Abstract

See full text

A cellular radio system comprises terminals (401, 402) arranged to transmit a specific message of a predetermined form at least two times (408, 409; 413, 414), so that there is a predetermined time-out between the two successive messages of said form. A message of said form, which is received from a terminal, is attached (503, 507, 509) to a code representing the terminal in order to identify an illegal terminal. Such a terminal is regarded as identified (513, 514) for which the time between the reception of the two successive messages of said form attached to the code representing the terminal is shorter than said time-out.
