  1. Mobile Soft Switch-Bridging Now and Future Moheb A. Ramses Technical Director, Mobile Networks MENA Region

  2. Overview of MENA 2G Market Source: EMC World Cellular Database, Dec 2004 In 2004, MENA is the fastest growing wireless market . In the next 3 years, 2G subs will keep on fast increase…

  3. 3G, a new engine of ARPU improvement UMTS subscribers number hits 16 million worldwide by the end of 2004, an increase of464%on the figure for the end of 2003. In Middle East & North Africa Region: 2 commercial UMTS network, 7+ trial & pilot UMTS network.

  4. What are the Opportunities and Challenges? 2G Expansion 3G Services Launch Current Network • How to balance 2G Network Expansion& New 3G Service Launch? • How to deploy UMTS step by step ?

  5. Mobile Soft Switch is Bridging Now & Future Flexible, Distributed Networking IP/ATM Bearer Network Save CAPEX Rich Services and Quick Response Save OPEX Centralized O&M Smoothly evolve to IMS

  6. Mobile Soft Switch, for 2G/3G convergence BSC Abis BTS Unified Core network both CS and PS PCU GSM BSS RNC Iub Node B UMTS RAN • Future-oriented Network Architecture • 2G expansion and new 3G services deployment simultaneously

  7. Mobile Soft Switch benefits(1): Distributed networking PSTN PSTN PSTN PSTN Traditional network Large city MSC Small city BSC BSC • Reduce CAPEX & OPEX • Improve Network Quality • Save Long Distance Transmission Soft Switch network Large city Small city MGW MGW MSC Server BSC BSC

  8. Mobile Soft Switch benefits(2): Supporting VoIP MSC Server 2 MSC Server 1 IP Backbone MGW MGW MGW MGW MGW Local PLMN Local PLMN Local PLMN Local PLMN Local PLMN • Save transmission and make O&M simple, reduce OPEX! • Trfo/TFO can improve voice quality and reduce CAPEX! Assume that 75% call is mobile to mobile call, the TC resource of MGW will be reduced to ¼ of traditional network which is the most expensive part of MSC • Support VoIP with G.711/ G.729 / G.723 / AMR codec. • Support VAD and TFO/TrFO technology. At least save 50% transmission resource

  9. Mobile Soft Switch benefits(3): Easy service deployment, Service convergence and More revenues Service & Application MSC Server TDM/IP Bear MGW MGW MGW MGW MGW MGW MGW Soft Switch network Traditional network To introduce new service ,only related to MSC server, simple task for me! To introduce new service, all MSCs have to be upgraded. A torturous and erroneous task!

  10. Mobile Soft Switch benefits(4): Centralized O&M IN AppServer NMS Route/PolicyService MSCServer O & MCenter MSC Server SG ISUP LocalNetwork B LocalNetworkA MGW MGW MGW MGW switch MGW MGW MGW PSTN STP The manpower can be reduced to 1/3 of traditional network, reduce OPEX! • Main task for CN O&M is signaling tracing and analyzing • Service and signal control are concentrated on MSC Server • Easy for network maintenance and management, and improves the reliability of network.

  11. Mobile Soft Switch benefits(5): Evolve to IMS smoothly SIP AS CS network IMS network HSS MSC serer MGCF HLR CSCF H.248 H.248 MRF IM-MGW MGW 2G/3G RAN Legacy network 2G/3G RAN Other netork • Softswitch based CS can be smoothly evolved to IMS: • MSC server evolved to MGCF • MGW evolved to IM-MGW

  12. IP bearer network, a key factor for Soft Switch Success • MPLS + Network Planning • Dual Plane Network • Failure Detection • Fast Routing • … • QoS • Network Security • Reliability As a leading IP Technologies supplier, Huawei has solid experience and completely IPTN solution, to meet this requirement. IP Telecom Network = IP technologies + Telecom Operation Requirements
