kamal,
which MS are unreachable ?
the ones in PTM especially ?
or even the ones which are in idle mode?
the SGSN will only be in charge of paging the MS which are in PTM. In other words, the Gs interface is used only to page MS in PTM.
MS in Idle mode (PIM) are paged by the MSC directly, through the (Air) PCH.
