Hi,

Can anyone please share the knowledge on Huawei LDR & DCCC algorithm please?

thank you

Hi, I have found this easy to understand exemple : http://www.scribd.com/doc/68999302/E...ongestion-Case

What exactly do you want to know? have you solved your problem already?

Parent Document. Hope this works for you

RAN12 I cant make it work ! is it working for you ? can you give an example for UL_LDR or DL_LDR (I mean RX or TX power LDR triggered action counters....)
thxs!

I dont understand what u mean. U want performance counter for LDR or?

For newer versions RAN 12 and above u add a U before the command. For example:
1. MOD UCELLALGOSWITCH. In this step, turn on the following switches of Cell LDC algorithm switch:
–UL_UU_LDR: UL UU load reshuffling algorithm
–DL_UU_LDR: DL UU load reshuffling algorithm
–CELL_CODE_LDR: Code reshuffling algorithm
–CELL_CREDIT_LDR:Credit reshuffling algorithm
2. Run the MML command MOD UNODEBALGOPARA. In this step,
turn on the following switches of NodeB LDC algorithm switch:
–IUB_LDR: NodeB Iub reshuffling algorithm
–NODEB_CREDIT_LDR: NodeB-level credit reshuffling algorithm
–LCG_CREDIT_LDR: cell-group-level credit reshuffling algorithm
There you have LDR activated both on the Node B level and cell level.

ok, the activation is well described in Hedex. the thing is.... if you get your most loaded cell... can you show me in a graph at least one action that´s being done because of the congestion ??

Hello Erastus, could you please forward that information to my email angelica969@hotmail.com I am not able to download this information

Thanks a lottttttttttttttt in advance
