CALL VOICE CHARACTER CONVERSION SERVICE METHOD IN A MOBILE COMMUNICATION NETWORK, SPECIALLY WITH REGARDS TO CONVERTING VOICE CALL CONTENTS BETWEEN AN ORIGINATOR AND A RECEIVER INTO CHARACTERS TO SUPPLY AS A TEST MESSAGE

摘要

PURPOSE: A call voice character conversion service method in a mobile communication network is provided to convert voice call contents between mobile communication terminals into characters, and to supply the characters as a text message, so that a receiver can exactly receive the voice call contents without storing a voice. CONSTITUTION: An originating terminal and a receiving terminal perform a voice call through a call connection via MSCs(S10). If either the originating or the receiving terminal requests a call voice character conversion service(S11), a character conversion processing server responds to the service request(S12). The server requests a speech voice to be delivered(S13). Each MSC supplies a call voice signal to the server(S14). A voice recognition processing module of the server processes transmitting/receiving voice signals, and generates voice recognition code data(S15). A character conversion module converts the voice recognition code data into character data(S16). A text message generation module of the server generates the character data in text message type to store a text message(S17), and supplies the text message with a mobile phone number to an SMC(Short Message Center)(S18). The SMC converts the text message in short message type, and transmits the message to the corresponding terminal(S19).
