Do not apply network changes (BSIC/BCCH) while

recording.

Have a good BCCH/BSIC plan.

Maintain network data integrity BSC/Site/Cell

101

Phenomena

BCCH co-channelling exists between twoneighboring cells.

The mobile cannot identify the BSIC, and cannot

lock onto the serving sector.

Outcome

There is no measured interference among

shadowed sectors.

What is the Quality Evaluator?

The QE is an advanced semi-dynamic simulator, based

on the statistical Monte-Carlo approach.

The QE module performs an in-depth analysis of GSM network

quality.

The QE supports the following relations:

per-sectorsub-cell

channel group

any other user-defined evaluation set

Analysis is performed before results are implemented.

What is compared?

The QE predicts network quality in terms of C/I, FER, and

which give the RxQual distribution in a range of 0 to 7.
