Radio communication system, radio base station, radio terminal, and communication control method

摘要

A radio communication system includes a first radio base station corresponding to a first radio communication scheme and a second radio base station corresponding to a second radio communication scheme. The first radio base station transmits a first switching request notification for requesting switching of a connection to the second radio base station to a radio terminal connected to the first radio base station when emergency information associated with an emergency situation from an upper network has been received. The radio terminal transmits, to the second radio base station, a connection request notification for requesting a connection to the second radio base station when the first switching request notification has been received.
