System and method for employing a telecommunications network to remotely disable a SIM or smartcard
First Claim
1. In a card having a subscriber identity module (SIM) that cooperates with a mobile station to effect communication with a telecommunications network, a system for disabling said card, comprising:
- data communications circuitry that transmits a code uniquely identifying said card from logic circuitry within said card to said telecommunications network via said mobile station, said code employable by said telecommunications network to search a disable database associated therewith, said telecommunications network returning a disable command if said code is found in said disable database; and
disabling circuitry that incapacitates said logic circuitry to prevent an operation thereof, said card being incapacitated with respect to said telecommunications network and systems independent of said telecommunications network.

Abstract
In a smartcard having a subscriber identity module ("SIMI") that cooperates with a mobile station to effect communication with a telecommunications network, a system for, and method of, disabling the smartcard. The system includes: (1) data commnications circuitry that transmits a code uniquely identifying the smartcard from logic circuitry within the smartcard to the telecommunications network via the mobile station, the code employable by the telecommunications network to search a disable database associated therewith, the telecommunications network returning a disable command if the code is found in the disable database and (2) disabling circuitry that incapacitates the logic circuitry to prevent an operation thereof, the smartcard being incapacitated with respect to the telecommunications network and systems independent of the telecommunications network.

8. For use in a card having a subscriber identity module (SIM) that cooperates with a mobile station to effect communication with a telecommunications network, a method of disabling said card, comprising the steps of:
-
transmitting a code uniquely identifying said card from logic circuitry within said card to said telecommunications network via said mobile station, said code employable by said telecommunications network to search a disable database associated therewith; receiving a disable command from said telecommunications network if said code is found in said disable database; and incapacitating said logic circuitry to prevent an operation thereof, said card being incapacitated with respect to said telecommunications network and systems independent of said telecommunications network. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A telecommunications network capable of communicating with a plurality of mobile stations, each of said plurality of mobile stations cooperating with a card having a subscriber identity module (SIM) to effect communication with said telecommunications network, said telecommunications network comprising:
-
a disable database that contains a plurality of codes corresponding to a plurality of cards that are to be disabled; data communications circuitry that receives a code uniquely identifying one of said plurality of cards, said telecommunications network searching said disable database for said code, said data communications circuitry transmitting a disable command to said one of said plurality of cards if said code is found in said disable database; and disabling circuitry within said one of said plurality of cards that incapacitates logic circuitry therein to prevent an operation thereof, said card being incapacitated with respect to said telecommunications network and systems independent of said telecommunications network. - View Dependent Claims (16, 17, 18, 19, 20)
