Abstract

A wireless terminal displays its location and navigation information (map segment) on its display. The wireless terminal accesses a Global Positioning System (GPS) receiver of the wireless terminal to determine its location coordinates. The wireless terminal determines a maximum data size for navigation information to be downloaded. The wireless terminal sends a navigation information download request to a map server via a supporting wireless network infrastructure that includes the location coordinates and the maximum data size. The wireless terminal receives navigation information that has a data size no greater than the maximum data size and displays the navigation information on the display. The wireless terminal may display a map segment and an icon representing the wireless terminal at a location corresponding to the location coordinates of the wireless terminal with respect to the map segment. The wireless terminal may download a premises map from a premises map server.

Claims

1. A method for operating a wireless terminal to display navigation information on a display of the wireless terminal, the method comprising:

accessing a Global Positioning System (GPS) receiver of the wireless terminal to determine location coordinates of the wireless terminal;

determining a maximum data size for a map segment download;

based upon user input, determining information regarding geographic features;

sending a map segment download request to a server via a supporting wireless network infrastructure, the map segment download request including the location coordinates, the maximum data size, and the information regarding geographic features;

receiving a map segment corresponding to the location coordinates, the maximum data size, and the information regarding geographic feature; and

displaying the map segment on the display.
