Abstract

A charging control method and system are provided that can reduce the processing load on a function of performing charging control. The charging control system includes a policy and charging rules function (PCRF), a plurality of gateways (P-GWs) each including a policy and charging enforcement function (PCEF), and a relay section including a relay server and a switch that connects the PCRF and the plurality of PCEFs in a hierarchical manner. The PCRF is directly connected to the relay section, whereby the number of sessions is reduced.
