ConvergenceWhat does it mean?

• Convergence of voice, data and Internet into one
  seamless IP-based communications network
• Adopting IP as common platform to plug in
  unlimited variety of applications and services,
  cost effectively
• Enabling broader choice of devices for customer
  services provided over common platform
• Unlocking content (voice, data, video, text,
  commerce, etc.) so it can flow seamlessly among
  applications

NGN Architecture

• Management Plane, gives Operation System Support
  (OSS) function
• Transport Plane, as transport media for all
  message in the network
• Call Control Signaling Plane, as connection
  process handler
• Service/Application Plane , as supplier and
  executor of application (telephony, data,
  multimedia, include Features)

Next Generation Network Softswitch System

• Softswitch system is a part of next generation
  network based on ISC/IPCC reference model consist
  of Softswitch host, Application Server, OSS,
  Signaling Gateway, Trunk Gateway and Access
  Gateway.
• Softswitch (call agent / call controller) as call
  control function
• Application Server (AS) provides enhanced
  features which is not available in Softswitch
  host.
• Operating Support System as network management,
  billing support, etc.
• Signaling Gateway (SG) as interface to CCS-7
  (STP)
• Trunk Gateway (TG) as interface to TE or LE of
  PSTN
• Access Gateway (AG) as interface to CPE

20
Softswitch Protocols

• SIP-T inter softswitch protocol
• Media Gateway protocol
• MGCP
• Megaco (H.248)
• Softswitch VoIP protocol H.323 (Min. ver 2)
• Application Server and SIP phone protocol SIP
• OSS protocol SNMP
• Billing Server protocol FTP atau TFTP
• Trunk Gateway has to support CODEC
• G. 711
• G. 729
• G. 723

21
Challenges to Consolidate Network

• Integrating existing network will be controlled
  by softswitch
• VoIP Network, Call Manager Consolidation
• DSLAM, Running as Access Gateway
• RAS, Running as VoIP Gateway
• CaTV network, Softswitch Implementation in HFC
  Network
• PSTN, PSTN preparation to enable Softswitch
  implementation (reduce node for CCS-7 penetration)

Key Atribute NGN Service Architecture
28
NGN Service Characteristics

• Ubiquitous, real-time, multi-media communications
  
• More personal intelligence distributed
  throughout the network
• More network intelligence distributed
  throughout the network
• More simplicity for users
• This shields users from the complexity of
  information gathering, processing, customization,
  and transportation.
• Personal service customization and management
• Manage personal profiles, self-provision network
  services, monitor billing information, customize
  user interfaces behavior of their applications,
  and create and provision new applications.
• Intelligent information management
• To manage information overload to search for,
  sort, and filter content, manage messages or data
  of any medium, and manage personal information
  (e.g., calendar, contact list, etc)

29
Basic Telephony Services

• Basic Services (e.g. ISDN bearer services and
  ISDN tele-services)
• Supplementary Services (e.g. CLIP, CLIR, CW)
• IN-Services (e.g. shared cost, premium rate, free
  phone and personal number)
• Value Added Services (e.g. Voice Messaging and
  Voice Mail, Audio/Video Conferencing, Calling
  Card and Directory)
• Circuit Switch Based Services (e.g. OCB)
• GSM Services (e.g. Voice, SMS)
• Interconnection Services (e.g. Origination,
  Termination, unbundled access, Carrier Selection,
  collocation)
• Services arising from open competition (e.g.
  collection, third party billing, clearing house,
  enquiry services)
• Transport services (e.g. Leased-line, ATM, and
  frame relay services)

30
Enhanced Services (1)

• Users roaming from one access network to another
• The ability for users to manage their personal
  profiles
• Self-provisioning network services
• Monitoring of usage and billing information
• Users customizing their own interfaces etc.
• Making and receiving voice calls whilst using a
  data application without dropping out of the data
  application.

31
Enhanced Service (2)

• NGN call centers
• Full integration of communication applications in
  workflows
• Multimedia, multi-channel interaction
• End-users can call when, where and how they
  choose
• Completely network-based virtual call centers
  that queue and route calls directly to individual
  agents throughout the world, without the need for
  any other call center platforms Call Center
  On-Demand

32
NGN call centers Architecture

Enhanced Services (3)

• NGN multimedia conferencing

• NGN multimedia conferencing is a kind of
  ubiquitous, real time, multi-media communication.
  High-speed access and transport allow for natural
  interactions between users and the network.
• NGN multimedia conferencing not only allows
  multiple parties converse with each other while
  displaying visual information. In an NGN
  environment also the Internet/database access may
  be strongly involved in a communication.
• NGN makes multimedia conferencing on-demand
  possible.

34
Enhanced Service (4)

• Unified Messaging
• Allows more simplicity for users by a unified
  environment for all forms of communication.
• Unified Messaging means the delivery of voice
  mail, email, fax mail, SMS, MMS as well as paging
  through common interfaces independent of the
  means of access and terminals.
• With NGN users will be encouraged to use Unified
  Messaging, because the usage of that will become
  easier.
• Enhancing Unified Messaging solutions with more
  advanced capabilities by adding the real-time and
  multimedia components
