Claim Text:
1. A method for reducing a signaling load of a General Packet Radio Service (GPRS) core network system, wherein the GPRS core network system comprises a first User Equipment (UE); a first Radio Network Controller (RNC); a first Serving GPRS Support Node (SGSN); a first core network node, the first core network node being either a Gateway GPRS Support Node/Packet Data Network Gateway (GGSN/PGW), or a Serving Gateway (SGW); and a first Internet Protocol (IP) network, the method comprising: receiving by the first SGSN one or more service requests from the first UE; measuring by the first SGSN the number of service requests from the first UE to the first SGSN in a predetermined measurement interval of time; determining by the first SGSN whether the measured number of service requests in the predetermined measurement interval of time exceeds a threshold value; setting up a 3rd Generation Direct Tunnel (3GDT) communication if a configuration of the first SGSN allows the setup of the 3GDT communication and the number of service requests from the first UE to the first SGSN does not exceed the threshold value; and setting up a non-3GDT communication for the GPRS core network system if the number of service requests from the first UE to the first SGSN exceeds the threshold value, wherein the first UE is arranged to be in communication with the first RNC, wherein the first RNC is arranged to be in communication with the first SGSN for non-3GDT communication of the GPRS core network system or the first core network node for 3GDT communication of the GPRS core network system, wherein the first SGSN is arranged to be in communication with the first core network node, and wherein the first core network node is arranged to be in contact with the first IP network.
