SELECTIVE DELIVERY OF PRESENCE MESSAGES FOR WIRELESS COMMUNICATION DEVICES

摘要

A wireless communication system generates operating information indicating if a monitoring wireless communication device is in active mode or in idle mode for a wireless data service. The wireless system receives location information that indicates geographic locations of a monitored wireless communication device for delivery to the monitoring wireless communication device. The system stores the location information if the monitoring wireless communication device is in idle mode. The system wirelessly transfers the location information to the monitoring wireless communication device if the monitoring wireless communication device is in active mode. If the monitoring wireless communication device transitions from idle mode to active mode and has stored location information, the system generates summary location data for the monitored wireless communication device based on the stored location information and wirelessly transfers the summary location data to the monitoring wireless communication device.

主权项

1. A method of operating a wireless communication system to communicate with a monitoring wireless communication device that is tracking a monitored wireless communication device, the method comprising:
in the wireless communication system, generating operating information that indicates if the monitoring wireless communication device is in an active mode when a wireless data service is in use or in an idle mode when the wireless data service is not in use; in the wireless communication system, receiving location information that indicates geographic locations of the monitored wireless communication device for delivery to the monitoring wireless communication device; in the wireless communication system, storing the location information if the monitoring wireless communication device is in the idle mode and wirelessly transferring the location information to the monitoring wireless communication device if the monitoring wireless communication device is in the active mode; and in the wireless communication system, if the monitoring wireless communication device transitions from the idle mode to the active mode with the stored location information, then generating summary location data for the monitored wireless communication device based on the stored location information and wirelessly transferring the summary location data to the monitoring wireless communication device.
