Method, Apparatus and System for Key Derivation

摘要

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.

1. A base station functioning as a source base station for a user equipment (UE), comprising:
a receiver configured to receive a measurement report from a UE; a processor configured to make a handover decision and to derive multiple keys corresponding to multiple cells of a target base station for the UE; and a transmitter configured to send a handover request message to the target base station for the UE, the handover request message comprising the multiple keys.
