As shown in FIG. 1, a communication network access management system according to an embodiment of the present invention includes a location register 600, a gateway node 500, access gateways 400-1 and 400-2, and a first type access device 200. -1, 200-2 and type 2 access devices 300-1, 300-2, 300-3, and 300-4, and are connected to the mobile terminal 100 by a wireless link to perform data transmission and reception. .

The location register 600 may provide shape information about two or more networks having different standards from profile information of the mobile terminal 100 (in an embodiment of the present invention, cellular and WLAN networks). Save it. Here, the shape information is topology information, and includes location information on each network component (access device) of the cellular network and the wireless LAN and neighbor device information between each network device (access device).

Specifically, the location register 600 may include the first type access devices 200-1 and 200-2 of the cellular network and the second type access devices 300-1, 300-2, 300-3, and the like of the WLAN. 300-4 pre-stores neighbor device information belonging to the mutual mobile terminal access area (coverage).

In addition, the location register 600 is a mobile terminal 100 from the first type access device (200-1, 200-2) and the second type access device (300-1, 300-2, 300-3, 300-4). ), And stores the location information of the access device to which the mobile terminal 100 is connected.

In addition, the location register 600 stores and manages profile information including MAC information and subscriber information of the mobile terminal 100.

The gateway node 500 transmits data received from the other network to the corresponding access gateways 400-1 and 400-2, or transmits data received from the access gateways 400-1 and 400-2 to the other network. Perform the function.

The access gateways 400-1 and 400-2 are connected to the gateway node 500 and the location register 600 to perform data transmission and reception, and fuse data received from access devices of different networks.

In addition, the access gateways 400-1 and 400-2 are in charge of subscriber mobility management and session management functions, and access devices 200-1 and 200 of different networks connected through interworking with the location register 600. -2, 300-1, 300-2, 300-3, 300-4 to store and manage the shape information.

In addition, the access gateways 400-1 and 400-2 control network connection of the mobile terminal 100 based on the data format of data received from another network and the location information of the mobile terminal. At this time, the format of the data refers to the standard of the data (standard such as 802.11b).

In detail, when the access gateways 400-1 and 400-2 receive data from another network, the access gateways 400-1 and 400-2 provide the received data with the format of the location register 100 to provide the received data to the mobile terminal 100. If one of a plurality of networks (cellular network or wireless LAN in the embodiment of the present invention) is selected based on the mobile terminal location information, and the mobile terminal 100 is not connected to the selected network, heterogeneous of the mobile terminal Control network access.

For example, when receiving data of a wireless LAN, a wireless LAN for transmitting data to a mobile terminal is selected from among a plurality of networks based on the data format and location information of the mobile terminal, and the network to which the mobile terminal is connected. If the mobile terminal is connected to the cellular network instead of the WLAN after checking, Paging is requested to connect the mobile terminal to the WLAN through the cellular network.

The first type access devices 200-1 and 200-2 are access terminals of the cellular network, and control the mobile terminal device 100 to access the cellular network. For example, it is a base station of a cellular network.

In this case, the mobile terminal 100 accesses the selected type 1 access device 200-1 and deactivates an interface not used for power saving. For example, if the user accesses the first type access device 200-1, the interface for the WLAN connection is deactivated in order to save power of the mobile terminal 100.

The first type access device 200-1 receives a location registration request message from the mobile terminal 100, and includes the information of the first type access device 200-1 in the location registration request message to access gateway 400-. 1) (S106).

The access gateway 400-1 sends a location registration request message received from the type 1 access device 200-1 to the location register 600 to record the location of the mobile terminal 100 (S108). The user profile and the service profile which are user information stored in the register 600 are received (S110).
