Abstract
Proposed is a technique for preparing a roaming operation of a User Equipment (UE) between a home network and at least one visited network. A method aspect being performed in a roaming control entity comprises receiving at least one message related to the roaming operation, determining if a roaming attempt from the home network to the at least one visited network is performed, and, if the determining step is affirmative, requesting, from the home network, information relating to the UE so as to evaluate if the UE has access to the home network. The method aspect being performed in the UE comprises transmitting the at least one message about the roaming attempt, and receiving, responsive to the transmitting, deny or grant of access of the UE to the at least one visited network depending on whether the UE has access to the home network or not.
