Herein, it is described that the user is authenticated using the identification information of the virtual phone application 211, but the user can be authenticated using the hardware wake-up information (e.g., IMSI) according to the embodiment.

If the authentication is successful, the virtual phone apparatus 100 transmits the additional subscriber unique identification number and the additional network authentication key of the user to the mobile network to attempt mutual authentication (S640). When the mutual authentication between the virtual phone apparatus 100 and the mobile network is completed, the virtual phone apparatus 100 selects one IP address from the IP address pool, sets the source IP address to the selected IP address, The PDN-GW transmits a data connection request packet in which the address is set to the website address (S650). The IP address pool stores a plurality of IP addresses, and the virtual phone apparatus 100 selects an IP address from an IP address pool so that each user is not overlapped.

The virtual phone apparatus 100 stores the source IP address (i.e., the IP address selected from the IP address pool) in correspondence with the user's additional telephone number or additional subscriber unique identification number and the source IP address (Step S660). If the destination IP address of the packet is received from the destination IP address, the destination IP address is used to confirm the user and the packet is transmitted to the portable terminal of the user.

When the data service is completed, the virtual phone apparatus 100 may delete the stored source IP address corresponding to the user's additional telephone number or the additional subscriber unique identification number. That is, the IP address assigned to the user can be retrieved and stored in the IP address pool again. Alternatively, the virtual phone apparatus 100 may maintain the IP address assigned to the user until the telephone service is canceled.

According to the above description, it is possible to use two telephone numbers in one terminal by implementing the software in the virtual space, and it is possible to minimize the cost of manufacturing and purchasing the modem by opening a new telephone number .

In addition, when the terminal is lost, the function of the wisdom can be immediately blocked in the system in which the software wisdom is stored, so that the risk of leakage of personal information can be minimized.

While the specification contains many features, such features should not be construed as limiting the scope of the invention or the scope of the claims. In addition, the features described in the individual embodiments herein may be combined and implemented in a single embodiment. On the contrary, the various features described in the singular embodiments may be individually implemented in various embodiments or properly combined.

Although the operations are described in a particular order in the figures, it should be understood that such operations are performed in a particular order as shown, or that all described operations are performed in a series of sequential orders, or to obtain the desired result. In certain circumstances, multitasking and parallel processing may be advantageous. It should also be understood that the division of various system components in the above embodiments does not require such distinction in all embodiments. The above-described application components and systems can generally be packaged into a single software product or multiple software products.

The method of the present invention as described above can be implemented in an application and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.). Such a process can be easily carried out by those skilled in the art and will not be described in detail.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
