Fixed Mobile Convergence

• A clear trend is emerging in the form of FMC - A
  fixed and mobile telephony convergence. The aim
  is to provide both services with a single phone,
  which could switch between networks ad

Triple Play

• Triple Play is a marketing term for the
  provisioning of the three services over a single
  broadband connection1.
• High-speed Internet,
• Television (Video on Demand or regular
  broadcasts) and
• Telephone service over a single broadband
  connection.
• Plus. Wireless Services gives you a Quadruple
  Play
• Triple Play services are offered by
• cable television operators
• telecommunication operators.
• Triple Play focuses on a combined business model
  rather than on solving technical issues or a
  common standard.

This presentation will explore strategies
towards achieving telecom convergence

Internet ProtocolThe Transport Network for
Convergence

• Internet Protocol (IP) is a packet-based
  protocol.
• Packets take different routes through the
  network, and can arrive at different times.
• Higher traffic increases network delays.

• Different services have different tolerance to
  network delays
• Network delays are tolerable for data
  services (e.g. file transfers, email, or music
  downloads).
• However, interactive voice and video services
  require real-time response.
• Optimizing IP network design is important for
  converged IP services.
• The generic Internet has limited (if any) ability
  to ascertain voice and video packets, hence
  quality varies signficantly.
• Carrier IP networks improve use additional
  techniques, including using Multi Path Label
  Switching (MPLS), to transmit delay-sensitive
  packets with higher priority and dedicated
  capacity.

Legacy TDM Network

• Services delivered as stand-alone Service Nodes
• Each Service Nodes often has their own
• Proprietary architecture
• Management systems and service databases
• Often tied to a access network subset
• Resulting characteristics and operational
  limitations
• Multiple systems and databases to manage
• Voice only -gt complex interworking with IP-based
  data services
• New service introduction complex and slow

• Service Nodes decomposed into
• Application logic and
• Media processing.
• Application logic executes on off-the-shelf
  servers.
• Media processing is shared across many services.
• Interconnection through open standards-based
  interfaces.

AdvancedTCA (ATCA) Common Reusable Platform

• ATCA is a hardware platform specification for
  telecom equipment manufacturers.
• Enables manufacturers to design plug-compatible
  equipment and components that work together.

• Provisionable ATCA Cards for
• Network Processing,
• Digital Signal Processing (DSP),
• Data Processing,
• Switching,
• Storage
• etc.

Common ATCA Hardware Chassis
Reusable Platform Provisionable For
ManyTelecommunication Applications

• OS and
• System S/W
• High Availability
• Platform Management
• Security
• etc.

Conclusions

• Convergence often described as business models
  and end-device experience
• However, to achieve convergence requires
  rethinking service delivery in the core network
• Strategies towards Telecommunications
  Convergence
• Core Network Convergence
• Everything over IP (Internet Protocol)
• Access Network Convergence
• Mapping any Access/Device to IP using IMS
• Service Delivery Convergence
• Decomposed Services Approach for Voice/Video over
  IP
• Mapping Any Service to IP using IMS
• Hardware Platform Convergence
• ATCA Platforms provide flexibility for any IMS
  application
