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.
