Reply To: What is BSIC?


Hi Dimapl,

What do you mean in the “Does it imply that core-MSC changes at the inter-PLMN handover?” phrase? Sorry for my stupid English!

I think when the MS moves from its HPLMN to another PLMN, the roaming subscription check must be performed first. Hence the MS cannot maintain the call in progress. In other words, the “inter-PLMN handover” terminology does not exist.

Is this right? Plz give your opinion.

By the way, could you tell me what GSM specs about Roaming procedure.
