Furthermore, the MME 100 may transmit, to the eNB 70 or the UE 60, at least one of a quota, rate control, and a charging policy, and the eNB 70 or the UE 60 may perform traffic control relating to control data transmitted from the UE 60 to the AS 130.

Now, a modification example of Example Embodiment 2 is described. Flow of processing of sending information relating to a transmission data amount according to the modification example of Example Embodiment 2 is described by using FIG. 6. First, the AS 130 determines, as a parameter relating to the UE 60, at least one of a quota, rate control, and a charging policy (S11_1). Note that each of the parameters may include a tariff in the following description as in Embodiment 2, and details thereof are omitted.

Next, the AS 130 transmits, to the SCEF 110, an NIDD configuration request message in which the parameter determined in step S 11_1 is set (S12_1). The NIDD configuration request message may be a T 8 set suggested network configuration request message. Rate control set in the NIDD configuration request message (S12_1) is data control suggested by the AS 130 on a core network.

The SCEF 110 holds, as management data for the UE 60, the quota, the rate control, and the charging policy set in the NIDD configuration request message (S12_1) (S13_1).
