Increase in Interferance HOs with DTX

[mojiiiiii]

In one cluster of our Network AMR was enabled and after enabling AMR DTX for both AMR FR and HR was enabled as soon as DTX was enabled Interference HOs increase for all cells .

Reason provided by Vendor is that after enabling DTX RXQUAL measured by Mobile Station is over only 12 TDMA frames(SID and SAACH) resulting in decreases accuracy as desacribed in 05.08 series of 3GPP Recommendation.

Vendor is Nokia, so question is for Nokia experts if they have encountered anything like this in their networks?

Beside what you got is also
When AMR is active MS can make call in bad Radio Quality ( RX qual 5 and 6) so according to emergency HO due to Quality the threshold is put for example 5 now you have to change it to 6 so that the MS donot make any emergency HO due to Quality in level of 5.
