In this case, the first to nth relay apparatuses 210, 220, and 230 may perform deregistration and disconnection reporting of the multiple communication terminal device 300. In addition, the connection information management unit 160 of the heterogeneous convergence communication server 100 stores the connection information of the multi-communication terminal device 300 when the multi-access registration unit 110 receives the multi-communication connection of the multi-communication terminal device 300. And manage. Hereinafter, a case in which the heterogeneous communication server 100 is connected through the first relay device 210 and the second relay device 220 will be described as an example to help understand the description.

Then, the multi-communication control unit 320 of the multi-communication terminal device 300 uses heterogeneous convergence communication using one or a plurality of relay devices among the first to n-th relay devices 210, 220, 230 according to the registration of the multi-communication connection. Set up the environment. For example, a heterogeneous convergence communication environment for transmitting and receiving data with the heterogeneous convergence communication server 100 may be set through the first relay device 210 and the second relay device 220 (S503).

Meanwhile, referring to FIG. 4, the multiple access registration unit 110 of the heterogeneous convergence communication server 100 may be one or a plurality of first to nth relay devices 210, 220, and 230 under the control of the convergence communication control unit 130. Multiple communication connection of the multiple communication terminal device 300 connected to the multiple access through the relay device of the registration. For example, the multi-communication connection of the multi-communication terminal device 300 connected to the multi-connection via the first relay device 210 and the second relay device 220 may be registered (S401). In this case, the connection information management unit 160 of the heterogeneous convergence communication server 100 stores and manages connection information of the multi-communication terminal device 300.

Then, the fusion communication control unit 130 of the heterogeneous fusion communication server 100 uses heterogeneous fusion communication using one or a plurality of relay devices among the first to nth relay devices 210, 220, and 230 according to the registration of the multiple communication connection. Set up the environment. For example, a heterogeneous convergence communication environment for transmitting and receiving data with the multiple communication terminal device 300 may be set through the first relay device 210 and the second relay device 220 (S403).

The heterogeneous fusion support unit 120 of the heterogeneous fusion communication server 100 determines the parallel transmission ratio of data through the first to nth relay devices 210, 220, and 230 according to the configuration of the heterogeneous fusion communication environment. For example, the parallel transmission ratio for transmitting data in parallel through the first relay device 210 and the second relay device 220 may be determined. That is, when the ratio of data to be transmitted through the first relay device 210 is m and the ratio of data to be transmitted by the second relay device 220 is k, the parallel transmission ratio “m: k” can be determined. There is (S405).

Subsequently, the data distribution unit 140 of the heterogeneous fusion communication server 100 operates under the control of the fusion communication control unit 130 to distribute data to n pieces according to the previously determined parallel transmission ratio (S407), and the data transmission unit ( 150 transmits n pieces of data distributed in parallel through a plurality of relay devices among the first to nth relay devices 210, 220, and 230 according to a heterogeneous convergence communication environment under the control of the converged communication control unit 130. . For example, data may be transmitted in parallel at a ratio of m: k through the first relay device 210 and the second relay device 220 (S409).

Referring to FIG. 5 again, the data combination unit 330 of the multi-communication terminal device 300 may control a plurality of relays among the first to n-th relay devices 210, 220, and 230 under the control of the multi-communication control unit 320. Parallel data transmitted through the device is received according to a heterogeneous convergence communication environment (S505), and the received parallel data are combined and serialized. For example, parallel data received from the heterogeneous converged communication server 100 through the first relay device 210 and the second relay device 220 may be combined and serialized (S507).

Referring to FIG. 4, when the connection environment of the multiple communication terminal device 300 to which the multiple access registration unit 110 is registered is changed (S411), the fusion communication control unit 130 of the heterogeneous convergence communication server 100 transmits data to be transmitted. Is left (S415), the heterogeneous fusion communication environment is set again, and the heterogeneous fusion support unit 120 controls to determine the parallel transmission ratio again.

Accordingly, when the heterogeneous fusion support unit 120 determines the parallel transmission rate again, the data distribution unit 140 distributes the data based on the determined parallel transmission rate again, and the distributed data is divided according to the data transmission unit 150. It is transmitted to the multi-communication terminal device 300 through the relay device (S413).

Meanwhile, the data transmitted by the heterogeneous fusion communication server 100 to the multi-communication terminal device 300 may be data generated or stored by the heterogeneous fusion communication server 100, and may be a music file server 10 or an additional service server. It may be data received from the (20). For example, upload data from the multi-communication terminal device 300 to the heterogeneous convergence communication server 100, the music file server 10, or the additional service server 20 may be transmitted from the first to nth relay devices 210, 220, and 230. The packetized packet may be transmitted to the music file server 10 or the additional service server 20 with authorized connection information (eg, an internet protocol address) of the relay device, and the music file server 10 or the additional service server 20 may be transmitted. The download data from the multi-communication terminal device 300 to the heterogeneous communication server 100 may find and transmit a corresponding multi-communication terminal device 300 based on the access information (eg, caller ID) included in the packet. .

In addition, according to the embodiment of FIG. 1A, the multi-communication terminal device 300 may use the music file server 10 through one of the first to nth relay devices 210, 220, and 230, for example, to download the music file. ) Can be requested to download the file, and the relay device used can be selected by the user when requesting the file download based on a predetermined priority. In this case, since the heterogeneous communication server 100 may distinguish packets transmitted by the first to nth relay devices 210, 220, and 230, the heterogeneous communication server 100 may bypass the packet when the multiple communication terminal device 300 does not transmit the packet. When the signal transmission is performed in a general manner, but the packet is transmitted by the multi-communication terminal device 300, the music file server 10 requests the file transmission, but from the viewpoint of the music file server 10, a heterogeneous convergence communication server ( 100 is requested to be viewed as the final transmission target of the file, and the received file is distributed to the first to nth relay apparatuses 210, 220, and 230 to be transmitted to the multiple communication terminal device 300.

Alternatively, according to the embodiment of FIG. 1B, when the multi-communication terminal device 300 requests the music file while informing the heterogeneous communication server 100 of the music file server 10 to download the music file, for example, the heterogeneous convergence communication device 300 may receive heterogeneous convergence. The communication server 100 may request the music file server 10 to transmit the music file. In this case, the relay device used may be selected by the user when requesting a file download based on a preset priority. Then, the music file server 10 recognizes the heterogeneous fusion communication server 100 as the multi-communication terminal device 300 when transmitting the file, that is, the heterogeneous fusion communication server 100 is recognized as the final transmission target of the file. In one state, the file requested by the multi-communication terminal device 300 may be transmitted.

In addition, when transmitting a packet from the music file server 10 or the additional service server 20 to the multi-communication terminal device 300, the heterogeneous communication server 100 resets the access information included in the received packet and multi-communication. The terminal device 300 may transmit to the connected relay device.
