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: Methods for avoiding handover failure are provided. The method includes determining, by a source Base Station (BS), to perform a handover of a User Equipment (UE); determining, by the source BS, whether a target BS connects with a user plane node serving the UE at the source BS; and releasing resources, when the target BS does not connect with the user plane node serving the UE at the source BS.

Abstract: The present application discloses a method for synchronizing encryption information between a SCell and UE, which includes that: the SCell transmits a COUNT value of RB established for the UE to a PCell; the PCell transmits the COUNT value received from the SCell to the UE; and the PCell receives a COUNT value of RB established on the SCell that is saved by the UE from the UE. Or, the SCell and the UE may directly exchange the COUNT value of RB. By the present application, the security and correctness of data can be ensured.

Abstract: A method for supporting indication of a failure event to a source access system is provided. The method includes notifying, by the source access system, information of a source cell to a target access system, routing, by the target access system, a message to the base station or the base station controller of the source access through a core network by use of the information of the source cell received from the source access system when the target access system needs to transmit a message to the source access system. By use of the method provided by the present disclosure, a problem of mobility robustness optimization (MRO) among different radio access technology (RAT) may be notified to the source access system, so as to avoid impact for a terminal, reduce operator configuration.
