System and method for providing a dial tone and a ring tone

Abstract

Provided is a system for providing a dial tone and a ring tone to a receiver terminal having one or more virtual numbers. A ring tone setting unit sets a ring tone corresponding to each of the one or more virtual numbers. An alarm sound providing server includes a controller configured to output, to the receiver terminal, a ring tone set for a corresponding virtual number according to the corresponding virtual number of the receiver terminal included in a call connection request signal transmitted from a caller terminal.

What is claimed is: 
     
         1 . A system for providing a dial tone and a ring tone to a receiver terminal having one or more virtual numbers, the system comprising:
 an alarm sound providing server that comprises a ring tone setting unit configured to set a ring tone corresponding to each of the one or more virtual numbers, and a controller configured to output a ring tone set for a corresponding virtual number to the receiver terminal according to the corresponding virtual number of the receiver terminal included in a call connection request signal transmitted from a caller terminal.   
     
     
         2 . The system of  claim 1 , wherein the alarm sound providing server further comprises a virtual number generation unit configured to generate the one or more virtual numbers on the receiver terminal. 
     
     
         3 . The system of  claim 1 , wherein the alarm sound providing server further comprises a location information extraction unit configured to extract location information of the caller terminal, and
 the ring tone setting unit is configured to set a ring tone according to the location information of the caller terminal extracted by the location information extraction unit, and   the controller is configured to output the ring tone according to the location information additionally to the ring tone set for the corresponding virtual number.   
     
     
         4 . The system of  claim 1 , wherein the alarm sound providing server further comprises a dial tone setting unit configured to set a dial tone corresponding to each of the one or more virtual numbers, and
 the controller is configured to output, to the caller terminal, a dial tone set for a corresponding virtual number according to the corresponding virtual number of the receiver terminal included in the call connection request signal.   
     
     
         5 . The system of  claim 1 , further comprising:
 a service connection server configured to determine whether the one or more virtual numbers of the receiver terminal is a number subscribed to a dial tone and ring tone providing service.   
     
     
         6 . The system of  claim 1 , wherein the alarm sound providing server further comprises a database configured to store information including a frequency of receiving a call connection request or a time of receiving the call connection request for each of the one or more virtual numbers. 
     
     
         7 . A method of providing a dial tone and a ring tone to a receiver terminal having one or more virtual numbers, the method comprising:
 setting a ring tone corresponding to each of the one or more virtual numbers; and   outputting, to the receiver terminal, a ring tone set for a corresponding virtual number according to the corresponding virtual number of the receiver terminal included in a call connection request signal transmitted from a caller terminal.   
     
     
         8 . The method of  claim 7 , further comprising:
 generating the one or more virtual numbers on the receiver terminal.   
     
     
         9 . The method of  claim 7 , further comprising:
 extracting location information of the caller terminal, wherein the setting the ring tone comprises:   setting a ring tone according to the extracted location information of the caller terminal, and wherein the outputting the ring tone comprises:   outputting the ring tone according to the location information additionally to the ring tone set for the corresponding virtual number.   
     
     
         10 . The method of  claim 7 , further comprising:
 setting a dial tone corresponding to each of the one or more virtual numbers, and   outputting, to the caller terminal, a dial tone set for a corresponding virtual number according to the corresponding virtual number of the receiver terminal included in the call connection request signal.   
     
     
         11 . The method of  claim 7 , further comprising:
 determining whether the one or more virtual numbers of the receiver terminal is a number subscribed to a dial tone and ring tone providing service.   
     
     
         12 . The method of  claim 7 , further comprising:
 storing information including a frequency of receiving a call connection request or a time of receiving the call connection request for each of the one or more virtual numbers.
