7 is a diagram illustrating a flow of connection to the Internet using a software SIM according to an embodiment of the present invention.

As shown in FIG. 7, as the user executes the virtual phone application 211, an interface such as an Internet window may be provided on the screen of the calling mobile terminal 510 so that the virtual phone can be used. Enter the address of the desired web site (S610). In this case, the website address may include a domain name and an IP address.

The virtual phone application 211 transmits a data service request including a web site address input from a user to the virtual phone device 100. At this time, the virtual phone application 211 transmits the data service request including the identification information of the virtual phone application 211 and the user's additional subscriber unique identification number together with the web site address (S620).

Receiving the data service request, the virtual phone device 100 specifies a software SIM by using the user's additional subscriber unique identification number included in the data service request, and the virtual phone application 211 retrieved from the software SIM. The user is authenticated by checking whether the identification information matches the identification information of the virtual phone application 211 included in the data service request (S630). Here, it is described that the user is authenticated using the identification information of the virtual phone application 211, but the user may be authenticated using information of a hardware sim (eg, IMSI) according to an embodiment.

If authentication is successful, the virtual phone device 100 attempts mutual authentication by transmitting the user's additional subscriber unique identification number and the additional network authentication key to the mobile network (S640). And when the mutual authentication between the virtual phone device 100 and the mobile network is completed, the virtual phone device 100 selects one IP address from the IP address pool, sets the source IP address as the selected IP address, and sets the destination IP address. A data connection request packet in which the address is set as the web site address is transmitted to a packet network (PDN-GW) (S650). A plurality of IP addresses are stored in the IP address pool, and the virtual phone device 100 selects an IP address from the IP address pool so as not to be duplicated for each user.

The virtual phone device 100 correspondingly stores the user's additional phone number or additional subscriber unique identification number and the source IP address (ie, the IP address selected from the IP address pool), so that the source IP address from the website address When a packet recorded with the destination IP address is received, the user is identified using the destination IP address, and the packet is transmitted to the user's portable terminal to connect the Internet (S660).

When the data service is completed, the virtual phone device 100 may delete the source IP address stored in correspondence with the user's additional phone number or the additional subscriber's unique identification number. That is, the IP address allocated to the user can be retrieved and stored again in the IP address pool. Alternatively, the virtual phone device 100 may maintain the IP address allocated to the user until the two-phone service is terminated.

According to the above, it is possible to use two phone numbers in one terminal by implementing a SIM in a virtual space as software, and it is possible to minimize the cost of manufacturing and purchasing SIMs according to the opening of a new phone number. .

In addition, even when the terminal is lost, the function of the SIM can be immediately blocked in the system in which the software SIM is stored, thereby minimizing the risk of personal information leakage.
