CALL DROP AVOIDANCE DURING RADIO LINK FAILURE

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 radio resource controller would run on a common computer platform as two respective process instances. The computer platform would further hold the common data repository.
