摘要
In order to prevent illegal use of a mobile telephone, a call is repeatedly originated from a telephone or base station to the mobile telephone over a wireless path. When the call is received by the mobile telephone over the wireless path so that a communication channel is established, a destruction code including a cryptographic data is transmitted from the telephone or base station to said mobile telephone. The mobile telephone receives the destruction code and compares the cryptographic data of the received destruction code with a preset data stored in the mobile telephone to determine whether both the data are matched. When it is determined that both the data are matched, the mobile telephone destroys a telephone functioning information stored in the mobile telephone and necessary for performing communication.
