Preferably, the call processing server in the present invention is characterized by calculating the communication charges using the rate set for each distance and the distance between the originating IP terminal and the destination IP terminal.

In the broadband integrated network according to the present invention, a method for calculating a location-based fee comprises: a first step of extracting location information of the originating IP terminal from the originating message when a start message is received from the originating IP terminal; If the acknowledgment message is received from the called IP terminal, extracting location information of the called IP terminal from the acknowledgment message; A third step of calculating a distance between the calling IP terminal and the called IP terminal by using the location information of the calling IP terminal and the location information of the called IP terminal; A fourth step of displaying a talk time between the calling IP terminal and the called IP terminal; And a fifth process of calculating a fee for the call by using the distance calculated in the third process and a rate set for the distance when the call between the calling IP terminal and the called IP terminal is terminated. It features.

Preferably, the fourth process of the present invention is a 4-1 process of starting the call time display when a confirmation message is received from the originating IP terminal; And a step 4-2 of terminating the call time clock when a termination message is transmitted from the calling IP terminal or the called IP terminal.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a broadband integrated network to which a location-based fee calculation method according to an embodiment of the present invention is applied.

As shown in FIG. 1, the broadband converged network includes an IP-PBX 10 for providing an internal call service and an external call service by connecting a plurality of IP terminals 2 and 4, and a plurality of IP-PBXs 10,. ...) or a plurality of IP terminals (6, 8, ...) are directly connected to the call processing server 20 for performing a call processing procedure for session connection to the connected IP terminal.

Typically, when a call connection request is input from the subscriber of the originating IP terminal, the originating IP terminal transmits an INVITE message, which is a start message, to the call processing server 20, and the call processing server 20 receives the incoming IP terminal from the INVITE message. The information is extracted and the call processing procedure between the calling IP terminal and the called IP terminal is performed.

In general, the INVITE message transmitted from the originating IP terminal is as follows.

The INVITE message is a SIP message that is output from a terminal that the terminal does not have a location information providing function.

On the other hand, the IP terminals (2, 4, 6, 8) of the present invention is characterized in that the location information providing function.

In the embodiment of the present invention, the IP terminals 2, 4, 6, and 8 are equipped with a Global Positioning System (GPS) function, and after generating their own location information, the location information is included in the SIP message and the call processing server ( 20), so that the call processing server 20 can provide a predetermined application service based on the location information of each IP terminal (2, 4, 6, 8).

However, unlike this case, the user of the IP terminal (2, 4, 6, 8) may be configured to input the location information separately.

FIG. 2 is a signal flow diagram illustrating a call processing procedure of a SIP call to which a location-based fee estimation method is applied in a broadband converged network according to an embodiment of the present invention.

When the user of the originating IP terminal 2 requests a telephone call, the originating IP terminal 2 generates an INVITE message based on the SIP protocol and transmits it to the call processing server 20 (S1).

The INVITE message transmitted from the originating IP terminal 2 is as follows.

The INVITE message includes latitude information and longitude information.

The call processing server 20 transmits the INVITE message to the destination IP terminal 6 (S2) and extracts the location information of the originating IP terminal 2 from the INVITE message.

The destination IP terminal 6 receiving the INVITE message outputs a ring signal, and also transmits a 180 message (acknowledgment message) including its location information to the call processing server 20 (S3).

The call processing server 20 transmits the 180 message to the calling terminal 2 and extracts the location information of the destination IP terminal 6 from the 180 message.

In this state, when the user of the destination IP terminal 6 receives a call, the destination IP terminal 6 transmits 200 messages to the call processing server 20 (S5), and the call processing server 20 transmits the 200 messages. To transmit to the calling IP terminal 2 (S6).

Subsequently, the originating IP terminal 2 transmits an ACK message (confirmation message) to the call processing server 20 (S7), and the call processing server 20 transmits the ACK message to the destination IP terminal 6 ( According to S8), a real time transport protocol (RTP) session is connected between the source IP terminal 2 and the destination IP terminal 6 so that the source IP terminal 2 and the destination IP terminal 6 can perform a telephone call. do.
