Step 1 - Traffic Balance between 3G Layers

Note (The load in the same sector can be adjusted. M2000 1 min monitoring can be used to analyse the load balancing
has been triggered).
Step 2 - Reduce Pilot power to 5% of the maximum power

MOD UCELL: CellId=xxxxx, PCPICHPower=330;

Trigger when cells have been detected as bad access performance due to resource limitation. RRC Congestion
rate is more than 10% and CS blocking rate is more than 5%.

Reduce pilot power to 5% of maximum power gradually in step size of 1db.

Note (When reducing the CPICH all the cells (layers) in the sector have to be on same level for example if degradation is
observed on 209682_SurryHillsNorth_MO_U21A_3 and CPICH has to be reduced it will be done for both carriers
209682_SurryHillsNorth_MO_U21A_3 and 209682_SurryHillsNorth_MO_U21B_3.
Step 3 - Traffic Shifting From 3G-2G

Works great with GSM co-site can also be implemented on the tier 1 neighbours than other GSM neighbouring cells can
be changed according to the congestion.
Step 5 - Modify the minimum of cell access EcIo
LST UCELLSELRESEL:CELLID=XXXX; (Base line values, Min quality level = -18 and Min Rx level = -58)
MOD UCELLSELRESEL: CellId=XXXXX, QualMeas=CPICH_ECNO, Qqualmin=-14, Qrxlevmin=-52;

Note (The modification should be according to distance between SE areas to the related site, only the very near Main
SE site can be modified. Otherwise, it will impact the user experience. This parameter should only be implemented as a
last resort and extreme values can be changed to Qrxlev = -50, Qqualmin=-14.
