Abstract
A network node (600), a wireless device (602) and methods therein, for enabling access to a radio network. System signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area. The system signatures are reused in a second area as associated with system information configurations which are different than in the first area. The network node (600) indicates (6:3) that at least one system information configuration stored in the wireless device (602) is invalid and should not be used. The wireless device (602) then makes (6:4) the at least one invalid system information configuration unusable in the wireless device, e.g. by deleting it from the wireless device (602). Thereby, the risk of using an incorrect system information configuration based on a reused system signature can be reduced or eliminated.
