A radio communication method for a radio communication system, the radio communication system including a base station provided with a plurality of radio communication units for which different communication schemes are settable, and a terminal station representing a type of terminal station and configured to perform radio communication by using a specific communication scheme, the radio communication method comprising: setting, at the base station, for the radio communication units, different communication schemes based on a setting policy for each type of terminal station so that any type of terminal station can be connected to any of the radio communication units; setting, by the base station, the setting policy and a switching policy for use in selecting a radio communication unit among the plurality of radio communication units for the type of terminal station; and in a case where the base station determines that the terminal station newly establishes a connection or a reconnection with the base station or is already connected to the base station and is to be switched to another radio communication unit: collecting, at the base station from the terminal station, communication scheme information on the specific communication scheme selectable by the terminal station; selecting, at the base station, a radio communication unit to which the terminal station is to be connected, in accordance with the communication scheme information, the setting policy, and the switching policy; and updating, at the base station, the setting policy and the switching policy for the radio communication unit based on the communication scheme information. setting, at the base station, for the radio communication units, different communication schemes based on a setting policy for each type of terminal station so that any type of terminal station can be connected to any of the radio communication units; setting, by the base station, the setting policy and a switching policy for use in selecting a radio communication unit among the plurality of radio communication units for the type of terminal station; and in a case where the base station determines that the terminal station newly establishes a connection or a reconnection with the base station or is already connected to the base station and is to be switched to another radio communication unit: collecting, at the base station from the terminal station, communication scheme information on the specific communication scheme selectable by the terminal station; selecting, at the base station, a radio communication unit to which the terminal station is to be connected, in accordance with the communication scheme information, the setting policy, and the switching policy; and updating, at the base station, the setting policy and the switching policy for the radio communication unit based on the communication scheme information. collecting, at the base station from the terminal station, communication scheme information on the specific communication scheme selectable by the terminal station; selecting, at the base station, a radio communication unit to which the terminal station is to be connected, in accordance with the communication scheme information, the setting policy, and the switching policy; and updating, at the base station, the setting policy and the switching policy for the radio communication unit based on the communication scheme information.
