When setting up communication from a user equipment UE (1), such as for providing IP access for the UE in order to allow it to use some service, information or an indication or at least one network properly relating to a first network, e.g. the current access network (3, 3′), is sent to the UE from a node (13) in a sue and network such as the home network (5) of the subscriber ask UE. The information or indication can be sent in a first stage of an authentication procedure being part of the setting up of a connection from the UE. In particular, the network property can indicate whether the access network (3, 3′) is trusted or not.
