I am trying to understand the handover proceedure in GSM. I read the standard GSM 0508 but I got confused.
In the BSS pre-processing section it is said, that handover reasons might be that x out of y values are below a threshold (e.g. RXLEV, PBGT).
However, in the BSS decision algorithm there are other minimum levels for RXLEV and power budgets are taken into account.
Does “BSS decision algorithm” mean that this algorithm just selects and ranks the possible target cells but the handover reason is given by the threshold comparisons?
