Benefits of technology

"The present invention provides a method for displaying the location of a cellular phone caller through a short message service (SMS) and allowing the answerer to see the caller's position on the screen. This helps to improve safety and tracking capabilities. The method is suitable for any cellular phone with SMS function and does not require any additional development costs."

Problems solved by technology

The location of a caller can not be known from the screen so that the requirement of tracking and safety cannot be attained.

Embodiment Construction

[0012]First of all, please refer to FIG. 1. FIG. 1 shows a cellular network system structure having a positioning function and a position coordinate database according to the present invention. From FIG. 1, when a cellular phone caller B makes a phone call to a cellular phone answerer A, the call goes to a cellular phone base station 2 via a cellular phone net 1 first. The base station 2 checks whether the cellular phone caller B has started the function for informing the location of a caller to a phone answerer. If so, the base station 2 starts to calculate position coordinates of the caller by using a positioning technology (for example, Global Positioning System (GPS), three points positioning technology or base station positioning technology, etc.). Then, the base station 2 compares the calculated position coordinates of the caller with a location data stored in a position coordinate database to determine the location on a map. Thereafter, the base station 2 sends a short messag...

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).

Description

FIELD OF THE INVENTION [0001]The present invention relates to a method for displaying the location of a cellular phone caller, particular to a method for displaying location of cellular phone caller by using an “Unstructured Supplementary Service Data” function in the GSM to display the caller's address in the answerer's phone by a Class 0 short message (SMS).BACKGROUND OF THE INVENTION[0002]Till now, cellular phone only display a caller's name and phone number on the display screen of a cellular phone. The location of a caller can not be known from the screen so that the requirement of tracking and safety cannot be attained.SUMMARY OF THE INVENTION[0003]The object of the present invention is to provide a method for displaying the location of a cellular phone caller, enabling the caller's positioned location to be transmitted to an answerer's cellular phone through a Class 0 short message (SMS) and to be displayed ton the display screen of the answerer's cellular phone in characters...
