When a call is originated, a method of identifying a caller by a conventional receiver is a method in which a receiver's telephone terminal receives a caller's CID (Caller ID) and displays the received CID on the screen so that the receiver can check it. The receiver confirms the caller's information displayed on the screen and accepts or rejects the call.

Here, when the recipient's telephone terminal can not display the caller's information, the CID can not be displayed and the receiver can not confirm the caller's information. In addition, there is information of the caller that can not be confirmed only by the CID according to the service area of the receiver. To handle this information, the prior art has used the server and the associated facilities (eg, Huhu, this issue, etc.) on the receiver side to check the sender's additional information.

However, when a small business or an individual manages caller information separately, it is necessary to install hardware such as a server and a subsidiary facility and to install related software in order to identify the caller of the call received. Time, effort, and cost are consumed to build such an environment. In addition, a separate telephone terminal may be required for CID identification.

A call connection system 1 according to an embodiment of the present invention includes an originating telephone terminal 2 to which a caller originates a call, a PBX (Personal Digital Assistant) that receives a call originator's call through a PSTN (Public Switched Telephone Network) (Private Branch Exchange) exchanger 3 and a PBX exchange 3. The PBX exchanger 3 receives the call through the PBX exchange 3,

The originating telephone terminal 2 is a terminal to which a caller calls a recipient. For example, there is no particular restriction on a terminal having a call function including a mobile terminal, a smart terminal, an Internet telephone terminal, and a PSTN telephone terminal.

The PBX exchanger 3 corresponds to the call connection device of the present invention. The PBX exchange 3 receives an outgoing call generated from the originating telephone terminal 2 via the PSTN communication network. The originating telephone terminal 2 makes a call using the mobile number, the Internet number or the PSTN number. When the calling telephone terminal 2 calls the PSTN number, the receiving PBX exchange 3 receives the outgoing call. For example, in Seoul, the number starting with 02 corresponds to the PSTN number.

Here, when the PBX exchange 3 receives the outgoing call, it analyzes the call data and inquires the sender information set by the receiver for the origination number. When the caller information is inquired, the PBX exchange 3 connects the outgoing call to the incoming call terminal 4 based on the inquired caller information.

The called telephone terminal 4 is a terminal to which the outgoing call is connected through the PBX exchange 3 by being assigned the PSTN number. If there is no display device in the receiving telephone terminal 4, the receiving telephone terminal 4 receives the outgoing call and outputs a unique beep (ringing tone) according to the incoming signal of the received call data. Then, the receiver can distinguish the caller according to the tone of the call notifying the call reception. Of course, if the receiving telephone terminal 4 has a display device, the receiving telephone terminal 4 outputs the calling party display information of the received call data to the display device, and outputs a unique beep. Then, after confirming the beep or the beep + caller indication information, the receiver refuses to receive the call or receives the call and speaks with the caller.

The call connection system 1 may further include a data server 5 for setting caller information of a caller set by a receiver and providing a caller information search service to the PBX exchange 3 upon receiving an outgoing call have.

The data server 5 stores information set by the receiver as caller information for the caller. The data server 5 is requested to retrieve caller information from the PBX exchange 3, retrieves the requested caller information, and provides it to the PBX exchange 3.

Fig. 2 is a schematic internal structure of the PBX exchanger 3 of Fig. 1. Fig.

The PBX exchange 3 according to an embodiment of the present invention includes an outgoing call receiving unit 31 for receiving an outgoing call, a caller information searching unit 32 for searching for outgoing call information of the outgoing call, And a recipient telephone terminal connection unit 33 for connecting the call to the recipient telephone terminal 4.

The outgoing call reception unit 31 receives the call originated by the outgoing telephone terminal 2 through the PSTN telephone network.

The caller information searching unit 32 extracts a caller ID (e.g., an originating phone number) and a receiver ID (e.g., a received telephone number) from the received outgoing call, and extracts caller information corresponding to the extracted caller and receiver's ID Search.

Here, the searched sender information includes a receiver ID, a sender ID, and an incoming signal. The incoming call signal is a control signal for causing the incoming call terminal 4 to output a unique beep. Furthermore, the sender information may further include information of a caller that can be displayed at the receiving telephone terminal 4. [ In addition, the information of the sender may include information of the class of the customer set by the receiver.

Preferably, the sender information searching unit 32 transmits the sender ID and the receiver ID to the data server 5 to request the search of the sender information, and receives the sender information retrieved from the data server 5.

The recipient telephone terminal connection unit 33 connects the origination call to the recipient's telephone terminal using the searched sender information. Then, the receiving telephone terminal 4 receives the data of the connected outgoing call and outputs a ringing tone to notify the called party of the incoming call.

Here, the receiver's telephone terminal connection unit 33 can transmit the data of the outgoing call including the reception signal of the sender's information to the receiver's telephone terminal to connect the call.

