USER PLANE DATA TRANSMISSION METHOD, MOBILITY MANAGEMENT NETWORK ELEMENT, EVOLVED NODE B AND SYSTEM

摘要

The present invention relates to a user plane data transmission method, a mobility management entity, an evolved NodeB, and a system, where the method includes: setting up a radio access bearer connection with a radio access network node; and performing user plane data transmission with the radio access network node by using a user plane protocol stack, where the user plane protocol stack includes a physical layer, a data link layer, and a network layer, where the network layer includes an IPv6 header and a flow label of the IPv6 header carries a user plane tunnel endpoint identifier TEID, or the network layer carries a type identifier of a GTP-U header. The present invention simplifies network layers of radio access, and can reduce overheads of network transmission, increase proportion of user payload, reduce complexity of a user data processing device, and improve data transmission efficiency of radio access.
