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)

Source ISC and TELKOMs Standard System

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)

Next Generation Services
27
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

33
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

Enhanced Services (5)
  • End-user controlled NGN services
  • Services of PABX
  • Premises-based, user controlled VPN
  • Type one and type two Call Center
  • Network Gaming
  • File Sharing
  • Home Monitoring/Control/Manager
  • Content
  • etc.
