The system information generating unit (20) generates system information including a system information message in which an emergency message is described, and the paging message generating unit (22) generates a paging message that further includes information indicating that the emergency message is present in the system information and an identifier that identifies a system information message in which the emergency message is described. Consequently, a wireless communication base station can be provided which is capable of urgently notifying system information to be broadcast at a schedule according to the urgency of the system information while suppressing modifications to the system information as much as possible.
