First Claim
1. A method, comprising:
- detecting a phone call from a caller'"'"'s cellular phone to an answerer'"'"'s cellular phone;
receiving a short message having an instruction from the caller'"'"'s phone at a cellular base station through an Unstructured Supplementary Service Data (USSD) function, wherein the instruction is to (a) transmit a location of the caller'"'"'s phone to the answerer'"'"'s phone, or (b) not transmit the location of the caller'"'"'s phone to the answerer'"'"'s phone;
if the instruction is to transmit the location of the caller'"'"'s phone to the answerer'"'"'s phonecalculating position coordinates of the caller'"'"'s phone using a positioning technology;
comparing the position coordinates with location data stored in a position coordinates data base and transforming the position coordinates to an address; and
connecting the phone call and transmitting a Class 0 SMS (short message system) to the answerer'"'"'s cellular phone with the address of the caller'"'"'s cellular phone during the phone call;

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).

8. A method, comprising:
-
receiving a short message from a caller'"'"'s phone to a cellular base station through an Unstructured Supplementary Service Data (USSD) function to either enable or disable a function for providing a location of the caller to the answerer; detecting a phone call from the caller'"'"'s phone; and connecting the phone call and transmitting a Class 0 SMS (short message system) to an answerer'"'"'s cellular phone during the phone call, wherein if the function for providing the location of the caller is disabled, the base station connects the phone call and transmits a Class 0 SMS to the answerer'"'"'s cellular phone without an address of the caller'"'"'s phone; and if the function for providing the location of the caller is enabled, (a) calculating the position coordinates of the caller'"'"'s phone using positioning technology and (b) comparing the position coordinates with location data stored in a position coordinate data base of the base station and transforming the location to a caller'"'"'s address, and wherein the base station connects the phone call and transmits a Class 0 SMS to the answerer'"'"'s cellular phone that contains the caller'"'"'s address. - View Dependent Claims (9, 10, 11)
