Abstract

PROBLEMS SOLVED A basic function provided by existing radio control systems like SmartNet is the ability to Inhibit a radio which has been lost or stolen. However, there is currently no easy way to determine that a radio is indeed missing. In especially sensitive situations, it is imperative that a missing radio be identified and taken out of action as soon as possible. While a Radio Check can quickly ver- ify that a radio is active in the system, it can not ensure that the individual holding the radio is indeed the legiti- mate user. A radio handshaking is needed where the system would send a signal and the radio user would respond with a predetermined password. It is suggested to enable signalling a radio user to enter a Personal Iden- tification Code (PIG) and con&m his legitimacy. The definition of the PIC could be done by the radio user and could be changed at will. An invalid code would indicate that the radio is not being operated by the intended user and should be Inhibited. Optionally, entering a correct PIC would cause an XInhibit to be sent to the radio. Another option would be to have a request for PIC with the option of automatic Inhibit after a period of time.
