ABSTRACT:
A method of processing location data at a portable computing device is provided and includes receiving information associated with a user defined location at the portable computing device. The information includes a central point and an entry indication perimeter. An entry alert associated with the user defined location is received at the portable computing device. The location of the portable computing device is monitored to determine when the portable computing device crosses the entry indication perimeter associated with the central point of the user defined location indicating that the portable computing device is proximate to the user defined location. The method further includes switching the portable computing device from a roaming state to an entry state indicating that the portable computing device is about to enter the user defined location. An indication can be provided to the user that the portable computing device has switched to the entry state.
