Apparatus and method for providing call state information {APPARATUS AND METHOD FOR PROVIDING CALL SIGNAL INFORMATION}

One embodiment of the present invention relates to an apparatus and method for providing call state information, and more particularly, to an apparatus and method for providing call information using an exchange.

In recent years, with the continuous evolution of communication networks, packet-based and circuit-based various wired / wireless communication networks are provided in addition to legacy communication networks such as PSTN networks, and telephone services in such wired / wireless communication networks are provided through various operators. have.

In particular, Internet telephony services using the SIP protocol in packet-based communication networks are emerging due to the increase in the Internet penetration rate and the wider bandwidth of Internet communication networks.

In addition, the Internet telephony service includes various service functions for the convenience of the user, and the BLF (Busy Lamp Field) function for checking the call state of a specific terminal is one of the representative service functions.

In the conventional BLF (Busy Lamp Field) method, as shown in FIG. 1, when a monitoring terminal to check a call state of a terminal transmits a message requesting the terminal state information to the exchange, the exchange requests the state information of the terminal. The message is transmitted to the terminal (101).

If the terminal then returns an acceptance message to provide status information, the exchange transmits the acceptance message to the monitoring terminal (102).

In addition, when the call state is changed (103), the terminal transmits the changed state information to the monitoring terminal through the exchange.

However, such a BLF method is to check and transmit the status information in the terminal, if there is a problem in the network situation or a problem in the terminal, there is a problem that the call state of the actual terminal may not be transmitted to the monitoring server in real time.

In addition, the communication unit 201 receives the call information transmitted from the calling terminal 221 and transmits it to the called terminal 222, or receives the call information transmitted from the called terminal 222 and sends it to the calling terminal 221. The call state of the terminal that transmits the call information may be checked based on the type of the received call information. In addition, when the call state of the terminal determined as the monitoring target is changed by the determiner 202, the caller 201 may generate call state information based on the changed call state and transmit the generated call state information to the transmitter 203.

In addition, when the monitoring unit 202 is configured to transmit a monitoring signal for setting a specific terminal as a destination from the monitoring terminal to the call unit 201, the communication unit 201 does not transmit the monitoring signal to the specific terminal, The specific terminal may be set as a monitoring target. In this case, the determination unit 202 may determine that the terminal to which the call is connected is the monitoring target when the terminal to which the call is connected is the specific terminal set as the monitoring target.

In addition, the transmitter 203 may generate the call state information as if it is transmitted from the terminal determined as the monitoring target, and transmit the call state information to the monitoring terminal 230.

In addition, the transmitter 203 may generate and transmit the call state information as if it is transmitted from the calling terminal 221 to the monitoring terminal 230.

In operation S404, the communication unit 201 receives a response signal from the receiving terminal 222 and transmits the response signal to the calling terminal 221. In this case, the response signal may be a response signal to the call signal transmitted in step S401.

In operation S405, the determination unit 202 confirms whether the receiving terminal 222 is a monitoring target. In detail, the determination unit 202 may determine that the reception terminal 222 is the monitoring target when the destination of the monitoring signal received in step S301 is the reception terminal 222.

In operation S406, the transmitter 203 transmits a call state of the receiver terminal 222 to the monitoring terminal 230.

In this case, the transmitter 202 may transmit the call state information indicating that the call state of the receiving terminal 222 is being received to the monitoring terminal 230. In addition, the transmitter 203 may generate and transmit the call state information as if it is transmitted from the receiving terminal 222 to the monitoring terminal 230.
