The present invention relates to a call forwarding device and a method thereof, and more particularly, to a call forwarding device and a method using a prepaid card for receiving a domestic mobile phone from abroad.

In general, Voice over Internet Protocol (VoIP) technology has recently been in the spotlight due to the reduction of communication charges through efficient use of existing network resources and the ease of management through integration of telephone network and data network. .

Voice communication over the Internet, not the public switched network (PSTN), has been developing rapidly since the first implementation of Vocaltec, Inc., with Internet phone software. This early model, called the PC-to-PC model, runs on a personal computer with handset, sound card, speakers, microphone, and modem (or network card). It is a device that compresses and converts it into IP packets and transmits them through the Internet to make a call.

As technology has advanced, a dedicated gateway server for Internet calls has emerged, acting as an interface between the Internet and the public switched network. The gateway server is equipped with a voice card, allowing users to make Internet calls using standard telephones.

FIG. 1 schematically illustrates the overall configuration of such a conventional so-called phone-to-phone type internet phone system. When the caller dials the telephone number of the Internet phone service provider, a call originated from the caller's telephone 11 is transferred to the nearest gateway server 13 through the public switched telephone network 12. The gateway server 13 converts the received analog voice signal into a digital signal, compresses it, and converts it into an IP (Internet Protocol) packet.

On the other hand, the gateway server 13 is the IP of the gateway 15 closest to the called party's telephone 17 from the other party's telephone number input from the calling party's telephone 11 to the gatekeeper 18 connected on the Internet 14. Request and transmit these packets to the gateway 15 having the corresponding IP. The gatekeeper 18 may also be referred to as a call agent or a call server. The gatekeeper 18 is a node on the Internet that performs address translation between heterogeneous networks, that is, a telephone number and an IP address. It also performs subscriber authentication based on the Internet Telephony Signaling Protocol (Layer) layer, and is generally a server managed by a service provider.

Here, ITSP (Internet Telephony Signaling Protocol) defines the signaling and control methods required for call setup and telephone calls in VoIP systems such as H.323, Session Initiation Protocol (SIP) / Media Gateway Control Protocol (MGCP), etc. Means the standard protocol.

Such a gatekeeper server 18 may be located at any point on the Internet 14, but may be physically implemented within the same server as the gateway server 13, or may not be the Internet as shown by the dotted lines in the figure. It may be a server connected by an internal LAN.

The receiver gateway 15 reconstructs, reconstructs and converts the received packets and converts the call to the receiver through the public switching network 16 using the telephone number of the receiver telephone 17 decoded from the signal packet. Connect.

Such Internet phones are spreading rapidly because they are superior and inexpensive in terms of network use efficiency compared to general phones using public switched networks. However, since the Internet phone has to go through a gateway, the method of use is complicated, so it is not used for local calls but mainly for international calls.

On the other hand, when using the international roaming service in the existing public switched network, if a person with a domestic phone number stays in a foreign country for business trips, etc., someone who does not know this in Korea calls the person's phone number and receives a guide message. It was possible to automatically dial the local telephone number of a roaming service user in a foreign country. However, such international telephone roaming service of public switched networks is very expensive and its use is restricted.

In addition, the roaming (roaming) is a service that enables communication in the service area of different communication providers. In other words, there are three PCS mobile phone operators in Korea, each with its own service network. As a result, some companies may exhibit areas of good service and poor service. In this case, it would be very convenient if the companies allied to each other and joined any company to connect the service network to each other to receive quality service anywhere. As such, a service that extends the quality and scope of services by cooperating with communication companies is called a roaming service.

If a domestic company decides to roam with a company in the United States or Japan, the person who joins the company can use the phone as it is in Korea, even if the other company is providing the service even if the mobile phone is brought to the United States or Japan. Will be.

The mobile phone international roaming service used to date is a type of service in which a mobile phone service company has a roaming contract with a partner country company and provides a certain procedure and an additional fee when the customer requests it. Automatic roaming is a service that uses the same mobile phone that the customer used to go out, and rental roaming is a service that rents the mobile phone regardless of whether the customer joins before going abroad.

This is because the call quality is relatively good and mobile, so there is the convenience of free use of the call, and in the case of automatic roaming, there is no change in the phone number, so it is possible to make a call without any inconvenience for domestic callers.

However, in addition to the international roaming fee, the domestic country pays a fee equivalent to that of an international call, which is expensive, and a domestic user must pay a fee for roaming. In addition, the use of the service may be restricted depending on the telecommunication company's telecommunications network (including domestic and party) or local circumstances within the country. In case of renting roaming, mobile phone rent must be paid separately. In addition, although the call environment may be convenient for structural reasons, the burden of the most sensitive fee is too great for the user.

