Downloading map segment(s) to a cell phone based upon its GPS coordinates and mobility
First Claim
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 navigation information download;
sending a navigation information download request to a server via a supporting wireless network infrastructure, the navigation information download request including the location coordinates and the maximum data size;
receiving navigation information corresponding to the location coordinates of the wireless terminal, the navigation information having a data size no greater than the maximum data size; and
displaying the navigation information on the display to indicate the manner in which the wireless terminal may reach a desired destination.

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.
