Slide 2 PTCL Training & Development1 NGN Architecture/Layer description and NGN Trends Slide 3 NGN Architecture Characteristics of Next Generation Network: NGN is designed with an open network framework. NGN adopts the hierarchical architecture, which is divided into media access layer, transport layer, control layer and service/application layer. NGN is based on standard protocols and packet switching network. 2 Slide 4 NGN Hierarchical Architecture 3 Edge Access Core Switch Network Control Service Management Service/Application Layer Control Layer Transport Layer Media Access Layer Slide 5 Access Layer Interworks between Core Packet Transport layer and various existing communication networks. Provides access of various communication terminals such as analog phone, SIP Phone, PC Phone visual terminal and intelligent terminals to the Core Packet Transport layer via various access gateways 4 Slide 6 Core Transport Layer The packet switching network composed of backbone transmission equipments such as IP router or broadband ATM switch as the bearer basis of the softswitch system. 5 Slide 7 NGN Control Layer The control Layer combines the equipment that manages signaling and call control progress. The control handles the call setup and controls the media gateways. Major components at this layer are the soft-switches. 6 Slide 8 Application Layer Layer with various applications and services such as client oriented integrated intelligent services and service customization. 7 Slide 9 8 Service Management Network Control Core Switching Edge Access IADAMG BroadBand Access UMG PLMN/3G SGTMG PSTN UMG Packet Core Network Soft Switch iOSS Policy Server Application Server SCP Location Server RADIUS Server MRS iOSS: Intelligent network management system, SCP: Service Control Point, MRS: Media Resource Server, IAD: Integrate Access Device, AMG: Access Media Gateway, TMG: Trunk Media Gateway, UMG: Universal Media Gateway, RADIUS: Remote Authentication Dial-In-User Services NGN Network Architecture Slide 10 9 Service Layer Control Layer Core Switch Layer Access Layer SoftX3000 3G Access AMG5000 IAD Broadband Access PSTN UMG8900 SG7000 PLMN SoftX3000 IP Core Video GW UMG8900 SIP/H.323 Phone U-Path ENIP Policy Server MRS6100 IN OSS iManagerN2000 LocationServer PSTN switch STP Open Eye 2G Terminal 3G Terminal Huawei U-SYS Network Architecture Slide 11 10 SG MSAG NAS H323 GW IADWAG Access IP PBX ZXSS10 IAD Series Broadband Access PSTN/ISDN Wireless SS7 Network IP Router/ATM switch Core Packet Network Core Transport Softswitch Control ZXSS10 SS1 Router ServerSCP AAA Server Application Server Policy Server Service ZXUP10 APP AG ZXSS10 A200 TG ZXSS10 M100 ZXSS10 S100 NAS: Network Access Server WAG: Wireless Access Gateway MSAG: Multi Service Access Gateway AG: Access Gateway ZTE NGN Architecture Slide 12 PSTN Access 11 TGSG PSTN IP Core SoftswitchAPPNMS APP: APP Server: Application Server, TG: Trunk gateway SG: Signaling Gateway, NMS: Network Management system Slide 13 12 Control Stream Media Stream IP Connection TDM Bearer Network TG IP Bearer Network SG TG CityA PSTN CityB PSTN LS MS LSTP TS LS TS MS LSTP HSTP SG SIP-T TDM Connection Softswitch Control Device Signaling gateway FE/GE Signalling Gateway FE/GE TS: Tandem Switch, HSTP: High Speed Transfer Protocol, TG: Trunk Gateway, MS: Main Switching centre LS: Local Switch, SIP-T: Session Initiation Protocol for Telephone, FE/GE: Fast Ethernet Giga Ethernet PSTN-IP Toll Traffic Splitting Solution Slide 14 13 Metro Optical Backhaul Resource Manager POTS Multi Service Edge Route LAN AP IAD Softphone POTS FMC MSAN Internet SIP Phone XDSL/LAN/POTS Residential Enterprise Mobile Scenario PSTN Media GW SS7/TDM SS7/V5.2/TDM NMS ENIP Softswitch APP Server3rd Party Resource Manager Signaling GW Multi Service Edge Route User Profile Center IP Core Network IPTV SipPhone AP Convergence Intelligence Broadband ENIP: Enhanced Network Intelligent Platform, NMS: Network Management system, AP: Access Point MSAN: Multi Service Access Node, FMC: Fixed Mobile Convergence, MG: Media Gateway Next Generation Network -Future Slide 15 14 Metro Optical Backhaul POTS LAN AP IAD Softphone POTS FMC MSAN Internet SIP Phone XDSL/LAN/POTS Enterprise NMS ENIP Softswitch User Profile Center IPTV SipPhone AP IP Core Network Convergence Centralized user profile center and application layer for service convergence and fast service deployment Shared converged IP network for voice, data and mobile Unified multi-service access node for diversified services, decreasing the number of access node, Residential Convergence-oriented Slide 16 15 Metro Optical Backhaul POTS LAN AP IAD Softphone POTS FMC MSAN Internet SIP Phone XDSL/LAN/POTS Softswitch User Profile Center IPTV SipPhone AP Broadband IP Core Network Constructing high QoS network with large bandwidth Introduce various broadband access methods to support broadband service deployment Broadband NMS ENIP Residential Enterprise Broadband-oriented Slide 17 16 Metro Optical Backhaul POTS LAN AP IAD Softphone POTS MSAN Internet SIP Phone XDSL/LAN/POTS Softswitch User Profile Center IPTV SipPhone AP Broadband Intelligence Centralized user profile center, session control and application layer Bring intelligence to whole network Support fast unified service deployment NMS ENIP APP Server 3rd Party IP Core Network Residential Enterprise Intelligence-oriented
