PS CSSR Optimization

[ASAP168]

Hi Experts,

Recently, I have problem with PS CSSR (NSN). I found the main reason, PS RRC Fail due to Admission Control.
Can you give me some ideas to improve this ?
Thanks in advanced !

Dear ASAP168 ,

this may be due to wrong power parameters in wcel series dump. you can also go through the report RAB stats.which is in capacity section.

hope it helps...

Cheers

Dear dpandey456,
3G NSN seems to be new for me. Can you just give me some parameters.
Brs,

hi friend
- In my network, the main reason of fail AC are: Congestion DL and UL Power. PLS check these paras

For reducing DL power you need to either optimize the cell boundaries (Reduced coverage) or add another sites/New carrier or new sector.
For UL power you need to increase ENU (equivalent user number)

hi friend
- can you give more info about ENU? Thanks

What are all the counter will show me the intensity of such issue ?

Hi dtvt2,

ENU is Equivalent User Number. This parameter is used in Huawei for Admission Control. It defines the equivalent user number which corresponds to 100% load (i.e it indicates the maximum number of users allowed in a cell). If this parameter value is set to too low value, the possibility of user reject will increase, resulting in waste of resources. On the contrary side, if its set to too high value, more numbers of users will be allowed admission but the chances of system congestion will increase. Its range is 1-200 but generally it is set to 80-100 for optimum performance.
