A computing apparatus for a radio access network, wherein the computing apparatus is configured to communicate with a wireless communication system, the computing apparatus comprising a processor, characterized in that the processor is configured to: acquire tracking information including the position and/or velocity of a first, second and third user node (404, 406, 408); determine at a first point in time a first quality measurement of a first radio link between the first user node and a first remote radio unit; detect from the first quality measurement a first disturbance to a Line of Sight, LoS, of the first radio link; determine at a second point in time a second quality measurement of a second radio link between the second user node and a second remote radio unit; detect from the second quality measurement a second disturbance to the LoS of the second radio link; estimate a position and a velocity of a moving physical disturbance causing first and second disturb to the radio links; predict a point in time when the moving physical disturbance interferes the LoS of a third radio link between the third user node and a third remote radio unit based on the tracking information and the estimation; and direct the third user equipment to handoff to another remote radio unit before the predicted point in time; wherein the processor is configured to identify the physical disturbance as a moving physical disturbance (PDm) by identifying a group of user nodes having well correlated velocities, wherein an average velocity of the group of user nodes is greater than a predetermined threshold value, and wherein the velocity of all the user nodes in the group is within a predetermined velocity of the average velocity of the group. acquire tracking information including the position and/or velocity of a first, second and third user node (404, 406, 408); determine at a first point in time a first quality measurement of a first radio link between the first user node and a first remote radio unit; detect from the first quality measurement a first disturbance to a Line of Sight, LoS, of the first radio link; determine at a second point in time a second quality measurement of a second radio link between the second user node and a second remote radio unit; detect from the second quality measurement a second disturbance to the LoS of the second radio link; estimate a position and a velocity of a moving physical disturbance causing first and second disturb to the radio links; predict a point in time when the moving physical disturbance interferes the LoS of a third radio link between the third user node and a third remote radio unit based on the tracking information and the estimation; and direct the third user equipment to handoff to another remote radio unit before the predicted point in time; wherein the processor is configured to identify the physical disturbance as a moving physical disturbance (PDm) by identifying a group of user nodes having well correlated velocities, wherein an average velocity of the group of user nodes is greater than a predetermined threshold value, and wherein the velocity of all the user nodes in the group is within a predetermined velocity of the average velocity of the group.
