i know that a area in which a paging is broadcasted is not always the LAC : it depends on a NSS parameter (MSC ?)
you have to check it out because i don’t know the details : a paging can be sent to :
– all cells within a LAC
– all cells within a BSC only
– perhaps, all cells within a BSC and within a LAC of this BSC
– all cells within the MSC
the first paging is maybe on LAC, then if there is no answer, second attempt is on the full BSC, then full MSC ? that depends on parameters.
