPP SA5 focus on mobile area. BBFconsolidate
the fixed standard resource. Femto Forumenhance
Femto feature to have more reliabity within fixed
network. HGI,ITU-T,IEEE
UMA/GAN/IWLAN Common IMS SC/ICS/VCC Femtocell/offl

• 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?
