The present invention relates to providing an IP (Internet Protocol) -based call forwarding service, and more particularly, to an IP terminal (for example, a PC connected to the Internet) even when an incoming call cannot be received (for example, during a meeting). The present invention relates to an IP-based call forwarding service providing system and method thereof, and an IP terminal for a response according to call forwarding and a method thereof, which can quickly communicate a current situation to a caller through the caller.

The conventional Public Switched Telephone Network (PSTN) service provides a variety of services such as call forwarding, call waiting, and three-way calls to provide convenience to subscribers, thereby satisfying both subscribers and operators (win-win structure).

However, the Internet protocol (IP) based Internet service has the advantage of providing various multimedia services due to the large capacity of the service, whereas the existing line-based PSTN service plays a limited role in providing the service. Until now, most of the services of PSTN and IP (Internet Protocol) networks have been separately constructed and developed.

In addition, the conventional call forwarding service is a service for switching a call so that a subscriber can receive a call from his home phone when he is out, that is, a call to another phone number. It is a service that can be received by bypass, and provides convenience to the user in the situation where the Internet is not commercialized, and provides additional revenue by improving the reception rate.

However, in the modern world where the commercialization of the Internet and the meeting culture have been activated / generalized, there have been many situations where people cannot receive calls. Therefore, they are caught by themselves through personal computers (PCs) as well as mobile phones and general telephones. There is an increasing need to check on-line connections, especially for modern people who do not want to miss important phone calls.

That is, conventionally, when a call forwarding is performed to a mobile communication terminal or another telephone, the call forwarding service subscriber can receive most of the situation. However, in the situation of the modern man who has a lot of meetings and a long time working in front of a personal computer (PC). Increasingly, people are unable to answer important calls.

For example, if you are unable to answer a call because you are in a meeting, if you want to send a message urgently to the caller, if you want to communicate by voice instead of sending a text message depending on the urgency, If you want to send a text message when you need it through a program, you can receive call signal information to various call forwarding registration terminals (self-phone, mobile phone, PC) at the same time. The receiving party can receive the incoming call, and can further convey his situation in various forms such as a text message or a voice call according to the request of the receiving party.

In addition, the present invention, in particular in the case of a voice conversion call service (a service in which the exchange forms a call path with the calling terminal and transmits the voice message when the voice / conversion server converts the text information of the called party into a voice message). It is effective in providing more profits to operators who operate (PSTN, mobile communication network, etc.). This is because a normal telephone call charge, which is higher than a text message fee, can be added.

In addition, the present invention, the IP terminal such as a personal computer can send a text message quickly / promptly according to the text message transmission service, thereby providing the user (incoming party) immediateness and convenience for his situation transmission It can work.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which: There will be. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual explanatory diagram of an IP-based call forwarding service using voice conversion / messaging according to the present invention. Here, the IP terminal is an IP-based terminal capable of accessing the Internet (including a mobile Internet), and includes a PC, a notebook computer, a PDA, a portable Internet terminal, and the like.

Subscribers (subject recipients) register various terminal information (mobile phones, landlines, PCs, etc.) that they want to receive on the web (application server) dedicated to call forwarding service.

Thereafter, when the calling telephone (outgoing telephone number: "02-111-2222") tries to make a call to the landline telephone (incoming telephone number: "02-333-4444") of the other party (called party), the incoming call is exchanged at the exchange. When the transfer is performed and call information (CID information) arrives at the personal computer (PC) that has registered the call forwarding, the personal computer (PC) attempts to connect to the phone (collectively, it means “the call has arrived”). Inform the receiving party (PC user) through (100).

Then, the called party (PC user) enters the text to be transmitted to the caller (101), the voice service using the text / voice conversion according to the emergency (it is connected to the caller immediately and provides voice information, simply 'voice At least one of the following services can be directly transferred from a personal computer (hereinafter referred to as a text message transmission service).

In the case of the text message transmission service, a personal computer (PC) transmits text information input from the called party (PC user) to the messaging server through the IP network (Internet) together with the outgoing information (102). The text information is transmitted to the calling telephone in the form of a text message (103).

On the other hand, in the case of the voice conversion call service, the personal computer (PC) transmits the text information input from the called party (PC user) to the text / voice conversion server through the IP network (Internet) together with the calling information. The text / voice conversion server converts the text information into a voice message and then transmits the voice message and the outgoing information to the exchange (104). The exchange establishes a call (call channel) with the calling telephone and transmits the voice message (105). Since voice conversion call service is more expensive than simple text message transmission service, it is more advantageous for communication network (PSTN, mobile communication network, etc.) operators.

In short, first, the subscriber (recipient) registers the desired service on the call forwarding service-dedicated web (application server), and when the call comes from the caller, it shows outgoing information on the Internet (from a PC connected to the Internet) and receives the desired text from the subscriber. Then, depending on the urgency, it can be converted to voice through text / voice conversion and transmitted to the caller, or the text entered by the subscriber through a PC can be transmitted in the form of a text message, or a call can be made later on the mobile phone.

FIG. 2 is a diagram illustrating an embodiment of a call forwarding service registration / release method in an IP terminal according to the present invention. In particular, a call forwarding registration 21 of a subscriber for call forwarding service use in a personal computer (PC), a call forwarding The procedure of switching selection 22, function selection (service function selection) 23, and call forwarding cancellation 24 are shown.

