To this end, the target selection unit 610 collects respective network load ratio information from the first network device 200 and the second network device 300 to which the terminal device 100 is connected, and the subscriber management device 700 And collects the determination information including the cumulative traffic usage amount per subscriber from the data management apparatus 800, and combines the collected determination information to perform per-subscriber traffic analysis.

Then, the policy application target is selected based on the traffic analysis result of each subscriber (S330).

Preferably, the object selecting unit 610 selects a policy application target through traffic analysis by the subscriber, thereby providing a network selection policy for one or more terminal devices corresponding to the selected policy application target. In other words, the target selection unit 610 performs traffic analysis for each subscriber based on various determination information criteria including, for example, the load ratio of each subscriber-specific access network, subscriber-specific rate plan, and traffic usage per subscriber, It is possible to select one or more terminal devices corresponding to the policy application target by checking whether the reference state is exceeded. At this time, the target selection unit 610 confirms whether the base station state of the analyzed traffic state of the subscriber is exceeded. For example, if the load rate of the access network is 50% or more, the specific rate plan registered, The device is selected as a policy application target.

Next, a priority is set for the policy application target (S340).

Preferably, the object selection unit 610 assigns a priority to the plurality of terminal devices selected as the object of policy application according to the degree of exceedance of the reference state of the analyzed traffic state, so that the network selection policy So that they can be provided sequentially.

Then, a network selection policy is determined for one or more terminal devices corresponding to the selected policy application target (S350).

Preferably, the policy decision unit 620 determines the policy of the terminal device 100 and the management thereof according to various network parameters on the heterogeneous network and network conditions, including, for example, subscriber preference, subscriber type, subscription plan, A relative utilization ratio between networks is included so that data to be transmitted can be divided to correspond to the number of networks for simultaneous transmission of data using heterogeneous network environments, that is, 3G networks and WiFi networks, based on network status information received from the device 400 To determine the network selection policy.

Thereafter, the determined network selection policy is provided (S360-S370).

Preferably, the policy providing unit 630 provides the network selection policy only to one or more terminal devices corresponding to the policy application target, by checking the selected policy application target when providing the network selection policy. At this time, the policy providing unit 630 sequentially transmits the network selection policies determined according to the priorities assigned to the policy application targets, thereby allowing the corresponding terminal device 100 to set the relative usage rates of the 3G network and the WiFi network to, for example, 3G Network 10% and WiFi network 90%, 3G network 90% and WiFi network 10%, 3G network 50% and WiFi network 50%, 3G network 100% and WiFi network 0%, 3G network 0% and WiFi network 100% .
