hi,
does enabling the ciphering in a network affect the DCR in any ways? In our network, it has been observed that after ciphering was enabled in certain BSCs, there was improvement in the DCR.
Ciphering doesn’t improve resistance to interferance, so there shouldn’t be a correlation between ciphering and DCR.
The only possible explanation is at BSC Border : it is usually difficult (depends on vendor software) to perform a HO between cells using different ciphering algo.
A cell in BSC 1 (with A5/1) might not perform HO to a cell in BSC 2 (with A5/0), therefore, without HO, there will eventually be a drop.
dear pix,
we are using alcatel BSS. can this scenario arise in alcatel?
i guess so… it used to happen few years ago (b8), perhaps now it’s working ?
