Abstract
Embodiments provide a method, apparatus and computer program for operating a user equipment (UE). The method begins by determining that a valid authentication for the UE, generated with a radio network operating with a first radio access technology (RAT), is not a mutual authentication between the UE and the network operating with the first RAT. In response, the UE unilaterally takes action to prevent the valid authentication that is not a mutual authentication from being used to authenticate with a radio network operating with a second RAT that utilizes mutual authentication.
