The present invention relates to a call connection system and method, and more particularly, when a caller wants to make an urgent call connection even after notifying the caller that the current situation of the terminal user is difficult to answer, an additional fee is unnecessary. The present invention relates to an optional emergency call connection system and method for blocking a spam attempt attempting a call.

In modern times, as the usage of mobile communication devices, i.e., mobile communication devices such as general mobile communication devices and PDA phones, increases, the calls to the mobile communication devices are disturbed or difficult during meetings, driving or important conversations. Increasingly, the degree is very serious, depending on the user has reached an uncomfortable level. In addition, it is recommended to refrain from using mobile communication devices in public places where many people gather or in libraries and conference rooms requiring quietness. do.

As such, when a user calls a user of a mobile communication device such as during a meeting, a task requiring concentration, driving, an important conversation, or in a public place where it is not easy to receive a call, the user may call himself or another While taking the inconvenience of people, they had to answer the phone directly or unilaterally hang up without knowing whether the phone was urgent. Alternatively, when a call is received, the call is sent to the other party by pressing a predetermined button on the mobile communication device.

In addition, after confirming the caller attempting to connect to the call through the caller ID service, a message indicating that the call cannot be received may be transmitted in the above-described manner.

However, through such a conventional method, it is not possible to confirm who is the target of the advertisement / promotional telephone and the incoming telephone number that cannot identify who is the target of the incoming telephone number, but it is classified as an important telephone case of communication device. Since the recipient, the user, could not receive the call, it was not possible to determine how important and urgent the call was before the call was received.

Furthermore, even when the receiver is difficult to answer the call, even if the incoming call does not receive an incoming call, when the incoming vibration or the ringing tone is progressed, there is a frequent occurrence of an important call.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to request an emergency call connection when an emergency call connection service is established through mode switching of a communication terminal by a user in a situation where it is difficult to answer a call. The present invention provides a selective emergency call connection system and method for blocking an incoming / outgoing connection for an unnecessary or insignificant outgoing request by having a caller charge a separate fee.

The present invention for achieving this purpose is a first communication terminal which is switched to the emergency call mode of the caller selection by the user's settings, the second communication terminal for making a call request to the first communication terminal, and the caller selection of the first communication terminal The emergency call connection service is executed through the emergency call mode of the mobile terminal, and a corresponding heavy charge imposition guide message is sent to the second communication terminal, and the incoming call signal is transmitted to the first communication terminal based on the response of the second communication terminal returned. It is implemented including a service management server for establishing an incoming and outgoing call by passing.

Selective emergency call connection method according to the first aspect of the present invention for achieving the above object, (A) the first communication terminal is switched to the emergency call mode of the caller selection due to user settings, (B) service management Sending, by the server, a heavy charge imposition guide message corresponding to the emergency call mode of the caller selection to a second communication terminal requesting to transmit to the first communication terminal; (c) the second to the heavy charge imposed guide message; And forwarding an incoming signal to the first communication terminal based on the response of the communication terminal, and (d) setting up an incoming / outgoing call to the incoming response of the first communication terminal.

In addition, the selective emergency call connection system according to the second aspect of the present invention for achieving the above object is a first communication terminal which is switched to the emergency call mode of caller selection by the setting by the situation that the user is difficult to answer the call; 1 Service management for setting up an incoming / outgoing call call based on a second communication terminal requesting an outgoing call to the communication terminal and the second communication terminal by sending a heavy charge imposition guide message corresponding to the emergency call mode of the caller selection. It characterized in that it comprises a server.

Hereinafter, a preferred embodiment of the selective emergency call connection system according to the present invention with reference to the accompanying drawings in more detail.

1 is a block diagram showing an optional emergency call connection system according to an embodiment of the present invention. As shown in Fig. 1, the selective emergency call connection system is configured to switch to the emergency call mode of caller selection by the user's setting when the user is in a difficult situation to receive a call, such as during a meeting or during an important conversation. A terminal 100, a second communication terminal 400 for making a call request via a wired or wireless based communication network 200 as a counterpart terminal for making a telephone call to the first communication terminal 100, and the first communication Due to the emergency call mode switching of the caller selection of the terminal 100, an emergency call connection service is executed for the first communication terminal 100, and the second communication terminal 400 performs the first communication terminal 100. If the call request is sent to the second communication terminal 400 sends a heavy charge imposition guide message corresponding to the emergency call mode of the caller selection, based on the response to the first communication terminal 100 And a service management server 300 for setting up an incoming / outgoing call as the incoming signal is transmitted.

In addition, when the first communication terminal 100 is in a situation where the user is difficult to answer the call, the first communication terminal 100 switches the mode through a preset hot-key corresponding to the emergency call mode of the caller selection, and returns to the general phone call mode. The same goes for re-conversion. The setting of the mode switching may be implemented in a separate manner such as the sequential setting of the user according to the menu in addition to the above-described method through the hot-key.

The communication network is not only implemented as a synchronous or asynchronous network, but also a second generation communication network capable of supporting voice and text services and supporting Internet services, such as a CDMA communication method, or further, such as WCDMA, HSDPA, WIBRO, etc. Like a communication method, a video service may be implemented through an executable third generation communication network.

Hereinafter, the operation of the selective emergency call connection system according to the present invention with reference to the accompanying drawings in more detail as follows.

FIG. 2 is a flowchart illustrating an operation of the system shown in FIG. 1. As shown in FIG. 2, the selective emergency call connection method may be performed when a user receiving an incoming call is in a situation where it is difficult to receive a call such as a meeting time or an important conversation. The first communication terminal 100 is switched to the emergency call mode of the caller selection (S100). Accordingly, the service management server 300 managing the emergency call connection service of caller selection receives the emergency call connection service request of the first communication terminal 100 to provide the corresponding service for the first communication terminal 100. It executes (S102-S104).

In this state, when the second communication terminal 400 makes a call request against the first communication terminal 100 (S106), the service management server 300 is an emergency call connection service set in the first communication terminal 100 According to the execution, the second communication terminal 400 said, 'It is difficult to answer the call now. If you are in a hurry, please press *. When the phone is connected, a separate charge will be charged in addition to the call charges.

The caller of the second communication terminal 400 receiving the heavy charge guide message will attempt to make a telephone call in an urgent situation even if a separate fee is charged, and if the telephone connection is attempted for the purpose of advertising / publicity, etc. It won't try to connect to it until you pay an extra fee. Accordingly, when the caller of the second communication terminal 400 requests an emergency call connection (S110), the service management server 300 responds to the first communication terminal 100 in response to the incoming call signal for the emergency call connection service. It will be delivered (S112).

When the first communication terminal 100 responds to the incoming signal in step S112 (S114), an incoming / outgoing call connection is executed between the first communication terminal and the second communication terminal 400 (S116).

Here, the service management server 300 does not transmit the incoming signal to the first communication terminal 100 when the second communication terminal 400 does not set an emergency call connection by charging a separate fee, The first communication terminal 100 may deliver a telephone call request corresponding to the user only in an emergency situation.

In addition, in step S116, when the first communication terminal 100 does not answer the incoming call, the service management server 300 to cancel the additional charges imposed by the emergency call connection to the second communication terminal 400 do.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.

Therefore, in the present invention, when the emergency call connection service is set through the mode switching of the communication terminal by the user in a situation where it is difficult to answer the call, an additional charge is unnecessary or not important by charging a caller requesting an urgent call connection. By blocking incoming and outgoing connection to the request, the recipient who is requested for the telephone call does not have to respond to the unnecessary telephone call request itself, and in particular, has the advantage of blocking 100% of the advertisement / promotional call.
