A technique for controlling radio access provided by cells of a radio access network, RAN (500), to radio devices (802) is described. As to a method aspect of the technique, the method (300) comprises or initiates a step of selectively sending (304), depending on an overload status of a first cell (100) of the RAN (500), a message (502) to at least one second cell (200) in the RAN (500). The at least one second cell (200) is a neighbor cell of the first cell (100). The message (502) comprises blocking information configured to trigger the at least one second cell (200) to refrain from sending, to the first cell (100), a request for providing radio access to at least one of the radio devices (802).
