Abstract

Methods and apparatus are presented herein for controlling the degree of precision with which geographic information is reported to a requesting entity. A precise geographic location is used to determine an adjusted geographic location, which is then transmitted to the requesting entity rather than the precise geographic location.

Claims

1. A method for selectively transmitting a target location to a requesting entity, comprising:

determining the target location;

determining a distance value associated with the target location; and

if the target location is a location that is greater than or equal to the distance value away from a previous location, then transmitting the target location to the requesting entity.

2. The method of claim 2, further comprising:

if the target location is a location that is less than the distance value away from a previous location, then determining a second distance value associated with the target location; and

if the target location is a location that is greater than or equal to the second distance value away from a waypoint, then transmitting the target location to the requesting entity.

3. A method for selectively transmitting a target location to a requesting entity, comprising:

determining the target location;

determining a distance value associated with the target location; and

if the target location is a location that is greater than or equal to the distance value away from a waypoint, then transmitting the target location to the requesting entity.

4. The method of claim 3, further comprising:

if the target location is a location that is less than the distance value away from a waypoint, then determining a second distance value associated with the target location; and

if the target location is a location that is greater than or equal to the second distance value away from a previous location, then transmitting the target location to the requesting entity

5. A method for selectively transmitting a target location to a requesting entity, comprising:

determining the target location;

determining a speed of the target;

determining a predetermined speed limit of the target in accordance with the target location; and

if the speed of the target exceeds the predetermined speed limit of the target, then transmitting the target location to the requesting entity.

6. A method for selectively transmitting a target location to a requesting entity, comprising:

determining the target location;

determining whether the target location is located in an area with peak capacity loads or in an area with off-peak capacity loads;

if the target location is located in an area with peak capacity loads, then transmitting the target location at a reduced rate; and

if the target location is located in an area with off-peak capacity loads, then transmitting the target location at a normal or an increased rate.

7. A method for determining when to transmit a target location to a requesting entity, comprising:

determining whether a first threshold value associated with a distance-based reporting scheme has been crossed;

determining whether a second threshold value associated with a waypoint-based reporting scheme has been crossed; and

if the first threshold value or the second threshold value has been crossed, then transmitting the target location to the requesting entity.

8. The method of claim 7, further comprising:

determining whether a third threshold value associated with a proximity-based reporting scheme has been crossed; and

if the third threshold value is crossed, then transmitting the target location to the requesting entity.

9. The method of claim 8, further comprising:

determining whether a fourth threshold value associated with a speed-based reporting scheme has been crossed; and

if the fourth threshold value is crossed, then transmitting the target location to the requesting entity.

10. An apparatus for determining when to transmit a target location to a requesting entity, comprising:

means for determining whether a first threshold value associated with a distance-based reporting scheme has been crossed;

means for determining whether a second threshold value associated with a waypoint-based reporting scheme has been crossed;

means for determining whether a third threshold value associated with a proximity-based reporting scheme has been crossed;

means for determining whether a fourth threshold value associated with a speed-based reporting scheme has been crossed; and

means for transmitting the target location to the requesting entity if the first threshold value, the second threshold value, the third threshold value, or the fourth threshold value has been crossed.
