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

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

3 Next Generation 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 WirelineInternetWireless Packet Network (IP/ATM) SoftSwitch Access Gateway Intelligent Network

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

5 PSTNInternetWireless Intelligent Network Packet Network (IP/ATM) Application Server 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 Softswitch

6 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) Access G/W POTS/PBX ISDN xDSL Leased Line PSTN Softswitch MGCP,MEGACO/H.248 IP/ATM V5.2 Access Gateway (AGW)

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

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

9 … OSS through Java Initiative (OSS/J) open, standard set of Java TM APIs OSS Common, Service Activation, Quality of Service, Trouble Ticket, Billing, Inventory APIs TMF : NGOSS TM 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 the Standard 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 : PDAs, 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 NEs : 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
