2 Agenda NGN Concept and Definition NGN Network Element
Network Architecture towards NGN NGN Network Element Technical Standard for NGN Network Connection following NTC. Strategy for implement NGN

3 NGN Concept and Definition

4 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)

5 NGN Concept and Definition (Cont.)
NGN หมายถึง โครงข่าย Next Generation Network ซึ่งเป็นโครงข่ายโทรคมนาคมแบบแพ็กเกตที่สามารถให้บริการสื่อสารโทรคมนาคมและบรอดแบนด์ที่หลากหลายรูปแบบ สามารถใช้เทคโนโลยีการส่งผ่านข้อมูลที่ให้คุณภาพบริการ มีฟังก์ชัน (function) การให้บริการแยกเป็นอิสระจากเทคโนโลยีการส่งผ่านข้อมูลที่รองรับ ผู้ใช้บริการบนโครงข่ายโทรคมนาคมแบบ NGN สามารถเลือกใช้บริการใดๆ จากผู้ให้บริการรายอื่นๆ โดยใช้เทคโนโลยีเชื่อมต่อปลายทาง (access) ใดๆ ได้โดยไร้ขีดจำกัด โครงข่ายโทรคมนาคมนี้รองรับการใช้บริการแบบเคลื่อนที่ (generalized mobility) ได้ทุกที่ทุกเวลาอย่างต่อเนื่อง (consistent and ubiquitous)

13 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.

17 Technical Standard for NGN Network Connection following NTC.

18 Technical Standard for NGN Network Connection following NTC.

19 Technical Standard for NGN Network Connection following NTC.(Cont.)
โครงข่ายโทรคมนาคมแบบ TDM

20 Strategy for implement of NGN
NGN Total Solution NGN Strategy for fixed Network NGN application for Triple Play Solution Pre-IMS: Smart Network Solution

22 NGN Strategy for fixed Network
Replace out-dated equipments Bring voice additional value Bring broadband additional value SoftSwitch Centralized Database AG TG TG DSLAM IP SDH / MSTP RTU AG AG IAD Aged subscriber lines acquire new technology. Remaining PSTN Broadband is not pipeline any more !

23 -Advantage : for customer for single contact & payment

25 Conclusion NGN has implemented and put into service for TRIPLE T Broadband in TT&T 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 TT&T in future plan. The international gateway for TTT Global net also implemented by NGN.
