Source: www.3gtoday.com Dec-08  Today, there are 108 commercial WCDMA operators in 47 countries. The majority are enabling HSDPA in their networks as the new baseline for 3G globally (www.gsacom.com )  Green field UMTS networks are still facing relatively high price terminals  GSM operators in MENA launch UMTS networks focusing on data services for high end users, despite the poor take-up of their 2.5G data services  There is generally a limited amount of money available from users to increase the total revenues of operators  HSDPA availability is currently boosting the 3G deployment, allowing a net differentiation between 2.5 and 3G services.  HSDPA gathers momentum in the MENA, especially in the Gulf countries like UAE, Kuwait, Bahrain, Oman, etc … HUAWEI TECHNOLOGIES CO., LTD.

Page 9 Optimized Migration Plan Shared Core Networks save CAPEX, OPEX and Improve Quality As a considerable step towards 3G deployment, we recommend GSM operators to adopt R4 Soft-switch architecture whenever they are: • Deploying a new GSM network for a new license • Expanding the core network for an existing GSM network • Swapping legacy GSM MSC Huawei Mobile Soft Switch and Packet CN achieve 2G/3G Convergence HUAWEI TECHNOLOGIES CO., LTD.

Page 17 Conclusion  The trend of telecom industry is evolving from Network Based to Customer and Services Based.  Despite the competition between UMTS and CDMA2000 as the two favorite 3G technologies, they do share a lot of similarities in their Capabilities and Roadmaps.   Shared Core Networks for 2G and 3G – whether Circuit core based on R4 softswitch or Packet core - is a major step towards a smooth migration, optimizing CAPEX and OPEX as well as improving QoS. A set of new advanced technologies in the 3G Node B’s considerably help the operators to reduce the TCO while improving the overall performance.  Hybrid TDM/IP transmission is currently the favorite solution to balance the high speed data transmission requirements and the cost of transmission resources.  Huawei strongly encourages operators to differentiate their 3G capabilities with innovative and attractive applications (especially with HSDPA mature availability), and to cooperate with handsets suppliers for affordable and customized user terminals.  Huawei has achieved a remarkable global presence and leadership in the mobile industry, witnessed by the wide global applications of Huawei GSM/GPRS/EDGE/UMTS/CDMA2000 1x/DO networks.
