CROSS-REFERENCE TO RELATED APPLICATIONS This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2001-239274, filed Aug. 7, 2001 and Japanese Patent Application No. 2002-197272, filed Jul. 5, 2002, the entire contents of which are incorporated herein by reference.
DETAILED DESCRIPTION OF THE INVENTION An embodiment of a target position search apparatus according to the present invention will now be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing an arrangement of the first embodiment.
As the first embodiment, it will be described a navigation service system using a portable terminal (hereinafter referred to �CDMA terminal�) of a CDMA (Code Division Multiple Access) method, which is a kind of portable telephones, equipped with a GPS (Global Positioning System) function.
The key input device 31 has dial (numeric) keys combined with character input keys, a �speaking� key, an �off� key, a redial key, a mode select key, a cursor key and a shutter key, its operation signal is inputted directly to the control device 30.
When completion of the input is directed by operating the �speaking� key of the key input device 31, a calling process is performed by the inputted telephone number, the telephone number is transmitted to the service center apparatus, and a location of the terminal owned by the user of the called party is inquired (step A02).
At this point, the service center apparatus, which has received the telephone number of the called party, inquires a registered state of a present location of the CDMA terminal 10 of the telephone number, determinates by its reply whether or not the calling party 42 and the called party 43 exist within a communication area of the CDMA base station 41, in other words, determinates whether or not the calling party 42 and the called party 43 exist within a distance being able to perform an image display (step A03). In case that a result of the determination is �within communication area�, the service center apparatus connects and maintains a communication line between the CDMA terminal 10 of the calling party 42 and the CDMA terminal 10 of the called party 43.
In case that the result of the determination of the service center apparatus is �out of communication area�, the CDMA terminal 10 of the calling party 42 may be arranged to display only a received error message in a manner that the service center apparatus not only performs a process not to connect (disconnect) a communication line to the terminal of the called party 43, but also the service center apparatus transmits the error message to the CDMA terminal 10 of the calling party 42.
FIG. 5B illustrates a state that a position of the called party 43 stays within the screen of the display device 11. The ellipse E showing the position of the called party 43, �50 M� of the distance to the called party 43 and four arrows of four sides of the screen, which dare not to perform a special flashing or coloring because the called party 43 stays in the screen, are shown by superposing on an image taken by the camera device 12.
The second embodiment of the invention applicable to a navigation service system utilizing a portable terminal of a CDMA method, which is a kind of portable telephones, (hereinafter referred to �CDMA terminal�) equipped with a GPS function will be described referring to the accompanying drawings.
FIG. 9A illustrates an input screen shown in the display device 11 of the CDMA terminal 10 in step B01, following �Facility Guidance Service� of a service name and a guidance message suggesting input of a facility name, an input window is displayed for inputting actually the facility name.
When completion of input of a facility name is directed by operating a �speaking� key of the key input device 31, the CDMA terminal 10 performs a process calling the service center apparatus 52 and transmits data of the inputted facility name to the service center apparatus to inquire of the service center apparatus 52 about a location of the facility name (step B02).
FIG. 9B illustrates a state that a position of the facility stays within the screen of the display device 11. The ellipse E showing the position of the facility, �250 M� of the distance to the facility and four arrows of four sides of the screen, which do not perform a special flashing or coloring because the facility stays in the screen, are shown by superposing on an image taken by the camera device 12.
The third embodiment of the invention applicable to a navigation service system utilizing a portable terminal of a CDMA method, which is a kind of portable telephones, (hereinafter referred to �CDMA terminal�) equipped with a GPS function will be described referring to the accompanying drawings.
When completion of the input of the facility name is directed by operating the �speaking� key of the key input device 31, a calling process to the service center apparatus 52 is performed. The inputted data of the facility name are transmitted to the service center apparatus 52, thereby a location of the facility name is inquired of the service center apparatus (step C02).
In case that operation of an �off� key of the key input device 31 is detected in step C14 during repeat performance of the process of steps C07 to C13, the communication line between the service center apparatus 52 is disconnected (step C06) and the process is finished.
The service center apparatus 52 determinates whether or not the communication line is disconnected by operating the �off� key of the key input device 31 of the CDMA terminal 10 (step C30). When the communication line is connected, the process returns to step C26 and repeat the process of steps C26 to C30 till the communication line is disconnected.
The fourth embodiment of the invention applicable to a navigation service system utilizing a portable telephone (hereinafter referred to �PHS terminal�) corresponding to PHS (Personal Handyphone System: the second generation wireless telephone system) will be described referring to the accompanying drawings.
