Method for avoiding fraudulent use of a mobile radiotelephone by blocking an interface after a certain inactive period of time and mobile radiotelephone performing the same |
摘要 |
A telephone includes circuits that enable a user of the telephone to receive incoming calls and set up outgoing calls. A controller puts the telephone interface in a blocking state to prevent normal use of the telephone when the interface receives a block signal, and puts the interface in a service state to make the telephone accessible. The telephone has a timing circuit that supplies the block signal to the controller after a given period of inactivity of the telephone to place the telephone in the blocking state. An erroneous unblocking code used a predetermined number of times puts the telephone in a state of total block which includes a power cut of the telephone. Turning on the telephone allows leaving the total block state.
