Downloading map segment(s) to a cell phone based upon its GPS coordinates and mobility
First Claim
1. A method for operating a map server to service a wireless terminal, the method comprising:
- receiving a map segment download request from the wireless terminal via at least a supporting wireless network infrastructure, the map segment download request including location coordinates of the wireless terminal and a maximum data size;
creating navigation information that contains a map segment and that corresponds to the maximum data size, the map segment having a level of resolution that is selected based upon the maximum data size; and
transmitting the navigation information to the wireless terminal via the at least one supporting wireless network infrastructure.

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.
