Problems solved by technology

[0004] However, in the prior art, in order to realize the automatic allocation function of IPv6 addresses, it is necessary for the SMF to respond to the NS message and the RS message sent by the UE, and then the SMF forwards the NA message and the RA message to the UE through the UPF, resulting in the breakdown of the entire IPv6 address automatic allocation process. High processing delay

Abstract

The embodiment of the invention discloses a data transmission method, a user plane network element and a control plane network element, which can effectively reduce the processing time delay of an automatic address allocation process and reduce the interactive data volume between the user plane network element and the control plane network element. The method provided by the embodiment of the invention comprises the following steps: the user plane network element receives IPv6 address prefix information which is sent by the control plane network element and corresponds to user equipment (UE);if the user plane network element receives a target request message sent by the UE, the user plane network element generates a target response message carrying the IPv6 address prefix information andsends the target response message to the UE, the target request message comprises a routing request RS message, and the target response message comprises a routing announcement RA message.

Description

technical field [0001] The present application relates to the communication field, in particular to a data transmission method, a user plane network element and a control plane network element. Background technique [0002] The 5G network architecture has readjusted the network architecture of the next-generation core network equipment. Usually, the 5G core network control plane (next generation control plane, NG-CP) will provide related functions externally through service interfaces. The session management function entity (session management function, SMF) of the NG-CP and the user plane function entity (userplane function, UPF) perform message interaction through the N4 or Sx interface, realizing the control plane (control plane, CP) to the user plane ( user plane (UP) user policy delivery and event reporting and processing from UP to CP. [0003] In the current automatic address assignment process of Internet protocol version 6 (IPv6), user equipment (user equipment, UE...
