Method and apparatus of transmitting personal information in subscriber-based ringback tone service

A method for transmitting personal information in a subscriber-based ringback tone service comprising:

• a call-originating exchanger requesting location information to a home register when a calling terminal requests a call to a called terminal;
• a home location register requesting routing information of the called terminal to a call-terminating exchanger and providing the call-terminating exchanger with the routing information, first information and second information from the call-terminating exchanger if the request for the location information of the called terminal is received, wherein the first information concerns about whether a ringback tone correspondingly set in the called terminal is to be replaced and the second information is for routing to a sound providing means;
• the call-originating exchanger requesting a call connection to the sound providing means based on the first and the second information;
• and
• the sound providing means call-connecting to the calling terminal, detecting a specific sound which is correspondingly set to the called terminal to provide the calling terminal with the detected specific sound if the request for the call connection is received,
• wherein the specific sound is generated by combining a personal information sound for specific information, which identifies a called subscriber or represents a character of the called subscriber, with the ringback tone including at least one replacement sound which is set by the called subscriber, wherein the combination includes specific information between two of the at least one replacement sounds.

An apparatus for transmitting personal information in a subscriber-based ringback tone service comprising:

• a home location register for providing first information about whether or not a ringback tone set in a profile of a called terminal of a call-terminating exchanger is replaced and second information for routing to sound providing means when the called terminal is registered in the call-terminating exchanger;
• the call-terminating exchanger for requesting a call connection to the sound providing means based on the first and the second information if a request for a call to the called terminal is received;
• and
• the sound providing means for call connecting with a calling terminal, detecting a specific sound which is correspondingly set to the calling terminal to provide the calling terminal with the detected specific sound if the request for the call connection is received from the call-terminating exchanger, wherein the specific sound is generated by combining a personal information sound for specific information with a common ringback tone including at least one replacement sound which is set by a called, subscriber wherein the combination includes specific information between two of the at least one replacement sounds.
