Furthermore, the MME 100 may transmit, to the UE 60, at least one of a quota, rate control, and a charging policy that has been held. For example, in attach processing or tracking area update (TAU) processing, the MME 100 may set at least one of a quota, rate control, and a charging policy in a message transmitted to the UE 60. In this case, instead of the MME 100, the UE 60 may perform traffic control relating to data transmitted to the AS 130. The UE 60 may perform traffic control relating to user data transmitted to the AS 130, in addition to control data transmitted to the AS 130. Alternatively, the UE 60 may only perform traffic control of either control data or user data. Note that, when receiving a tariff, the MME 100 may transmit the tariff to the UE 60. In this case, the UE 60 may perform traffic control in consideration of the tariff.
