A voice message is sent to the broker to input the pair of telephone numbers of the first and second subscribers and the virtual number validity period (step 303). The broker 151 inputs the pair of telephone numbers and the virtual number validity period of the first subscriber and the second subscriber to which the virtual number is to be assigned according to the message of the service 153 (step 305).

The pair of telephone numbers of the first subscriber and the second subscriber and the virtual number valid period to which the input virtual number is assigned are transmitted to the virtual number manager 133 through the service 153, and the virtual number manager 133 The telephone numbers and virtual number valid periods of the first and second subscribers are temporarily stored.

The virtual number manager 133 sets a virtual number corresponding to the input pair of subscriber telephone numbers and the telephone numbers of respective subscribers (step 307).

The virtual number set by the virtual number manager 133 is transmitted to the subscribers of the first and second subscriber stations 111 and 121 through the calling exchange station 117, the calling control station 115, and the calling base station 113, respectively. (Step 309). At this time, the transmission method uses a text message and a voice message service.

In an embodiment of the present invention, a process of setting the virtual number using an answering service has been described, but in another embodiment of the present invention, the process of setting the weather number is performed by a wireless application protocol (WAP) server of a mobile terminal (WAP). 163 may be set using the Internet network 173 and the World-Wide Web (WWW) server 175.

That is, as shown in Figure 5, the process of setting the virtual number by using the swap server 163, after moving to the virtual numbering site using the swap of the mobile terminal of the broker 161 is entered Enter a pair of telephone numbers of the first subscriber and the second subscriber and the virtual number validity period to which the virtual number is to be assigned, and a pair of the telephone numbers of the first subscriber and the second subscriber to which the virtual number is to be assigned and the virtual number. The number validity period is transmitted to the virtual number management unit 133 through the swap server 163. The virtual number manager 133, which has received the telephone number pair and the virtual number validity period of the first and second subscribers, generates a virtual number for each of the subscribers, and the virtual numbers are generated using a text message service. Transmit to the first subscriber and the second subscriber, respectively.

In addition, as shown in Figure 6, the process of setting the virtual number using the web server 175, the broker 171 is connected to the virtual number Internet site through the Internet network 173 virtual grant Internet According to the screen of the site, the pair of telephone numbers of the first subscriber and the second subscriber to which the virtual number is to be assigned and the virtual number validity period are entered, and the telephones of the first subscriber and the second subscriber to which the virtual number is to be assigned are entered. The pair of numbers and the virtual number validity period are transmitted by transmitting to the virtual number management unit 133 using the web server 175.
