HSPA+ enhancements
Advanced HSPA+ features
HSPA accelerating data adoption
HSPA+ aligned with full HSPA+
ecosystem ramp up
HSPA+ introduction
IP transport
IP interface addressing Packet data traffic
IP interfaces customization & optimization
Step by Step approach :
Smooth E2E evolution towards
full IP of transport architecture
Full IP transport
Voice over
HSPA
CS Voice over HSPA+ as a first step.
VoIP over HSPA+ and LTE will be deployed in a convergence step

15. 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

17. China’s telecom market overview

18. China Unicom: 3rd largest mobile operator in the world
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

19. 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)
