The invention relates to a method for supporting a handover of a user equipment (15) from a first radio access network (11) to a second radio access network (13). In order to ensure the success of the handover, it is proposed that a core network stores at least for some user equipment (15) a list identifying all radio access networks, (11, 13) to which the respective user equipment (15) is allowed to be handed over. The core network can then transmit the information stored for a specific user equipment (15) to the first radio access network (11) (step c), so the first radio access network (11) can determine reliably before carrying out a handover by which other radio access network (13) a handover will be accepted. The invention equally relates to a core network, a network element of a core network and a network element of a radio access network that are designed for carrying out the proposed method.
