That is, one channel selected by the user from among the plurality of DMB channels is selected, and only DMB data corresponding to the channel is output.

The DMB data processor 370 converts the DMB data transmitted from the DMB channel selector 360 into a form (for example, an IP packet) for transmitting to the wireless network. The result is then transferred to the switch 330. Then, the switch 330 controls the controller 320 to transmit the DMB data transmitted from the DMB data processor 370 only when the corresponding user is approved based on the authentication result of the user transmitted from the physical layer I / F unit 340.

FIG. 6 is a flowchart illustrating a process for providing a DMB service using a wireless communication network according to an embodiment of the present invention, and includes a wireless communication network access device including a DMB processor ('AP' of a WLAN or 'MSS of a WMAN'). ') Illustrates a process for providing a DMB service. 5 and 6, a process for providing a DMB service using a wireless communication network according to an embodiment of the present invention is as follows.                     

First, the access device of the wireless communication network (hereinafter referred to as "AP") receives DMB data of all channels (S205). That is, the AP receives DMB data of all channels transmitted from the DMB data transmitter or the DMB data providing server. It waits for the DMB data request message to be received from the terminal. As a result, when a DMB data request message including channel information and user information of the DMB is received from the terminal (S210), the AP analyzes the DMB data request message (S215) and then the user information and channel information from the DMB data request message. To extract (S220).

An example of a message structure for the DMB data request message transmitted from the terminal to the AP in step S210 is shown in FIG. 7A. Referring to FIG. 7A, the DMB data request message 510 includes address information (addr.) 511 of a terminal, address information (addr.) 512 of an AP to which the message is transmitted, and channel information 513 selected by a user. It includes.

Meanwhile, in step S220, the AP extracts user information and channel information of the user who requested the DMB data and selects a DMB channel to receive the DMB data based on the channel information (S225). In operation S230, the DMB data of the selected channel is processed. That is, in order to deliver the DMB data of the selected channel to the terminal 200, the DMB data is converted into a form (for example, an IP packet) that can be delivered in a wireless communication network.

In addition, the AP performs user authentication based on the user information included in the DMB data request message (S235). To this end, the AP transmits the user information to an external authentication server (AAA server) so that the authentication server checks whether the user can use the DMB service (S240). If it is determined in step S240 that the user can use the DMB service, the AP transmits the DMB data to the terminal requesting the DMB data (S245). On the other hand, if the user cannot use the DMB service as a result of the check (S240), the AP immediately terminates without performing the process (S245).

At this time, an example of a message structure for the DMB data transmitted from the AP to the UE in step S245 is shown in FIG. 7B. Referring to FIG. 7B, the DMB data 520 may include address information (addr.) 521 of an AP, address information (addr.) 522 of a terminal to which DMB data is to be transmitted, and DMB data 523 in an IP packet form.
