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.

PERIODIC RADIO USER CHECK IN WITH PERSONAL IDENTIFICATION CODE

patcher would also be able to send the PIC Definition and change the PIC, as a sort of dynamic password. This would be very useful in a situation where more than one user has access to the same radio. New ISWIOSW pairs will be added for PIC Definition/ACK. The PIC Definition will include the following information;

Radio LD / PIG Dehition j OLD PIG 1D I NEW PIG 1D

The PIC Definition ACK will include the following information:

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.

SOLUTION DESCRIPTION

  To solve the above problem, before a radio is put into the field, an initial PIC ID would be defmed by the dispatcher or manager. To change and personalize the code, the radio user would enter any preferred code by first entering the initial PIC followed by the new one. For SmartNet, the code (a 4 digit number between 0000-9999) may be restricted in size because of ISWlOSW size limitations. The code may be entered via a keyboard or magnetic card or any other input medium available. Upon a radio user's requesf the radio would send the PIC Definition ISW. The PIC Definition OSW would be received by the SmartNet system to be validated. If the Old PIC ID is indeed valid, the New PIC ID will be stored in the SmartNet database for More ve...
