The present invention relates to a method for operating a cellular radio network (100). According to the method, a predicted location information (203) relating to a user equipment (110) is determined. The predicted location information (203) comprises a predicted future location of the user equipment (110). Depending on the predicted location information (203) control information is determined. Based on the control information, a registering of the user equipment (110) at cells (101, 101A-101H) of the cellular radio network (100) is controlled.
