� Follow Current Configuration
Basis: For some parameters wherein we find direct equivalent with the existing parameter algorithm, we follow the Current Configuration to adopt the optimization achievement of the network and maintain the same network performance.
� Follow HW Baseline
Basis: Due to the fact that different vendors have some differences in developing their individual technologies, some algorithms are basically dissimilar. This leads to some unrelated or even distinctive parameters. HW opt to use the recommended values for such parameters.
� According to the special requirement from GP
--- For discussion with GP if there are special cases to apply this method.
� Design the data according to the project progress
For example: External cells list.

May allocate TCH at Imm. Assign. if SDCCH is busy.
If existing has UL and OL subcells with same BCCH, cell is Concentric.
Extended Range means Cell can carry traffic for TA>63 or more than ~35km. In theory, distance can
be upto ~120km.
Follow existing to avoid effect on the coverage of some subscribers.
Initially we follow current. But in Huawei system, we can further optimize the function separately for TCH/F
and TCH/H.
Network Assisted Cell Change (NACC). Existing set this at BSC level while Huawei sets it at cell level.
If there is 1 or more BPC/TS configured for EGPRS, then Edge is supported in the cell.

• Location update period of MSC: The current value of this parameter is 330 min. (5.5 hrs). We suggest to set this
value to 150 min (2.5 hours) and T3212 follows to 120 min in BSC (2 hours) to improve paging success rate.
• Encryption model: A5/0 will not be supportedt? Need to confirm by GP.
• Paging Strategy: After swap we can suggest GP to use the third paging.
