Personal station and information providing system
First Claim
1. A personal station for performing a navigation operation, comprising:
- detecting means for detecting the location of the personal station corresponding to control carriers or communication carriers received from cell stations and cell station numbers designated thereto;
a memory for storing location information;
registering means for registering present location of a user of the personal station;
means for determining whether the location information obtained from said detecting means corresponds to a cell station number of a cell station most adjacent to the present location of the user, said determining means comprising means for comparing said location information obtained from said detecting means with a cell station number transmitted when a radio link is established with a cell station so as to determine any one of a direction in which the user is moving and a distance from the present location to a desired location; and
display means for displaying the present location corresponding to the location information.

Abstract
An object of the present invention is to provide a personal station (hereinafter referred to as PS) for use with a location information detecting system using a personal handyphone system (hereinafter referred to as PHS) for detecting the moving direction of the PS along with the location thereof. After the user initially registers the present location to the PS and inputs the address of the destination, the PS calculates the distance from the present location to the destination and displays the result. When the user moves, the PS detects the present location and moving direction thereof by a method using electric field intensities, angle with cell stations (hereinafter referred to as CSs), an atomic clock, and so forth. Thereafter, the PS determines whether or not the detected present location is correct. When the detected present location is correct, the PS calculates the distance from the present location to the destination and displays the result. When the user has arrived at the destination, the PS completes the entire flow.
