Provided is a wireless communication system that does not allow a third party to use a duplicated radio wave to establish communication with a mobile station. In step S101, a base station 100 sends "notification information" to a mobile station 200. In step S102, the mobile station 200 sends back to the base station 100 a "registration request" setting a scramble code C. A predetermined scramble code A is used in the "notification information" and the "registration request" for scrambling. In step S103, the base station 100 sends a "registration response" back to the mobile station 200. In step S104, the mobile station 200 sends a "response confirmation" back to the base station 100. A predetermined scramble code C set in the "registration request" is used in the "registration response" and the "registration response" for scrambling. When the base station 100 receives the "response confirmation", communication is established between the base station 100 and the mobile station 200, and scrambling is implemented using the scramble code C when signals are transmitted thereafter. |
