Mobile telecom market trend
Data revenues per user increase
Data revenues per Mbit decrease
-> Cost per Mbit MUST decreases

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

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)
