please advise me what is better about these ALU parameters?
– EN_BI_BAND_MS(n) should be enabled or disabled.
– Ext_BCCH should be enabled or disabled for cell with Extended BCCH freq.
Thank you in advance..
en biband ms should be enabled, but it has an impact only on some “capture” causes, as far as i remember. Disabling it will generate some chaotic HO behaviour, so unless you know exactly what you want to achieve, then you should enable it by default.
ext bcch : i’m not familiar with this parameter. what is its description ?
The recommended rule is linked to the fact that when the SI2bis message is sent, it is recommended to activate the extended BCCH
i) for 2G to 2G cell reselection to reduce the cell reselection duration
ii) for 2G to 3G cell reselection to reduce the acquisition of the system information on 3G cells….
