Thus, the traffic routing information for the subscriber device 100 having IMSI-45005 11111 11111 will be described as an example. In the area (a), the IMSI-45005 11111 11111 of the subscriber device 100 is recorded, and in the area (b). As access information for each network corresponding to the subscriber device 100, the subscriber device 3G IP, the subscriber device WiFi IP, and the virtual IP may be recorded. Further, in the area (c), the traffic classification information of each of the plurality of data traffics 1, 2, and 3 generated corresponding to the subscriber device 100 is recorded. For example, considering downlink data traffics 1, 2, and 3, The IP of the external device 500 corresponding to each data traffic may be recorded as the source IP, and the corresponding port of the external device 500 may be recorded in the area c as the source port. In the area (d), distribution rate information for each network corresponding to the subscriber apparatus 100, for example, 3G-00% for the data traffic 1 and 100% for WiFi-is recorded, and the data traffic 2 is recorded in the data traffic 2. 3G-100%, WiFi-0%, and 3G-50%, WiFi-50%) for data traffic 3 can be recorded.

It is possible to retrieve the traffic classification information which has the connection information and the source port information.

When one piece of traffic classification information is searched through the search as described above, the routing management unit 420 recognizes that the downlink transmission target data is traffic according to the retrieved traffic classification information, thereby identifying a specific subscriber device 100. It can be distinguished that it is data traffic according to service.

Accordingly, the routing manager 420 may identify / extract distribution ratios of two or more networks corresponding to the divided data traffic based on preset distribution ratio information for each network of the traffic routing information.

That is, when the routing management unit 420 classifies the data traffic as described above by searching the corresponding traffic classification information for the downlink data traffic received from the external device 500, the routing management unit 420 is applied to the traffic classification information retrieved from the traffic routing information. Correspondingly, distribution rate information for each network recorded / registered (eg 3G-50%, WiFi-50%) can be checked.

The routing processor 430 divides the transmission target data into two or more partial data, and transmits each partial data to the corresponding network according to the determined distribution ratio for each of the two or more networks.

In this case, the data traffic classification and distribution rate determination performed by the routing manager 420 may be performed by the routing processor 430 instead of the routing manager 420.
