Benefit of IP transport migration

Few full IP network planned / in deployment

Smooth E2E evolution towards full IP of transportarchitecture

Stepped approach addressing first data traffic growthwith IuPS over IP & Hybrid Iub

Migrate all interfaces (Iub, Iu-CS, Iur) to IP in a secondstep.

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 futureevolution 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

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)
