摘要

PURPOSE: A method for encoding a control signal is provided to generate an additional security key except an MAC message authentication code or encode control signaling through a pre-defined TEK(Traffic Encryption Key). CONSTITUTION: A subscriber mobile station transmits a registration request message(S101). A base station transmits a registration response message(S102). The subscriber mobile station transmits a TFTP-CPLT(config File TFTP complete) message(S103). The base station transmits a TFTP-RSP message(S104). The subscriber mobile station transmits a DSx-REQ message(S105). The base station transmits a DSx-RSP message(S106). The subscriber mobile station transmits a DSx-ACK message(S107).
