NGN Concept

• NGN is a concept for defining deploying
  networks, which due to their formal separation
  into different layers planes and use of open
  interfaces, offers service providers a platform
  which can evolve in a step-by-step manner to
  create, deploy manage innovative services.
• NG Architecture Service oriented, layered
  (transport, control,
• application)
• NG Services Converged (quad play- voice, data,
  video mobility)
• NG Access High speed (Broadband) IP based
  connectivity
• (ADSL,VDSL, WiMax, Cable TV, FTTH)
• NG Transport Ethernet, IP-MPLS, RPR, T-MPLS
• NG Mobile 3G, 4G
• NG Internet IPv6
• NG Interconnect Capacity and Quality based
• NG Licensing Unified, Converged

FMC-Business Drivers

• Many households today have at least one cell
  phone.
• In these households estimated 60 of long
  distance calls and 36 of local calls take place
  on mobile phone at home (Yankee Group)
• 14 of users use cell phones as their primary
  line (Yankee Group)
• Additional 26 of users are ready to switch as
  in-building coverage improves
• Over 50 of users place mobile calls when they
  are at home or office (Wireless Review)
• WiFi exists or can be supported in both places
• Traffic on mobile network has been increasing
  causing QoS problem and hence subscribers churn
• Pressure to reduce tariff for voice services
• Fixed broadband availability is growing at a
  rapid pace - double digits in most cases
• VoBB provides new revenue stream for Service
  Provider, and also
• give a low cost alternative to carry mobile
  voice traffic
• Leverage low fixed line asset cost to support the
  mobile voice application
• Users need to access services seamlessly
  regardless of their
• location, active device or the network access
  method
• Lower CAPEX, Lower OPEX, Higher coverage and
  quality

12
Driving Forces

• Consumers like mobile phones
• And all of them are not using just for mobility
• In gt50 cases used for portability, not mobility.
  
• Consumes demands low cost for voice
• Broadband is getting widely deployed
• Voice over broadband is not only new revenue
  stream for SP, but also the low cost alternative
  to carry mobile voice traffic
• Leverage low fixed line asset cost to provide the
  mobile voice application
• Lower CAPEX, Lower OPEX, Higher coverage and
  quality
• gt Fix Mobility Convergence

13
With FMC, users can access the best available
service whether they have mobile coverage (e.g.
GSM, CDMA), Wi-Fi/fixed-line coverage (e.g.
Wi-Fi SIP over broadband) or a combination of
both.

No Impact to Existing Networks

• To Existing NGN Networks
• A functional module addition to the existing
  SoftSwitch and backend application
• Able to use the existing NGN for call processing
  and routing
• Normal NGN users are still served by existing
  infrastructure
• Zero impact of the FS addition
• All (home/visiting) FMC users will be served by
  the FMC-FS
• Registration, authentication, roaming, call
  processing, handover
• FMC-FS requires access to FMC user profile data
• HSS (Home Subscriber Server) model of IMS
• To Existing GSM Networks
• GSM Homed FMC users appear to be regular GSM
  users
• NGN Homed FMC users appear to be visiting GSM
  users
• FMC-FS uses standard roaming Interface to the GSM
  Network

• How to increase the ARPU leveraging NGN/IMS?
• IPTV? FMC? Triple-play? Quadrupled-Play?
• How to lower the OPEX?
• Real estate expense in the big metropolitan area?
• Power consumption?
