i thought it was a problem between two cells of different BSC. If both cells belong to same BSC, then …??? I’ve no idea… I would lean to a BTS hardware problem, or a BSC database definition.
If the HO CD is correct, then you could delete and re-create the relationship in the OMCR, or even delete & re-create both cells (and BTS) to clean up the database.
Does it happen with all the MS’s, all the time ?
