The document discusses the interworking strategy and parameters for multicarrier networks in Hanoi, Vietnam. It proposes two scenarios for the random camping strategy across U2100 F1, F2, and F3 carriers in the idle and connected modes. It also provides settings for inter-RAT handover between U900, U2100 and GSM networks.

3G Multicarrier Strategy for Macro
Strategy for Macro 3G cells:
I. Based on the current situation:
 Ha Noi Network already applied for Random camping to share the network resource and
capacity.
 Data traffic and DL/UL throughput are preferred to increase for better user experience
 The distribution of F3 Carrier in whole 9 Ha Noi RNCs
We suggest Random camping strategy in Ha Noi as 2 scenarios below:
Scenarios 1: For RNC more than 80% number of cells already have F3 (1109, 1110, 1112,
1113)
1. Idle mode: UE will camp on F1, F2, F3 randomly.
2. Dedicated mode:
 F1 carrier: R99 + HSPA
 F2 Carrier: R99 + HSPA
 F3 Carrier: R99 + HSPA

7. HUAWEI TECHNOLOGIES CO., LTD. Page 7
Based on Carrier Distribution, we can see that 5 RNC has number of F3 cells less than 80% (1111, 1114, 1115, 1116,
1117), we suggest to Let F3 share the data mostly and idle mode only camping on F1 and F2 due to continuous
coverage. This can provide more data resource for network.
Scenarios 2: For RNC less than 80% number of cells already have F3:
1. Idle mode: UE will camp on F1 and F2 randomly.
2. Dedicated mode:
 F1 carrier: R99 + HSPA
 F2 Carrier: R99 + HSPA
 F3 Carrier: HSPA (before: F3 carrier for R99 + HSPA)