Further, the PBX exchange 3 may further include a caller information setting unit 34. [ The caller information setting unit 34 sets and stores the caller information with respect to the calling number from the receiving telephone terminal 4. [

Preferably, the caller information setting unit 34 receives the keypad input information of the receiving telephone terminal 4 during the call between the receiver and the caller, and receives the caller information. For example, by using the dial keys 0 to 9 of the receiving telephone terminal 4 and the special character keys *, #, etc., unique caller information corresponding to a key button input by a receiver during a call with a caller is called caller information . Each key button is mapped to unique sender information. Then, the caller information setting unit 34 receives the input data of the key button from the receiving telephone terminal 4, transmits the received data to the data server 5, and transmits the mapped calling information to the calling number and the receiving number You can request to set up for

Furthermore, the receiving telephone terminal 4 having the character key can input the display information of the caller through the character key and the display device, and set it as the caller information. Or the Internet terminal of the receiver may access the data server 5 and set the display information of the caller to the receiver number and the caller number.

FIG. 3 is an exemplary view of caller information by customer class provided by the PBX exchange 3 of FIG.

3 is an example in which a company sets customer rating information as caller information for convenience of explanation. In the case of enterprise, dedicated service system is built and service is provided to check whether the caller is a good customer and to provide additional service for exclusive management for excellent customer. However, in the case of small businesses, managing the customer rating would require excessive system building costs or replacement of other devices related to the call connection.

However, by using the PBX exchanger (3) of the present invention, it is possible to manage the excellent customers by checking the caller without changing the device in order to manage the customer grade in the small companies, shops, etc. and to provide specialized services to the excellent customers Do. That is, high-quality customer management is possible without additional investment such as replacement of a telephone terminal for confirming a caller or a separate dedicated system.

For example, in the case of a customer center, the customer grade is divided into A, B, C, and D grades. During the call, the customer center staff can set or change the customer grade for the customer. When an employee receives an outgoing call, it is possible to respond to the customer by taking into account that it is the top-level customer when the information of the A-grade is output, and if the customer is the bad customer who frequently issues the claim, .

If a customer who purchases more than 3 times a month wants to register as a good customer, a company that does not have a dedicated system for customer management should manage customer ratings separately after completing the customer call. However, by using the PBX switcher 3 of the present invention, the receiving telephone terminal 4 can receive the customer rating information as the caller information at the time of call reception, and output the screen output or the ringing tone. The employee who confirmed the caller through the output information can change the customer rating through inputting a specific key button during the call with the customer and change the output information of the outgoing call.

Of course, the user of the receiving telephone terminal 4 may be a household. In the case of the home, the receiver can set the incoming call signal unique to the family member as the caller information via the receiving telephone terminal 4. [ Then, the receiving telephone terminal 4 outputs a unique ringing tone according to the incoming signal received from the PBX exchange 3 upon reception of the outgoing call. The user can distinguish the ringing tones output, check whether the caller is a family member, and selectively receive a call. On the other hand, if it is assumed that the caller is a stalker or a malicious caller, the caller can set the incoming call signal corresponding to the unique ringing tone as the caller information or register the rejection,

4 is a schematic flow diagram of a call connection method according to an embodiment of the present invention.

The call connection method of the present invention allows a recipient receiving a call through a PSTN telephone network to receive caller information and receive caller information without a separate construction equipment through a PBX exchange.

When the caller makes a call to the recipient telephone terminal 4 of the recipient subscribed to the PSTN telephone service by using the originating telephone terminal 2, the recipient PBX exchange 3 receives the origination call of the caller via the PSTN telephone network S31).

The PBX exchange 3 analyzes the data of the outgoing call, extracts the caller ID and the receiver ID, and retrieves the corresponding caller information from the DB using the extracted caller ID and the receiver ID as a key (S32).

Here, the caller information is information set by the receiver so that the receiver can check the caller when receiving a call. The sender information includes a receiver ID, a sender ID, and an incoming signal. The incoming call signal controls the incoming call terminal 4 to output a unique ringing tone to notify the recipient of call reception when an incoming call is received. That is, depending on the caller, the receiving telephone terminal 4 uniquely outputs the ringing tone according to the incoming signal to notify the receiver of the call reception.

Of course, the caller information may further include caller information that can be displayed through the display device of the receiving telephone terminal 4. [ In addition, the information of the sender may include the class identification information of the customer set by the receiver as shown in FIG.

Also, the DB storing the sender information can be constructed in the data server 5. [ Then, the PBX exchange 3 can transmit the sender ID and the receiver ID to the data server 5, request the search of the sender information, and receive the sender information retrieved from the DB of the data server 5. [

The PBX exchange 3 provides the searched sender information and connects the outgoing call with the incoming call terminal 4 (S33). Then, the receiving telephone terminal 4 receives the data of the connected outgoing call and outputs a ringing tone uniquely designated by the control signal to inform the receiver of the incoming call. Of course, if the receiving telephone terminal 4 has a display device, the information of the caller set by the receiver can be output through the display device. The user can confirm the caller through the outputted ringing tone and screen display information.

When a call is initiated by the recipient selecting a call and the caller and the recipient begin to talk, the recipient can set the sender's caller information using the incoming call terminal 4 during the call. Then, the PBX exchange 3 sets and stores the caller information for the calling number from the receiving telephone terminal 4 (S34).

Here, each key constituting the keypad of the receiving telephone terminal 4 is mapped with unique sender information. The PBX exchange 3 receives the input data of the key button from the receiving telephone terminal 4 and transmits the received input data to the data server 5 so as to transmit the mapped calling information to the calling number and the receiving number You can ask to set it up. Of course, it is also possible for the receiver to set the display information of the caller displayed through the display device of the receiving telephone terminal 4. [
