And, wherein the DHCP server uses the option field in the DHCP request message transmitted from the media processing boards to determine where the media boards are located in the network.

Resource management method of a media gateway using a DHCP server according to the present invention for solving the above technical problem is a gateway resource management method in an all-IP based mobile communication network, (a) a media processing board mounted on a media gateway Transmitting a DHCP request signal to a DHCP server; (b) the DHCP server identifying the location information of the board with the DHCP request signal requested from the media processing board of the gateway; (c) finding the designated IP by searching the resource management database after the DHCP server grasps the location information; (d) assigning, by the DHCP server, the designated IP to the media processing board of the gateway; And (e) reporting the status to the call agent (CA) after the media processing board of the gateway completes its initialization.

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

1 is a block diagram of a resource management system of a media gateway using a DHCP server according to the present invention. The main components include a mobile communication switch 10, a mobile telephone base station 20, a media gateway 30, It consists of a call agent 40, a DHCP server 50 and a database 60.

The mobile communication switch (MSC: 10) functions as a central control to process signals received and received from each mobile communication base station 20 and to adjust the mobile communication base station 20 to be efficiently operated.

In addition, a mobile communication switch (MSC) using a standard telephone signal serves to control a radio link and a wire link, and to connect a mobile communication terminal and a mobile communication base station 20 or another communication network.

In addition, the mobile communication switch (MSC: 10) manages the location of the mobile communication terminal and queries the home subscriber location register (HLR) for the user's location registration information.

The mobile communication base station 20 is responsible for a wireless transmission and reception function, mainly responsible for transmission and reception with the mobile communication terminal.

The media gateway 30 has a media processing board 35 for transmitting and receiving media traffic to and from the mobile communication base station 20 in the mobile communication exchange (MSC: 10) and the ALL-IP mobile communication network.

The call agent 40 is responsible for call processing in an ALL-IP mobile communication network, and includes a DHCP server 50 and a database 60.

The dynamic host deployment protocol (DHCP) server 50 processes the DHCP request signal transmitted from the media processing board 35 mounted on the media gateway 30.

The database 60 has resource management setting information such as an assigned IP address of the media processing board 35, channel mapping table information with the mobile communication switch 10, and the like.

According to the above-described configuration, the DHCP server 50 can use the option field in the DHCP request message transmitted from the media processing boards 35 to determine where the boards are located in the network. The option used here is a DHCP server that receives a DHCP request signal by passing the gateway ID and the geographical ID (generally the slot ID) in the media gateway 30 using the "Vender Specific Information Option" ( 50) to identify the location.

The location information thus obtained is searched for the database 60 in which the resource management setting information is stored, and the designated IP address is assigned to the media processing board 35.

That is, in the present invention, by grasping the location information of the media processing board 35 mounted on the media gateway 30 through DHCP, the mobile communication exchanger may not have an intelligent CPU board for resource management in the media gateway 30 itself. MSC: 10) can support channel resource mapping.

In addition, a media gateway 30 independent of a call agent (CA) 40 may be configured in a mobile communication network based on ALL-IP.

2 is a flowchart illustrating a resource management method of a media gateway using a DHCP server according to the present invention.

First, the media processing board 35 mounted on the media gateway 30 transmits a DHCP request signal to the DHCP server 40 (S210).

Here, the media processing board 35 is mounted in the media gateway 30 to transmit and receive media traffic with the mobile communication base station 20 in the mobile communication exchange (MSC: 10) and the ALL-IP mobile communication network. .

The DHCP server 50 determines the location information of the board with the DHCP request signal requested from the media processing board 35 of the media gateway 30 (S220).

Here, an option field in a DHCP request message transmitted from the media processing boards 35 is used, and the option used here is a gateway ID and a geographic image in the media gateway 30 using a "Vender Specific Information Option". By passing a geographical ID (generally a slot ID), the DHCP server 50 receiving the DHCP request signal can determine the location.

After the DHCP server 50 grasps the location information, the DHCP server 50 searches the resource management database 60 to find a specified IP (S230).

The DHCP server 50 assigns the designated IP to the media processing board 35 of the media gateway 30 (S240).

The media processing board 35 of the media gateway 30 finishes its initialization and reports a status to the call agent CA 40 (S250).

Here, the call agent (CA) 40 and the media gateway 30 may be configured independently in a mobile communication network based on ALL-IP.

As described above, the present invention has been described with reference to the embodiments illustrated in the drawings, which are merely exemplary, and it should be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

According to the present invention, it is possible to support channel resource mapping with a mobile communication exchange (MSC) without having an intelligent CPU board for resource management separately in the media gateway itself, and the media gateway itself may be composed of only boards having a media processing function. There is an advantage that the configuration is simplified.

In addition, since a media gateway independent of a call agent (CA) can be configured in a mobile communication network based on ALL-IP, the versatility of the media gateway can be greatly increased.
