Apparatus and method for recording cellular call in an internet telephone system

Abstract

Call recording in an Internet telephone system is provided. A dual-mode terminal includes a call server interworker for, when a cellular call commences, determining whether it is possible to access a call server which controls Voice over Internet Protocol (VoIP) calls; a recording interface processor for, when it is possible to access the call server, setting a connection to a recording server; a recorder for generating recording data packets comprising a cellular phone conversation; and a data communicator for transmitting the recording data packets to the recording server.

1 . An apparatus in a dual-mode terminal in an Internet telephone system, the apparatus comprising:
 a call server interworker for, when a cellular call commences, determining whether it is possible to access a call server which controls Voice over Internet Protocol (VoIP) calls;   a recording interface processor for, when it is possible to access the call server, setting a connection to a recording server;   a recorder for generating recording data packets comprising a cellular phone conversation; and   a data communicator for transmitting the recording data packets to the recording server.   
     
     
         2 . The apparatus of  claim 1 , wherein the call server interworker activates the data communicator when the cellular call commences, and determines whether the dual-mode terminal is a subscriber of the call server. 
     
     
         3 . The apparatus of  claim 2 , wherein the data communicator buffers data packets comprising the cellular phone conversation while determining whether the dual-mode terminal is the subscriber of the call server. 
     
     
         4 . The apparatus of  claim 1 , wherein, when a connection status index indicative of a connection status to the recording server falls below a threshold, the recorder buffers generated recording data packets, and
 when the connection status index is greater than or equal to the threshold, the data communicator transmits the buffered recording data packets to the recording server.   
     
     
         5 . An apparatus in a recording server in an Internet telephone system, the apparatus comprising:
 a processor for, when recording of a cellular call is requested from a dual-mode terminal having a cellular telephone function, setting a connection to the dual-mode terminal; and   a recording DataBase (DB) for storing recording data packets which comprises a cellular phone conversation stored from the dual-mode terminal.   
     
     
         6 . The apparatus of  claim 5 , wherein the recording DB indexes the recording data of the cellular call according to at least one of a transmission type, a transmission length, an authentication number, a sender number, a recipient number, an extension number, packet order, and a call duration. 
     
     
         7 . A method for operation of a dual-mode terminal in an Internet telephone system, the method comprising:
 when a cellular call commences, determining whether it is possible to access a call server which controls Voice over Internet Protocol (VoIP) calls;   when it is possible to access the call server, setting a connection to a recording server;   generating recording data packets comprising a cellular phone conversation; and   transmitting the recording data packets to the recording server.   
     
     
         8 . The method of  claim 7 , further comprising:
 when it is possible to access the call server, activating a data communicator when the cellular call commences and determining whether the dual-mode terminal is a subscriber of the call server.   
     
     
         9 . The method of  claim 8 , further comprising:
 determining whether the dual-mode terminal is the subscriber of the call server, and buffering data packets comprising the cellular phone conversation.   
     
     
         10 . The method of  claim 7 , further comprising:
 when a connection status index indicative of a connection status to the recording server falls below a threshold, buffering generated recording data packets; and   when the connection status index is greater than or equal to the connection status index, transmitting the buffered recording data packets to the recording server.   
     
     
         11 . A method for operation of a recording server in an Internet telephone system, the method comprising:
 when recording of a cellular call is requested from a dual-mode terminal having a cellular telephone function, setting a connection to the dual-mode terminal; and   storing recording data packets which comprises a cellular phone conversation stored from the dual-mode terminal.   
     
     
         12 . The method of  claim 11 , further comprising:
 indexing the recording data of the cellular call according to at least one of a transmission type, a transmission length, an authentication number, a sender number, a recipient number, an extension number, packet order, and a call duration.
