Agenda • Market & Technology trend • Introduction of IP in 3G/LTE solution • China Unicom: 3G HSPA deployment
1 Market & Technology trend
Mobile telecom market trend • Data revenues per user increase • Data revenues per Mbit decrease -> Cost per Mbit MUST decreases

VoIP over HSPA+ and LTE will be deployed in a convergence step Utran sharing UMTS 900Mhz Utran Sharing MOCN
Benefit of IP transport migration • Few full IP network planned / in deployment • Smooth E2E evolution towards full IP of transport architecture • Stepped approach addressing first data traffic growth with IuPS over IP & Hybrid Iub • Migrate all interfaces (Iub, Iu-CS, Iur) to IP in a second step. MARKET VIEW • E2E QoS & reliability: • Guaranteed thanks to MPLS/IP/Ethernet • CAPEX & OPEX savings: • IP/Ethernet cost efficiency • IP-based UTRAN cost is much less than ATM-based UTRAN • Pseudo-wire is used to transport ATM over IP (one IP backbone) • Prepares mobile operators effectively for a future evolution to native IP in the mobile network (HSPA+, LTE solution) • Single IP network for the Transport Plane, the Control Plane, and the Operations and Maintenance Plane BENEFITS
3 China Unicom: 3G HSPA deployment
China Unicom: 3rd largest mobile operator in the world • 3G in China : Three licenses • China Mobile: TD-SCDMA • China Telecom: Pursue CDMA2000 EV-DO path (howeverchoose LTE for 4G) • China Unicom: Choose 3G WCDMA • WCDMA vendor: Alcatel-Lucent, in fact Alcatel Shanghai Bell (ASB) • WCDMA HSxPA product: last version with hybrid Iub & Iu-PS over IP • Core network: Huawei’s MSTP solution Mobile business market share Fixed business market share
How can the ALU win the contract? • Procurement: ALU (ASB), Ericsson, Huawei, ZTE • Each vendor did a trial China Unicom then made a choice • To win this contract, ALU must propose very low price (the same as the one proposed by Huawei) • Consider the gain for the long term and from the support • The following steps were taken to secure the deal ….. • Persuade customers • Lobby customers • Set reasonable price • No ASB, ALU cannot win the contract due to political issue (local vendor)
