Wireless communication system and method, and dynamic association control apparatus and method

A dynamic association control method, comprising:

• an information acquisition step, for acquiring information related to an object relay node and to candidate base stations to be associated;
• a blocking probability calculation step, for calculating respectively a candidate blocking probability in a case where the object relay node performs associations with each of the candidate base station to be associated according to the acquired information;
• and
• an association control step, for selecting an object blocking probability from the calculated candidate blocking probabilities, and using 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.

A wireless communication method in a wireless communication system which includes base stations and relay nodes associated with base stations, the wireless communication method comprising:

• respectively acquiring, by the base stations and the relay nodes, information related to their respective communication environment;
• sending, by the base stations, the acquired information to each relay node which is capable of establishing association with the base stations;
• and
• selecting, by the relay nodes, candidate base stations to be associated from base stations except a currently associated base station, respectively calculating a candidate blocking probability when the present relay node performs association with each of the candidate base stations to be associated based on information from the base stations and the acquired information, selecting an object blocking probability from the candidate blocking probabilities calculated by the present relay node, using a base station corresponding to the object blocking probability as an object base station to which the association is transferred, and changing from current association with a base station to association with the object base station to which the association is to be transferred.
