1. A method of displaying a map on a mobile terminal, comprising the steps of:
- a) estimating a global position of said mobile terminal from signals transmitted from a plurality of GPS (global positioning system) satellites and received by said mobile terminal, b) determining a degree of precision of the estimated global position of said mobile terminal;
c) determining a size of an area to be displayed according to said degree of precision;
d) generating a map of said area of said determined size according to said global position of said mobile terminal; and
e) displaying said map on said mobile terminal.

Abstract
The global position of a mobile terminal is estimated from GPS (global positioning system) signals transmitted from a number of GPS satellites and received by the mobile terminal. The degree of precision of the estimated global position is determined and the size, or scale of an area to be displayed is determined according to the degree of precision, and a map of the area of the determined size is generated according to the global position of the mobile terminal, and displayed on the mobile terminal.

8. A mobile communication system comprising:
-
a communications network;
a server connected to the network for determining a global position from received GPS (global positioning system) signals; and
a mobile terminal for receiving GPS signals from GPS satellites and transmitting the received GCS signals to said server station via said communications network to thereby cause said server station to estimate the global position of the mobile terminal, said server determining a degree of precision of the estimated global position of said mobile terminal and determining the size of an area to be displayed on said mobile terminal according to said degree of precision, generating a map of said area of said determined size according to said global position of said mobile terminal and communicating the generated map to said mobile terminal. - View Dependent Claims (9, 10, 11, 12, 14, 15, 16)
