Random Strategy for 3G Huawei

[gprastomo]

Hi All,

Do you have any experience about Random Camping Strategy for 3G Huawei, which can select the lowest cell load to be camped ?
This parameter will be managed by PUC, is it correct ?

Usually when we have more than 2 carriers or 3 carriers, we will make HSPA Layer, F1 for R99 and F2 for HSPA etc with DRD/DRRC.

Now we want to implement the random strategy so the load will be balanced.

Is there any of you has this kind of strategy or document , kindly share it here, coz we plan to implement this strategy soon, we has 2 carriers and some of the cells will be 3 carriers.

if your ran is 11 i have hedex library explaining the algorithm & the related parameters .

[gprastomo]

Yes i have RAN11 and i have hedex for ran 12,

Can you please write the related parameters ?
or if you have the materials are welcomed

This is parameter and script to change strategy

1.Set service preferred parameter
MOD USPG: SpgId=1, PriorityServiceForR99RT=1, PriorityServiceForR99NRT=1, PriorityServiceForHSDPA=2, PriorityServiceForHSUPA=2;
ADD USPG: SpgId=2, PriorityServiceForR99RT=2, PriorityServiceForR99NRT=2, PriorityServiceForHSDPA=1, PriorityServiceForHSUPA=1;
MOD UCELLSETUP: CellId=xxxxx(F1 Cell),SpgId=1;
MOD UCELLSETUP: CellId=xxxxx(F2 Cell),SpgId=2;

2.Set Blind HO from F2 to F1

3.LDR Configuration

4. Active HSDPA Cell in F1
ADD UCELLHSDPA: CellId=xxxxx, AllocCodeMode=Manual, HsPdschCodeNum=5, HsScchCodeNum=3;
ACT UCELLHSDPA: CellId=xxxxx;

This one for HSPA Layering for specific carriers right ?

We need to activate the User priority control and the HSDPA interfreq handover will be based on load for random camping.
