Abstract: The present application discloses a method for configuring and transmitting a key, which includes that: a) a serving cell (PCell) of UE determines a key (KeNB) used by a SCell and transmits the KeNB to the SCell; and b) the PCell transmits configuration information for configuring the SCell to the UE after receiving a response message from the SCell, and receives a response message from the UE. Or, the method includes that: a SCell of UE transmits a cell key request to a MME and receives key information from the MME; and the SCell transmits the key information received from the MME to the UE, and receives a response message from the UE. By the present application, data of the SCell is transmitted after being encrypted, so as to avoid a case that the data is decoded by other users, and further guarantee the security of the data.

Abstract: A method for supporting fast recovery of a User Equipment (UE) includes performing, by a serving base station, UE context synchronization for one or more other base stations in a related small cell cluster when a UE accesses the serving base station, performing, by a base station that the UE performs a radio resource control (RRC) connection re-establishment, the RRC connection re-establishment for the UE according to UE context saved in a synchronization process. The present also discloses another method and system for supporting UE fast recovery. By applying the technical solution disclosed by the present disclosure, when the UE moves in a small cell scenario, the UE can be recovered quickly in the case of a failure, so as to avoid the UE returns to an idle mode, avoid data loss, guarantee business continuity, and improve UE experience.

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.

Abstract: Examples of the present disclosure provide a method for determining access control, applied in a handoff procedure of a UE. The method includes: if a current service is a LIPA@LN service, and if the UE is in a same local network before and after the handoff, keeping, by a node performing access control determination, service continuity of the LIPA@LN service; if the UE moves out of the local network after the handoff, deactivating, by the node performing the access control determination, the LIPA@LN service; if the current service is a SIPTO@LN only service or a SIPTO@CN@LN service, if the UE is in the same local network before and after the handoff, keeping, by the node performing the access control determination, the service continuity of the SIPTO@LN only service or the SIPTO@CN@LN service; if the UE moves out of the local network after the handoff, determining, by the node performing the access control determination, whether to keep the service continuity of the SIPTO@LN only service or the SIPTO@CN@LN service according to a network policy. According to the technical solution provided by the present disclosure, service continuity of the LIPA service or the SIPTO service can be maintained correctly.
