Abstract:
A radio base station distributes an emergency alert to a plurality of system information messages such that the number of system information messages is odd. The radio base station then periodically transmits, to mobile stations, a system information block including scheduling information indicating a transmission schedule of the system information messages to which the emergency alert has been distributed. The radio base station also periodically transmits, to the mobile stations, a paging message indicating that the radio base station transmits, to the mobile stations, the system information message to which the emergency alert has been distributed. Further, according to the scheduling information, the radio base station periodically transmits, to the mobile stations, the system information message to which the emergency alert has been distributed.
