    摘要： A radio base station eNB10-1 sends a Resource Status Request message for requesting initiation of transmission of a second load information to a radio base station eNB10-2 when a load level thereof is equal to or higher than a first threshold, and omits transmission of the Resource Status Request message for requesting initiation of transmission of the second load information when the load level thereof is lower than the first threshold. The radio base station eNB10-2 sends a Resource Status Update message including the second load information upon receipt of the Resource Status Request message for requesting initiation of transmission of the second load information.

    摘要： Upon receipt of an RLF Indication message indicating a failure in a handover where a radio base station eNB10-1 is the handover source from the other radio base station eNB, the radio base station eNB10-1 can recognize that its coverage is not adjusted appropriately by referring to the RLF Indication message. Moreover, the radio base station eNB10-1 can adjust coverage appropriately by expanding the radiation area of the antenna 101 whose radiation area is directed toward the other radio base station eNB being the handover target, among the antennas 101 included in the radio base station eNB10-1.
