NGN Concept and Definition

• Multi-service network
• Voice,data,video
• Hierachy topology
• Network service layer,control layer,media
  layer,transport access layer
• Open interface
• H.248, SIP, MGCP
• Packet mode technology
• IP/MPLS support
• QOS
• A network with guaranteed QoS for different
  traffic types and SLAs
• NTC definition
• For interconnection between all operator in
  national (continue)

NGN Network Element (Cont.)

• Access Gateway
• - Allows the connection of subscriber to the
  packet network.
• - Converts the traffic flows of analogue signal
  to packet network..

14
NGN Network Element (Cont.)

• Trunking Gateway
• - Allows interworking between TDM telephony
  network to
• packet-based network.

15
NGN Network Element (Cont.)

• Softswitch
• - Referred to as Call Agent or Media Gateway
  Controller (MGC)
• provides the service delivery control within
  the network via
• H.248 protocol,sip protocol
• - Performs signalling gateway functionality for
  interworking with
• PSTN N7 signalling network.
• - Provides connection to Intelligent Network or
  Applications
• Server (AS) to offer another services

16
NGN Network Element (Cont.)

• Applications Server (AS)
• - Support service execution, e.g. to control
  call server and
• NGN special resources (e.g. media server,
  message server)
• via these protocol H.248, SIP, SS7, ENUM,
  MPLS,
• BGP etc.

• introducing SHLR concept in fixed network
• Learning from mobile and IMS-oriented network
  architecture
• Enhancement of the network wide service
  capability

25
Conclusion

• NGN has implemented and put into service for
  TRIPLE T Broadband in TTT Group launched In
  Upcountry and BMA .
• Service Offerings Maxnet (high speed internet)
  VoIP services and future multimedia convergent
  services.
• The PSTN network replacement Plan by NGN are
  settled for TTT in future plan.
• The international gateway for TTT Global net
  also implemented by NGN.
