In addition, additional information other than those exemplified in Table 1 may be included in the information on the call forwarding service subscription information for other regions.

The virtual area code is a number opened by subscribing to a communication service of a communication service provider operating the communication company server 100 . The call forwarding number does not need to be subscribed to the communication service of the communication service provider operating the communication company server 100 .

When a call connection request for a virtual area code subscribed to a call forwarding service is received from the caller terminal 20 from the caller terminal 20, the communication company server 100 returns to the receiver terminal 30 corresponding to the call forwarding number of the virtual area code. A corresponding call connection request can be forwarded to be called.

The communication company server 100 may deliver the other area guide information including the virtual area code, call forwarding number, and area information requested for call connection from the caller terminal 20 to the app server 200 .

For example, when a call connection request for virtual area code '070-1234-5671' is received in a state in which the call forwarding service subscription information for other areas as shown in Table 1 is registered, the telecommunication company server 100 transmits the virtual area code '070' -1234-5671', call forwarding number '010-5678-1234', and local information 'Gangnam Seoul' may be transmitted to the app server 200. In addition, the guide information for other areas delivered to the app server 200 may include a phone number of the caller terminal 20 .

The app server 200 may deliver the guide information of other regions delivered from the communication company server 100 to the receiver terminal 30 . For example, the other area guide information may be delivered to the recipient terminal 30 corresponding to the call forwarding number '010-5678-1234' included in the guide information from the other area delivered from the communication company server 100 .

There may be two methods below for transmitting guide information for other regions from the app server 200 to the receiver terminal 30 . In the first method, if there is a request from a guide app installed in another area in the recipient terminal 30 that has received the call connection request, the app server 200 provides guide information in other areas to the recipient terminal 30 in response thereto. . The second method is that the app server 200 receives from the communication company server 100 and transmits other region guide information to the receiver terminal 30 as a push message.

The recipient terminal 30 may display other area guide information delivered from the app server 200 on the incoming screen.

2 and 3 illustrate an incoming call screen including guide information for other areas according to the present invention.

As illustrated in FIG. 2 , the other area guide app displays local information 'Seoul Gangnam', virtual area code '070-1234-5671' and outgoing phone number '010-1234-5678' on the incoming screen of the recipient terminal 30. can be displayed. Accordingly, the user of the receiver terminal 30 can know in which region the call is made to the virtual area code exposed, and respond accordingly.

On the other hand, as illustrated in FIG. 3 , when the caller information corresponding to the phone number of the caller terminal is included in the phone book of the receiver terminal 30 , the guide app for other regions may also display the caller information on the incoming screen. 3 shows an example in which caller information 'Gildong Hong' corresponding to the phone number '010-1234-5678' of the caller terminal is displayed.

Meanwhile, the communication company server 100 may include a voice signal corresponding to the area information specified in the virtual area code in the call connection request transmitted to the receiver terminal 30 . In this case, the voice signal corresponding to the area information may be output from the receiver terminal 30 before the call connection between the receiver terminal 30 and the caller terminal 20 .

Then, in step S420, the virtual area code requested for call connection is inquired from the other area guidance call forwarding service subscription information DB, and if the user is subscribed to the other area guidance call forwarding service, the telecommunication company server 100 provides the virtual area code and call forwarding service. Other area guide information including number and area information may be transmitted to the app server 200 (S440).

In step S430 , the communication company server 100 may include a voice signal corresponding to the area information specified in the virtual area code in the call connection request transmitted to the receiver terminal 30 . In addition, the guide information of other regions delivered to the app server 200 in step S430 may include the phone number of the caller terminal 20 .

The app server 200 may receive and store the guide information of other regions delivered in step S440 (S450).

Next, when the call connection request is received from the receiver terminal 30 , the guide app for other areas installed in the receiver terminal 30 may request guide information for other areas from the app server 200 ( S460 ).

Then, the app server 200 may provide the other area guide information stored in step S450 to the receiver terminal 30 (S470).

Thereafter, the guide app for other areas may display the guide information for other areas provided in step S470 on the incoming screen of the receiver terminal 30 (S480). When the caller information corresponding to the phone number of the caller terminal is included in the phone book of the receiver terminal 30, the other region guide app may also display the caller information on the call screen in step S480.
