3. Conduct Second Query on the Worst Cells to find Reasons for RRC Rejection.

Locating Problems:
The RRC rejection isdue to powercongestion.

4. Solution
The reasons for RRC setup rejection due to resource congestion.
RRC_REJ_POWER_CONG_CELL:
In this case, the RRC setup rejection is due to thepower congestion. It is means the configuration of CAC parameters should be considered
whether it is reasonable, if this indicator is always high, it is means that the cell load
reaches the threshold. The network needs expansion or balancing the load.

1. Right-click on the RNC Daily Report and choose the Execute option.
2. Set the date in the Generate Performance Report dialog box.To generate the daily report, the begin date should be as same as the end date.

3. Focus the mains reasons of CS call drop on the Top10 worst cells.

4. Solution
In this case, we can find the main reason of CS call drop is due to UL synchronization
failure. It should be cause by some problem of coverage or neighbour list missing or
abnormal handover parameters, we recommends to check these.
If the problem still exist after check all parameters, the next step is analyze the
engineering parameters to improve the coverage, for example, adjust the down tilt and
33333333www.huawei.comHuawei confidential, 2007-06
azimuth of the antenna.
If the adjustment in antenna cannot remove the coverage hole, we recommend to add
more sites or repeaters.

5. After the optimization, generate the RNC Weekly Report to check the KPI performance.

A ter t e optimization onthe worst cells, the call
access rate in the CS orPS domain increases andcall drop rate decreases.
