Thank you very much for your information. However, I still want to know, why the MS does not use the Cell ID instead of BSIC for the adjacent cells in the measurement report it sent to the network?
Another question about handover: As you may know, the handover procedure preserves call connection as MS move from one radio coverage area to another during a call. Do you think the MS may perform handover from cell A of its home PLMN to cell B of another PLMN (i.e. roaming and then handover without interrupting the call)?
