Accordingly, customers who have purchased Slice can check each subscriber's subscription level (Premium, Regular, Free) and perform individual speed control to lower the service delivery speed delivered to Subscriber 1 (Customer#1), which is a free level.

In this case, it can be seen that the service provision speed of the subscriber 1 (Customer #1) is lowered as shown in FIG. 4(b), while the quality of other subscribers is recoverable.

In addition, when control of a specific slice purchased by a customer is required, the controller 52 may block traffic for each service provided in the slice or perform service traffic control to adjust the amount of available traffic.

In this regard, FIG. 5 exemplarily describes service traffic control according to an embodiment of the present invention.

Referring to this, it can be assumed that the overall quality of the subscriber is lowered as shown in FIG. 5 (a) in a specific slice in which a mobile Internet service is provided by a mobile virtual network operator (MVNO).

In this case, the virtual mobile communication network operator (MVNO), the customer who purchased the slice, can check the traffic volume of SVC#2, a specific OTT service, for example, and confirm that the amount of traffic exceeding the range previously contracted with the MVNO is have.

At this time, the virtual mobile communication network operator (MVNO) can perform service traffic control that sets a rate limit on the traffic going to SVC#2, and through this, the quality of all subscribers can be restored overall as shown in Fig.5(b). You can see that you can.
