摘要： PROBLEM TO BE SOLVED: To eliminate a terminal operator's need for changing setting information of a radio terminal in roaming in a radio communication system in which setting information needed to connect to a radio channel is different in each radio base station.
SOLUTION: The radio terminal notifies, through a radio communication network for setting, a setting information management device of a radio channel connection request for requesting a radio base station existing at a movement destination to connect to a radio channel. The setting information management device notifies the radio terminal at the request source of setting information needed to connect the radio base station to the radio channel through the radio communication network for setting. The radio terminal sets the notified setting information in its own radio terminal, connects the radio base station with the radio channel and transmits and receives data to/from the radio base station. According to the system, the terminal operator receives a radio communication service without being aware of a change in hot spots resulting from moving.
