摘要： The present invention relates to a method for signalling in an infrastructure network comprising a Source Serving Node (S-SN), a Target Serving Node (T-SN), and a first Gateway. At least one Packet Data Network (PDN) bearer is established for a User Equipment when at least one PDN bearer is handed over from the S-SN to the T-TN. The network performs the steps of: sending, by the T-SN to the first GW, a modify bearer request indicating that the T-SN does not support dual Internet Protocol (IP) addressing for said PDN bearer being handed over; initiating, by the first GW on the basis of the received modify bearer request, a modify bearer procedure where a new PDN bearer type for single IF addressing is defined; and sending, by the first GW to the T-SN, a modify bearer response comprising information about the new PDN bearer type.

摘要： For improved IP fragmentation and transmission, user payload is transmitted through a transmission path enabled by at least a first established tunnel (17,18) and a second (17,18) established tunnel. The tunnels connect a first node (11, 13) and a second (11,13) node in a Packet Core Network (PCN). A method comprises the first node fragmenting (19) at least one received payload packet (15) into fragments (16) on the basis of a minimum Maximum Transmission Unit (MTU) for an upper IP layer of the transmission path; encapsulating (20) the fragments at the entry of the first tunnel, and, determining (21) 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 (16).

摘要： A smart 3GDT schema has been disclosed, in detail, a method for controlling the communication of a network system has bee 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.
