<p>A communication system (110, 310) is disclosed for communicating a presence message from a presence server (140, 340) to a monitoring wireless communication device (130, 330), where the presence message indicates a location-oriented status of a monitored wireless communication device (120, 320-322). The communication system (110, 310) receives the presence message from the presence server (140, 340) and determines if the monitoring wireless communication device (130, 330) is in an active mode. If the monitoring wireless communication device (130, 330) is in the active mode, the presence message is transferred for delivery to the monitoring wireless communication device (130, 330). If the monitoring wireless communication device (130, 330) is not in the active mode, filtering characteristics are applied to the presence message, summary data of the presence message is created, and the summary data of the presence message is transferred for delivery to the monitoring wireless communication device (130, 330) once the monitoring wireless communication device (130, 330) enters the active mode.</p> |
