More specifically, the routing manager 420 manages traffic routing information for the subscriber device 100 by mapping the subscriber device 100 with the device identification information (e.g., IMSI) of the subscriber device 100, It is preferable to manage the traffic classification information for each data traffic for the network 100.

Based on the request from the subscriber unit 100 or the network selection policy from the specific policy management device 600, the routing management unit 420 determines, based on the network selection policy for the specific data traffic generated in response to the specific subscriber device 100, It is possible to generate traffic routing information for the subscriber device 100 by setting up distribution ratio information for each network corresponding to two or more networks.

That is, the routing management unit 420 distributes / transmits traffic for two or more networks (e.g., 3G, WiFi) for specific data traffic corresponding to the subscriber device 100 according to a request from the specific subscriber device 100 The distribution ratio can be determined. Alternatively, the routing management unit 420 may consider the location of the subscriber device 100, the service type of this data traffic (e.g., e-mail service), and the like based on the predefined network selection policy provided from the policy management apparatus 600 It is possible to determine the distribution ratio of distributing / transmitting traffic for two or more networks (e.g., 3G, WiFi).

More specifically, the routing management unit 420 manages traffic distribution information for each network in correspondence with traffic classification information for each data traffic for the subscriber device 100 in managing traffic routing information for the subscriber device 100 .

Accordingly, the routing manager 420 manages the routing information of each subscriber device registered to use the simultaneous transmission service, for example, the first network mapped on the basis of the device identification information (e.g., IMSI) of each subscriber device, Destination IP, Destination Port, Protocol (UDP, IP), traffic information for each network including connection information (e.g., 3G IP and WiFi IP), virtual network connection information TCP, etc.) information, traffic classification information for each data traffic, and distribution ratio information for each network, which indicates the distribution ratio for each 3G network and WiFi network.

The traffic routing information for each subscriber unit for the downlink data traffic managed by the routing management unit 420 may have a form as shown in FIG.

That is, as shown in FIG. 3, the traffic routing information for each subscriber device includes an area (a) for recording device identification information of each subscriber device, an area (b) for recording connection information for each network of each subscriber device, An area (c) for recording traffic classification information for each data traffic of the apparatus, and an area (d) for recording distribution ratio information for each network of each data traffic.

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

The routing manager 420 precisely divides the transmission target data according to the concurrent transmission service into traffic based on the traffic routing information for each subscriber device and traffic of a certain type of service, A determination is made as to which distribution rate the partial data of the transmission target data according to the divided data traffic should be transmitted through two or more networks.

More specifically, the routing management unit 420 determines at least one of the transmission destination information, the destination connection information, and the destination port information including at least one of the source connection information and the source port information from the transmission target data to be provided to the subscriber device Recognizing the destination information including any one of the first traffic information and the second traffic information, and based on the previously registered traffic classification information of the traffic routing information, recognizes corresponding data traffic for a specific subscriber device having at least one of the recognized destination information and the destination information And divides the transmission target data into the perceived data traffic.

That is, when receiving the downlink transmission object data generated according to the simultaneous transmission service from the external device 500, the routing management unit 420 recognizes at least one of the source connection information and the source port information in the header of the corresponding data And recognize at least one of the destination connection information and the destination port information.

In other words, the routing management unit 420 recognizes the source connection information and the source port information, that is, the IP and Port of the external device 500, in the header of the downlink transmission object data, and stores the destination connection information corresponding to the destination, It is possible to recognize the destination port information, that is, the virtual IP and Port of the specific subscriber device 100.

The IP and Port of the external device 500 recognized in the current downlink transmission object data among these traffic classification information are connected to the source It is possible to retrieve the traffic classification information as connection information and source port information.

When one traffic classification information is searched through the search as described above, the routing management unit 420 recognizes that the downlink transmission target data is the traffic according to the searched traffic classification information, Data traffic according to the service can be distinguished.

Accordingly, the routing manager 420 can identify / extract two or more network-based distribution ratios corresponding to the separated data traffic based on the predetermined network-specific distribution ratio information of the traffic routing information.

That is, when the routing management unit 420 identifies the data traffic by searching for the traffic classification information corresponding to the downlink data traffic received from the external device 500, the routing management unit 420 searches the traffic classification information (For example, 3G - 50%, WiFi - 50%) recorded / registered in correspondence with each other.

The routing processor 430 divides the data to be transmitted into two or more partial data and transmits the partial data to the corresponding network in accordance with the determined distribution ratio for two or more networks.

At this time, the routing processing unit 430 may perform the data traffic classification and the distribution ratio determination performed by the routing management unit 420, not the routing management unit 420.

That is, the routing processor 430 recognizes the transmission destination information and the destination information in the transmission target data, and matches the transmission destination information and the destination information to at least one of the recognized transmission destination information and the destination information based on the traffic classification information included in the traffic routing information It is possible to identify the data traffic and to divide the transmission target data into the confirmed data traffic.

When the data traffic is classified as described above, the routing processor 430 divides the recorded / registered network share ratio information (eg, 3G - 50%, WiFi - 50%) corresponding to the traffic classification information currently searched in the traffic routing information, ).

Accordingly, the routing processing unit 430 divides the transmission object data into two or more partial data, divides the distribution rate for each of the two or more networks corresponding to the identified data traffic into which the transmission object data is divided from the distribution rate information for each network as described above And may transmit the partial data on two or more networks (e.g., 3G, WiFi) according to the identified distribution ratio of two or more networks.

That is, the routing processor 430 determines network connection information (e.g., subscriber unit 3G IP, subscriber unit WiFi, etc.) for the specific subscriber unit 100 corresponding to the separated data traffic based on network- IP) and virtual network connection information (e.g., virtual IP).

Then, the routing processing unit 430 divides the downlink transmission object data received from the external apparatus 500 into two or more partial data.

The routing processing unit 430 transmits the network connection information (e.g., subscriber unit 3G IP, subscriber unit WiFi IP) for the subscriber unit 100 acquired in accordance with the data traffic classification in the routing management unit 420, Based on the connection information (e.g., virtual IP), the network-corresponding connection information and the virtual network connection information to be transmitted are included in each partial data. For example, the routing processor 430 may include the subscriber unit 3G IP and the virtual IP in the partial data to be transmitted to the 3G network, and may include the subscriber unit WiFi IP and the virtual IP in the partial data to be transmitted to the WiFi network .

The routing processor 430 then transmits the respective partial data described above to the corresponding routing information based on the distribution rate information (for example, 3G - 50%, WiFi - 50%) for each network identified according to the data traffic classification in the routing management unit 420 (For example, 3G, WiFi) so that the specific subscriber device 100 can receive it.
