Abstract

The present invention relates to a method for displaying the location of a cellular phone caller. In the present method, a caller'"'"'s cellular phone transmits a short message preset by a cellular base station to the base station through an Unstructured Supplementary Service Data (USSD) function by using a cellular phone and selects to start or stop a function for informing the location of a caller to a phone answerer. When a phone call is made and the location informing function is stopped, the base station transmits no caller location information to an answerer'"'"'s cellular phone. If the location informing function is activated, the base station uses a positioning technology to calculate position coordinates of the caller. And then, the base station compares the position coordinates with a location data stored in a position coordinate data base of the base station and transforms the location to a closest address so as to display the caller'"'"'s address in the answerer'"'"'s phone by a Class 0 SMS (short message system).

Claims

1. A method for displaying the location of a cellular phone caller, used to display a caller'"'"'s location on the screen of a cellular phone when an incoming phone call comes in, said method comprising the following steps:

(1) a cellular phone user making a call;

(2) a base station calculating the position coordinates of said caller by using a positioning technology;

(3) said base station comparing said position coordinates with a location data stored in a position coordinates data base of said base station and transforming said location to a closest address; and

(4) said base station connecting said call and transmitting a Class 0 SMS (short message system) to an answerer'"'"'s cellular phone when the answerer'"'"'s cellular phone rings after said connection is completed.

2. The method according to claim 1, wherein, after step (1), if said caller'"'"'s cellular phone transmits a short message preset by a cellular base station to said base station through an Unstructured Supplementary Service Data (USSD) function to start said function for informing the location of a caller, said Class 0 SMS contains an address of said caller.

3. The method according to claim 1, wherein, after step (1), if said caller'"'"'s cellular phone transmits a short message preset by a cellular base station to said base station through an Unstructured Supplementary Service Data (USSD) function to stop said function for informing the location of a caller, said base station connects said call and transmits a Class 0 SMS (short message system) to an answerer'"'"'s cellular phone when said answerer'"'"'s cellular phone rings after said connection is completed.

4. The method according to claim 3, wherein the Class 0 SMS does not contain an address of the caller.

5. The method according to claim 1, wherein said positioning technology is Global Positioning System (GPS), three points positioning technology or base station positioning technology.

6. A method for displaying the location of a cellular phone caller, used to display a caller'"'"'s location on the screen of a cellular phone when the an incoming phone call comes in, said method comprising the following steps:

(1) said caller'"'"'s cellular phone transmitting a short message preset by a cellular base station to said base station through an Unstructured Supplementary Service Data (USSD) function to either start or stop a function for informing the location of a caller,

(2) the cellular phone user making a call;

if said function for informing the location of a caller is stopped, then skipping the following steps (3) and (4) and directly going to step (5);

(3) a base station calculating the position coordinates of said caller by using a positioning technology;

(4) the base station comparing said position coordinates with a location data stored in a position coordinate data base of said base station and transforming said location to a closest address; and

(5) the base station dials the call and transmits a Class 0 SMS (short message system) to an answerer'"'"'s cellular phone;

wherein if said function for informing the location of a caller is started, said short message contains said caller'"'"'s address; and

if said function for informing the location of a caller is stopped, said short message does not contain said call'"'"'s address

7. The method according to claim 6, wherein said positioning technology is Global Positioning System (GPS), three points positioning technology or base station positioning technology.
