Abstract
Methods, devices, computer programs and carriers comprising computer programs for handling handling a User Equipments, UE, access to networks are provided. A method performed by a mobility node 105 comprises, when the UE 101 accesses the current visited network 100v, transmitting 302, 401, through the visited network to a subscriber server 108 in a home network 100h of the UE 101, a request for access information for the UE 101. The request comprises network information which indicates the current visited network 100v and at least one potential visited network which the UE 101 can access. The method further comprises receiving 304, 403, from the subscriber server 108, the requested access information for at least some of the networks indicated in the request. The access information comprises allowed network IDs and corresponding allowed RATs for at least some of the networks indicated in the request which the UE 101 is allowed to access. When the UE 101 should access one of the potential visited networks, the mobility node determines 405, based on the previously received access information, if the UE 101 is allowed to access the potential visited network.
