Description

Phone call state management device {APPARATUS FOR MANAGEMENT OF TELEPHONE CONVERSATION STATUS}

The present invention relates to a telephone call state management method, and more particularly, to a telephone call state management method that enables each terminal to know when a new participant is generated or terminated in a system for transmitting and receiving voice and data through a packet network. It is about.

In the conventional system for transmitting and receiving voice and data using a packet network, the International Telecommunication Union (ITU-T) has designated a protocol (H.323) in which a voice channel and a signal channel are strictly separated as a terminal specification.

However, in the conventional technology, the protocol applied to each terminal (H.323) does not have information that can be known each time a network participant is created or destroyed, so each telephone call is requested in the unknown state. There was a problem in that the call was requested by repeatedly connecting and disconnecting the participants.

Accordingly, the present invention was created to solve the above-mentioned conventional problems, and the call is detected and displayed every time a new participant is created or terminated in a system for transmitting and receiving voice and data through a packet network. Its purpose is to provide a method for managing the state of a telephone call so that it is immediately known whether it is possible.

Hereinafter, a call setup process and a state change according to the present invention configured as described above will be described with reference to the accompanying drawings.

First, FIG. 3 is a flowchart illustrating a process of making a call. As shown in FIG. 3, when the user picks up the handset (Off-Hook) to make a call in the idle state, the status information is broadcast. A dial tone is generated and a timer is started. At this time, when a preset button (for example, 9) is pressed, a new dial tone is generated to notify the trunk line connection. When a timer for receiving a number is started and a button (a function key such as a number or a redial or a speed key) is input, the timer is stopped.

At this time, when a predetermined time elapses during the number input, the handset must be put down (On-Hook) and then turned back on (Off-Hook) to receive the input number.

Therefore, if all predetermined telephone numbers are inputted by repeating the above process (Full Info), the process for call setup is performed.

At this time, if the status information (Information) is input even during the telephone call, the status is displayed through the status display unit (LED) 10 while being updated (Update Status) with the new information.

Next, FIG. 4 is a flowchart showing a call setup process with the terminal (Internet phone) of the input number after the input of the terminal for setting up the call in FIG. 3 is completed. setup) is transmitted to the other party's terminal in a unicast manner, and if there is no response for a certain period of time, it returns to the process of FIG. And ring back tone (ring back tone) is ringing and the call is picked up by the receiver of the opposite terminal is connected to be able to talk.

At this time, if the handset is put down after one end of the call as shown in FIG. 5 (On-Hook), the set call is terminated, the state is broadcasted, and the IDLE is returned to the idle state. The call can be switched to another terminal by pressing the Hold key.

Next, FIG. 6 is a flowchart illustrating a response process of a receiving terminal according to the call setup process. As shown in FIG. 6, when a status message from another terminal is received in an idle state, the receiving unit displays a status LED. The status is displayed, and when the setup message is received and the setup accept is sent, the ring rings. When the user lifts the handset (OFF-HOOK), the call is set up and the call is completed. If you put down (ON HOOK) will be disconnected and broadcast the status to make a state (IDLE) to call again with other terminals.

As described above, the apparatus for managing a telephone call state of the present invention detects and displays the state whenever a new participant is created or terminated in a system for transmitting and receiving voice and data through a packet network, so that it is possible to immediately know whether a call is possible. Doing so increases the efficiency of work and prevents waste of time.
