1. A terminal unit comprising:
- detection means for detecting at said terminal unit a signal to be used for determination of a present position of said terminal unit, said signal being demodulated from a multiplexed received signal;
transmission means for transmitting said signal as detected by said detection means without performing position determination processing on said detected signal at said terminal unit, to an external processing unit positioned apart from said terminal unit to determine the present position of said terminal unit;
reception means for receiving position information at said terminal unit on the present position of said terminal unit, determined in said external processing unit; and
output means for combining said position information said reception means receives, by indicating the position information superimposed on map information and for outputting the combination result.

Abstract
A radiocommunication system including a portable terminal, a base station and a server. The portable terminal transmits a destination to the server and further sends the ID number (CD_ID) of the base station coupled through a radio link to the portable terminal. The server has a table representative of a corresponding relationship between the ID number of the base station and the standing position of the base station and retrieves the position corresponding to the ID number thereof as the present position of the portable terminal from the table. Further, the server transmits map data corresponding to the present position of the portable terminal to the portable terminal.

17. A terminal unit comprising:
-
detection means for detecting a signal at a terminal unit to be used for determining a present position of said terminal unit, said signal being demodulated from a multiplexed received signal;
input means for inputting destination information;
transmission means for transmitting the present position determining signal detected by said detection means and said destination information inputted through said input means, without performing position determining processing on said detected signal at said terminal unit, to an external processing unit which determines present position information and destination position information;
reception means for receiving said present position information at said terminal unit and said destination position information determined in said external processing unit; and
output means for combining said present position information and said destination position information received by said reception means by superimposing said present position information and said destination position information on map information and for outputting the combination result. - View Dependent Claims (18, 19)
