A wireless communications connection control method that enables flexible reconstruction of a wireless communications network system structure. The wireless communications connection control method comprising the steps of retaining in advance a node registration table in which the inter-node distance and node types are associated with each node; issuing a joining notification, together with the inter-node distance, in response to when a new node joins the wireless communications system; refreshing the node registration table according to the joining notification, determining whether it is necessary to change the node type based on the inter-node distance stored in the node registration table, and changing the node type stored in the node registration table when it is determined that the type needs to be refreshed.
