The present invention relates to an apparatus and method for transferring a call to an Internet telephone according to status information of a messenger, and a computer-readable recording medium recording a program for realizing the method. More specifically, the present invention relates to a messenger and an internet telephone. Combined with, the call transfer service device and method of the Internet phone for automatically transferring the call to the Internet phone to the user's mobile phone or voicemail in accordance with the status information of the messenger (that is, the absence status) and the method; The present invention relates to a computer-readable recording medium having recorded thereon a program for realizing this.

Currently, there are two methods of providing a call forwarding service for a general call: an exchange-based call forwarding service, and a 'pass call service' using an intelligent network system.

The switch-based call transfer service (call forwarding service) is a method of registering an automatic routing using a telephone when a subscriber goes out, and the 'pass call service' is received for a predetermined time when a telephone call is made by a landline. An intelligent network service that automatically routes to mobile phones.

However, the 'switch-based call forwarding service (routing service)' for routing missed calls is a cumbersome problem because the subscriber must press the code directly on the telephone to select the call forwarding / release when the subscriber is out and back. have.

In addition, in the case of the 'pass call service' using the intelligent network system, the caller must wait for a long time (no answer waiting time) since the call is routed to the forwarding number only after waiting for the non-response waiting time, and thus the completion rate of the call connection is inevitably reduced. none.

However, services currently provided for communication on the Internet include a messenger and a VoIP service. However, since both the messenger service and the VoIP service are provided through the Internet, it is difficult to use the service unless the user is seated. That is, it is impossible to use both services while the user is away. Therefore, even when the user is in the idle state, the Internet telephone can be unnecessarily ringing.

Therefore, by interfacing the status information of the messenger to the Internet phone, it is possible to prevent the Internet phone from ringing when the user is away, and to automatically connect to the mobile phone, so that the incoming call can be made even when you are away. .

The present invention has been proposed to meet the above requirements, by combining a messenger and an Internet phone, the call is automatically transferred to the user's mobile phone or voicemail according to the messenger's status information (that is, the absence status) It is an object of the present invention to provide a call transfer service apparatus for an internet telephone and a method thereof, and a computer-readable recording medium storing a program for realizing the method.

The present invention uses the state of the messenger to the Internet phone, when the messenger is away, the Internet phone does not ring and stores the message in the voicemail or transfers the call to another mobile phone of the user.

Since both messenger and internet phone are provided through the Internet, it is difficult to use the service unless the user is seated. Therefore, when the status information of the messenger is linked to the Internet phone as in the present invention, when the user is away, the phone can be prevented from ringing without need, and the call is automatically received even when the user is absent. It is possible.

As such, when the user is away, in order to enable a call transfer, a call transfer number must be registered through a service subscription or the like, and a communication function for transferring a message between a messenger and an Internet telephone server and applying it to a service is provided. need.

According to the present invention, when an Internet phone and a messenger user are away from the office environment, it is possible to prevent an unanswered call from ringing, thereby preventing noise of a telephone ringing sound, thereby improving the work environment. In addition, like the existing exchange-based call transfer or the intelligent network service called Passcall, the call transfer is not performed by manually registering the call or transferring the call after several rings. It is more convenient to use.

Then, when a call is received from the caller to the user, the VoIP agent 41 of the Internet telephone server 40 receives the subscriber's status information (messenger current status) from the database (DB) 11 of the service management system (SMS) 10. Information), and receives the registered call transfer number (wired / wireless telephone number to be transferred in the absence of subscriber) to connect the call. Or, the Internet telephone terminal of the Internet telephone user is switched to the voice mailbox mode.

Therefore, the database (DB) 11 of the service management system (SMS) 10 includes messenger user information (e.g., messenger ID), Internet telephone user information (e.g., Internet phone terminal number), and messenger status information. Call mapping information (ie, control information for converting a wired / wireless telephone number to be transferred or an Internet telephone terminal of an internet user to voicemail mode) is mapped and stored when the subscriber is absent. The status information of the messenger is updated in real time according to the status of the messenger, and the call transfer information can be arbitrarily selected and changed by a service subscriber in the Internet environment.

2 is a flowchart illustrating a method for call transfer service of an Internet phone based on status information of a messenger according to the present invention.

First, when a user who is subscribed to a call transfer service of an Internet phone according to the status information of a messenger does not use a messenger for a certain period of time and is in an absent state, the messenger agent 31 detects this and receives subscriber information (eg, User ID) and status information (eg, away or subscriber absent information) are transmitted to the status management server 20 (step 201).

Then, the state management server 20 receives this information (subscriber information, messenger current state information (ie, away or subscriber absent information)) and transmits the information of the Internet phone user mapped to the messenger user to the service management system (SMS). (202) retrieved from the database (DB) 11 of (10), and this information (Internet telephone user information, messenger current status information (i.e., away or subscriber absent information)) is stored in the VoIP of the Internet telephone server 40. Send to agent 41 (203).

Next, the VoIP agent 41 receives this information (Internet user information, messenger current status information (ie, away or subscriber absent information)), and stores the user status information (messenger current status information) of the database (DB). Update is made to (11) (204).

Then, when a call is received from the caller to the user (that is, when the call is made from the calling terminal to the called Internet telephone terminal) (205), the VoIP agent 41 of the Internet telephone server 40 is connected to the service management system (SMS) ( 10 by querying the subscriber's status information (messenger current status information (i.e., away or subscriber absent information)) from the database (DB) 11 (206), and recognizing that the subscriber is absent (away), After notifying the calling terminal that the subscriber is not available and sending the announcement about the call transfer (207), the call is requested by the registered call transfer number (wired / wireless telephone number to be transferred when the subscriber is absent) (208). A call is made between the terminal and the call transfer terminal (209).

Of course, the process of notifying the calling terminal that the subscriber is not present and sending the announcement regarding the call transfer (207) is omitted, and recognizing that the subscriber is away (away), the registered call transfer number (subscriber missed call) Call connection to the wired / wireless telephone number to be switched automatically may be requested (208) to make a call between the calling terminal and the call switching terminal (209).

In addition, after recognizing that the subscriber is absent (away), after notifying the calling terminal that the subscriber is absent and sending the announcement about the call transfer (207), the Internet telephone terminal (incoming Internet telephone terminal) of the Internet telephone user is changed. By switching to voicemail mode, the caller's voice and telephone number can be recorded. In this case, it is obvious that the subscriber can be automatically switched to the voicemail mode by omitting the step 207 of notifying the caller that the subscriber is not available and transmitting the announcement regarding the call transfer.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.
