  1. Integrated Management for the Next Generation Network Ilsoo Ahn NMS R&D Lab Samsung Electronics Co., LTD. Samsung Confidential

  2. Outline • Next Generation Network • Next Generation OSS • Integrated Management

  3. Next Generation Network Intelligent Network • Convergence • Voice, data, video : multi-media services • Narrowband and broadband • Wireline and wireless • Local and long distance • SoftSwitch technology • Packet transport network : IP and ATM • Intelligent Network : Service Creation / Control • Open systems • Commercial-off-the-shelf technology SoftSwitch Access Gateway Packet Network (IP/ATM) Wireline Internet Wireless

  4. DB PSTN Network Architecture SS7 Network SMS Billing Server OSS Network Management Center SCE STP Application Server Service Management RADIUS Server Media Server SIP INAP SIP Proxy/Redirect Server MGCP SIP GateKeeper H.323 Element Management System SIP-T Softswitch Softswitch Enterprise Network MGCP/ Megaco MGCP/ Megaco PACKET Network (ATM/IP) AGW TGW Access Network POTS xDSL Leased Line TGW WMG PBX SIP Phone H.323 Phone Enterprise Network RGW MSC/BSC IP phones Mobile Network PSTN/ISDN

  5. Intelligent Network Wireless Internet PSTN SoftSwitch SoftSwitch • Control call connection for MG • MGCP,MEGACO/H.248 • Multimedia services • voice, data, video • PSTN and packet signaling • SS7, SIP • Open Interfaces • PSTN, MGW, Application Server Softswitch Application Server Packet Network (IP/ATM)

  6. PSTN IP/ATM Access Gateway (AGW) Access Gateway • Interface to a packet transport network • as well as existing PSTN • using V5.2 or GR303 various user access interfaces : • POTS • xDSL Interface • Leased Line ( ATM, FR, TDM ) • PBX Trunk Group • ISDN Interface (PRI, BRI) Softswitch MGCP,MEGACO/H.248 V5.2 POTS/PBX ISDN xDSL Leased Line Access G/W

  7. OSS Generations Generations 1 G 2 G ( 3 G ) International Standards IETF SNMP ITU-T TMN (1988) TMF NGOSS ITU-T M.3020 (2000.02) Proprietary Interface Protocols ASCII X.25 TCP/IP SNMP CMIP SNMP CMIP CORBA IIOP Characteristics Software Technology ad-hoc SNMP / TMN Toolkits Object-Oriented COTS SW User Interface Character-based, Graphical X Windows Visual C++ Java Web XML

  8. Next Generation OSS for NGN • TMN in transition : M.3020 (2000.02) • TMN Interface Specification Methodology Requirements Analysis Design Implementation Protocol Neutral Information Spec. Protocol Specific Information Spec. Test Spec. Business Spec. UML Use Case Diagram UML Use Case Diagram State Diagram Activity Diagram Class Diagram GDMO CMIP IDL IIOP (CORBA) Translation SNMP

  9. … • OSS through Java Initiative (OSS/J) • open, standard set of JavaTM API’s • OSS Common, Service Activation, Quality of Service, Trouble Ticket, Billing, Inventory API’s • TMF : NGOSSTM • New Generation Operations Systems & Software • Based on contract specifications and shared information • OSS integration with components supporting contracts • Common communication infrastructure : messaging bus • Commercial-Off-The-Shelf Software : plug & play • A lot of progress, but still lacking theStandard • Too many, too little, too late : burden on the industry

  10. Integrated Management • Scope : TMF e-TOM (Telecom Operations Map) • Horizontal integration : end to end • Customer Operations Processes : Fulfilment, Assurance, Billing • Multiple network elements : SoftSwitches, Access GW, Trunking GW, Wireless GW, Home GW, Application Servers … • Multiple technologies : Voice & data, Circuit & packet … • New applications/services • Next Gen. Wireless Service : 2.5G, 3G (CDMA-2000, W-CDMA) • Mobile Internet, Wireless LAN • Broadband internet access : xDSL, Cable Modem, FTTx • Location based services, Multi-media applications • Multiple protocols : TL-1, CMIP, SNMP, CORBA, XML …

  11. … • Vertical integration : top to bottom • Business management : CRM, Supplier/Partner RM, Billing • Service management and Operations : QoS, SLA • Resource Management and Operations • Correlation of network events to customer impacts • Management of user terminals • Home Networking with intelligent gateways • Mobile devices : PDA’s, Handsets … • Remote Management • Fault Diagnostics / Localization, Loop Management • Auto Configuration, Remote Download • Efficiency : technical as well as economical • Financial constraint on the Telecom industry • Commercial-off-the-shelf rather than custom solutions

  12. Implementation • One large system does it all ? • A set of loosely coupled distributed systems • Integrated EMS for muntiple NE’s : SoftSwitch, Access Gateway, Application Servers … • Integrated systems for each management functions : Fault, QoS, Provisioning, Inventory, … • Common platform • Common internal architecture : client/server • Common look & feel : Java & Web-based, user-friendly GUI • Mediation for multiple protocols : CMIP, SNMP, TL-1 … • Multiple external interfaces : CORBA, TCP/IP, XML (preferred) • Support for legacy network and systems • Flexible customizations on user requirements