In the case of a mobile phone / telephone, the call forwarding service registration 21 can be directly registered in the corresponding phone as in the conventional method, but the IP terminal (PC, etc.) can be applied to the application server through the web (application server) dedicated to the call forwarding service through the Internet. You can register at That is, various devices such as a mobile phone (mobile communication terminal), a landline phone, a personal computer (PC), and the like may be registered as a destination of the call forwarding service.

Once the call forwarding service is registered, it can be freely selected (call forwarding terminal selection) 22 within the registered range. That is, unlike the registration process 21, it is possible to conveniently switch between the registered device not only in a dedicated web but also in a general telephone.

Looking at the function selection (service function selection) 23 at the IP terminal (PC, etc.), the subscriber (the recipient) can change the voice conversion call service ("voice conversion immediately" on the PC screen) according to his needs or the urgency of the call. Forwarding ") or text messaging service, or just acknowledge and call later.

Finally, in the case of releasing call forwarding (24), it is possible to cancel the selection function in the IP terminal or to switch to another registered number.

Number, address information of the destination PC, call forwarding selection information, etc.), and provides corresponding service information to the service information request 302 of the exchange 32 (303). In addition, the application server 30 receives and processes a call forward registration / release request from the destination PC 35 through the IP network in relation to the IP-based call service (300).

When the exchange 32 receives an outgoing call from the outgoing telephone 31 (301), it checks whether the called party is subscribed to the call forwarding service, and if so, exchanges the service information to the application server 30. Request (302) and receive the service information (IP terminal address information since it is a case of PC call forwarding) in response (303), and the call is received through the IP network (Internet) using IP terminal address information (called PC address information). Sending information (caller's phone number, exchange identification information, etc.) is transmitted to the PC 35 (304). Subsequently, when the exchange 32 receives the voice message and the outgoing information from the text / voice conversion server 33 (307), it establishes a call path with the corresponding outgoing phone 31 using the outgoing phone number to deliver the voice message. 308.

The calling telephone 31 may be a wired telephone, a wireless communication terminal (mobile phone), a VoIP terminal, or the like. Accordingly, the switch 32 may include a mobile switching center (MSC) for a wireless communication network, a service switching point (SSP) for a wired communication network (PSTN), and a soft switch for a VoIP network. Switch) and the like, and are connected to the application server 30 through a service control point (SCP).

When the destination PC 35 receives the outgoing information from the switch 32 via the IP network (Internet) (304), the screen output notifies the user that the call is from a specific calling number. In this regard, the called party may not respond or may decide whether to transmit a text message (for a text message transmission service) / voice transmission (for a voice conversion call service) (305).

In the case of the text message transmission service, when the called party inputs a "message to sender" as a text message through the called PC 35, the called PC 35 transmits the calling information (outgoing call received from the exchange) together with the inputted text information. Information) is transmitted to the text-to-speech server 33 via the IP network (Internet) (306). Then, the text-to-speech conversion server 33 converts the text information into the voice message, and then transmits the voice message and the caller's telephone number to the exchange 32 using the 'exchange identification information' in the outgoing information (307).

On the other hand, in the case of the voice conversion call service, when the called party inputs a "message to sender" through the destination PC 35 as a text, the destination PC 35 receives outgoing information (from the exchange) together with the inputted text information. One outgoing information) is transmitted to the messaging server 34 via the IP network (Internet) (309). Then, the messaging server 34 transmits the received text information to the calling telephone 31 in the form of a text message by using the calling information (calling phone number) (310).

4 is a flow chart of an embodiment of a method for providing an IP-based call forwarding service using voice conversion according to the present invention. For example, when an attempt is made to make a phone call to a mobile phone of a party (a call destination) to be called, A case where the call is received by the divert service to the destination PC of the call recipient.

When the outgoing telephone 31 calls a call for a telephone call (400), the switch 32 checks whether the called party is subscribed to the call forwarding service (402), and if so, the application server (30). Request the service information (404).

When the exchange 32 receives the service information (the IP terminal address information because it is the case of the call forwarding to the IP terminal) from the application server 30 (406), the IP network (IP address information) using the IP terminal address information (called PC address information) Sending information (caller's phone number, exchange identification information, etc.) is transmitted to the destination PC 35 through the Internet (408).

When the destination PC 35 receives outgoing information from the exchange 32, it informs the called party that the called party has arrived (the call came from a specific calling number) through the screen output (see "100" in Fig. 1).

Accordingly, when the called party enters a message through the input window on the PC screen (for example, "I will call you in 1 hour since I am in a meeting") as a text (410) and executes the call, The PC 35 transmits outgoing information (outgoing information received from the exchange) together with the inputted text information (that is, the text information inputted by the called party to the caller) through the IP network (Internet). 33) (412). The embodiment shown in FIG. 4 corresponds to a case where the transmission service type is set to "voice conversion call service" ("1" in "23" in FIG. 2).

The text / voice conversion server 33 converts the text information received from the destination PC 35 into a voice message (414), and then converts the voice message and the caller's telephone number by using the 'exchange identification information' in the outgoing information. 32) (416).

The exchange 32 transmits a voice message by setting a call path with the corresponding calling phone 31 using the calling phone number (418). The caller then hears the message sent by the called party as if the telephone connection was established.
