1. A method for controlling a network system, the network system comprising a user equipment (UE), a nodeB, a Radio Network Controller (RNC), a Serving GPRS Support Node (SGSN), and a gateway (GW), wherein the UE is arranged to communicate with the RNC via the nodeB, and the RNC is operable to communicate directly with one or more of the SGSN and the GW, the method comprising:determining, by the SGSN, a data statistic related to data received by the SGSN and transmitted by either the UE or the GW;
determining, by the SGSN, whether the determined data statistic exceeds a first threshold, wherein the first threshold is independent of any data volume statistic determined by or for the SGSN; and
establishing, by the SGSN, a 3G Direct Tunnel (3GDT) between the RNC and the GW for carrying user plane data transmitted by the UE and user plane data transmitted to the UE in response to determining that the determined data statistic exceeds the first threshold.
