In a method and an apparatus for indicating problems data from, typically automatically, entered cell relations is compared to site location information and mobile measurements, if available. An indication of a possible problem is triggered if the comparison indicates that the cell added as neighbors are not suitable as defined by one or many threshold functions. In accordance with one embodiment method of problem indication generation in a cellular radio system is provided. An apparatus receives a neighbor cell relation entries and site location information. The received information is compared and a problem indication is generated if the comparison indicates that cells entered neighbor cells are not close to each other as defined by at least one threshold values.
