2 Agenda. Customer Expectations and Industry Trends From stovepipes to layers - NGN IMS Challenges to manage the NGN IMS infrastructures The role of standards in management Processes, data, systems & networks: areas for improvement in Next Gen OSS Conclusion Next Generation Service & Systems Management 2

3 Customer expectation towards the industry. Challenges that must be addressed in NGN IMS production. Telco customer needs and challenges to Telcos Telco challenge Simplified processes Perfect Customer Care: My every day Telco usage should be more simplified with contract signing, provisioning and usage! Reduction of effort for the customer: I look for a provider that is not complicated! Telco challenge Simplified processes Telco challenge Technological transformation in net infrastructure Innovation Driver: I look for a provider that safely and dynamically accompanies me towards the future and offers me innovation and direction! Service: Competency and Service in all areas must be guaranteed. Telco challenge Improvement in process and data Telco challenge Improvement in process, data and systems Quality: I want a future-proof, comfortable and simple fullservice for a fair price and no lock-in! Reliability : I look for a reliable provider, which is a good choice in all areas! Telco challenge Optimization of network infrastructure Source: DTAG internal study, April

4 Context of migration towards Next Generation Networks. Industry transformation induces the need for a new and highly competitive production environment. Drivers Market Changes Extensively growing competition Price decline New attackers esp. aggressive IP players Internet goes wireless Customer Expectation Changes Need to attract upmarket customers Ease-of-use increasingly relevant Higher customer service requirements Requirements Significant reduction of production costs Improve production performance and customer service levels Product Changes Convergence (Fixed/Mobile & ICT) Access- and device-agnostic broadband multimedia services Product life cycles getting shorter and shorter Increase flexibility (innovation rate, time-tomarket of new products/ services) 4

6 Telco Enterprise Network Architectures. The overall network architecture will move from stovepipes to a unified production. From stovepipes per service to an open standardized layered architecture Central Functions Central Functions Fixed Access Services Services Services Control Control Control OSS Transport Transport Transport Aggregation Aggregation Aggregation Wireless Access Service Delivery Platform Service Delivery Platform Application Plane Control Plane (IMS) Fixed Transport Plane Aggregation Plane Access Plane Service Delivery Platform Wireless Next Generation OSS Technology Architecture Integration Services Circuit-switched Copper GSM/UMTS Vertical stovepipes /silos Duplicated elements per silo Multiple production platforms Network centered around voice services Packet-switched (IP- and Ethernet-based) Optical 1) OFDM 2) Horizontal layers Simplified common network architecture with fewer elements Shared production elements Network supporting broad set of applications Common service capabilities for fast product development 1) Optical and copper in last mile 2) OFDM = Orthogonal Frequency Division Multiplexing 6

11 Next Generation Service and System Management. One logical platform architecture for the management of NGN reduces complexity while improving efficiency. OSS landscape Industry trends NG OSS - Benefits Isolated local OSS: One logical platform architecture: Reduced complexity: One logical platform Common Integration & Process Automation architecture following Common Data Management standards and best practice Realized savings: Fulfillment Assurance Mediation Reduced number of OSS and optimized process PSTN ATM/ IP TDM Improved flexibility IDN+ FR OSS OSS and optimized process OSS OSS Element Abstraction speed: Modular NG SDH / PDH - OSS Advanced IT technologies are OSS architecture increasingly used in the telco world overarching all planes State-of-the-art solutions are service Customer interaction WDM - OSS oriented, enabling integration and enabling: Customer flexibility self service portals Historical grown structure Federated data usage (inventories) and Seamless services are Many one-to-one interfaces an automated process design following supported: Cross- No open architecture business needs domain view through Missing standardization NG OSS functions Voice OSS Video OSS Leased Line OSS Circuit Data OSS Switched Data OSS Managed IP OSS Internet OSS 11

13 The role of standards. Finally, OSS standards and frameworks, especially etom and ITIL, provide great value for open, modular NG OSS architectures. Standardization and framework input NG OSS coverage of etom etom NGOSS ITIL NG OSS Functional Architecture 3GPP TISPAN MTNM IPNM Main input sources to the Next Gen OSS architecture development Customized / adapted areas of the process areas of etom (e.g. as highlighted above) could be the bases for a Next Gen OSS functional architecture.

16 Next Gen OSS: Separation of process, systems, common data and network increases flexibility. Data Areas for im provement in classical Telco environments Improvements with NG OSS Process Decoupling of products and production Product oriented processes; no need for process design process definition per product Reduced manual effort in implementation End to end of processes higher degree of automization automation of processes automization System Historically grown large number of systems Tax to integrate technologies and services in existing OSS landscape Homogeneous system landscape with reduced number of systems Full flexibility for extension of modules and functions Degree of flexibilityin in scaling existing systems Full scaling flexibility Data quality and Common Data Management enables master data management flexible data re-use Flexible management of data Data exchange is enabled over standardizes interfaces Networkinfrastructure Static Quality of Service Comprehensive Services with varying degrees of QoS are possible Convergence of networks and network technologies Converged mass-market services are enabled 16

18 The NGN architecture with a domain view on Next Gen OSS. A Next Generation Service and System Management (NGSSM) approach should support all Telco Services.

19 Conclusion. If the industry manages the OSS challenges, the current production requirements can be addressed in the IMS-based NGN. Requirements Improvements in production platforms Significant reduction of production costs More efficient operations with a higher degree of automation More efficient usage of network resources Reduction of network complexity and diversity Improve production performance and customer service levels Simplified and faster provisioning of services to customers Better service management with higher degree of automation reduction of lead time to repair QoS levels equal or higher than today Increase flexibility (innovation rate, time-tomarket of new products/ services) Improved seamlessness Services are access-agnostic through IP network abstraction Flexible deployment of new IP-based services with reduced time-tomarket Enabling of future converged services 19
