System and method of automatic call barring in a radio telecommunications network
First Claim
1. A method of reducing fraudulent use of a mobile identification number associated with a mobile station in a radio telecommunications network by making an initial determination to restrict the mobile station'"'"'s access to the network, said method comprising the steps of:
- assigning a first threshold value to an activity supervision period measured by a network timer located in a Home Location Register (HLR) associated with the mobile station, said first threshold value being a maximum time that the mobile station may be inactive; and
making the initial determination, before the mobile station is disabled by said network, to restrict call originations from the mobile station if the mobile station does not register with said network within the activity supervision period.

Abstract
A system for reducing fraudulent use of a mobile telephone number in a radio telecommunications network. The system automatically bars call originations from the mobile telephone if the mobile telephone does not register with the network for a predetermined time period, or if the mobile telephone does not originate a call for a second predetermined time period. The system determines when a mobile telephone originates a call, measures a predetermined time period with a timing mechanism, and starts the timing mechanism when the mobile telephone originates a first call. The system then determines whether a second call originated from the mobile telephone during the predetermined time period and restarts the timing mechanism at the time that the mobile telephone originates a second call upon determining that the second call originated from the mobile telephone during the predetermined time period. The system reauthorizes the mobile telephone to originate calls in the network upon verification of a personal identification number entered by the subscriber.

-
assigning a first threshold value to an activity supervision period measured by a network timer located in a Home Location Register (HLR) associated with the mobile station, said first threshold value being a maximum time that the mobile station may be inactive; and making the initial determination, before the mobile station is disabled by said network, to restrict call originations from the mobile station if the mobile station does not register with said network within the activity supervision period. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method of reducing fraudulent use of a mobile identification number associated with a mobile station in a radio telecommunications network by making an initial determination to restrict the mobile station'"'"'s access to the network, said method comprising the steps of:
-
assigning a threshold value to an originating call supervision period measured by a timer located in at least one of a Home Location Register (HLR) and a serving Mobile Switching Center (MSC) associated with said network, said threshold value being a maximum time period following a registration by the mobile station during which the mobile station must originate a call; and making the initial determination, before the mobile station is disabled by said network, to restrict call originations from the mobile station if the mobile station does not originate a call within the originating call supervision period. - View Dependent Claims (8, 9, 10)

11. A system for reducing fraudulent use of a mobile identification number associated with a mobile station in a radio telecommunications network by making an initial determination to restrict the mobile station'"'"'s access to the network, said system comprising:
-
a timer incorporated in a Home Location Register (HLR) associated with the mobile station, said timer for measuring an activity supervision period, said activity supervision period being a pre-determined maximum time that the mobile station may be inactive; and means for making the initial determination, before the mobile station is disabled by said network, to restrict call originations from the mobile station if the mobile station does not register with said network within the activity supervision period. - View Dependent Claims (12, 13, 14, 15, 16)

21. A system for reducing fraudulent use of a mobile telephone number in a radio telecommunications network serving a plurality of mobile telephones by making an initial determination to deny one of the mobile telephones access to the network, said system comprising:
-
means for determining when a mobile telephone originates a call; a timing mechanism that measures a predetermined time period, said timing mechanism incorporated in at least one of a Home Location Register (HLR) and a serving Mobile Switching Center (MSC) associated with the mobile station; means for starting said timing mechanism when said mobile telephone originates a first call; means for determining whether a second call originated from said mobile telephone during said predetermined time period; means for restarting said timing mechanism at the time that said mobile telephone originates a second call upon determining that said second call originated from said mobile telephone during said predetermined time period; and means for barring said mobile telephone from originating calls in said network while allowing others of said plurality of mobile telephones to continue originating calls, upon determining that no calls originated from said mobile telephone during said predetermined time period. - View Dependent Claims (22, 23, 24)
