Abstract: Method, apparatus and systems are provided for key derivation. A target base station receives multiple keys derived by a source base station, where the keys correspond to cells of the target base station. The target base station selects a key corresponding to the target cell after obtaining information regarding a target cell that a user equipment (UE) is to access. An apparatus for key derivation and a communications system are also provided.

Abstract: A method, an apparatus and a system for key derivation are disclosed. The method includes the following steps: a target base station) receives multiple keys derived by a source base station, where the keys correspond to cells of the target base station; the target base station selects a key corresponding to the target cell after knowing a target cell that a user equipment (UE) wants to access. An apparatus for key derivation and a communications system are also provided.
