Abstract

The present invention provides a method for determining if a mobile unit is transient. An MSC receives a location event including a cell site and a time from a mobile unit. The MSC compares the time of the location event with the time of a previous location event for the current cell to get a time difference. If the time difference is greater than the predetermined value, the MSC indicates that the mobile unit is transient.

Claims

1. A method for determining if a mobile unit is transient comprising:

receiving a location event from a mobile unit, the location event including a time of the location event;

comparing the time of the location event with the time of a previous location event to get a time difference;

determining if the time difference is greater than a predetermined value; and

if the time difference is greater than the predetermined value, indicating that the mobile unit is transient.

2. A method for determining if a mobile unit is transient in accordance with claim 1, wherein the location event is a message sent from the mobile unit to a Mobile Switching Center.

3. A method for determining if a mobile unit is transient in accordance with claim 1, wherein the location event is a registration message sent from the mobile unit to a Mobile Switching Center.

4. A method for determining if a mobile unit is transient in accordance with claim 1, wherein the location event is a handoff message sent from the mobile unit to a Mobile Switching Center.

5. A method for determining if a mobile unit is transient in accordance with claim 1, wherein the location event is a time-based registration message sent from the mobile unit to a Mobile Switching Center.

6. A method for determining if a mobile unit is transient in accordance with claim 1, the method further comprising the step of updating a paging record with the information from the current location event.

7. A method for determining if a mobile unit is transient in accordance with claim 1, wherein the predetermined value is twenty four hours.

8. A method for determining if a mobile unit is transient in accordance with claim 5, wherein the predetermined value is greater than a length of an autonomous registration message.

9. A method for determining if a mobile unit is transient in accordance with claim 1, the method further comprising the step of storing an identifier of the mobile unit in a transient mobile unit database if the time difference is greater than the predetermined value.

10. A method for determining real-time traffic conditions utilizing transient mobile units, the method comprising:

receiving a location event from a mobile unit, the location event including a time of the location event;

comparing the time of the location event with the time of a previous location event to get a time difference;

determining if the time difference is greater than a predetermined value;

if the time difference is greater than the predetermined value, indicating that the mobile unit is transient; and

storing information pertaining to the mobile unit.

11. A method for determining real-time traffic conditions utilizing transient mobile units in accordance with claim 10, wherein the step of storing information pertaining to the mobile unit comprises storing the velocity of the mobile unit.

12. A method for determining real-time traffic conditions utilizing transient mobile units in accordance with claim 10, determining a traffic time utilizing the velocity of the mobile unit.

13. A method for determining real-time traffic conditions utilizing transient mobile units, the method comprising:

retrieving information pertaining to a plurality of transient mobile units; and

utilizing the information pertaining to the plurality of transient mobile units to determine real-time traffic conditions.

14. A method for determining real-time traffic conditions utilizing transient mobile units in accordance with claim 13, wherein the information pertaining to a plurality of transient mobile units comprises the velocity of each of the plurality of transient mobile units.

15. A method for determining real-time traffic conditions utilizing transient mobile units in accordance with claim 13, the method further comprising the step of utilizing the information pertaining to the plurality of transient mobile units to determine an optimal route of travel from a first location to a second location.
