 Optimized networks for voice and data
 Service integration requires unified network
 no difference between media (voice, data, video)
 no media dependent calls, but media independent sessions
 Easier to manage

MARKET VIEW
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.
 E2E QoS & reliability:
 Guaranteed thanks to MPLS/IP/Ethernet
BENEFITS
 CAPEX & OPEX savings:
2nd Vntelecom conference, May 9th 2009
 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

Mobile business market share
Fixed business market share
 3G in China : Three licenses
 China Mobile: TD-SCDMA
 China Telecom: Pursue CDMA2000 EV-DO path (however choose 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

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)
