description The present invention relates to a radio resource controller (220a) for controlling radio resources of a serving radio access node (100a). The controller is configured to assign particular radio resources of the serving radio access node to a radio communication session established between the serving radio access node and a particular mobile station, and to push session information (UE_id; UE_ctx_ptr) of the radio communication session into a common data repository (320) accessible to a further radio resource controller (220b) controlling radio resources of a further radio access node (100b). The session information comprise a mobile identifier (UE_id) that may be used by the particular mobile station for resumption of the radio communication session, and further allow retrieval of contextual communication parameters (UE_ctx) used by the serving radio access node for radio communication with the particular mobile station during the radio communication session. The radio resource controller and the further ra
