The present disclosure presents method, network nodes and computer program for improving a dual band user equipment, UE/STA, mobility from a first access node, e.g. an eNB, arranged to operate according to a first radio access technology to at least one second access node, e.g. a WLAN AP, arranged to operate according to a second radio access technology. A communications interface is arranged for direct communication between the first access node and the respective second access node. The method, as performed in the first access node, comprises retrieving (S32) resource management related information of the second access node relevant for the user equipment UE/STA over the communications interface. Radio resources provided to the dual-mode user equipment, UE/STA, by both the first and the second access node, are coordinately controlled (S33), over the communications interface, based on the retrieved resource management related information and internal resource management related information for the first node.
