Patent 06131032 - Method and apparatus for monitoring users of a communications system > Claims

  • 1. A method of operating a switch in a cellular communications system, said method comprising the steps of:nreceiving by the switch a call request from a calling party;nsending by the switch calling party information to a register, said register including information relating to monitoring criteria based upon physical location of a party to a call;nreceiving by the switch intercept information from said register, said intercept information includes information regarding whether the call should be intercepted; andnrouting said call request.
    • 2. The method of claim 1 further comprising the step of:nresponsive to said intercept information, routing said call request to an intercepting party.
    • 3. The method of claim 1 wherein said intercept information includes call intercept routing instructions.
    • 4. The method of claim 1 wherein said calling party information includes calling party location information.
    • 5. The method of claim 1 further comprising the step of:nprior to said step of receiving intercept information, sending called party information to said register.
      • 6. The method of claim 5 wherein said called party information includes called party location information.
  • 7. A method of operating a switch in a cellular communications system, said method comprising the steps of:nreceiving a call request for a call from a calling party;nsending called party information to a register, said register determining from an intercept list located within said register, based on said call party location information, whether said call request requires monitoring;nreceiving intercept information from said register, said intercept information includes a field that specifies whether the call should be intercepted; andnrouting said call request.
    • 8. The method of claim 7 further comprising the step of:nresponsive to said intercept information, routing said call request to an intercepting party.
    • 9. The method of claim 7 wherein said intercept information includes call intercept routing instructions.
    • 10. The method of claim 7 wherein said called party information includes called party location information.
      • 11. The method of claim 10 further comprising the step of prior to said step of receiving intercept information, sending calling party information to said register.
        • 12. The method of claim 11 wherein said calling party information includes calling party location information.
    • 13. The method of claim 7 wherein said party to a call information includes calling party location information.
  • 14. A method of operating a monitoring location register, said method comprising the steps of:nreceiving call request information associated with a call, said call request information includes a calling party location or a called party location; andnresponsive to said call request information, sending call intercept information.
    • 15. The method of claim 14 wherein said call intercept information includes a field specifying whether the call should be intercepted.
    • 16. The method of claim 14 further comprising the step of prior to said step of sending, searching a database of parties to retrieve said call intercept information.
  • 17. A method of maintaining intercept lists comprising the steps of:nreceiving intercept information into a master intercept list, said master intercept list being maintained within a monitoring location register; andndisbursing said intercept information to a plurality of switches wherein each of said plurality of switches includes a local intercept list.
  • 18. A method of updating an intercept list comprising the steps of:na switch receiving a user identification from a user;nsaid switch querying a monitoring location register with said user identification;nsaid monitoring location register sending an intercept list entry to said switch; andnsaid switch updating an intercept list included in said switch with said intercept list entry.
    • 19. The method of claim 18 further comprising the step of:nprior to said querying step, said switch receiving call request information from said user;nand wherein said querying step further comprises the step of querying said monitoring location register with said call request information.
    • 20. The method of claim 18 where said user identification includes information relating to said user's current location.
  • 21. A monitor location register comprising:na data storage device for storing user intercept information, said storage device including an intercept list, said intercept list including a plurality of intercept records, said intercept records including a location data field denoting physical locations in which a user named in user identification data may be monitored by a monitoring authority;nan input interface for receiving call request information; andnan output interface for sending said user intercept information.
    • 22. The monitoring location register of claim 21 wherein said intercept records include calling party location information.
    • 23. The monitoring location register of claim 21 wherein said intercept records include called party location information.
    • 24. The monitoring location register of claim 21 wherein said intercept records include a monitoring party identity.
    • 25. The monitoring location register of claim 21 wherein said intercept records include intercept call routing instructions.
    • 26. The monitoring location register of claim 21 wherein said input interface is for receiving call request information from a single switch.
    • 27. The monitoring location register of claim 21 wherein said input interface is for receiving call request information from multiple switches .
