Abstract:
A mobile communication system (100) includes: a plurality of radio base stations (111-11n) each transmitting a setting request including identification information of the radio base station itself and group identification information identifying a group to which the radio base station belongs; a gateway apparatus (120) connected to the plurality of radio base stations (111-11n), the gateway apparatus (120) associating the identification information and the group identification information included in the setting request with each other upon receipt of the setting request and storing as distribution destination information; and a switching center (130) transmitting, to the gateway apparatus (120), a distribution request including the group identification information of a group being a target to distribute an emergency early warning. When the gateway apparatus (120) has received the distribution request, the gateway apparatus (120) specifies at least one radio base station associated with the group identification information included in the distribution request out of the distribution destination information, and transfers the distribution request to the specified radio base station. When the distribution request has been transferred from the gateway apparatus (120), the radio base station distributes the emergency early warning to a subordinate cell.
