摘要： The present invention relates to a method for improving IP fragmentation and transmission of user payload between a User Equipment, UE (10), and a Peer Node, PN (14). The payload is transmitted through a transmission path enabled by at least a first (17,18) and a second (17,18) established tunnel, said tunnels connecting a first (11), (13) and a second (11, 13) node in a Packet Core Network, PCN. The method comprises the steps of: - The first node (11,13) fragments (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. - The first node (11,13) encapsulates (20) said fragments at the entry of the first tunnel (17, 18). What particularly characterizes the method is that it further comprises a step where the first node (11,13) determines (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).
