USING SMS AND TAGGED MESSAGE TO SEND POSITION AND TRAVEL INFORMATION TO SERVER AND/OR PEERS

摘要

The GPS position or other short information related to a wireless telephone (12, 50) is encapsulated in a tagged protocol such as XML and sent using short message service (SMS) to peers (12) or Internet servers (14), which can parse the tagged messages and extract, e.g., position information for display on a map.
