Abstract

The prevent invention is to provide a method of determining a PHS mobile phone user'"'"'s exact position, which comprises the steps of establishing a positioning database containing a plurality of CS (cell station) numbers and position information associated with the CS numbers respectively in the mobile phone; entering into a position inquiry mode of the positioning database chosen by the PHS mobile phone user; searching for a corresponding CS number in the positioning database based on a current CS number detected by the PHS mobile phone; and showing the position information associated with the current CS number on a display of the mobile phone when the corresponding CS number exists in the positioning database, so as to enable the user to determine a precise location by making a position inquiry through the mobile phone without having to pay any additional fee to PHS service provider.

Claims

1. A method of determining a PHS mobile phone user'"'"'s exact position comprising the steps of:

establishing a positioning database containing a plurality of CS (cell station) numbers and position information associated with the CS numbers respectively in the PHS mobile phone;

entering into a position inquiry mode of the positioning database chosen by the PHS mobile phone user;

searching for a corresponding CS number in the positioning database based on a current CS number detected by the PHS mobile phone; and

showing the position information associated with the current CS number on a display of the PHS mobile phone when the corresponding CS number exists in the positioning database.

2. The method of claim 1, wherein in response to receiving the position inquiry mode of the positioning database chosen by the PHS mobile phone user the method further comprises the steps of:

entering into a positioning information mode of a function menu comprising a submenu including an exact position inquiry option and a supplementary database option;

searching for the corresponding CS number in the positioning database in response to the exact position inquiry option chosen by the PHS mobile phone user and reading the position information associated with the corresponding CS number; and

showing the position information associated with the corresponding CS number on the display of the PHS mobile phone, when the position information associated with the corresponding CS number has already been established in the positioning database.

3. The method of claim 2, wherein when the position information corresponding to the current CS number hasn'"'"'t been established in the positioning database, the method further comprises the step of permitting the PHS mobile phone user to input and edit a corresponding CS number and position information associated with the corresponding CS number to the positioning database in response to the supplementary database option chosen by the PHS mobile phone user.

4. The method of claim 1, wherein in response to the position inquiry mode of the positioning database chosen by the PHS mobile phone user for determining an exact position, the method further comprises the steps of:

entering into a standby mode and receiving the position inquiry mode of the positioning database chosen by the PHS mobile phone user through pressing a shortcut key;

when the position information associated with the corresponding CS number has already been established in the positioning database, showing the position information on the display of the PHS mobile phone.

5. The method of claim 4, wherein when the position information corresponding to the current CS number hasn'"'"'t been established in the positioning database, the method further comprises the step of showing the current CS number on the display of the PHS mobile phone.

6. The method of claim 1, wherein in response to a request of obtaining the PHS mobile phone user'"'"'s exact position from a calling person, the method further comprises the steps of:

receiving a short message about position inquiry of the PHS mobile phone user from the calling person, the message comprising a password;

determining whether the password in the short message is correct or not;

when the password in the short message is correct, searching for an exact position of the PHS mobile phone immediately; and

transmitting the exact position to the calling person.

7. The method of claim 6, wherein when the password in the short message isn'"'"'t correct, the method further comprises disabling the PHS mobile phone to get any related information and maintaining the PHS mobile phone in its standby mode.
