Veeru,
Peace of cake! all you should do is look for these parametres in your database:
RXQUALHO=TRUE
RxQual handover enabled, determines whether handover due to
bad receive quality on uplink or downlink is enabled. This flag is only relevant if intercell handover is enabled in the cell (INTERCH=TRUE,see above). Bad receive Quality is determined by error rate
measurements in the MS and the BTS. Further parameters relevant
for this type of handover are HOAVQUAL, HOLTHQUDL and
HOLTHLQUUL, HOLTHQAMRDL and HOLTHQAMRUL (see above).
Note: this flag only determines whether inter-cell handovers may be executed with cause ‘quality’.
HOLTHQUDL/UL=9
Handover lower threshold quality downlink, defines the receive
signal quality threshold on the downlink for inter-cell quality handover
decision. This parameter is only relevant if intercell handover due to quality is enabled (RXQUALHO=TRUE, see below). Starting from BR9.0, the value is no longer entered as RXQUAL value but as C/I value in dB.
QUALLEVHOM=69
Level handover margin for quality handover, this parameter
defines the handover margin for handovers due to uplink quality or
downlink quality. The quality handover is triggered if the UL or DL
receive level of the serving cell drops below of the thresholds
HOLTHQUDL (for AMR: HOLTHQAMRDL) resp. HOLTHQUUL (for
AMR: HOLTHQAMRUL) – for further details about the thresholds,
please refer to the command SET HAND [BASICS]. If the feature
‘Level handover margin for quality handover’ (see parameter
ENAQUALEVHOM in command SET HAND [BASICS]) is disabled
(ENAQUALEVHOM=FALSE), the target cell only has to fulfill the
handover minimum condition
RXLEV_NCELL(n) > RXLEVMIN(n) + Max(0,Pa).
to be included in the target cell list of the INTERCELL HANDOVER
CONDITION INDICATION with the cause values ‘uplink quality’ or
‘downlink quality’.
If the feature ‘Level handover margin for quality handover’ is enabled
(ENAQUALEVHOM=TRUE), also the absolute level difference
between the serving cell and the neighbour cell is considered. In this
case the neighbour cell only appears in the target cell list if its power
budget exceeds the entered level handover margin:
RXLEV_NCELL(n) > RXLEV_DL + QUALLEVHOM(n)
in addition to the handover minimum condition.
