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

HSDPA - HSUPA performance

HSPA+ introduction

HSPA+ enhancements

Advanced HSPA+ features

IP interface addressing Packet data traffic

HSPA accelerating data adoptionHSPA+ aligned with full HSPA+ ecosystem ramp up

Step by Step approach :Smooth E2E evolution towards full IP of transport architecture

Step by Step approach :Smooth E2E evolution towards full IP of transport architecture

Full IP transport

IP interfaces customization & optimization

CS Voice over HSPA+ as a first step.

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

CAPEX & OPEX savings: IP/Ethernet cost efficiency IP-based UTRAN cost is much less than ATM-based UTRANPseudo-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


3China Unicom: 3G HSPA deployment


China’s telecom market overview

8%

China MobileChina UnicomChina Telecom

Mobile business market share Fixed business market share

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 (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)


Thank you for your attention
