IP

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
BENEFITS
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 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
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)
