Abstract: A control method implemented by a computer operable as one of a plurality of processing nodes arranged in a redundant configuration in a first blockchain, the control method including: detecting generation of transaction data related to a first transaction in the first blockchain stored in each of the processing nodes; and controlling whether or not to transmit a second transaction to be executed after the first transaction to a second blockchain on a basis of the detected transaction data.

Abstract: An object of the invention is to control an incoming call response operation on the basis of the movement speed of a radio telephone apparatus. In a radio communication system including a plurality of base stations, a multiplicity of mobile stations and a network control station (exchange station) that controls these stations, a radio telephone apparatus is used as a mobile station and performs radio communication with a base station through an antenna. A base station ID management circuit monitors a base station which can perform radio communication and grasps a the condition of the connection with the base station. A base station ID switching frequency counting circuit counts the number of times N the communication possible base station has been switched within a unit time counted by a timer counter. A control circuit compares N and a reference number of times N0 and judges that the radio telephone apparatus is moving at high speed when N>N0.
