Generation of Radio Measurement (MR) based Interference Matrix

[dannthemann]

Hi all,

I am working with Huawei GSM technology and I am trying to generate interference matrix to be imported into Atoll (*.im1 format).

I have been studying and I have collected the following counters from U2000:

S3013:MRs of Serving Cells
S360:Strength of Signals in Neighbor Cells
S361:MRs of Neighbor Cells
AS360:Mean Strength of Signals in Neighbor Cells
S362:Strength of Signals in Serving Cells
S363:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Smaller Than the Neighbor Cell Interference Level Threshold 1
S364:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 1
S365:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 2
S366:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 3
S367:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 4
S368:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 5
S369:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 6
S370:Number of MRs in Which the Signal Strength Difference Between the Serving Cell and the Neighbor Cell Is Greater Than the Neighbor Cell Interference Level Threshold 7

My interference matrix structure for Atoll (*.im1) is as follows, but I don't know yet how to calculate the C/I threshold and the Probability_C/I_>_Threshold colums from the counters listed above:

Interfered_transmitter	Interfering_transmitter	Interfered_TRX_type	C/I_threshold	Probability_C/I_>_Threshold
Source_1	Target_1	BCCH,TCH
Source_1	Target_2	BCCH,TCH
Source_1	Target_3	BCCH,TCH
Source_1	Target_4	BCCH,TCH
Source_2	Target_1	BCCH,TCH
Source_2	Target_2	BCCH,TCH
Source_2	Target_3	BCCH,TCH
Source_2	Target_4	BCCH,TCH

Any idea?

Thanks & best regards.
