Parameter
Description
Range
Ericsson Dafault Value
Remarks
LOL
Pathloss threshold.
0 to 200

Pathloss threshold. It defines the OL subcell coverage border in terms of the pathloss from the serving cell.
LOLHYST
0 to 63

Hysteresis for the pathloss criterion during evaluations for the OL subcell coverage.
DTCB:

-63 to 63
-63
Distance to cell border threshold. It defines the OL subcell coverage border in terms of the signal strength difference between the active channel and the strongest neighbouring BCCHs.
DTCBHYST

0 to 63

Hysteresis for the DTCB criterion during evaluations for the OL subcell coverage.
NDIST

0 to 63

Distance to cell border additional threshold.
NNCELLS

1 to 5

Number of strongest neighbouring BCCHs for the DTCB criterion. See the comments for NDIST.
TAOL

0 to 61 Bit periods (bp)

Timing advance threshold. It defines the OL subcell timing advance border
TAOLHYST

0 to 61 Bit periods (bp)

Hysteresis for the timing advance criterion during evaluations for the OL subcell coverage.
