This will be described.

First, in order to use the data simultaneous transmission service in a heterogeneous network environment, a service registration procedure between the terminal device 100 and the management device 400 must be preceded.

In this regard, the terminal device 100 receives its first network access information (eg, 3G IP) for the 3G network and assigns its second network access information (eg, WiFi IP) for the WiFi network. Will receive.

For example, each of the first network device 200 and the second network device 300 may include a specific address allocating device for allocating the same network access information according to a preset interworking policy with a specific other network device 300 or 200. For example, network connection information corresponding to a specific transmission device, that is, the terminal device 100, may be allocated from the common DHCP, and the allocated network connection information may be allocated to the terminal device 100.

Thus, the first network device 200 of the 3G network and the second network device 300 of the WiFi network are assigned to the same network connection information to one transmitting device, that is, the terminal device 100 (for example: By receiving network connection information (first network access information (eg, 3G IP) and second network connection information (eg, WiFi IP)) for the terminal device 100 from the common DHCP), the terminal device 100 is provided to the terminal device 100. In addition, the first network access information (eg, 3G IP) and the second network access information (eg, WiFi IP) allocated from the terminal device 100 will be identical to each other.

Accordingly, the management device 400 may indicate additional information included in the service registration request, for example, device identification information (for example, IMSI), first network access information (for example, 3G IP), and a network indicating a network type for sending a binding update message. Check the type information (eg 3G) and service classification information (Initial, Update, Remove) to perform service registration for the terminal device 100 and send a binding update response message (Binding Update Ack) to the terminal device 100. By replying, a service registration procedure via the 3G network can be performed.

In addition, the terminal device 100 accesses the management device 400 through the second network, that is, the WiFi network, and updates the binding based on the obtained access information (eg, management device WiFi IP) of the management device 400 for accessing the WiFi network. By sending a message (Binding Update) requests the service registration for the terminal device 100 itself. Accordingly, the management device 400 may indicate additional information included in the service registration request, for example, device identification information (for example, IMSI), second network access information (for example, WiFi IP), and a network indicating a network type for sending a binding update message. Check the type information (for example, WiFi) and service classification information (Initial, Update, Remove) to perform service registration for the terminal device 100 and return a binding update response message (Binding Update Ack) to the terminal device 100. As a result, a service registration procedure through the WiFi network may be performed.

As described above, when all procedures for registering a service between the terminal device 100 and the management device 400 are completed, a heterogeneous network, that is, a 3G network and a WiFi, transmits and receives data between the terminal device 100 and the external device 500. A simultaneous transmission service over the network will be initiated.

First, the terminal apparatus 100 will be described based on an uplink procedure of transmitting data to the management apparatus 400 as a receiving apparatus as a transmitting apparatus.

The terminal device 100 divides the transmission target data into partial data to use the simultaneous transmission service.
