  • Wireless communication system and method, and dynamic association control apparatus and method
    Patent number: 9801093
    Abstract: It is provided a dynamic association control apparatus comprising: an information acquisition part configured to acquire information related to an object relay node and to candidate base stations to be associated; a blocking probability calculation part configured to calculate respectively a candidate blocking probability in a case where the object relay node performs association with each of the candidate base stations to be associated according to the acquired information; and an association control part configured to select an object blocking probability from the calculated candidate blocking probabilities, and use a base station corresponding to the selected object blocking probability as an object base station to which the association is transferred, so that the object relay node changes to be associated with the object base station to which the association is transferred.
