A smart 3GDT schema has been disclosed, in detail, a method for controlling the communication of a network system has been disclosed. The network system comprises a UE, a NodeB, a RNC, a SGSN, and a GW. The UE is arranged to be in communication with the RNC via the NodeB, and the RNC is arranged to be in communication with the SGSN which in turn being arranged to be in communication with the GW for non-3GDT communication of the network system, or the RNC is arranged to be in communication with the GW for 3GDT communication of the network system. In this method, statistics of payload transferred between the UE and the GW has been monitored, and if the statistics of payload within a predetermined time period exceeds a first threshold, and the UE is in the non-3GDT communication, then switching the non-3GDT communication to the 3GDT communication. The present application has also disclosed the SGSN, GW, and the network system adaptive to perform the method.

Methods and nodes for improved network signaling

The present invention relates to a method for improving IP fragmentation and transmission of user payload between a User Equipment, UE (), and a Peer Node, PN (). The payload is transmitted through a transmission path enabled by at least a first () and a second () established tunnel, said tunnels connecting a first (), () and a second () node in a Packet Core Network, PCN. The method comprises the steps of: The first node () fragments () at least one received payload packet () into fragments () on the basis of a minimum Maximum Transmission Unit, MTU, for an upper IP layer of the transmission path. The first node () encapsulates () said fragments at the entry of the first tunnel (). What particularly characterizes the method is that it further comprises a step where the first node () determines () the MTU for the upper IP layer of the transmission path on the basis of an MTU of a lower IP layer of the transmission path and on the basis of the size of at least one additional tunnel header for the encapsulated fragments ().
