“one more question : if a BCCH in the SI2 is the same as the BCCH of a vPLMN cell, can the cell mistakenly reselect the other vPLMN neighbor cell ? I would say “no”.. but i’m not sure. Any idea ?”
I think, that BSIC (BCC and NCC) must be used for avoiding this problem. As it is said in 03.002:”…care should be taken to ensure that the same NCC is not used in adjacent PLMNs which may use the same BCCH carrier frequencies in neighbouring areas”
