In one embodiment, the social media app provides a service that integrates all functions of a communication app such as KakaoTalk, Band, and Facebook into one app, and in addition to this, provides an inbound two-way phone service. In addition, the same service app 110 as the sender terminal 100 may or may not be installed in the receiver terminal 200 .

The server system 300 may be configured to include one or more servers, and serves to connect a call between the caller terminal 100 and the receiver terminal 200 . The server system 300 may perform data communication through the caller terminal 100 and the data communication network 10, and voice communication through the caller terminal 100 and the receiver terminal 200 and the public switched telephone network 20. can Such a server system 300 transmits a call to the called terminal 200 to which the calling terminal 100 wants to make a call connection when an inbound call is received from the calling terminal 100, and the calling terminal 100 and By connecting the established call path and the called terminal 200 and the formed call path, a telephone connection is made between the calling terminal 100 and the called terminal 200 . For reference, the server system 300 may be referred to as a 'telephone connection server'.

2 is a block diagram of a server system according to an embodiment. As shown in FIG. 2 , the server system may include a phone request reception unit 310 , a table creation unit 320 , a number transmission unit 330 , and a phone connection unit 340 , and a table deletion unit 350 . may include more. For example, all of these may be implemented as software functional configurations executed by one or more processors. The call request reception unit 310 receives a call connection request from the service app 110 of the caller terminal 100 through the data communication network 10 with the receiver terminal 200 . When a call connection request is received, the table generating unit 320 creates a mapping table in which a caller's phone number, a recipient's phone number, and an outgoing phone number and a receiving phone number are mapped. Here, the caller phone number is a phone number of the caller terminal 100 , and the receiver phone number is a phone number of the receiver terminal 200 . In addition, both the calling phone number and the receiving phone number are phone numbers of the server system 300 .

In one embodiment, the service app 110 of the caller terminal 100 transmits the caller's phone number and the receiver's phone number together when a call connection request is made. Receive the number and the recipient's phone number. In another embodiment, at least one of the calling party phone number and the called party phone number is obtained from an internal database of the server system 300 . In this case, only identification information capable of identifying the sender and/or the receiver is received from the service app 110 of the caller terminal 100 , and the call request reception unit 310 has the received identification information and the server system 300 ) to obtain the corresponding phone number by searching the internal database. And the table generation unit 320 creates a mapping table in which the outgoing phone number and the incoming phone number provided from the call request reception unit 310 and the outgoing phone number and the incoming phone number of the server system 300 are mapped, It is stored in the table storage unit (360).

A mapping table is illustrated in FIG. 3 . The caller's phone number is 010-1111-1111, the recipient's phone number is 010-2222-2222, the outgoing phone number is 02-1588-9999, and the incoming phone number is 080-5555-5555. The outgoing phone number may be a representative phone number of the server system 300 , and the receiving phone number may be randomly selected from among a plurality of incoming phone numbers possessed by the server system 300 . That is, the table generating unit 320 may randomly select one unused reception phone number from among a plurality of reception phone numbers when generating the mapping table.

The number transfer unit 330 transmits a receiving phone number from among the phone numbers of the mapping table generated by the table generation unit 320 to the service app 110 of the caller terminal 100 through the data communication network 10 . . Accordingly, the service app 110 of the caller terminal 100 receives a phone number for reception through the data communication network 10 . The service app 110 that receives the incoming phone number automatically performs a call originating, and sets the caller phone number (010-1111-1111) and the incoming phone number (080-5555-5555) respectively to the caller number and After designation as a receiving number, a call is transmitted to the server system 300 through the public switched telephone network 20 . That is, the caller terminal 100 does not make a call to the receiver terminal 200 , but makes a call to the server system 300 . In an embodiment, the service app 110 of the caller terminal 100 automatically performs a call outgoing in the background when a receiving phone number is received.

When a call is received from the caller terminal 100 through the public switched telephone network 20, the telephone connection unit 340 searches the mapping table with the calling number and the receiving number of the incoming call. That is, the phone connection unit 340 searches for a mapping table including the calling party number and the receiving phone number matching the calling number and the receiving number of the incoming call. Through this, a mapping table as illustrated in FIG. 2 is searched. The telephone connection unit 340 designates an outgoing phone number (02-1588-9999) and a recipient phone number (010-2222-2222) included in the searched mapping table as the calling number and the receiving number, respectively, to the public switched telephone network (20) A call is transmitted to the receiver terminal 200 through That is, the server system 300 makes a direct call to the receiver terminal 200 . In addition, in response to an incoming call from the caller terminal 100 separately from the call outgoing to the receiver terminal 200, the phone connection unit 340 forms a call path, which is a call path between the server system 300 and the caller terminal 100. do.

The phone connection unit 340 responds to the called terminal 200 after sending a call to the called terminal 200 to form a called party communication path that is a communication path between the server system 300 and the called terminal 200, that is, the phone connection is made. A voice notification message including caller information of the caller terminal 100 is generated and transmitted to the ground receiver terminal 200 . An example of a voice alert message is, “The caller is the delivery man. If you want to make a call, press 1, otherwise press 2”. Here, 'delivery' is the sender information. Accordingly, the receiver can accept or reject the call connection with the caller by inputting number 1 or number 2.

A little more about the voice notification message. In the message storage unit 370, “The caller is ○○○. If you want to make a call, press No. 1, otherwise press No. 2” is pre-stored, and caller information for each phone number is pre-stored in the caller information storage unit 380 . The caller information may be a caller name or a service name provided by the caller. The phone connection unit 340 generates a voice notification message using the message storage unit 370 and the caller information storage unit 380, and transmits the generated voice notification message to the recipient terminal 200 through the recipient's call path. do. To elaborate on the generation of the voice notification message, the phone connection unit 340 searches for a matching phone number in the calling party information storage unit 380 with the calling number of the incoming call separately from the outgoing call to the called terminal 200, and the searched phone number Check the caller information corresponding to , and create a voice notification message by synthesizing the confirmed caller information into ○○○ of the voice message.

The phone connection unit 340 transmits the generated voice notification message to the called party terminal 200 through the called party communication path, and receives a response from the called party terminal 200 on whether to accept the call connection through the called party communication path. The telephone connection unit 340 connects (connects) the caller's call path and the receiver's call path only when the response from the receiver terminal 200 is to accept the call connection, thereby making a phone connection between the caller terminal 100 and the receiver terminal 200 make this happen According to this, even if the caller does not make a direct call to the receiver, the sender and the receiver can make a phone call, but the actual call record between the sender and the receiver is not left. In other words, it is because the communication company only records the fact of the call as shown in FIG. 4 .

In an embodiment, the phone connection unit 340 responds to an incoming call from the caller terminal 100 when the call connection acceptance is answered from the receiver terminal 200 between the server system 300 and the caller terminal 100 . A caller's call path may be established. That is, when the receiver rejects the call, the caller's call path is not formed, thereby preventing unnecessary resource waste and costly waste. Additionally, the server system 300 may further include a table deletion unit 350 . The table deletion unit 350 deletes the mapping table from the table storage unit 360 when the call path formed by the telephone connection unit 340 is disconnected, that is, when the call connection is released.

So far, with respect to the present invention, the preferred embodiments have been looked at. Those of ordinary skill in the art to which the present invention pertains will understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention.
