MOBILE COMMUNICATION METHOD, MOBILE COMMUNICATION SYSTEM AND RADIO BASE STATION

摘要

When congestion in an eNB is detected, effective utilization of resources is achieved by adjusting not only a data flow rate in an EPS-RAB but also a band of a core network bearer corresponding with the EPS-RAB. A mobile communication method according to an embodiment includes a step A of causing an eNB to notify an MME of a cause of congestion and identifier information of the EPS-RAB involved in the congestion, when the eNB detects the congestion.
