Additionally, 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 user data transmitted from the UE 60 to the AS 130.
Furthermore, although the above description mainly describes a configuration using LTE as a wireless communication method and using EPC as a core network, processing in FIGS. 3 and 6 may be executed in a communication system so called 3G in 3GPP. Specifically, in a communication system called 3G, a node B (NB) is used instead of an eNB, and a serving general packet radio service support node (SGSN) is used instead of an MME. Further, in a communication system called 3G, a gateway general packet radio service support node (GGSN) is used instead of a PGW, and a home location register (HLR) is used instead of an HSS. In the following description as well, a communication system of 3G may be used.
Example Embodiment 3
Now, flow of processing of sending information relating to a transmission data amount according to Example Embodiment 3 is described by using FIG. 7. Steps S 21 to S 23 are similar to steps S 11 to S 13 in FIG. 3, and therefore, detailed description thereof is omitted.
