As described above, the HSS 120 according to the modification example of Example Embodiment 2 can receive, from the SCEF 110, at least one of a quota, rate control, and a charging policy. Further, through movement management of the UE 60 operating after completion of this operation, and session management, the HSS 120 becomes able to send at least one of the quota, the rate control, and the charging policy to the SCEF 110, the PGW 90, and the UE 60. Moreover, the HSS 120 can perform, in consideration of a traffic characteristic of an application operating between the AS 130 and the UE 60, traffic control relating to data transmitted from the UE 60 to the AS 130, and user data transmitted from the AS 130 to the UE 60. When sending at least one of the quota, the rate control, and the charging policy to the SCEF 110, the HSS 120 may use an insert subscriber data request message. Moreover, when sending at least one of the quota, the rate control, and the charging policy to the UE 60, the HSS 120 may send via the SCEF 110 by using protocol configuration option (PCO). By performing traffic control in consideration of a traffic characteristic of an application operating between the AS 130 and the UE 60, the SCEF 110, the PGW 90, and the UE 60 according to the modification example of Example Embodiment 2 can reduce a possibility of occurrence of a problem that a service itself provided by the application fails to operate. The problem that a service itself provided by the application fails to operate is caused by performing traffic control which does not consider a traffic characteristic of an application operating between the AS 130 and the UE 60.