In addition, in the form of separate telecommunications service providers, equipment leasing and call intensive services are provided to customers by low-cost discounts on telecommunication facilities (including network) or call usage fees by contracts for service provision by backbone network operators or counterpart telecommunication companies. It is a new telecommunications company that pursues operating profits by discounting rates. Self-owned equipment operators are operators who own their own equipment or networks, and mainly use their own networks or equipment to provide international calls to customers at low cost. Occasionally, the contractor uses the network or equipment of the main network operator as needed. This is a cost saving effect of owning a facility, providing customers with good call quality and relatively low call charges.

Their use method is to service customers at home and abroad or use prepaid communication card and use as much as the corresponding amount by using separately assigned call access number. Internet phone user uses ID and password in the same form as the conventional dial pad. Make an international call after connecting.

This service is very cheap and there is an advantage that it can be freely used as needed without special sign-up procedure when using the prepaid communication card.However, the call quality is relatively lower than that of the main network operator and there is a risk of disconnection. The use environment is relatively limited. In addition, it is inconvenient because the call button has to press the number button relatively more than the main network operator when using the telephone.When the congestion or discount rate time zone of the international internet network does not match with the other country, depending on the usage time, the connection may be poor. There is also a problem that the probability of fraud can not be ignored when using a prepaid card of a telecommunications service company to make international calls.

In particular, the international automatic roaming service, which is more vulnerable to the reality that the business area is set as the global stage these days, is becoming a big inconvenience for the frequent business operators (trade business, walking prizes, etc.) running in the field. There is an urgent need for an international mobile roaming system that is simple in procedure, has good sound quality, is low in cost and easy to use.

The present invention has been made to solve the above problems, and to provide a call forwarding apparatus and method using a toll-free prepaid card in combination with a VoIP service and a call forwarding service for receiving a domestic mobile phone call from abroad.

And switching from the received prepaid card to register the second incoming call fee when the call is completed.

And registering the telephone number of the call forwarding service device to be forwarded first to the switching device and simultaneously registering the telephone number to be forwarded second to the call forwarding service device. It is desirable to automatically forward the call.

In addition, a call forwarding method using a call forwarding service device configured to receive a call and transfer the call to the registered phone number of the called party, generating a call to the call forwarding service device, receiving the call and calling the phone number of the called party; The call forwarding may be configured to include the step of forwarding the call and when the call is completed, charging the forwarded call charge on the received prepaid card registered by the receiver.

Further, it is more preferable that the forwarding service apparatus is configured to input a domestic telephone number through a message upon receiving the call, and automatically forwards the incoming call to the registered recipient's telephone number when the domestic telephone number is input. .

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

The present invention is a technology for receiving a call to a Korean mobile phone number by using a receive-only payment card prepaid in advance to the incoming call to the mobile phone or landline used abroad.

That is, like a conventional telephone card, a predetermined fee is paid when a card purchase customer applying for a call forward using a reception-only prepaid card product filled with a predetermined amount receives a call.

2 is a view schematically showing a call forwarding apparatus using a reception-only prepaid card. A call forwarding apparatus using a reception prepaid card according to the present invention includes a caller (110), a PSTN network (120), and call forwarding. The service device 130 and the receiver 140 carrying the overseas mobile phone is configured.

The caller 110 is a call generating device composed of a conventional wired / wireless telephone possessed by an unspecified number, and the PSTN network 120 transmits a telephone number of an exchange device 122 and an outgoing telephone number to perform a general communication relay to the receiver's telephone. It consists of a call forwarding unit 124 to connect is configured to perform a normal mobile communication relay service and provides a primary call forwarding service. In particular, in the present invention, when the caller 110 generates a call using the domestic wired or wireless telephone of the applicant for the call forwarding service, the caller 110 is configured to be forwarded to the call forwarding service device 130 of the service provider of the present invention. That is, when a call is generated, it is operated to receive an incoming call to the access telephone number of the service provider of the present invention. Since the mobile communication network 120 is the same as the existing communication network, a detailed description thereof will be omitted.

Call forwarding service device 130 according to the present invention is connected to the PSTN as an Internet phone gateway (Gateway) equipment to play the voice and receive the caller's input number to be forwarded to the pre-registered recipient phone 140 VoIP gateway 132, which is a secondary call forwarding service device, and a billing server 134, which performs prepaid billing for the used telephone bill.

In addition, the VoIP gateway 132 is connected to the site that operates the call forwarding device of the present invention, the telephone number (mobile phone, general phone) that can be received in the country, the card number indicated on the received prepaid card and the overseas callable Provides a service to register by specifying a telephone number (hereinafter referred to as pre-registration matter).

