Abstract: A system for configuring a UE-AMBR includes a MME to send the UE-AMBR to an eNB covering the serving cell of the UE, the eNB covering the serving cell of the UE establishes a radio access bearer of the UE on at least one secondary cell. The MME sends an AMBR of the UE in the primary eNB covering the serving cell of the UE and an AMBR of the UE in a secondary eNB to the primary eNB. The primary eNB sends the AMBR of the secondary eNB to the corresponding secondary eNB. The technical solutions of the present disclosure can make total rate of all non-GBR services of the UE be not larger than the UE-AMBR when the UE has multiple S1 bearers or one S1 bearer.
