An RNC server issues an encryption start instruction to a media gateway (MG) and a terminal. The MG and terminal, which have received the encryption start instruction, encrypt U-Plane information using a predetermined secret key, and adds a predetermined encryption start bit to the encrypted U-Plane information for transmission to a communication partner. The communication partner, upon detection of the encryption start information, decrypts the received U-Plane information using the predetermined secret key.
