发明名称 Mobile tracking
摘要 A method of tracking a first wireless communications device using another computing device, such as a second wireless communications device, includes obtaining current position data for the first wireless communications device and obtaining one or more of speed data, time data, and path data for the first wireless communications device. The first wireless device then transmits the current position data and at least one of the speed data, time data and path data to the second wireless communications device or other computing device. In addition to current position data, the speed, path and time data facilitate tracking of the first wireless communications device. When a first mobile user wants a second mobile user to follow him, the first mobile user can put his device in "follow me" (tracking) mode. This is particularly useful when the first and second mobile users are traveling in respective cars or other vehicles.
