Radio network controller capable of handling over ciphering information from one to another

In a radio network controller (RNC) (2), a control portion (22) reads ciphering parameter from a protocol processing portion (231) for performing a protocol processing of FP (Frame Protocol) and MAC (Medium Access Control) and sets the ciphering parameter in another protocol processing portion (232). By handing over the ciphering parameter from the protocol processing portion (231) to the other protocol processing portion (232), a telephone call is continued and a user equipment (UE) 41 is not conscious of handover of processing.