Preferably, the site has a separate "call forwarding service request" corner so that the user can easily register the pre-registration items using the received prepaid card purchased by the user. When clicked, the comment is output and configured using a graphical user interface (GUI) so that a user can easily register the pre-registration items.

Hereinafter, a call forwarding service application and a method using a received prepaid card according to an embodiment of the present invention will be described.

3 is a flowchart illustrating a call forwarding service application process using a received prepaid card.

First, a user who wants to receive an incoming call service accesses a site providing a service of the present invention through the Internet (S210).

As described above, the site has a separate "call forwarding service request" corner for easy registration of pre-registration items, and when the user clicks on the "call forwarding service request" field, the message is output and the user can easily register the registered matters. It is configured by using Graphic User Interface (GUI) to register them.

Subsequently, the call forwarding service application is requested while viewing the comment and the GUI screen related to the call forwarding service application provided by the site (S212).

Pre-registration allows registration, including telephone numbers used in Korea (including wired and wireless), telephone numbers that can be received from overseas, and card numbers of purchased prepaid cards (S214).

Repeat the registration necessary for the pre-registration, and ends when all the registration (S216).

Steps S210 to S216 are not only possible through the Internet as described above, but can also be applied through wired and wireless telephones as in a conventional method, and the site may be a site of a mobile communication company or a service provider for providing a service according to the present invention. It could be a site. That is, if the service provider does not know the access phone number, the service applicant is to provide the service when the request is made to the phone number used in the country. Therefore, in the case of applying for the service through the site of the mobile communication company to enter the access telephone number of the company providing the service to automatically ring the incoming call service device 130.

As described above, when the pre-registration is completed, a call forwarding service may be provided to receive a call from an unspecified number of domestic users anywhere.

Hereinafter, a process of call forwarding using a domestic telephone number will be described. 4 is a flowchart illustrating an incoming process. When the caller 110 generates a call to a specific phone number as shown in the drawing, the call is a call recognition service provider using the PSTN network 120 of the mobile communication service provider (S220). The call forwarding service S221 using the call forwarding service device 130 is determined.

That is, the steps S220 to S221 are for distinguishing whether the caller 110 has applied for call forwarding to a call using a domestic phone number or a call to a service provider's access phone number.

If it is determined in step S220 that the call using the mobile communication company's mobile communication network 120, the first incoming call to the service provider of the service provider of the present invention applied for call forwarding to the mobile carrier to apply for the call forwarding service (S231) ) Is connected to the VoIP gateway 132 (S231).

Referring to FIG. 2, the caller 110 generates a call to the PSTN network 120 (①) and the process of switching to the call forwarding service device 130 from the PSTN network 120 (③) and the receiver phone 140. Is a process of converting to ().

In addition, when a direct call is generated to the VoIP gateway 132 in step S221 (ⓐ-> ⓑ in FIG. 1) and when the call is forwarded to the VoIP gateway 132 in step S230, the caller 110 calls the service requester. The phone number input comment is output through the ARS to allow the call forwarding to the receiver phone 140 (S222). In other words, the message "Please enter the recipient's telephone number again".

The VoIP gateway 132 forwards the call to the recipient's phone number input according to the comment and allows the call to be made with each other (S223).

When the call is terminated (S224), the call forwarding service device 130 collects the charge corresponding to the call charge used by the billing server 134 from the charge of the received prepaid card (S225).

In the present invention, for the convenience of description, the receiver has been described to be forwarded to the overseas mobile phone 140, but can be forwarded, including a wired and wireless telephone number.

Thereafter, if the charge of the received prepaid card is exhausted by repeating the above process, the card is charged after using the received prepaid card after accessing the operation site of the service provider after purchasing the card.

As described above, the unspecified many can use it at a lower price as needed, such as a regular telephone prepaid calling card, without having to pay for advance reservation and expensive communication.

In particular, if you live abroad and travel abroad frequently, you can receive calls to any phone number that you can receive locally through a call forwarding call from anywhere in the world through your domestic contacts. It is easy to use anytime, anywhere by using the prepaid card.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and variations belong to the appended claims.

As described above, the call forwarding device and the method according to the present invention can be more conveniently used by many foreign visitors who come to a foreign country for a relatively short period of time. You may not have to pay high fees such as mobile phone charges.

Unlike the roaming service provided by the existing carriers, the company charges a low-cost rate and proceeds with differentiating business, so unlike the forwarding service provided by the VoIP service, it can conduct business against an unspecified number of people who do not use the product.
