The present invention relates to a method for providing an emergency call service in a broadband integrated network, and more particularly, an emergency call service requested from the IP terminal based on the location of the IP terminal by detecting a geopolitical location of the IP terminal in the broadband integrated network. It relates to a technology that can provide.

The Public Switched Telephone Network (PSTN), which provides telephone service for landline telephones, stores the installation location for each telephone number so that the operator can easily identify the location information of the telephone user.

In addition, even in a mobile communication network that provides a phone service for a mobile phone, since the location information of the mobile phone is stored in the VLR (Visitor Location Register) whenever the mobile phone moves, the service provider can easily locate the telephone user. Can be identified.

However, although the IP terminal having an IP address using the IP address has an IP address, since the IP address does not mean a geopolitical location, it is difficult for a service provider to accurately determine the location of the IP terminal. . For this reason, there is a problem in the broadband integrated network can not provide an emergency call service provided based on the geopolitical location of the call terminal.

For reference, the emergency call service recognizes an emergency call when a user inputs a phone number specially designated for emergency call, for example, "119", "112", or a specific number key, for example, "#", "*". By connecting the call to the relevant organization (eg, fire station, police station, hospital, etc.) that is located closest to the location of the call requester, the agency can quickly respond to the emergency situation of the call requester.

The emergency call service needs to search for the corresponding agency based on the geopolitical location of the call requester, that is, the terminal requesting the emergency call, so that the corresponding agency can quickly cope with the emergency situation of the call requester through dispatch.

The present invention has been made in view of the above circumstances, and the present invention is to detect the geopolitical location of the IP terminal in the broadband integrated network to provide the emergency call service requested from the IP terminal based on the location of the IP terminal It is for that purpose.

In order to achieve the above object, the emergency call service providing method in the broadband integrated network according to the present invention, when the start message is received from the IP terminal, by analyzing the start message to determine whether the call is an emergency call call; process; A second step of extracting location information of the IP terminal from the start message if the call is an emergency call; A third step of searching for the nearest emergency call officer based on the location of the IP terminal by searching the emergency call officer information registered in advance based on the evicted location information; And a fourth process of transmitting the start message to the retrieved emergency call agency terminal and connecting the emergency call.

Preferably, in the present invention, the IP terminal is equipped with a GPS function, characterized in that the transmission including the GPS location information in the start message.

Preferably, in the present invention, the IP terminal is characterized by transmitting the location information directly input from the user in the start message.

Preferably, in the present invention, the start message is characterized in that the SIP protocol based INVITE message.

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 an emergency call service providing method according to an exemplary embodiment of the present invention is applied.

As shown in FIG. 1, an IP terminal 10 performing a VoIP function or the like is connected to the broadband integrated network 20, and the broadband integrated network 20 has a call processing function for the IP terminals 10... A call processing server 22 for performing the above is provided. In particular, the call processing server 22 of the present invention is provided with information (eg, processable emergency call information, location information, phone number information, etc.) of an organization for emergency call support for each region, and is provided from the IP terminal 10. When an emergency call is generated, a call connection request is performed to a terminal of an organization in which the IP terminal 10 is closest to, for example, the IP terminal 30, based on the geographical position of the IP terminal 10.

In particular, the IP terminal 10 applied to the present invention is equipped with a GPS function to generate its own geographic location information, and the SIP protocol based INVITE message, which is a start message to the broadband integrated network 20 for call origination. When transmitting, the location information is included and transmitted.

If the GPS terminal is not equipped with the GPS function, the IP terminal 10 may generate geographical location information using information directly input from the user.

On the other hand, a typical INVITE message that does not include location information is as follows.

On the other hand, the INVITE message transmitted from the IP terminal 10 of the present invention is as follows.

As described above, in the present invention, the INVITE message transmitted from the IP terminal 10 includes latitude information and longitude information.

Next, an emergency call service providing method in a broadband converged network according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 2.

When the INVITE message is received from the IP terminal 10, the call processing server 22 determines whether the SIP call according to the INVITE message is an emergency call by analyzing the called number included in the INVITE message (S4). Here, the emergency call may be "119", "112" and the like.

As a result of analyzing the called number in step S4, if it is determined that the SIP call is not an emergency call call (No in S4), the call processing server 22 sends the INVITE to the IP terminal corresponding to the called number included in the INVITE message. The message is transmitted to enable a real time transport protocol (RTP) voice call between the calling IP terminal 10 and the called IP terminal (S6).

On the other hand, when analyzing the called number in step S4, if it is determined that the SIP call is an emergency call call (Yes in S4), the call processing server 22 from the INVITE message to the location information of the IP terminal 10 (latitude / Longitude information), and retrieves the engine information stored in advance based on the extracted position information, and retrieves the engine information closest to the geopolitical position of the IP terminal 10 (S10).

Subsequently, the call processing server 22 transmits the INVITE message to the searched IP terminal of the institution to enable an RTP voice call between the IP terminal 10 and the institution IP terminal 30 (S12).

As described above, the emergency call service providing method in the broadband integrated network according to the embodiment of the present invention has an effect of providing an emergency call service based on the geopolitical location of an IP terminal using an IP address.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
