  1. Analyzing the Integration of Innovative Telecommunication Technologies Project Number P-2007-055 Yossi Twizer Supervisor: Prof. Benjamin Arazi 6/6/2007

  2. Agenda • Motivations • Project Scope & Goals • Analyzed Technologies • Technologies Highlights • Preliminary Conclusions • Next Analysis Phase • Time for Questions

  3. Motivations • Interconnecting New & Legacy Telecommunication Technologies • IP based Services Convergence • Providing New services and functionalities • Core COGS Saving • Unified Access Network • Follow the $ • Big money opportunities • Market leadership

  4. Project Scope • Analyzing 4 Leading Telecommunication Technologies: • Focusing on Protocol Level • Top-to-Bottom Approach • Special Attention on Signalling & Traffic delivery flows • Current Interoperability Analysis • Gaps Detection • Analyzing the IP Convergence Impact Analysis: • Networks Architecture changes • New Signalling protocols and information flows • Integration Point Analysis

  5. Project Goals • Acquiring High Level of Understanding • Per technology • Per protocol • Mapping current gaps in existing architectures • Signalling convergence issues • Install bases and migration paths • Detecting & offering the optimal integration point

  6. Analyzed Technologies • Focusing on the following Leading Technologies: • PSTN – Public Switching Telephony Network • Cellular Networks – 2.5G & 3G GSM Networks • VoIP Telephony Services • IP Multimedia Subsystem (IMS) • 3G Core Implementation • NGN Cores Implementation • Cores for New Access technologies (WiMAX)

  7. PSTN Technology Highlights • Plain Old Telephony System (POTS) • Worldwide install base • Highly adopted & Fully integrated • Offering basic Services • Circuit Switch Based • Low efficiency Vs. High Quality • Dedicated signalling system • “Stupid” End-User Equipment Vs. Smart Core • Low level of flexibility • High cost for convergence • Emulation \ Simulation concept

  8. 2.5G & 3G GSM Networks Highlights • Public Land Mobile Network (PLMN) • Amazing install base (over 2B of users) • Offering both IP & CS services • Integrated Interoperability through PSTN • CS migration to Fully PS configuration • R7 is expected to be IPv6 with VoIP implementation • Dedicated Signalling protocols • “Smart” handsets • High level of flexibility • Handsets readiness for fully IP env. • High cost for new Core technologies

  9. VoIP Telephony systems Highlights • Voice over Internet Protocol (VoIP) • Greatest impact on telecom world • Major COGS saver at core level • Expensive at last mile level • Fully PS concept • High efficiency • QoS and regulation issues (911, 5-Nines) • Requires expensive UE • Multiple signalling protocols • Integration issue (!!) • Penetrating as part of 3Play

  10. IMS Architecture Highlights • IP Multimedia Subsystem • Totally new core technology concept • Signalling – SIP based • Traffic – over IP fully flexible • Last mile – undefined ! • Originated for 3G GSM, adopted by: • CDMA2000 (3GPP2) • NGN TISPAN • WiMAX Forum • Implements a unified core • Regardless of Last mile • Regardless of service • Offering new roaming services

  11. Preliminary Conclusions • Best integration point is at the CORE level • Saving CORE COGS • Offering new services (e.g. Fixed-Mobile Roaming) • Converging infrastructures • SIP signalling is considered Highly efficient • Supports service initiation, billing, Telephony services • Is not aware of service type – full flexibility • Easy to adopt • IP migration is expected to be highly expensive • Last mile issue • Handsets issue

  12. Preliminary Conclusions- Cont. IMS integrates it all and therefore is expected to be a leading technology bridging between future IP bases services !! • NGN Networks - Fixed • Future Cellular – Mobile • WiMAX Solutions - Wireless

  13. Next Analysis Phase • In depth analysis of IMS technology: • Detailed NGN integration concept • Detailed SIP signalling flows • Advanced capabilities analysis (e.g. Roaming) • Study cases analysis • Learning from first implementations • Detecting on-field integration problems

  14. Thank You! Time for Questions….
