  1. Restructuring the Telecommunication Networks First International Working Conference on Performance Modelling and Evaluation of Heterogeneous Networks (HET-NETs ‘03, 21st-23rd of July 2003) Rodolfo López Aladros, Franz-Josef Banet, Dr. Stephan Rupp, Dr. Ehrhard Winter

  2. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  3. The current problem

  4. No future! Telco Networks Today Specialised Network Elements Y.V1.3#4 Specialized Protocols S.V5.1#3 X.V2.5#17 • a closed environment • a network for each service • too complex • too expensive Z.V1.2#19 Subscriber Data enclosed in Network Elements

  5. The KILLER application in mobile networks • The killer application for the next 5 years: HUNDRED NICHE APPLICATIONS • There is plenty of room for niche applications (supposed they are easy to use): • 1 single niche application may not show up in your balance but, • 50 niche applications may boost your business.

  6. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  7. MSC Call Control Mobility Management VLR Switching Today: Control & Connectivity are combined Example: Circuit Switching MSC: Mobile Switching Centre VLR: Visitor Location Register Control Functions and Connectivity Functions in the same Network Element

  8. Control Plane Call Server Connectivity Plane MGW MGW Next Generation: Separated Control and Connectivity Example: Circuit Switching Call Handling Mobility Management VLR Media Gateway Control MGW: Media Gateway Connectivity and Transport (Switching, Routing)

  9. Business Plane SAP …. CRM CCBS O&M HLR SMS SCP …. MMS Service Plane Call Server Control Plane GGSN MGW SGSN Connectivity Plane There are some more planes CCBS: Customer Care and Billing System CRM: Customer Relationship Management O&M: Operation and Maintenance SAP: Systeme, Anwendungen, Produkte in der Datenverarbeitung

  10. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  11. Business Plane SAP Storage Plane CRM CCBS O&M SCP HLR Service Plane Call Server Control Plane MGW GGSN SGSN Connectivity Plane A new approach: NGN with consolidated storage

  12. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  13. 1 Physical Consolidation of Storage Three orthogonal directions to simplify MNO’s life

  14. Get the data out of the network elements • facilitates integration • facilitates introduction of new services • facilitates NM & OSS • simplifies NE • uses standard IT technologies Y.V1.3#4 S.V5.1#3 Z.V1.2#19 Data Interface storage

  15. Application servers (HLR, SCP, MMS, Billing, CRM, CC, …) Data network Data Servers Fibre Channel (FC) FC Switches / Directors FC SAN FC Storage system (disks & cache) Robot & Tapes Backup Server The physical implementation of the Storage Plane

  16. 2 Logical Consolidation of Storage Three orthogonal directions to simplify MNO’s life

  17. SCP HLR CRM Billing CC Marketing A conceptional switch: This way…? The Customer

  18. SCP HLR CRM Billing CC Marketing A conceptional switch: … or this way? Consolidation of customer data “The CUSTOMER PROFILE”

  19. 3 Consolidation of Interfaces Three orthogonal directions to simplify MNO’s life

  20. Application Interface CF n Ap 1 ……. Ap n CF 1 DBS DBS DBS Data Interface SAN Data Objects Two Busses instead of many Interfaces (Sandwich) for the internal implementation • Functional modules and applications • protocol binding • re-use of functions (such as AA) • easy to extend • easy to integrate • easy to maintain Ap: Application CF: Common Function DBS: Data Base Servers SAN: Storage Area Network

  21. Third party Applications Operator’s Network Application Interface App. 1 App. App. CF CF App. N Data Interface storage Extranet Intranet Use a service architecture for new applications • standard interface towards external applications • scalable • open • easy to integrate

  22. Legacy Business Applications Legacy Telecom Applications Billing Other Application Interface GGSN CF 1 Ap 1 EAI CF n DBS DBS DBS Ap n TAI Data Interface Other SCF CRM DB DB DB DB DB DB Data Objects SAN A.: Application CF: Common Function DBS: Data Base Servers SAN: Storage Area Network EAI: Enterprise Application Interface TAI: Telecommunication Application Interface

  23. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  24. WLAN PoLoS: Integrated Platform for Location Based Services Overview Service Creation Environment (Outdoor) GPS Mobile Services Geo Information System Position (Indoor) Platform Service Execution Service PoLoS Consortium Proprietary

  25. Service Creation Environment GPS Java WLAN UMTS Interfaces GIS Component Component GSM/GPRS HTTP Text Data WAP Graph Data SMS Harmonizing the Application Interface by using Web Services technology PoLoS platform Web Services based interface PoLoS Kernel Positioning Component OSA Network Infrastructure PoLoS Consortium Proprietary

  26. Agenda • Some problems Mobile Network Operators are facing • The tortuous way of network restructuring • Giving Data the role they deserve • Three orthogonal directions to simplify MNO’s life • EU project PoLoS: applying theory in the praxis • Conclusions

  27. Conclusions 1 Current mobile networks are very complex This complexity increases with each new application “HUNDRED NICHE APPLICATIONS!” Integration and maintenance costs increases

  28. Conclusions 2 To reverse this evolution, out-of-the-box thinking is required A switch from a functional centered architecture to a data centered one: the storage plane Current infrastructure (i.e. SAN) and software tools (Object Oriented approach, CORBA, Database servers) supports the consolidation of data Consolidate the interfaces : decrease work-flows complexity and integration effort
