To achieve a secure and fast handover in a distributed mobile communication environment ( 10 ), the control functionality is lying at the borderline between wireless and wire-bound communication network elements, and it is proposed to, firstly, execute a mutual authentication between a mobile device ( 26 ) and a new access point ( 14 ) using security context information previously transmitted to the new access point. Then, after successful mutual authentication, a handover will be executed from the current access point ( 12 ) to the new access point ( 14 ).
