Abstract: A personal emulating device of the present invention for emulating global phone communication as domestic mobile communication according to the present invention comprises a Universal Subscriber Identity Module (USIM) authentication unit, an information confirmation unit, an authentication processing unit, and a linking unit. The USIM authentication unit includes: a USIM interface unit which interfaces with a USIM of a designated standard; an antenna unit which transmits and receives radio frequency signals of a designated mobile communication standard to and from a base station in a mobile communication network corresponding to the USIM interfaced with the USIM interface unit; a radio unit which performs a signal processing operation for transmitting and receiving the radio frequency signals of the designated mobile communication standard to and from the base station in the mobile communication network corresponding to the USIM interfaced with the USIM interface unit; a mobile communication processing unit which performs a mobile communication operation procedure equivalent to a mobile communication operation of a mobile communication terminal that interfaces with the USIM interfaced with the USIM interface unit; and a communication unit which connects to the internet via a designated internet connection device, wherein the USIM authentication unit authenticates whether a valid USIM issued validly through a designated mobile communication company interfaces with the USIM interface unit. If the valid USIM is interfaced with the USIM interface unit, the information confirmation unit confirms identification information including a mobile phone number stored in a designated storage area of the USIM interfaced with the USIM interface unit. The authentication processing unit provides the mobile phone number of the USIM (or identification information including the mobile phone number) to a designated authentication server by means of the communication unit to request authentication of whether the mobile phone number of the USIM is mapped and registered to valid unique identification information, and receives an authentication result, authenticating the mapping state of the valid unique identification information and the mobile phone number of the USIM, from the authentication server. When the mapping and registration state of the valid unique identification information and the mobile phone number of the USIM is authenticated, the linking unit links a designated Session initiation Protocol (SIP) operation, performed by associating an SIP function of a program of the user radio terminal corresponding to the authenticated unique identification information with the SIP processing function of the designated communication server, or links a designated mobile communication operation, performed through the mobile communication processing unit, with a designated SIP operation performed by associating an SIP function of the program of the user radio terminal, corresponding to the authenticated unique identification information, with an SIP processing function of the designated communication server.
