In blockchain-based radio access network sharing (BRAN), users can use various wireless systems without a centralized control station by making connection contracts between a piece of user equipment (UE) and wireless base station (BS) using a blockchain. Since the contracts are made autonomously, the number of UEs accommodated may be biased, and the utilization efficiency of the entire wireless system may decrease. We propose a method of smoothing the number of accommodated UEs by controlling the connection parameters using the user-transition information between wireless BSs and the current number of accommodated UEs. These information are extracted on the blockchain ledger that can be referred to by each BS, eliminating the need for private information such as location. Computer simulations revealed that the proposed method suppressed the bias of the number of accommodated UEs by each BSs by about 5 %. Also, proposed method improved the median downlink throughput by about 2.8 times compared with a conventional method.
