Abstract
A communication method for use in a radio communications system in which a mobile station sends identical data to a plurality of radio base stations in a parallel fashion. The method determines which radio base stations should stop forwarding data to an intermediate network device managing them. The intermediate network device includes a monitor and a controller. The monitor checks continuity of sequence numbers affixed to data received from each radio base station, thereby detecting missing sequence numbers. Based on the statistics of missing sequence numbers, the controller selects which radio base station should be allowed to continue its data forwarding operation. The controller then requests the other, non-selected radio base stations to stop their data forwarding operation.
